Sorry, this entry is only available in Brazilian Portuguese.

Check out the highlights of some symposiums according to their organizers.

Symposium D: Advanced materials applied in sensors for health, agricultural, and environmental applications.

Our symposium featured the presentation of approximately 130 papers, 28 of which were oral. We had a presentation by 4 invited speakers from Spain, England, Austria, and Brazil. Regarding oral presentations in the form of posters, we had the participation of Brazilian researchers from practically all regions. Thirteen students submitted their work to compete for RCS and ACS awards. Notably, one of the competitors was selected to receive both awards.

In summary, the objectives proposed for this symposium were fully achieved.

 

Symposium G: Photocatalytic materials applied in energy conversion and environmental remediation.

162 works were presented, 134 works in the form of posters, 23 works in the form of oral presentation and 5 lectures (invited lecture), with the presence of 2 renowned speakers from abroad: Dr. Conchi Ania from the University of Orléans – France and Dr. Andrea Folli from Cardiff University- United Kingdom.

Of the 162 participants in Symposium G, 69 were from the Northeast region, 60 participants from the Southeast region, 19 from the South region, 4 from the North region, 2 participants from the Center-West of Brazil and 8 from abroad. 9 students competed for prizes, being awarded a prize for the presentation in the form of a poster and a prize for the oral presentation.

This Symposium promoted interaction between researchers and students on advances in the development of new nanostructured materials for the conversion and storage of solar energy, mainly photocatalytic materials for solar water splitting for hydrogen production, conversion of CO 2 into fuels and environmental remediation.

 

Symposium H: New developments in battery materials: designing and producing more efficient systems via nanoscale characterization.

The Symposium H and the workshop of 2023 B-MRS meeting focused on the latest advances and challenges in the field of battery materials and were held successfully.

Both events gathered a good number of participants. The symposium featured 4 high- level invited speakers from Harvard University, University of Lisbon, Wien University and Thermo Fisher Scientific, 5 oral presentations with one from Thermal Fisher Scientific, one from Italy and 3 from different institutions of Brazil and 10 posters.

There were two invited speakers from China and one invited speaker from USA who could not make their trip due to visa issues. There were less participants than we expected, and the main reason might be that there were three similar symposia for energy storage materials. We believe that the research about battery materials would be significantly boosted in the next years due to the discovery of the Lithium ore in Bazil and thus, a battery symposium will attract a larger interest in the future, namely participants from Industry. Another point that we would like to address is the student awards. There were only a few extended abstracts submitted for awards. We visited all the posters and asked why the students did not apply for the award and the answer was lacking courage. In this case, we should really encourage all the students for extended abstract submission. Overall, the symposium and the workshop were successful, and the symposium organizers would like to thank all the speakers, participants, sponsors and reviewers for their contribution to the success of the event.

 

Symposium R: Organic electronics, photonics and bioelectronics: fundamentals, applications and emerging technologies.

Symposium R on organic electronics, photonics, and sensing applications was an outstanding success, showcasing the vibrant and innovative landscape of research in this field. We were honored to host renowned international researchers who delivered inspiring talks, shedding light on the cutting-edge developments in this area. The impressive talks from Brazilian presenters highlighted the exceptional quality of research carried out in the country, despite the persistent funding cuts we have faced in recent years. Moreover, the contributions from our talented student speakers demonstrated the remarkable potential of the next generation in advancing the field and filled us with hope for the future of research in Brazil. Symposium R was a true demonstration of the collaborative spirit of our community, and we look forward to replicating its success next year in Santos.

 

Symposium U: Sustainable production of nanomaterials and ink formulations for affordable, efficient, and reusable printed electronics.

