Bovine serum albumin (BSA) nanoparticles loaded with paclitaxel (PTX) were prepared using a desolvation technique. A 32 full factorial design (FFD) was employed to formulate nanoparticles. Nanoparticles were characterized for particle size by photon correlation spectroscopy and surface morphology by scanning electron…
In this paper, the possibility of removing impurities during magnesium recycling with pyrometallurgical techniques has been evaluated by using a thermodynamic analysis. For 25 different elements that are likely to be contained in industrial magnesium alloys, the equilibrium distribution ratios between the metal, slag…
A first-principles computational tensile test has been preformed to investigate the effects of hydrogen on a tungsten grain boundary. It has been found that the maximum ideal tensile strength of the tungsten grain boundary with hydrogen atom segregation was 32.85 GPa, which was about 9% lower than that of the clean tu…
We have studied the generation mechanisms of two different radiation-induced point defects, the Ge(1) and Ge(2) centers, in a germanosilicate fiber and in its original preform. The samples have been investigated before and after X-ray irradiation using the confocal microscopy luminescence and the electron paramagnetic…
The future of nanomedicines is undermined by the lack of financial profitability, consumer distrust, ineffective regulation of new and generic products, weak patent protection and insurance market failure. Its economic breakthrough is dependent on a series of countervailing measures and actions. Success requires more…
Amino functional mesoporous silica SBA-15 materials have been prepared as efficient adsorbents for halophenols in wastewater. The organic-inorganic hybrid material was obtained using successive grafting procedures of SBA-15 silica with 3-aminopropyl-trimethoxysilane (NH2-SBA-15). The comparison of adsorption of haloph…
The present study investigates the magnetic properties of spherical monodispersed maghemite (γ-Fe2O3) nanoparticles coated with multiple silica (SiO2) layers of different thicknesses, forming core-shell multifunctional nanomaterials. This study was performed using a combination of local probe techniques (Mössbauer spe…
We have studied the strain field around the 90° domains and misfit dislocations in PbTiO3/SrTiO3 (001) epitaxial thin films, at the nanoscale, using the geometric phase analysis (GPA) combined with high-resolution transmission electron microscopy (HRTEM) and high-angle annular dark field––scanning transmission electro…
Self-assembled amphiphilic graft copolymers in aqueous solution to form polymeric micelles, have received growing scientific attention over the years. Among the polymeric micelles, hydrophobicized polysaccharides have currently become one of the hottest researches in the field of drug delivery nanosystems. It is attri…
The effect of poly(methyl methacrylate) modified water hyacinth fiber on properties of low density polyethylene (LDPE)/natural rubber (NR)/water hyacinth fiber (WHF) composites were investigated. The composites were prepared with Z-blade mixer at 180°C and rotor speed of 50 rpm. The poly(methyl methacrylate) modified…
In this paper, we report a study of using cholesteric liquid crystals (CLCs) doped with dodecylamine for detecting aldehyde vapors. CLCs doped with dodecylamine show color change from red to yellow-green upon exposure to 300 ppmv pentyl aldehyde within 60 s. In contrast, no colorimetric response is observed when pure…
A library of 120 nanoparticle conjugates is produced by simple one-pot thiol exchange reactions. The antibiotic activity of the conjugates toward Staphylococcus aureus is found to depend upon the combination of thiols assembled on the nanoparticles.
Since the beginning of 21st Century, scientists and engineers have been investigating triboluminescent materials for use in smart impact sensors. One of the brightest triboluminescent materials found thus far is europium dibenzoylmethide triethylammonium (EuD4TEA). This material was discovered by Hurt in 1966 and is b…
While most ceramics are composed of ubiquitous elements (the ten most abundant elements within the Earth's crust), many advanced materials are based on rare elements. A 'rare-element crisis' is approaching owing to the imbalance between the limited supply of rare elements and the increasing demand. Therefore, we propo…
The corrosion behavior of titanium alloy without vanadium Ti-6Al-7Nb under simulated biological conditions was investigated and compared with that of titanium and Ti-6Al-4V alloy, which employed as biomaterials. The aim of the present study was to evaluate their corrosion performance through the analysis of open circu…
Fe3O4 magnetic nanoparticles (Fe3O4 MNPs) were successfully prepared through an advanced reverse co-precipitation method under the assistance of ultrasound irradiation. The structure and size distribution were characterized by X-ray powder diffraction (XRD), laser particle size analyzer (LPSA), Fourier transform infra…
We report on spatially resolved electron energy-loss spectroscopy studies of optical modes in individual star-shaped gold nanoparticles. We studied different morphologies, ranging from a spheroid to well-developed nanostars. For each shape, essentially two groups of modes are appearing: the first one is localized arou…
The nanomaterials have important application in different field of science such as biology and pharmacology, which draws the attention of biologists towards this field of study more than before. As the worldwide mortality rate is high due to the pathogens and especially because of the bacteria associated dysenteriae a…
MWCNTs reinforced SiR nanocomposites were prepared through a high-shear mechanical mixing technique, using DCP as a curing agent. Under optimum conditions, the MWCNTs can be dispersed homogeneously in the SiR matrix to improve the mechanical properties of the nanocomposites. The mechanical properties of the nanocompos…
Amorphous As2Se3 chalcogenide thin film was exposed to UV light (i line and g line) using mercury lamp for 30 min. XRD, UV/VIS spectroscopy and thickness measurements were taken for unexposed and exposed thin film for structural and optical characterizations. Linear optical constants (linear refractive index, extincti…
