Defect Engineering in Large‐Scale CVD‐Grown Hexagonal Boron Nitride: Formation, Spectroscopy, and Spin Relaxation Dynamics

Small, EarlyView.
The controlled formation of defects in large‐area CVD‐grown hBN using various irradiation methods is demonstrated. Defect type and properties depend on particle type (He+, Ne+, Ar+, neutrons, and electrons), substrate effects, and film thickness.

In Situ and Operando Analytical Techniques of Single‐Atom Catalysts for Electrocatalytic CO2 Reduction

Small Methods, EarlyView.
Single‐atom catalysts (SACs) exhibit significant potential in CO2 reduction reactions (CO2RR) due to their unique geometric and electronic configurations. In situ and operando analytical techniques are essential for understanding CO2RR mechanisms and designing effective catalysts.

Exploring entropic contributions of modifier cations in supercooled liquids through isotopic substitution

Journal of the American Ceramic Society, Volume 108, Issue 12, December 2025.
Evolution of excess entropy of 7(6)LiPO3 supercooled liquid (SCL) between Tg and Tm Abstract The vibrational and configurational entropic contributions of modifier Li cations to the glass‐to‐liquid transition and the fragility of supercooled (Li,Na)PO3 liquids are investigated using calorimetric measurements of their ⁷Li and ⁶Li isotopologues ...

The Reduction of Group 6–8 Transition Metal Oxides with Hydrogen—From Ore Smelting to Reaction Pathways#

European Journal of Inorganic Chemistry, Volume 28, Issue 30, October 22, 2025.
As the reduction of transition metal oxides by coal poses a significant climate risk, the use of alternative reducing agents such as hydrogen is becoming increasingly important. This review summarizes the current knowledge of the reduction pathways of transition metal oxides from groups 6 to 8.

Magnetic excitation in the hyperkagome antiferromagnet Mn_{3}RhSi

Physical Review Research
In a paramagnetic state of a hyperkagome lattice antiferromagnet Mn_{3}RhSi, magnetic diffuse scattering by magnetic short-range order is observed over a wide temperature range of approximately 500 K above the Néel temperature of 190 K.

A comparative study of clinically used fast Monte Carlo dose engines for proton therapy

Journal of Applied Clinical Medical Physics, Volume 26, Issue 10, October 2025.
Abstract Background Several fast Monte Carlo (MC) codes have been implemented and used to simulate proton transport and calculate patient doses in proton therapy. The resulting dose is typically compared to full MC codes, rather than other fast MC codes.

Compression‐Induced Amorphization of ZIF‐62 Leading to Formation of Porous Glass: Overcoming the Limitations of Current Methods

Chemistry–Methods, Volume 5, Issue 10, October 2025.
Nonhydrostatic compression in steps is applied to transform crystalline zeolitic imidazolate framework‐62 into glass at room temperature. This method overcomes the limitations of existing approaches. This research reveals the mechanism of this phase transformation, including modifications in porosity, using various techniques, particularly positron ...
