Nanobubbles (NBs) are tiny gas cavities with diameters around 200 nm that remain stable in solution due to their unique properties, including low buoyancy and negative surface charges. Ammonium ...

Mass spectrometry generates vast amounts of data in chemistry labs. Here, authors developed a machine learning-driven search engine that analyzes archived data to discover chemical reactions ...

“Our laser ablation ionization mass spectrometer ... a miniature laser-powered mass spectrometer, which can analyze the chemical composition of a sample in detail as fine as a micrometer.

In 1899, German physicists Elster and Geitel were among the first to study air ionization, identifying how ions are formed in the atmosphere. Later research, particularly in the 1930s and 1950s ...
