Abstract Nanostructured bio-photocatalyst hydroxyapatite (HAp) was synthesized by a simple and productive wet chemical precipitation method to explore the photocatalytic performance of material for degradation Remazol Brilliant Blue R (RBBR) dye. Wet chemically nano-HAp characterized through x-ray diffraction, Transmission electron microscope, scanning N 2 -adsorption–desorption, thermo gravimetric analyzer, Fourier transform infrared UV–vis absorption techniques. Photocatalytic RBBR under...
In the present article, we have prepared thick films of titanium dioxide nanoparticle (T - NP), nanowire NW) and nanotube NT) by screen printing for study sensing parameter such as operating temperature, response/ recovery time gas uptake capacity alcohol vapour methanol, ethanol propanol at low concentration level (10 ppm). Sensing materials are characterized means XRD to identify phase grain size, surface morphology is visualized SEM, presence functional group observed FTIR thermal...
In this paper, we report an extremely low cost and highly efficient method for fabrication of visible light photo-detector using nano-crystalline lead sulfide (PbS) thin film. The film was fabricated on 300 GSM paper via spray pyrolysis technique at 100 °C. Structural morphological analysis the confirms nature PbS with size ∼ 50 nm uniform coating paper. Photo-detector devices are prepared by drawing contacts 4B pencil keeping a gap 1 mm between electrodes. Photo-detection property under...

Present scenario requires methods for treatment of industrially waste water polluted with hazardous chemicals and dyes. This work reports efficient utilization nano-ceramic 'hydroxyapatite' degradation Indigo Carmine dye present in under ultra violet light illumination. The photo-catalytic experiment is carried out via artificially polluting at three different concentration (5, 10, 20 mg/L) presence hydroxyapatite nano-powder (25 mg). After 180 min illumination, almost 63, 61 43 % observed...
Modulation in resistance switching characteristics of TiO2 thin film fabricated on aluminum substrate is investigated under optical illumination. The average thickness about 200 nm. current–voltage the Pt/TiO2/Al structure show a good rectifying property with unipolar resistive behavior. This behavior observed to be modulated by Photo-carriers generated during illumination shifts set and reset voltage lower values. study helpful for exploring effect metal oxides as multifunctional materials...
