PURPOSE The aim of this in vitro study was to investigate the fracture resistance under chewing simulation of implant-supported posterior restorations (crowns cemented to hybrid-abutments) made of different all-ceramic materials. MATERIALS AND METHODS Monolithic zirconia (MZr) and monolithic lithium disilicate (MLD) crowns for mandibular first molar were fabricated using computer-aided design...

We have studied the mechanical properties of monolithic bulk metallic glasses and composite in the La based alloys. La86-yAl14(Cu, Ni)y (y=24 to 32) alloy systems was used to cast the in-situ structure and subsequently tested under compression. We found that the ductility of the monolithic is actually poorer than that of the fully crystalline composite.

A monolithic diamond Raman laser is reported. It utilizes a 13-mm radius of curvature lens etched onto the diamond surface and dielectric mirror coatings to form a stable resonator. The performance is compared to that of a monolithic diamond Raman laser operating in a plane-plane cavity. On pumping with a compact Q-switched laser at 532 nm (16 μJ pulse energy; 1.5 ns pulse duration; 10 kHz repe...

A chip-scale, highly-reconfigurable transmitter and receiver, which hetero-integrates Northrop Grumman’s novel phase-change switch (PCS) technology with commercial SiGe BiCMOS using 3Dstacking has been demonstrated. Further miniaturization and performance improvements are being pursued through fully monolithic integration. The current state of the technology will be discussed followed by a disc...

For a compact space $K$ we consider the $P(K)$ of probability regular Borel measures on $K$, equipped with weak$^\ast $ topology inherited from $C(K)^\ast $. We discuss possible characterizations those spaces for which is

We demonstrate the integration of a droplet-based microfluidic device with high performance liquid chromatography (HPLC) in a monolithic format. Sequential operations of separation, compartmentalisation and concentration counter were conducted on a monolithic chip. This describes the use of droplet-based microfluidics for the preservation of chromatographic separations, and its potential applic...

PURPOSE The purpose of this in vitro research project was to evaluate and compare the wear behavior of human tooth enamel opposing monolithic zirconia and other different ceramic restorative materials and also to observe the tetragonal to monoclinic phase transformation in zirconia-based ceramics that may occur while simulating wear occurring at room temperature in a wet environment.