The XXI BMRS Symposium U received a total of 25 submissions, of which 8 were oral presentations covering a wide range of topics. These submissions were mainly represented by bright young researchers from Brazil. In terms of invited talks, the symposium was marked by high-level presentations from international researchers, namely Dr Sergio Pinilla from the Madrid Institute for Advanced Studies (IMDEA); Prof. Jeff Kettle from the University of Glasgow; Dr Emanuel Carlos from CENIMAT, Universidade Nova de Lisboa and Dr João Coelho from CENIMAT, Universidade Nova de Lisboa/Facultad de Física, Universidad de Sevilla. These were high-quality presentations that led to a very fruitful discussion session. In fact, in all the presentations, with an audience of around 50 people, there were always interesting questions for the speakers, which raised the scientific level of the symposium. It is also important to mention that Merck also had a representative, Carla Decandio, at the symposium. This participation provided a very interesting overview of how big companies are trying to move towards sustainable chemicals and green-printed electronics.

In terms of awards, the oral presentation “Electrodeposition of manganese oxide on paper-based laser-induced graphene for sustainable supercapacitor fabrication” by PhD student Maykel dos Santos Klem ((FCT-UNESP)) was awarded the Bernhard Gross Prize for Best Symposium Presentation. The best poster award went to Júlia Ketzer Majewski (UFPR).

Overall, the symposium was a success and hopefully an inspiration for all young researchers interested in sustainability and printed electronics.

 

Symposium V: Advanced nanocomposites for photonics : materials synthesis, optical properties and applications.

The symposium focused on recent developments of photonic nanocomposites: synthesis, characterization and potential technological applications. Overview of recent works and experiments that are still being conducted were presented based on advanced nanocomposites: glasses, glass-ceramics, colloids, two-dimensional materials, photonic crystals, hybrid systems, flexible and nanostructured thin films, quantum dots, among others. Several applications for photonics were highlighted as follows: nanothermometry, color displays, optical amplifiers, photovoltaic devices, magneto-optical sensors and random lasers

Poster sessions occurred (October 2nd to 4th) with 70 presentations; the work about tellurite glasses doped with Er3+ ions with potential for thermometry sensing applications, presented by Gaston Lozano Calderón, from Instituto de Física de São Carlos (São Paulo-Brazil), received the Bernhard Gross Award for poster presentation. Oral sessions took place from October 2nd to 5th with 37 presentations, including 14 invited lectures from Brazil (3), Canada (1), Italy (2), France (2), Mexico (1), Spain (1), and USA (4). João Antonio Oliveira Santos, from Universidade Estadual Paulista Júlio de Mesquita Filho, received the Bernhard Gross Award for the oral presentation about smart nanohybrid platform for temperature sensing. It is important to emphasize the broad audience in all the sessions and the permanent interaction with the presenters. The enthusiasm of the students deserves to be mentioned and motivates all of us to continue persistently.

Year 10, issue 8. September 8th, 2023.

