Bandgap engineering has attracted increasing interest in the field of semiconductive materials with specific electrical and optical characteristics for various applications, such as solar energy harvesting, energy-related photocatalysts. Here, we propose a novel facile method to obtain combination type-II structure Ohmic contact by fabrication WO3/Ti-WOx/TiHyOz homo/heterojunction on WO3 photoc...

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...

In this study, microcrystalline cellulose (MCC) was modified to oxidized (OC), 6-deoxycellulose hydrazide and (N,N-diethyl)amine (MCC-Hyd MCC-DEM) derivatives employed as supporting material for the synthesis of copper nanoparticles (NPs). Copper ions from aqueous solution were adsorbed then reduced zero valent (ZVC) NPs using sodium borohydride on films prepared derivatives. The characterizati...
