Abstract The current research work investigated the photocatalytic degradation of dye using polythiophene-based silver-doped zinc sulfide (PT/Ag-ZnS). The ternary composite was synthesized by in-situ chemical oxidation polymerization approach and thoroughly characterized. Maximum photocatalytic activity depicted > 80% for Ag-ZnS and > 94% for PT/Ag-ZnS at pH 7 and 4 respectively at 10 mM oxidant and 30 mg/100 mL catalyst dose, 10 ppm IDC under 90 min. DMSO serves as an effective radical scavenger. The novel polymeric composite exhibits efficient reusability upto five cycles. Pseudo 1^st -order kinetic model was best fitted for PT/Ag-ZnS. Toxicity analysis gave a More >

Abstract Poly-3,4-ethylenedioxythiophene: polystyrene sulfonate (PEDOT/PSS) has revolutionized the field of smart textiles as an advanced conductive polymer, offering an unprecedented combination of high electrical conductivity, solution processability, and mechanical conformability. Despite extensive research in PEDOT/PSS-coated fabrics over the past decade, a critical challenge remains in finding the delicate balance between enhanced conductivity and washing durability required for real-world wearable applications. Hence, this study investigates the electrical conductivity and durability properties of PEDOT/PSS-based conductive fabrics for wearable electronics. By carefully controlling the doping concentration of dimethyl sulfoxide (DMSO), an optimal conductivity of 8.44 ± 0.21 × 10⁻³ S… More >

Abstract In this article, we study different molecular structures such as Polythiophene network, for and , Orthosilicate (Nesosilicate) , Pyrosilicates (Sorosilicates) , Chain silicates (Pyroxenes), and Cyclic silicates (Ring Silicates) for their cardinalities, chromatic numbers, graph variations, eigenvalues obtained from the adjacency matrices which are square matrices in order and their corresponding characteristics polynomials. We convert the general structures of these chemical networks in to mathematical graphical structures. We transform the molecular structures of these chemical networks which are mentioned above, into a simple and undirected planar graph and sketch them with various techniques of mathematics.… More >

Abstract The relevance of Retinoic acid receptor-related orphan receptors in cancer progression has sparked interest in developing multifunctional therapeutics. In the search for potentially active novel compounds with anticancer characteristics, the Gewald reaction was employed to develop different thiophene derivatives (8a–8i). Physicochemical and spectroanalytical investigations verified the molecular structures of the synthesized derivatives. Using an in vitro primary anticancer assay, NCI chose all of the synthesized molecules as prototypes and assessed their anticancer efficacy against a panel of various cancer cell lines representing nine distinct neoplasms. The compounds were found to have a wide range of anticancer… More >
