Sub-4 nm Pt5Sm Intermetallic Catalyst toward Efficient and Durable Oxygen Reduction for Fuel Cell Applications

Abstract It is remarkably attractive but challenging to develop fine Pt–rare-earth intermetallic catalysts toward efficient and stable oxygen reduction reaction (ORR) for fuel cell applications. In this work, an amino-assisted method was employed to prepare the carbon-supported P...

Research progress on green recycling technologies for lithium-ion batteries based on molten salt methods

The rapid increase in spent lithium-ion batteries (LIBs) has created an urgent demand for recycling technologies that can achieve efficient resource recovery, material regeneration, and reduced environmental impacts. Molten salt methods have attracted increasing attention because...

Cerium-Modified Diatom Biosilica for Lithium-Ion Anodes

Abstract Diatom frustules offer hierarchically porous biosilica templates for sustainable electrode design; however, their low electrical conductivity and limited electrochemically accessible sites constrain lithium-storage performance. In this study, a two-stage cultivation stra...

Toward wind-resilient cable-supported photovoltaic system: nonlinear stiffness, dynamic identification, and parametric instability

Cable-supported flexible photovoltaic (FPV) system is emerging as lightweight low-carbon power-generation structures, but their large-span, low-stiffness configuration makes them susceptible to large-amplitude wind-induced oscillations, for which the conventional small-amplitude...

Site-specific seawater conditions modulate bacterial community responses to ocean alkalinity enhancement

Ocean alkalinity enhancement (OAE) based on alkaline mineral addition is a promising marine carbon dioxide removal (mCDR) strategy. However, knowledge remains limited on how OAE affects microbial communities across heterogeneous ocean environments, which play essential roles in m...

Dual effect of calcium ions on sodium oleate adsorption and spodumene flotation

The flotation of spodumene with sodium oleate is highly sensitive to calcium concentration, but the underlying interfacial mechanisms remain unclear, especially under inhibitory conditions. To address this, we systematically investigate how calcium ions govern the spodumene-oleat...

Surface‐Modified Slag as Partial Replacement of Carbon Black for Green Tire Tread Rubber

ABSTRACT This study adopted hybrid silicone resin to modify industrial slag, and utilized the modified slag as a reinforcing filler to partially substitute carbon black for preparing green radial tire tread compounds. The results demonstrated that hybrid silicone resin was succes...

Revealing Non-Steady-State Structure–Performance Relationship in Plateau-Capacity-Dominated Hard Carbon Anodes for High-Rate Reversible Sodium Storage

Abstract The sodium storage structure–performance relationship of hard carbon anodes has long been regarded as an intrinsic material property and forms the basis for electrode design. This common view, however, does not hold with varying operating temperatures. At room temperatur...

Microbial carbon, nitrogen, and phosphorus metabolism and resistance mechanisms in constructed rapid infiltration systems for treating mineral processing wastewater under low temperature

In this study, constructed rapid infiltration systems (CRIS) packed with coke or modified red mud were used to treat mineral processing wastewater (MPW) containing aniline aerofloat (AAF) and ammonium dibutyl dithiophosphate (ADD) at 10 °C. Microbial community dynamics and metage...

Unraveling the Importance of Carboxyl Groups in Photochemically Excited Triplet Formation of Chromophoric Dissolved Organic Matter

Abstract Carboxylation and decarboxylation are among the most ubiquitous processes in chromophoric dissolved organic matter (CDOM) transformation, occurring during humification, photooxidation, and microbial activity. However, their impacts on the formation of excited triplet-sta...

Transforming waste into multifunctional biochar catalysts for pollution control: Synthesis strategies, catalytic mechanisms, and practical challenges

Abstract Converting waste feedstocks into multifunctional biochar catalysts provides a promising route for coupling solid‐waste valorization with pollution control. However, existing studies often emphasize individual removal performance, while the relationships among feedstock c...

Imidazole-Mediated Size-Tunable ZIF(Cu) Particles Enhance the CO2 Separation Performance of Pebax-Based MMMs

Abstract The particle size of ZIFs has a significant effect on the CO2 separation performance of mixed matrix membranes (MMMs). Herein, an imidazole-mediated protonation strategy was developed to regulate the particle size of ZIF(Cu), achieving tunable sizes spanning more than on...

An epoxy latent curing agent with outstanding storage stability and processing convenience

The latent curing of epoxy resins has long been constrained by the inherent dilemma between easy deactivation at room temperature and the demand for rapid curing at elevated temperatures, severely limiting their large-scale applications. Herein, we innovatively constructed a Mn 2...

Global rice methane emissions tripled over six decades amid declining emission intensity

Abstract Rice paddies are among the largest anthropogenic sources of methane (CH4), yet substantial uncertainties persist in the long-term magnitude and spatiotemporal dynamics of the emissions. Here we show a spatially explicit global estimate of rice CH4 emissions from 1961 to...

Triaxial Compressive Properties of Graphene Oxide-Modified Concrete

Thirty specimens of graphene oxide-modified concrete (GOMC) were prepared with curing age, graphene oxide (GO) dosage, and lateral confining pressure as the test variables. Complete stress–strain curves under triaxial compression were obtained, elucidating the failure mechanism a...