History Article by the founding president of B-MRS, Prof. Guillermo Solórzano (PUC-Rio), gathers information on B-MRS annual meetings, from the 2002 Inaugural Meeting, which had 400 participants from 18 countries, to the XIX B-MRS Meeting, held in virtual format during the pandemic with more of 1,000 attendees. The article concludes that the B-MRS Meeting has become the main interdisciplinary event for research in Materials in Brazil. Know more. Papers by the community This perspective article, signed by a team from UNESP and USP, addresses recent advances in the encapsulation of bioherbicides using micro and nanoparticles. Key pieces in sustainable agriculture, bioherbicides are products based on microorganisms and their derivatives, used to inhibit the growth of weeds and, therefore, increase the productivity of crops. Despite their numerous benefits, many bioherbicides are susceptible to degradation by environmental factors, a fact that has encouraged the development of encapsulation techniques with the aim of extending the useful life of these compounds, as well as increasing their effectiveness by controlling the release of active ingredients. Learn more in the article at ACS Sustainable Chemistry & Engineering. Magnetic structures like skyrmions are essential components to develop the next-generation spintronic devices. In this work, researchers from USP, LNLS and UFPA, together with collaborators from Sweden, investigated the origins of skyrmion formation in a multilayer material. Using a combination of computer simulations and results from various experimental techniques, the authors showed that interfacial atomic intermixing is essential for the formation of skyrmions. The work opens perspectives in the development of materials for spintronics. Access the paper at Nano Letters. In this article, USP researchers and collaborators report an important step in the development of biomaterials for bone regeneration. Using collagen and carrageenan (a polysaccharide extracted from seaweed), the authors produced structures that mimic the organic part of a natural bone matrix, properly fulfilling the function of promoting bone tissue mineralization. The work shows the potential of using these structures as organic matrices for bone implants and for studies on mineralization. Check out the paper in Biomacromolecules. Electronic ceramics can be used to produce membranes capable of separating gases through the process of permeation (the penetration of gas molecules through the membrane). In this way, it is possible, for example, to separate carbon dioxide from other compounds in order to reduce the emissions of this greenhouse gas into the atmosphere. In this article, IPEN researchers present a system to assess the efficiency of these ceramic membranes. The system simultaneously evaluates the permeation of the material and its electrical properties. The work was awarded in June this year at the 67th Brazilian Congress of Ceramics. Go to the full article in Membranes. Hydroxyapatite coatings are important on titanium implants because they improve their integration into the body and increase their useful life. Currently, plasma spray technique is the most used technique to coat commercial implants, but the equipment that is used in the process is expensive. In this article, a scientific team from UFRGS and UFN presents a low-cost method that could replace plasma spray. The technique is based on a simple brush painting. The coating obtained by the authors complies with all ISO standards for implant coatings. Access the paper at Ceramics International. In this work, the authors used defect engineering (the controlled introduction of defects in the structure of a material) to modify the optical and surface properties of zinc oxide (ZnO) – a material of great technological and industrial interest. The team, made up of researchers from UFOP, UNIFAL and USP and collaborators from Spain and Finland, doped zinc oxide with different concentrations and atmospheres of manganese and cobalt (two transition metals) and studied their properties in detail.

It took two years of dedicated planning, visiting different materials research groups all over Brazil and in continuous email discussions, for the Brazilian Materials Research Society, BMRS (named in Portuguese as SBPMat for Sociedade Brasileia de Pesquisa em Materials) to be founded on June 26 in an assembly meeting in Rio de Janeiro and over internet.

A year later, from July 7th to 10th 2002, almost 400 scientists, from 18 countries, gathered in Rio de Janeiro, at the Carlton Rio Atlantica Hotel and Convention Center, for the inaugural meeting of the Brazil MRS, with English as the official language. It is thus clear the international environment of the meeting. In fact, the foreign participants included the presidents of MRS (Alex King) and the European MRS, E-MRS (Giovani Marletta), as well as the General Secretary of the International Union of MRS, IUMRS, (Robert P. Chang). Chaired by the founding president Guillermo Solórzano (Catholic University of Rio de Janeiro), the program committee assembled five symposia ranging from nanostructured Materials and System to Semiconductors and polymeric thin film materials. The program included plenary sessions and a workshop on the processing of powder materials. Slightly more than 400 technical presentations were made either orally or as posters, displayed in a neighboring area of a commercial exhibition, engaging the attendees into lively discussions. The meeting emphasized international materials collaborations, which were the themes of three plenary sessions. RP Chang described his vision of a Materials World Net to complement efforts of international materials research collaborations; Adrian the Graff of the US National Science foundation, NSF, and Celso P. de Mello of Brazilian founding Agency, CNPq, described the creation of mechanisms for joint funding towards establishing , with other governmental agencies, an Inter-American Materials Collaboration Program. At the closing session the SBPMat governing body announced that, in view of the success of this conference, the society will make this meeting an annual event.

