In order to clarify the influence of precipitated hydride on the fracture behavior of Zircaloy cladding tubes, the stress-strain distribution of the cladding was estimated by finite element method (FEM) analysis. The mechanical properties of α-phase of zirconium and zirconium hydride required for the analysis were exa…

Individual carbon nanotubes (CNTs) have been located and investigated using scanning confocal Raman microscopy. In particular, the geometry of thin bundles and individual single-walled CNTs was able to be examined by combining Raman with scanning force microscopy. Spatially resolved Raman spectroscopy could thus be pe…

A pronounced difference in the behavior of heteroarm star copolymers from the conventional diblock copolymers is analyzed theoretically and experimentally on the example of symmetric polystyrene-poly(2-vinylpyridine) (PS 6 P2VP 6 ) star block copolymer melts. Microphase separation of PS 6 P2VP 6 stars with volume frac…

Photoluminescence (PL) and Raman spectra of silicon nanocrystals prepared by Si ion implantion into SiO2 layers on Si substrate have been measured at room temperature. Their dependence on annealing temperature was investigated in detail. The PL peaks observed in the as-implanted sample originate from the defects in Si…

Photochemical reaction of n -dodecanethiol-derivatized silver nanoclusters dispersed in cyclohexane has been studied in the picosecond−second time range and has been found to depend nonlinearly on the irradiance of photolysis light. The static absorption bleach by excitation at 532 and 355 nm increases with the irradi…

We have investigated relaxation dynamics of lithium ions in lead bismuthate glasses in the frequency range from 10 Hz to 2 MHz and in the temperature range from 303--553 K. Using the Anderson-Stuart model, we have calculated the activation energy, which is observed to be lower than that of the dc conductivity. We have…

Abstract Supercritical carbon dioxide (scCO 2 ) was added during compounding of polystyrene and poly(methyl methacrylate) (PMMA) and the resulting morphology development was observed. The compounding took place in a twin screw extruder and a high‐pressure batch mixer. Viscosity reduction of PMMA and polystyrene were m…

Diamond-like carbon (DLC) films have received much attention recently owing to their properties, which are similar to diamond: hardness, thermal conductivity, corrosion resistance against chemicals, abrasion resistance, good biocompatibility, and uniform flat surface. Furthermore, DLC films can be deposited easily on…

Specific information extracted from low-frequency Raman data, for a widely varied in chemical nature class of inorganic glass formers, are presented showing the weakness of the basis on which relevant current models and phenomenological correlations rely. The three pertinent issues of the field, namely, relaxation to…

Precise resonant experiments on ${\mathrm{Fe}}_{8}$ magnetic clusters have been conducted down to 1.2 K at various tranverse magnetic fields, using a cylindrical resonator cavity with 40 different frequencies between 37 and 110 GHz. All the observed resonances for both single crystal and oriented powder have been fitt…

High-energetic particle irradiation of carbon structures containing a graphite-diamond interface can lead to low-pressure diamond growth. A theoretical model predicting irradiation-induced diamond growth has been presented in a previous paper [Zaiser and Banhart, Phys. Rev. Lett. 79, 3680 (1997)]. In the present study…

Gene therapy has yet to achieve reproducible clinical efficacy, due to inadequate gene delivery, inadequate gene expression, or dose-limiting toxicity. We have developed a gene therapy technology for tissue repair and regeneration that employs a structural matrix for DNA delivery. The matrix holds the DNA vector at th…

Abstract The decomposition of dichloromethane (CH2Cl2) in model air gases (concentration, around 100 ppm) by electron beam (EB) and γ-ray irradiation was studied using batch-type glass reactors of 500 ml volume. The addition effect of water on the decomposition was also investigated. In dry air, one-pass EB irradiatio…
