Rhodamine B, a dye commonly used in a variety of biological studies was incorporated into the bodies of male tobacco budworm moths, Heliothis virescens (Lepidoptera: Noctuidae), by allowing them to feed freely on 0.1% rhodamine dissolved in a 10% sucrose solution. After exposing males for one to three days to this pigment, rhodamine was clearly detectable in >82% of spermatophores extracted fro...
A one-pot synthesis of 2,6-dibromodithieno[3,2-b;2',3'-d]thiophene (dibromo-DTT, 4) was developed. A key step was bromodecarboxylation of DTT-2,6-dicarboxylic acid, obtained by saponification of the diester 1. The donor-acceptor dye DAHTDTT (13), based on a central 2,6-bis[2'-(3'-hexylthienyl)]dithieno[3,2-b;2',3'-d]thiophene core (9), was prepared and incorporated in a dye-sensitized solar cel...
Of the five species of white rot fungi evaluated for their ability to decolorize Amaranth, Remazol Black B, Remazol Orange, Remazol Brilliant Blue, Reactive Blue, and Tropaeolin O in agar plates, Bjerkandera sp. BOS55, Phanerochaete chrysosporium, and Trametes versicolor displayed the greatest extent of decoloration. In static aqueous culture, the three cultures formed fungal mats which did not...
The dye disodium 3,4:3',4'-bibenzo[b]thiophene-2,2'-disulfonate can be used as a molecular probe for the fluorimetric detection of caffeine in aqueous solution. The fluorescence response is attributed to non-covalent interactions of caffeine with the dye in the ground state and in the excited state. The bimodal interaction allows performing ratiometric measurements with very good selectivity ov...
introduction: this study compared the apical sealing ability of a bioceramic based root canal repair filling material (iroot fs) with mineral trioxide aggregate (mta). methods and materials: forty single-canal teeth were prepared and randomly divided into two experimental groups ( n =18) and two control groups ( n =2). teeth in experimental groups were retrofilled with either mta or iroot fs. a...
Barium Oxide(BaO) nanoparticles were synthesized by simple co-precipitation method and were investigated by the catalytic activity of synthesized barium oxide nanopaticles was enumerated by epoxidation of styrene. The reaction was carried out and the product was obtained at higher efficiency. Particularly, the photocatalytic efficiency was estimated by degradation of Rhodamine-B (RhB) dye using...
Dye Sensitized Solar Cells (DSSCs) present a significant renewable energy source in terms of control different parameters governing flexibility, efficiency, lifetime and cost. The liquid electrolytes used inside the cells are generally responsible for leakage inefficient encapsulation related issues. These critical practical applications DSSCs. choice electrolyte medium cell should take into ac...
Due to our interest in the chemical space of organic dyes identify potential small-molecule inhibitors (SMIs) for protein-protein interactions (PPIs), we initiated a screen such compounds assess their inhibitory activity against interaction between SARS-CoV-2 spike protein and its cognate receptor ACE2, which is first critical step initiating viral attachment entry this coronavirus responsible ...
