Agência FAPESP – Highly concentrated aqueous electrolytes, known as water-in-salt electrolytes, could be an alternative to the organic solvents used in car batteries and other electrochemical devices. Abundance and, hence, low cost are key factors in this application, alongside nontoxicity, according to the review article “Water-in-salt electrolytes for high voltage aqueous electrochemical energy storage devices” published in the journal Current Opinion in [...]

Researchers at the Federal University of São Carlos (UFSCar) in Sorocaba (state of São Paulo, Brazil) have developed a technique to diagnose early-stage multiple sclerosis, a disease of the central nervous system, and distinguish it from neuromyelitis optica, a rare yet severe autoimmune inflammatory process also affecting the central nervous system. The immune system of a person with these diseases produces antibodies that attack and damage part of the myelin sheath, an [...]

Researchers from the University of São Paulo (USP) in Brazil have developed a strategy for treating the most aggressive type of brain cancer in adults that combines a photoactive molecule and a chemotherapeutic agent – both encapsulated in protein-lipid nanoparticles. Results of the research, supported by São Paulo Research Foundation – FAPESP, were presented during the FAPESP Week France symposium, by Antônio Claudio Tedesco , of the Center for Nanotechnology, [...]

The second law of thermodynamics states that the total entropy of an isolated system always tends to increase over time until it reaches a maximum. In other words, disorganization increases without outside intervention. Even the best electrical equipment inevitably heats up, as part of the energy that should be converted into mechanical work is dissipated in the form of heat, and supposedly inanimate objects deteriorate as time progresses but do not spontaneously regenerate. However, this [...]

France is one of the main international partners in research projects supported by the São Paulo Research Foundation (FAPESP), which has cooperation agreements with 15 French funding agencies, universities, research institutions and companies. More than 120 research projects have been approved under the auspices of these agreements. To celebrate the partnership and stimulate new collaborations in the most diverse knowledge areas, FAPESP Week France will be held on November 21-27, 2019, [...]

HOUSTON – (Nov. 13, 2019) – A lightweight material full of holes is nearly as hard as diamond. The mere dents left by speeding bullets prove it. Researchers at Rice University’s Brown School of Engineering and their colleagues are testing polymers based on tubulanes, theoretical structures of crosslinked carbon nanotubes predicted to have extraordinary strength. The Rice lab of materials scientist Pulickel Ajayan found tubulanes can be mimicked as scaled-up, 3D-printed [...]

Flexible electronics is one of the most important trends in technology today. The market is growing so fast that it is expected to double in value in the next decade. Extremely light and even bendable optoelectronic equipment that supplies, detects and controls light will become commonplace in the near future. A great deal of research is progressing in this direction, as exemplified by a paper recently published inScientific Reports. The paper describes an experimental and theoretical study [...]

The use of solid-state refrigerators to cool appliances and electronic devices is a possible technological application for a theoretical study conducted at the University of Campinas (UNICAMP) in São Paulo State, Brazil. Although this application is not considered in the study, which was based on computer simulations, such applications are on the horizon and could be an efficient and environmentally friendly alternative to vapor-compression refrigerators, which currently dominate the [...]
