Molecular Diode‐Based Covalent Organic Frameworks: Imine Orientation‐Driven Acid‐Base Switching Photocatalytic H2 Production

Advanced Science, EarlyView.
Molecular diode‐based covalent organic frameworks (COFs) enable pH‐responsive current rectification, dynamically reversing electron flow to toggle photocatalytic hydrogen evolution activity between acidic and alkaline environments. ABSTRACT Donor–acceptor type covalent organic frameworks (D–A COFs) have emerged as a promising class of photocatalytic ...

Glucuronolactone Promotes Mucin Sulfation to Alleviate Deoxynivalenol‐Induced Intestinal Injury via Microbiota‐Dependent and ‐Independent AHR Activation

Advanced Science, EarlyView.
Glucuronolactone (GLU) as a natural metabolite of glucose, increases Lactobacillus amylovorus abundance and luminal IAA level to activate AHR signaling. In addition, GLU itself can directly elevate AHR signaling activity independently of microbiota and IAA.

Synthesis of CuO Nanoparticles from Copper(II) Schiff Base Complex: Evaluation via Thermal Decomposition

Indonesian Journal of Chemistry
Copper oxide (CuO) nanoparticles were synthesized through the thermal decomposition of a copper(II) Schiff-base complex. The complex was formed by reacting cupric acetate with a Schiff base in a 2:1 metal-to-ligand ratio.

Harnessing Transformation of Metal‐Ligand Coordination in Dinuclear Ni(II)‐Schiff Base Coordination Polymer for Promoting Electrochemical Oxygen Evolution

Advanced Science, EarlyView.
Ni–Schiff base coordination polymer [Ni2(tmd)2]n was synthesized and applied to enhance alkaline OER by virtue of its transformation between 5‐ and 6‐coordinate Ni sites along with the spin state exchange. ABSTRACT One of the major challenges in overall water splitting is improving the sluggish kinetics of the anodic oxygen evolution reaction (OER ...

Engineered Bacterial Ligand From Streptococcus pneumoniae on Macroporous Resins for Selective Affinity Capture of Secretory IgA

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Secretory immunoglobulin A (sIgA) is a promising emerging biopharmaceutical candidate, but it currently lacks a standardized platform for purification. To address this, a novel affinity chromatography resin was developed by immobilizing protein variants of the Streptococcus pneumoniae surface protein, SpsA, as an affinity ligand.
