Molecular Dynamics Study of Melt Structure and Transport Properties of Mg‒Al Alloy

Materials Genome Engineering Advances, EarlyView.
The structural evolution and transport coefficients of the Mg‐Al alloy melt at different temperatures were investigated using molecular dynamics simulation methods. By establishing relationships among structure, diffusion, and viscosity, the microscopic mechanisms behind the temperature‐induced changes in transport properties are revealed. ABSTRACT The

Rhizosphere microbial detoxification and phosphorus solubilization drive ecological remediation of Pb–Zn contaminated soils

PLANTS, PEOPLE, PLANET, EarlyView.
Heavy metal contamination of soils poses a serious threat to ecosystem health and food security worldwide. This study investigated how native plants, such as Artemisia annua and Buddleja davidii, interact with soil microbes in Pb–Zn waste slag areas. We found that these plants stimulate microbes, which improve phosphorus availability and reduce metal ...

Designing High‐Strength and High‐Ductility Cast Mg–Zn–Al–Mn–Sn Alloys via τ‐Mg32(Al,Zn)49 Phase Tuning and Twin Boundary Toughening Optimisation

Rare Metals, EarlyView.
ABSTRACT Achieving a simultaneous enhancement of strength and ductility remains a critical bottleneck for the large‐scale and cost‐effective engineering application of magnesium alloys. In this work, guided by first‐principles calculations, we tailored the τ‐Mg32(Al,Zn)49 phase and optimised twin boundary, thereby designing and successfully ...

Leaching of copper slags in sulphuric acid and alkaline glycine media

Frontiers in Chemical Engineering
Copper slag is industrial waste, having fayalite and magnetite as main phases, copper is present in the form of chalcopyrite and chalcosine. However, the complex structure of the slag makes the dissolution process difficult, which is why methods have ...
