A relationship between the electric resistance of single-crystal homoepitaxial and polycrystalline diamond films and their internal structure has been investigated. It is established that the electrical conductivity of undoped homoepitaxial and polycrystalline diamond films is directly related to the dislocation densi…
A new signal quality metric and novel margin allocation technique for a page based holographic memory system were developed. The margin allocation result for a 500 GB capacity system is both realistic and achievable.
The local environment of Pb impurity atoms in BaTiO 3 , SrTiO 3 , and CaTiO 3 crystals was studied by XAFS technique. It is shown that, in both polar and nonpolar phases of BaTiO 3 and in SrTiO 3 , the Pb atoms are displaced from the A lattice sites by ∼0.15 Å; in CaTiO 3 this displacement is absent. Large values of D…
The mode I critical strain energy release rates, G IC , of two polymer matrix composites were experimentally measured at temperatures ranging from -196°C to 160°C. The two composite materials investigated in this study were IM7/PETI-5 and IM7/977-2. Double cantilever beam specimens were manufactured with a °[0° 7 / ±…
The structures of thin films of the polystyrene-polybutadiene-polystyrene (SBS) and polystyrene-poly(methyl acrylate)-polystyrene (SMAS) triblock copolymers were studied. The film morphology was found to depend on the conditions of film formation. The average domain sizes of these films and the period of the lamellar…
Measurement of Refractive Index, Specific Heat Capacity, and Thermal Conductivity for Ag6.0In4.5Sb60.8Te28.7 at High Temperature, Kuwahara, Masashi, Suzuki, Osamu, Tsutsumi, Kouichi, Yagi, Takashi, Taketoshi, Naoyuki, Kato, Hideyuki, Simpson, Robert E, Suzuki, Michio, Tominaga, Junji, Baba, Tetsuya
Abstract The synthesis and solution and thin‐film characterization of eight octasubstituted dendritic phthalocyanines (Pcs) and their zinc complexes are reported. The Pc chromophore was substituted in the 2,3,9,10,16,17,23,24‐positions with three generations of benzylaryl ether dendrons with either a benzyl ( 3a‐3c )…
After a noticed introduction of the ldquonanodielectricrdquo concept in 2001, some of the innovative and original elements of the concept are revisited. Although the presence of nanometric objects and the existence of processes with characteristic lengths comprised in the nanoscale existed, the exacerbation of these i…
Recent developments in the field of manufacturing techniques and alloy development of light materials are reviewed. In the field of manufacturing Aluminium based components, special attention is given to casting, including liquid forging and semi-solid forming technology while for sheet metal forming technology the fo…
We have studied the thermoelectric properties of quantum dot (QD) chain nanocomposites in which the QDs are aligned to form chains. In both the InAs/GaAs and Ge/Si systems, we use a constant relaxation time approximation to calculate and compare the electrical conductivity, Seebeck coefficient, and thermoelectric powe…
Three-dimensional (3-D) computed micro X-ray tomography (micro CT) and 3-D confocal micro X-ray fluorescence (MXRF) combined are very useful nondestructive metrology techniques for determining the unique compositional and morphological information of fusion targets and target materials. Micro CT and confocal MXRF are…
On-line continuous partial discharge measurements of medium voltage substations have not attracted the same attention in the electrical community as compared to similar PD measurements of rotating machines. The cost of an unexpected outage however may be considerably more significant of a main distribution bus than ju…
The finite element method has been employed to study the effects of different boundary conditions on the axial buckling of multiwall carbon nanotubes (MWCNTs). Unlike previous works, both homogeneous and heterogeneous end constraints are considered for the constituent tubes of various MWCNTs comprising shell-type (i.e…
Abstract This overview covers the most relevant results obtained by our group in the last few years concerning the synthesis and catalytic applications of metal complexes anchored to the surface of carbosilane dendrimers functionalized with iminopyridine ligands. Nickel dibromide complexes activated with methylalumino…
Behavior of lithium peroxide samples at heating in air was studied by the methods of thermogravimetric analysis (TGA) and differential thermal analysis (DTA). In the temperature range from 32 to 82°C all the studied samples we found to react with water vapor forming lithium peroxide monohydrate as confirmed by the met…
For modern automotive applications, after-treatment systems have become essential to respect the new emission standards. All the automotive world's attention is focused on catalysis systems because they seem to be one of the best ways to reach the future standards. As a result, after-treatment issues are more and more…
This paper is focused on the preparation and characterization of glutathione (GSH) coated near infrared quantum dots (QDs). The preparation method is based on surface modification of hydrophobic core/shell CdSeTe/CdS by glutathione, which makes the QDs water-soluble. Moreover, tripeptide GSH provides a biocompatible b…
A nickel-containing shungite powder has been synthesized by means of chemical reduction from aqueous solutions. The chemical composition and radio-absorbing properties of this powder have been studied.
An oil droplet is placed on an oil bath at least ten times more viscous. When the oil bath is vertically shaken according to a sinusoidal motion, the droplet may bounce indefinitely on the bath. This sustained bouncing mode is stable when the forcing acceleration is higher than a threshold value. On the other hand, th…
Abstract Oriented architectures are formed on nanocrystals with incorporation of organic polymers through a biomimetic route. The composites of potassium sulfate and potassium hydrogen phthalate/poly(acrylic acid) exhibit a mosaic structure consisting of organic polymers and ca. 20 nm nanocrystals. These nanocrystalli…
