An ideal scaffold should mimic the morphology of the natural extracellular matrix and have good mechanical properties and biologically functional. So, the key point of fabricating of scaffolds is to realize the composition of scaffolds by materials having different physical and biological properties and control porous…
Abstract Polymer blends of biosourced polyamide (Rilsan XD) and thermoplastic starch grafted polypropylene (LAB4270) were processed by means of a co-rotating twin-screw extruder, using a solid epoxy resin (D.E.R. 664UE) as a compatibilizer. Morphologies as well as rheological, thermal and mechanical properties of the…
Homodyne detection is a detection technique that significantly amplifies optical signals. It is useful for the readout of multilayer optical discs, where the signal level is quite low. The improvement of optical disc readout signal quality by homodyne detection has been demonstrated experimentally. However, homodyne d…
Diffusion-induced stresses in hollow cylinders were investigated. Both diffusion processes of constant surface concentration source from outer into inner surfaces (case A) and reverse case (case B) were studied. We derived the mathematical model of transport property and calculated the radial stress, tangential stress…
We synthesized vertically-aligned multi-walled carbon nanotubes with an inner diameter of 1.6-7.5 nm and stack height of 80-28600 microm by chemical vapor deposition. The effects of synthesis conditions such as substrate position in the tube furnace, maximum temperature, temperature increasing rate and synthesis durat…
Abstract The structures of [Fe III (tacud)Cl 3 ] ( 1 ) and [Fe III (tacn)Cl 3 ] ( 2 ) (tacud = 1, 4, 8‐triazacycloundecane, tacn = 1, 4, 7‐triazacyclononane) are reported. Both compounds crystallize in the orthorhombic space group Pnma with a = 12.5570(9), b = 12.0028(9), c = 8.2577(6) Å, V = 1244.59(16) Å 3 , and Z =…
Patterned sapphire with frustum of a cone shape is designed to grow ZnO nanoflower arrays in this paper. The ZnO nanostructures are grown by two-step approach, including the synthesis of homo-seed layer and the growth of ZnO nanostructures in aqueous solutions at low temperature. The as-prepared samples were character…
In this work , double layer and three antireflection coating were designed and simulated , optical reflection values were deduced with a matrix formulation via a personal computer using matlab program, six materials has been selected to investigated of the reflection as function of wavelength in visible region and nea…
In this paper, nanocomposites are synthesised with Tunisian natural clay which has the advantage of being inexpensive. In fact, it is simply a mixture of several sorts of clays (kaolinite, dolomite, calcite, illite, and quartz). This clay has been cleaned, purified, dried, and steered with polyacrylate resin which is…
Abstract A series of the samples La 1− x (Sr 1− y Na y ) x MnO 3 ( y =0.0, 0.2, 0.4, 0.6, 0.8, 1.0) were prepared by the solid‐state reaction method. Magnetoresistance enhancement and temperature stability of magnetoresistance in the system La 1− x (Sr 1− y Na y ) x MnO 3 with unchanged Mn 3+ /Mn 4+ ratio through the…
In this paper, the basalt fiber/polylactic acid composites were prepared by laying-up hot-pressing process, using PLA sheet as the matrix material and basalt fiber fabrics as the reinforced material, besides, the mechanical properties were studied and the parameters of hot-pressing were optimized. PLA mass fraction, h…
In dry foam, we investigate the link between coarsening rate and bubble distribution. Revisiting Mullins' predictions (Mullins W. W. , J. Appl. Phys. , 59 (1986) 1341), we predict, without any phenomenological assumption, that the volume distribution behaves as v (2− D )/ D (where D is the dimension of space) in the l…
Polyelectrolyte based capsules are recently proposed as drug carriers showing the potentiality to overcome the shortcomings associated to conventional drug formul. Capsule properties such as composition, mechanical stability, morphology and permeability can be engineered at the nanometer scale depending on the specifi…
The influence of calcined temperature and sintered technology on the properties of 0.85 （ Na0.5Bi0.5 ） TiO3-0.144(K0.5Bi0.5)TiO3-0.006BaTiO3(NBT-KBT-BT) lead-free piezoelectric ceramics was investigated by conventional solid state method, and the relationship between calcined temperature, sintered technology and prope…
Diatom species distributions on remote islands are influenced by both habitat quality and location. In this study diatom distributions and water quality were explored in the Falkland Islands archipelago with reference to island floras elsewhere, using 28 freshwater sites (small ponds, shallow lowland lakes, upland tar…
The kinetics of epoxidation of vegetable oils by traditional route (formic acid) or novel routes (peroxophosphatotungstate, methyltrioxorhenium) with hydrogen peroxide (H2O2, 30 wt. %) were investigated. The mathematical models describing the kinetics of epoxidation were developed. Using a linear fit method, kinetic p…
In this paper, unit cells using coplanar waveguide transmission line with composite right and left-handed structure are proposed. The characteristics of the unit cells are analyzed in order to design low-pass filter and high-pass filter in small sizes. By changing the sizes of these unit cells, the parameters of right…
Three-parameter statistical method of the calculation of Qn distribution in silicate melts and glasses has been developed. The method allows determining the concentrations of silicate structural units in wide compositions range at different temperatures when only the limited experimental data are available. The method…
Present ITER diagnostics are designed to provide machine protection, basic and advanced control, fusion performance evaluation, and an extensive measurement capability for furthering plasma physics understanding. However, in the longer term beyond ITER, diagnostic components and associated materials must survive exten…
Los Alamos National Laboratory has completed the conceptual design of the Materials Test Station (MTS), an accelerator-driven neutron source for irradiating nuclear fuel and materials in a fast neutron spectrum. In many respects, the irradiation conditions in the MTS are quite similar to those experienced by the first…
