A METHOD for the identification of volatile fatty acids by means of paper chromatography was reported by Hiscox and Berridge 1. In this method the acid was applied as the ethylamine salt to the paper, ...

A new study shows that aerosols in indoor air can vary in acidity. This acidity determines how long viruses remain infectious in the air -- with profound implications for virus transmission and ...

Viruses such as SARS-CoV-2, influenza virus and others travel from person to person essentially by hitchhiking on aerosols. These are finely dispersed particles containing liquid suspended in the air ...
