Enhancement mechanism of Ce-Ni-modified vanadium–titanium magnetite in chemical looping hydrogen production

Vanadium-titanium magnetite concentrate (VTM) oxygen carriers suffer from inherently low redox activity and sluggish oxygen migration rate, which severely constrain their application in high-efficiency chemical looping hydrogen production. To overcome these limitations, this stud...

Brønsted Acid-Catalyzed Nitroso-Diels–Alder Reaction of 2-Trifluoroacetamido-1,3-dienes

Abstract The nitroso-Diels–Alder (NDA) reaction represents a powerful strategy for the assembly of 3,6-dihydro-1,2-oxazines for nearly a century, owing to its efficiency and broad utility in synthesizing natural products and bioactive molecules. Despite these advancements, tradit...

Heat as a Located Constraint on Grain Production in a Humid Basin: Implications for Climate-Adaptive Land Management

In humid agricultural regions, where heat and water deficit are decoupled, temperature acts on crops in two opposed ways: moderate warmth advances development, whereas extreme heat damages it, and land management must distinguish them. This study examined the temperature response...

Acyl-CoA Oxidase-Mediated β-Oxidation Regulates the Lifestyle Transition of Metarhizium rileyi from Insect Pathogen to Plant Mutualist

Abstract Metarhizium rileyi as a widely distributed insect pathogenic fungus, has a promising application prospect in pest control. This study investigates M. rileyi strain XSBN200920 following its endophytic colonization of Nicotiana benthamiana. The fungus establishes systemic...

High‐Resolution Temperature and Precipitation Variability in Northeast Asia Since the Last Glacial Maximum Recorded in an Annually Laminated Maar Lake

Abstract Temperature and precipitation variability in monsoonal Asia is central to understanding regional climate dynamics and global teleconnections. How post‐LGM warming and hydroclimate change unfolded in Northeast Asia, and how they were linked to external forcing, remain poo...

A trans-therapeutic signature of recovery in internet gaming disorder: From shared network reorganization to molecular underpinnings.

Background and aims: A variety of self-regulation interventions have shown efficacy in treating Internet Gaming Disorder (IGD), but their shared and unique neurobiological mechanisms remain unclear. This study aims to identify a common, trans-therapeutic neural signature of recov...

Enhanced photocatalytic hydrogen production via Eosin Y-sensitized g-C3N4 nanotubes

Photocatalytic hydrogen production offers a promising strategy to address energy and environmental crises. Graphitic carbon nitride (g-C 3 N 4 ) is a competitive photocatalyst, yet facile controllable fabrication of high-activity one-dimensional g-C 3 N 4 remains challenging. Her...

Schooling as urban asset: Education, capital and governance in entrepreneurial Chinese city

This paper examines how schooling is being reconstituted as a strategic urban asset in contemporary China. Moving beyond its conventional role as a public good, elite education is increasingly mobilised within a model of education-led entrepreneurial governance. Drawing on an in-...

Photothermal catalytic conversion of nonanoic acid into bio-jet fuel-range alkanes

The substitution of petroleum-derived jet fuel with biomass-derived alternatives is a promising strategy to address the energy crisis and reduce fossil-resource dependence. However, the efficient conversion of biomass-derived feedstocks into bio-jet fuel-range alkanes remains cha...

Numerical simulation of motor neural system transmission models driven by multiplicative white noise: mean-square stability and convergence analysis

The signal transmission of motor neural system is inherently subject to random perturbations. Understanding the regulatory role of such noise in neural information encoding remains a central challenge in computational neuroscience and applied mathematics. This paper develops a pr...
