The Role of Cytochrome P450 AbyV in the Final Stages of Abyssomicin C Biosynthesis

Angewandte Chemie International Edition, Volume 62, Issue 3, January 16, 2023., 2023
The cytochrome P450 enzyme AbyV catalyses a key epoxidation in the final stages of the biosynthesis of the spirotetronate antibiotic abyssomicin C. Combining structural and computational data with a 13C labelling strategy was found to be a powerful approach to interrogate the biotransformation and determine the precise function of the enzyme.

The Contributions of James Moir to Physical Chemistry [PDF]

, 2014
James Moir was a pioneering chemist in the early 1900s who played a leading role in various chemical societies in South Africa. Although he was mainly an organic chemist, he was a very good all-round chemist, whose analytical and organic activities have ...

Heat Conduction Modulation in Incommensurate Twisted Stacking of Transition‐Metal Dichalcogenide

Advanced Functional Materials, EarlyView.
The interlayer thermal conductance in twisted bilayer TMDs is initially investigated experimentally by the thermoreflectance method. The overlap of lattice vibrations within individual layers and the interlayer interactions, as elucidated through both Raman spectroscopy and molecular dynamics simulations, are demonstrated to be critical factors in ...

Fluorine‐Directed Automated Mannoside Assembly

Angewandte Chemie International Edition, Volume 62, Issue 3, January 16, 2023., 2023
Motivated by the importance of fluorination in drug discovery, fluorine‐directed automated glycan assembly (AFGA) is disclosed. This strategy leverages the C(sp3)−F bond at C2 to enable α‐stereocontrolled glycosylation that eliminates the reliance on O‐based directing groups.

Gas phase production of NHD2 in L134N [PDF]

, 2001
We show analytically that large abundances of NH2D and NHD2 can be produced by gas phase chemistry in the interiors of cold dense clouds. The calculated fractionation ratios are in good agreement with the values that have been previously determined in L134N and suggest that triply-deuterated ammonia could be detectable in dark clouds.

Entropic measures of Rydberg-like harmonic states [PDF]

Int. J. Quantum Chem. 117(1) (2017) 48-56, 2016
The Shannon entropy, the desequilibrium and their generalizations (R\'enyi and Tsallis entropies) of the three-dimensional single-particle systems in a spherically-symmetric potential $V(r)$ can be decomposed into angular and radial parts. The radial part depends on the analytical form of the potential, but the angular part does not.

Pushing Radiative Cooling Technology to Real Applications

Advanced Materials, EarlyView.
Radiative cooling controls surface optical properties for solar and thermal radiation, offering solutions for global warming and energy savings. Despite significant advances, key challenges remain: optimizing optical efficiency, maintaining aesthetics, preventing overcooling, enhancing durability, and enabling scalable production.

Reduction of Na+ within a {Mg2Na2} Assembly

Angewandte Chemie International Edition, Volume 62, Issue 3, January 16, 2023., 2023
Treatment of a low oxidation state {Mg2Na2} assembly with basic molecules that are less prone to reduction than the sodium cation itself induces the complete extrusion of the elemental alkali metal. Abstract Ionic compounds containing sodium cations are notable for their stability and resistance to redox reactivity unless highly reducing electrical ...
