Phase Transformation‐Assisted Nucleation and Growth of a Single‐Phase FeCoNiCuNb Alloy
Advanced Science, EarlyView.The multi‐component crystal nucleus transitions between crystalline and amorphous states, generating vacancies that facilitate the incorporation of refractory elements. This process enables the formation of refractory high‐entropy alloys. Abstract High‐entropy alloys utilize high configurational entropy to stabilize solid solutions, suppress ...

Burn‐Safe Biodegradable Magnetocaloric Composites for Temperature‐Controlled Biomedical Applications
Advanced Science, EarlyView.This work investigates a magnetocaloric (Mn,Fe)2(P,Si) compound tailored for precise, self‐regulating heating in biomedical use. With a Curie temperature tuned at 43 °C, it enables therapeutic activation without overheating. Encapsulation in a composite ensures controlled temperature rise under an alternating magnetic field (AMF), with high ...

Advanced Science, EarlyView.This work leverages the level of carbon supersaturation in the metallic constituents during particle formation to regulate nanoparticle morphology, structure, and composition distribution. The solvent‐dependent (C/(C+O)) ratio and the relative kinetics of the competing reactions of carbon shell formation, coalescence of metallic constituents, and ...

Advanced Science, EarlyView.Molybdenum (Mo), with its unique strength, uniform corrosion, and radiopacity, enables innovative biodegradable implants for transformative stroke therapy. Abstract Neurovascular implants for stroke intervention face a critical dilemma: permanent devices (e.g., nitinol stents, platinum coils) often trigger chronic inflammation and recurrence, whereas ...
