Comparison of osteogenic potential of poly-ether-ether-ketone with titanium-coated poly-ether-ether-ketone and titanium-blended poly-ether-ether-ketone: An in vitro study
STATEMENT OF PROBLEM Poly-ether-ether-ketone (PEEK), a high-performance semi-crystalline thermoplastic polymer, has been employed to replace the metallic implant components in orthopedics. There were various studies performed in accordance to medical grade PEEK, but the relationship between titanium dioxide (TiO2)-coated PEEK, TiO2-blended PEEK, and untreated PEEK still remains complicated, eve...
متن کاملPoly (Ether Ether Ketone) Based Anion Exchange Membrane for Solid Alkaline Fuel Cell: A Review
Solid alkaline fuel cell is employed by polymer anion exchange membrane (AEM) that is permeable to hydroxide ion. A number of polymers have been proposed for AEM which include polysulfone (PSF), poly (phenylene oxide) (PPO), and poly (ether ether ketone) (PEEK). The purpose of this paper was to conduct a critical review on the development of PEEK polymer as AEM, particu...

There are many applications which arise in telecommunications information processing in which it is useful, and often necessary, to create and access multiple hypothetical states. These might correspond to future states reeecting pending updates (such as customer service orders), or hypothetical alternative states that would arise in the exploration of diierent solutions to a given problem. In ...
متن کاملp-Chlorobenzyl Ether: A p-Methoxybenzyl Ether in Disguise.
In the chemistry of polyfunctionalized organic compounds, protecting groups that can undergo mild and selective cleavage while still being stable during the entire synthetic sequence are often required. In this work, we present a straightforward conversion of the robust p-chlorobenzyl ether into the more labile and well-described p-methoxybenzyl ether using palladium catalysis. This reaction wa...

We examined the meaning of living with HIV/AIDS among women in Lebanon. Ten women living with HIV/AIDS (WLWHA) described their experiences via semistructured in-depth interviews. They navigated a process of HIV diagnosis acceptance that incorporated six overlapping elements: receiving the news, accessing care, starting treatment, navigating disclosure decisions, negotiating stigma, and maintain...
