Titanium+gold = new gold standard for artificial joints
Titanium gold new gold standard artificial joints
2016/8/1
Titanium is the leading material for artificial knee and hip joints because it’s strong, wear-resistant and nontoxic, but an unexpected discovery by Rice University physicists shows that the gold stan...
Titanium is a language and system for high-performance parallel scientific computing. Titanium uses Java as its base, thereby leveraging the advantages of that language and allowing us to focus attent...
Sulfuric acid recovery from titanium white (pigment) waste liquor using diffusion dialysis with a new series of anion exchange membranes—static runs
Ion exchange membrane Diffusion dialysis Titanium white waste liquor Poly(2,6-dimethyl-1,4-phenylene oxide)
2016/3/25
In this paper, a new series of anion exchange membranes have been produced from linear engineering plastics poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) by conducting the processes of bromination, chl...
Application of titanium-in-quartz thermobarometry to greenschist facies veins and recrystallized quartzites in the Hsüehshan range, Taiwan
Accuracy reliability green schist facies rocks titanium concentration crystallization quartzite vein quartz snow-capped mountains
2015/1/5
The accuracy, reliability and best practises of Ti-in-quartz thermobarometry (TitaniQ) in greenschist facies rocks have not been established. To address these issues, we measured Ti concentrations in ...
Evidence for Correlated Titanium and Deuterium Depletion in the Galactic ISM
