conclusions our successful extraction of purified lps from e. coli isolates of uti patients’ urine samples can be an important step to understand the uti disease conditions. results the silver-stained gel demonstrated both smooth and rough type lps by showing trail-like band patterns with the presence and lacking o-antigen region, respectively. coomassie blue staining showed no band assuring th...
Background: Since heavy metals can accumulate in the tissues of aquatic organisms, they can cause a range of hazardous effects which can become harmful to humans. The aim of this study was to investigate the acute effects of some heavy metals as potential dangerous substances by assessing the mortality effects of Mercuric Chloride (HgCl2), Lead Chloride (PbCl2) and Zinc Sulfate (ZnSO4) pollutan...
Morphology is a primary part of designing metal nanocrystals and nanomaterials with controlled functional properties. Here, we demonstrate the potential of foreign sulfate ions to tune the silver dendrites to highly branched chains through a simple galvanic replacement reaction without introducing any organic surfactants. We further illustrate the underlying mechanism according to diffusion-lim...
The kinetics and mechanism of the reaction between dissolved oxygen and sulfur(iv) was studied in aqueous acidic medium using co-catalysts peroxodisulfate and silver(i) ions. The presence of both catalysts was required to observe measurable rates in the studied process. The reaction rate was determined through following the UV-absorption of hydrated sulfur dioxide, and the trends were determine...
Silver doped hydroxyapatite was prepared by the precipitation method, using the precursor of hydroxyapatite, CaCl2-0.5M and (NH4) 2HPO4-0.3M; silver sulfate (Ag2SO4) is added to the precursors in order to bring the ions of silver (Ag at 10%) in the structure of hydroxyapatite. The morphology, structure and composition of prepared samples were characterized by X-ray diffraction, the complex ther...
In this article, the efficiency of microwave pretreatment, which is an environmentally friendly, low-energy consuming method for recovery from refractory gold-silver ores, was investigated. The ore sample belonged to oxidized Bolkardağ deposit, contains carbonate (calcite, dolomite, smithsonite, hydrozincite), silicate (quartz, hemimorphite), sulfate (beudantite, plumbo-jarosite), and iron oxy/...
silver nano-particles have different biological applications due to their compatibility. chemical methodsusually result in remaining some amounts of toxic reactions on the nano-particles. for this reason, the useof plants as sustainable and accessible resources in preparation of compatible nano-particles has attracteda lot of attention in the recent years. this research investigated the green s...
3,4-Dialkoxyphenylpyridine complexes with silver dodecyl sulfate or triflate are liquid crystalline. The polycatenar and show one both of a cubic columnar hexagonal phase depending on the chain length dialkoxyphenylpyridine anion associated silver. Their mesomorphism is compared analogous very well-studied dialkoxystilbazole ligands as well closely related N-phenylpyridinium analogues. slightly...
