Bent colloidal rods exhibit fascinating polar ordering and chirality formation despite the achiral nature of the rods.
Bent-core liquid crystal (LC) molecules are known to form mesophases with fascinating polar order and supramolecular chirality

Objective Test the hypothesis that glass-bonding of free-form veneer and core ceramic layers can produce robust interfaces, chemically durable and esthetic in appearance and, above all, resistant to delamination. Methods Layers of independently produ

Development of new joining glasses tailored to layered all-ceramic dental restoration systems is described. These new glasses were developed to meet the requirements for dental restorations, including coefficient of thermal expansion (CTE) matching i

Nanoindentation and the viscous-elastic–plastic (VEP) model developed by Oyen and Cook for lightly filled thermoplastic polymer composites were used to characterize the elastic modulus, hardness, and viscoelastic response of a new high elastic modu

Joining a brittle veneer to a strong ceramic core with an adhesive offers potential benefits over current fabrication methods for all-ceramic crowns. We tested the hypothesis that such joining can withstand subsurface radial cracking in the veneer, f

Crack propagation across interlayers separating adjoining brittle plates in flexure was studied using a model glass/epoxy/glass system. A transverse starter crack in the center glass plate was made to propagate to the nearest epoxy interface, where i

A layer structure consisting of two glass plates bonded with polymer-based adhesives and loaded at the upper surface with a linewedge indenter is used to evaluate crack containment. Two adhesives are used, a low-modulus epoxy resin and a particle-fil

When both precious metal electrode and base metal electrode (BME) capacitors were subjected to autoclave (121 °C/100% RH) testing for 500 h, it was found that the precious metal capacitors aged according to a well known aging mechanism (average capa

Reliable and accurate temperature measurement during microwave processing of ceramic bodies is controversial. Although thermocouples are routinely used in conventional thermal furnaces, their presence in microwave furnaces can locally distort the ele
