Surface Engineering‐Induced d‐Band Center Down‐Regulation in High‐Entropy Alloy Nanowires for Enhanced Nanozyme Catalysis

open access: yesAdvanced Science, EarlyView.
PtRuFeCoNi HEA NWs are synthesized by adjusting the metal composition and surface‐engineered with PDA to create HEA NWs@PDA nanozymes with superior catalytic activities and photothermal properties. DFT calculations confirm that self‐polymerized PDA surface engineering moderately lowers the d‐band center of the HEAs, optimizes the surface charge ...

Highly Stretchable, Self‐Healable, and Conductive Gelatin Methacryloyl Hydrogel for Long‐Lasting Wearable Tactile Sensors

open access: yesAdvanced Science, EarlyView.
Gelatin methacryloyl hydrogel, which possesses high stretchability, tensile strength, toughness, and autonomous self‐healing capability at room temperature, is developed through the introduction of interpenetrating networks, hierarchical hydrogen bonds (weak and strong H‐bonds), and borate ester bonds.

A Soft‐Soft Contact Triboelectric Nanogenerator with a Ternary Four‐Phase Structure for Self‐Powered High‐Efficiency Dust Removal on Mars

open access: yesAdvanced Science, EarlyView.
The frequent dust storms and charged dust particles on Mars pose significant challenges to the power generation efficiency and service life of solar panels during exploration missions. This paper proposes a novel wind‐driven ternary four‐phase soft‐soft contact triboelectric nanogenerator (FPS‐TENG) for dust removal.

Development and Breeding of Herbicide‐Resistant Sorghum for Effective Cereal‐Legume Intercropping

open access: yesAdvanced Science, EarlyView.
This study identified two SbALS mutations (A93T and S624N) conferring robust herbicide resistance in sorghum, facilitating efficient weed control. Structural analysis revealed that imazamox resistance is mediated by disrupted herbicide binding. Furthermore, 126 imazamox resistant soybean varieties are screened for sorghum‐soybean intercropping ...

Gas Bubbles from Biodegradable Magnesium Implants Convey Mechanical Cues and Promote Immune Cell Stimulation

open access: yesAdvanced Science, EarlyView.
Bubbles in soft tissue are the unavoidable consequence of magnesium implant degradation in patients, yet their biological significance remains unclear. Using advanced imaging and spatial transcriptomics, this study reveals a pronounced inflammatory and mechanical response near bubbles, contrasting with pro‐regenerative events closer to the implant ...

Twin Toughening‐Driven Martensitic Transformation Strategy Synergistic Improvement for Plasticity‐Thermal Shock Resistance of (Hf─Zr─Ti)C Ceramic Coating in Severe Thermal Environments

open access: yesAdvanced Science, EarlyView.
A “ceramic self‐toughening strategy” is introduced for enhancing the plasticity and thermal shock resistance of (Hf─Zr─Ti)C coatings through twin toughening‐driven martensitic transformations in oxide scales. It facilitated the formation of stable, dense, and high‐toughness oxide scales after repeat ablation, and endowed prepared coatings with superior

Vertically Aligned Carbon Nanotube Mechano‐Electrochemical Generator for Ultralow‐Frequency Ocean Wave Monitoring

open access: yesAdvanced Science, EarlyView.
A mechano‐electrochemical generator is proposed that harvests energy from ultralow‐frequency waves below 0.01 Hz for self‐powered disaster monitoring. The generator minimizes signal distortion, enabling precise measurement of subtle waves with overlapping frequencies.

Multi‐Mechanical Regulation of 3D Printed Triply Periodic Hyperbolic Surfaces via Fourier Synthesis‐Based Free Modeling

open access: yesAdvanced Science, EarlyView.
Arbitrary structural regulations of triple periodic hyperbolic surfaces are achieved using mathematical Fourier construction and 3D printing technology, enriching the geometric forms and achieving optimized mechanical behaviors. Abstract Triply periodic hyperbolic surfaces (TPHSs) have attracted significant attention due to their exceptional ...

Severe Plastic Deformation of Steels

BHM Berg- und Hüttenmännische Monatshefte, 2008
In order to demonstrate the structural changes in steels during severe plastic deformation (SPD), Armco iron, a ferritic steel P800 and a pearlitic rail steel S900A are subjected to a high pressure torsion (HPT) deformation process. The microstructural evolution, the changes in microhardness and the flow stress behaviour are investigated.
