This research investigates the removal of textile dyes (Rhodamine B and Alizarin Red S) from aqueous solution by a low-cost adsorbent prepared eggshell waste. Batch adsorption experiments were conducted in order to determine effect different parameters such as pH, dye concentration, contact time, dosage, particle <br /> size, temperature. The best correlation was found Langmuir model, max...

Mitochondria undergo dynamic fusion and fission events that affect the structure and function of these critical energy-producing cellular organelles. Defects in these dynamic processes have been implicated in a wide range of human diseases including ischemia, neurodegeneration, metabolic disease, and cancer. To provide new tools for imaging of mitochondria in vivo, we synthesized novel hydropho...

he objective of this study was to evaluate the influence of calcium hydroxide in intracanal dressing on the ability of the dyes rhodamine B and methylene blue to label the dentine. Forty extracted human mandibular premolars had their canals instrumented and were divided into four groups: in two groups, the canals were filled with a calcium hydroxide paste and the others remained in distilled wa...

Hypoxic stress is a risk factor of ocular neovascularization. Hypoxia visualization may provide clues regarding the underlying cause of angiogenesis. Recently, we developed a hypoxia-specific probe, protein transduction domain-oxygen-dependent degradation domain-HaloTag-Rhodamine (POH-Rhodamine). In this study, we observed the localization of HIF-1α proteins by immunohistochemistry and the fluo...

NiMn2O4 nanoparticles have been successfully prepared through sol-gel method. The effects of different factors such as the type of solvent, and amino acid temperature were investigated on the size and morphologies of products. The smallest particle size of NiMn2O4 nanoparticles was found to be 25 nm in diameter. The magnetic properties of the samples were also measured by an alternating gradien...

The presented study examines the phenomenon of the fluorescence under UV light excitation (312 nm) of E. coli cells expressing a novel metagenomic-derived putative methylthioadenosine phosphorylase gene, called rsfp, grown on LB agar supplemented with a fluorescent dye rhodamine B. For this purpose, an rsfp gene was cloned and expressed in an LMG194 E. coli strain using an arabinose promoter. T...

Four sorbicillinoids (1-4) and seven bisorbicillinoids (5-11), including two new compounds, 6-demethylsorbicillin (1) and 10,11-dihydrobisvertinolone (6), were isolated from a marine-derived fungus Trichoderma sp. Their cytotoxic activities against HL-60 cell line were evaluated by Sulforhodamine B (SRB) assay method and flow cytometric analysis.

the photocatalytic activity of nano-bi2o3 was evaluated in degradation of rhodamine b (rhb) as a model of dye pollutant from waste waters. nano sized bi2o3 was synthesized using the chemical precipitation method. the as-prepared sample was characterized by x-ray diffraction (xrd), scanning electron microscopy (sem) and fourier transform infrared spectrometry (ft-ir). structural analysis reveale...

We have fabricated ZnO nano rods by hydrothermal method and successively doped them with tin (Sn) using different concentrations of 25, 50, 75 100 mg chloride. XRD the structures showed that possess hexagonal wurtzite phase. Scanning electron microscopy (SEM) was used to explore morphology it shows nanorod like for all samples no considerable change in structural features were found. The dimens...
