DNA carries genetic information in its sequence of bases. Synthetic oligonucleotides that can sequence-specifically recognize a target gene sequence are a useful tool for regulating gene expression or detecting target genes. Among the many synthetic oligonucleotides, tail-clamp peptide nucleic acid (TC-PNA) offers advantages since it has two homopyrimidine PNA strands connected via a flexible e...

One of the most reliable renewable energy source is solar from sun. However, materials have been unable to meet their potentials as a good absorber layer in thin films. Most recently, Cu2ZnSnS4 (CZTS) identified layer, yet same problem persists. In this study, we examined depletion capacitance vis-a-vis voltage and range frequencies based on heterojunction types structures. The modeled cell con...

Azo-functionalized MOPs (Azo-MOPs) were synthesized via oxidative polymerization of aromatic amines catalyzed by t-BuOCl/NaI (25 °C, 1 h, yield: >95%), which displayed an excellent coordinating ability with a Ru complex. The resulting Ru-coordinated Azo-MOPs displayed high CO2 capacity and high performances for catalyzing the methylation of amines with CO2 under low pressure (0.5 MPa).

BACKGROUND Simultaneous contact allergies to Disperse Orange 1, 4-nitroaniline and p-aminodiphenylamine (PADPA), as well as to other disperse azo dyes and to p-phenylenediamine (PPD), have been reported. Cross-reactivity is one of the possible explanations for simultaneous reactions between PPD and disperse azo dyes. Some metabolites from the azo reduction of these disperse azo dyes could be se...

In this study, the optimization of working cathode position in sleeve-type bioelectrochemical system (BES) was evaluated with inner/outer chamber for azo dye decolorization. Results showed that the working position in outer chamber performed better with decolorization efficiencies of 97.8 ± 2.1% (7h) and 94.0 ± 2.3% (16 h) than that in inner chamber as the volume ratio Vcathode:Vanode=1:1 and 3...

I N 1939, Bi’atton and Marsimall (1) described a niethod for the quantitative ammalysis of sulfoimamides by coupling their diazonium salts with N-(1-naphthyl)-etimylenediamine to form an azo dye. Since then, the procedure has been used extensively for the determination of sulfonamide compounds jim blood ammd urine (2). Recently an occasion arose for the qualitative identification of sulfonamide...

We synthesized the five compounds of azo bridged ethoxybenzothiazole substituted phenyl ester derivatives by using Dicyclo Hexyl Carbodiimide (DCC) and a catalytic amount of Dimethyl amino pyridine (DMAP) as a nucleophile. All the compounds structures were confirmed by IR, NMR and mass spectrum. The synthesized compounds were screened for antioxidant property by DPPH radical scavenging method. ...

In the crystal structure of the title compound, C23H19N5O3·0.58C2H6OS·0.42C2H3N, prepared by the azo coupling of the 4-nitro-phenyl-diazo-nium salt with 3a-(p-tol-yl)-2,3,3a,4-tetra-hydro-1H-benzo[d]pyrrolo-[1,2-a]imidazol-1-one, the azo mol-ecules are linked by N-H⋯O hydrogen bonds into chains along the a-axis direction, and by the π-π inter-action into [101] chains. The dimethyl sulfoxide and...

The title compound, C(16)H(11)N(3)O(2), displays a trans configuration with respect to the azo group. The mol-ecule is non-planar; the maleimide ring forms a dihedral angle of 42.35 (4)° with the benzene ring bonded to its N atom and the mean plane of this benzene ring is rotated by 21.46 (8)° with respect to the azo group mean plane, which, in turn, forms a dihedral angle of 24.48 (7)° with th...

The photoinduced alignment of a liquid crystal (LC) on films of azo dyes was studied for the liquid crystal display applications. In order to improve the alignment stability of the photoaligned dye (SD-1), the azo-dye derivative with polymerizable terminal groups was synthesized (SDA-1). The films of SDA-1 exhibit good photoalignment properties and ultraviolet stability after thermal polymeriza...
