Ductile B2 Intermetallics‐Driven Strength‐Ductility Synergy in Heterolaminated Multi‐Principal Element Alloys

Advanced Science, EarlyView.
Intrinsic phase toughening transforms a brittle B2 intermetallic into a plastically deformable, load‐bearing phase, while a heterogeneous laminated architecture suppresses strain localization and interface cracking. The synergy between ductile intermetallics and mesoscale heterogeneity establishes a general design strategy for breaking the long ...

Micro-pitting on bevel- and hypoid gears and its effect on the pitting durability

, 2014
Auf Basis von experimentellen Untersuchungen wurden Rechenverfahren zur Bestimmung der Grauflecken- und Grübchentragfähigkeit abgeleitet. Diese Rechenverfahren berechnen zum einen auf Basis weniger geometrischer Eingaben und Betriebsbedingungen die ...

Probing Electrocatalyst Design for Product Selectivity in CO2 Reduction

Advanced Science, EarlyView.
Selective CO2 electroreduction is controlled by catalyst structure, dynamic surface reconstruction, adsorbate interactions, and reaction microenvironment. This review summarizes Cu‐ and non‐Cu‐based catalysts, single‐atom and molecular systems, degradation pathways, and operando/computational strategies for steering CO2RR toward hydrocarbons ...

Effects of Sliding Conditions on Improvement of Lubrication with Micro Pits in Metal Forming.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 2000
A series of experiments have been conducted using a rolling-type tribometer to investigate the mechanism and lubricating effects of the outflow behavior of lubricant trapped in a pit. Experiments using aluminum and mild steel sheets with regularly arranged pits showed that lubricant flows out along the friction stress direction and moves larger ...

Cicada Wing‐Inspired Skeleton‐GO Networks in Melamine Foams for Multifunctional High‐Performance Composites

Advanced Science, EarlyView.
Inspired by the intricate microstructure of cicada wings, researchers developed a novel in situ skeleton‐graphene membrane architecture within lightweight foams. This bioinspired design dramatically enhances multifunctional performance: vibration attenuation time decreases by ∼83.3%, damping capacity increases by ∼179.3%, and compressive modulus rises ...

A Study on Micro-Pit Texture Parameter Optimization and Its Tribological Properties

Machines
In this paper, the effect of micro-dimple textures (produced by a laser) on the tribological properties of bearings is investigated. This study offers guidelines to reduce the friction torque of the bearing pair and addresses the problem of difficult start-ups after shutdowns.

The IRE1‐XBP1s Axis Drives Inflammatory Osteolysis by Regulating a 5‐HT Dependent Endogenous Anti‐Autophagy Mechanism

Advanced Science, EarlyView.
A previously unrecognized IRE1‐XBP1s‐Slc6a4 signaling axis links endoplasmic reticulum stress to serotonin metabolism, autophagy, and inflammatory osteoclastogenesis. By promoting intracellular serotonin uptake and reducing endogenous 3‐methyladenine accumulation, this pathway accelerates inflammatory bone destruction and provides a promising ...

An analysis of gear wear and micro-pitting evolution during contact fatigue

Journal of Physics: Conference Series
Abstract This work uses contact fatigue tests to study the wear and micro-pitting evolution on gear teeth. The study reveals a competitive relationship between wear and micro-pitting corrosion in gear contact fatigue. Experimental results demonstrate that micro-pitting initially appears at the root of the carburized and quenched gear ...

Dynamic Interfacial pH Stabilization and (002) Oriented Deposition Enabled by Histidine‐Induced Solid Electrolyte Interphase for Highly Reversible Zn Anodes

Advanced Science, EarlyView.
The histidine‐induced ultrathin SEI (Zn(OH)2‐HIS) delivers exceptional anode stability by stabilizing the interfacial pH via a synergistic mechanism of chemical buffering and physical blocking, while inducing dendrite‐free oriented (002) deposition.
