“…Ions such as Cu 2+ and Ag + in combination with TiO 2 were reported to enhance its antimicrobial activity (72). Furthermore, the photocatalytic activity of TiO 2 was reported as performed against pure bacterial cultures, mixed cultures (128) and natural communities (129)(130)(131). As a general concept, photocatalytic surfaces or suspensions are referred to as being self-disinfecting rather than self-sterilizing.…”

Int J Artif Organs ( 2011; : 9) 929-946 34 TITANIUM OXIDE AND ANTIBACTERIAL SURFACES IN BIOMEDICAL DEVICES Device-related infections: a clinical demand driving material science researchAn increasing number of clinical procedures requires the use of biomedical devices, whose widespread presence in modern therapeutic treatments is driving the demand for better performances and longer reliability. One of the major issues of both short-term devices and implantable prostheses is represented by device-related infections (DRIs) Accepted: August 31, 2011 rEViEW due to bacterial colonization and proliferation (1). About half of the 2 million cases of nosocomial infections that occur each year in the United States are associated with indwelling devices (2): these infections generally require a longer period of antibiotic therapy and repeated surgical procedures, resulting in potential risks for the patient and increased costs for the healthcare system. The planktonic bacteria that colonize a device surface tend to form a biofilm and the sessile bacterial cells, enclosed in a self-produced polymeric matrix of this kind, can withstand host immune responses and generally show extraordinary antibiotic resistance (3). Eventually, bacteria rapid multiply and disperse in planktonic form, giving rise

“…Ozone has been applied to the treatment of waters primarily due to its strong disinfection and sterilisation properties (Araña et al, 2002). Its application for the treatment of waters containing pharmaceutical residues is now a broad area of research (Balcioglu and Okter, 2003;Ternes et al, 2003;Andreozzi et al, 2005;Huber et al, 2005;Andreozzi et al, 2006;Nakada et al, 2007;Dantes et al, 2008).…”

“…Compared with the other conventional wastewater treatment means, this technology has such advantages as: (1) wide application, especially to the molecule structure-complexed contaminants which cannot be easily degraded by the traditional methods; (2) the nanoparticles itself have no toxicity to the health of our human livings and (3) it demonstrates a strong destructive power to the pollutants and can mineralize the pollutants into CO 2 and H 2 O. Due to the excellent features of this technology, it appears promising and has drawn the attention of researchers of at home and abroad [10][11][12].…”

La 0.5 Pb 0.5 MnO 3 perovskite-type oxide is prepared by sol-gel method. The physical and chemical properties of a nanoparticle were characterized by differential thermal analysis (DTA), thermogravimetric analysis, XRD, and scanning electron microscopy (SEM) techniques. The adsorption effect of the sample is evaluated by removal of Eosin dye from aqueous solution. The results of XRD indicate that the perovskite-type oxide has a good crystal phase at 650°C. The DTA, XRD, and SEM data revealed that La 0.5 Pb 0.5 MnO 3 nano particles are prepared successfully via sol-gel modified pechini method. These nanoparticles showed the excellent adsorption efficiency towards Eosin dye in aqueous solution. The adsorption studies were carried out at different pH values, dye concentrations, various adsorbent dosages, and contact time in a batch experiment. The dye removal efficiency was found to be decreased with increasing in initial pH of the dye solution, and nanoadsorbent exhibited good dye removal efficiency at acidic pH specially pH 1. Experimental results indicated that the adsorption kinetic data follow a pseudofirst-order rate for tested dye. The isotherm evaluations revealed that the Freundlich model attained better fits to the experimental equilibrium data than the Langmuir and Temkin models.
