Based on their hypothesis that smelling anxiety chemosignals can, like visual anxiety induction, lead to an increase in odor sensitivity, a joint study between the University of Erlangen-Nuremberg (Erlangen, Germany) and the Fraunhofer Institute for Process Engineering and Packaging (Freising, Germany) combined behavioral experiments, odor profile analysis by a trained panel, and instrumental analysis of odorants (gas chromatography-olfactometry) and volatiles (gas chromatography-mass spectrometry).

3D printing technology has potential in chromatography, but a major challenge is developing materials with both high porosity and robust mechanical properties. Recently, scientists compared the separation performances of eight different 3D printable stationary phases.

Ion mobility spectrometers can detect trace compounds quickly, though they can face various issues with detecting certain peaks. University of Hannover scientists created a new system for resolving hyper-fast gas chromatography (GC) peaks.

Bacteriophages are vital for addressing antibiotic-resistant bacteria, though phage therapies are currently rare. University of Lisbon researchers recently created a new purification workflow to address these concerns.
