Towards next-gen functional materials: direct observation of electron transfer in solids      (via sciencedaily.com)     Original source 

Nanoscale electron transfer (ET) in solids is fundamental to the development of multifunctional materials. However, ET in solids is not yet clearly understood. Now, researchers achieved a direct observation of solid-state ET through X-ray crystal analysis by fabricating a novel double-walled non-covalent crystalline nanotube, which can absorb electron donor molecules and maintain its crystalline structure during ET. This innovative approach can lead to the design of novel functional materials soon.

Shining a light on molecules: L-shaped metamaterials can control light direction      (via sciencedaily.com)     Original source 

Polarized light waves spin clockwise or counterclockwise as they travel, with one direction behaving differently than the other as it interacts with molecules. This directionality, called chirality or handedness, could provide a way to identify and sort specific molecules for use in biomedicine applications, but researchers have had limited control over the direction of the waves -- until now.

Transition-metal-free zeolite catalyst for direct conversion of methane to methanol      (via sciencedaily.com)     Original source 

Direct oxidation of methane to methanol is dominated by transition- or noble-metal-based catalysts, thus making the reaction quite expensive. To make the process efficient and cost-effective, researchers developed a transition-metal-free aluminosilicate ferrierite zeolite catalyst that can produce methanol by using methane and nitrous oxide as starting materials. The new catalyst ensures excellent methanol production efficiency, one of the highest recorded rates in the literature thus far.
