Gd doped iron-oxide nanoparticles were developed for use in tumour therapy via magnetic fluid hyperthermia (MFH). The effect of the Gd3+ dopant on the particle size and magnetic properties was investigated. The final particle composition varied from Gd0.01Fe2.99O4 to Gd0.04Fe2.96O4 as determined by Inductively coupled…
Abstract In theory and modeling of plasma‐wall interactions, very different spatial and temporal scales need to be resolved. Hierarchy of material models (e.g. macroscopic transport, Kinetic Monte Carlo, Molecular Dynamics, and quantum models) used in fusion applications is reviewed and a way of their integration is h…
Identification of the number of graphene layers using an optical microscope images taken at various magnifications is investigated from the viewpoint of simple wide-area inspection. For graphene on 300-nm-thick SiO2, combination of red and green color contrast gives more accurate contrast value and provides better con…
We present full area laser doped boron emitter n-type silicon solar cells using sputtered boron as dopant source. Quasi-steady-state photo conductance decay measurements show a low emitter saturation current density J0eand an open circuit voltage limit of Voc,lim702 mV for a 128 Ω/sq emitter proving the high quality o…
Experimental tests were carried out to determine if there are any noticeable differences in the way premium and standard efficiency motors operate under abnormal voltage conditions such as over voltage under voltage and voltage unbalance. The results for four motors are compared in terms of efficiency and overcurrent…
We have extended our previous work on trioctylphosphine sulfide (TOP:S) to further elucidate the mechanisms of this chemical passivation for small GaAs solar cells. Photoluminescence (PL) measurements indicate monolayers of TOP:S on GaAs significantly increases the electronic quality of both n- and p-doped wafers. TOP…
This paper studies minimization of cogging torque in fractional-slot winding axial flux PM machines without skewing rotor magnets or displacing stator slots. Fractional winding has small cogging torque which is highlight for applications such as wind turbines. Cogging torque is caused by interaction between rotor magn…
In this letter we establish a link between this approach and the classical density functional theory for inhomogeneous fluids.
Decoctions of the aerial parts of either Bupleurum rigidum or B. fruticescens are equally used in certain parts of Spain for the treatment of topical and musculoskeletal inflammations. In the present paper, their phytochemical profile and pharmacological value has been compared. After chromatographic and spectral anal…
We present the preparation, structural and magnetic properties of nanosized magnetite obtained by the crystallization of a series of Fe-containing borosilicate glasses. Several compositions with the ratio Fe2O3/SiO2 spanning from 0.37 to 0.67 were investigated as a function of two nucleators Cr2O3 and P2O5, respective…
BACKGROUND: The low-temperature resistance aging performance of Yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) is the key effective factor that influences the long-term success rate of prosthesis. The objective of this study was to test and compare the aging performances for resisting low temperature of Lav…
The objective of this study was to analyse thesurface quality of black alder (Alnus glutinosa)samples as function of sanding processes based onfour grits sizes, namely 60, 80, 100 and 120. Thesanding process was performed parallel,perpendicular and at 45 degrees angle to the grainorientation of the specimens. The expe…
Abstract The Eunomia code is used to study the neutral species in and near a hydrogen plasma beam. Eunomia is a non‐linear Monte Carlo transport code that solves the neutral equilibrium, given a fixed background plasma. The code is developed to study the neutral inventory of Pilot‐PSI and Magnum‐PSI, linear devices de…
A temperature-sensitive hydrogel was successfully grafted on the surface of non-woven poly(propylene) materials. This was carried out by the application of unmodified β-cyclodextrin and N-isopropylacrylamide monomer in order to develop new functional hydrogels for textile science and technology. Graft polymerization t…
Abstract Transport of charge carriers in organic layers plays a relevant role in the performance of electronic devices such as light‐emitting diodes, solar cells, and photodetectors. The presence of energetically distributed traps severely affects the measured transport coefficient and the charge‐storage features in t…
In this contribution, we present a comparative study of the luminescence of the kesterites Cu2ZnSnS4(CZTS) and Cu2ZnSnSe4(CZTSe) and their related chalcopyrite Cu(In,Ga)Se2(CIGSe). Luminescence spectroscopy suggests that the electronic properties of Zn-rich, Cu-poor kesterites (both CZTS and CZTSe) and Cu-poor CIGSe a…
In this article, the biaxial buckling of a single layer graphene sheet is investigated. The model is established through the incorporation of an interatomic potential into non-local elastic plate theory to take into account the size effects and to circumvent the use of the Young’s modulus of a single layer graphene sh…
Corrosion assessment of metal waste form (MWF) alloys was carried out in two possible geological repository environments, simulated Kalpakkam groundwater (KGW) and Rajasthan groundwater (RGW). The corrosion resistance properties, passive film stability, and surface morphologies were evaluated by electrochemical and mi…
Au-assisted growth of InN nanowires (NWs) was accomplished by a simple chemical vapor deposition system. The as-prepared InN NWs exhibit two morphologies with different growth directions: periodic NWs (PNWs) and smooth NWs (SNWs) along <0001> and $ <\!\! 11\bar 20\! >$<112¯0>, respectively. The PNWs with crinoids morp…
We found that a single negative material has a character of zero-refraction in near field, and point out that the mechanism of a metal superlens to image with the resolution exceeding the diffraction limitation is different from that of a perfect lens made of a double negative material. The principle of metal superlen…