On October 26th-29th 2003 the second BMRS meeting took place also in Rio de Janeiro. The program, augmented to six symposia, covering a wider spectrum of subjects including on Nanostructured and Biomaterials II, Materials for energy conversion and environmental protection, Structural alloys for transport systems, composite and supramolecular materials, and a workshop on Semiconductors group III nitrides. High light of this meeting were two plenary sessions on international collaboration: one session in the scope of the Inter-American Collaboration Program –CIAM, with authorities of the Brazilian funding agencies CNPq and FINEP, the NSF and MRS president (also representing the US National Academy of Sciences). The event also hosted a Pan American Advanced study institute, funded by NSF, with the participation of students from Brazil, the US and other Latin American countries. The meeting also provided a commercial exhibition of products and services of interested to the community of materials researchers. With close to 500 participants and held at the Pestana Rio Atlantica Hotel Convention Center, on Copacabana beach with Rio other sights closed by, the meeting provided a wide range of opportunities for extra curriculum activities, but nevertheless held the attention of a well-engaged audience.

The proceedings of the 1st and 2nd Brazil MRS Meetings were published in two journals: Materials Characterization and Materials Research. The former selects contributions mainly concerning materials microstructure and properties. The later, a journal with a larger range of subjects, consider contributions dealing with theory, modeling, phenomenological studies and experimental papers on synthesis, processing, performance and applications of materials.

Brazil is country of continental dimensions with several options for venues to host BMRS meetings. An important defining criterion, however, is to offer an appropriate relaxing environment with hotels and convenient accommodation for students, local tourist attractions together with a ready access to an International airport. So the 3rd BMRS was held in world famous Iguassu Falls, south west of Brazil, from October 10th -13th 2004 at Hotel Bourbon Cataratas and Convention Center. The meeting consolidated the symposium model and the Program committee successfully organized a set of topics enhancing the interdisciplinary scope of materials research in 9 symposia, covering theory and frontiers on experimental research, from solid state chemistry to environmental sciences applied to materials. One workshop on Spintronics in Semiconductors was also included. Joining efforts with sister scientific societies and lead by Elson Longo (Federal University of Sao Carlos), BMRS president in this year, other well-stablished materials-related events were incorporated in this BMRS edition: the IV Brazilian Symposium on Electroceramics and a Symposium on Nano-scale structural Characterization of Materials, hosting the bi-annual MICROMAT meeting, which is a traditional event of the Brazilian Society for Microscopy and Microanalysis- SBMM. Three plenary lectures presented New Developments in Nanotechnologies (Cylon Gonçalves da Silva, General Secretary, Ministry of Science and Technology- MCT, Brazil), the Atomistic Structure of Internal Interfaces (Manfred Ruhle, director Max Plank Institut, Germany) and on International Cooperation on Nanotechnologies (Dietling Jering, The European Union). The number of registered participants at this 3rd Meeting was close to 1000.

The 4th BMRS Meeting moved to Recife, an important and historical capital in the north east of Brazil, October 16th-19th 2005. The program committee, chaired by Celso P. de Mello and Anderson S.L. Gomes (Federal University of Pernambuco), successfully set up 8 symposia, all on interdisciplinary topics, including 37 invited talks by national and international scientists, 157 oral and 599 posters presentations, providing a total of 793 technical contributions, involving over 800 participants in the meeting. The opening session had as the Keynote Speaker Prof. Sérgio Rezende, the Brazilian Minister of Science and Technology, a world renowned materials scientist himself. Four Plenary Lectures were also delivered by international experts in different themes of materials research: Atomic-scale Defect Analysis of Ceramic Materials (Barry Carter – Department of Chemical Engineering and Materials Science University of Minnesota, US), Construction of Molecular Nano-Structures and Electronic Properties (Takuji Ogawa , Center for Molecular-Scale Nanoscience, Institute of Molecular Science, IMS/Okazaki, Japan), Multifunctional Organic/Inorganic Hybrids (Luis A. Ferreira M. Dias Carlos, Department of Physics, Universidade de Aveiro. Portugal), and from High-Temperature Superconductivity to Complex Electron Systems Science (H. Takagi, Magnetic Materials Laboratory, RIKEN’S Discovery Research Institute). A well-attended roundtable discussion session was included in this year’s program, aiming at stablishing the perspectives of the materials science area in Brazil. As in previous years, the meeting also offered a commercial exhibition.

