Unravelling the initiator‐only stage in alginate grafting: Radical‐induced depolymerization and its impact on acrylamide grafting efficiency

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Free‐radical grafting of natural polymers often assumes that initiators only create active sites before monomer addition. We tested this by exposing sodium alginate to potassium persulphate (KPS) under typical grafting conditions without monomer (acrylamide).

Channel Microenvironment‐Controlled Pillared MOF as Efficient Triboelectric Nanogenerator Material for Self‐Powered Degradation of Organic Pollutants

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The pore microenvironment regulation of metal–organic framework (MOF) significantly enhanced the output performance of triboelectric nanogenerators (TENG) through SC‐SC transformation, which provides a new idea for the construction of self‐powered degradation systems for organic pollutants.

Curvature and Microenvironment Regulation Enable Robust Seawater Electrochemical Hydrogen Peroxide Synthesis for On‐Site Marine Aquaculture

Interdisciplinary Materials, EarlyView.
This work designs pentagon‐defect‐enriched interconnected spherical carbon (PD/IS‐C) via curvature and microenvironment co‐engineering for seawater H2O2 electrosynthesis. Curvature modulates electronic structure to boost reactivity, while local alkaline microenvironment repels Cl− for enhanced stability, endowing PD/IS‐C with exceptional catalytic ...

Substrate Characterization of Mycobacterial Kinase PknG Revealing PknG‐KARS‐MAPK Phosphorylation Signaling Axis in Host

iMetaMed, EarlyView.
This study employed multi‐omics approaches to investigate the regulatory mechanism of Mycobacterium PknG on host cell processes. We found that host lysine‐tRNA ligase (KARS) is a potential substrate of PknG; and PknG can regulate the immune response by catalyzing the phosphorylation of KARS at T592 and T595 sites, affecting the phosphorylation level in
