One‐Pot Synthesis of d‐Amino Acids Using a Soluble and Immobilized LAAO–CAT–d‐Transaminase Cascade

ChemCatChem, Volume 18, Issue 5, 13 March 2026.
Production of d‐amino acids with the HcLAAO4– d‐TAEi –CAT enzyme cascade. l‑amino acids are oxidatively deaminated by HcLAAO4 consuming molecular oxygen to the corresponding α‑keto acids. Subsequently, d‐TAEi catalyzes the reductive amination of the keto acids using d‑alanine as co‐substrate to produce the d‑amino acids and pyruvate. Catalase (CAT) was

Prediction of Thermal Modulated Comprehensive Two‐Dimensional Gas Chromatographic Separation Using a Modular, Graph‐Based Simulation Platform

Journal of Separation Science, Volume 49, Issue 1, January 2026.
ABSTRACT Comprehensive two‐dimensional gas chromatography (GC×GC) offers exceptional separation performance, but method development remains time‐consuming and sensitive to numerous system parameters. In this study, we present a modular simulation framework for GC×GC systems with thermal modulation, implemented in the open‐source Julia package ...

Formulation and Delivery Systems of Cocaine and Methamphetamine Scent Mimics

International Journal of Analytical Chemistry, Volume 2026, Issue 1, 2026.
Narcotic scent mimics, which are chemicals that emit a perceivable scent similar to that of the illicit drug but do not possess the health and addiction risks of the drug, have applications ranging from canine training in law enforcement agencies to antinarcotic public education.

A Potassium Base‐Promoted Intramolecular Enolate–Olefin Metathesis

Chemistry – A European Journal, Volume 31, Issue 55, October 1, 2025.
A novel olefin metathesis, the enolate‐olefin metathesis reaction, in which two double bonds recombine via a four‐membered carbocyclic intermediate (NOT metallacyclobutane intermediate), is developed. The methodology is a transition‐metal‐free, base‐promoted enolate–olefin metathesis involving [2 + 2] / retro‐[2 + 2] cycloaddition sequences of 2‐acyl‐2′
