We performed coarse-grained molecular dynamics simulations of swelling and degradation of copolymer films confined within polymer networks with different values of shear modulus.
Herein, we describe an organic photoredox system for direct arene C–H radiofluorination, using a peroxide oxidizing agent and LEDs as the light source.
Here, we take advantage of ambient oxygen present in river water to quantify one of the more harmful PFAS molecules, perfluorooctanesulfonate (PFOS), from 0 to 0.5 nM on a MIP-modified carbon substrate.
Here, using first-principles calculations, we find that adsorption of water to a defective NiO(111) surface can result in intraband gap surface electronic states that are associated with hydroxyl and oxygen moieties adjacent to Ni vacancies.
Using the insect pathogen Pseudomonas entomophila L48 as a model, we demonstrated that pvf-encoded biosynthetic enzymes produce PVF autoinducers that regulate the expression of pvf genes and a gene encoding the toxin monalysin via quorum sensing.
In this Letter, we use nonlinear photocurrent spectroscopy to selectively target charge transport processes within devices based on layered perovskite quantum wells. The photocurrent induced by a pair of laser pulses is directly measured in this “action” spectroscopy to remove ambiguities in signal interpretation.
Here, we studied the impact of aggregation on charge generation using transient absorption spectroscopy, neutron scattering, and atomic force microscopy.
This review focuses on applications of ALD in DSPECs for the preparation of solar fuels based on modified semiconductor surfaces. In this area, ALD has been used to prepare core/shell structures that modify surface-interfacial electron transfer, to prepare structures that stabilize surface-bound chromophores and catalysts, and for the preparation of overlayer structures that stabilize electrodes for water oxidation and photocathodes for H-2 or CO2 reduction.
The kinetics of grafting-through polymerization of PDMS11MA macromonomers was studied to establish correlations between reversible first-order kinetic trends and network mechanical properties. By varying the reaction conditions, including the initial monomer concentration, targeted degree of polymerization, and solvent, the syntheses of macroinitiators and chain extensions were optimized with improved chain-end fidelity while maintaining a high yield and provided elastomers with consistent desired mechanical properties.
Hemilabile ligands are found in many leading organometallic catalysts, but it can be challenging to tune the degree of hemilability in a particular catalyst. This work explores the impact of cation-tunable hemilability on the speciation of iridium(III) pincer-crown ether catalysts during high-activity olefin isomerization.
A general method for the synthesis of secondary homoallylic alcohols containing α-quaternary carbon stereogenic centers in high diastereo- and enantioselectivity (up to >20:1 dr and >99:1 er) is disclosed.
