A new paper presents the design of a needle-plate dielectric barrier discharge DBD ion source based on 3D printing for high field asymmetric-waveform ion-mobility spectrometry (FAIMS).

AI-powered tools are enhancing precision, efficiency, and decision-making in biopharmaceutical development. Recently, Jared Auclair and Anurag Rathore explored AI's evolving role in biopharmaceuticals in detail.

A study conducted by the Agriculture Research Centre of Giza, Egypt, and Jilin Agricultural University in China, evaluated the efficacy of stinging nettle extract, nettle smoke, and formic acid in the controlling of Varroa mites, a major threat to honeybee colonies, with a focus on mite infestation reduction, honeybee mortality, and biochemical responses. Gas chromatography–mass spectrometry (GC–MS) was used to identify key bioactive compounds in the stinging nettle extract.

Mass spectrometry (MS) can be effective in identifying unknown compounds, though this can be complicated if spectra is outside of known databases. Researchers aimed to test MS databases using electron–ionization (EI)–MS.
