The unique properties and numerous applications of nanocrystalline titanium dioxide (TiO2) are stimulating research on improving the existing developing new synthesis methods. In this work, we demonstrate for first time possibilities extraction–pyrolytic method (EPM) production TiO2 powders. A titanium-containing precursor (extract) was prepared by liquid–liquid extraction using valeric acid C4...

This work involves a basic research program that will ultimately enable new solar technology for a highly efficient and low cost water splitting system. The system consists of a unique tandem cell where the sunlight is first incident upon a photocathode, and light transmitted through the photocathode is absorbed in the photoanode. The photocathode generates two electrons per absorbed photon thr...

Nanocrystalline anatase TiO2 is a robust model anode for Li insertion in batteries. The influence of nanocrystal size on the equilibrium potential and kinetics investigated with operando spectroelectrochemistry thin film electrodes. Distinct visible infrared responses correlate electron accumulation, respectively, these optical signals are used to deconvolute bulk from other electrochemical res...

All electronic devices are plagued with 1/f noise originating from many causes. The most important factors contributing to 1/f noise in a semiconductor is believed to be recombination of carriers and their trapping at defects and impurity sites. Adsorption of moisture and electron acceptor molecules enhances the intensity of 1/f noise. Amazingly, some molecular species that strongly chelate to ...

The dye-sensitized solar cells (DSSC) have been regarded as one of the most promising new generation solar cells. Tremendous research efforts have been invested to improve the efficiency of solar energy conversion which is generally determined by the light harvesting efficiency, electron injection efficiency and undesirable electron lifetime. In this review, various characteristics of dye-...

Chemical modification of cotton-rich fabrics with TiO2 nanoparticles results in photoactive self-cleaning textiles, which can provide, under UV or solar radiation, complete oxidation low-molecular compounds, degradation supramolecular structures, and inactivation microorganisms due to the photocatalytic effect. In this paper, we describe, based on example influenza A (H1N1) virus, a photoinduce...
