Abstract Metal complexes of Mn(II), Cu(II) and Ni(II) with Schiff base ligand (HL) derived from condensation of propionaldehyde with ethylenediamine were synthesized in alcoholic medium. The complexes were characterized on the basis of melting point, conductivity, solubility, IR and UV/Visible spectral studies. The in-vitro antibacterial activities of the complexes were tested against different strains of […]
Synthesis, Spectral Characterization and Antimicrobial Activity of Some Metal Complexes of Mixed Antibiotics
Abstract Mixture of cephalexin (Cep) and amoxicillin (amx) in 1:1 mole ratio, interact with transition metal ions to give [M(cep)(amx)].3H2O complexes in 1:1:1 mole ratio, where M = Co(II), Ni(II), Zn(II) and Fe(III). The complexes were characterized by physicochemical and spectroscopic analysis. The UV/Vis spectral data suggestedan octahedral geometry for Co(II), Ni(II) and Fe(III) structures, […]
The real structure of H3+ is angular
Abstract In the present communication, an attempt to clarify what is the real structure of the pivotal interstellar ion H3+ is conducted. Calculations were performed for three H3+ structures: the “traditional” equilateral triangular and linear ones, as well as an angular structure. Based on the Gθ andSθ values, it is proposed that the real (most […]
Different spectrophotometric methods for determination of miconazole nitrate and hydrocortisone in bulk and in topical pharmaceutical preparation without prior separation
Abstract Three simple, accurate, sensitive, selective and cost effective spectrophotometric methods were developed and validated for quantitative determination of miconazole nitrate (MIC) and hydrocortisone (HDC) in pure form, laboratory prepared mixtures and topical pharmaceutical preparation without any preliminary separation step. HDC was determined directly at λmax 242.6 nm in the presence of MIC, while MIC […]
Spectrophotometric study of the interaction between a novel benzothiazolethioglycoside as antimicrobial agent with bovine serum albumin
Abstract This study is concerned with the interaction of a newly synthesized antimicrobial agent (BTT) with bovine serum albumin (BSA). BTT is a novel benzothiazolethioglycosides that was prepared via reaction of the benzothiazole and 2-thioxoimidazolidin-4-one thiolate salts with tri- acetylated cyclic xylopyranosyl bromide. It was tested for antimicrobial activity against different bacteria and fungi and […]
Phytochemical Screening and Antibacterial Activity of Cultivated Medicinal Plants Citrus paradisi
Abstract Fruits are the main fruit trees grown throughout the world and are well–appreciated for their refreshing juice and health benefits. This study of Citrus paradisi (peels) of hexane, acetone and methanol extracts was carried out to show phytochemical screening and antibacterial activity. Plants and plant products are continuously being explored in medicine against the […]
Phytochemical, Proximate Composition and Minerals contents of Moringa oleifera
Abstract The aim of the present study was to evaluate the proximate composition, phytochemicals, and minerals contents of Moringa oleifera seeds, family Moringaceae. The proximate analysis reveal the dry matter 94.60%, ash content 2.13 %, crude protein 58.32 %, oil 11.3 %, crude fiber 4.75 % and total carbohydrate content is 23.5%. The phytochemicals analysis […]
An Insight on Cooperative Binding of Food Coloring Allura Red AC with Bio Macromolecule
Abstract In this study, interaction of a food colouring such as Allura Red AC with Bovine Serum Albumin (BSA) biomacromolecule in 5 mM phosphate buffer, pH=7 was studied by absorption spectroscopy, competitive binding and thermodynamic study. The binding isotherm, binding capacity and Scat chard plots were plotted at various temperatures. The binding constant obtained from […]
A Concept: Improved Hydrogen Production using Pt-N-TiO2 under Visible Light via Photocatalysis Process
Abstract The demand of energy in Indonesia is still dominated by the use of fossil fuels. In 2013, fossil fuels contributed 94.3 percent of the total energy. However, production of fossil fuels: coal, oil, and gas has been decreasing very significantly. Additionally, high energy requirements has not been matched with an equitable electrification ratio throughout […]
Impact of Anthropogenic Activities on Metal Load of Sagbama River, Niger Delta Region of Nigeria
Abstract Impact of anthropogenic activities on metal load of Sagbama River was investigated. Water samples were obtained at four (4) designated locations namely: Sagbama, Patani, Odi and Toru-Orua along Sagbama River in Bayelsa State, Nigeria. Standard procedures were employed for the collection and treatment of water samples. Samples collected were analysed using spectrophotometric methods for […]
