Beware the Artifact: Generation of Ellagic Acid and Related Species During Atmospheric Solid Analysis Probe (ASAP) Measurements of Iron Gall Inks and Tannins in the Negative Ionization Mode

Journal of Mass Spectrometry, Volume 61, Issue 4, April 2026.
ABSTRACT A detailed comparative analysis of the results of atmospheric solid analysis probe (ASAP) mass spectrometry of inks, tannins, and gallic acid (GA) in the negative ionization mode was performed. Results obtained for tannin by ASAP have been compared with those obtained with electrospray ionization (ESI).

Ultrafast Electro‐Optical Response of Polymer‐Dispersed Liquid Crystals with Ferroelectric Nematic Liquid Crystal in Light Transmission to Light Scattering Switching

Macromolecular Materials and Engineering, Volume 311, Issue 4, April 2026.
Polymer‐dispersed liquid crystals (PDLCs) are electro‐optical functional materials capable of switching between light‐transmitting and light‐scattering states. We successfully fabricated a PDLC for the first time using ferroelectric nematic liquid crystal (FNLC) with high polar and spontaneous polarization.
