To prepare magnetic anisotropic nanostructures, the films of porous alumina obtained by the two-step anodization technique were used as the matrix in this work. The electrocrystallization of metals in porous alumina allowed us to form threadlike nanoparticles with narrow size distributions and controllable geometric a…
We performed a precise analysis on the titanium (Ti) liner effect on copper resistivity in comparison with Ta liner. The grain size and Ti distribution in the copper interconnects using the Ti liner were investigated by electron backscattering deflection (EBSD) and micro auger electron spectroscopy (µ-AES). It was fou…
The paper presents the results of studying the combined shock-wave radiation-emission processes associated with cavitation phenomena that occur at fast directional motion of a liquid jet into a closed working chamber through narrow dielectric channels. These processes induce high-power tunable X-ray radiation outside…
Er3+/Yb3+ co-doped TiO2 nanocrystals were prepared by Sol-gel method in which titanium tetrachloride was adopted as the precursor. The structure, particle size, and optical properties of samples were characterized by X-ray diffraction(XRD), Field emission-Scanning Electron Microscopy(FE-SEM) and photoluminescence(PL)…
The temperature dependences of the dielectric permittivity and conductivity of nanocomposites on the basis of nanoparticles of copper sulfide and a polymer matrix (polyvinyl alcohol) were investigated in the frequency range of 265 Hz-1 MHz. The activation energies of the charge carriers were determined using the tempe…
We have investigated the electronic structures and magnetic properties of La2MnNiO6 that is a typical ferromagnetic insulator with the double perovskite structure. We have examined the valence states of Mn and Ni ions using the full-potential linearized augmented plane wave band method. The density of states as well a…
We present a set of three posters to give an overview of "The harmonics in power systems", with a synthesis study on three aspects: Poster 1: "Harmonics in power systems: generalities".
Abstract The X‐ray diffraction (XRD) pattern from gallium phosphide (GaP) nanoparticles showed the presence of the diamond (111) diffraction peak. Analysis of the Raman scattering of GaP nanoparticles revealed that disordered graphite displayed a wide band at 1572 cm –1 assigned to the E 2g mode, and diamond displayed…
Significantly enhanced superbroadband near infrared emission has been realized in bismuth/aluminum doped high-silica zeolite derived nanoparticles. The emission intensity can be easily tailored by the introduction of aluminum. The luminescence lifetime can reach up to 695 micros. The results reveal that the existence…
The successful growth of suspended carbon nanotubes is normally based on purely empirical results. Here we demonstrate the ability to predict the successful suspension of nanotubes across a range of trench widths by combining experimental growth data with a theoretical description of nanotube mechanics at the growth t…
In this work the effect of nano-magnesium hydroxide (nano-Mg(OH)2) on the flammability of epoxy composites is presented and compared with the traditional flame retardant used in just small amounts for epoxy resins, ammonium polyphosphate (APP). The fire reaction properties of epoxy composites were obtained by cone cal…
Surface plasmon, which is induced by the oscillation of free electrons at the surface of a metal, generates remarkable enhancement of localized electric field owing to its interaction with the incident light field, which is called localized surface plasmon resonance (LSPR). In this study, we have fabricated densely pa…
This study investigates the influence of various nanofillers of different shapes and sizes on the properties of PET nanocomposites. PET was reinforced with 0.3 wt.% of different nanoreinforcements, namely: (i) 1D platelet-like shape of organo-modified layered silicates (montmorillonite) (platelet size approx. 1 x 200…
Decorating one-dimensional micromaterials with nanoparticles provides an effective method to manipulate and integrate their physicochemical and optoelectronic properties. Here, we demonstrate an example of photochemical deposition of Au core/Ag shell nanoparticles onto ZnO microrods (ZnO/Au@Ag). The as-prepared microm…
Synthesis of silicon carbide and diamond nanoparticles is studied during short-pulse implantation of carbon ions and protons into a silicon target. The experiments are carried out using a TEMP source of pulsed powerful ion beams based on a magnetically insulated diode with radial magnetic field B r . The beam paramete…
The lightness of magnesium makes it an attractive material for applications where weight reduction is critical, in particular, consumer electronics and transportation industries. Despite its advantages as a material the use of magnesium worldwide is a tiny fraction of other materials (steel, plastic, aluminium). Among…
Abstract Bis(tetrabutylammonium)bis(2‐thioxo‐1,3‐dithiole‐4,5‐dithiolato)mercurate(II) was prepared and characterized by elemental analyses, electronic absorption, infrared and X‐ray powder diffraction spectroscopy. The specific heat of the crystal was measured to be 1878.2 J.mol –1 K –1 at 300 K. The thermal decompos…
The beneficial aspects of enhanced or extended heat transfer surfaces may be offset if operated under fouling conditions. In this article, preliminary experimental results for crystallization fouling of CaSO4 solutions onto surfaces with different structures are reported. Flat stainless steel plates (50 mm × 59 mm) wi…
We have studied the thermal stability of five potassium strontium vanadates: KSr(VO 3 ) 3 , K 2 Sr(VO 3 ) 4 , K 4 Sr(VO 3 ) 6 , K 6 Sr(VO 3 ) 8 , and KSrVO 4 . The double orthovanadate undergoes a reversible polymorphic transformation at 1117°C and is stable up to 1500°C. The double metavanadates melt peritectically i…
The bacterial tyrosine phenol-lyase (EC 4.1.99.2) and tryptoptophan indole-lyase (EC 4.1.99.1) belong to pyridoxal-5'-phosphate dependent beta-eliminating lyases, catalysing the reversible decomposition of L-tyrosine and L-tryptophan to pyruvate, ammonia, and phenol or indole correspondingly. Data on the three dimenti…
