The aim of this study was to design a functional bio-engineered material to be used as scaffold for autologous mesenchymal stem cells in ligament tissue engineering. Polyelectrolyte modified HEMA hydrogel (HEMA-co-METAC), applied as coating on silk fibroin fibres, has been formulated in order to take advantage of the…
Nanocrystalline zinc oxide (nc-ZnO) thin films with c-axis orientation were deposited on Si (100) substrates at a temperature lower than 100 °C by plasma assisted pulsed laser deposition from metallic zinc. Oxygen plasma generated by electron cyclotron resonance (ECR) microwave discharge was used as a reactive and ene…
The characteristics of the phase retardations and the invariability against the incident angles are investigated when light enters the rectangular holes with different sizes perforated on metallic film. A kind of metallic structure with a great potential in imaging is brought forward. The finite difference time domain…
Optical properties of silicon-rich–silicon oxide (SRSO) films have been investigated by emission and absorption spectroscopies in the broad spectral range. The impact of the different hydrogen partial pressure of the sputtering method on the absorption properties of SRSO films has been described and commented on. For…
This CFD study is to simulate a coolant (gas) flow and heat transfer in a PBR core during a normal operation. This study used a pebble array with direct area contacts among the pebbles which is one of the pebbles arrangements for a detailed simulation of PBR core CFD studies. A CFD model is developed to more adequatel…
A primary data survey was conducted to evaluate the market potential of lignosulfonate as a raw material for plasticizers in the concrete industries of Austria and southern Germany (Bavaria). The results showed significant differences between the countries. Since 2002 lignosulfonate-based products have been massively…
Summary Maintaining the quality and freshness of fruit and vegetables during transportation and storage is an important role for most postharvest industries. One way to control freshness is by carefully monitoring and regulating exposure to ethylene. By limiting exposure to ethylene the natural aging process of fresh…
We have managed to build up a computer controlled measurement system applying National Instruments Data Acquisiton card and National Insturments LabVIEW software package. First, in a previous study, the specimen under test has been simulated by the Jiles-Atherton model of hysteresis, but simulated measurements have be…
Microgels of chemically cross-linked poly(allylamine hydrochloride) (PAH) and dextran (named PAH-D) encapsulated with magnetic Fe3O4 and luminescent CdTe nanoparticles were successfully fabricated. The superparamagnetic Fe3O4nanoparticles were firstly incorporated into PAH-D microgels by in situ synthesis of Fe3O4nano…
Six bidentate building blocks have been used to form a tripodal ligand with a flexible C3 symmetric spacer to direct the assembly of large octametallic clusters covalently linked to form a 1-D highly luminescent terbium tube-like polymer.
The mechanical properties and processing performances of conventional magnesium alloys still could not meet the need of important application fields due to some demerits, such as poor formability, low creep resistance and unsatisfactory strength at elevated temperature. Recent investigations have shown that additions…
In this letter, we address the design of thin planar retrodirective reflectors via transformation optics. Exploiting form-invariant transformations of Maxwell's equations, we derive the constitutive properties of an anisotropic and spatially inhomogeneous transformation-medium coating which, laid on a flat metallic su…
Electron paramagnetic resonance (EPR) has been used to study the properties of trapped electrons or holes in XLPE and in 12.5% vinylsilane-treated SiO2nano-particles in XLPE specimens. Both electrically unstressed and electrically stressed (up to 25 kV/mm) specimens were used. The EPR spectra of both materials indicat…
Degree of poly (lactic acid) (PlA) foil degradation by the filamentous fungi i.e. Aspergillus ustus, A. sydowii, A. fumigatus, Paecilomyces lilicanus and Penicillium verrucosum has been investigated. A degradation process has been conducted in dynamic conditions at 30°C for 10 days in a medium containing 0.1% of foil…
Pulsed thermoelectric cooling is an attractive approach for the site specific thermal management of infrared sensors and other low-heat flux devices. Intense Joule heating caused by electrical interface resistance, however, can severely degrade pulsed cooling performance. Numerical simulations are used to quantify the…
Formation of the first binary stacks of an intact organocopper aggregate with the arenes naphthalene and 2,2'-bithiophene is reported; crystallographic data suggest that the supramolecular assembly process is supported by Cu-pi, Cu-S, and perfluoroarene-arene pi-interactions.
We have investigated the carbon mono-vacancy in Ta4AlC3 by first-principles calculations. We identify the 2a sites as the probable carbon vacancy sites in Ta4AlC3 based on the energetics of vacancy formation. It was found that introducing carbon vacancies decreased the phase stability of Ta4AlC3. There are no signific…
Kinetic data for structural relaxation in silver iodomolybdates at the glass transition temperature (Tg) are obtained by high-pressure differential scanning calorimetry (HP-DSC) and are compared with activation energies (EA) and volumes (VA) obtained earlier from conductivities below Tg. The results are fitted to an e…
A novel approach for the creation of photopatternable fluorescent polyethylene-based liquid crystal composites was developed. Stretched porous polyethylene (SPPE) films were used as the polymer matrices. A liquid crystalline (LC) photopolymerizable mixture containing nematogenic dimethacrylate, cholesterol-containing…
Vegetable oil-based and potentially biodegradable polyesters were prepared from 9-hydroxynonanoic acid methyl ester. This paper describes ozonolysis of vegetable oils and the method for preparation of useful monomers and in particular 9-hydroxynonanoic acid methyl ester. Ozonolysis of soybean oil and castor oil in met…
