The choice of appropriate definitive restoration endodontically treated teeth should be guided by the amount remaining hard tissues as well functional and aesthetic considerations. Post and-core materials with biomechanical properties similar to dentin could also advantageous in reducing risk root fractures. high performance polymer Poly-ether-ether-ketone (PEEK) is an example one such type mat...

The family of semi-crystalline, aromatic, high-temperature thermoplastics known as poly(ether-ketone)s are insoluble in conventional organic solvents, but undergo completely general and quantitatively reversible reactions with alkanedithiols in strong acid media, to give soluble poly(dithioacetal)s, which are readily characterisable by GPC and light scattering techniques.

Orthopedic implant infections have been steadily increasing while, at the same time, antibiotics developed to kill such bacteria have proven less and less effective with every passing day. It is clear that new approaches that do not rely on the use of antibiotics are needed to decrease medical device infections. Inspired by cicada wing surface topographical features, nanostructured surfaces rep...

High energy density, high temperature, and low loss dielectric polymers have drawn increasing attention in research owing to their potential applications power electronic pulsed devices. In this study, a new class of organo-soluble dipolar glass (DGPs) are synthesized via polycondensation post-functionalization poly(aryl ether)s (PAEs) based on phenolphthalin. Due the nonplanar backbone structu...
