Four-electron Reduction and Functionalization of N2 by a Uranium(III) Bridging Nitride

CHIMIA, 2018
N2 is a cheap and widely available but very unreactive molecule. Notably, the only industrial process for the conversion of dinitrogen is the Haber-Bosch process to form ammonia, but under very harsh conditions (high temperature and pressure ...

Deep Reactive-Ion Etching Development With the Bosch Process [PDF]

, 2022
The Bosch process is a type of deep reactive-ion etching (DRIE) of silicon. It is a type of plasma etching, or dry etching, that uses physical and chemical processes to etch the surface of a silicon sample.

Atomic‐Scale Understanding of Selectivity Control in Nitrate Reduction on Cu(100) Under Acidic and Alkaline Conditions

Angewandte Chemie, Volume 138, Issue 23, 1 June 2026.
A combination of ab initio molecular dynamics simulations and density functional theory calculations clarifies the pH‐dependent origin of the selectivity of nitrate reduction on Cu(100). ABSTRACT We investigate the nitrate reduction reaction (NO3 RR) on the Cu(100) surface using grand‐canonical density functional theory (GC‐DFT) under constant ...

Constructing Cu/Cu2O Heterogeneous Interface for Efficient Urea Electrosynthesis

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
In this study, a Cu/Cu2O heterogeneous interface with dual active sites is prepared for electrocatalytic CO2 and NO3− coupling to urea. The catalyst shows high yield rates of 1156.63 mmol g−1 h−1 and FE of 29.67% at −1.0 V (vs RHE), which is significantly higher than Cu and Cu2O, highlighting the advantages of heterogeneous interface synergistic ...

Antioxidants in Plant‐Based Food Matrices: From Structure–Activity and Degradation Kinetics to Formulation Design

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 4, July 2026.
ABSTRACT Plant‐based antioxidants are widely incorporated into foods to retard oxidative deterioration and to deliver health‐related benefits. Yet, their in‐product and in vivo performance frequently diverges from predictions based on solution‐phase chemical assays, because matrix interactions, processing history, and host metabolism reshape both ...

Synthesis and Evaluation of Novel Ruthenium on Dysprosium‐Praseodymium Oxide Catalysts for Ammonia Synthesis and Decomposition in the Hydrogen Energy Vector Transition

ChemSusChem, Volume 19, Issue 11, 15 June 2026.
Adding dysprosium to a praseodymium oxide support led to an increase in ammonia decomposition activity, ammonia synthesis activity, improved catalyst stability, and improved electron transfer to the ruthenium. Currently, there is a push to reduce reliance on hydrocarbon fuels for energy storage by using hydrogen carriers.
