Collagen and elastin networks make up the majority of the extracellular matrix in many organs, such as the skin. The mechanisms which are involved in the maintenance of homeostatic equilibrium of these networks are numerous, involving the regulation of genetic expression, growth factor secretion, signalling pathways,…
The effect of Sr addition on mechanical and bio-corrosion properties of as-cast Mg-3wt.%Zn-0.5wt.%Ca-xwt.%Sr (x = 0.3, 0.6, 0.9) alloys were examined for application as biodegradable implant material. The microstructure, mechanical properties and corrosion resistance of the as-cast Mg-Zn-Ca-Sr alloys were characterize…
Recycling of ethylene-propylene-diene terpolymer (EPDM) scrap was tried by blending with polypropylene (PP). EPDM scrap powder was prepared by shear pulverization process at high temperature, which may lead to selective chain scission induced by difference in the critical elastic coefficient. On the other hand, EPDM s…
The amplitude-frequency electro-optic (EO) modulation by nanocomposite of room-temperature nematic liquid crystal heptylcyanobiphenyl (7CB) and 3 wt.% silica nanoparticles (SiNPs) of size ~7nm, was studied. Thin (25μm) films of SiNPs-7CB soft gel exhibit an extended and flat second-harmonic EO modulation that can b…
Environmental problems from petroleum-based plastic wastes have been rapidly increasing in recent years. The alternative solution is focus on the development of environmental friendly plastic derived from renewable resource. Poly(lactic acid) (PLA) is a biodegradable polymer synthesized from biomass having potential t…
An IP-2 type container is used for the transport of low-level radioactive materials. An IP-2 type metal container was modeled and analyzed for the dropping conditions in normal transport conditions required by NSSC Notice 2014-50, "Regulations on the packaging and transport of radioactive materials." Structural analys…
We synthesize a nanosized lanthanum silicate, La9.33Si6O26, by means of a hydrothermal method, and then investigate the crystal structure by the Rietveld analysis and the maximum-entropy method using a neutron Bragg profile. In addition, we study electrical conduction properties of the sintered pellet with conductivit…
The proposed method will simulate the magnetic component (EE and Toroidal core) in 3D and decrease the needed processing time. The method consists of several simplifications and adjustments to determine the sought parameters (resistance & inductance) in low/high frequency without losing accuracy when compared with the…
Partially Ag-exchanged Na-P1 type zeolites were prepared using an Na-P1 type zeolite and a silver nitrate solution. Emission spectra of the samples prepared at various concentrations of the silver nitrate solution and at various subsequent heat-treatment temperatures were compared. The structure of the Na-P1 type zeol…
Supercritical fluid deposition (SCFD) of SiO2-based films was proposed using TEOS precursor with oxidizing agents, for the purpose of low-temperature film deposition. The film deposition was performed in a batch-type closed chamber filled with supercritical carbon dioxide (CO2) fluid. The SiO2-based films were deposit…
This article presents a study of the sensitivities of different parameters that affect the accuracy of simulating flyer plate impact experiments. Two approaches are explored: the CTH hydrodynamic and the LS-DYNA smoothed particle hydrodynamic (SPH) codes. Simulations using these two methods are compared to experimenta…
The study for a new drugis complex and may last ten years or more. It includesthe preparation of the molecule in a pure form,the experimentation on cell lines, the animal testing, and the three phases of clinical trials on humans. In the case in which in vitro results already point to a possible cytotoxicity, addition…
Amorphous Gex Se90-x Sb10 thin films were prepared by thermal evaporation under vacuum onto glass substrates. Reflectance and transmittance were measured in the wavelength range 190-900nm. The optical properties of the as deposited and UV-irradiated films at different exposure times were reported. The compositional de…
In this study, we successfully synthesized CaAlSiN3:Ce3+ at 1073 K using the ammonothermal method. The synthesis temperature was 900 K lower than that in the conventional solid-state reaction. The product exhibited a broad emission band that was centered at approximately 550 nm by irradiation of 440 nm blue light. Fur…
In recent years, nanoparticles have held great promise for successful drug targeting and controlled drug release. Many nanoparticle applications have been used to maximize the enhanced effective accumulation and intracellular entry. Because of the physicochemical properties of particles determine their therapeutic eff…
In this paper, the phase change characteristics of Sb-Te-Se films were systematically studied by in-situ resistance-temperature measurement, X-ray diffraction (XRD), Raman scattering spectroscopy, X-ray photoelectron spectra (XPS), and Transmission electron microscopy (TEM). For preferred Sb 56 Te 24 Se 20 and Sb 55 T…
Preparation of CaO core-SiO2 shell nanoparticles as a chemical thermal storage through hydration/de-hydration of CaO/Ca(OH)2 was proposed. Firstly, SiO2 was coated on CaCO3 template surface using sol–gel route and then the core–shell particles were heated at 700°C to form CaO@SiO2 nanoparticle by de-carbonization. A t…
A method was developed to fabricate luminescent films at around room temperature based on successive ionic layer adsorption and reaction (SILAR). Nanocrystalline CePO4:Tb3+ films were deposited on bare or surface-modified silica glass substrates through immersion in cation (Ce3+ and Tb3+) and anion (PO43−) solutions s…
The synthesis conditions of a nano-sized magnetite powder using a reverse coprecipitation method were studied in order to control the particle size and the heat generation ability in an AC magnetic field for thermal coagulation therapy. A low temperature reaction and high concentration of the mixed irons as the starti…
