Breast cancer is the most common type of cancer in women worldwide and it is the second cause of cancer death after lung cancer. There have been many efforts in producing various pharmaceuticals for breast cancer treatment and among them Nanopharmaceutical Sciences have been extremely of high importance. All the drugs…
High-pressure hydrogen gas seal is one of key technologies for realization of hydrogen energy system. It is important to understand the durability of high-pressure gas seal. Ethylene-propylene rubber (EPDM) and acrylonitrile-butadiene rubber (NBR) composites filled with carbon black, silica, and unfilled composites we…
Composites of modified halloysite and polyamide 6 (PA 6) have been synthesized by the thermoplastic processing method and their mechanical and thermal properties as well as structure studied. The layered mineral samples modified with ultrasound and then with gelatin (codenamed HUŻ) were found to have a positive influe…
Growth of ZnO nano and microstructures were carried out by low temperature hydrothermal method on glass and silicon substrates without seed layer. Crystallographic orientation and morphology of the samples were studied by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The transmittance measurements we…
on zirconium dioxide under hydrothermal conditions is the chemical prehistory of the starting materials. The possibility of varying the synthetic parameters to obtain a zirconia-based material with high porosity and specic surface area was shown.
This paper present the study of aqueous CO foam prepared 2 by a mixtures hydrophilic silica nanoparticles and non-ionic Triton X100, TX100, surfactant. The synergistic effects of the mixture on stabilizing the CO2 foam were inferred into few key parameters namely; particles and surfactant concentration, adsorption of…
Gelatin from the skin of Thai panga fish (Pangasius bocourti Sauvage) was pretreated with a solution of 0.8 M sodium chloride and 0.1 M sodium hydroxide and extracted by acetic acid solution pH 4.55 at 55°C for 1 h. Physical properties of the obtained fish gelatin and the commercial bovine bone gelatin were compared.…
Perovskites belong to one of the largest oxide families. The interesting physical properties and important applications have been widely investigated in this system since the last century. Among the large perovskite family, one of the most important groups is the ferroelectric oxide, which possesses extremely high val…
In this paper, we present the effect of different catalysts (Mn, Au and Sn) on the room temperature photoluminescence and Raman spectra of VLS grown ZnS nanostructures. The catalysts found to self-dope the ZnS nanostructures during its growth were confirmed by XRD and XPS results. The extent of self-doping, which depe…
The main aim of this work is to develop a one-step method for the characterization of mixtures of single- and multi-walled carbon nanotubes using a simple and inexpensive tool, a portable Raman spectrometer. In order to overcome the problem of heat dissipation in solid samples, the suitability of three surfactants-SDS…
The improvement of analytical accuracy and S/N (signal to noise ratio) based on conventional homogeneous fluorometry was always limited because of high background noise from complicated sample ingredients, buffer solution and lysates. Herein, a self-assembled Mn-doped ZnSe quantum dot–methyl viologen nanohybrid as an…
The need for biocompatible, low impedance abio-to-bio interfaces suitable for implantable bioactive devices has led us to develop electroconductive hydrogels. Conductive electroactive polymers (CEPs) are one dimensional organic semiconductors synthesized from aromatic monomers into extended pi-conjugated polymers. The…
The application of a mixed ionic and electronic conductor, doped CeO2, as a dense anode was investigated in this study. The mixed electronic and oxide ionic conductivity in CeO2 was significantly improved through the double doping of Mn and Fe. Although the solid solubility limit of Mn was approximately 20 mol%, no im…
The wet chemical etching of InP and its native oxide has been studied in HCl and H 2 SO 4 solution to create oxide-free surfaces.The (100) InP surface is not etched in ≤2 M HCl and ≤6 M H 2 SO 4 .As the v etch <0.1 nm/min for these concentrations, the native oxide after OFOD treatment can be effectively removed withou…
Metal–organic gels (MOGs) are evolving as a new class of stimuli-responsive materials. A redox-active MOG comprised of a ferric ion and benzene tricarboxylic acid ligand was prepared and characterized. In situ incorporation (without the use of any extraneous oxidant) of conducting polypyrrole and polythiophene moietie…
This study presents the effect of carbon to nitrogen ratio (C/N) (mol/mol) on the cell growth and poly(3-hydroxybutyrate-co-3-hydroxyvalerate) accumulation by Comamonas sp. EB172 in 2 L fermenters using volatile fatty acids (VFA) as the carbon source. This VFA was supplemented with ammonium sulphate and yeast extract…
In this paper, high density polyethylene (HDPE)/wood flour (WF) composite foams were prepared by using an intermeshing co-rotating twin screw extruder followed by an injection molding. Experimental design based on Taguchi method was applied to investigate the effects of "concentrations and types of chemical foaming ag…
High quality graphene is synthesized by pyrolysis of poly (acrylic acid) sodium salt, a novel catalyst-free cost-effective process. A strong Raman signature at 2698 cm−1 and a small defect (D) band (D/G ratio) confirm the high quality of the synthesized material. Analysis of the Raman parameters implies that it is a 1…
Crystallization following Ostwald's step rule is given theoretical consideration on the basis of the classical nucleation and growth theory. Conditions for homogeneous 3D nucleation of the thermodynamically metastable crystal, for that of the stable crystal, and for co-precipitation of them are derived from comparison…
The isothermally crystallized poly(L-lactide) (PLLA) samples were obtained at 135 °C under pressures (Pc) ranging from 1 bar to 2.5 kbar. The crystalline structures, the structure transition, and thermal properties of the prepared samples were investigated by wide-angle X-ray diffraction (WAXD), real time synchrotron…
