The application of fiber reinforced composites for sports instruments is introduced. The advantage of fiber reinforced composites, materials selection, products varieties, examples and status of application for sports instruments are discussed.
Spasers have been theoretically predicted and experimentally observed and promise to deliver new exciting nanophotonic and biomedical applications. Here we theoretically investigate ultrafast dynamical properties of spasers with external plasmonic feedback. We consider a spaser both as a nanoscale source and detector…
This is the first study on the co-pyrolysis of spent substrate of Pleurotus ostreatus and coal tar pitch, and the activated carbon prepared from the pyrolytic char. Thermogravimetry (TG) analysis was carried out taking spent substrate, coal tar pitch and spent substrate-coal tar pitch mixture. The activation energies…
We studied electrical conductivity and dielectric relaxation in polyvinyl alcohol/ammonium chloride and polyvinyl alcohol/ammonium acetate composite films. Infrared absorbance showed the presence of H-bonding interaction between the salt and the polymer. X-ray diffraction showed the reduction of the grain size of orde…
α-tricalcium phosphate (α-TCP), which shows higher solubility than β-TCP, is bioabsorbable and receives special attention for its ability of turning into hydroxyapatite (HAp) in a physiological condition. Problems occasionally occur as α-TCP porous body is too brittle to be handled. Compressive strengths of β-TCP and…
The interatomic interaction and chemical state of elements in amorphous multilayered (Co 45 Fe 45 Zr 10 / a -Si) 40 and (Co 45 Fe 45 Zr 10 /SiO 2 ) 32 nanostructures with different interlayers have been investigated by X-ray photoelectron spectroscopy using synchrotron radiation. The results of X-ray photoelectron spe…
Benzo[de]isoquino[1,8-gh]quinolines were prepared by the reaction between 1,5-diethynyl-9,10-anthraquinones and urea in DMF. Light-induced electron transfer from regioregular poly(3-hexylthiophene) to the synthesized molecules was detected by an EPR spectroscopy technique.
ZnO nanorods with controlled-surface density have been successfully obtained by simply varying the concentration of the growth solution. It was found that the variation in the growth solution concentration may vary the surface density of the ZnO nanorods arrays grown on the surface. The lowest concentration produces t…
The most important parameters of a synchronous reluctance machine (SynRM) from a design optimization and control point of view are both the ratio and the difference between the inductances in the d and q axes, since they define the machine's characteristic such as torque and power factor. The direct-axis and quadratur…
A novel magnetostrictive-ring type torque sensor has been developed which used a new detection scheme for detecting the differential magnetic field and signal conditioning circuitry with the temperature drift compensation. Torque of a shaft was measured by detecting the leakage magnetic field emanating from the magnet…
Composite Fe nanoparticles (CINPs) were synthesized by surface modification of Fe nanoparticles with silicon alkyl ethylenediamine triacetic acid, and the silicone oil-based composite Fe nanofluids (CINPs nanofluids) were prepared with the as-synthesized CINPs and silicone oil. The surface molecular structure, magneti…
The thermodynamic solubility product for baryte, determined at standard conditions, from data in commonly used compilations, was compared with published experimental solubility products for baryte and with the solubility products from databases used by the PHREEQC geochemical speciation code and MultiScale, which is o…
This study focused on developing a surface cleaning treatment for one type of commercially available plasticized poly(vinyl chloride). The effects of cleaning solutions on samples of plasticized poly(vinyl chloride) were examined by several methods. The sample surface, prior to and after artificial photo-aging, was cl…
The paper proposes an ozone generation generated by double dielectric barrier discharge chamber which is operated at atmospheric pressure discharge and supplied by high frequency power converter. The air fed or oxygen is bombarded inside chamber that is constructed by a planar type chamber using double aluminum mesh o…
Graphene oxide (GO) is a hotspot, especially in the field of biomedical. However, the clinical application of GO is still faces a lot of challenges. In order to improve the solubility and biocompatibility of GO, polyethylene glycol (PEG) was grafted on the surface of graphene oxide by amide reaction. PEGylated graphen…
Microwave-assisted magnetic recording (MAMR) is one of the promising techniques for future high recording density hard disk drives. In this paper, we estimate the effective field gradient in MAMR using the relation between recorded transition length πa and field gradient by dynamic write process simulation. The effect…
We present optical studies of individual and few GaSb quantum rings embedded in a GaAs matrix. Contrary to expectation for type-II confinement, we measure rich spectra containing sharp lines. These lines originate from excitonic recombination and are observed to have resolution-limited full-width at half maximum of 20…
Mesenchymal stem cells (MSC) are increasingly being proposed as a therapeutic option for treatment of a variety of different diseases in human and veterinary medicine. Stem cells have been isolated from feline bone marrow, however, very few data exist about the morphology of these cells and no data were found about th…
The technical and economic growth of the twentieth century was marked by evolution of electronic devices and gadgets. The day-to-day lifestyle has been significantly affected by the advancement in communication systems, information systems and consumer electronics. The lifeline of progress has been the invention of th…
Mesenchymal stem cell (MSC) transplantation has attracted much attention in myocardial infarction therapy. One of the limitations is the poor survival of grafted cells in the ischemic microenvironment. Small interfering RNA-mediated prolyl hydroxylase domain protein 2 (PHD2) silencing in MSCs holds tremendous potentia…
