X‐Ray Photoelectron Spectroscopy as Useful Technique for the Quantification of Halogen and Chalcogen Bonding Interactions

ChemistryEurope, EarlyView.
Unprecedented application of X‐ray photoelectron spectroscopy (XPS) for quantifying halogen and chalcogen bond strengths. This pioneering work provides the first benchmark study and establishes strong correlations between XPS shifts (ΔBE) and interaction energies (ΔE), revealing XPS as an experimental measure for noncovalent bond quantification in ...

Insight Into the Failure Mechanism of Conversion‐Alloy Anode Materials in Potassium‐Ion Batteries: A Case Study of Bi2Te3

Carbon Energy, EarlyView.
Through combining electrochemical profiles with multi‐scale microscopies, spectroscopy, and theoretical calculations, the failure processes and mechanisms of Bi2Te3 are identified into two stages: (1) the shuttle effect, dominating the first stage, results in the rapid capacity fading in the first several cycles and (2) the SEI accumulation, dominating

Simple Access to a Series of Higher Substituted Pentafluoroorthotellurate‐Based Silanes

Chemistry – A European Journal, EarlyView.
The pentafluoroorthotellurate ligand was introduced to organo silanes. A variety of silanes with the formular RxSi(OTeF5)4–x were synthesized and characterized via spectroscopic techniques and sc‐XRD. The influence of the number of OTeF5 groups on structural properties as well as the fluoride ion affinities (FIA) has been studied and compared to other ...

Stepwise Optimization of Thermoelectric Performance in Cu3SbSe4‐Based Compounds via Alloying and Hierarchical Structuring

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Under the stepwise optimization strategy, (Sn, Te) co‐alloying functions as the primary initiative to enhance the power factor (PF), while the subsequent incorporation of AgCuTe operates as a synergistic maneuver to suppress lattice thermal conductivity (κlat), thereby concomitantly boosting the dimensionless figure of merit (ZT).

Lymphoma, multiple myeloma and leukaemia incidence in regions of Belarus most heavily contaminated by the Chernobyl accident

International Journal of Cancer, EarlyView.
What's New? The 1986 Chernobyl accident led to widespread radioactive contamination across parts of Europe, with elevated childhood leukaemia rates observed in heavily affected areas of Ukraine. Data on long‐term haematological and other non‐thyroid cancer risk in the general population in heavily contaminated regions, however, remain limited.

Nano‐Raman Spectroscopy of Tellurium Nanowires

Journal of Raman Spectroscopy, EarlyView.
Nano‐Raman evidences a diameter dependence of the peak position, among different tellurium nanowires and along the single species. ABSTRACT Tellurium‐based nanowires are interesting structures for applications in low‐dimensional electronics. This work investigates the vibrational dynamics of trigonal tellurium (t‐Te) nanowires through tip‐enhanced ...

Unravelling the Spatiotemporal Exciton Dynamics in Electrically Pumped Organic Laser Diodes

Laser &Photonics Reviews, EarlyView.
High‐speed OLED measurements combined with advanced simulations reveal how singlet, triplet, and polaron dynamics drive key loss channels that hinder organic semiconductor lasing, while presenting strategies to overcome them. Abstract Organic materials offer wide‐band emission covering regions of the spectrum unachievable by conventional semiconductors.

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

Laser &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.

Two‐Dimensional Transition Metal Dichalcogenides Properties Enhanced by Nano‐ and Micro‐Scale Shape Control

MetalMat, EarlyView.
This review explores current strategies for shaping two‐dimensional transition metal dichalcogenides (TMDs) beyond their planar form. It highlights how strain engineering, nanopatterning, and growth on complex substrates modulate their mechanical, optical, and electronic properties.