The efforts to provide the society with a professional administration structure, initiated in 2006 with Fernando Lazaro F Jr (Catholica University of Rio de Janeiro) as president of BMRS, proved to be productive regarding the communication required for the organization of the following meetings. So the 5th BMRS Meeting was successfully held at Costao do Santinho Resort and Spa in Florianopolis, a city of spectacular natural scenarios in in the south of Brazil, October 8th-12th 2006. Under the coordination o Aloisio N Klein (Federal University of Santa Catarina, UFSC), the program reached 13 symposia. In parallel, a well-attended commercial exhibition stimulated the attendee’s interest on experimental materials research. This 5th edition was organized jointly with the MICROMAT meeting, contributing with 4 symposia to the event overall and enriching the 1scope of topics and the key note lectures, such as the one delivered by the president of the International Federation of Microscopy Societies –IFSM (Cristian Colliex, Orsay, France) . This meeting also hosted the International Symposium on Hybrid Materials, chaired by Antony Cheetham (University of Santa Barbara, US), and the 5th Brazilian Symposium on Electroceramics, chaired by R. Muccillo (IPEN, SP) and JA Varela (UNESP, SP) As a result, a record number of 1166 submitted abstracts and a about 1000 participants proved this annual meeting to constitute the most important Brazilian conference of Materials Science and Engineering.

The following year, for the 6th edition, the meeting moved again to the North Easter region of Brazil, being held in the exuberant city of Natal at SERHS Grand Hotel and convention center, October 28th –November 1st 2007. Coordinated by Dulce M de Araujo (Federal University of Rio Grande do Norte- UFRN) the program consisted of plenary lectures and 10 symposia covering a wide range of topics, ranging from nanomaterials to superconductors, including organic semiconductors, multiferroic materials, catalysis, and computational modeling of materials. The meeting had 1057 submitted abstracts nearly reaching again one thousand participants, with significant numbers of delegates from abroad, namely form Latin America and Europe. The commercial exhibition has continued to increase in number of stands and gained the name of VI Expomat.

The seventh annual Meeting was held in Guaruja, a beach resort in the state of Sao Paulo, Southeast of Brazil, at Casa Grande Hotel Resort and Spa, Praia da Enseada, September 28th – October 2nd 2008. Chaired by Aldo Craievich (University of Sao Paulo-USP) and Reginaldo Muccillo (Institute for Nuclear Energy Research-IPEN) the program offered 8 plenary lectures delivered by outstanding scientists and successfully sat up 14 symposia, including 5 symposia in partnership with MICROMAT meeting, and one microscopy pre-meeting course. With a total of 1417 submitted abstracts, the meeting reached a record of 1284 registered participants including about 700 graduate and undergraduate students! Two MRS journalist covered this meeting in loco and reported it in a 2008 issue of the MRS Bulletin.

In 2009 Rio de Janeiro hosted the International Conference of Advanced Materials, ICAM 2009, for the first time in South America, with Guillermo Solórzano (Pontifical Catholic University of Rio de Janeiro, PUC-Rio) and Elisa B Saitovitch (Brazilian Center for Physics Research) as chairs. ICAM is the most prestigious conference of the International Union of Materials Research Societies (IUMRS) and in 2009 was organized together with the 8th Brazilian MRS Meeting from 20th to 25th September 2009. Twenty eighth technical symposia, 8 plenary lectures, 2 workshops, an Energy Forum and an Exhibition composed the program. Each symposium featured invited talks, contributed oral and poster presentations. About 2000 scientists from 47 countries gathered at Windsor Convention Center in Rio, during this event. The 28 Symposia were assembled in seven major areas: Nanoscience and Nanotechnologies, Health and Biological Materials, Energy and Environment, Functional and Electronic Materials, Structural Materials, Theory and Phenomena, and General Interest. The meeting opened with an official ceremony which included address talks by the president of the Brazilin MRS, the Program Committee Chair, the Conference Chairman and Brazilian government authorities. The state ministry for Science and Technology delivered the opening lecture. All the oral presentation were delivered in English, which emphasized the international flavor of the meeting. As in previous BMRS meetings, a poster session was held each evening and a there was also an equipment exhibition. More than 1800 technical presentations were made (485 orally and 1374 posters) and the strong interdisciplinary program provoked lively discussions both in the formal sessions and informally and in the formal session. The conference also featured two workshops “Innovation in Materials Research “and “Global Nanotechnology Network” and an Energy Forum. The commercial exhibition has doubled in terms of space and number of stands.

