A maximum efficiency of 17 % for ultra-thin n-type AZO layer and 17.5 TiO2 based silicon heterojunction solar cell is reported by optimizing its properties which much higher than practically obtained signifying a lot improvements can be performed to improve TiO2/Si AZO/Si cell. used as emitter crystalline wafer p-type (p-cSi) modelling heterojunctions respectively using AFORS HET automat simula...

PRESENT METHODS for the determination of magnesium in biologic fluids and their inadequacies have been reviewed by Maclntyre and Wootton (1). In 1957, Mann and Yoe (2) introduced a color reagent for magnesium called Magon, 1-azo-2-hydroxy-3-(2,4-dimethylcarboxanilido )naphthalene-1’(2-hydroxybenzene), which they reported has a sensitivity 8 times greater than that of Titan yellow. Since then, M...

Zinc oxide (ZnO) photocatalysts were synthesized by sol-gel method using zinc acetate as precursor for degradation of azo dyes under UV irradiation. The resultant samples were characterized by different techniques, such as XRD, SEM, and EDX. The influence of preparation conditions such as calcination temperature and composite ratio on the degradation of methyl orange (MO) was investigated. ZnO ...

A series of linear and macrocyclic peptides 3-12 were synthesized using 3,5-pyridinedicarboxylic acid (1) as starting material and screened for their antimicrobial, anti-inflammatory and anticancer activities. Bis-ester 3 was prepared from 1 and L-leucine methyl ester. Hydrazinolysis and hydrolysis of dipeptide methyl ester 3 with hydrazine hydrate or 1 N sodium hydroxide afforded compounds 4 a...

By 1935, various investigators (9) principally Kinosita and his co-workers had established the hepato-carcinogenic activity of o-aminoazotoluene and N,N-dimethyl-p-aminoazobenzene. These azo dyes, administered in the diet or by subcutaneous injection, elicit changes--including neoplasms--in the livers of rats and mice and perhaps in the livers of other species. Subsequently it was established t...

The environmental challenge of synthetic azo dyes is of increasing concern due to the serious health effects on animals and human being. Metanil yellow (monosodium salt of 4-m-sulphophenylazodiphenylamine) was selected as the model compounds for this study because of its wide application in various textile industries either as such or in combinations with some other dyes as color additives. The...

2-Amino-1,3-benzothiazole was synthesized and schiff bases were prepared by reacting a series of aromatic aldehydes with 2-amino-1,3-benzothiazole to form a number of potentially biologically active compounds. Azo dyes of 2-amino-1,3-benzothiazole were synthesized by reacting various aromatic amines , substituted amines and phenols. The structures of 2-amino-1,3-benzothiazole, Schiff bases and ...

We present a novel approach to reversibly control the assembly of liposomes through an anchored multistimuli responsive DNA oligonucleotide decorated with an azobenzene moiety (AZO-ON1). We show that liposomes assembly can be simultaneously controlled by three external stimuli: light, Mg(2+), and temperature. (i) Light alters the interaction of AZO-ON1 with liposomes, which influences DNA coati...
