Purpose: The purpose of this study is to compare the time-course changes in condylar long axis and skeletal stability after sagittal split ramus osteotomy (SSRO) with unsintered hydroxyapatite (u-HA) / poly-L-lactic acid (PLLA) plate, PLLA plate versus titanium plate. Patients and Methods: Of 60 Japanese patients diagnosed of mandibular prognathism, 20 underwent SSRO with u-HA/PLLA plate system...

Lumbar interbody fusion is commonly performed by inserting an implant into the disc space. Interbody fusions are benefi cial because they result in high fusion rates, maintain spinal alignment, and allow for indirect decompression of the neuroforamen.1 Currently, the two most commonly used implants are made of polyether ether ketone (PEEK) or allograft bone. Threaded titanium (Ti) cages were us...

As one of the valve metals (including Ti, Al, Ta, Nb, V, Hf, W), titanium is protected by a thin titanium oxide layer which spontaneously forms on its surface when exposed to air or other oxygen containing environments. This oxide passive layer is typically 2 to 5 nm thick and is responsible for the well-documented corrosion resistance property of titanium and its alloys. Because of this and th...

We introduce the first example of isoreticular titanium–organic frameworks, MUV-10 and MUV-12, to show how different affinity hard Ti(IV) soft Ca(II) metal sites can be used direct selective grafting amines. This enables combination Lewis acid titanium centers available -NH2 in two sizeable pores for cooperative cycloaddition CO2 epoxides at room temperature atmospheric pressure. The molecules ...

The production of titanium dioxide via the sulfuric acid process generates large amounts acidic wastewater. Investigating possibility reusing this wastewater after deep treatment can reduce pollutant discharge and conserve water resources. In a pilot study, dual-membrane method ultrafiltration (UF) reverse osmosis (RO) was employed to perform treatments sulfuric-acid–titanium-dioxide findings s...

Anionic polyurethane dispersants APUDs were used as dispersing agents in formulation of waterborne paints. The APUDs were synthesized by three steps. In the first step, macromonomer diisocyanate having carboxylic acid was prepared by isophorone diisocyanate IPDI, dimethylol propionic acid DMPA in presence of acetone as solvent and dibutyltin dilaurate DBTDL as catalyst. Then, carboxylic polyure...

Highly uniform submonolayer to multilayer thin films of titanium dioxide supported on high surface area silica gel have been synthesized by atomic layer deposition (ALD) using titanium tetrachloride (TiCl4) and titanium isopropoxide (TTIP) as metal precursors. The deposition rate of titania films from TiCl4 was found to be stable in the 150-300 °C temperature range, which is slightly higher tha...
