Colloidal Heterostructures Enable Interfacial Transport of Immiscible Molecules in Printable Organohydrogels

open access: yesAdvanced Materials, EarlyView.
Multiphase printable organohydrogels with tunable microstructures are developed to control molecular transport pathways for immiscible cargo. The tortuosity and domain size of the colloidal phases are tuned by adjusting temperature and shear during processing, which enables the tailoring of diffusion kinetics due to different transport pathways.

Mechanism of H_2 Evolution from a Photogenerated Hydridocobaloxime [PDF]

open access: yes, 2010
Proton transfer from the triplet excited state of brominated naphthol to a difluoroboryl bridged Co^I-diglyoxime complex, forming Co^(III)H, was monitored via transient absorption. The second-order rate constant for Co^(III)H formation is in the range (3.

A Biochar‐Based Composite Hydrogel Microenvironment for Enhanced Biocatalysis

open access: yesAdvanced Materials, EarlyView.
This work presents the synthesis of a polyacrylamide hydrogel wherein biomass‐derived biochar is co‐encapsulated with the enzyme horseradish peroxidase (HRP). The resulting composite hydrogel possesses balanced electron‐rich and electron‐deficient domains, creating an optimal microenvironment that concentrates both hydrogen peroxide and phenol ...

Neutral‐pH Electropolymerization of Aniline on Hierarchically Porous Laser‐Induced Graphene Electrodes for Dual Biosensing

open access: yesAdvanced Materials Technologies, EarlyView.
Neutral‐pH electropolymerization of aniline on laser‐induced graphene (LIG) produces stable, brush‐like polyaniline coatings without requiring acidic conditions. The resulting PANI–LIG electrodes exhibit enhanced electroactive surface area, efficient charge transfer, and dual sensing capability for β‐blockers and pH, providing a scalable platform ...

Chiral Potassium Brønsted Base‐Catalyzed Stereoselective Synthesis of 1,3‐Diols via a Tandem Allylic Isomerization/Asymmetric Aldol–Tishchenko Reaction

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Chiral potassium base catalysts featuring 1,1´‐bi‐2‐naphthol‐derived chiral crown ethers as ligands promote a tandem allylic isomerization/asymmetric aldol‐Tishchenko reaction of allylic alcohols and aldehydes. This method provides enantioenriched 1,3‐diols with excellent diastereoselectivity and high enantioselectivity, thereby expanding the synthetic

Sterol 3β-glucosyltransferase biocatalysts with a range of selectivities, including selectivity for testosterone [PDF]

open access: yes, 2013
The main objectives of this work were to characterise a range of purified recombinant sterol 3β-glucosyltransferases and show that rational sampling of the diversity that exists within sterol 3β-glucosyltransferase sequence space can result in a range of

Gαi1/3 Is a Novel Regulatory Target for RANKL Signal Transduction and Osteoporosis

open access: yesAdvanced Science, EarlyView.
ABSTRACT Osteoporosis, characterized by progressive bone loss and increased fracture risk, is a growing concern as the population ages. Current treatments, though advanced, remain limited, underscoring the necessity for novel therapeutic targets. Recent studies have shown that the immune system plays a key role in osteoporosis, with osteoclasts driving

Equilibrium Adsorption of Single Component and Binary Mixtures of Aromatic Compounds onto a Polyfunctional Hypercrosslinked Polymeric Adsorbent

open access: yesAdsorption Science & Technology, 2004
A polyfunctional hypercrosslinked polymeric adsorbent, LA-8, was synthesized and characterized. It was first used to investigate the adsorption properties of 1-amino-2-naphthol-4-sulphonic acid (1,2,4-acid), including the corresponding adsorption ...

An All‐in‐One Lignin‐Based Artificial Thylakoid Nanovesicle Via In‐Situ Confined Growth Strategy for High‐Efficient and Selectivity CO2 Photoreduction

open access: yesCarbon Energy, EarlyView.
The low light/CO2 capture and slow dynamic transfer of photogenerated electrons hamper photocatalysts’ high activity and selectivity. Inspired by the chloroplast's photosynthesis mechanism, an all‐in‐one lignin‐based artificial thylakoid nanovesicle (AiO‐L‐ATN) is constructed using a confined growth strategy of lignin molecules. The performance of such