The BMRS entering its nine year of existence, the Brazilian materials research community was accustomed to the annual meeting. From 24th – 28th October 2010 the 9th BMRS meeting takes place in Minas Gerais, an important Brazilian central state, in Ouro Preto, a patrimonial city recognized by UNESCO, at UFOP Arts and Convention Center. Chaired by Margareth Spangler Andrade (Center for Technology of Minas Gerais , CETEC – MG) and Evando Mirra de Paula e Silva (Federal University of Minas Gerais UFMG/CGEE) the event offered an interdisciplinary program of 12 Symposia and 6 plenary lectures delivered by distinguish invited speakers. With a new record of 1766 submitted abstracts, 195 presentations were delivered orally and 1456 as posters, the meeting reached a 1562 registered participants, including graduate and undergraduate students!

The 10th edition of the BMRS meeting was held in Gramado, an emblematic mountain region city in South of Brazil, at the Convection Center of Federal University of Rio Grande do Sul, October 25th- 29th 2011. The program and meeting committee chaired by Paulo F Fichtner and Naira M Balzaretti (Federal University of Rio Grande do Sul) arranged 16 symposia in a wellbalanced spectrum of subjects, 9 plenary lectures delivered by distinguished scientist from Brazil and abroad, and 3 pre-meeting courses on Advanced X ray diffraction techniques. Celebrating the occasion of the 10th meeting, BMRS president, Jose A Varela, inaugurated the “Joaquim da Costa Ribeiro Memorial Lecture” and presented an award in recognition for accomplishments serving the society to founding President Guillermo Solórzano and to former state ministry for Science and technology Sergio M Rezende. This year, numerical output continued to increase both in terms of submitted abstracts (1907) and presentations (266 oral and 1546 posters) with 1840 registered participants, stablishing a new record for a national meeting. The comercial exhibitions has become a well-established parallel event.

The BMRS meeting has then become a consolidated event in Brazil and known abroad. The symposium–base model has been successfully accepted by the local scientific community and gained increased attention. In the following years the meeting experienced a steady growth in the number of participants, as summarized in the paragraphs bellow, with no less than 20 and up to 40 different countries represented, mainly from Latin America and Europe. The meeting sites have moved year to year across the country, selected by the local arrangement committees. Highlights of the meetings are the continuous participation of renowned scientists as plenary and key note lectures on various state-of-the-art topics in Materials Science and Technologies. No less important has been the involvement of young students both in oral presentations and, more prominently, in the ebullient poster sessions. In fact, aiming at promoting and better organizing student’s participation, the Society successfully established University chapters. On the other hand, the comercial exhibitions has become a wellestablished parallel event.

The 19th BMRS meeting, planned to be held in Foz de Iguazu in 2020, did not take place because of the pandemic year. So it was postponed and held virtually from August 30th to September 3rd 2021 together with the 2021 International Conference on Electronic Materials – IUMRS ICEM 2021. The meeting chairs Gustavo M Dalpian (Federal University of ABC) and Carlos C B Bufon (National Nanotechnology Laboratory) were successful in setting up a full program consisting on 23 symposia, an opening ceremony /memorial lecture, 9 plenary lectures and a Closing ng ceremony awards presentation, besides a pre-meeting school (Young researchers), a workshop (Women in Science) and a parallel virtual exhibition. In addition, a discussion on CBAN- BrazilArgentina Nanotechnology Center was stablished. From the 1003 abstract submitted, 304 were presented orally and 706 as posters with 1307 registered participants including 1038 effective attendees.

