CINE computational study selects two-dimensional materials for solar cells

A team from CINE used computational tools to screen two-dimensional materials from the dichalcogenated transition metals (TMDs) family, identifying the best candidates for use in high-performance solar cells. Among 72 materials initially evaluated, only three met all the conditions for this application. Completely carried out through computer simulations, the study made feasible a work that would require much greater resources and time if done experimentally through synthesis and characterization of […]

CINE team performs the first in operando characterization by DRX of a lithium-oxygen battery with redox mediators

The technology of lithium-oxygen batteries (Li-O2) may bring a significant increase in energetic density (quantity of energy stored by weight of battery) comparing to the devices that, today, are in the market, such as ion and lithium batteries. However, several limitations of this technology still need to be overcome to make their commercial use viable. For this, it is necessary to better understand the reactions that occur during the charge […]

CINE researcher participates in international scientific consortium dedicated to generate reports on the performance of emerging solar cells

The integration of solar cells to façades, windows, clothing and accessories has started to become reality thanks to the so-called emerging photovoltaic technologies, which are characterized for offering flexible and transparent devices. These devices, which cover organic, dye-sensitized and perovskites solar cells, have generated much interest, not only from companies and consumers, but also from researchers who are working to overcome the limitations of those technologies. For these research groups, […]

CINE’s computational study contributes to the development of more selective catalysts for the transformation of CO2 into raw materials for the industry.

Known by the acronym CCUS, the concept of “Carbon Capture, Utilization and Storage” covers the processes and technologies which aim at reducing the concentration of carbon dioxide (CO2) in the atmosphere through the safe storage of that greenhouse gas or its transformation into other molecules which can be used as raw material for the fabrication of fuels and other products. In a recently published paper, CINE researchers present a contribution to this […]

Collaboration of CINE with a group from UK generates a review on photoelectrochemical analysis techniques.

A review paper on photoelectrochemical methods of analysis and detection is the most recent result of the collaboration between the research group of professor Lucia Helena Mascaro (UFSCar, Brazil), a CINE researcher, and the group of professor Frank Marken (University of Bath, United Kingdom). Published in the February issue of the journal TrAC Trends in Analytical Chemistry (impact factor 9.8), the article was written during the research internship that the PhD […]

CINE’s collaboration with a German research center makes possible research on membranes for separation of CO2.

A scientific collaboration between researchers from CINE and from an important research center in Germany made possible the development of production techniques of porous membranes with high efficiency for separation of carbon dioxide (CO2). The research is part of the efforts made in CINE’s Division “Methane to Products” to convert methane (an abundant gas on planet Earth) into higher added value fuels and chemical compounds. These membranes separate the CO2 […]

Patent: CINE team develops device to study metal-air batteries

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 […]

CINE research contributes to the generation of electricity from ethanol using fuel cells.

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, […]
