Light-triggered reversible sorption of azo dyes on titanium xerogels with photo-switchable acetylacetonato anchors.

Photo-induced reversible sorption of azo dyes on titania xerogels is observed, which is based on the photo-switchable change of the acetylacetonato anchors in the xerogels. The photoisomerization of azo compounds that regulates many gate-keeper-like host-guest interaction systems is excluded as the determinant.

Rat skin carcinogenesis by topical applications of some azo dyes.

Groups of 6 male rats were painted twice weekly with 1 ml of a 0.2% solution of an azo dye in acetone. The dyes used were aminoazobenzene, 4-monomethylaminoazobenzene, their 3methoxy analogs, and 4-dimethylaminoazobenzene. In each case, all rats developed multiple skin tumors of histologie types similar to those found in rats treated with other chemical classes of carcinogen. 3-Methoxy-4-monome...

Molecular photo-oscillators based on highly accelerated heterocyclic azo dyes in nematic liquid crystals.

Benzothiazole-pyrrole-based azo dyes greatly enhance their thermal isomerisation rate by up to 160 times when they are under the influence of the nematic mean field yielding the LC-based photochromic oscillators with the highest oscillation frequencies reported so far (2.6 kHz at 298 K).

Decolorization of azo dyes (Direct Blue 151 and Direct Red 31) by moderately alkaliphilic bacterial consortium

Removal of synthetic dyes is one of the main challenges before releasing the wastes discharged by textile industries. Biodegradation of azo dyes by alkaliphilic bacterial consortium is one of the environmental-friendly methods used for the removal of dyes from textile effluents. Hence, this study presents isolation of a bacterial consortium from soil samples of saline environment and its use fo...
