The main objective of this research was to synthesize and characterize gold-coated Fe3O4 /SiO2 nanoshells for clinical applications. Magnetite nanoparticles (NPs) were prepared via co-precipitation. The results showed that smaller particles can be synthesized by decreasing the NaOH concentration, which in our case this corresponded to 35 nm by using 0.9 M of NaOH at 750 rpm. The NPs were then m...

This study reports an experimental investigation of pool boiling (PB) heat transfer performance hybrid (two types particles) and mono (single-particle) nanofluids consisting Boron nitride (BN) Silicon dioxide (SiO2) nanoparticles (NPs). While (HNFs) were prepared in a total particle concentration 0.05 vol.% with four different percentages these two NPs (are 0.01/0.04, 0.02/ 0.03, 0.03/0.02, 0.0...

Silica nanoparticles (SiO2 NPs) have been shown to exert cytotoxic effects in hepato-cytes and to cause liver injury. In the liver, Kupffer cells (KCs), as the resident macrophages, play an important role in the normal physiology and homeostasis of the liver. Nevertheless, few studies have attempted to clarify the role of KCs in hepatic injury induced by SiO(2) NPs. In this study, we treated Bu...

A green and easy technique was used to synthesize silver silica (Ag@SiO2) core–shell nanoparticles (NPs) in the matrix blend polymers matrix. Core–shell were loaded into polyvinyl alcohol (PVA) ultrahigh molecular weight polyethylene oxide (UHMW-PEO) blended polymer fabricate new nanocomposite films (NCFs) using developed solution-sonication-casting technique. The spectroscopic properties of re...

Background: In recent years, nanomaterials have been widely used in large quantities which make people be more frequently exposed to the chemically synthesized nanoparticles (NPs). When NPs are introduced into an organism, they may interact with a variety of cellular components with yet largely unknown pathological consequences. Objective: It was found that NPs enhance the rate of protein fi br...

For high-precision biochemical sensing, surface-enhanced Raman spectroscopy (SERS) has been demonstrated to be a highly sensitive spectroscopic analytical method and Ag is considered to be the best material for SERS performance. Due to the high surface activity of Ag nanoparticles, the high stability of Ag nanostructures, especially in moist environments, is one of the key issues that need to b...

Magnetite (Fe3O4) nanoparticles (NPs) and SiO2-coated Fe3O4 have successfully been synthesized using co-precipitation modified Stöber methods, respectively. The samples were characterized X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, high-resolution transmission electron microscopy (HRTEM), vibrating sample magnetometer (VSM) techniques, absorption spectroscopy (XAS),...

Polymer nanocomposites of polyaniline (PANI)-based metal oxides (SiO2, CeO2, and TiO2A) were synthesized by in situ chemical oxidative polymerization rapid mixing a hydrochloric acid medium to evaluate compare their performance as anti-corrosion coatings on commercial 1018 steel 3.5% NaCl medium. The developed dispersing an alkydalic resin (AR) for subsequent electrochemical characterization. X...

Oxidative stress is considered an etiological factor responsible for several symptoms of inflammatory bowel disease (IBD). In vitro anti-inflammatory activities of heat-killed Lactococcus lactis subsp. lactis BF3 have been reported. In this study, the anti-inflammatory effect of these cells was examined using a dextran sodium sulphate (DSS)-induced murine IBD model. Administration of heat-kille...
