physica status solidi (RRL) – Rapid Research Letters, EarlyView.A new parameterization of Si and Ge in the framework of the extended Hückel theory is presented. Bandgap and effective mass are calculated for unstrained and biaxially strained SiGe alloys. In SiGeC alloys with C atoms in close proximity, additional bands are observed, which are related to defect states in real crystals.

Orbitally Driven Anomalous Thermal Transport Under High Pressure in Gallium Nitride
Rare Metals, EarlyView.ABSTRACT Extreme conditions such as high pressure offer opportunities for innovative materials design and applications. For over a century, studies on thermal transport in crystals under high hydrostatic pressure have shown that lattice thermal conductivity generally exhibits a monotonic increase with pressure.

Rare Metals, EarlyView.ABSTRACT TiFe‐based hydrogen storage alloys have garnered significant attention because of their cost‐effectiveness, high hydrogen capacity, and favorable hydrogen absorption/desorption characteristics. However, practical application was limited by activation challenges and sensitivity to environmental poisoning.

Charge Transport Across Single Molecules at the Metal–Superconductor Interface
Small, EarlyView.The evolution of Andreev reflection in single‐molecule junctions is probed with the decreasing distance between a normal‐metal tip and a conventional superconductor. Andreev reflection becomes most effective when a molecular orbital straddles the Fermi level.

Untangling the Mechanisms in Magneto‐Electrocatalytic Oxygen Evolution
Small, EarlyView.Magnetic fields can enhance the oxygen evolution reaction in electrocatalytic water‐splitting for green‐H2. Yet, commercialization cannot be realized until the underlying magneto‐electric mechanisms are understood. This work uses reactor orientation to untangle these mechanisms. Lorentz force is shown to control metallic plates, while spin‐polarization

Correlation‐Driven d‐Band Modifications Promote Chemical Bonding at 3d‐Ferromagnetic Surfaces
Small, EarlyView.Electron correlation at the oxygen‐passivated Fe(100) surface renormalizes and narrows the Fe d‐bands, enhancing their energetic overlap with the frontier orbitals of adsorbed pentacene. This strengthens hybridization and converts a weakly bound interface into a chemisorbed hybrid system, illustrating how correlation‐tuned d‐bands can be used to ...

Tunable Colloidal Synthesis Enabling μ‐ARPES on Individual Bismuth Nanocrystals
Small, EarlyView.We report a highly controlled colloidal synthesis of Bi nanosheets with tunable lateral sizes (0.6–4.1 µm), hexagonal shape, and a layered single‐crystalline structure along the {00l} planes. The nanosheets feature high phase purity and excellent ambient stability. Remarkably, O2 promotes larger lateral growth with ultra‐smooth surfaces. This scalable,

Small, EarlyView.Thiol‐free hot injection approach yields quasi‐2D klockmannite CuSe nanocrystals, specifically nanosheets and uniform triangular nanoplatelets. This study reconsiders the klockmannite from the point of view of crystal anisotropy and demonstrates its effect on plasmonic response in the near‐infrared spectral region with the theoretical emergence of ...

Small Structures, EarlyView.Flexoelectric polarization is harnessed to dynamically enhance phosphatase‐mimicking catalysis in Gd‐based nanoflowers, enabling ultrasound‐responsive and efficient biophosphate ester hydrolysis through strain‐induced electronic modulation. Phosphatase‐mimicking nanozymes provide highly stable enzyme‐like activity but remain limited by their static ...
