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...

UNLABELLED Photon harvesting by reducing reflection loss is the basis of photovoltaic devices. Here, we show the efficacy of Al-doped ZnO (AZO) overlayer on ion beam-synthesized nanofaceted silicon for suppressing reflection loss. In particular, we demonstrate thickness-dependent tunable antireflection (AR) from conformally grown AZO layer, showing a systematic shift in the reflection minima fr...

In this paper, the transparent conductive aluminum-doped zinc oxide (ZnO: Al, AZO) thin films with different annealing conditions are studied. The AZO thin films were prepared on the Coring glass substrate by RF magnetron sputtering. The AZO thin films were annealed in atmosphere of vacuum and hydrogen at temperatures from 100 to 400°C in steps of 100°C for 1 min, respectively, to investigate t...

The contact resistance between source/drain electrodes and semiconductor layer is an important parameter affecting electron transporting performance in the thin film transistor (TFT). In this work, we introduced a transparent and the solution prossable single-walled carbon nanotube (SWCNT)/Al-doped ZnO nano particle (AZO NP) bilayer electrodes showing low contact resistance with indium-oxide (I...

As transparent heated films (THFs) based on conductive oxides (TCOs) are restricted by expensive raw materials and inappropriate fabricating film curved surfaces because of its brittleness, silver nanowires (AgWS-TCF) is an ideal alternative material for THF. However, there still many problems to be solved in the electrical thermal stability AgNWs-TCF. In this paper, Al-doped ZnO (AZO) nanopart...

New carbene-generating photolabile bile salt derivatives, 3,3-azo-7 alpha,12 alpha-dihydroxy-5 beta [7 beta-3H]cholan-24-oic acid and (3,3-azo-7 alpha,12 alpha-dihydroxy-5 beta [7 beta-3H]cholan-24-oyl)-2- aminoethanesulfonic acid were synthesized with high specific radioactivity. These 3-diazirine-derivatives could be activated to the corresponding carbenes by irradiation with ultraviolet ligh...

As we all know, transparent and conductive Al:ZnO (AZO) films are being considered for manufacturing transparent electrodes in flat panel displays, solar cells and organic light emitting diodes due to their high electro optical quality, high material availability and low material cost for large area applications. In this experiment, AZO thin films were prepared on glass substrate by Magnetron S...

Degradation of dyes is an important environmental issue. In order to avoid the carcinogenic risks in anaerobic-aerobic biological process for wastewater containing azo dyes, a hemin based biomimetic oxidative degradation of azo dyes was developed. Acid orange 7 (AO7) was selected as the model for azo dye and the high efficient degradation was achieved in hemin/H2O2 system at pH 11.0. Degradatio...

Azoreductases have been characterized as enzymes that can decolorize azo dyes by reducing azo groups. In this study, genes encoding proteins having homology with the azoreductase gene of Bacillus sp. OY1-2 were obtained from Bacillus subtilis ATCC6633, B. subtilis ISW1214, and Geobacillus stearotherophilus IFO13737 by polymerase chain reaction. All three genes encoded proteins with 174 amino ac...

Azo dyes are commonly used in many commercial industries. Some of the azo dyes can produce carcinogenic compounds after being metabolized by azoreductase. Several human intestinal microbiota possess azoreductase activity which plays an important role in the toxicity and mutagenicity of these azo dye compounds. The acpD gene product (AzoEf1) responsible for the azoreductase activity of Enterococ...
