Upcycling plastic waste into single-atom catalysts (SACs) not only offers a sustainable solution for plastic waste management but also yields valuable functional materials for catalytic applications. Here, we report a simple and scalable method to transform various types of plastics, including polyethylene, polypropylene, polystyrene, polyethylene terephthalate, polyvinyl chloride, and their mixtures, into a diversity of porous SACs with different coordination chemistry and their excellent applications in a variety of catalytic reactions. Lamellar transition metal chloride salts (Ni, Fe, Co, Mn, and Cu) are employed as a template and catalyst for confined carbonization of plastics into layered SACs.

The conversion of natural desert vegetation to artificial sand-fixing vegetation significantly impacts the diversity of ground arthropods across various trophic levels. Consequently, this change modifies the structure and function of arthropod-dominated soil food webs, thereby influencing soil multifunctionality. In this study, we set up a vegetation gradient in the desert-oasis ecotone of Zhangye Oasis, Hexi Corridor, spanning from natural desert vegetation (mobile and fixed sandy dunes) to artificial fixed sandy vegetation (5-, 10-, 20- and 30- year-old Haloxylon ammodendron plantations).

Kagomé lattice magnets have recently garnered significant interest due to the pronounced transverse transport characteristics, particularly in thermoelectric and spintronic applications, stemming from the interplay between topology and magnetism. Here, a comprehensive investigation of the magnetic, electrical, and thermoelectric transport properties, as well as the complex spin configurations, is conducted in a polycrystalline Kagomé ferromagnet GdCo. Strikingly, a giant anomalous Hall conductivity ≈2125 S cm is obtained at T = 10 K, which is primarily governed by the extrinsic skew-scattering mechanism.

Photon-counting dual-comb spectroscopy (DCS) opens new possibilities for deploying DCS in scenarios previously constrained by limited detection sensitivity. However, inevitable optical path fluctuations hinder its practical implementation. Here, we propose a method to ensure the long-term stability of photon-counting DCS, overcoming turbulent optical paths, achieving attowatt-level detection sensitivity and quick acquisition times.

It is well known that two-dimensional (2D) van der Waals (vdW) heterobilayers may undergo symmetry breaking in some specific stacking configurations, thus presenting three states (AA, AB, BA) with different out-of-plane (OOP) polarization, which is electrically switchable interlayer sliding. Here, we find that in two vdW heterobilayers (S-g-CN/graphene and T-g-CN/graphene) formed by a g-CN (S-g-CN and T-g-CN) monolayer and graphene monolayer, interlayer sliding can not only switch the OOP polarization, but also change the in-plane (IP) piezoelectric properties of the T-g-CN/graphene heterobilayer, between positive and negative piezoelectricity, which we call . We show first-principles evidence that the strong charge transfer of graphene contributes to the charge redistribution in graphene induced by the in-plane holes of g-CN, so that stacking configurations with different piezoelectric properties appear in the switching process of interlayer sliding.

To address the challenges of low hydrogen peroxide utilization efficiency and excessive iron sludge accumulation in conventional Fenton processes, metal-free carbon cocatalysts harness their cost-effectiveness, ecofriendliness, and modifiable surface to propel green and enhanced Fenton chemistry. Their cocatalytic efficacy stems from structural features (pore architecture, hybridization state, and dimension) and surface properties (defect, heteroatom, functional group, graphitic structure, and site distribution), resulting in carbon cocatalysts playing multifaceted roles in assisting Fenton systems. This overview provides mechanistic insights into carbon cocatalyzed Fenton reactions, focusing on electron sources for iron reduction, and categorizes mechanisms into three approaches (electron donors, carbon-Fe(III) complexes, and electron mediators).

Quantification of low-abundance proteins in biofluids using affordable and portable biosensors stands as the top priority for point-of-care testing and in-field disease screening/monitoring. Herein, we propose a cellphone-based portable immunoassay platform coupled with an intelligent single microbead (SMB) bubbling visualization mechanism, which allows for facile, low-cost, and highly sensitive protein analysis. The use of solely an SMB as the immunocarrier can remarkably boost the sensitivity by superenriching the target-mediated, platinum nanoparticle (PtNP)-involved immunocomplexes on its surface.

The interface between high-performance thermoelectric materials and electrodes critically governs the conversion efficiency and long-term reliability of thermoelectric generators under high-temperature operation. Here, we propose AlCoCrFeNi high-entropy alloys (HEA) as barrier layers to bond Cu-W electrodes with p-type skutterudite (p-SKD) thermoelectric materials. The HEA/p-SKD interface exhibited excellent chemical bonding with a stable and controllable reaction layer, forming a dense, defect-free (Fe,Ni,Co,Cr)Sb phase (thickness of ~2.

The sustainable development of major grain-producing areas necessitates a coupling coordination between ecosystem functions, while carefully considering their responses to human activities. However, our understanding of how human activities influence this coupling coordination in ecosystem functions remains limited. This study establishes an assessment framework for the coupling coordination of ecosystem functions from the production-living-ecology perspective in the Jianghan Plain (JHP), particularly by utilizing multi-source data and relevant geographic spatial models.

Autism is characterized by two key diagnostic criteria including social deficits and repetitive behaviors. However, the underlying neural circuit dysfunction that accounts for these coexisting symptoms in autism remains poorly understood. Here we revealed that prenatal valproate exposure induced functional alterations of dopaminergic projections from substantia nigra pars compacta (SNc) to dorsomedial striatum (DMS).

Memory generalization allows an organism to adapt to new conditions, but overgeneralization of fear or traumatic experiences can be detrimental to survival and contributes to the development of various mental disorders. However, the cellular and molecular mechanisms underlying fear memory generalization, especially in the hippocampus, remain largely unknown. In this study, utilizing a well-established mouse model of fear memory generalization, we investigated the role of endocannabinoids (eCBs)-mediated GABAergic synaptic inputs to hippocampal pyramidal neurons in regulating contextual fear memory generalization.

Super-resolution imaging has revolutionized our ability to visualize biological structures at subcellular scales. However, deep-tissue super-resolution imaging remains constrained by background interference, which leads to limited depth penetration and compromised imaging fidelity. To overcome these challenges, we propose a novel imaging system, confocal² spinning-disk image scanning microscopy (CSD-ISM).

When a third layer of graphene is transferred on top of twisted bilayer graphene with a second twist, the atomic and electronic structure of the system can be significantly enriched. Generally, the two coexisting moiré superlattices give rise to a higher-order moiré-of-moiré (MoM) superlattice, with a plethora of new length scales and associated novel quantum phenomena. This article reviews the current theoretical understanding and experimental observations of twisted trilayer graphene MoM (or supermoiré) superlattices, and the theoretical predictions and ongoing experimental efforts for unraveling rich exotic quantum phenomena and underlying physics.
