Atomic Scale Engineering of Multivalence‐State Palladium Photocatalyst for Transfer Hydrogenation with Water as a Proton Source

Advanced Materials, EarlyView.
Photocatalytic transfer hydrogenation is achieved over a multivalence‐state palladium photocatalyst, in which protons generated from photocatalytic water splitting are added to unsaturated double bonds. The operando light‐induced Electron Paramagnetic Resonance (EPR) spectroscopy confirms the synergistic action between Pd single atoms and nanoparticles,

Breaking the Selectivity Barrier of Single‐Atom Nanozymes Through Out‐of‐Plane Ligand Coordination

Advanced Materials, EarlyView.
Here, Ru SAzyme with out‐of‐plane chlorine ligands is reported as a monofunctional, high‐performance peroxidase‐like nanozyme. Incorporating out‐of‐plane ligand coordination emulates enzyme selectivity and regulates reaction pathways for an identical substrate.

Integrating Visible‐Light Photocatalysis and Enzymes for the Stereoselective Synthesis of Alcohols and Amines

Advanced Synthesis &Catalysis, EarlyView.
The integration between visible‐light photocatalysis and biocatalysis has the potential to greatly improve modern organic synthesis by combining the production of valuable synthetic intermediates under mild photochemical conditions with the high degree of stereoselectivity reached by enzymes. The review collects the recent efforts in the photoenzymatic

Proteomic analysis of Clostridium thermocellum core metabolism: relative protein expression profiles and growth phase-dependent changes in protein expression

BMC Microbiology, 2012
Background Clostridium thermocellum produces H2 and ethanol, as well as CO2, acetate, formate, and lactate, directly from cellulosic biomass. It is therefore an attractive model for biofuel production via consolidated bioprocessing.

Modeling Alcohol Dehydrogenase Catalysis in Deep Eutectic Solvent/Water Mixtures

ChemBioChem, 2019
The use of oxidoreductases (EC1) in non‐conventional reaction media has been increasingly explored. In particular, deep eutectic solvents (DESs) have emerged as a novel class of solvents.

Presbycusis: Pathology, Signal Pathways, and Therapeutic Strategy

Advanced Science, EarlyView.
In ARHL, the stria vascularis, acting as a cochlear battery, gradually loses its ability to maintain the endocochlear potential, leading to impaired hair cell function and progressive hearing loss. Single‐cell sequencing reveals age‐related cellular changes in the cochlea, providing insights into the underlying mechanisms of aging and potential ...

Anti‐Inflammatory Mechanisms of Selenium Nanosheets in Ulcerative Colitis: Protein Corona, GP130 Interaction, and Transcriptomic Profile

Advanced Science, EarlyView.
SeNSs provide a biocompatible, anti‐inflammatory UC therapy. SeNSs form protein coronas enriched with AKT/PI3K/NF‐κB pathway proteins, suppress GP130 via hydrophobic interactions, and inhibit pro‐inflammatory cytokines. In DSS‐induced UC mice, SeNSs reduce inflammation, tissue damage, and disease activity by modulating cytokine, chemokine, and ...

Genomic analysis of Burkholderia sp. ISTR5 for biofunneling of lignin-derived compounds

Biotechnology for Biofuels, 2019
Background Lignin is the second most abundant natural polymer on earth. Industries using lignocellulosic biomass as feedstock generate a considerable amount of lignin as a byproduct with minimal usage.

A survey of genes encoding H2O2-producing GMC oxidoreductases in 10 Polyporales genomes

Mycologia, 2015
The genomes of three representative Polyporales (Bjerkandera adusta, Phlebia brevispora and a member of the Ganoderma lucidum complex) recently were sequenced to expand our knowledge on the diversity and distribution of genes involved in degradation of ...

Micro‐Environment Programmable Quinoline COFs for High‐Performance Photocatalytic H2O2 Generation and Benzylamine Coupling

Advanced Science, EarlyView.
A series of bio‐inspired quinoline‐based covalent organic frameworks (COFs) with varying substituents (‐R) are synthesized via multi‐component reactions. These substituents demonstrated a pronounced structure‐property relationship between their electronic effects (Hammett parameter, σp) and the photocatalytic H₂O₂ production rate, as well as the ...
