One of novel combustion technologies for low emissions and highly efficient internal combustion engines is combustion in porous reactors (PM). The heat release process inside combustion reactor is homogeneous and flameless resulting in a nearly zero emissions level. Such combustion process, however is non-stationary,…
We demonstrate a new scheme of aspherical microlens (ASM). By employing a single-step grinding with fully automatic technique to precisely and quantitatively control the grinding offset less than 0.5 µm and minor radius of curvature within 2.4 - 3.5 µm, the ASMs exhibited a high-average coupling efficiency of 84.5%. T…
Thin films of Cobalt(II) Oxide were deposited from equimolar concentrations of Cobalt Chloride, and Hexamethylenetetramine on clean glass substrates using the Aqueous Chemical Growth method in order to determine the effect of precursor concentration on their optical and solid state properties. The analytical tools use…
NdNiO3 thin films have been grown on c- axis oriented LaAlO3 single substrates using pulsed laser deposition technique. Raman spectroscopy data confirms the formation of NdNiO3 phase. Along with φ-scans, XRD θ-2θ measurement reveals the highly c-axis oriented epitaxial growth of NdNiO3 films on the LaAlO3 substrates.…
The dependence of film composition, microstructure and magnetic properties on the deposition pressure was investigated during the sputtering of Sm-Co films over Si(100) substrates. The morphology of Sm-Co films in terms of grain size and surface roughness were significantly affected by the increase in gas pressure. Up…
Starting with the U(1)-gauge covariant four-dimensional Dirac equation, we derive the analytic solutions describing the chiral massless fermions evolving in static orthogonal magnetic and electric fields. Working in cylindric coordinates, we compute the electric current density essential component and the off-diagonal…
The magnetic states of Cobalt ions in magnetic thermoelectric materials of Bi 1.5 Pb 0.5 Ca 2-z Y z Co 2 O 8 (z = 0, 0.1, 0.2, and 0.3) have been studied from the structural (X-ray diffraction) and magnetic susceptibility data. The misfit structure was revealed from refinement of the XRD data, with reduction of the la…
The technological properties of urea formaldehyde resins modified by polyvinylacetate are presented.
GaDyN single layer and GaDyN/AlGaN multi-quantum well (MQW) structures are grown on GaN templates by radio-frequency plasma-assisted molecular-beam epitaxy (RF-MBE). X-ray diffraction θ/2θ scan curves exhibited well-defined satellite peaks for the MQW structure samples. From analyzing extended x-ray absorption fine st…
Defect centers in diamond are regarded as a promising candidate for future solid state quantum technology. In particular the nitrogen vacancy (NV) center attracts researchers attention, as it promises to emit indistinguishable single photons and provides a triplet ground state with ultra long spin coherence times. In…
The number of vehicles applied diesel engine are rapidly rising for fuel economy. Accompanying this trend, application of an after-treatment system is strictly required as a result of reinforced emission regulation. The Diesel Particulate Filter (DPF) system is considered as the most efficiency method to reduce partic…

We experimentally demonstrate a new coherent absorption phenomenon, through which a planar photonic metamaterial may resonantly absorb 100% of incident light. The effect is a time-reversed analogue ‘Lasing Spaser’ action.
Traveling-wave magnetic field generated by a linear motor is a typical AC time-varying field. In order to identify the trapped magnetic flux attenuation characteristics of the high temperature superconducting (HTS) bulk magnet exposed to the external traveling-wave field generated by the primary of a developed HTS lin…

0.85PbMg1/3Nb2/3O3–0.15PbTiO3 (0.85PMN–0.15PT) ferroelectric relaxor thin films have been deposited on La0.5Sr0.5CoO3/(111) Pt/TiO2/SiO2/Si by pulsed laser ablation by varying the oxygen partial pressures from 50 mTorr to 400 mTorr. The X-ray diffraction pattern reveals a pyrochlore free polycrystalline film. The grai…
Abstract CuO-CoO-MnO/SiO2 nanocomposite aerogels were prepared by using tetraethyl orthosilicate (TEOS) as Si source, and aqueous solution of Cu, Co and Mn acetates as the precursors via sol-gel process and ethanol supercritical drying technique. Supported catalysts were prepared by using CuO-CoO-MnO/SiO2 nanocomposit…
In principle, embedded wire-element lateral manganin pressure gauges allow the lateral component of stress during shock loading to be directly monitored. However, such gauges require target materials to be sectioned before insertion into an encapsulating MylarTM/epoxy layer, leading to debate over their analysis. In p…
The aim of this paper is to propose the simple Plane-Cap (PC) model as well as to classify an accuracy of analysis for the response of the reinforced mortar beam subjected to low velocity impact loading. The present study deals with the Smoothed Particle Hydrodynamics (SPH) method by employing Drucker-Prager (DP) with…
