The influence of distal-end heat treatment on deflection of nickel-titanium archwire
OBJECTIVE The aim of this in vitro study was to evaluate the deflection-force behavior of nickel-titanium (NiTi) orthodontic wires adjacent to the portion submitted to heat treatment. MATERIAL AND METHODS A total of 106 segments of NiTi wires (0.019 x 0.025-in) and heat-activated NiTi wires (0.016 x 0.022-in) from four commercial brands were tested. The segments were obtained from 80 archwire...
متن کاملTitanium Dioxide Nanofibers and Microparticles Containing Nickel Nanoparticles
The present study reports on the introduction of various nanocatalysts containing nickel (Ni) nanoparticles (NPs) embedded within TiO2 nanofibers and TiO2 microparticles. Typically, a sol-gel consisting of titanium isopropoxide and Ni NPs was prepared to produce TiO2 nanofibers by the electrospinning process. Similarly, TiO2 microparticles containing Ni were prepared using a sol-gel syntheses p...
متن کاملOn the Charge State of Titanium in Titanium Dioxide.
The oxidation state of titanium in titanium dioxide is commonly assumed to be +4. This assignment is based on the ionic approximation and is used ubiquitously to rationalize phenomena observed with TiO2. It implies a charge state +4 and that no further oxidation of the metal center is possible. We present a comprehensive electronic structure investigation of Ti ions, TiO2 molecules, and TiO2 bu...
متن کاملGraphite / Titanium Dioxide Composite
Nanosized titanium dioxide (TiO2) in its anatase form is the most frequently studied and as well as used photocatalyst. There are several syntheses procedures which enable to achieve photocatalytic TiO2. The solgel method utilizing titanium alkoxides is used most often. Alternative precursors such as titanium tetrachloride and titanyl sulphate are also frequently employed. Nowadays the environm...
متن کاملMultiwalled carbon nanotube coating on titanium.
Carbon nanotubes (CNTs) have excellent chemical durability, mechanical strength and electrical properties. Therefore, there is interest in CNTs for not only electrical and mechanical applications, but also biological and medical applications. We coated titanium, a common material for dental implants, with multiwalled carbon nanotubes (MWCNTs). First, titanium was aminated and covered with colla...
