Researchers have demonstrated a technique that uses powdered eggshells to produce high-quality magnesium alloys, which have a wide variety of automotive, aerospace and biomedical applications.
Researchers reviewed advances in alloy-based anodes for rechargeable magnesium batteries, comparing Mg-free hosts, Mg-containing alloys and alloy-derived surface modifications as routes to improve reversibility, Mg²? transport and electrolyte compatibility. The review finds that material structure and interphase chemistry strongly influence performance, while higher alloy-anode operating potentials can reduce full-cell voltage, and practical validation remains a major research priority.
A prospective life cycle assessment of 37 metals found that net-zero energy technologies will increase mining-related environmental damage, especially from copper, nickel, and aluminum. Even so, the modeled climate benefits of deeper decarbonization outweighed the added metal burden by roughly 400 to 1.
SPECTRO Analytical Instruments has introduced the new, improved SPECTROSCOUT kt portable ED-XRF analyzer for rapid, reliable analysis of precious metals and alloys on the spot.
Researchers showed that strong metal-polymer bonding depends on electron donation from polymer functional groups into vacant orbitals on oxidized metal surfaces. By engineering oxygen vacancies and carboxyl groups, they increased the tensile-shear strength of magnesium alloy/CFRTP joints by more than 400%.
Researchers combined density functional theory, machine-learning-enhanced transition-state calculations, and microkinetic modeling to screen 12 Ni-based ternary alloys for nitric oxide reduction under representative aircraft exhaust conditions. The analysis identified four promising candidates, with Ni-Cr-Pt offering the strongest predicted balance of catalytic activity, stability, carbon resistance, and material cost, although experimental validation is still required.
When Aaron Nicholas served in the U.S. Army, he became familiar with “Hail Mary” scenarios where unanticipated, high-pressure conditions push a team to succeed in ways that normal circumstances would not.
SPECTRO Analytical Instruments has introduced the SPECTROPORT LIBS PXL01 portable OES metals analyzer for metals analysis in the field.
Anyone who has ever been frustrated by an overheating mobile phone or wondered how devices will withstand the heat generated by artificial intelligence (AI) applications may be excited to learn about a recent discovery that challenges long-standing assumptions about cooling pathways in electronics.
A study shows that cathodic hydrogen charging affects the integrity of stainless steel, revealing links between surface morphology, hydrogen uptake, and impurity deposits.
