As the name indicates, metal-air batteries are energy storage devices in which one of the electrodes, the anode, is formed by a metal and the other, the cathode, by air. These batteries promised a leap in capacity as compared to the current ones. The improvement should enable the fabrication of devices with superior performance and same size, or with similar performance and lower size and cost. As metal-air batteries are…
Brazil is the second world producer of ethanol and the first in sugar cane ethanol. This renewable fuel is widely used in the country, where it is sold in all gasoline stations. The novelty is that ethanol can not only fill the tanks of internal combustion engines cars, but also power electric cars. In fact, ethanol can be used to generate hydrogen and, from it, to produce electricity. The process,…
CINE wishes Happy Holidays to All! And a 2021 with New Energies!
With an economy less based on fossil fuels and more supported on electricity, the leading role of batteries, supercapacitors and other energy storage devices increases. And grows the need to improve these electrochemical devices in terms of cost and performance, as well as to adapt them to the needs of different applications– namely of electric cars and electronic devices. One of the promising technologies to this effect is that of…
One of the main obstacles to the production of solar cells from perovskites with commercial purposes is the presence of lead, a toxic element, in its composition. Another limitation is the instability of these materials, which makes its good performance not be maintained in time. However, there are paths, which can be followed to resolve both problems, with the use of low-dimensionality perovskites. In these structures, it becomes relatively easy…
Professor Juarez L. F. Da Silva (IQSC-USP), leading researcher of CINE in the Materials and Chemistry Computing Science program, is one of the 100,000 most prominent scientists in the world with respect to the impact of his publications and citations, according to ranking published in October of this year in the periodical Plos Biology (https://doi.org/10.1371/journal.pbio.3000918). He is part both of the list which assesses this impact during his career (more…
No ano de 2020, duas mulheres foram agraciadas com o Prêmio Nobel de Química e uma com o Prêmio Nobel de Física. O que mudou na ciência desde a criação desse prêmio? Como podemos alcançar uma maior igualdade de gênero em STEM (Ciência, Tecnologia, Engenharia e Matemática)? Quais foram e ainda são os desafios percorridos pelas mulheres para atingir posições de destaque e liderança num mundo particularmente masculino, onde muitas…
CINE’s management public thanks professor Rubens Maciel Filho (UNICAMP) for the work performed between 2018 and 2020 as director of the Center. The professor continues to act at CINE as leading researcher of the Advanced Energy Storage division/program.
