Pt Sub‐Nanoclusters on ZIF‐Derived Ultrafine CdxZn1−xS Solid Solution: High‐Performance Photoreforming Lactic Acid to H2 and Value‐Added Chemicals

open access: yesElectron, EarlyView.
This work presents ZIF‐derived ultrafine CdxZn1−xS decorated with Pt sub‐nanoclusters for efficient photocatalytic reforming of lactic acid. The catalyst achieves high H2 evolution (270.6 mmol h−1 g−1) and selective pyruvic acid production (73.1%), with mechanistic insights revealing Pt‐mediated control over reaction pathways.

The Black‐Box of ESG Scores From Rating Agencies: Do They Genuinely Reflect Sustainability Practices, or Are They Disproportionately Shaped by Financial Performance?

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT This study examines the environmental, social and governance (ESG) scoring methodologies used by Bloomberg and S&P Global through the lens of Data Envelopment Analysis (DEA). It addresses a notable gap in the literature by identifying the underlying factors that shape ESG scores and providing practical insights for companies seeking to ...

Raman Spectroscopic Analysis and In Situ Heating Experiments on Adranosite Minerals

open access: yesJournal of Raman Spectroscopy, EarlyView.
This study provides the first detailed Raman spectroscopic characterization of rare ammonium sulfates adranosite, iron‐rich adranosite, and adranosite‐(Fe) from volcanic and coal‐fire environments. Distinct spectral features reveal compositional differences and structural effects of Fe substitution.

Tailoring SHG Efficiency via t‐Te Nanocrystals in Tellurite Glasses by Femtosecond Laser Micromachining

open access: yesLaser &Photonics Reviews, EarlyView.
Femtosecond laser irradiation at the glass surface induces symmetry breaking and crystallization of triclínic t‐Te nanophases, enabling intense second‐harmonic generation (SHG). The illustration depicts the fs‐pulse interaction, structural rearrangement, and nonlinear activation from amorphous tellurite glass to crystalline regions.

Molecular Dynamics Study of Melt Structure and Transport Properties of Mg‒Al Alloy

open access: yesMaterials Genome Engineering Advances, EarlyView.
The structural evolution and transport coefficients of the Mg‐Al alloy melt at different temperatures were investigated using molecular dynamics simulation methods. By establishing relationships among structure, diffusion, and viscosity, the microscopic mechanisms behind the temperature‐induced changes in transport properties are revealed. ABSTRACT The
