Ultrahigh thermal conductivity in isotope-enriched cubic boron nitride

open access: yes, 2020
Materials with high thermal conductivity (k) are of technological importance and fundamental interest. We grew cubic boron nitride (cBN) crystals with controlled abundance of boron isotopes and measured k greater than 1600 watts per meter-kelvin at room ...

Room temperature synthesis of cubic boron nitride films by pulse high energy density plasma

open access: yes, 1995
Cubic boron nitride films have been prepared on the Si(100) oriented substrate at room temperature by a pulse high energy density plasma (PHEDP). The pulse plasma is generated in a coaxial plasma gun. The working gas was a mixture of 50%B2H6 + 50%N2. The

High‐Pressure Synthesis and Chemical Bonding of Mg3BiN

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
The anti‐perovskite Mg3BiN is obtained by high‐pressure high‐temperature reaction of Mg–Bi mixture with boron nitride serving as crucible material. The compound is electron precise with essentially ionic bonding, and DOS calculations indicate semiconducting behavior.

On the Conservatisms of Nepheline Predictors for Canister Centerline Cooled (CCC) High‐Level Waste (HLW) Glasses

open access: yesInternational Journal of Applied Glass Science, Volume 17, Issue 3, July 2026.
ABSTRACT Multiple models and feature sets have been generated, which attempt to predict the crystallization of nepheline (NaAlSiO4) in high‐level radioactive waste (HLW) glasses under canister centerline cooling (CCC) conditions. Earlier models were found to be overly conservative, while newer models had a not insignificant rate of false positives and ...
