Abstract Bismuth oxyhalides are becoming a promising contender for photovoltaic applications due to its non-toxic nature and decent optical properties. This study mainly deals with clarifying the effects of phase transformations on structure, optical, electrical properties BiOI thin film prepared via dip-successive ionic layer adsorption reaction (SILAR) method at different annealing temperatur...

Although bismuth chalcohalides, such as BiSI and BiSeI, have been recently attracting considerable attention as photovoltaic materials, the methods available to synthesize them are quite limited thus far. In this study, a novel, facile method to synthesize these chalcohalides, including BiSBr1-xIx solid solutions, at low temperatures was developed via the substitution of anions from O(2-) to S(...

TOUCAN is a Java application for the rapid discovery of significant cis-regulatory elements from sets of coexpressed or coregulated genes. Biologists can automatically (i) retrieve genes and intergenic regions, (ii) identify putative regulatory regions, (iii) score sequences for known transcription factor binding sites, (iv) identify candidate motifs for unknown binding sites, and (v) detect th...

Glycollate oxidase (glycollate:oxygen oxidoreductase, EC 1.1.3.1) from Pisum .f>ativum has an unusual absorption spectrum which suggests that the flavin N(3)-H function of the FMN coenzyme is ionized at pH 8.3. The enzyme is reduced rapidly by the substrate glycollate to yield a normal, reduced FMN coenzyme which is readily reoxidized by Oz. No evidence for the occurrence of covalent intermedia...

CPl is a sequence-specific DNA binding protein of yeast (Saccharomyces cerevisiae) which recognizes the highly fonserved A glement I (CDEI) of yeast centromeres. We cloned and sequenced the gene encoding CPl. The gene codes for a protein of molecular weight 39,400. When expressed in E. , i coli, the CPl gene directed the synthesis of a CDEI-binding protein having the same SDS gel mobilty as pur...

The cytochrome P450 OxyD from the balhimycin glycopeptide antibiotic biosynthetic operon of Amycolatopsis mediterranei is involved in the biosynthesis of the modified amino acid beta-R-hydroxytyrosine, an essential precursor for biosynthesis of the vancomycin-type aglycone. OxyD binds the substrate tyrosine not free in solution, but rather covalently linked to the carrier protein (CP) domain of...

MOTIVATION The transcriptional regulation of a metazoan gene depends on the cooperative action of multiple transcription factors that bind to cis-regulatory modules (CRMs) located in the neighborhood of the gene. By integrating multiple signals, CRMs confer an organism specific spatial and temporal rate of transcription. RESULTS Based on the hypothesis that genes that are needed in exactly th...

Cement-based materials modified with 3D BiOX (X = I, Cl) microspheres at different percentages (1, 5 and 10% by weight of the cement binder) were prepared to investigate durability photocatalytic NOx removal under outdoor conditions. Weathering—corresponding a period 13 months outdoors—was studied in terms NO efficiency visible UVA light irradiation for BiOI BiOCl mortars, respectively. Followi...
