(1) Background: The development of a biocompatible material for direct additive manufacturing maxillofacial extraoral prosthesis is still challenging task. aim the present study was to obtain photocurable PDMS, with nano TiO2 inclusions, directly 3D printing extraoral, prosthesis. biocompatibility newly obtained nanocomposite also investigated; (2) Methods: 2.5% (m/m) titania nanoparticles (TiO...

Recently, TiO2 has been widely used as a photocatalyst for degradation of environmental pollutants. In the present study, the advantage of metal doping onto TiO2 for enhanced photocatalitic activity has been investigated. Copper-Titanium dioxide nanocomposites were prepared by the sol-gel method in the presence of Carboxy Methyl Cellulose (CMC), Pectin, and Poly Ethylene Glycol (PEG) as additiv...

Infections caused by microorganisms are a global public health problem that continually demands new antimicrobial strategies. The generation of reactive oxygen species (ROS) photocatalytic materials is an attractive approach to combat microbes. Along these lines, titanium dioxide (TiO2) constitutes outstanding light-driven ROS generator. However, the wide bandgap this semiconductor limits its u...

TiO2—methylcellulose (MC) nanocomposite films processed by the sol-gel technique were studied for phocatalytic applications. Precalcined TiO2 nanopowder was mixed with a sol and heat treated. The sol suspension was prepared by first adding titanium tetra isopropoxide (Ti(OPr)4 or TTP) to a mixture of ethanol and HCl (molar ratio TTP:HCl:EtOH:H2O = 1:1.1:10:10) and then adding a 2 wt.% solution ...

MoS2-TiO2 nanocomposite catalysts with Janus structure were synthesized via facile one-step solvothermal method. X-ray diffraction, high resolution transmission electron microscope, NO chemisorption and photoelectron spectroscopy applied to characterize the composition nanostructure of catalysts. Experimental results revealed that composed MoS2 layers (few stacked 1–3 short slabs 2–10 nm) TiO2 ...

The importance of nanosized material in many contemporary applications is already known. However special properties such as superparamagnetism, semi-conducting and photocatalysis are unique to single metallic oxide. Recent advances in information technology, catalysis, and medicine often require materials that posses a combination of two or more of these properties. Nanocomposite materials pres...
