Mechanical and Dielectric Properties of Porous Slip Cast Silicon Nitride: Yttrium Oxide‐Aluminum Oxide Sintering Aids

open access: yesInternational Journal of Applied Ceramic Technology, Volume 23, Issue 2, April 2026.
Silicon nitride samples were slip cast using yttrium oxide‐aluminum sintering aids to fabricate porous materials for radar frequency windows. Microstructure and phase composition were determined. Flexural strength, elastic modulus, dielectric constant, and loss tangent were collected from room temperature to elevated temperatures up to 1200°C.

Molecular Dynamics in Tetrafluoridoborate Salts of Divalent Metals Studied by Nuclear Magnetic Resonance Spectroscopy

open access: yesChemPhysChem, Volume 27, Issue 5, 13 March 2026.
We studied molecular dynamics in four tetrafluoridoborate salts by means of nuclear magnetic resonance. Characteristical motions in these systems are thermally‐activated reorientations of BF4− ions. We determine the activation energies for these processes and compare the dynamics with those in borohydride systems that share the tetrahedral geometry of ...

Understanding Decoherence of the Boron Vacancy Center in Hexagonal Boron Nitride

open access: yesAdvanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
State‐of‐the‐art computations unravel the intricate decoherence dynamics of the boron vacancy center in hexagonal boron nitride across magnetic fields from 0 to 3 T. Five distinct regimes emerge, dominated by nuclear spin interactions, revealing optimal coherence times of 1–20 µs in the 180–350 mT range for isotopically pure samples.
