Machine learning model provides quick method for determining the composition of solid chemical mixtures using only photographs of the sample.

Researchers at Kanazawa University report in ACS Nano how ultrathin layers of tin disulfide can be used to accelerate the chemical reduction of carbon dioxide — a finding that is highly relevant for our quest towards a carbon-neutral society.

A research group at Osaka Metropolitan University has succeeded in significantly reducing the measurement time of a glass standard sample by applying Bayesian estimation to X-ray fluorescence analysis. The ability to perform rapid non-contact elemental analysis in a nondestructive manner could lead to the widespread use of this technique in many fields, including the analysis of moving industrial products and waste materials while being carried on conveyor belts.

Researchers at Kanazawa University report in Science Advances a new method for distinguishing between enantiomers, molecules that are mirror images of each other. The procedure, relevant for the pharmaceutical industry, involves the chemical reaction of target enantiomers with color indicator compounds consisting of one-handed helical polymers, leading to solutions showing different colors in specific solvents between the enantiomers.
