It is interesting that in preparing process of nanosilicon by pulsed laser, the periodic diffraction pattern from plasmonic lattice structure in the Purcell cavity due to interaction between plasmons and photons is observed. This kind of plasmonic lattice structure confined in the cavity may be similar to the Wigner c…
Polymer nanocomposites are the better choice for most of the applications because of its less weight and tailorability to suit different applications. Several nanocomposites have been fabricated with nanoparticles reinforcement and fibre reinforcement. But most of them were made to satisfy few criteria or one or two f…
We discuss transport properties of graphene related to the resonant scattering from impurities and defects. Two dierent models describing defects in the bulk of graphene or at the graphene surface are used for the calculation of self energy of electrons scattered from short-range impurities or defects. The results of…
In this article we present analytical derivation of the Fuss relations for n = 11 (hendecagon) and n = 12 (dodecagon). We base our derivation on the Poncelet closure theorem for bicentric polygons, which states that if a bicentric n-gon exists on two circles then every point on the outer circle is the vertex of same b…
Thermal conductances between Cu and graphene covered carbon nanotubes (gCNTs) are calculated by molecular dynamics simulations. The results show that the thermal conductance is about ten times larger than that of Cu-CNT interface. The enhanced thermal conductance is due to the larger contact area introduced by the gra…
Photodynamic therapy (PDT), because of its good targeting, minimal invasion, and safety, is becoming a very active area in cancer prevention and treatment, in which the photosensitizers have proved to be the core element for PDT. We developed a new HPLC method for analyzing porphyrin photosensitizers using Shiseido Ca…
OBJECTIVE: To investigate whether endoscopic saphenous vein harvesting (EVH )reduces leg wound morbidity and improves rehabilitation of lower extremity as compared to open vein harvesting (OVH) in patients with coronary artery disease. METHODS: The clinical data of 333 patients who underwent isolated coronary artery b…
Rare-earth (RE) doped photonic glasses exhibit potential applications in the area of optical communication, laser lidar, remote sensing, infrared detection, and biomedical. Up to now, the widely used silica based photonic glasses encounted intrinsic limitations such as lower rare-earth doping concentration, narrower e…

Abstract Nucleation is much more important for clay minerals than for other authigenic cements as clay crystals are very small, so that a very large number of clay crystals must be nucleated. The role of this difficult kinetic step in the diagenesis of sandstones has not been considered adequately as a ratedetermining…
Commercial natural dyes are quite costly as manufacturers are to follow multi-step extraction and purification procedures for standardisation purposes. Upon cost comparison, they lose in the market to synthetic dyes. However, in the handicraft sector, reproducibility may be of lesser importance against cost. In the pr…
This paper investigates correlations of Partial Discharge (PD) measurements of associated statistical parameters from phase-charge-number Φ-q-n plots from IEC60270 PD measurements and High Frequency Current Transformer (HFCT) Φ-peak-n plot PD measurements. These are also compared with Electromagnetic Interference (EMI…
Nanouids are suspensions of nanometrical size particles in a liquid base, which is usually water, oil or ethylene glycol. The potential practical use of nanouids caused in recent years a considerable intensication of research into their properties. The most widely studied of physical properties include the uid rheolog…
Investigation of the microstructure and mechanical properties of heavy plates strength grade S355 in thickness range 5–150 mm from low carbon structural steels, microalloyed with vanadium and regulated nitrogen content was made. Main parameters of the microstructure and mechanical properties after hot rolling, normali…
A finely dispersed powder of composition Mg(Fe 0.8 Ga 0.2 ) 2 O 4 was prepared by glycine-nitrate method. The use of glycine as a reducing agent allows preparation of the product without carbon-containing admixtures with unimodal particle size distribution and lower crystallization temperature (as compared with nitrat…
In this work, the effect of particle size on dielectric, electrical and thermal properties of highly charged (50 wt.%) h-BN micro and nano-filled Ultra High Molecular Weight Polyethylene (UHMWPE) samples was investigated. The dielectric properties of the composite samples were characterized using dielectric spectrosco…
Processing and characterisation of depleted UO2-based Simulated Spent Nuclear Fuel (SIMFuel), which aims to replicate both chemistry and microstructure of Spent Nuclear Fuel (SNF) discharged from a UK Advanced Gas-cooled Reactor (AGR) after a prolonged cooling time is described in this thesis. Thirteen fission product…
The effect replacing Fe atoms with Sc atoms has on the spatial spin-modulated structure and electrical and magnetic hyperfine interactions of 57 Fe nuclei in BiFeO 3 multiferroic is studied by means of Mössbauer spectroscopy. The temperature dependences of the parameter of anharmonicity and hyperfine parameters of the…

Extensive experimental work in the area of polymer nanocomposites has been done over the past two decades to explore their potential. In this study, a range of related polymer nanocomposite materials was prepared using a solvent blending method, using dichloromethane (DCM), toluene (TOL) and chlorobenzene (CB) to diss…
