For the development of real-time control systems of integrated urbanwastewater systems (IUWS) fitting a model to measurement data is an importanttask. Generally, model complexity conflicts with computational demand. Theproblem increases when multi-criteria optimization is carried out. Therefore, in thecase of IUWS mod…
SnAg nanoparticles (SnAg NPs) were prepared by wet synthesis. The chemical composition of the SnAg NPs was messured by inductively coupled plasma - mass spectrometry. The prepared fine powder samples were characterized by electron microscopic technique (SEM) and thermal analysis (DSC). The nanoparticles with different…
The TiO2 thin films were successfully coated by spin coating technique using Ti(OH)2 as a precursor. The precursor was prepared by sol-gel synthesis. The TiO2 thin films were dye-sensitized with Lawsone dye extracted from Lawsonia Inermis. The as-synthesized TiO2 thin films were subjected to X-ray Diffraction (XRD), F…
In the present paper, pure nanocrystalline zinc oxide compound was synthesized by chemical co-precipitation method. The composite of Polyaniline with nanosized Zinc Oxide was prepared by In-situ chemical oxidation polymerization method with ammonium per sulphate as an oxidant in aqueous hydrochloric acid under constan…
Special wound care products were developed using Poly vinyl alcohol (PVA) blended with Chitosan. Electrospinning technique was adopted to produce PVA/Chitosan nanomembranes, which were used as wound dressings. PVA/Chitosan wound dressings (PCNWD) have high moisture vapour transmission property and good antimicrobial a…
Nanokomposit PAni/Fe 3 O 4 telah diteliti sebagai material penyerap gelombang mikro. Dalam hal ini, PAni berperan sebagai matriks, sedangkan nanopartikel Fe 3 O 4 berperan sebagai filler. PAni disintesis dengan menggunakan metode polimerisasi oksidasi secara kimia, sedangkan nanokomposit PAni/Fe 3 O 4 disintesis denga…
The effect of the shortening under linear friction welding on the microstructure in the welding zone of two-phase titanium alloys VT6 and VT8M-1 was investigated. It was found that shortening under linear friction welding determines the quality of welded joints. Linear friction welding with shortening 0,4 mm does not…
Magnetic bilayer films with an interface of α-Fe(100) and Nd2Fe14B(001) planes were fabricated in order to evaluate the exchange-coupling constant, which was recently reported to depend on the Miller indices of the interface planes. The epitaxial growth of both α-Fe and Nd2Fe14B layers was confirmed with the epitaxial…
Advanced biocomposite materials from microcrystalline cellulose (MCC) and alginic acid (AA) were produced using 1-butyl-3-methylimidazolium chloride ([C 4 mim]Cl) as the biopolymers’ solvent. The effect of factors such as the mass ratio of cellulose and alginic acid in the materials as well as the soaking agent used f…
The nanoinstability of single-wall carbon nanotubes(SWCNT) under electron beam irradiation is systematically investigated by in-situ transmission electron microscopie observation at room temperature. Under the same irradiation condition, it is found that with the increasre irradiation time(or electron dose), the SWCNT…
Fiber-reinforced polymers (FRP) have been used widely in building, construction and mass transit applications in many parts of the world. Although some efforts towards the harmonization of fire performance standards are taking place (like EN45545 in the European train industry) most countries continue to have their ow…
Radioactive waste produced in Morocco had low and medium activity; the treatment supported to this kind of waste is the cementation, an ensured method with low cost used to confined and stabilized radioactive elements inside the package of cement. For insuring the sustainability of this management of cemented radioact…
Amphiphilic diblock copolymers consisting of linear or hyperbranched polyethylene (PE) and poly[oligo (ethylene glycol) methyl ether methacrylate] (POEGMA) were synthesized via atom transfer radical polymerization (ATRP) initiated by PE macroinitiators (MIs). The MIs contained an end-capping 2-bromoisobutyryl group pe…
ZusammenfassungMagnetic-Particle-Imaging (MPI) ist ein neues tomographisches Verfahren für die medizinische Diagnostik. Es wurde erstmals 2005 in der Zeitschrift Nature von B. Gleich und J. Weizenecker vorgestellt [125]. In MPI wird keine natürliche Konstante des Gewebes gemessen, sondern die örtliche Verteilung eines…
The meshless element-free Galerkin method was generalized and an algorithm was developed for 3D dynamic modeling of deformable bodies in real time. The efficacy of the algorithm was investigated in a 3D linear viscoelastic model of human spleen subjected to a time-varying compressive force exerted by a surgical graspe…
Graphene was obtained by vacuum-assisted thermal expansion of graphite oxide followed by a further thermal annealing.A series of polyacrynitrile(PAN)-based nanofibers with different graphene contents were prepared by electrospinning,using the graphene as the reinforcement.SEM,XRD,FT-IR,TG-DSC and elemental analysis we…
Cold SF6 gas flow field is calculated and analyzed for three kinds of Laval nozzle structures to guide thermal gas flow field simulation in high voltage circuit breakers.The influences of different nozzle length,upstream and downstream pressures are investigated by comparing the variety characteristics of the pressure…
With increasing applications of UHV and EHV silicone rubber composite insulators in China,aging problem and long-term performance evaluation of silicone rubber insulators(SR insulators) become urgent issues to be studied.We discussed dynamic contamination and hydrophobicity changing process in service condition,and pr…
The diffusion of benzene,toluene and ethylbenzene in amorphous polyethylene(PE) membrane was studied in this paper,and their diffusion coefficients were analyzed and calculated by molecular dynamics simulation.The diffusion coefficients were calculated with the clustering method.The calculated results have the same tr…
Triptolide is a diterpenoid isolated from Tripterygium wilfordii which has various functions including immunoregulation,anti-inflammation,antifertility,and anticancer.But its adverse effects are severe,which mainly associated with damages to the digestive,circulatory,urinary,reproductive,and immunologic systems.This r…
