Lattice Dynamics of Rutile Germanium Dioxide (r‐GeO2)
Advanced Electronic Materials, EarlyView.The rutile polymorph of GeO2 is a promising ultra‐wide bandgap material, but key properties for its technological exploitation remain poorly understood. Using polarization angle‐resolved Raman spectroscopy, we resolve long‐standing uncertainties in the energies of Raman‐active phonons and extract relative Raman tensor elements.

Between Order and Confusion: Clearing up Structural Misconceptions in Carbon Materials Nomenclature
Angewandte Chemie International Edition, EarlyView.Despite the versatile use of carbon materials, inconsistent terminology and inadequate characterization – especially regarding graphene structures based on sp2‐hybridized carbon atoms – often cause confusion. This perspective clarifies terms like graphite, graphitic carbon, non‐graphitic carbon, and amorphous carbon by aligning IUPAC definitions with X‐

Carbon Energy, EarlyView.Defect engineering anchors near‐zero‐valent Pt single atoms at oxygen vacancies of TiO2, forming distinctive Pt–Ti coordination that regulates electron density and optimizes hydrogen adsorption. The vacancy‐induced metal‐support interaction facilitates efficient electron transfer and accelerates water dissociation, enabling pH‐universal hydrogen ...

Contributions to Plasma Physics, EarlyView.ABSTRACT The properties of plasmas in the low‐density limit are described by virial expansions. Analytical expressions are known for the lowest virial coefficients from Green's function approaches. Recently, accurate path‐integral Monte Carlo (PIMC) simulations were performed for the hydrogen plasma at low densities by Filinov and Bonitz (Phys. Rev.
