Small Structures, Volume 7, Issue 2, February 2026.Local Ag substitution in diamond‐like Cu2‐xAgxIn2Se4 induces dynamic off‐centering distortions that strongly scatter phonons while preserving high carrier mobility. The resulting interplay between alloy disorder and band structure yields ultralow lattice thermal conductivity and promising thermoelectric performance in this sustainable, tellurium‐free ...

Study of the Electrochemical Passive-Active Transition of Chalcopyrite in Acidic Solution
International Journal of Electrochemical Science, 2016 The electrochemical behaviors of chalcopyrite in 1.0 M H2SO4 were studied by potentiodynamic polarization. The experimental results revealed that chalcopyrite has four different potential ranges: passive for OCP up to 500 mV; trans-passive dissolution ...

Rapid terrestrial weathering of the CI1 carbonaceous chondrite find Oued Chebeika 002
Meteoritics &Planetary Science, Volume 61, Issue 2, Page 211-223, February 2026.Abstract Alteration of historic CI1 meteorite falls during their curation demonstrates the susceptibility of smectite‐rich carbonaceous chondrites to terrestrial exposure. The discovery of Oued Chebeika 002 in Morocco in June 2024 presents a unique opportunity to document the earliest stages of weathering of a CI1 find.

International Journal of Mining Science and TechnologyA novel small molecule depressant (M-DEP) was used to separate chalcopyrite and molybdenite via flotation. The results showed that M-DEP had an excellent selective depression on molybdenite, while had little effect on the flotation of chalcopyrite.
