Virtual Reality for Neurorehabilitation and Cognitive Enhancement.

Our access to computer-generated worlds changes the way we feel, how we think, and how we solve problems. In this review, we explore the utility of different types of virtual reality, immersive or non-immersive, for providing controllable, safe environments that enable individual training, neurorehabilitation, or even replacement of lost functions. The neurobiological effects of virtual reality on neuronal plasticity have been shown to result in increased cortical gray matter volumes, higher concentration of electroencephalographic beta-waves, and enhanced cognitive performance.

Photocatalytic degradation of industrial acrylonitrile wastewater by F-S-Bi-TiO catalyst of ultrafine nanoparticles dispersed with SiO under natural sunlight.

Highly active photocatalyst, having certain anti-ionic interfering function, of F, S and Bi doped TiO/SiO was used for the first time to degrade the organic pollutants in acrylonitrile industrial wastewater under natural sunlight. The photocatalyst were prepared and characterized by UV-Vis, XRD, TEM, EDS, Nitrogen physical adsorption and XPS technique. UV-Vis analysis revealed addition of F, S and Bi into the lattice of TiO led to the expansion of TiO response in the visible region and hence the efficient separation of charge carrier.
