By integrating strongly plasmonic Au nanoparticles with strongly catalytic TiO2, we observe enhanced photocatalytic decomposition of methyl orange under visible ill...

Aim of Study: Bio lm of Candida albicans signify as a complex cellular congregation with major implication in pathogenicity. This kind of lifestyle of fungus as a biofilm can inhibit immune system function and antifungal therapy, thus complicates the treatment of infectious diseases, particularly in field of chronic infections associated with medical devices. In this study effects of Titanium d...

in this research, tio2 nanoparticles were synthesized by a simple wet chemical method. ticl4 was used as precursor in hydrogen peroxideand ethanol. the tio2 nanoparticles were characterized by transmission electron microscopy (tem), scanning electron microscopy (sem), x-ray diffraction (xrd), electron dispersive spectroscopy (eds) and uv-vis spectrophotometer. the particle size of the as-synthe...

Effect of compressed CO2 on properties of the sodium bis(2-ethylhexyl) sulfosuccinate (AOT)/isooctane/water reverse micellar solution has been studied by phase behavior measurement. UV-vis study indicates that TiO2 in the reverse micelles can be precipitated by compressed CO2 at suitable pressures, while the surfactant AOT remains in the solution. Using this concept, TiO2 nanoparticles synthesi...

Bulk metallic Au is chemically inert and catalytically inactive as a consequence of combination of valence d orbitals and diffused valence s and p orbitals. Recently, Au nanoparticles have been found to be catalytically active when supported on metal oxides such as TiO2, SiO2, Fe2O3, Co3O4, NiO, Al2O3, MgO, etc. 1 6 For example, Au nanoparticles supported on a TiO2(110) surface demonstrate cata...

The aim of this research was to prepare rare metal (Er, Yb)-modified TiO2 nanoparticles by a sol-gel method. The obtained nanoparticles were characterized by BET measurements, UV-Vis spectra and the Laser-induced fluorescence (LIF) method. Visible light photocatalytic activity of the sample was studied by photodegradation of phenol while considering the influence of the dopant concentration. Th...

Densely stacked Ag nanoparticles with an average diameter of 199 nm were effectively deposited on TiO2-coated cicada wings (Ag/TiO2-coated wings) from a water-ethanol solution of AgNO3 using ultraviolet light irradiation at room temperature. It was seen that the surfaces of bare cicada wings contained nanopillar array structures. In the optical absorption spectra of the Ag/TiO2-coated wings, th...

Carbon coated TiO2 (TiO2@C) is fabricated by a convenient and green one-pot solvothermal method, in which ethylene glycol serve as both the reaction medium and carbon source without the addition of any other carbon additives. During the solvothermal process, ethylene glycol polymerize and coordinate with Ti4+ to form the polymeric ligand precursor, then the polymer brushes carbonize and convert...

Immobilization of cellulase from Aspergillus niger on TiO2 nanoparticles was studied by two different approaches--physical adsorption and covalent coupling. A. niger was selected, as it is generally non-pathogenic, is found in nature in the broad range of habitats and produces cellulase extracellulary. For covalent method, TiO2 nanoparticles were modified with aminopropyltriethoxysilane (APTS)....

The focus of this work is on composite materials of inorganic nanoparticles such as TiO2 embedded within microspheres of a responsive polymeric network. Microgels of N-isopropylacrylamide (NIPAM) with interpenetrating (IP) linear chains of poly(acrylic acid) (PAAc) were synthesized to promote the incorporation of TiO2. Dynamic light scattering measurements of the IP-microgels in aqueous environ...
