Electrochemical conversion of carbon dioxide (CO2) into fuels and value-added feedstocks, ideally if powered by renewable electricity, provides a route to reduce greenhouse gas emissions and simultaneously close the carbon loop. At present, the rational design and controllable synthesis of more efficient catalysts, combined with the understanding of the catalytic mechanism, in order to achieve

These gases are attractive clean energy alternatives to carbon dioxide-producing fossil fuels.

The researchers say their results, using an atomically thin material, hexagonal boron nitride, constitute a significant step forward in understanding light-matter interactions of

CAMBRIDGE, MA — MIT engineers have developed a way to closely track how plants respond to stresses such as injury, infection, and light damage, using sensors made of carbon nanotubes. These sensors can be embedded in plant leaves, where they report on hydrogen peroxide signaling waves. Plants use hydrogen peroxide to communicate within their leaves,

In the last decade, perovskites – a diverse range of materials with a specific crystal structure – have emerged as promising alternatives to silicon solar cells, as they are cheaper and greener to manufacture, while achieving a comparable level of efficiency. However, perovskites still show significant performance losses and instabilities, particularly in the specific materials

The rapid progression of technology has led to a huge increase in energy usage to process the massive troves of data generated by devices. But researchers in the Cockrell School of Engineering at The University of Texas at Austin have found a way to make the new generation of smart computers more energy efficient. Traditionally,

Irvine, Calif., April 13, 2020 – Researchers at the University of California, Irvine and other institutions have architecturally designed plate-nanolattices – nanometer-sized carbon structures – that are stronger than diamonds as a ratio of strength to density. In a recent study in Nature Communications, the scientists report success in conceptualizing and fabricating the material, which
