Structural Changes and Transport Properties of YBa2Cu3O7 Locally Modified by a He+ Focused Ion Beam
Advanced Science, EarlyView.The structure and the electric transport properties of YBa2Cu3O7 modified with 30 keV He+${\rm He}^{+}$ ions depend on the irradiation dose and lateral size of the irradiated area, as shown by low‐temperature resistivity measurements, diffraction with a nanofocused X‐ray beam and atomic force microscopy.

Chelation‐Driven Dual‐Interface Regulation for Long‐Life Aqueous Zn–I2 Batteries
Advanced Science, EarlyView.Zn2+–TPEN coordination generates TPEN‐derived coordination species (TCC) that contribute to the regulation of both electrode interfaces. At the Zn anode, it creates an interfacial environment with reduced water accessibility that suppresses HER and corrosion while promoting uniform deposition; at the I2 cathode, it captures polyiodide to inhibit ...

Autonomous Solar Metallurgy for High‐Purity Gold Recovery from Electronic Waste
Advanced Science, EarlyView.Inspired by microbial strategies for metal uptake and biomineralization, defect‐rich copper sulfide (Cu31S16) functions as a solar metallurgical platform that unifies Au(III) capture, reduction, and self‐separation. The bioinspired design enables ultrafast gold recovery from electronic‐waste leachates and the spontaneous formation of millimeter‐scale ...
