In an in situ powder-in-tube (PIT) fabrication of MgB2 superconducting tapes, it has been found that ball-milling treatment on a starting powder is effective for improving critical current density (Jc) of the MgB2 tapes. In the present study, microstructures/nanostructures of MgB2 tapes and the mechanism of the Jc enh…
Metal-based photonic structures have extraordinary potentials in many applications. However, the processing difficulty of metals remains a major obstacle in this field. Here we report a facile method for constructing of porous Ni films by templating porous Si (P-Si) photonic structures. The P-Si templates were fabrica…

In this work, we show how the absporption cross-section of a dipole nano-antenna is modified by the local environment. In particular, we clarify the key role of the Local Density of States (LDOS) and show the analogy that exists with quantum emitters. This link with the LDOS shows that it is possible to probe the LDOS…
This paper presents the results of the study of the properties of epoxy-bonded joints. Depending on the parameters of cure cycles the epoxy adhesive film has got various mechanical properties. When it is possible to use cure parameters suggested in the data sheet of the adhesive film the best results are obtained. How…
We observe metamaterial induced transparency in a single Fano resonator array. In a perfect symmetric configuration, a broad dipolar resonance is excited whereas a high Q transparency window opens as the structural symmetry is broken.
A porous solid's initial state is off the thermodynamic surface of the solid to start with but when pressure is high enough to cause total pore collapse or crush up, the final states are on the thermodynamic surfaces. The Hugoniot for the fully compacted initially porous solid has pressure above the principal Hugoniot…
(Nd, Eu, Gd)-Ba-Cu-O ternary bulk superconductors have high potential for practical applications since they exhibit very high critical current densities and thus high field trapping capabilities. (Nd, Eu, Gd)-Ba-Cu-O superconductors are synthesized in a reduced oxygen atmosphere, which requires a control of oxygen par…
A dedicated four-quadrant regenerative experimental test rig was built to perform various tests on a 15-phase Active Stator machine and its associated drive system. Machine no-load characteristics were investigated and a number of on-load tests were conducted for both motoring and generating modes of operations. The m…

The behavior of a transmission function for energy analyzers of spectrometers with power-type potentials is considered. It is established that an integral relationship between the measured current and true spectrum of electrons as mediated by the transmission function is described by a first-order Volterra integral eq…
SiC/SiC composites are promising materials for the plasma-facing walls in a fusion reactor. In order to investigate the effect of helium ion irradiation on the deuterium retention behavior of SiC/SiC composites, helium ion irradiation followed by deuterium ion irradiation was performed on SiC/SiC composites using an E…

We investigated molecular arrangement of organo-modified aluminosilicate with high surface coverage in Langmuir-Blodgett (LB) films by performing out-of-plane and in-plane X-ray diffraction (XRD) measurements. In addition, the surface morphology of mixed monolayers of organo-modified aluminosilicate and several biodeg…
We report the superconducting properties of single-crystalline Ba(Fe1-xRux)2As2 by measuring its resistivity, upper critical field, magnetization, and magneto-optical images. Ba(Fe1-xRux)2As2 single crystal shows superconductivity at ∼ 20 K. The upper critical field determined by resistive transition is anisotropic wi…
The influence of electron radiation on the properties of semiconducting silicon single crystals (Si)—both n- and p-types (currently one of the most widely applied material in the electronic technology) was studied under the electron irradiation process in-situ in air (in common conditions). Higher value of electro-con…

Low-pressure alcohol catalytic chemical vapor deposition (LP-ACCVD), which is an ACCVD method at a lower pressure (<1 Pa) than that in the conventional method, has been attracting much interest because it enables the low-temperature growth of single-wall carbon nanotubes (CNTs). However, the growth rate of CNTs by LP-…
In the scope of material science, it is well understood that mechanical behavior of a material is temperature dependent. The converse is also true and for specific loading cases contributes to a unique thermal failure mechanism known as “heat explosion”. The goal for this paper is to improve the mathematical models fo…
A numerical simulation study was carried out to investigate the relative contributions of thermal and solutal Marangoni convections on transport structures in a liquid bridge under zero gravity. The liquid bridge in the model represents a three dimensional half-zone configuration of the Floating Zone (FZ) growth syste…
