new ceramic line. The new ceramic formulation was released in 2005 under the brand of IPS e.Max Press [5]. Ultimately the introduction of the e.Max line would lead to the discontinuation of the Empress 2 line in 2009 [6]. With the advent of digital dentistry and advances in computer-aided design and computer-aided manufacturing

Sep 12, 2014· Ceramics are strong and stiff, but their limited ability to stretch like putty or steels makes them unsuitable for many engineering applications. Meza et al. constructed ceramic nanolattices from aluminum oxide, in which the beams are designed to stretch rather than bend. A key parameter in lattice design is the ratio of the wall thickness to the beam radius.

transformation of ceramic nanofiber textiles from insulation to conduction at room temperature. After putting dimethylacetamide-wetted textiles, including TiO 2, SnO 2, BaTiO 3, and Li 0.33La 0.56TiO 3, on lithium plates, the self-driven chemical reactions induce defects in oxides. These defects initiate an interfacial insulation-to-conductive
