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...

in this study, catalyst of rutile titanium dioxide nanoparticles (rtio2-np) has been investigated for the removal and reduction of unburned hydrocarbons as benzopyran. to evaluate and calculate the thermodynamic properties of this aim, pollutants are closed to the nanoparticles and converted them into other products and the carbon dioxide molecules are simulated in the 12th steps. the geometric...

Nanoscale titanium dioxide (nano-TiO2) has been widely used in industry and medicine. However, the safety of nano-TiO2 exposure remains unclear. In this study, we evaluated the liver, brain, and embryo toxicity and the underlying mechanism of nano-TiO2 using mice models. The results showed that titanium was distributed to and accumulated in the heart, brain, spleen, lung, and kidney of mice aft...

The extensive use of titanium dioxide nanoparticles (nano-TiO2) in many consumer products has raised concerns about possible risks to the environment The magnitude of the threat may depend on whether nano-TiO2 remains dispersed in the environment, or forms much larger-sized aggregates or clusters. Currently, limited information is available on the issue. In this context, the purpose of the pres...

We present a multiscale computational approach for the first-principles study of bio-nano interactions. Using titanium dioxide as case study, we evaluate affinity titania nanoparticles to water and biomolecules through atomistic coarse-grained techniques.
