Bioinduced Room‐Temperature Methanol Reforming [PDF]

Angewandte Chemie International Edition, 2015
AbstractImitating nature′s approach in nucleophile‐activated formaldehyde dehydrogenation, air‐stable ruthenium complexes proved to be exquisite catalysts for the dehydrogenation of formaldehyde hydrate as well as for the transfer hydrogenation to unsaturated organic substrates at loadings as low as 0.5 mol %.

Noiseless single-photon isolator at room temperature

Communications Physics, 2023
Nonreciprocal devices, such as isolators, are of great importance for optical communication and optical information processing. To bypass the limitation of a strong magnetic field imposed by the traditional Faraday magneto-optic effect, many alternative ...

Room Temperature Organic Superconductor? [PDF]

, 2000
The electron--phonon coupling in fullerene C28 has been calculated from first principles. The value of the associated coupling constant lambda/N(0) is found to be a factor three larger than that associated with C60. Assuming similar values of the density

Room-temperature catalyst-free methane chlorination

Cell Reports Physical Science, 2021
Summary: The chlorination of methane presents a route for the upgrading of natural gas to value-added products. However, due to the low reactivity of methane, existing chlorination processes require the use of elevated temperatures and catalysts.
