Thermo-mechanically driven dynamic recovery and residual stress relaxation in high-efficiency deep grinding of single-crystal superalloys

High-efficiency deep grinding (HEDG) is an important process for machining single-crystal superalloy turbine blades, whereas the severe thermo-mechanical coupling and ultrahigh strain rates involved make the evolution of subsurface residual stress difficult to predict accurately....

Probing the Conformational Dynamics of VeCas9 Using High-Resolution Single-Molecule Junctions

Abstract Gene editing enables precise genetic modifications, revolutionizing disease treatment, crop improvement, and biotechnological innovation. VeCas9, a recently identified CRISPR endonuclease from the Veillonella genus, exhibits a broader protospacer adjacent motif recogniti...

Interfacial Dynamic Oxygen Exchange Preserves C─O Bonds for Selective CO 2 ‐to‐Ethanol Electrosynthesis

ABSTRACT Intermediate‐valence copper (Cu + ) is essential for preserving C─O bonds during the electrochemical reduction of CO 2 to ethanol, yet its progressive over‐reduction to Cu 0 under operating potentials inevitably dictates C─O bond cleavage and shifts selectivity toward et...

Digital and Green Transformations: Leveraging Global Value Chains in Belt and Road Initiative

ABSTRACT This study investigates the link between Global Value Chain (GVC), Digital Adoption Index, and Green Transformation Index across 89 Belt and Road (B&R) countries during 2004–2019. The study employs a multi‐regional input–output framework and the System Generalized Me...

Associations of self-efficacy and learning engagement with humanistic caring ability among vocational college nursing students: a structural equation modeling study

Previous studies have investigated the associations of humanistic caring ability (HCA) with self-efficacy (SEF), or learning engagement (LN) among college students. There has been a lack of studies that examine the mediation effect of learning engagement between SEF and humanisti...

Reaction-induced surface/subsurface indium species formation on ZrO2 for enhanced CO2 hydrogenation to methanol

The complex structural evolution of oxide catalysts during CO2 hydrogenation presents both challenges and opportunities for optimizing catalytic performance. This study demonstrates reaction-induced transformation of In2O3 particles into InOx nanolayers and subsurface In-Zr-O sol...
