Multipoint Coordinative Capture of Olefinic Substrates Utilizing Metal‐Carbon Bonds by Macrocyclic Complex

open access: yesAngewandte Chemie International Edition, Accepted Article.
Terpenoids and unsaturated fatty acids containing C=C double bonds are biologically and synthetically important compounds. The transformation of these substrates catalyzed by proteins relies on precise molecular capture. However, achieving precise molecular recognition of C=C double bonds using synthetically designed hosts remains a significant ...

Highly Crystalline and Oriented Thin Films of Fully Conjugated 3D‐Covalent Organic Frameworks

open access: yesAngewandte Chemie International Edition, Accepted Article.
Fully conjugated three‐dimensional covalent organic frameworks (COFs) are a newly emerged class of materials that expands reticular chemistry to extended electron delocalization for optoelectronic applications. To overcome the limitations of sp3‐connected 3D frameworks, the pseudo‐tetrahedral motif cyclooctatetrathiophene (COTh) has gained attention ...

Finite Larmor radius influence on MHD solitary waves [PDF]

open access: yesNonlinear Processes in Geophysics, 2009
MHD solitons are studied in a model where the usual Hall-MHD model is extended to include the finite Larmor radius (FLR) corrections to the pressure tensor. The resulting 4-dimensional set of differential equations is treated numerically.

On the Post‐Curing Thermal Treatment of Silicone Rubbers: A Study on Electrical Performance

open access: yesJournal of Applied Polymer Science, EarlyView.
ABSTRACT Silicone rubbers, particularly poly(dimethylsiloxane) (PDMS), are popular across various industrial applications; however, notable issues arise from volatile cyclic siloxanes and their tendency to compromise performance. This study investigates the electrical performance (DC conductivity, dielectric spectroscopy, DC breakdown) of two ...
