The multifaceted pathophysiology of diabetic wounds coupled with impaired diabetic wound healing remains a significant challenge for the medical community in the 21st century. Possibility of bacterial infections, insufficient vascular supply, increment in levels of oxidative stress, and abnormalities in defenses mechanism of antioxidant causes diabetic foot ulcers (DFU) that leads to significant morbidity. An […]
The present work is an experimental study of steady state convective heat transfer of de-ionized water with a (0.04% by volume) volume fraction of Al2O3 nanoparticles dispersed to form a nanofluid that flows through an aluminium tube.Laminar fully developed flow heat transfer coefficient of Al2O3 nanoparticles are dispersed in water in circular tube is discussed […]
Nano dithiocarbamate (DTC) complex have been prepared by reaction between dithiocarbamate and metal salt under ultrasound irradiation. Reaction conditions such as the ligand DTC and phennantroline concentration, aging time and the ultrasonic device power show important roles in the size, morphology and growth process of the final products. The dithiocarbamate complex nanoparticles have been prepared […]
The aim of this study was to investigate the sol gel synthesis of HA/FA nanoparticles and the possible formation of TCP phase or unstoichiometric calcium deficient hydroxyapatite (CDHA) from the precursors with a Ca/P ratio of 1.62. In order to prepare the sol, the solutions of Triethyl phosphite, ammonium fluoride and calcium nitrate in ethanol […]
Nanotechnology has slowly but steadily revolutionized the diagnosis, imaging and treatment of cancer. Detecting cancer at earliest stages, locating the tumor at different areas in the body and specific delivery of the drugs to malignant cells including surgically inaccessible tumors are the core areas of medical and pharmaceutical research across the world. In this endeavour, […]
In this article, ZnO and ZnO:Mn nanoparticles prepared by reverse micelle method. The various crystalline properties of these nanoparticles such as size, d-spacing, strain, stress, dislocation density and texture coefficient have been calculated with the help of XRD spectrum. The XRD results indicated that the synthesized ZnO and ZnO:Mn nanoparticles have a pure wurtzite (hexagonal […]
The aim of the present study was to prepare nano-sized calcium fluoride (CaF2). Calcium fluoride nanoparticles were synthesized by CaCl2.6H2O and ammonium fluoride. Nanoparticles were synthesized by co-precipitation method. The synthesized nanocrystals were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM). The crystallite size estimated using Scherer’s formula was […]
Calcium fluoride nanoparticles with special amount of cerium ion (%1) were synthesized by coprecipitation. Fourier transforms infrared spectroscopy (FTIR), X-ray diffraction (XRD), absorption and photoluminescence (PL) from CaF2Ce nanoparticles has been investigated. FTIR spectra reveal that there are some amounts of OH, NO3 and other organic functional groups on the particle surfaces before the post […]
In this paper, a novel method of producing bi-metallic alloy nanoparticles at low temperatures using hydrogen bombardment of thin films, deposited on glass substrates, is introduced. Optical and morphological characteristics of the nanoparticles were extensively studied for various conditions of plasma treatment, such as plasma power density, temperature, duration of hydrogen bombardment, thickness of the […]
A new mixed halo chromate nanoparticle compound was synthesised and characterized. Triphenylphosphonium trifluoroiodochromate (III)[P(C6H5)3H]+[CrF3I]– nanoparticle was synthesized by using triphenylphosphonium iodide reaction with CrF3, in the presence of 3-mercaptopropionic acid. This method is a simple and direct method. The product was characterized by spectroscopic and analytical methods such as 31P-NMR, FT-IR, XRD, SEM. Theoretical calculations […]
