Chlorhexidine adsorption to anatase and rutile Titanium Dioxide
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2007Co-Authors: Michele E. Barbour, Dominic Sullivan, D C JaggerAbstract:Many dental and biomedical implants are composed primarily of Titanium. Titanium metal is coated with a layer of Titanium Dioxide under ambient conditions. Crystalline Titanium Dioxide most commonly occurs in one of two crystal structures: anatase and rutile. Recently, there has been interest in functionalisation of implant surfaces with antimicrobials, to reduce the likelihood of bacterial infestation and colonisation of the surrounding tissues. In this study, the adsorption and subsequent desorption of a common antimicrobial, chlorhexidine digluconate, to anatase and rutile Titanium Dioxide was investigated in two different buffers (MES, PBS). Chlorhexidine in MES buffer adsorbed rapidly (

Effect of Concentration TTIP on Size Nano-Powder Titanium Dioxide (TiO2)
Advanced Materials Research, 2013Co-Authors: A.z. Zainurul, M.f. Achoi, Mohamad Rusop, Saifollah AbdullahAbstract:In this work, Titanium Dioxide (TiO2) powder was prepared by sol gel method using Titanium (IV) Isopropoxide (TTIP) as precursor and Ethanol (C2H5OH) as solvent. The sol-gel was heated at temperature 150°C in 1 hour. Titanium Dioxide (TiO2) powder was milled with constant ball to powder ratio (BPR) of 10:1 with speed 600 rpm. Then the sample was characterized using Particle Size Analyzer, Raman Spectroscopy and Scanning Electron Microscope (SEM). Titanium Dioxide (TiO2) powder was prepared with three different concentration of TTIP to the size of Titanium Dioxide (TTIP) powder. Titanium Dioxide (TTIP) powder was milled with ball milling to produce nanopowder of Titanium Dioxide (TiO2).

Preparation of Antibacterial WPU Nanometer Titanium Dioxide Composite
2016Co-Authors: Shi Zhou, Chun-ying Huang, Bing Zhou, Jia Jun ChenAbstract:Abstract: In the paper, WPU nanometer Titanium Dioxide composite is made mainly of polypropylene glycol (PPG), 2, 4-toluene diisocynate (TDI), nanometer Titanium Dioxide (TiO2), oleic acid (OA), dimethylolpropionic acid (DMPA), dibutyltin dilaurate (DBTDL), triethylamine (TEA), polypropylene glycol phosphate (PPG-P). Feature of nano particle is analyzed and tested by scanning electron microscope; Fourier infrared spectrum of nanoparticle and composite is tested by fourier infrared spectrometer under room temperature; thermal property test is conducted to composite by thermogravimetric analyzer; XRD test is conducted to nanoparticle and compound thin-film material by X-ray diffractometer; mechanical property of composite is tested by universal stretcher, proving that Titanium Dioxide does not change structure of WPU and Titanium Dioxide keeps the original crystal structure instead of being destroyed. Thermogravimetric analysis shows that Titanium Dioxide raises thermal stability of composite better; mechanical properties prove that increase of 2wt % nanometer Titanium Dioxide can raise mechanical properties of WPU. Titanium Dioxide has extensive application prospect in production and life because it has optical activity and can raise antibiotic property of WPU. Polyurethane is the floorboard of the polymer of repetitive carbamic acid esters (-NHCOO-) an

Fouling and Inactivation of Titanium Dioxide-Based Photocatalytic Systems
Critical Reviews in Environmental Science and Technology, 2015Co-Authors: Aaron Katz, Leonard D. Tijing, Andrew M. Mcdonagh, Ho Kyong ShonAbstract:Titanium Dioxide is an effective photocatalyst for the breakdown of many environmental contaminants. The complex mixtures that can occur in water matrices can significantly affect the breakdown of the contaminants in water by Titanium Dioxide (TiO2). The authors discuss a wide variety of foulants and inhibitors of photocatalytic TiO2 systems and review different methods that can be effective for their fouling prevention. Approaches to regenerate a fouled or contaminated TiO2 catalysts are explored and the effect of substrates on immobilized Titanium Dioxide is also reviewed.
