Computational design of Al-Mg-Si alloy compositions and optimization of its heat treatment

Currently, a major scientific and engineering hotspot lies in the synergistic enhancement of aluminum alloy properties through optimizing composition and heat treatment processes, aimed at both boosting performance and conserving energy. In 6xxx-series aluminum alloys, the intera...

Fluorine‐Driven Interfacial Reconfiguration for pH‐Universal CO 2 Electrolysis at High Current Densities via Enhanced CO 2 Enrichment and Proton Feeding

ABSTRACT High‐rate CO 2 electroreduction is challenged by the conflict between sluggish CO 2 activation and hydrogen evolution at high currents, particularly under pH‐universal and dilute CO 2 conditions. In this study, a defective fluorine‐modified bismuth (F‐Bi) with electron‐r...

Infrared-Transparent Polymer Nanofiber Networks for Polarization Camouflage

Conventional thermal camouflage often suffers from severe Fresnel-induced polarization splitting at large observation angles, rendering targets conspicuous to polarimetric detection. Existing nanophotonic solutions are hindered by narrow spectral bands, coupled optical responses,...

Development and performance of filler-free buckling-restrained shape memory alloy devices for self-centering seismic applications

This study proposes a novel filler-free buckling-restrained SMA device for self-centering seismic applications. The proposed device consists of an SMA core bar, a confining tube, two swaged sleeves, two restraining sleeves, and two connection parts. The SMA bar includes a fuse pa...

Radical‐Integrated Phosphorus‐Containing Ionic Organic Cage for Efficient Gold Recovery From Complex Liquids

ABSTRACT The development of advanced adsorbents for the selective and efficient recovery of gold from complex aqueous matrices is of paramount importance for sustainable resource recycling. Here, we report a phosphorus‐functionalized, quaternized ammonium cages (Phos‐QA‐Cage‐Cl)...

Tribochemical and tribomechanical effect of TiO 2 nanoparticle: Different influence on MoDTC and ZDDP additives

Abstract This study investigates the formulation-dependent tribochemical regulation of TiO2 nanoparticles in molybdenum dithiocarbamate (MoDTC), zinc dialkyldithiophosphate (ZDDP), and their blended lubricant systems. Reciprocating ball-on-disk tribological tests were conducted u...
