We investigate the spin texture of Andreev bound states and Majorana bound states in long superconductor-normal (SN) and superconductor-normal-superconductor (SNS) junctions, and we show that measuring the spatial dependence of the spin polarization in the normal region allows one to identify the transition from the n…
We have investigated thermal conductivity of graphene laminate films deposited on polyethylene terephthalate substrates. Two types of graphene laminate were studied - as deposited and compressed - in order to determine the physical parameters affecting the heat conduction the most. The measurements were performed usin…
We present the orbital resolved electronic properties of structurally distorted 1T-TaS2 monolayers. After optimizing the crystal structures, we obtain the lattice parameters and atomic positions in the star-of-David structure, and show the low-temperature band structures of distorted bulk are consistent with recent an…

We developed a method for production of arrays of platinum nanocrystals of controlled size and shape using templates from ordered silica bead monolayers. Silica beads with nominal sizes of 150 and 450 nm were self-assembled into monolayers over strontium titanate single crystal substrates. The monolayers were used as…
Aiming at the characteristics and current status of refineries’ odor pollution, the sulfur containing odor gas–hydrogen sulfide was chosen as a typical object and treated by using the adsorption-catalytic oxidation method in the laboratory. This research focused on the preparation of adsorptive catalyst with high sulf…
Zone refining, using a locally-melted zone by high-frequency induction heating, was utilized to purify neodymium (Nd) metal. The traveling rate of the molten zone was set as a parameter during zone refining process. The purification efficiency for each impurity (Al, Cu, Fe, Mn, Se, Ti) in the Nd specimen was analyzed…
Effect of Peierls instability on the electronic band structure of carbon nanotubes (CNTs) under torsional strain is studied by tight-binding approximation. When Kekulé structure with two different bond lengths is introduced, armchair (5,5) and zigzag (9,0) CNTs become semiconducting indicating by a small band gap open…
Recently, three-dimensional microstructures have been attracting much attention because of their potential application to electromagnetic devices operating with specific frequencies such as THz wave. For suitability in such applications, the structures often need to have complex three-dimensional shapes, be smaller th…
The drug-protein interaction has been the subject of increasing interest over the decades. In the present communication, the interaction of liver cystatin with anti-cancer (adriamycin) and anti-hepatitis (adevofir dipivoxil) drugs was studied by thiol-protease inhibitory assay, UV absorption, fluorescence spectroscopy…
Nitrogen-doped nanoporous carbon has been produced by the carbonization of a 5-[(4-nitrophenyl)azo]salicylate–zinc complex, which is prepared by mixing Zn2+ ion and sodium 5-[(4-nitrophenyl)azo]salicylate in aqueous solution. Furthermore, zinc metal was added to the complex before carbonization to improve the electroc…
A model has been developed based on the available experimental data for propylene polymerization with long‐chain branching. The system considered is a bicatalyst system, where the first catalyst produces the atactic polypropylene macromonomer and second one grafts the atactic polypropylene macromonomers to isotactic p…
The stochastic formulation of multiexciton generation (MEG) rates is extended to provide access to MEG efficiencies in nanostructures containing thousands of atoms. The formalism is applied to a series of CdSe/CdS seeded nanorod heterostructures with different core and shell dimensions. At energies above 3Eg (where Eg…
In attempts to replace the conventional trial-and-error heavy-atom derivative search method with a rational approach, we previously defined heavy metal compound reactivity against peptide ligands. Here, we assembled a composite pH- and buffer-dependent peptide reactivity profile for each heavy metal compound to guide…
Here we report the preparation and characterization of a green composite based on high‐density polyethylene and Kaans grass (Saccharum spontaneum). The composites were prepared by conventional melt‐mixing method, using maximum loading of Kaans grass in powder form (KG‐filler) to achieve acceptable range of required pr…
Materials of the future will exhibit bio-inspired behavior that enables a range of novel applications. We review computational studies on reactive gels that reveal how to tailor the gels and external stimuli to impart this biomimetic functionality. For example, photo-responsive gels can be ‘molded’ by light into vario…
In this article, we develop a quantitative comparison method for two arbitrary protein structures. This method uses a root-mean-square deviation characterization and employs a series expansion of the protein's shape function in terms of the Wigner-D functions to define a new criterion, which is called a "similarity va…
BACKGROUND: Kashin-Beck disease (KBD) is a chronic, degenerative osteoarthropathy that causes severe skeletal deformation. Although many researchers have proven that almost all KBD patients who showed an increaseing proximo-distal gradient had radiographic abnormalities of the ankle, few detailed description of radiog…
This article presents an experimental study of bending properties of multilayer‐connected biaxial weft knitted (MBWK) fabrics‐reinforced composites made with carbon fibers. Three types of composites are used in bending test, which are three‐layer‐connected biaxial weft knitted fabric‐reinforced composite, four‐layer‐c…
