Amino acid‐derived Cu(II)‐dithiocarbamates were synthesized as water‐soluble single‐source precursors for low‐temperature hydrothermal decomposition toward covellite (CuS) nanoparticles. Their decomposition followed a reduction‐mediated pathway via Cu(I)‐dithiocarbamate intermediates, with the reduction step being rate‐limiting and readily tunable ...

The chemical structure of Carbon Dots (CDs) is still a mystery despite years of study. Herein, we show how CDs with a higher density of surface‐accessible amines display enhanced (photo)redox performance. Electrochemical and thermodynamic analyses confirmed the feasibility of electron transfer, while mechanistic investigations revealed that the ...

Energetics for Hydrogen Atom Transfer by Ketyl Radicals: Is Thermodynamics on Your Side?
The classic hydrogen atom transfer from the 1900 Ciamician paper and its enthalpic changes illustrate ketyl thermodynamics. ABSTRACT Ketyl radicals play a key role in various reaction mechanisms, where their ability to donate hydrogen atoms governs numerous processes, ranging from photoredox catalysis to biological mechanisms and the synthesis of metal
