Infinite Functional Versatility, Formidable Limits: Evaluating Gallium‐Based Liquid Metals in Rechargeable Batteries

Carbon Energy, EarlyView.
Beyond the hype surrounding the self‐healing properties of gallium‐based liquid metals (Ga‐LMs), this perspective critically examines their functional roles in metal‐ion batteries, highlighting both their underlying merits and the often‐overlooked challenges, including non‐representative design and testing configurations, performance overestimations ...

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.

Dual‐Mode Electrophoretic Displays Enabled by Quantum Dot‐Decorated PR48:2 Pigment Particles and TiO2 for All‐Weather Visibility, Excellent Bistability, and Enhanced Readability

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study presents a novel quantum dot electrophoretic display (QDEPD), which combines electro‐controlled reflection and optically‐triggered emission to achieve efficient multi‐modal switching within a single pixel. By incorporating multi‐component nanostructures, the system enhances functional integration and multi‐modal response capabilities.

Atomic‐Scale Structurally Locked 1T/2H‐MoS2/ZnS Z‐Scheme Heterojunctions for Prolonged Charge Kinetics and Dual‐Functional Photocatalysis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Atomic‐scale structurally locked 1T/2H‐MoS2/ZnS direct Z‐scheme heterojunction enabling dual‐functional photocatalysis. The metallic 1T‐MoS2 phase serves as an electronic actuator that bridges charge transfer across the heterointerface, resulting in prolonged charge kinetics, efficient hydrogen evolution, and complete degradation of Malachite Green ...

Replacement of Ores Recorded by Textures and Chemical Compositions of Sphalerite: An Example From the Furutobe Kuroko Deposit, Akita, Japan

Geological Journal, EarlyView.
Coupled dissolution‐reprecipitation of early formed Cd‐, Fe‐, Ag‐ and Sb‐poor sphalerite through interaction with high‐temperature and high‐sulphur fugacity Cu‐rich fluids, responsible for the formation of the yellow ores, resulted in the formation of Cd‐, Fe‐, Ag‐ and Sb‐rich, heavily chalcopyrite‐diseased sphalerite and enrichment of critical metals ...

On the Separation of Pyrrhotite and Sphalerite

FLOTATION, 1969
The depression of pyrrhotite containing sphalerite is very difficult on account of the copper ion activation during the zinc flotation process. Accordingly, the mineral particles to be floated by the copper ion activation are so many that the flotation machine overloads.

Ferromagnetism in sphalerite and wurtzite CdS nanostructures [PDF]

Nanoscale Research Letters, 2013
Abstract Room-temperature ferromagnetism is observed in undoped sphalerite and wurtzite CdS nanostructures which are synthesized by hydrothermal methods. Scanning electron microscopy and transmission electron microscopy results indicate that the sphalerite CdS samples show a spherical-like shape and the wurtzite CdS ones show a flower-like ...
