Multi-functional Ceramic Composites of Boron Nitride
Hall-effect thrusters used in electric propulsion systems have historically required a dielectric such as hexagonal boron nitride (h-BN) that has good thermal emissivity, is chemically inert and is resistant to thermal shock. However, the brittle nature of bulk BN poses challenges under dynamic loads, such as the launch environment, where the stiff material is subject to vibration and strain that can lead to catastrophic failures.

Reverse Engineering Lusterware Porcelain
Meissen porcelain was Europe’s first successful replication of Chinese porcelain with decorative over-glaze enamels, invented by Johann Böttger in the early 18th century. A full pallet of colors was desired to replicate Chinese ceramics during the Böttger period of the Meissen factory’s production. While this goal was not realized for years to come, rare “mother of pearl” and lustrous purple glazes were produced by applying gold nanoparticles to the top glaze. Read More...
