Electrocatalytic Dehydrogenative Lactonization of Benzylic Alcohols: A Sustainable Access to Phthalides via N‐hydroxyphthalimide Mediation

Advanced Synthesis &Catalysis, EarlyView.
A mild, scalable electrocatalytic method for direct lactonization of benzylic alcohols to phthalides using N‐hydroxyphthalimide as a redox mediator is reported. This metal‐free process proceeds via a phthalimide‐N‐oxyl‐mediated hydrogen atom transfer mechanism, shows broad scope with good to excellent yields, and enables late‐stage functionalizations ...

Formulation and evaluation of sustained release matrix tablet of rabeprazole using wet granulation technique

Journal of Pharmacy and Bioallied Sciences, 2014
Introduction: Rabeprazole, a member of substituted benzimidazoles, inhibits the final step in gastric acid secretions. This drug claims to cause fastest acid separation (due to higher pKa), and more rapidly converts to the active species to aid gastric ...

Fluorescent Chitosan Hydrogels Based on Biomass‐Derived Carbon Dots for Toxic Aromatic Detection

Advanced Sustainable Systems, EarlyView.
Carbon dots made from food waste via a microwave–ultrasound method show strong, pH‐stable fluorescence. Thermal pretreatment enhances their optical properties. Incorporated into chitosan hydrogels, these dots form reusable sensors for detecting aromatic pollutants in water.

Novel Manufacturing of Cellulose‐Based Membranes for Energy Storage Devices: Toward a PFAS Free Future

Advanced Sustainable Systems, EarlyView.
This work presents a novel, scalable method for manufacturing PFAS‐free cellulose‐based membranes for energy storage devices. By coating kraft paper with cellulose nanofibrils and optimizing barrier and ionic conductivity properties, membranes are achieved that prevent redox molecule crossover while maintaining performance.
