to test the null hypothesis that patients with the terrible triad of the elbow (dislocation together with fractures of the radial head and coronoid process) who are treated with open reduction and internal fixation of the radial head have final results that are comparable with those of patients treated with arthroplas…
In this paper, a polymer matrix composite method by mixing printable polymer with a number of possible nanoparticles is investigated to achieve artificially controlled effective electromagnetic properties for 3D additive manufacturing applications. The material properties are evaluated using effective medium theory. T…
The interrupted creep behaviour of single crystal superalloy DD6 was studied at 980°C/220 MPa by TEM. The results show that Al and Ta diffuse to the position of the γ phase, which promotes γ′ phase growth. Meanwhile, Re diffuses from the γ phase to the γ′ phase. After creep for 150 h, γ′ phases merge to a raft structu…
An Infrared imaging Video Bolometer (IRVB) diagnostic is currently being used in the Large Helical Device (LHD) for studying the localization of radiation structures near the magnetic island and helical divertor X-points during plasma detachment and for 3D tomography. This research demands high signal to noise ratio (…
The current design studies on sodium-cooled fast reactors (SFRs) are breaking with the past since they are guided by a new set of design criteria arising from the objectives of Generation IV reactors. The new safety requirements lead to designing reactors with breakeven breeding cores because in terms of reactivity co…
We propose an ac current source that can be tuned from a pure charge to a pure spin current source. The device consists of two mesoscopic capacitors attached to a two-dimensional strip of a topological insulator. The change from charge to spin current is controlled by an offset in the top gate potentials that drive th…
The structure and properties of carbon-filled composite materials for tribological applications based on ultrahigh molecular weight polyethylene that are obtained by deformation-induced solid-phase synthesis are investigated. It is shown that the addition of graphite and carbon fiber to a polymer material allows one t…
This paper summarizes the results of an experimental program aimed at investigating of the mechanical properties of composites based on aluminous cement for high-temperature applications and deal with the influence of high-thermal loading on polycarboxylate superplasticizing (PCSP) additive contained in the composite.…
Three-phase induction motors are the “workhorses” of industry; they are the most widely used electrical machine; because of its simple structure and high reliability. This paper proposes a new technique to model the stator winding of the induction motor in Matlab Simulink® software. This simulation of the induction mo…
Current induced domain walls (DW) motion in magnetic nanowires or nano-stripes presents a novel approach to store and convey data. Combining with magnetic tunnel junction (MTJ) nanopillars, Racetrack memory (RM) becomes a new class of non-volatile memory thanks to its large storage capacity and fast data access. Howev…
In this work, novel ionic gel conductive polymers were synthesised using thermally and UV-light induced polymerization. The gel polymers are based on poly(methyl methacrylate) (PMMA) containing ionic liquids (IL) and conductive salt (lithium bis(trifluoro-methanesulfonyl)imide, LiTFSI). Additional acrylates like 2-eth…
The present study investigated the effects of initial Hydrogen level and cooling rate on ultimate tensile strength of commercial Al-A319 alloys. Three hydrogen levels (0.01, 0.2, and 0.41 mL/100 grams of melt) and five cooling rate were studied. Total of 45 tensile test bars was prepared (three hydrogen levels × five…
Bacterial cellulose (BC) has become established as a remarkably versatile biomaterial and can be used in a wide variety of scientific applications, especially for medical devices. In this work, the bacterial cellulose fermentation process is modified by the addition of chondroitin sulfate and hyaluronic acid (1% w/w)…
CO 2 -laser welding of 12Kh18N10T stainless steel and a VT1-0 titanium alloy with the use of a composite insert obtained by means of explosive welding of four sheets (VT1-0 titanium, high-purity tantalum, M1 copper, and 12Kh18N10T steel) is experimentally studied. After mechanical processing, the insert is placed betw…
Numerical experiments are systematically carried out using the Lee model code extended to compute the ion beams on various plasma focus devices operated with Deuterium gas. The deuteron beam properties of the plasma focus are studied for low and high energy plasma focus device. The energy spectral distribution for deu…
This paper provides oil properties study of conventional diesel engine oil enriched with hBN/Al2O3 nanoparticles. In this study, an optimal composition (0.5 vol.%) of hBN and Al2O3 nanoparticles separately dispersed in SAE 15W40 diesel engine oil by sonication technique. The oil properties were studied by measuring th…
The properties of Electromagnetic Band-Gap (EBG) structures are used to alter the scattering fields by combining Perfect Electric Conductor (PEC) and EBG structures on the same ground plane. Due to the anti-phase property, the reflected energy can be re-directed toward four quadrants and a null to appear toward the no…
Published data on thermodynamic properties, structure, and applications of liquid mercury-sodium alloys are discussed.
Results of dielectric investigations of onion‐like carbon (OLC) and detonation nanodiamond (DND)/polydimethysiloxane composites in wide frequency (20 Hz–3 THz) and temperatures (26–300 K) ranges are presented. The percolation threshold in OLC composites is 6.8 vol%. Electrical conduction in the OLC composites above th…
In our work, we aimed to improve the interfacial properties of the Polyetheretherketone (PEEK) polymer/carbon fiber (CF) by treating the fibers with wet chemical method, a higly oxidative chemical solutions called piranha solution and chromate solution. The changes of the surface funtional groups, chemical composition…
