We investigate theoretically the infrared optical response characteristics of metallic armchair/zigzag-edge graphene nanoribbons (A/ZGNRs) to an external longitudinally polarized electromagnetic field at low temperatures. Within the framework of linear response theory at the perturbation regime, we examine the optical…
Here we report on the results of a research project focused on the reduction of formaldehyde emissions from wood-based panels, by using a novel set of adhesive formulations based on dimethoxyethanal (DME)-derived resins. The investigated adhesives were evaluated on laboratory scale in order to study their technical pe…
For a promising approach to improve the energy conversion performance of organic thin layer solar cells, a buffer layer between a hole collecting electrode (anode) and organic active layer containing electron accepting and donating materials mixture is investigated. A conductive polymer, PEDOT:PSS, is generally used a…
The crystal structure of the ternary iodide Cs2TeI6 has been refined by Rietveld analysis of X-ray powder diffraction data. The refinement procedure was stopped when the intensity residual RB = 3.7 % had been reached. Cs2TeI6 crystallizes in the cubic K2PtCl6 structure type, space group Fm-3m (No. 225), with the latti…
Photoluminescence properties and surface morphologies of porous silicon etched with various applied current densities at fixed etching times. FE-SEM image of porous silicon surface indicated that the porous silicon prepared at currents below 200 mA exhibited very bright red photoluminescence properties. As the applied…
Microwave absorbing coating samples were fabricated with carbon nanotube （CNT） and nanoscaled tetrapod-shaped ZnO （NT-ZnO） as the absorbents and epoxy resin as the binder. The influence of the content of CNT and NT-ZnO in the absorbing coatings on microwave absorbing property was investigated. After 3-layer coating, w…
Polystyrene thin films containing Bragg structures have been successfully obtained by the removal of DBR porous silicon films from the DBR structured porous silicon/polystyrene composite film in HF/ mixture solution and by replicating the nano-structures of porous silicon containing Bragg structure. Polystyrene thin f…

The radial thermal expansion αr of bundles of single-walled carbon nanotubes saturated with ⁴He impurities to the molar concentration 9.4% has been investigated in the interval 2.5–9.5 K using the dilatometric method. In the interval 2.1–3.7 K α r is negative and is several times higher than the negative αr for pure n…
High voltage power transmission faces the problem of high altitude in China. In this paper, a mobile corona test cage is firstly applied to measure the AC corona audible noises of three types of transmission bundle lines in four areas with different altitudes. The effect on audible noise from altitudes was analyzed in…
This paper reports an experimental study on deterioration mechanism of concrete suffered quickly freeze-thaw and eroded by 3% sodium chloride and 5% sodium sulfate mixed liquid.The hydration product and microstructure of concrete specimen were tested and analyzed by XRD(X radial diffraction)and SEM(scanning electron m…
Article Rainbows in Channeling of 1 GeV Protons in a Bent Very Short (11,9) Single-wall Carbon Nanotube was published on December 1, 2010 in the journal International Journal of Nonlinear Sciences and Numerical Simulation (volume 11, issue 12).
An analysis was conducted to evaluate the impact of the broad field of severe plastic deformation, ultrafine-grained materials and nanostructured materials on modern Materials Science. Although this research area was first introduced only two decades ago, citation data are used for major journals in Materials Science…
In this work, a simple and easily available method for the synthesis of MgO particles was introduced and the destroying of the stimulants of chemical warfare agents (CWA) (malathion as VX simulant and DMMP as GB stimulant), by synthesized MgO particles (MS284) was investigated. The specific surface area (SSA) of the s…
This study presents an explanation of the stochastic character of dynamic thread loads in the knitting zone of weft-knitting machines based on a probabilistic model of the knitting process in which thread has been treated as a body of heterogeneous viscoelastic properties. Computer simulations were carried out accordi…
The performance of ceramic anodes doped with copper and antimony oxides was examined in cryolite alumina melts under anodic polarization at different cryolite ratios, temperatures, times, and current densities. The corroded part consists of a narrow strong corrosion zone at the anode surface with damage of the intergr…
Transformation behavior in Ti-(50-x)Pd-xFe shape memory alloys has been investigated by electrical resistivity, magnetic susceptibility and specific heat measurements. The alloys with x=14, 16 and 18 exhibit an obvious first order martensitic transformation, but the alloys with x=19, 20 and 22 exhibit no first order t…
We present here structural models for three distinct crystalline polyamic acids which are potential precursors to polyimide networks. In each case, the two different isomeric forms are considered.
Physico-chemical and dispersive characterisation of magnesium oxides precipitated from the Mg(NO 3 ) 2 and MgSO 4 solutions An attempt was made to synthesise magnesium oxide of a high degree of dispersion permitting its use as adsorbent or catalyst. The synthesis method proposed was precipitation with the use of magne…
The microtexture of differently prepared Ba-hexaferrite samples is investigated by means of electron backscatter diffraction (EBSD). Kikuchi patterns are obtained with a high image quality, enabling a spatial resolution of the EBSD maps of about 20 nm. The spatially highly resolved EBSD mappings provide additional inf…
