We have demonstrated a methodology to generate large area graphdiyne films with 3.61 cm(2) on the surface of copper via a cross-coupling reaction using hexaethynylbenzene. The device based on graphdiyne films for measurement of electrical property is fabricated and shows conductivity of 2.516 x 10(-4) S m(-1) indicating a semiconductor property.
Carbon nanofiber (CNF), as one of the most important members of carbon fibers, has been investigated in both fundamental scientific research and practical applications. CNF composites are able to be applied as promising materials in many fields, such as electrical devices, electrode materials for batteries and supercapacitors and as sensors. In these applications, the electrical conductivity is...
This paper gives an overview of nowadays used simulation models and measurement methods in order to determine iron losses in electrical machinery. The paper provides machine designers and system engineers with an overview of suitable iron loss models applicable for the machine design process and simulations. Furthermore, possible methods for iron loss measurements in electrical machines are pre...

The methods of acoustic spectroscopy are powerful tool for the study physical properties of condensed matter. The ability of these methods makes it possible to obtain important information for variety of materials concerning not only their mechanical properties. The theoretical principles of acoustic spectroscopy of some kinds of materials and structures perspective for application in electrica...
This paper presents a modal analysis of a uniaxial grounded chiroslabguide. A dispersion model with a single resonance is used to describe the physical properties of the chiral uniaxial medium. We show that proper leaky modes can propagate regardless of the sign (positive or negative) of the medium’s parameters. Furthermore, proper leaky modes can also occur as a consequence of electromagnetic ...
Transition metal dichalcogenides (TMDs) WTe2 and MoTe2 with orthorhombic Td phase, being potential candidates as type-II Weyl semimetals, are attracted much attention recently. Here we synthesized a series of miscible Mo1-xWxTe2 single crystals by bromine vapor transport method. Composition-dependent X-ray diffraction and Raman spectroscopy, as well as composition and temperature-dependent resi...
Discontinuous changes in the electronic structure upon infinitesimal changes to the Hamiltonian are demonstrated. These are revealed in one and two electron molecular systems by full configuration interaction (FCI) calculations when the realm of the nuclear charge is extended to be fractional. FCI electron densities in these systems show dramatic changes in real space and illustrate the transfe...
