The occurrence of high-Tc superconductivity in the iron pnictides shares a similar amorphous characteristic with that of high-Tc superconducting cuprates. Here we show that nearly frictionless (electric-field-driven) transport of condensed electrons in amorphous superconductors could happen after using the Eyring's tr…

We study hysteresis in temperature induced martensitic transformation using a 2D model solid exhibiting a square to rhombic structural transition. We find that upon quenching, the high temperature square phase, martensites are nucleated at sites having large non-affineness and ultimately invades the whole of the high…
Six crystal field energy levels obtained from the photoluminescence spectra of Yb3+-doped CuInS2semiconductor crystal are calculated from the diagonalization (of energy matrix) method. The root-mean-square (r.m.s) deviation σ is 4.5 cm-1and so the calculated results are in good agreement with the experimental values.…
To realize next generation functional devices, atomic level controllability of the application and fabrication techniques is necessary. The conventional route to advance solid state devices, which involves improvement of 'instrumental accuracy', is now facing a major paradigm shift towards 'phenomenal accuracy'. There…
This standard describes the LLNL Fire Protection Facility Survey Program. The purpose of this standard is to describe the type of facility surveys required to fulfill the requirements of DOE Order 420.1B, Facility Safety. Nothing in this standard is intended to prevent the development of a FHA using alternative approa…
The destruction of Landau levels of one-dimensional graphene nanoribbons in a modulated magnetic field is investigated by the Peierls tight-binding model. The partial flat subbands are transformed into oscillating parabolic subbands, and the dispersion is very sensitive to the modulation period and the field phase. Th…
It is shown that the molybdenum compounds are good catalysts for oxygen electrodes of power cells based on carbon nanotubes working in the alkaline electrolyte. With the help of electrochemical method were obtained molybdenum compounds applied to multiwalled carbon nanotubes. It was established that it was a compound…
The aim of this paper is to describe hybrid pulsed laser magnetron technology (PLDMS) for deposition of both TiC and TiCN thin films. Films were fabricated in argon atmosphere (TiC) and argon/nitrogen mixtured atmosphere (TiCN). Titanium carbide based materials exhibit an unique combination of physical properties such…
In order to obtain an AC electrical model of polyfluorene-PEDOT poly(3,4-ethylenedioxythiophene) based organic light emitting diodes, different devices have been realized using three PEDOT dispersions. Static current-voltage characteristics have revealed exponential like transport in all the samples and the bias has s…
AlN nanowire macro-arrays are successfully synthesized and characterized by the second template method. In the article we mainly research the process of preparing the AlN nanowire macro-arrays each with a certain orientation and uniform diameter by the chemical vapor deposition (CVD) method. Metal nanoparticles are pr…
Absolute photoabsorption spectrum of CO molecule in the region 14-20 eV (620-890 angstrom) is measured using synchrotron radiation and multi-stage photoionization chamber, and its ionization energy is obtained. According to the absorption spectrum of CO and theoretical calculation, the Rydberg series converging to the…

Abstract Intrinsically disordered proteins (IDPs) represent a growing category of proteins, especially in the eukaryotic proteomes. They are linked to a wide variety of biological functions, including those which are commonly impaired in cancer and neurodegenerative diseases. Since IDPs by definition do not adopt a we…
Recently, a new carbon modification, namly n-diamond, have been reported, whose structure is still a matter of debate. It is important to note that the synthesis of n-diamond was carried out in the presence of hydrogen or methan. In this work we evaluate the structural stability of five fcc-CHx phases by means of firs…
A simulation environment for metallic nanostructures based on the Discontinuous Galerkin Time Domain method is presented. The model is used to compute the linear and nonlinear optical response of split ring resonators and to study physical mechanisms that contribute to second harmonic generation .
A novel design method of the improved broadband harmonic filter for diode rectifier type adjustable speed drives using genetic algorithm is presented. The design yields high input and output power quality while reducing the filter size, cost and avoiding resonance problems. Results are illustrated using computer simul…
The recently discovered superconductor CuxBi2Se3[1] is a candidate for three-dimensional time-reversal-invariant topological superconductors[2], which are predicted to have robust surface Andreev bound states hosting massless Majorana fermions. In this work, we present an analytical and numerical study of the surface…
Abstract Transition metal alkane‐thiolates [i.e., organic salts with formula Me(SR)x, where R is a linear aliphatic hydrocarbon group, −CnH2n+1] undergo a thermolysis reaction at moderately low temperatures (close to 200°C), which produces metal atoms or metal sulfide species and an organic by‐product, disulfide (RSSR…
This paper presents the process of selecting a semi-empirical fuel cell (FC) model for use in a realtime virtual PEM fuel cell system. A selection of FC models are reviewed using a list of key features and considering the final application of the model within a virtual fuel cell system (VFCS). As the model is intended…
