Abstract Over the last few decades, the applications of nanotechnology in medicine have been extensively explored in many medical areas, especially in drug delivery. Nanotechnology concerns the understanding and control of matters in the 1-100 nm range, at which scale materials have unique physicochemical properties including ultra-small size, large surface to mass ratio, high reactivity and unique interactions with biological systems [1]. Drug-loaded nanoparticles can be achieved through phy...
Abstract A sample of Citrullus colocynthis fruits were collected from Alamab Area South Khartoum state, the seeds were isolated after dryness of the fruits. Phytochemical screening of the seeds indicate that they contain of flavonoids, tannins, cumarins , sterol, triterpene, saponins and Alkaloids. The oil of Citrullus colocynthis was extracted from the seeds. The average yield was 20%. Physico-chemical characterization result show that the density of the oil was 0.9728 g/cm3, Iodine value ...
Abstract In this research, the corrosion behavior of the copper and copper alloy in different conditions and environment were studied. The corrosion behaviour and mechanism for copper and copper alloy in( HNO3, H2SO4,HCl, NaCl)solutions were studied by chemical mass loss, kinetic of corrosion, half life time, inhibitor efficiency and corrosion rate of inhibitor efficiency methods at25oC.were also investigated. The chemical results revealed that copper and copper alloy corrodes in( HNO3, H...
ABSTRACT Unique properties of silver (Ag) and its allied nanoparticles are of great interest in the fields of chemistry and technology. However, the widespread applications of nanoparticles call for synthesis routes involving eco-friendly procedures. Silver nanoparticles (Ag NPs) and their hybrids nanoparticles (Ag-Ni and Ag-Co) were synthesized using locally available biodiversity plants as alternative method to the expensive and toxic chemicals previously used. Fresh plants were collected ...
Abstract This study focuses on determine of the percent of carboxymethyl cellulose in ice-cream stabilizer which has been used under the number E466 it was determined to be 98.92%. First the percent of sodium chloride determined by Volhard method it was found to be 0.48% then freeflycolate were determined by U.V spectroscopic method the percent was found to be 0.59%. Finally the degree of substitution Ds were determined gravimetrically it was found 0.2. FT-IR spectroscopy also were used to ...
Abstract This study was conducted to treat the Sudanese crude oil from Rawat area southwest of Kosti which has a high wax content of 26.3% by weight and pour point 54°C, in order to remove the wax and to reduce the pour point and enhance the physical and molecular properties of the treated oil using organic solvent de-waxing technology. The physical and molecular properties of crude oil and the oils produced from the treatments were obtained using American Society for Testing and Materials ...
