A section of San Marin High School was evacuated after workers discovered a bottle of explosive acid that had been sitting for decades in a science lab. The chemical, picric acid, becomes increasingly ...

Our body odor may not win us friends on a crowded city bus, but the lineup of volatile compounds wafting from our skin—including amines, carboxylic acids, ketones, and sulfides—is a major draw for ...

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 ...

THE separation of several non-volatile carboxylic acids by paper chromatography has been described by Lugg and Overell 1,2. These workers found that it was impossible to carry out the separation with ...

The plant, which operated until 2015 before being placed on care and maintenance, would allow Marimaca to reduce its exposure to volatile acid markets, a key input cost for its copper operations.

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 ...
