In Situ Graded Ceramic/Reduced Graphene Oxide Composites Manufactured by Spark Plasma Sintering

open access: yesCeramics, 2020
The present work merges two key strategies for the manufacturing of advanced ceramics, in particular, the development of functionally graded materials (FGMs) and the addition of graphene-based fillers into a ceramic matrix.

Nanocrystallization in Fluorochlorozirconate Glass‐Ceramics [PDF]

open access: yesJournal of the American Ceramic Society, 2013
Heat treating fluorochlorozirconate ( FCZ ) glasses nucleates nanocrystals in the glass matrix, resulting in a nanocomposite glass‐ceramic that has optical properties suitable for use as a medical imaging plate. Understanding the way in which the nanocrystal nucleation proceeds is critical to

Clinical Effect of Feldspar Glass Ceramics and Lithium Disilicate Reinforced Glass Ceramics

open access: yesContrast Media & Molecular Imaging, 2022
The clinical effect of feldspar ceramics and lithium disilicate reinforced glass ceramics was studied. 57 affected teeth with complete root canal treatment and computer aided design/computer aided manufacturing (CAD/CAM) endocrown restoration were reviewed 24‐36 months aftercompletion of the restoration. These dimensions including anatomical morphology,
