The application of Leuco Crystal Violet (LCV) for the enhancement of footwear and fingerprint impression evidence was first utilized in the FBI Laboratory in late 1993, after learning from Mr. John F. Fischer (1) of the formulation of this reagent. Mr. Fischer subsequently made a presentation on this topic at the International Symposium on Footwear and Tire Tread Impression Evidence at the FBI ...

Two commercial products containing titanium dioxide, P-25 and Kronos 7000, were used for the detailed investigation of advanced degradation crystal violet (CV) dye by photocatalysis. The parametric study concerning influence initial concentration, photocatalyst dose, pH medium hydrogen peroxide addition in reaction batch was performed. net superiority decolorization further highlighted measurin...

Effluent of various industries contain number of inhibitory substances which are continuously added in sea via river and results in water pollution. There is need to degrade the organic content to abate water pollution. In the present study, actinomycetes were isolated on glycerol aspargine agar from marine sample of Calangut beach, Goa. The isolates were tested for their potential to tolerate ...

Carboxymethyl cellulose (CMC)/titanium dioxide (TiO2) was prepared using gamma irradiation at different doses. used as a matrix and TiO2 in contents added (0.25, 0.5, 1, 1.5 wt%) filler. The polymer composite films were irradiated doses of 5, 10 15 kGy 60Co γ-ray to form crosslinked network structure. described by diagnostic procedures including X-ray diffractometer, scanning electron microscop...

The effect of oxidative stress exerted by 0.03% crystal violet, 0.3% bile salt, 4.0% NaCl and 8% ethanol on the survival and production of virulence factors among Acinetobacter haemolyticus isolates obtained from wastewater and river water samples was investigated. Though generally there was insignificant lethal effect against all the isolates, crystal violet exerted the highest lethal effect f...
