Figure S1. Density of states (DOS) for the periodic structures of TiO2 anatase (a), phenyl-acac-TiO2 (b), and 3-acac-pyran-2-one-TiO2 (c), calculated at the extended Hückel level. The filled black lines in (b)-(c) are the projected DOS of the dye chromophores. The blue arrows point to the electronic states with a predominant contribution of HOMO, and the red arrows point to the electronic state...

Incorporation of dichroic dyes substantially improves the contrast of polymer dispersed liquid-crystal (PDLC) shutters. The efficiency of dichroic dyes in a PDLC shutter depends on the scattering efficiency of the film, the dichroic ratio of the dye, the order parameter of the dye in the liquid crystal, and the fraction of dye dissolved in the droplets. Ultraviolet/visible spectroscopy can be e...

Carbon prepared from Gloriosa superba pericarp was used to remove reactive orange 107 and reactive black 5 from aqueous solution by adsorption technique under varying conditions of agitation time, dye concentration, adsorbent dose and pH. Adsorption depended on solution pH, dye concentration, carbon concentration and contact time. Equilibrium was attained at 165 minutes and 105 minutes for reac...

background and objectives: synthetic dyes are recalcitrant to degradation and toxic to different organisms. decolorization of textile wastewaters is one of the major concerns since last decades. physical-chemical treatments are very expensive and frequently producing large amounts of toxic wastes. biological treatments can be more convenient. in the present study, an attempt has been made for d...

background: there is unprecedented increase in the processing and packaging of many plant materials into food supplements, herbal medicine, skincare and cosmetic products for human needs. baphia nitida is used for topical skincare products. toluene, a toxic aromatic solvent, is increasingly being used in the production of these skincare and cosmetic products in many industries. this study asses...

Previous studies suggest that reactive dyes can induce IgE mediated bronchoconstrictions. To evaluate the significance of specific IgE and IgG antibodies in workers exposed to reactive dyes, we studied the prevalence of Black GR-specific IgG by enzyme linked immunosorbent assay, as well as Black GR-specific IgE by RAST, in 176 workers employed in 1 reactive dye factory and 4 neighboring factori...
