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 ...

Defects‐Triggered In Situ Reconstruction in Metal‐Halide Perovskites for Photo‐Rechargeable Lithium‐Ion Batteries

Interdisciplinary Materials, EarlyView.
This work presents a strategy for the in situ formation of heterostructures in bifunctional photoelectrodes for photo‐rechargeable lithium‐ion batteries (PRLIBs). Defect‐driven reconstruction in metal‐halide perovskites (MHP) activates Cu+/Cu2+ leaching from the current collector, thereby enabling the in situ formation of CuO/CuI‐MHP heterojunctions ...

Turmeric essential oil‐loaded wheat starch cryogels as superabsorbent pads for active packaging of fish fillets

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND This study aimed to create a cryogel with water‐absorbing and antioxidant properties. Wheat starch (10%, w/v) was used to produce cryogels, which were then incorporated with turmeric essential oil (TEO) at two concentrations: 20% and 30% (w/w of starch).

Effect of pyrrhotite on gold leaching

The recovery of gold from its ores by cyanide leaching has been practiced around the world for more than a century. One of the parameters that dictate the rate of gold leaching as well as the rate of reagent consumption (lime and cyanide) is the ...
