Metathesis‐Sourced Epoxides in Ring‐Opening Copolymerization: Selective Access to Degradable Polythioesters

Macromolecular Rapid Communications, EarlyView.
Metathesis‐derived cyclopentene epoxides enable strictly alternating, scrambling‐free ring‐opening copolymerization with phthalic thioanhydride, yielding well‐defined polythioesters with molecular weights up to ∼38 kg/mol. Their performance extends to oxygen‐based anhydrides and selective terpolymerizations. Direct comparisons with all‐oxygen analogues

Insights into the function of silver as an oxidation catalyst by ab initio, atomistic thermodynamics [PDF]

, 2003
To help understand the high activity of silver as an oxidation catalyst, e.g., for the oxidation of ethylene to epoxide and the dehydrogenation of methanol to formaldehyde, the interaction and stability of oxygen species at the Ag(111) surface has been ...

Pure Gaussian Apodisation Reduces Integral Crosstalk Sensitivity in Quantitative NMR

Magnetic Resonance in Chemistry, EarlyView.
Exponential apodisation redistributes peak area away from its centre, which increases crosstalk with neighbouring peaks and reduces integral trueness when integrating between defined regions. A pure Gaussian apodisation limits wing growth: Crosstalk between peaks is not worsened, and trueness is conserved during integration.

Valorization of Poplar Wood Wastes Into 3D‐Printed Soya Oil‐Based Composites by Vat Photopolymerization for Interior Design

Journal of Polymer Science, EarlyView.
Bio‐based polymer composites were 3D printed by LCD vat photopolymerization using acrylate epoxidized soybean oil as the monomer and isobornyl methacrylate as the reactive diluent. Two different poplar powders derived from plywood processing waste were incorporated within the photocurable formulations.

Epoxides and Soluble Epoxide Hydrolase in Cardiovascular Physiology [PDF]

Physiological Reviews, 2012
Epoxyeicosatrienoic acids (EETs) are arachidonic acid metabolites that importantly contribute to vascular and cardiac physiology. The contribution of EETs to vascular and cardiac function is further influenced by soluble epoxide hydrolase (sEH) that degrades EETs to diols. Vascular actions of EETs include dilation and angiogenesis.
