Exploring New Chemical Paths in Quantum AI: Preliminary Accomplishments and Future Perspectives

Advanced Quantum Technologies, EarlyView.
Two new strategies derived from Chemical AI to promote the advancement of sustainable quantum technologies are presented and discussed. The first strategy relies on the chemical implementation of molecular fuzzy sets, which are quantum mixed states associated with chemical microheterogeneous systems. The second strategy relies on photochromic compounds

Dual‐Stage Heat Treatment for Enhanced Hydrogen Storage Properties of Mg−Ni−Y Alloys

Rare Metals, EarlyView.
ABSTRACT Mg−Ni−Y alloy is considered to be one of the most promising hydrogen storage materials, but its high dehydrogenation energy barrier hinders its practical application. A dual‐stage heat treatment (490°C × 4 h + 550°C × 4 h) is applied to optimize the microstructure and hydrogen storage performance of a vacuum‐melted Mg94Ni3Y3 alloy.

Hierarchical Strengthening Design in AlCrCuFeNi2.5/CuCrZr Composites Enables Strength–Ductility–Conductivity Synergy

Rare Metals, EarlyView.
ABSTRACT Developing Cu‐based composites that simultaneously achieve ultra‐high strength, ductility, and electrical conductivity remains critical for advanced electrical contact applications. In this work, multiphase AlCrCuFeNi2.5 high‐entropy alloy (HEA) reinforcements are incorporated into CuCrZr matrix via spark plasma sintering (SPS) and annealing ...

Current Control Methods for an Asymmetrical Six-Phase Induction Motor Drive [PDF]

Using the vector space decomposition approach, the currents in a multiphase machine with distributed winding can be decoupled into the flux and torque producing α-β components, and the loss-producing x-y and zero-sequence components. While the control of

Recycling‐Induced Copper Contamination of a 42CrMo4 Quench and Tempering Steel—Scaling and Susceptibility to Hot Shortness

steel research international, EarlyView.
In this study, the susceptibility to copper‐induced hot shortness of the alloy 42CrMo4 is investigated by different hot tensile tests, as well as by a detailed analysis of the formed oxidation products. While an enrichment of metallic copper and a penetration of the grain boundaries are observed, no critical reduction of the tensile test properties can
