Efficient Synthesis of Dipyrazino[2,3-f; 2'3'-h]quinoxaline

open access: yesCHIMIA, 1987
The condensation of benzenehexamine (2) with the masked forms 3a or 3b of glyoxal leads to the title compound (4) in good yields; aqueous glyoxal is highly unsatisfactory.

Glyoxylic‐Acetal‐Based Gel‐Polymer Electrolytes for Lithium‐Ion Batteries

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
A safe electrolyte based on tetraethoxyglyoxal (LE) is combined with a methacrylate polymer matrix. The resulting gel‐polymer electrolyte (GPE) exhibits an increased flash point, suitable ionic conductivity, and a stable performance in lithium‐ion battery cells.

Vegetation Dynamics and Atmospheric Glyoxal in Houston, Texas (2018–2022)

open access: yesAtmosphere
Twenty years of MODIS satellite data (2002–2022), TROPOMI glyoxal observations (2018–2022), and ground-based isoprene measurements were used to examine vegetation greenness (NDVI) and atmospheric glyoxal over Houston, Texas. Biogenically produced glyoxal

The Impact of Glycation on Protein Digestibility

open access: yesChemFoodChem, EarlyView.
Schematic overview of how protein glycation affects digestibility and downstream nutritional consequences. Glycation‐derived structural modifications reduce protease accessibility, leading to limited hydrolysis and altered peptide generation. These changes decrease amino acid bioavailability and may subsequently contribute to microbiome alterations ...
