Extending the technology acceptance model with trust and perceived risk to explain young-old adults’ virtual reality technology adoption

Virtual reality (VR) technology is a valuable tool to address the evolving needs of young-old adults. This study investigated the factors influencing the adoption of VR technology among young-old adults, extending the technology acceptance model by incorporating trust and perceiv...

Potential‐Programmed Mo Dissolution–Induced Reconstruction of Commercial NiMo Foam for High‐Current Alkaline Hydrogen Evolution

ABSTRACT Hydrogen production via water electrolysis is a sustainable pathway, yet its widespread application is hindered by high energy consumption. Therefore, the development of efficient non‐precious‐metal catalysts for the hydrogen evolution reaction (HER) is of great importan...

Modeling and quantification of beam steering uncertainties in high-pressure laser absorption spectroscopy of non-uniform physical fields

Beam steering induced by refractive index gradients poses a significant challenge for laser absorption spectroscopy in high-pressure, non-uniform combustion environments. This work establishes a physics-based framework to model and quantify beam steering effects on path-integrate...

Synthesis and performance optimization of an integrated tandem beam splitting module with perovskite solar cells

The global energy transition demands increasingly efficient utilization of renewable energy sources. Solar spectral beam splitting technology, which directs photons of different wavelengths to photovoltaic and photothermal units respectively, offers a promising pathway toward com...

Autothermal Biomass and Plastic Cogasification for Hydrogen-Rich Syngas Production: Process and Sustainability Assessment

Abstract Transitioning to sustainable energy and chemical systems requires circular pathways that valorize waste, manage carbon emissions, and meet global energy demands. Plastic waste and biomass cogasification in the presence of CO2 to produce hydrogen-rich syngas offer viable...

Hydrogel-Based Self-powered Sensing for Muscle Activity Monitoring and Safe Rehabilitation Robotics

Abstract Upper-limb motor dysfunction is a common sequela following neurological and orthopedic injuries and can severely impair functional recovery. However, conventional rehabilitation approaches remain limited by subjective assessments and the lack of muscle-specific physiolog...

Specific targeting of MR1-antigen complexes using nanobodies

T cell receptor mimic (TCRm) antibodies that bind peptide–human leukocyte antigen complexes have great therapeutic potential. Major histocompatibility complex class I–related protein 1 (MR1) exhibits limited polymorphism and presents conserved metabolites, such as 5-OP-RU, derive...

Abstract Photocatalytic water splitting for hydrogen production is a crucial pathway for renewable energy conversion. However, conventional photocatalysts commonly face challenges such as low light absorption efficiency and severe recombination of photogenerated charge carriers....

Control of ice thickness in cryo-EM via confinement

Achieving thin ice with optimal thickness is a prerequisite for successful cryo-EM analysis of embedded macromolecules. Despite decades of effort, precise control of ice thickness in cryo-EM remains a major challenge. Here we reveal that the intrinsic instability of sub-100-nm li...

Nonlinear time-history analysis of degrading structures under spectrum-compatible shallow moonquakes synthesized from Apollo records

Shallow moonquakes are characterized by long durations and slow energy attenuation, posing a significant threat to the seismic safety of future lunar surface structures. Based on high-quality short-period records obtained from the Apollo Passive Seismic Experiment, this study emp...

Prussian blue regulates ion dynamics in perovskite solar cells

Perovskite photovoltaics are limited by structural instabilities initiated during crystallization and amplified under operation. We report that a lattice-matched Prussian blue scaffold directs heterogeneous nucleation to produce highly oriented, strain-relaxed films. Its redox-ac...

From single-sequence structure prediction to protein fitness landscape through a composable, epistasis-aware mutation atlas

Mapping the multi-mutant fitness landscape is vital to protein engineering, but is challenging due to the vast combinatorial sequence space awaiting exploration. A central difficulty lies in the accurate and efficient modeling of non-additive epistatic effects among individual mu...

Political Connections, Financial Constraints, and Corporate Taxation

Abstract We find that the effect of political connections on tax planning depends on firms’ financial conditions. After increased political connections, financially unconstrained firms increase tax planning and spending on tax services, as documented in prior studies, whereas con...

The holographic multi-entropy cone

A bstract We generalize the holographic entropy cone (HEC) to the holographic multi-entropy cone (HMEC) by adjoining multi-entropy coordinates to the standard entropy coordinates. We show that holographic states, through their multi-entropy vectors, form a rational polyhedral con...
