Concentration-Dependent Transition in the Rate-Determining Step of Hydrogen Evolution Driven by Pyridinium-Tethered Mononuclear and Dinuclear Platinum Photocatalysts

Abstract Previous studies on the hydrogen evolution reaction (HER) catalyzed by Pt(II)-based molecular catalysts have often demonstrated a second-order dependence of the HER rate on the catalyst concentration, suggesting the importance of stabilizing dinuclear platinum intermedia...

Garlic processing for bioactive transformation and recovery: aging, emerging technologies, extraction, isolation, and functional applications

The health-promoting potential of garlic stems largely from organosulfur compounds (OSCs), phenolics, and flavonoids that drive its antioxidant, anti-inflammatory, and antimicrobial activities. However, key bioactive precursors such as alliin and allicin are chemically unstable,...
