BACKGROUND Poor mechanical properties are among the main limitations of acrylic resins. Addition of titanium dioxide (TiO2) nanoparticles to acrylic resin has been shown to improve its mechanical properties with an adverse effect on its color. Thus, this study sought to assess the tensile and impact strength of a color modified heat cure acrylic resin reinforced with TiO2 nanoparticles. MATER...

The effect of mesoporous titanium dioxide nanoparticles on germination traits black saxaul seeds (Haloxylon aphyllum (Minkw.) Iljin) under drought stress

The possibility to recover the titanium dioxide (TiO2) nanoparticles synthesized in sodium bis(2-ethylhexyl) sulfosuccinate (AOT) reverse micelles by compressed CO2 was investigated. UV-Vis study showed that TiO2 nanoparticles could be deposited from the reverse micelles by the dissolved CO2. The nanoparticels were prepared and characterized by the transmission electron microscopy (TEM). The re...

Electronic scanning microscopy was used in the work to obtain the image and to identify the sizes of titanium dioxide (TiO2) nanoparticles 21 ± 5 nm. The qualitative and quantitative elemental analysis of the preparations of the caecum, antrum, myometrium, kidneys, and lungs of the rats, burdened with titanium dioxide, was also performed. It was established using the tenzometric method in the i...

titanium dioxide (tio2)nanoparticles have been frequently employed in the environmental treatment and purification purposes as a cheap and highly efficient photocatalyst. a photocatalyst can facilitate the breakdown and removal of a variety of environmental pollutants at room temperature. tio2 photocatalyst is the best candidatebecause of its strong oxidized ability, non-toxicity and longtherma...

This photocatalytic conversion of carbon dioxide laboratory experiment is designed for an advanced undergraduate chemistry or chemical engineering majors laboratory course. It introduces the science of emerging sustainable energy technologies through hands-on experimentation. By photo-irradiating a glass flask containing water, catalyst, and carbon dioxide, students explore the potential of new...
