Waste three-way catalysts (TWCs) and waste LiCoO batteries represent critical environmental challenges due to hazardous components yet contain high-value resources, and their recycling has garnered widespread attention. We propose a novel 'waste-to-waste' synergistic recycling where spent LiCoO batteries reconstruct mineral phases of waste TWCs, enabling co-recovery of platinum group metals and Li/Co without traditional oxidants. However, the environmental performance of this process still requires further analysis.

Electrically Conductive Hydrogels for Wound Healing.

Adv Wound Care (New Rochelle)

September 2025

Beijing Laboratory of Biomedical Materials, State Key Laboratory of Organic-Inorganic Composites, Beijing University of Chemical Technology, Beijing, PR China.

Wound healing is a complex, tightly regulated process involving a range of enzymes, growth factors, and cytokines that coordinate cellular activities essential for tissue repair and wound closure. However, in cases of extensive or severe injury, the intrinsic repair mechanisms are often insufficient, underscoring the need for advanced therapeutic strategies to accelerate healing and minimize scar formation. Electrically conductive hydrogels (ECHs), combining the advantageous properties of hydrogels with the physiological and electrochemical characteristics of conductive materials, present a safer and more convenient alternative to traditional electrode-based electrical stimulation (ES) for treating chronic and nonhealing wounds.

Origin and mitigation of the imprint effect in hafnia-based ferroelectrics.

Nanoscale

September 2025

School of Materials Science and Engineering, Wuhan University of Technology, Wuhan 430070, People's Republic of China.

The potential of hafnia-based ferroelectric materials for Ferroelectric Random Access Memory (FeRAM) applications is limited by the imprint effect, which compromises readout reliability. Here, we systematically investigate the asymmetric imprint behavior in W/HfZrO/W ferroelectric capacitors, demonstrating that the imprint direction correlates directly with the ferroelectric polarization state. Notably, a pre-pulse of specific polarity can temporarily suppress the imprint effect.

Globular proteins as functional-mechanical materials: a multiscale perspective on design, processing, and applications.

Mater Horiz

September 2025

MOE Key Laboratory of Macromolecule Synthesis and Functionalization, Department of Polymer Science and Engineering, Zhejiang University, Hangzhou, 310027, PR China.

Globular proteins, traditionally regarded as non-structural biomolecules due to the limited load-bearing capacity in their monomeric states, are increasingly recognized as valuable building blocks for functional-mechanical materials. Their inherent bioactivity, chemical versatility, and structural tunability enable the design of materials that combine biological functionality with tailored mechanical performance. This review highlights recent advances in engineering globular proteins-spanning natural systems (serum albumins, enzymes, milk globulins, silk sericin, and soy protein isolates) to recombinant architectures including tandem-repeat proteins-into functional-mechanical platforms.

Type-I Supramolecular Photosensitizer Enables GSH Depletion by Hydrogen Atom Transfer.

J Am Chem Soc

September 2025

Key Laboratory of Radiopharmaceuticals, Ministry of Education, College of Chemistry, Beijing Normal University, Beijing 100875, P. R. China.

Photodynamic therapy (PDT) induces oxidative stress that triggers a compensatory upregulation of intracellular glutathione (GSH), thereby diminishing PDT efficacy. The simultaneous generation of reactive oxygen species and depletion of GSH holds promise for amplifying oxidative damage and enhancing therapeutic outcomes yet remains a challenge. In this work, we present a Type-I supramolecular photosensitizer designed to deplete GSH through a hydrogen atom transfer mechanism while concurrently generating superoxide radicals.

Respiratory syncytial virus (RSV) is a major pathogen causing acute respiratory infections, and the RSV fusion glycoprotein (F) has been identified as a key target for developing small-molecule inhibitors. Based on our prior identification of lonafarnib as an F protein inhibitor, medicinal chemistry efforts led to the development of , which exhibits significantly enhanced potency against both laboratory and clinical RSV isolates in cellular assays. Time-of-addition and SPR assays indicate that inhibits viral entry by targeting the RSV F protein, but has farnesyltransferase-independent antiviral efficacy.

Long-Lived Charge-Transfer State and Interfacial Lock in Double-Cable Conjugated Polymers Enable Efficient and Stable Organic Solar Cells.

Angew Chem Int Ed Engl

September 2025

Beijing Advanced Innovation Center for Soft Matter Science and Engineering & State Key Laboratory of Organic-Inorganic Composites, Beijing University of Chemical Technology, Beijing, 100029, P.R. China.

The donor/acceptor (D/A) interfaces in bulk heterojunction (BHJ) organic solar cells (OSCs) critically govern exciton dissociation and molecular diffusion, determining both efficiency and stability. Herein, we design a double-cable conjugated polymer, SC-1F, to insert into a physically-blended D/A system to optimize the interface. We have found that SC-1F spontaneously segregates to the interface through favorable miscibility and heterogeneous nucleation with the acceptor.

One-Pot Sequential Coordination-Covalent Construction of Symmetry-Broken MNO Catalytic Sites in Cobalt-Polyimide Polymers for Nitrate Electroreduction.

Angew Chem Int Ed Engl

September 2025

College of Polymer Science and Engineering, State Key Laboratory of Advanced Polymer Materials, Sichuan University, Chengdu, 610065, P.R. China.

The metal-nitrogen chelated species, MN, have shown promise as efficient electrocatalysts for nitrate reduction, yet the symmetric arrangement of N atoms results in suboptimal adsorption affinity toward reaction substrates and intermediates. The current approaches to breaking the symmetry of MN suffer from inaccuracy and inhomogeneity because of the lack of strategies stemming from molecular design aspects. Herein, we report the construction of symmetry-broken MNO sites in coordination polymers via sequential coordination-covalent control in a one-pot reaction.

Developing artificial hosts with temperature-driven conformational switching behaviors facilitates our understanding of the temperature-dependent allostery and adaptation mechanisms in natural recognition systems. Herein, we report the design and synthesis of three pairs of water-soluble, enantiomeric binaphthalene-based tetraimidazolium macrocycles (SS/RR-1•4Cl- - SS/RR-3•4Cl-) as artificial hosts for exploring sequence-selective recognition of dinucleotides in aqueous media. Owing to the reversible rotational conformation of axially chiral binaphthyl units, SS-1•4Cl- demonstrates the conformational switching, converting from cis-conformation (SS-1) to trans-conformation (SS-1) by increasing temperature, thereby causing the recognition cavity to transition from a closed to an open state.
