The double switching loop has been studied by many groups during the last decade because of its scientific interest. Recently, double switching behaviour was found in the in-plane hysteresis loops of Fe 3 Pt/MgO film. In this paper, the applied field angle dependence of hysteresis loops is studied based on the domain…
The effects of ultrasonic oscillations on extrusion processing, phase morphology, and compatibility as well as mechanical properties for blends of propylene based plastomer (DP) and ethylene/1-octene copolymer (EOC) were examined. The results show that introduction of ultrasonic oscillations into polymer melts in extr…
Abstract Nonisothermal crystallization behavior and crystal morphology of poly(trimethylene terephthalate) (PTT) composites filled with modified nano‐calcium carbonate (CaCO 3 ) had been investigated by using differential scanning calorimetry and polarized optical microscopy. The modified Avrami equation and Ozawa the…
Studies were conducted in the vicinity of a gold processing plant at Tarkwa (Western Region, Ghana) to obtain baseline radioactivity data prior to the installation of Cs-137 nuclear density gauges for quality control measure-ment of the density of slurry in the pipelines at the plant. A survey meter, gamma spectrometr…
The goal of this study was to investigate the use of old newsprint (ONP) fiber as raw material for laboratory made medium density fiberboard (MDF). Effect of ONP fiber mixed with virgin aspen (Populus deltoides) fiber and the press time (3, 4, and 5 min) on the properties of MDF panels were determined. Panels were pro…
An ester (PBPOSS) of 1-pyrenebutyric acid (PBA) and 1-(2,3-propanediol)propoxy-3,5,7,9,11,13,15-isobutylpentacyclo-[9.5.1.1(3,9).1(5,15).1(7,13)]octasiloxane (a polyhedral oligomeric silsesquioxane, POSS) is synthesized by simple one-step esterification. Thin films of PBPOSS fabricated by the spin-coating technique ex…
Malen nach Zahlen: Das Nutzen der Interpartikeldiffusion und des Selbstfokussierens statt des üblichen Fokussierens der Größenverteilung führte zu hochwertigen InAs-Quantenpunkten (QDs) für die Nah-IR-Fluoreszenz (siehe Bild). Die InAs/CdSe-Kern-Schale-QDs wurden mithilfe einer Kombination aus TEM und Elementaranalyse…
The addition of poly(ethylene glycol), PEG, to bioprocessing systems producing polyhydroxyalkanoates (PHAs), has been reported as a means of their molecular weight control and can also support bioPEGylation, resulting in hybrids with amphiphillic properties. However, the study of such natural-synthetic hybrids of PHA-…
The natural fiber composites can be very cost-effective materials, especially for the building and construction industry (e.g., panels, false ceilings, partition boards, etc.), packaging, automobile, and storage devices, etc. They can also be a potential candidate for partial replacement of high cost glass/Kevlar fibe…
Purpose The influence of flood conditions upon traditional cob construction is little understood. This paper aims to investigate the ability of cob materials to resist flood situations and documents basic failure mechanisms. This work also seeks to investigate the wettability characteristics of cob materials utilising…
The reaction between Cs 3 [Mo(CN) 8 ]·2H 2 O and MnCl 2 ·4H 2 O gives two new cyano-bridged bimetallic compounds of ([Mn 2 II (H 2 O) 2 (CH 3 COO)][Mo V (CN) 8 ]·2H 2 O) n ( 1 ) and ([Mn 2 II (H 2 O) 3 Cl][Mo V (CN) 8 ]·4H 2 O) n ( 2 ) in different conditions. The magnetic behaviors of these complexes have been invest…
We present far-infrared ellipsometric measurements of polycrystalline samples of the pnictide superconductor $R{\mathrm{FeAsO}}_{0.82}{\mathrm{F}}_{0.18}$ ($R=\mathrm{Nd}$ and Sm). We find evidence that the electronic properties are strongly anisotropic such that the optical spectra are dominated by the weakly conduct…
This paper presents an experimental study on the femtosecond (fs) laser ablation of bundles of single wall carbon nanotubes (SWCNTs) deposited on glass and the resulting nanoablation of glass beneath the bundles. The peak ablation threshold of SWCNT bundles is 50 ± 12 mJ cm −2 , which is about ten times lower than the…
A general least-squares technique for X-ray diffraction line broadening analysis has been developed. The technique can be used to determine single, double, and triple line broadening effects caused by small particle sizes, microstrain, stacking faults, or all three presented in a closed-packed hexagonal nanomaterial.…
We have recently shown that the sound velocity obtained from the inelastic x-ray scattering (IXS) measurement exceeds the ultrasonic wave velocity of a Pd-based metallic glass in a rigid glass state far below its glass transition temperature. Here we report that no obvious evidence of faster processes, which are suppo…
K-feldspars in the system K[AlSi 3 O 8 ]–K[FeSi 3 O 8 ] were synthesized hydrothermally at P H 2 O = 1 kbar and T = 400 °C, 500 °C, and 600 °C to investigate their ordering behaviour, the extent of Al, Fe substitution, and the influence of oxygen fugacities on the run products (Ni–NiO compared to Cu–Cu 2 O buffer cond…
Based on surface plasmon resonant enhancement, a method to realize photolithography beyond diffraction limit by using polystyrene spheres (PSs) self-assembled on silver slab was proposed in this paper. The optimum parameters for PS with different diameters were presented. In order to verify this method, numerical simu…
The magnetic susceptibility of NdCo1 − x Ga x O3 (x = 0, 0.1, 0.3, 0.5, 0.7, 0.8, 0.9, 1) has been measured at temperatures from 80 to 950 K. The effective magnetic moments (μeff) due to the magnetic moments of the Co3+ and Nd3+ ions have been determined in the temperature ranges of Curie-Weiss behavior, 130–370 and 6…
Magnetisches Netzwerk: Ein 2:1-System aus [Ru2II,IIL4]-Schaufelradkomplexen und BDTA-TCNQ ergibt einen neuen Strukturtyp von Elektronentransfersystemen mit einem dreidimensionalen Netzwerk. Die Struktur zeigt einen langreichweitigen ferromagnetischen Übergang bei Tc=107 K (siehe χ-T-Kurve und Blick entlang der a-Achse…
Microbatch crystallization under oil is a powerful procedure for obtaining protein crystals. Using this method, aqueous protein solutions are dispensed under liquid oil, and water evaporates through the layer of oil, with a concomitant increase in the concentrations of both protein and precipitant until the nucleation…
