In materials that are exposed to thermodynamic potential gradients, i.e., gradients of chemical potentials, electrical potential, temperature, or pressure, transport processes of the mobile components occur. These transport processes and the coupling between different processes are not only of fundamental interest, bu…
Our experiment shows that the thermal emission of phonon can be controlled by magnetic resonance (MR) mode in a metasurface (MTS). Through changing the structural parameter of metasurface, the MR wavelength can be tuned to the phonon resonance wavelength. This introduces a strong coupling between phonon and MR, which…
Gapless boundary modes at the interface between topologically distinct regions are one of the most salient manifestations of topology in physics. Metallic boundary states of time-reversal-invariant topological insulators (TIs), a realization of topological order in condensed matter, have been of much interest not only…
Concerns over reducing CO2 emissions associated with the burning of fossil fuels in combination with an increase in worldwide energy demands is leading to increased development of renewable energies such as wind. The installation of offshore wind power structures (OWS) is one of the most promising approaches for the p…
Fourier Transformed Infrared Spectroscopy (FTIR) was used to study the effect of water immersion of guar gum, gelatin and pektin films. Animal-derived gelatin, citrus-derived pektin and natural guar gum made from guar seeds was used to manufacture thin films (using a 2% concentration starting solution) by casting. The…
Case hardened, double-walled train wheel, produced in the foundry of Abraham Ganz in 1867 and used for long time on the railroad tracks, was studied and evaluated by modern methods of materials sciences. The investigations indicated the presence of 0.059m% antimony (Sb), distributed uniformly in the material of the wh…
The aim of this paper is a comparative study of the different geothermal power plant concepts, based on the energy and exergy analysis. The cycles studied in this paper are the combination of single and double flash power plants with two different ORC cycles as basic Organic Rankine Cycle (ORC), ORC with IHE, regenera…
The aim of this study was to investigate the effect of the previously applied cold rolling and the latter heat treatment for the eutectoidal decomposition of δ-ferrite in 2507 type superduplex stainless steel (SDSS). The samples were cold rolled at seven different deformation rates which was followed by heat treatment…
In this paper, Gas Turbine -Solid Oxide Fuel Cell (GT-SOFC) Aircraft Auxiliary Power Unit (APU) configuration is thermodynamically investigated. The system has a single stage centrifuge compressor, a heat exchanger, a jet fuel reformer, a SOFC, a combustion chamber and a turbine. The onboard kerosene fuel is converted…
Specimens of two kinds of isotropic nuclear graphite, IG-110U and ETP-10, were neutron-irradiated at fluence of 1.92 × 1024 n/m2 (E > 1.0 MeV) at 473 K. The recoveries of the macroscopic lengths of these specimens during isothermal and isochronal annealing at temperatures of up to 1673 K were investigated in a step-wi…
Abstract In this study, we utilized the metal vapor vacuum arc technique to implant vaporized aluminum (Al) ions in zinc oxide (ZnO) thin films. By adjusting the ion implantation dose and operational parameters, the conductivity and optical properties of the ZnO thin film can be controlled. The electrical sheet resist…
Nanotechnology is an emerging technology and it is related to various applications. Related to nanotechnology development, the use of green chemistry concept, low cost technology and sustainability is a must. Synthesis of nanoparticles using plant extract is a developing technique within the scheme. In this paper, stu…
Regular periodic stripe patterns that are found in the menisci of smectic C and C freely suspended films were described first by Meyer and Pershan (Solid State Commun. 13 (1973)) more than 40 years ago, but their physical origin is still under debate. Loudet et al. (Phys. Rev. Lett. 106 117, 802 (2011)) proposed a lay…
Microstructures of magnetic materials, including defects and crystallographic orientations, are known to strongly influence magnetic domain structures. Measurement techniques such as magnetic force microscopy (MFM) thus allow study of correlations between microstructural and magnetic properties. The present work probe…
The stochastic dynamics of individual co-doped Er:Yb upconversion nanoparticles (UCNP) were investigated from experiments and simulations. The UCNP were characterized by high-resolution scanning electron microscopy, dynamic light scattering, and zeta potential measurements. Single UCNP measurements were performed by f…
Al2O3/ZrO2 one-dimensional nanocomposite structures were synthesised by chemical vapour deposition using Al2O3 nanowires and a ZrCl4 powder source at a temperature of 800 °C and a pressure of 130 Pa. The samples were characterised using X-ray diffraction, the scanning electron microscopy, the transmission electron mic…
Abstract This paper presents a computationally efficient and robust nonlinear modeling framework for smart materials. The framework describes a smart material system through a new 3D inversion scheme for coupled nonlinear constitutive equations which can be integrated with the variational form of governing equations.…
The effect of different plastic deformation methods on the phase composition, lattice defect structure and hardness in 316L stainless steel was studied. The initial coarse-grained γ-austenite was deformed by cold rolling (CR) or high-pressure torsion (HPT). It was found that the two methods yielded very different phas…
This article aims at the investigation of the effect of five different parameters on the transport behavior of PP/jute yarn commingled eco‐composites. The high affinity of jute yarns to moisture (hydrophilic nature) favored the water absorption whereas xylene and toluene diffusion through PP/jute commingled system red…
The thermal expansion behavior of a metal-formate framework, Zn(HCOO)2·2(H2O) (1), has been systematically studied via variable temperature single-crystal X-ray diffraction. Our results demonstrate that this formate exhibits significant negative thermal expansion (NTE, −26(2) MK−1) along its c-axis. Detailed structura…
