Spectrophotometric analyses on electronic structures of glide dislocation cores in ZnS

Journal of the American Ceramic Society, Volume 108, Issue 6, June 2025.
Abstract It has been reported that dislocations in ZnS can trap photoexcited carriers and then undergo core reconstruction. However, electronic states of the trapped carriers at the reconstructed dislocations were not detected experimentally.

Geochemical and mineralogical features of the polymetallic deposit from Ali' (NE Sicily, Italy)

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2007
The mineralization processes in the Peloritani Belt (Southern Sector of the Calabria- Peloritani Arc), related to Pre-Variscan intracontinental rifting, produced sedex-type Pb, Zn, F (Ag), Cu, W (As, Sb) ores.

Improved Facet and Edge Passivation in Near‐Infrared III‐V Colloidal Quantum Dot Photodetectors

Advanced Materials, Volume 37, Issue 18, May 5, 2025.
Increasing InAs CQD size exposes diverse facets and edges, bringing challenges for effective passivation. This work introduces a mixed‐halide passivation strategy to stabilize these facets and edges, doubling anti‐oxidation ability and boosting mobility.

A Comparison of the Electrochemical Oxidative Dissolution of Pyrite and Chalcopyrite in Dilute Nitric Acid Solution

ChemistryOpen, Volume 14, Issue 5, May 2025.
This research was primarily driven by the aim to extract residual encapsulated gold in sulfidic minerals, which would require the dissolution of the mineral. The electrochemical oxidation of pyrite and chalcopyrite in 0.5 M nitric acid was investigated here, using cyclic voltammetry and electrochemical impedance spectroscopy, to see if there are any ...

The Anchimetamorphic Tectonic Mélange of Tempa Roccarossa (Southern Apennines, Italy): Insights on the Kinematic and Thermobaric Evolution of the Upper Miocene‐Pliocene Orogenic Wedge

Tectonics, Volume 44, Issue 5, May 2025.
Abstract Studies of tectonic mélanges provide constraints on the evolution of active plate margins. However, resolving the pressure‐temperature trajectories of these deformed rocks, which are exhumed from low‐temperature conditions, can be challenging.
