Visualizing and Quantifying Impact with Mechanochromic Sensing Paints Based on Self‐Assembled Polydiacetylene‐Silk Core‐Shell Vesicles

Advanced Science, EarlyView.
Tracking physical impacts is important in many fields. Self‐assembled microparticles made from polydiacetylene and silk fibroin that change color from blue to red when hit can provide an alternative approach to traditional mechanical transducers, quantitatively visualizing impact with responses ranging from <100 to 770 N.

Radium Speciation in Simulated Digestive Biofluids: Insights from Electrospray Ionization Mass Spectrometry and Thermodynamic Modeling

Analysis &Sensing, EarlyView.
Electrospray ionization mass spectrometry (ESI‐MS) combined with thermodynamic modeling provides the first direct characterization of radium speciation in synthetic gastrointestinal biofluids. Free Ra2+ ions predominate with minimal protein binding and negligible EDTA complexation. Crown ethers enable effective Ra complexation.
