Optically transparent ceramics by spark plasma sintering of oxide nanoparticles [PDF]

, 2010
Optical transparency in polycrystalline ceramic oxides can be achieved if the material is fully densified. Spark plasma sintering (SPS) of oxide nanoparticles leads to immediate densification with final-stage sintering.

Achieving Large and Anisotropic Spin‐Mediated Thermal Transport in Textured Quantum Magnets

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
An advanced solvent‐cast cold pressing method is developed to synthesize highly textured quantum magnets. By aligning spin chains in Ca2CuO3 perpendicular to the pressing direction, a spin‐mediated thermal conductivity of 10 ± 1 W m⁻¹ K⁻¹ is achieved, the highest reported for polycrystalline quantum materials.
