In continuing studies of drugs against Mycobacterium leprae in mice we have tested the following compounds: lincomycin, clinimycin (7( S ) -chloro-7 -deoxylincomycin, clindamycin) , U-24729A (4' -pentylN -demethyl-7 -chlorolincomycin), amicetin, phosphonomycin, ABT-29666 (1-{3-[ 4-(pchlorophenyl-azo )-5, 6, 7, 8-tetrahydro-1naphthylamino] propyl} piperidine), ABT38396 (1{3-[ 4-( 6-methoxy-3-pyr...

A high-performance flexible conductive substrate is one of the key components for developing promising wearable devices. Concerning this, a sustainable, flexible, transparent, and cellulose/ZnO/AZO (CZA) film was developed in this study. The cellulose used as transparent substrate. added AZO layer ZnO functioned an interface buffer layer. Results showed that effectively alleviated intrinsic inc...

We report the effect of a disperse carbon interlayer between the n-a-Si:H layer and an aluminium zinc oxide (AZO) back contact on the performance of amorphous silicon solar cells. Carbon was incorporated to the AZO film as revealed by x-ray photoelectron spectroscopy and energy-dispersive x-ray analysis. Solar cells fabricated on glass substrates using AZO in the back contact performed better w...

Trametes villosa laccase was used for direct azo dye degradation, and the reaction products that accumulated after 72 h of incubation were analyzed. Liquid chromatography-mass spectrometry (LC-MS) analysis showed the formation of phenolic compounds during the dye oxidation process as well as a large amount of polymerized products that retain azo group integrity. The amino-phenol reactions were ...

The generation of surface anisotropy by photochemical means has been proposed as an attractive method to align liquid crystals. In this paper, we present an experimental study of the alignment induced on a liquid crystal by a polymer film containing azo-dye groups in the side chain. Optical measurements were performed in nematic liquid crystal cells to determine the azimuthal and zenithal ancho...

Evidence that the reticulo-endothelial system (R.E.S.) may be involved in the carcinogenic proc ess has been presented by Stern and Willheim (22) and by Jaffe (11). This system has also been im plicated in the metabolism of certain fat-soluble materials such as Vitamin A (3,10,17) and choles terol (3, 23) and the water-soluble vitamin, riboflavin (2, 9, 10). Since riboflavin is a factor in the ...

the main theme to conduct present research work was to evaluate the effect of anaerobic granular sludge in degradation of two azo dyes. the study was evaluated in batch experiments where anaerobic and aerobic conditions were integrated by exposing anaerobic granular sludge to oxygen. under these conditions, the azo dyes were reduced, resulting in a temporal accumulation of aromatic amines. subs...

Zeonor plastics are highly versatile due to exceptional optical and mechanical properties which make them the choice material in many novel applications. For potential use in flexible transparent optoelectronic applications, we have investigated Zeonor plastics as flexible substrates for the deposition of highly transparent ZnO and AZO thin films. Films were prepared by pulsed laser deposition ...

The first paper of this series (1) reported the results of tests of the carcinogenic activity of cer tam analogs of p-dimethylaminoazobenzene (DAB) in which a pyridine ring or a thiazole ring replaced one of the benzene rings of DAB. Due to the presence of the hetero atom or atoms, position isomers are possible in the heterocyclic analogs, and some of these isomers were synthesized and tested. ...
