Abstract The superior association of the inherent good mechanical and electrical properties makes carbon nanotubes (CNT) exceptionally interesting for the production of composite fibers of thermoplastic polymers with CNT. Alignment of the CNT in the polymer fiber is important for improved mechanical properties. Especi…
Shock-wave experiments are performed with four different kinds of glasses of different hardness compressed at different levels. The experiments with the glass specimens consisting of layered thin plates confirm the appearance of a failure wave in elastically compressed soda lime glass, heavy flint glass, K8 crown glas…
Polymer insulating materials are required for use in high altitude regions. For the use of polymer insulating materials in such regions, it must be confirmed whether the resistance to tracking at high altitudes is different from that at altitudes near the sea level. In this paper, an artificial atmospheric chamber was…
Using pulsed laser deposition (PLD), coaxial coating of carbon nanotubes (CNTs) with various inorganic materials (e.g., ZrOx,HfOx,AlOx,ZnOx, and Au) has been performed. The morphology and crystallinity of the coated layers were found to differ according to the materials used even at the same deposition temperature. Fo…
The self-synthesis of tungsten oxide (W 18 O 49 ) nanowires on sputter-deposited W films prepared under different O 2 /Ar flow rate ratios (OAFRRs) in the sputtering gas is reported. After thermally annealing at 700–850 °C in N 2 ambient for 15 min, dense and well crystalline W 18 O 49 (010) nanowires or nanobelts wer…
A large number of single-crystalline TaS2 nanobelts have been prepared via a two-step method. In this approach, TaS3 nanobelts as precursors were synthesized via chemical vapour transition (CVT), and pyrolysed into TaS2 nanobelts in vacuum. Transmission electron microscopy (TEM) and scanning electron microscopy (SEM)…

Orientation information as obtained by electron back scattering diffraction in crystalline material is conventionally visualised in orientation maps with different colours representing different orientations. The possibility of resolving orientation inhomogeneities from such maps depends strongly on the selected colou…
A series of poly(oxypropylene)diamines D230, D400, D2000, and D4000, having molecular weights of hydrophobic segments of 230, 400, 2000, and 4000, were used as ligands to synthesize self-organized gold nanocrystals. Ligand exchange significantly reduced the average particle size and the polydispersity of nanocrystals,…
A new class of porous, mixed phase titanosilicate materials containing a microporous TS-1 phase and a mesoporous Ti-MCM-48 phase has been successfully synthesized. A novel, one-pot synthesis method was used in which the organic templates for the mesoporous and microporous phases were added sequentially to the same rea…
XPS measurements of poly(acrylic acid) recorded with a SSX-100 spectrometer in standardized experimental conditions are presented: survey scan, high resolution core level spectra as well as the energy loss regions of carbon and oxygen peaks are analyzed. This is part of a contract work aiming to record spectra in the…
XPS measurements of poly(methyl methacrylate) recorded with a SSX-100 spectrometer in standardized experimental conditions are presented: survey scan, high resolution core level spectra as well as the energy loss regions of carbon and oxygen peaks are analyzed. This is part of a contract work aiming to record spectra…
Ceramic BaCe0.8Ho0.2O3−α with orthorhombic perovskite structure was prepared by conventional solid state reaction, and its conductivity and ionic transport number were measured by ac impedance spectroscopy and gas concentration cell methods in the temperature range of 600–1000 °C in wet hydrogen and wet air, respectiv…
We have calculated the band structures of solid pentacene. One of our models makes use of experimental data obtained for a single crystal [R. B. Campbell et al., Acta. Crystallogr. 14, 705 (1961); R. B. Campbell and J. M. Robertson, Acta. Crystallogr. 15, 289 (1962)] and the other one considers a thin film fabricated…
Abstract Clothing for garments is designed to meet both the safety and the comfort of human beings. Porosity is considered to be one of the basic features representing a textile structure. The properties of fabrics were analyzed by determining the efficiency of fabric porosity. The woven fabric multi-layer structure,…
p-Hydroxybenzoate hydroxylase (PHBH) is a homodimeric enzyme in which each subunit noncovalently binds one molecule of FAD in the active site. PHBH is a model system for how flavoenzymes regulate reactions with oxygen. We report single-molecule fluorescence studies of PHBH in the absence of substrate that provide data…
It is well known that doping can greatly affect the ferroelectric properties of Bi4Ti3O12: however, the mechanisms of the doping effect, especially doping at the B site, are not well understood. The effect of B-site doping with different ion sizes and valences on the remanent polarization and fatigue endurance was inv…
The exchange-spring behavior found in Sm–Co (20nm)∕Fe epitaxial bilayer films was investigated by analyzing major hysteresis and recoil curves as a function of anneal conditions. The hard layer consists of nanocrystalline intermetallic Sm–Co hexagonal phases (majority phase Sm2Co7 with SmCo3 and SmCo5). Recoil curves,…
The effect of Co content on the phase formation, structure, and magnetocaloric effect of rapidly quenched La(Fe1−xCox)11.4Si1.6 with x=0 to 0.12 were investigated by x-ray diffractometry and magnetic measurements. Rietveld analyses indicate that with increasing Co content, the amount of the 1:13 phase increases from a…
Abstract A rare example of a mono‐aqua‐bridged copper( II ) dimer,namely [Cu 2 (μ 2 ‐H 2 O)L 2 (H 2 O) 2 ](ClO 4 ) 2 · 2H 2 O ( 1 ), has been synthesised and its structure determined by single‐crystal X‐ray diffraction. Each Cu II centre is in a square‐pyramidal surrounding formed by a Schiff base and a terminal H 2 O…
