We review our research on properties of two important functional materials in which dynamics plays an essential role, namely, fast‐ion conductors and negative thermal expansion materials. We bring out the underlying role of the lattice dynamics in terms of the soft phonon modes in both cases. Then, using molecular dyn…
The flyweight of powder metallurgy is a complex structure part of VE distribution pump. The components of the powder forming process often contain the defects such as instability of the quality, over tolerance of the size accuracy, and disqualification of the appearance. By analyzing the causes of defects and correspo…
CuO nanoparticles of 80 nm were successfully prepared by solution method. X-ray diffraction and scanning electron microscopy were used to characterize the phase formation and microstructure of the CuO powder and ceramics, respectively. CuO ceramics were obtained by sintering the CuO nanocrystalline powder at 900 (PR-9…
We have prepared ZnO nanostructures using electrodeposition method for different precursors and deposition conditions. Very wide range of morphologies of ZnO nanostructures could be obtained by using this simple and inexpensive solution based growth method.
We report on the fabrication of heterojunction solar cells based on copper (I) oxide (p‐Cu2O) cathodically electrodeposited onto transparent conducting thin (TCO) films of zinc oxide (n‐ZnO). The TCO films have been grown by low temperature electrodepositions in aques solution onto conductive SnO2‐coated glass substra…
Thermal degradation of poly(alkyl methacrylates) and polyurethane pressure-sensitive adhesives Gas chromatography, coupled with the temperature controlled pyrolysis technique, can be used as a quick method of identification of polymers such as acrylates, methacrylates and polyurethanes. Polymers based on alkyl methacr…
We have developed a scattering-type scanning near-field optical microscope with a charge sensitive infrared phototransistor. Near-field images of spontaneously emitted thermal radiation were clearly obtained and the spatial resolution was better than 300 nm.
This article presents the overall methodology and the results of the three-dimensional (3D) finite element buckling analysis of the primary containment drywell shell at the Oyster Creek Nuclear Generating Station (Oyster Creek). The buckling stresses, eigenvalues, and eigenvectors are computed using ANSYS finite eleme…

Systematic measurements of the temperature dependence of the two-body collision-induced loss of dark paraexcitons in Cu2O show a diverging cross section at low temperatures. Scattering problems between excitons in general require quantum-mechanical treatments.
In this paper, strain gradient thermo-elasticity formulation for Functionally Graded (FG) thick-walled cylinders is presented. Elastic strain energy density function is considered to be a function of gradient of strain tensor in addition to the strain tensor. The material properties are assumed to vary according to po…
PWR fuel assembly (FA) experiences many changes from the time it is manufactured, loaded in the reactor and removed from the reactor for reprocessing or stroage etc. Any of these alterations which impact spent nuclear fuel (SNF) integrity should be considered to design a cask/canister. Regarding the cask/canister desi…
The metal-wire based metamaterial is found to be able to reflect TM-polarized light with a higher efficiency compared to plain metal. The prospect of such medium for designing a hollow-core infrared fiber is investigated.

This is a correction to the author's article [Multiscale Model. Simul., 8 (2010), pp. 1562–1580].
Technology of periodic microstructures formation on plastic plate, the polyethylene terephthalate (PET) plate, was developed with an aerosol beam. The beam was composed of submicron-size anatase titania (TiO2) particles. Formation mechanism depended on an incident angle of the beam to the PET plate. At an incident ang…
We report an experimental and theoretical investigation of Ramsey-type spectroscopy with high-order harmonic generation applied to autoionizing states of Krypton. The ionization yield, detected by an ion-mass spectrometer, shows the characteristic quantum interference pattern. The behaviour of the fringe contrast was…
In this note, an exact solution is presented for the flow produced by a plate oscillating with arbitrary periodic oscillation in a porous medium. The velocity field is composed of a steady state part and a transient part. It is found that the flow depends on the permeability parameter. The velocity profiles and the wa…

Si-nanocrystal incorporated Si-rich SiOx strip-loaded waveguide amplifiers grown by detuning N2O/SiH4 fluence ratio and RF power are demonstrated with blue, yellow, and red multi-color amplified-spontaneous-emission and gain coefficients of 160, 70 and 45 cm−1.
