Selective Adsorption of Methyl Acetate from Model Fischer–Tropsch Synthetic Oil on 13X Zeolite: Experimental and Computational Insights

Abstract The efficient removal of ester oxygenates from Fischer–Tropsch (FT) synthetic oil remains challenging due to limited understanding of selective adsorption mechanisms and adsorption kinetics. Herein, a combined experimental and theoretical approach was employed to investi...

Waste-to-value: Spent coffee grounds derived Ni-decorated porous biochar for efficient plasma-catalytic ammonia synthesis

The shift from centralized Haber–Bosch to decentralized renewable ammonia synthesis demands catalysts with high activity and renewable compatibility. Here we report a Ni-decorated porous biochar catalyst (Ni/HBC-2) derived from spent coffee grounds. The optimized support (HBC-2)...

Mobility Control and Solid–Liquid Interface Interaction Mechanisms of Psyllium Gum-enhanced CO2 Foam

Abstract Efficient mobility control is essential for foam-enhanced CO2 flooding and storage, yet the adsorption of chemicals in reservoirs can cause foam destabilization and mobility-control loss. This study investigates the mobility control and solid–liquid interfacial mechanism...

Geochemical Evidence for the Evolution of the Deyang–Anyue Rift in the Ediacaran–Cambrian Period on the Northwestern Margin of the Yangtze Block

Abstract The evolution of a large intracratonic rift trough in the northern Sichuan Basin, China, along the northwestern margin of the Yangtze Block, is documented during the significant Ediacaran–Cambrian Transition (ECT). Three prevailing perspectives exist regarding the specif...

Electrolyte materials and interfacial engineering for high-energy-density aqueous potassium-ion batteries

Abstract Aqueous potassium-ion batteries (AKIBs) have emerged as highly attractive candidates for grid-scale energy storage due to their intrinsic safety, low cost, and fast ion transport kinetics. However, their practical deployment is severely impeded by insufficient energy den...

Controllable Reconstruction of the Ni/MgAl2O4 Catalyst by In Situ Liquid-Phase Reduction Combined with an Adsorption-Impregnation Strategy to Enhance Reaction Performance for MCH Steam Reforming

Abstract Hydrogen production via catalytic steam reforming of high-carbon hydrocarbons, with low cost, strong adaptability, and easy industrialization, is one of the core technologies for addressing the hydrogen supply bottleneck of fuel cells. However, traditional synthesis meth...

Optimal Configuration of Traction Power Supply Systems Based on Deep Reinforcement Learning

To address the coupling among power supply topology, module selection, capacity allocation, and N-2 contingency assessment in flexible traction power supply systems, a deep-reinforcement-learning-guided branch-and-bound method is proposed for equipment siting and sizing. The Acto...

Over 7500 Cycles Achieved in Platinum‐Group‐Metal‐Free Ni–H 2 Battery Through Reversible Hydrogen Spillover

ABSTRACT Traditional Ni–H 2 batteries employing platinum‐group metal (PGM) catalysts exhibit ultralong lifetimes (> 10 000 cycles), yet comparable durability has not been achieved in recently developed PGM‐free systems, mainly due to sluggish hydrogen evolution and oxidation reac...

Mechanistic insights into the divergent pathways of Bayer and Sintered red mud additives in synergistic NO/SO2 conversion during coal co-combustion

As a large amount of solid waste residue generated from alumina industry, the resource utilization of red mud (RM) in fluidized bed is of great significance for achieving pollutant reduction. In this paper, the synergistic conversion mechanisms of NO and SO2 during coal co-combus...

Calculation of water storage space and changes in underground coal mine reservoirs

In view of the limited limited water storage space and unstable structure in traditional caving mining, and the invisibility of goaf leads to the difficulty of accurate calculation of water storage space, this paper proposes a comprehensive technical method for the digitization o...

A superelastic titanium alloy showing nearly temperature-independent high strength and elastic modulus

Lightweight superelastic alloys with temperature-insensitive properties are critical for deep-space exploration devices, yet their development is hindered by the challenge of simultaneously balancing strength, recoverable strain, and temperature sensitivity. Here, we overcome the...
