Copper‐Driven Epithelial Barrier Disruption: A Novel Mechanism of COPD Acute Exacerbations Mediated by the TNF‐α/ATP7A Axis

Advanced Science, EarlyView.
This study reveals a copper‐driven mechanism of COPD acute exacerbations mediated by the TNF‐α/ATP7A axis. TNF‐α suppresses the copper transporter ATP7A via competitive NF‐κB/CREB1/CBP signaling, resulting in intracellular copper accumulation, mitochondrial oxidative stress, and epithelial barrier disruption.

Probing Electrocatalyst Design for Product Selectivity in CO2 Reduction

Advanced Science, EarlyView.
Selective CO2 electroreduction is controlled by catalyst structure, dynamic surface reconstruction, adsorbate interactions, and reaction microenvironment. This review summarizes Cu‐ and non‐Cu‐based catalysts, single‐atom and molecular systems, degradation pathways, and operando/computational strategies for steering CO2RR toward hydrocarbons ...

Covalently Integrated Selenoviologen–N‐Heterocyclic Carbene–Pt Nanoparticles for Visible‐Light‐Driven Hydrogen Evolution

Advanced Science, EarlyView.
A covalently integrated single‐component photocatalyst is constructed by anchoring selenoviologen to platinum nanoparticles via robust N‐heterocyclic carbene ligands. The resulting Pt─C covalent bonds function dually as protective structural scaffolds and direct channels for ultrafast intramolecular electron transfer This precise interfacial ...

Good response with zinc acetate monotherapy in an adolescent affected by severe Wilson disease

La Pediatria Medica e Chirurgica, 2012
We describe a 17-year-old girl with haemolytic anaemia as presentation of Wilson disease. The diagnosis was based on the findings of < 20 mg/dl ceruloplasmin serum level, Kayser-Fleischer ring and Coombs-negative haemolytic anaemia.

Polymer‐Grafted Cu(II) Metal–Organic Polyhedra as Scalable, Melt‐Processable Porous Materials

Advanced Science, EarlyView.
The use of a direct synthetic route to obtain polymer‐grafted Cu(II)‐based metal–organic polyhedra gives rise to a low‐cost and scalable cage. This material combines low‐temperature melting, achieving phase changes while preserving cage integrity, and high CO2 uptake exceeding 0.6 mmol g−1.

A sustainable approach for polyethylene terephthalate waste valorization: optimization and mechanistic study of glycolysis using Zn(OAc)2·2H2O/urea deep eutectic solvent [PDF]

Royal Society Open Science
The chemical recycling of polyethylene terephthalate (PET) via glycolysis is a promising pathway for the circular economy; however, it often requires harsh conditions or expensive catalysts. This study investigates the depolymerization of waste PET using
