Organic pollutant is an environmentally harmful and ubiquitous aquatic with extensive production application. In this study, a unique novel TiO2-based dual-sensitized heterojunction photocatalyst (PbS/CdS/TiO2) was successfully obtained by one step hydrothermal method, chemical bath deposition (CBD) method ionic layer adsorption reaction (SILAR) method. Scanning electron microscopy, X-ray photo...

T-PM-Pol USE OF THE DYE HOECHST 33258 IN A MODIFICATION OF THE BROMODEOXYURIDINE PHOTOLYSIS TECHNIQUE FOR THE ANALYSIS OF DNA REPAIR. B. S. Rosenstein* and R. B. Setlow (Intr. by M. Simon), Biology Dept., Brookhaven Nation¶l Laboratory, Upton, N.Y. 11973. A modification of the BrdU photolysis technique used in the measurement of the repair of damage in DNA has been developed employing the bisbe...

Though an important and chronic source of dyes released to the environment, determination release that occurs during household or industrial washing is usually disregarded. The main scope this study reveal extent dye through washing, understand if modification cotton fabrics with cationic polymers could reduce it. Modified fabrics, dyed Acid Blue 281 (AB) by a mixture reactive Novacron Yellow S...

The synthesis and photovoltaic study of five dyes based on 4H-pyranylidene moiety as donor is reported. A thiophene unit conjugated with/without an ethynyl bond acts the π-relay benzoic acid anchor group a trifluoromethyl group. Their electrochemical optical properties are analyzed by using joint experimental theoretical approach. presence leads to enhancement molar extinction coefficient, bein...

Dye-sensitized solar cells (DSSCs) utilize high surface area metal oxide sintered particle networks to absorb molecular dyes and transport injected charge carriers. While this sintered particle architecture allows liquid electrolyte DSSCs to achieve efficiencies up to 11%, slow charge transport through the semiconductor network limits the amount of modification that can be made to the electroly...

Acrylonitrile-Styrene co-polymer was prepared by solution polymerization and fabricated into nanofibers using the electrospinning technique. The nanofiber polarization was enhanced through its surface functionalization with carboxylic acid groups by simple chemical modification. The carboxylic groups’ presence was dedicated using the FT-IR technique. SEM showed that the nanofiber attains a unif...