In summary, over the past two decades the Brazilian MRS meeting has grown steadily and consolidated as the major interdisciplinary meeting of Materials Science, Technology and Engineering in Brazil. It has reach a reputation that transcends country borders, is continuously attracting international participation, mainly from Latin America, USA and European countries, consolidated as the second Materials Research Meeting in the Americas and perhaps as number 3 in the western hemisphere. The merit of this success is due to the enthusiastic involvement of volunteer society members led by competent and dedicated Brazil MRS executives, with the effective assistance of a small and committed BMRS staff and the electronic and data processing Aptor system, over the years. The continuous support of (older) sister societies MRS and E-MRS as well of IUMRS have provided additional incentive. Recognition for the financial support received periodically from the Federal funding agencies MCT, CNPq, FINEP and CAPES, as well as from the State funding agencies namely FAPESP and FAPERJ for financing part of the infrastructure and granting the students participation. Other state agencies such as FAPEMIG, FAPERGS, and FAPESC have also contributed to local arrangements in their states. On the other hand, the partnership established with the commercial exhibitors, in enriching the success of the meetings, is also acknowledged.

Papers by the community In this article, a scientific team from Unesp and USP makes a contribution to the development of implants that integrate better into the body. The authors studied in detail the possibility of adding bisphosphonates (organic molecules used in the treatment of bone diseases) to materials for dental implant coatings: titanium dioxide (a material with good adhesion to metals such as titanium) and hydroxyapatite (a compound with excellent biocompatibility). Bisphosphonates could make implants more bioactive by increasing their ability to induce bone growth. This work takes a first step in this direction, as it shows how the adsorption of these molecules on films occurs and how this affects surface properties. Check out the paper in Surfaces and Interfaces. Micro and nanofibers that are both flexible and conductive are the subject of this review article signed by a team from UFBA, Embrapa Instrumentação and UFSCar. The authors address recent advances in the development of these materials produced by electrospinning, and their application in flexible electronic devices, from batteries to sensors, increasingly present in health and environmental monitoring. Check out the review in the Chemical Engineering Journal. Researchers from Unicamp and CNPEM, together with a collaborator from Canada, investigated the modulation of acidity in catalysts and its impact on the hydrodeoxygenation reaction – one of the main processes used to add value to biomass derivatives in the production of biofuels. The results contribute to the development of more active, selective and stable catalysts that can be used to produce fuels and raw materials for industry from biomass. Access the paper in Applied Catalysis B: Environmental. A team from UFABC developed a portable device that allows detecting the rabies virus in less than 1 minute. The work presents a new alternative to the current methods of diagnosing the disease, which require a laboratory structure and expensive reagents to be carried out. The authors produced different graphene derivatives from natural Brazilian graphite and tested their performance as biosensor electrodes. Reduced graphene oxide films showed the best performance in tests with respiratory secretions from bats. Functionalized with cDNA, the electrodes detected and quantified the RNA of the virus in the samples. The device is promising for diagnosing diseases in hard-to-reach places, as well as for field research. Access the scientific article in Biosensors and Bioelectronics.

Perovskites are very promising semiconductor materials for use in solar cells and other optoelectronic devices, but they have a limitation that impairs the useful life of their applications, their low stability. In this context, humidity can be considered the enemy of perovskites, as it is one of the main factors that accelerate the degradation of these materials.

Now, a discovery by researchers from the Brazilian Federal University of ABC (UFABC) brings a very different perspective on the interaction of water with perovskites. With a process based on the simple hydration of three-dimensional perovskite structures, the scientists were able to generate two-dimensional (sheet) and one-dimensional (wire) structures, which, in addition to being more stable than 3D structures, have different properties.

