Theoretical Investigations of Dye-Sensitized Solar Cells
This presentation considers theoretical investigations of dye-sensitized solar cells (DSSC). Theoretical methods were applied to investigate the interactions between titanium dioxide nanoparticles and sensitizers. The ONIOM model was used to obtain the geometries of different conformers of dye molecules with TiO2 and their binding energies. TD-DFT calculations were carried out to obtain the absorption spectra and the relative orbital energy levels of sensitizers and TiO2.

A major obstacle to fulfilling the therapeutic promise of gene therapies for hereditary brain diseases, such as Huntington’ Disease (HD), is the requirement for viral vectors and/or an invasive delivery system (stereotaxic injection into brain or infusion into the intrathecal space). HD is an autosomal dominant neurodegenerative disease for which several clinical trials have demonstrated gene-lowering effects following intrathecal administration.

This commentary shows the development of a new optical biosensor, based on cell immobilization of Pseudomonas Fluorescens HK44, in nano and micro-tubular cellulose (TC) and a mixture of carbohydrate nanotubes (CHNTs) and carbohydrate micro-tubes (CHMTs). Methodology follows, this biocatalyst can be industrialized with the use of a single tank immobilized cell bioreactor (ICB).

Fabrication of dye thin films is accomplished through physical vapor deposition with a thickness of 150 ± 5 nm. Kinetically, the reduction of permanganate ion as a multi-equivalent oxidant by acriflavine hydrochloride (ACFH) in a neutral medium has been studied spectrophotometrically. In the presence of a pseudo-first-order reaction, the experimental results suggest fractional first-order kinetics in [ACFH] and a first-order dependency in [MnO4-].

In this study, Mn2+ substituted Co0.8−x Mnx Zn0.2 (where x = 0.0, 0.1, 0.2, and 0.3) ferrites are prepared by a coprecipitation method to study the effect of Mn2+ions on the structural and morphological properties. These ferrites are characterized by X-ray powder diffraction (XRD), and Fourier transform infrared. X-ray diffraction patterns of the prepared samples confirm partial substitution of Mn2+ ions that does not change the basic structure of Co0.8 Zn0.2 Fe2O4.
