Featured paper

Researchers from IFSC-USP and UNIFESP are co-authors of this review article on Langmuir and Langmuir-Blodgett films. In addition to addressing concepts and commenting on the promising applications of the films in molecular machines, organic electronics and tissue engineering, the authors report the history of these materials, including the contributions of two women: Agnes Pockels, an amateur and self-taught scientist whose discoveries were made in her kitchen sink, and Katherine Blodgett, who was the first woman to earn a doctorate in physics from the University of Cambridge and to be hired as a scientist at General Electric.

langmuir 2

A team from USP (IFSC and ICB-II) proposed a possible strategy for the treatment of Covid-19, based on the repositioning of a drug combined with the use of nanotechnology. The solution consists of encapsulating a drug, currently used to treat patients with multiple sclerosis, inside a polymeric nanocapsule capable of releasing the medication into cells infected with SARS-CoV-2. Tests with cells showed that the encapsulated drug has less toxicity than the free one and, at the same time, its antiviral activity against SARS-CoV-2 is almost 70 times higher than that of the drug without encapsulation.

Looking for natural materials that can provide low-cost two-dimensional insulating layers, a team from UFMG, UFOP, Mackenzie, LNLS and UNICAMP investigated the structure and properties of clinochlore – an abundant lamellar mineral. The authors demonstrated that the presence of impurities between the lamellae affects the optoelectronic properties of the material in both its macroscopic and two-dimensional versions. The article points out the potential application of this material in nanodevices production. Access the paper on Applied Surface Science:


Lives & Webinars

A live held for the Brazilian National Science and Researcher Day (on July 8th) brought together three researchers from the Southeast, North and Northeast regions of the country who showed the importance of research in sustainable development. The recording of the panel is available at the B-MRS YouTube.

Professor Hidembergue Ordozgoith from Frota (UFAM) showed how the development of new materials based on the sustainable use of Amazonian biodiversity can contribute to a new economic cycle in the North region, with an impact on segments such as food, agriculture and construction.

Professor Simoni Margareti Plentz Meneghetti (Ufal) presented through several examples the fundamental importance of catalysts to make industrial processes more sustainable, to take advantage of renewable raw materials such as biomass, to enable the use of clean and renewable energy and even to recycle various materials.

Researcher Cauê Ribeiro de Oliveira (EMBRAPA) has shown that developing fertilizers is, in fact, developing materials. In order to achieve the maximum possible efficiency and the necessary properties with the least negative environmental impact and reduced cost, it is necessary to modify the fertilizers with other materials and to use systems that allow them to be released gradually in a controlled manner.
