In this study, plane-strain elastoplastic finite element model is developed to predict the residual stress in the surface layer of ultrasonic surface rolled material. During ultrasonic surface rolling process elastoplastic loading by a mass of high energy successive impacts is exerted in a small zone of the surface. A…
The spectroscopic properties of the FT-IR and FT-Raman spectra of the 2-[(2,3-dimethylphenyl)amino]benzoic acid (DMPABA) compound have been recorded in the region 4 000～400 cm-1. The molecular structure, vibrational wavenumbers were calculated using DFT (B3LYP) method with 6-31G(d,p) and 6-311++G(d,p) basis sets. The…
Variants of liquid-crystal spatial light modulators control devices, that provide partial or fully parallel information input in multichannel optical signal processing systems are suggested. Applications of the proposed solutions enables to increase to a considerable extent the optical processors capacity that is actu…
Compact high density electronic equipment is achieved using the stacked via technology in a build-up substrate. In order to design the build-up substrate, the impact of the viscoelasticity behavior of insulating resin under heating and cooling must be considered. This paper investigates how to predict the stacked via…
A numerical-analytical method of reconstructing complex frequency-dependent permittivities is proposed. Measurements of the transmission coefficient for three typical metamaterial antenna units are performed and the frequency-dependent effective complex permittivity of the units is reconstructed in a wide frequency ra…
We demonstrate experimentally and numerically that a bilayer triangular-shaped chiral metamaterial (TCMM) gives a nearly perfect cross-polarization with 90% polarization conversion efficiency reported at X-band regime. The giant optical activity in the proposed TCMM arises due to the strong cross-coupling between the…
Chopped bamboo-reinforced epoxy composites were fabricated and tested to investigate their tribological properties. Three different weight fractions of 6%, 8% and 10% were used as reinforcement in the composites. Wear behaviour of composites was investigated by pin on disc wear testing device. To analyse the results t…
The need to improve the technical level of production of construction materials, their product range, to improve product quality and reduce its cost requires the expansion of the raw material base, the use of resource and energy saving technology and design solutions. To implement all these it is necessary to conduct…
We used the spheroidal beam equation to calculate the sound field created by focusing a transducer with a wide aperture angle to obtain the heat deposition, and then we used the Pennes bioheat equation to calculate the temperature field in biological tissue with ribs and to ascertain the effects of rib parameters on t…
Due to their high flexibility, high conductivity and high transparency in a wide spectrum range, metal nanowires and meshes are considered to be two of the most promising candidates to replace the traditional transparent conducting films, such as tin doped indium oxide. In this paper, transparent conducting films made…
In order to enhance catalytic properties of palladium or gold/palladium alloy on polyaniline surface, highly pure PANI nanofibers doped with phosphoric acid were synthesized via chemical self-assembled method. Its general morphology was observed by scanning electron microscopy analysis. The deposition of palladium or…
Double metal amidoborans are considered to the most promising candidates for metal amidoborans. In this paper, the crystal structures, electronic properties, chemical bonds, hydrogen removal energies, and HOMO-LUMO of NaAB, NaLiAB, and NaMgAB have been studied. The GGA corrected density functional theory have been emp…
Using stearic acid as modifier, the surface of mica pearl pigment organic modification technology are discussed in this paper, and the application effect of after modified. X-ray powder diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy and Scanning electron microscope (SEM) were used to characterize t…
The effect of rare earth element Ce addition on the microstructure and martensitic transformation behavior of Ti51Ni49 shape memory alloy was investigated by scanning electronic microscope (SEM), X-ray diffraction (XRD) and differential scanning calorimetry (DSC). The results show that the microstructure of TiNiCe ter…
