Impact of Rapid Thermal Annealing on the Structural and Piezoelectric Properties of AlN Thin Films
Advanced Electronic Materials, EarlyView.Aluminum nitride (AlN) is a biocompatible piezoelectric material suitable for energy harvesting in MEMS resonators. Through rapid thermal annealing, a threshold for CMOS‐compatible processes is established. AlN improved its crystallinity and enhanced the piezoelectric coefficient by ∼160%. Devices show an improvement in the electromechanical properties

Advanced Physics Research, EarlyView.The mechanism and kinetics of selective GaAs growth on Si nanotip wafers via nanoheteroepitaxy were investigated as a function of pitch (center‐to‐center nanotip spacing). The pitch dependence reveals distinct surface‐diffusion‐controlled regimes, demonstrating that lateral Ga adatom transport on the SiO2 mask governs material redistribution and ...

Peroxodisulfate‐Enhanced Leaching of Deep‐Sea Manganese Crusts and Sulfides
Chemie Ingenieur Technik, EarlyView.Ammonium peroxodisulfate enables efficient leaching of deep‐sea manganese crusts and massive sulfides while offering electrolytic recycling. High leaching yields for V, Mn, Co, Mo, Sn, and W, along with complete leaching of As and Sb, highlight its potential as a powerful and sustainable oxidant for marine resource processing.

Conditions of metamorphism of the Outokumpu Cu - Co - Zn deposit from sphalerite geobarometry [PDF]
Bulletin of the Geological Society of Finland, 1998 Electron microprobe analysis was used to determine Zn and Fe in homogeneous samples of sphalerite in mutual contact with pyrrhotite and pyrite from the disseminated ore layer stratigraphically high in the Keretti orebody at Outokumpu, Finland.

Two-Stage Oxidative Leaching of Low-Grade Copper–Zinc Sulfide Concentrate
Microorganisms, 2022 Bioleaching may be effectively used to extract nonferrous metals from sulfide ores and concentrates. At the same time, some minerals are refractory and their bioleaching rate is often comparatively low that does not allow the required metal extraction ...
