Abstract Background and objectives: Hemin is a porphyrin compound derived from hemoglobin, the precursor of other porphyrin hemoglobin derivatives and the raw material of Hematin. Since hemin is widely used in medicine, we decided primarily to synthesize this substance in Laboratory and to determine the best way of hemin extraction from untransfused and expired blood units. Materials and Method...
As the field of nanotechnology advances, there is an increasing need for green nanomaterial identification devices. Recently, a few new studies have reminded us that as gets better and better, so will natural phenomena. we grow closer to finally reach nanoscale, it feasible physical expertise develop. Developments in future may allow technical advancements. It ability construct human constructs...
Using MnSO4 ̈H2O as manganese source and urea as nitrogen source, Mn/N co-doped TiO2 loaded on wood-based activated carbon fiber (Mn/Ti-N-WACF) was prepared by sol–gel method. Mn/Ti-N-WACF with different Mn doping contents was characterized by scanning electron microscopy, X-ray diffraction (XRD) and X-ray photoelectron spectroscopies (XPS), and ultraviolet-visible spectrophotometer. Results sho...
Gold Nanoparticles successfully applied for detection of Chlorpyrifos pesticide present in various water samples. Structural and morphological studies of Gold Nanoparticles were studied following UV-Visible Spectrophotometer, SEM and HRTEM. Trisodium Citrate has been used as a reducing agent. The author successfully applied Gold Nanoparticles capped with citrate ions for monitoring Chlorpyrifos...
The VOx/LUS-1 nanoporous silica synthesis and characterized by XRD, Nitrogen adsorption–desorption isotherms and UV-visible spectrophotometer. Direct oxidation of benzene to phenol in liquid phase by H2O2 peroxide were examined by using various (methanol, acetone, acetic acid, acetonitryl) solvents.
Biosynthesis of silver nanoparticles with small size and biostability is very important and used in various biomedical applications. In the present work, we describe the synthesis of silver nanoparticles (Ag-NPs) using seed aqueous extract of Olea europaea (Oe) and its antibacterial activity. UV–visible spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM), scan...
