Inline small-angle X-ray scattering-coupled chromatography under extreme hydrostatic pressure.

As continuing discoveries highlight the surprising abundance and resilience of deep ocean and subsurface microbial life, the effects of extreme hydrostatic pressure on biological structure and function have attracted renewed interest. Biological small-angle X-ray scattering (BioSAXS) is a widely used method of obtaining structural information from biomolecules in solution under a wide range of solution conditions. Due to its ability to reduce radiation damage, remove aggregates, and separate monodisperse components from complex mixtures, size-exclusion chromatography-coupled SAXS (SEC-SAXS) is now the dominant form of BioSAXS at many synchrotron beamlines.

Sign Language Incorporation in Chemistry Education (SLICE): Building a Lexicon to Support the Understanding of Organic Chemistry.

Historically, deaf and hard-of-hearing students (D/HH) who solely rely on an interpreter during organic chemistry lecture courses at the Rochester Institute of Technology consistently performed below the average in the class. A barrier attributed to this D/HH student performance is the lack of standardized methods in sign language to effectively communicate the organic chemistry terminology. As such, our group worked to address this challenge through a deliberate effort to develop a lexicon of insightful signs/classifiers that convey organic chemistry vocabulary as well as descriptive expansions to demonstrate challenging concepts.

Qualitative Analysis of E-Liquid Emissions as a Function of Flavor Additives Using Two Aerosol Capture Methods.

This work investigates emissions sampling methods employed for qualitative identification of compounds in e-liquids and their resultant aerosols to assess what capture methods may be sufficient to identify harmful and potentially harmful constituents present. Three popular e-liquid flavors (cinnamon, mango, vanilla) were analyzed using qualitative gas chromatography-mass spectrometry (GC-MS) in the un-puffed state. Each liquid was also machine-puffed under realistic-use flow rate conditions and emissions were captured using two techniques: filter pads and methanol impingers.
