Headline: Novel titanium dioxide catalyst support for electrocatalytic carbon dioxide reduction
■ Release Date: 2023.9.5
■ Published by: Tokyo University of Science
■ Keywords: titanium dioxide, catalyst, electrode
■ Abstract:
Carbon dioxide can be electrocatalytically reduced to useful resources using conventional catalysts such as gold or lead supported on conductive carbon. However, the high pH environment near electrodes often degrades the catalyst support, rendering them ineffective. Now, researchers have developed novel in-liquid plasma-treated titanium dioxide electrode decorated with silver nanoparticles as an alternate catalyst support, facilitating enhanced conversion of carbon dioxide to useful products, such as syngas, a clean alternative to fossil fuels.
Headline: Pioneering beyond-silicon technology via residue-free field effect transistors
■ Release Date: 2023.9.5
■ Published by: Institute for Basic Science
■ Keywords: bismuth, semimetal, silicon
■ Abstract:
Beyond-silicon technology demands ultra-high-performance field-effect transistors (FETs). Transition metal dichalcogenides (TMDs) provide an ideal material platform, but the device performances such as contact resistance, on/off ratio, and mobility are often limited by the presence of interfacial residues caused by transfer procedures. We show an ideal residue-free transfer approach using polypropylene carbonate (PPC) with a negligible residue for monolayer MoS2. By incorporating bismuth semimetal contact with atomically clean monolayer MoS2-FET on h-BN substrate, we obtain an ultralow Ohmic contact resistance approaching the quantum limit and a record-high on/off ratio of ~1011 at 15 K. Such an ultraclean fabrication approach could be the ideal platform for high-performance electrical devices using large-area semiconducting TMDs.
Headline: Efficient and mild: Recycling of used lithium-ion batteries
■ Release Date: 2023.9.5
■ Published by: Wiley
■ Keywords: recycling, lithium-ion, battery
■ Abstract:
Lithium-ion batteries (LIBs) provide our portable devices like tablets and mobiles -- and increasingly also vehicles -- with power. As the share of volatile renewable energy needing electricity storage increases, more and more LIBs are needed, lithium prices rise, resources dwindle, and the amount of depleted batteries that contain toxic substances increases. Researchers introduce a novel approach for the recovery of lithium from used LIBs.

Headline: Extending the playing field for organosulfurs: a new way to synthesize sulfinate esters
■ Release Date: 2023.9.7
■ Published by: Tokyo University of Science
■ Keywords: sulfinate esters, thioesters, organosulfur
■ Abstract:
Sulfinate esters, a type of organosulfur compounds, are typically synthesized using thiols. However, these substances are difficult to work with due to their unpleasant smell and oxidizability in air. Now, a research team has found a way to produce sulfinate esters through the direct oxidation of thioesters, which are easily accessible and stable. Their findings will help expand the field of organosulfur chemistry and hopefully lead to new applications in pharmaceuticals.

Headline: New study reveals the power of railroads to buffer coal plants from a carbon emissions tax
■ Release Date: 2023.9.7
■ Published by: University of Maryland
■ Keywords: coal, carbon, energy
■ Abstract:
A new study suggests that railroads are likely to cut transportation prices to prop up coal-fired plants if U.S. climate policies further disadvantage coal in favor of less carbon-intensive energy sources.
