The photo-catalytic degradation of an azo dye - Amaranth (AM) - has been investigated in TiO(2)/UV aqueous suspensions. The results obtained from the experiments during H(2)O(2)/TiO(2) addition show that the highest decolorization rate is provided by the combination of (UV+TiO(2)+H(2)O(2)). The decolorization efficiencies were 17%, 26%, 38% and 64% in the runs UV, UV+H(2)O(2), UV+TiO(2) and (UV...

a bacterial strain (strain ps) was isolated from the textile effluents carrying serilene black bnfs® (c.i. disp. blk. mix) disperse dye. the isolate was able to decolorize the dye without the need for any exogenous carbon source. full sequencing of its 16s rrna indicated that bacillus sp strain ps is related to bacillus cereus groups.  silica- gel-thin layer chromatography of serilene black dye...

conclusions there was no significant statistical difference between mta and cem cement in sealing ability (p > 0.05). results the mean apical penetration of dye in the mta group was 0.94 mm while in the cem cement group this was 1.17 mm. eighty percent of the mta group and 75% of the cem cement group didn’t have any dye leakage. the p level was greater than 0.05 (0.592). materials and methods e...

Cryotherapy has similar cure rates to topical salicylate (a pharmacologic therapy) for nongenital common warts (strength of recommendation [SOR]: B, based on systemic review of variable quality randomized trials). Duct tape may be equivalent to cryotherapy (SOR: B, based on a single randomized trial). CO2 laser, photodynamic therapy, pulsed dye laser (PDL), and Er:Yag laser therapies may also b...

BACKGROUND Infantile hemangiomas (IH) are common pediatric tumors. This meta-analysis was performed to review the therapeutic efficacy and safety of pulsed dye laser (PDL) in the treatment of IH. METHODS Seven databases were searched, including PubMed, OvidSP, Karger, Elsevier, EMBASE, Web of Science and Wiley Online Library. The review collected the characteristics of year of publication, he...

Current work employs dye extracted from leaves of Costus woodsonii as a new sensitizer for dye-sensitized solar cells (DSSCs). The leave was in three different solvents namely ethanol, methanol, and acetone. Extraction carried out by the freezing method. DSSCs with configuration TiO2/dye/electrolyte/Pt were assembled. dyes DSSC methanol extract has an efficiency 0.23 % short-circuit current den...

background textile dyes are the largest organic compounds associated with some problems for the environment. advanced oxidation process is the most effective method for dye removal from wastewater. objectives the aim of this study was to investigate the efficiency of the photo fenton process for decolorization of direct red 81 (dr 81) dye, and to determine the optimal process conditions. method...

In this study, we examine macrocyclic compounds to determine whether they can provide a safer replacement and stable complex for BPA in thermochromic dyes. To achieve objective, series of compounds, Methyl-N-benzylhexahomotriazacalix[3]arene (MeAC3), p-Chloro-N-benzylhexahomo-triazacalix[3]arene (ClAC3), ?-Cyclodexdrin (?-CD), ?-Cyclodexdrin (?-CD), p-tert-Butylthiacalix[4]arene (TC4), Calix[4]...
