Using Brewery Waste and Green Deep Eutectic Solvent for High Performance Sustainable Supercapacitors

open access: yesBattery Energy, Volume 5, Issue 3, May 2026.
Combination of biomass waste (spent grain) based porous carbon and hybrid DES electrolyte made of betaine:urea [1:2] with the addition of DI water and sodium perchlorate salt leads to supercapacitors that operates at higher operating voltage window upto 2.6 V with excellent energy density and cyclic stability.

Electrochemical Skeletal Editing via Manganese‐Catalyzed Nitrogen Atom Insertion Scalable by Electroflow

open access: yesChemistryEurope, Volume 4, Issue 5, May 2026.
Direct nitrogen atom insertion for skeletal editing tends to rely on superstoichiometric amounts of chemical oxidants. Herein, we report on a manganaelectro‐catalyzed nitrogen atom insertion into indenes with broad scope to access isoquinolines. Additionally, the reaction is easily scalable via electroflow.
