Examples of titanium in the following topics:

  • Titanium, Chromium, and Manganese

    • Titanium is a strong, lustrous transition metal.
    • Titanium was discovered in Cornwall, Great Britain, in 1791, by William Gregor.
    • In its unalloyed condition, titanium is as strong as some steels, but 45% lighter.
    • Titanium is one of the least dense, strong, and corrosion-resistant elements.
    • Titanium is commonly used in airplanes, golf clubs, and other objects that must be strong but lightweight.
  • Clinical Advances in Bone Repair

    • Osseointegration is changing this by integrating a titanium armature with the remaining bone.
    • The titanium and bone become an integrated unit that improves feeling and mobility when the prosthetic device is attached to the armature.
    • For osseointegrated dental implants, metallic, ceramic, and polymeric materials have been used, in particular titanium.
    • Clinical studies on mammals have shown that porous metals, such as titanium foam, may allow the formation of vascular systems within the porous area.
    • This image shows a microscopic hisotlogical section of bone integrated to the titanium surface of a dental implant (black).
  • Ziegler-Natta Catalytic Polymerization

    • The catalyst formed by reaction of triethylaluminum with titanium tetrachloride has been widely studied, but other metals (e.g.
    • Polymerization of propylene through action of the titanium catalyst gives an isotactic product; whereas, a vanadium based catalyst gives a syndiotactic product.
  • Molar Mass of Compounds

    • For example, the atomic mass of titanium is 47.88 amu or 47.88 g/mol.
    • In 47.88 grams of titanium, there is one mole, or 6.022 x 1023 titanium atoms.
  • Epoxidation

    • Sharpless, Scripps Research Institute, has transformed this general epoxidation reaction into a powerful enantioselective procedure, by the addition of a chiral tartrate ester ligand to a titanium alkoxide catalyst.
    • When mixed with one equivalent of diethyl tartrate, titanium tetraisopropoxide forms a dimeric complex with the loss of two isopropyl alcohol molecules.
    • A proposed structure for this complex is shown in the first diagram below, with the titanium atoms colored green.
  • Occurrence of Metals

    • Metals that can be found as native deposits singly and/or in alloys include antimony, arsenic, bismuth, cadmium, chromium, cobalt, indium, iron, nickel, selenium, tantalum, tellurium, tin, titanium, and zinc.
    • Other significant metallic alloys are those of aluminium, titanium, copper, and magnesium.
    • The alloys of aluminium, titanium, and magnesium are valued for their high strength-to-weight ratios, and magnesium can also provide electromagnetic shielding.
  • Compromised Host

    • Surgical drain on the left hand after surgery of Bennet's fracture basis MTC primi manus 1. sin (S62.20) which was treated by alignment of a fracture and inside fixation by two titanium screws MS.
  • Sun Damage, Sunscreen, and Sunblock

    • Sunscreens contain one or more of the following ingredients: organic chemical compounds that absorb ultraviolet light; inorganic particulates that reflect, scatter, and absorb UV light (such as titanium dioxide, zinc oxide, or a combination of both); organic particulates that mostly absorb light-like organic chemical compounds but contain multiple chromophores, may reflect and scatter a fraction of light like inorganic particulates, and behave differently in formulations than organic chemical compounds.
  • 1:3-Diastereoselection in Reactions with Chiral Aldehydes

    • As expected, the E-borinates give α:β-anti diastereomers exclusively, and the Z-titanium enolates strongly favor the α:β-syn family of isomers.
    • Other combinations show diminished β:γ-syn selectivity, and in the case of the Z-titanium enolates anti-Felkin-Ahn selectivity narrowly predominates.
