One approach to the tissue engineering of vascular structures is to develop in vitro conditions in order ultimately to fabricate functional vascular tissues before final implantation. In our experiment, we aimed to develop a new combined cell seeding and perfusion system that provides sterile conditions during cell se…
Abstract Foams containing poly(lactic acid) (PLA) have been prepared from the corresponding macromonomers using high internal phase emulsions (HIPEs) as templates to create the porous structure. The resulting PolyHIPE foams have been investigated by scanning electron microscopy and the influence of diluent type, eithe…
α-Al 2 O 3 nanowires and nanobelts have been successfully synthesized from Al pieces and SiO 2 nanoparticles at 1200 °C and 1150 °C, respectively, in a flowing Ar atmosphere. The α-Al 2 O 3 nanowires are uniform with diameters of 20−70 nm and lengths of 15−25 μm, and the nanobelts are several to tens of micrometers lo…
Nacre organic matrix has been conventionally classified as both 'water-soluble' and 'water-insoluble', based on its solubility in aqueous solutions after decalcification with acid or EDTA. Some characteristics (aspartic acid-rich, silk-fibroin-like content) were specifically attributed to either one or the other. The…
Direct band gap copper indium chalcogenides are of great technological importance in part because of their high photovoltaic conversion efficiency. Covalent superlattices constructed from copper indium chalcogenide clusters are of particular interest because they may combine open framework architecture with semiconduc…
The synthesis and electrochemical polymerization of 3,3-diethyl-3,4-dihydro-2H-thieno-[3,4-b][1,4]dioxepine (ProDOT-Et2) was performed resulting in a stable electrochromic polymer capable of switching between an absorbing blue neutral state and a highly transmissive sky-blue oxidized state in sub-second time frames. H…
The exact physical adsorption amounts of supercritical hydrogen on the single-wall carbon nanohorn (SWNH) assemblies were determined at 77, 196, and 303 K. There are two physical adsorption sites of interstitial and internal spaces on SWNH assemblies. The interaction potential depths of interstitial and internal space…
Well‐crystallized cerium(IV) oxide (CeO 2 ) powders with nanosizes without agglomeration have been synthesized by a hydrothermal method in an acidic medium by using cerium hydroxide gel as a precursor. The relationship between the grain size, the morphology of the CeO 2 crystallites, and the reaction conditions such a…
X-ray diffraction, Raman, and X-ray photoelectron spectroscopy were utilized to characterize CeO 2 /SiO 2 supports and V 2 O 5 /CeO 2 /SiO 2 catalysts calcined at different temperatures from 773 to 1073 K. The CeO 2 /SiO 2 support was obtained by an aqueous deposition precipitation method, and vanadium oxide was appli…
In artificial joints, the bone part is usually substituted by a metallic component with high corrosion and strength resistance while the articular cartilage is replaced by a polymer. Use of thin layer of a compliant material acting as a bearing surface in human replacement joints has recently generated considerable in…
Carbon fibres and glass fibres are reinforcements for advanced composites and the fiber strength is the most influential factor on the strength of the composites. They are essentially brittle and fail with very little reduction in cross section. Composites made with these fibres are characterized by a high strength/de…
N2 and CO2 gases adsorption by tetramethylammonium(TMA)-montmorillonites and hexadecylpyridinium(HDP)-montmorillonites was carried out using volumetric equipment at 25 °C and 0.1 MPa. The addition of organic compounds to montmorillonites was 1 and 4 times the cation exchange capacity (CEC) of the montmorillonites and…
Article Evaluation of Adherence and Performance of Epoxyphenolic Coatings on Electrolytic Tinplates was published on October 1, 2002 in the journal Science and Engineering of Composite Materials (volume 10, issue 5).
P+-type emitters were optimized keeping the base parameters constant. Updated internal parameters were considered. The surface recombination velocity was considered variable with the surface doping level. Passivated homogeneous emitters were found to have low emitter recombination density and high collection efficienc…
In the case of some highly viscous fluids, or thick pastes (such as those exhibiting high yield stress and/or high plastic viscosity), neither rotational nor tube type viscometers are suitable for rheological characterisation. Due to their capacity for generating and maintaining high torque or high rates of rotation,…
Article Thermal Expansion and Oxidation of 3D C/SiC Composites with Different Coatings from Room Temperature to 1400°C was published on October 1, 2002 in the journal Science and Engineering of Composite Materials (volume 10, issue 5).
The 2.25Cr¾1.0Mo steel is widely used in petroleum refining units, for example, in pressure vessels, working under severe operational conditions. Due to the high temperatures of some processes, many phenomena such as precipitation of carbides and their coarsening occur during service, resulting in changes of material…
PolyFlow, a software package based on the finite element method was employed to simulate the extrudate swell for polybutadiene of various molecular weight (Mw) and molecular weight distribution (MWD). We calculated the relaxation spectra for the different samples and then inserted the spectra into a standard K-BKZ con…
