The aim of the present study was to apply experimental design methodology in the development and optimization of sirolimus liposomes employing a modified ethanol injection method. Dipalmitoylphosphatidylcholine (DPPC) and cholesterol (Chol) as well as dioleoylphosphoethanolamine (DOPE) were utilized in the preparation…
Summary: A solvent-free environmentally benign synthesis of oleylamine capped silver nanoparticles is presented. Upon heating 10 equivalents of oleylamine and silver nitrate at 165°C for 30 min followed by a precipitation step using ethanol as the precipitant particles characterized by an Zaverage diameter of 63 nm we…
In this paper, the problem of the summation of harmonic currents of induction motor variable-speed drives (IM VSDs) is analyzed based on computer simulations and field measurements. As a first step, the influence of different parameters on the phase angles of current harmonics of different orders is analyzed using com…
InGaN/GaN multiple quantum well (MQW) structures with different GaN barrier growth temperatures have been grown by metallorganic chemical vapor deposition (MOCVD) and investigated. Double peak InGaN emission was observed and correlated to the barrier growth temperature. It was deduced that the extra emission peak orig…
Summary The effect of laser on wound healing has been approved but the role of Low Red (LR) and Infrared Low Level Laser (ILLL) on unmeshed full-thickness free skin autograft (UFFSA) is not clear yet. The aim of the present experimental study is to determine the effectiveness of LR and ILLL in UFFSA in rabbits. The st…
A series of solid solutions of 1-x(Bi0.85La0.15)FeO3–xPbTiO3 for x = 0.35, 0.4, 0.415, 0.43, 0.45, 0.47)(BLFPT) are prepared by the mixed oxide method. The X-ray diffraction analysis shows that BLF-PT has a single perovskite phase with mixed tetragonal and rhombohedral phases in x = 0.415. The dielectric constant and…
The employment of glycerol phosphate as initiator for the synthesis of polyether polyols is explored in order to open the possibility of preparing a new range of products with enhanced flame retardant properties. For this purpose, glycerol phosphate disodium salt was employed as initiator, caesium hydroxide was select…
PROTEUS is a zero power reactor at the Paul Scherrer Institute which has been employed during the 1970’s to study experimentally the physics of the gas-cooled fast reactor. Reaction rate distributions, flux spectrum and reactivity effects have been measured in several configurations featuring PuO2/UO2 fuel, absorbers,…
Abstract: The degree of effect of cold plastic deformation on change of the controlled magnetic parameter of structural steels is investigated. It is shown that with the increase of deformation ratio, stray magnetic field strength in zones of control changes the sign from the positive to negative and at deformation ra…
Some organic compounds were studied as inhibitors of bismuth dissolution in passive state and under depassivation conditions in 0.1 M sodium chloride solution.The relationship between the effects of the organic additive and the Cl -ion was estimated.Information about the influence of additives on the rate-limiting ste…
Functional multilayer films that contain ion-recognition agents, including 1-aza-18-crown-6 (A18C6), benzo-18-crown-6 (B18C6), B15C5-An-A18C6, are developed. The ion-selective behaviors of these multilayer films were characterized by means of electrochemical or fluorescent methods. The functional multilayer films may…
Mesoporous silica nanoparticles (MSNs) have been employed as a versatile solid support for constructing a variety of hybrid materials for controlled drug delivery. Controlled release systems that integrate external stimuli with nanocarriers have attracted much attention for sensors and drug delivery applications. Meso…
A column experiment was conducted to study the release behavior of technetium, uranium, and selenium initially sequestered in reducing grout similar in composition to Savannah River Site (SRS) saltstone, a cementitious waste form made by mixing salt solution from SRS liquid waste storage tanks with a dry mix containin…
The correlations and nature of the internal, thermo-electro-mechanical fields of ferroelectrics were investigated. The thermodynamic equation and the equation of the properties of matter which are satisfied by the internal, electric and mechanical fields were given. For the reduced, thermo-electric coupling case, the…
Time- and angle-resolved photoemission spectroscopy with a high–harmonic- generation source is used to classify the potential excitonic insulator 1T-TiSe2 and the reference Peierls-Mott insulator 1T-TaS2 on the basis of the melting times of “spectroscopic order parameters”.
The physical immobilization of antibodies via spot-drying on polymer brush, poly(oligo(ethylene glycol) methacrylate) (POEGMA), was investigated by employing immunoglobulin G (IgG). Fluorescence measurements across a wide range of brush thicknesses from ∼6 to 102 nm interestingly revealed that the protein loading capa…
Cable shovel is a primary excavation unit in many surface mines around the world. The capacities of the shovels have seen an ever increasing trend to achieve the economies of large scale operation. The modern day shovels have 100+ tons per pass production capacities. The dynamic force of 100+ ton material combined wit…
BACKGROUND: Barrett's esophagus (BE) affects up to 12 million Americans and confers an increased risk for development of esophageal adenocarcinoma (EAC). EAC is often fatal unless detected early. Given the high prevalence, high cost of surveillance and relatively low risk of most affected individuals, identification o…
The multiple applications of gold nanorods (AuNRs) are most effective if the longitudinal surface plasmon resonance (SPR) can be simultaneously excited in all the involved AuNRs. This can be achieved in well aligned ensembles of AuNRs, obtained by stretching AuNR-polymer composite films, as a possible method. One of t…
Nanoscale iron (Fe)–silica (SiO2) core–shell agglomerates were conveniently obtained via gas-phase hybridization of freshly produced Fe with SiO2 synthesized in an aqueous medium containing polyethyleneimine. Synthesized Fe–SiO2 agglomerates were employed as nanocarriers for gene transfection and magnetic cell pattern…
