Abstract This work includes fabrication and electrical characterization of M etal/ I nterlayer/ S emiconductor (MIS) structures with methyl violet organic film on p- InP wafer. Metal(Ag)/ Interlayer (methyl =MV)/Semiconductor( p -InP) MIS structure presents a rectifying contact behavior. The values ideality factor ( n ) barrier height (BH) for the Ag/MV/ -InP diode by using current-voltage - V)...

Bisbenzimidazoles have a broad spectrum of potential applications: radioprotectors, drug delivery vectors, antiviral agents, etc. At the same time, they seem to be promising fluorescent probes for radiation measurements. Therefore, in present work, response X-ray irradiation Hoechst 33258, one most widely known representatives bisbenzimidazole family, was studied first time. Irradiation dye per...

Methylene blue, a prevalent cationic type dye, has been extensively utilized in textile industry. Lignin generates as byproduct and its utilization is required to add potential economic benefit of biorefinery process. Lignin-derived porous biochar, promising adsorbent, was propitiously prepared by chemical modification with different oxidation number manganese compounds (KMnO4, MnSO4, MnO2). Th...

The present study investigated the ability of modified shrimp shell by Polyethylenimine (PEI) for enhanced removal metanil yellow. modification was carried out using citric acid as a cross linker. yellow shell-PEI conducted batch method and some parameters affected adsorption including pH, initial dye concentration, contact time. optimum conditions were achieved at pH 5, concentration 1200 mg/L...

water plays a vital and essential role in our ecosystem. this natural resource is becoming scarce, making its availability a major social and economic concern. use of a large variety of synthetic dyes in textile industries has raised an hazardous environmental alert. about 17 - 20% of freshwater pollution is caused by textile effluents. these effluents are recalcitrant to biodegradation and cau...

Strains of Brucella melitensis biovars 1, 2, and 3 isolated in India, Italy, Kuwait, Saudi Arabia, the Federal Republic of Germany, and Zimbabwe were inhibited by thionin (20 micrograms/ml) but not by basic fuchsin (20 micrograms/ml) or safranin O (200 micrograms/ml). In other respects the strains were typical of their species and biovars. The existence of dye-sensitive strains of B. melitensis...

GFP and a FRET compatible dye were used to assess the influence of genetically encoded aryl azide positioning on Click chemistry-based protein conjugation. While modification efficiency of the sampled mutants using a strain promoted reaction varied by as much as ∼10 fold, there was no simple correlation with accessibility of the aryl azide on GFP's surface. One labeled GFP mutant (Gln204AzPhe) ...

Heparin and other acid mucopolysaccharides were extracted from various tissues by a modification of the method previously described (Bassiouni, 1953). The dye mucopolysaccharides complex obtained was resolved into its components with formamide: the acid mucopolysaccharides were precipitated with methyl alcohol in the presence of electrolyte (sodium chloride). A solution of the purified polysacc...
