Geological Journal, EarlyView.The composition of intrusive rocks suggests that the magma was likely generated in a subduction‐related setting. The arc crustal thickness in the Phnom Sro Ngam and Halo Prospects was probably < 40 km during emplacement. Zircon U–Pb age range indicates a correlation with Loei Fold Belt magmatic activity.

Heavy‐Metal‐Free Colloidal Quantum Dots for Photocatalysis
Small, EarlyView.Heavy‐metal‐free colloidal quantum dots provide sustainable photocatalytic platforms by combining tunable band structures, strong light absorption, and programmable surfaces/interfaces. This Review highlights how core/shell engineering, alloying, defect regulation, ligand design, and hybrid‐interface construction direct charge separation and ...

Journal of Metamorphic Geology, EarlyView.ABSTRACT Reconstructing the pressure–temperature–time (P–T–t) evolution of (ultra)high‐pressure rocks is essential for constraining subduction and collisional dynamics. Subduction zones are often investigated using basic eclogites, whereas nonbasic high‐pressure rocks remain comparatively understudied, potentially hindering a comprehensive ...

Meteoritics &Planetary Science, EarlyView.Abstract Here we report on the microstructure and chemistry of sulfide minerals returned from asteroid (162173) Ryugu. We identify a unique sulfide population in particle A0016 composed of violarite (FeNi2S4), pyrite (FeS2), chalcopyrite (CuFeS2), pyrrhotite (Fe1‐xS), and pentlandite ([Fe,Ni]9S8).

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 9, Page 1146-1158, September 2026.This work demonstrates progress in the development of wide‐bandgap CIGS solar cells featuring a transparent back contact, for the application of top cell in tandem devices. A semitransparent device with a bandgap of 1.6 eV achieved a power conversion efficiency of nearly 13% on an ITO back contact.

Advanced Science, Volume 13, Issue 43, 3 August 2026.This study first extends the high‐entropy concept to I‐III‐VI quantum dots (QDs) and synthesizes CZCrGSe/ZnSe/ZnS core/shell/shell QDs with a record photoluminescence quantum yield (PLQY) of 100%. Their ZnSe/ZnS double shell efficiently passivates defects and boosts structural stability.

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 ...