“In controlled amounts, the presence of water can be extremely beneficial for the synthesis of new structures in perovskites”, says André L. M. Freitas, postdoctoral fellow and author, together with Prof. José A. Souza, of the paper that reports this work in the Journal of Materials Chemistry C.

The authors produced micrometric cubes of MAPbBr3, a hybrid material (organic – inorganic) from the perovskite family, which is usually used in the academic environment in solar cells and LEDs. In this material, the inorganic part forms an octahedron, where the central atom (Pb) is surrounded by six halides (Br). “The octahedrons are extremely important in these materials, as they are directly responsible for the physical properties of the material”, explains the postdoc.

To generate the wires, the microcubes were placed in water. To produce the sheets, an organic molecule was added to water. In contact with the liquid, almost instantly, the material lost its crystalline structure, forming what the UFABC duo called an intermediate phase. “We faced a great challenge when analyzing this phase, as the process occurs quickly and many times we had to repeat the experiments to properly characterize it”, says Freitas.

Subsequently, when subjecting the material to drying, the water molecules were expelled from the structure and an interesting conversion took place: the material once again had a perovskite structure, but with a morphology and dimension different from the original ones. “That was one of our main contributions; we were able to control the recrystallization process and obtain different structures and dimensions”, says Freitas.

In the formation of the wires, the process inhibited the growth of the crystalline structure in two directions. In the case of the sheets, the organic molecule added to the water acted as a barrier to the growth of the material in one direction, as if it was a spacer between the layers of octahedra, giving rise to a new structure of the 2D perovskite family. Especially in the 2D structures, this confinement, which occurred on a very small scale, restricted the movement of electrons, resulting in very pronounced quantum effects which modified the electrical and optical properties of the material.

“Our observation revealed that dissolved or degraded material can recrystallize into interesting structures”, summarizes Freitas. According to the authors, by exploring the hydration process of perovskites, the work brings new perspectives to advance the understanding of the degradation and recrystallization of these materials, as well as to understand optical properties such as those involving the dynamics of the exciton (the electron – hole pair generated from the excitation of light in the semiconductor).

The work presents a simple, scalable and sustainable process to produce low-dimensional perovskites with controlled properties. The results could impact both application development and the study of the fundamentals of these versatile materials.

The research received financial support from Brazilian agencies FAPESP and CNPq.

Papers by the community In this work, a scientific team from UNESP developed a low-cost material, based on cellulose microfibers, capable of removing toxic dyes present in effluents from the textile industry. The material, which is recyclable, was produced within the circular economy concept from an agro-industrial residue widely available in Brazil, sugarcane bagasse. Go to the paper in Bioresource Technology. Researchers from IFSC-USP and UFES, along with scientists from Colombia, have developed a low-cost, portable biosensor capable of detecting ochratoxin with high sensitivity and selectivity. Ochratoxin is a toxic and potentially carcinogenic substance produced by fungi, often found in coffee beans. A patent application for this development is in progress at the USP Innovation Agency. Go to the paper in Talanta. Scientists from UFSCar and USP presented a new route, based on the “flash-sintering” technique, for obtaining glass-ceramics (materials with high resistance to impacts, obtained by crystallizing common glasses). The team obtained glass-ceramics in much shorter times and lower temperatures than conventional methods: 20 seconds in an oven at 500 °C, instead of a few hours at 950 °C. A patent application for the process has already been submitted in Brazil. Go to the paper in Acta Materialia. A team from five Brazilian and one French institutions developed a technique to characterize chiral organic materials, which can mimic the properties of the chiral molecules that exist in nature, and also can form metamaterials that interact exotically with light. Called Photoluminescent Ellipsometric Circular Dichroism (PECD), the technique makes it possible to distinguish the electronic transitions that are related to the chiral centers of molecules, and it can be combined with Ellipsometric Raman Spectroscopy (ERS).
