Melting of B12P2 boron subphosphide under pressure

open access: yes, 2016
Melting of boron subphosphide (B12P2) to 26 GPa has been studied by in situ synchrotron X-ray powder diffraction in a laser-heated diamond anvil cell, and by quenching and electrical resistance measurements in a toroid-type high-pressure apparatus. B12P2

Irrigation Monitoring With Cosmic‐Ray Neutron Sensors: Unraveling Field Experiments With Neutron Transport Simulations

open access: yesWater Resources Research, Volume 62, Issue 3, March 2026.
Abstract Irrigation is essential for stabilizing yields and sustaining food production, yet it faces increasing challenges, especially in water‐scarce regions. Cosmic‐ray neutron sensors (CRNS) are a promising tool in irrigation management as they can continuously monitor soil water content (SWC) over large areas.

Thermodynamic aspects of materials' hardness: prediction of novel superhard high-pressure phases

open access: yes, 2011
In the present work we have proposed the method that allows one to easily estimate hardness and bulk modulus of known or hypothetical solid phases from the data on Gibbs energy of atomization of the elements and corresponding covalent radii.

Predicting the Thermal Conductivity of Porous SiC Ceramics by Machine Learning With Novel Encoding

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 3, March 2026.
Thermal‐conductivity prediction of porous SiC ceramics is modeled using a molecular‐weight encoding of sintering additives, achieving accuracy comparable to label encoding while preserving scientific meaning. Porosity consistently emerges as the primary influential parameter when predicting thermal conductivity.
