The thermal evolution of the electric field-induced birefringence, δ(Δn(E)) vs T, obtained by the Kerr and Pockels electro-optical effects, was characterized in the La-doped Pb(Mg1/3Nb2/3)O3 – PbTiO3 ferroelectric relaxor ceramic system. The measurements were conducted over a broad temperature range (from 100 K to 650…
Abstract A microwave (MW) roasting experiment of agglomerated flux for submerged-arc welding was carried out. The MW heating characteristics of agglomerated flux and influence of roasting temperature on weld surface were investigated. It was found that the heating rate of agglomerated flux becomes faster with the incr…
Using a full band Monte Carlo simulation the electron energy relaxation times of InAs nanowires along the [100] direction are shown to be greater than the energy relaxation time of bulk InAs. The full band structure and scattering rates of the nanowires are calculated using the sp 3 d 5 s* tight binding method and Fer…
The effects of high-energy external influences on structural heredity of Ti-Nb alloy is investigated in this paper. By the methods of XRD, SEM, EDX and optical microscopy it was founded that thermal treatment and severe plastic deformation lead to the phase transformations in the alloy, the dendritic segregation occur…
Nowadays there is a lack of experimental data describing the physical process of drop spreading on a solid metal surface for developing wetting and spreading theory. The experimental data obtained by using the high speed video-recording will allow to identify unknown previously spreading modes as well as the change of…
A study of experimental measurement and numerical simulation was carried out with respect to 45 steel shaft work piece in the high-frequency induction heating cladding process. Firstly, the model domain boundaries were divided in according to material characteristics. Secondly, the electromagnetic model and the therma…
This study shows that forward scattering at the origin of reciprocal space contributes to the scattering intensity profiles of ultra-small-angle scattering. The forward scattering corresponds to a Fourier transform of the X-ray coherent volume on a sample. This contribution is usually ignored in the study of small-ang…
To examine the effect of crystal size and orientation effect on ZT, polycrystalline NaxCo2O4 materials were prepared by pressing layered crystals obtained in sol–gel (SG) synthesis, molten salt synthesis (MSS) with and without additional ball milling (BM) treatment and 1:1 molar ratio mixture (Mixture) of BM powder an…
Polycations with macrocounterions present unique scaling relation in rheology. The observable size of macrocounterions in dynamic light scattering helps further investigate the bimodal relaxation of polyelectrolytes.
Straw powders were blended with hydrolyzed soy protein isolate (HSPI) modified urea-formaldehyde (UF) resins to produce biodegradable seedling containers. The tensile strength and the degradability of the seedling containers were characterized. Moreover, the degradation behavior of modified UF resins was investigated…

The dependences of the microstructure and physical and mechanical properties of ceramic mixtures Si 3 N 4 /TiN in the full range of mass ratios of the components. Was also investigated directly, and the process of sintering occurring during a physical or chemical processes, in particular, has been obtained and the har…
Silicon carbide (SiC) nanoparticles can be used for ceramics reinforcement, creation of nanostructured ceramics, microelectromechanical systems.The paper presents the results of plasmadynamic synthesis of silicon carbide nanopowders.This method was realized by the synthesis in an electrodischarge plasma jet generated…
This paper explores self-heating effects on junctionless gate-all-around nanowire MOSFET using self-consistently coupled 3D full band electro-thermal transport. The self-consistent algorithm begins by supplying the heat generation data from the 3D electron Monte Carlo with 2D quantum correction to the phonon Monte Car…
In the present study the effects of stress-assisted aging of the Ti 49.2 Ni 50.8 single crystals oriented along [ 11] direction on the stress-induced B2-R-B19' thermoelastic martensitic transformations and superelasticity are investigated. It is experimentally established that aging at 823 K for 1h under compression s…
Recent advances in solid-state nuclear magnetic resonance (NMR) techniques, such as magic angle spinning and high-power decoupling, have dramatically increased the sensitivity and resolution of NMR. However, these NMR techniques generate extra heat, causing a temperature difference between the sample in the rotor and…
Modulation of the band gap energy and diameter of quantum dots ( QD s) formed in glasses is important to achieve the optimized performance for applications as infrared light sources, lasers, saturable absorbers, etc. Absorption and photoluminescence of PbS QD s were extended into mid‐infrared wavelength range in glass…
Environmental context Nanoparticles are present in growing volumes of consumer products and are suspected to be released into the environment at detectable levels. We focus on cerium dioxide nanoparticles and investigate their availability to fish from the water column, where we found increasing concentrations of natu…
Ultralow stability of gold clusters prohibits the understanding of their intrinsic reactivity (that is vital for revealing the origin of gold's catalytic properties). Using density functional theory including many-body dispersion method, we aim to ascertain effective ways in exploiting gold clusters' intrinsic reactiv…
The diagram of phase equilibria in the BaB2O4–NaF system has been used to deduce the relationship between the cooling speed (ΔT), the pulling speed (v), the crystal radius (Rs), the slope of liquidus (m), the solution component (x) and the total quantity of melt, namely ΔT= 0.00159Rs2vmx2/G. The theoretical curves of…
