A High‐Performance Oxidized Graphene for Dendrite‐Free Anodes and Kinetically Enhanced Cathodes of Aqueous Zn‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Oxidized graphene rich in carboxylic acid groups obtained via a simple electrochemical exfoliation route is shown to tackle the main challenges of aqueous Zn‐ion batteries (AZIBs), specifically short Zn anode cycle life and sluggish cathode reaction kinetics.

Cobalt Single‐Atom Sites Engineered in Poly(Heptazine Imide) Photocathodes as Benchmark for Alkaline Hydrogen Evolution: A Comparative Transition Metal Study

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Cobalt single‐atoms in poly(heptazine imide) photocathodes maximize active‐site availability and outperform Fe, Cu, and Na in alkaline hydrogen evolution. Atomic precision (not bulk loading) proves predominance, establishing a design principle for the next generation of solar fuel devices.

Synthesis of Cysteine–Fluorophore Conjugates by Visible‐Light‐Promoted Thiol–Ene Coupling Using Organic Photocatalysts

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Cysteine–fluorophore conjugates were efficiently prepared through a visible‐light‐driven thiol–ene approach employing solely organic photocatalysts. The reaction proceeds under mild, metal‐free conditions. The fluorophore scope includes mono‐ and dialkene‐functionalized naphthalene, naphthalimide, and aromatic diimide derivatives.
