The capability to prepare samples accurately and reproducibly for analysis of tritium (3H) content by accelerator mass spectrometry (AMS) greatly facilitates isotopic tracer studies in which attomole levels of 3H can be measured in milligram-sized samples. A method has been developed to convert the hydrogen of organic samples to a solid, titanium hydride, which can be analyzed by AMS. Using a t...

Titanium behaves inert in the terms of its interaction with living tissue. Titanium implants are not usually rejected by the organism, nevertheless creation of the strong implant-bone bond can be long term and difficult process. Research aimed at applications of metallic biomaterials should be therefore focused on bioactivation of the implant surface, which could lead to faster and easier accep...

purpose: to compare the complications of pegging between the polycarbonate peg system and the titanium peg system. method: complications associated with pegging (polycarbonate: bio-eye or titanium: dr-perry new p-k) were reviewed from the hospital records of 153 patients over 5 years. results: out of 153 cases, 96 (62.3%) were male and 57 (37.7%) were female. mean age was 27.7 yr (6-59 yr). in ...

Titanium is an ideal material for use in prosthodontics because of its biocompatibility, corrosion resistance, and mechanical strength combined with its lightweight. Recently the use of titanium and titanium alloys for fixed restorations has increased substantially, mainly due to the improvement of techniques for the casting titanium and its alloys. This article reviewed the studies on titanium...

Combustion synthesis is a special thermophysico-chemical process applied for production of intermetallic compounds. In the present work, a reaction–diffusion numerical model was developed to analyze the combustion synthesis of aluminide intermetallics by self-propagating high-temperature synthesis process. In order to verify the reliability of the numerical model, an experimental setup was desi...
