To demonstrate the potential for microelectromechanical systems, nanotube beams composed from self-assembled closely packed and aligned single-walled carbon nanotubes were fabricated and their mechanical properties were measured. We found that the nanotube beams behave as a cohesive, rigid, and elastic body with a sou…
Abstract In this study, transglutaminase (TGase)‐mediated crosslinking of gelatin on the surface of wool and its effect on the properties of wool fabric were investigated. For the wool fabric used in this study, gelatin (3 g/L) treatment for 1 h combined with 20 U/g of fabric microbial TGase reduced the area shrinkage…
Austenitic oxide-dispersion-strengthened (ODS) stainless steel was fabricated using a wet mixing process without a mechanical milling in order to reduce contaminations of impurities during their fabrication process. Solution of yttrium nitrate was dried after a wet mixing with 316L stainless steel powder. Carbon and o…
Abstract Poly( L,D ‐lactide) [P( L,D )LA], LL/D ratio 96/4, and poly( L,DL ‐lactide) [P( L,DL )LA], L/DL ratio 70/30, multifilament fibers were prepared by wet‐spinning and the effects of the spin draw ratio and the coagulant on the morphological, thermal, and mechanical properties of the filaments were studied. The h…
Self-assembly methods for the immobilisation or encapsulation of the positively charged redox protein, cytochrome c (cyt c), in layered organoclays or silica nanoparticles, respectively, are described and contrasted. Protein-polymer-organoclay nanocomposites are produced by spontaneous restacking of delaminated aminop…
Abstract A poly(urethane‐imide) diacid (PUI), a diimide‐diacid with a soft structure unit, was directly synthesized from the reaction of trimellitic anhydride and isocyanate terminated polyurethane prepolymer. FT‐IR and NMR were used to characterize its chemical structure. Then PUI was blended with two types of epoxy…
Abstract The mechanical properties of Bombyx mori silk yarns and baves were investigated with tensile testing method. After silk yarns were pre‐extended at different strain levels and fixed for a while followed by recovery process, the tensile characteristics were examined in detail. It was commonly observed that low…
The ability to make inorganic nanocrystals of controlled size, shape, and composition is well-established for some elements and compounds, but by no means has been generalized to the entire periodic table. A new paper in this issue of ACS Nano offers a route to explore more of the periodic table with increased control…
The magnetocaloric effect (MCE) of the compound ${\text{Er}}_{5}{\text{Si}}_{4}$ has been investigated as a function of the applied magnetic field (up to 50 kOe) and the hydrostatic pressure (from ambient pressure up to 9 kbar). At constant magnetic field change, increasing the pressure up to 1.4 kbar induces a global…
This paper presents the design, fabrication, numerical simulation, and experimental validation of a micromachined probe that measures thermal conductivity of biological tissues. The probe consists of a pair of resistive line heating elements and resistance temperature detector sensors, which were fabricated by using p…
The key concern for transformers experiencing ferroresonance is whether the energy transferred into the transformer body during core saturation by the nonsinusoidal currents is damaging. Saturation and the consequent incompetency of the core to contain the flux manifests itself as current induced in parts of the trans…
Abstract High‐solids, low‐viscosity, stable polyacrylamide (PAM) aqueous dispersions were prepared by dispersion polymerization of acrylamide in aqueous solution of ammonium sulfate (AS) using poly (sodium acrylic acid) (PAANa) as the stabilizer, ammonium persulfate (APS) or 2,2′‐Azobis ( N , N ′‐dimethyleneisobutyram…
Abstract Bamboo, a lignocellulosic material, is a renewable source of interest as feedstock for production of cellulose derivatives by chemical functionalization. Optimization of hydroxypropylation of cellulosic material (average DP 816), isolated from bamboo ( Dendrocalamus strictus ) was, therefore, performed with r…
Thermally stable cubic silver nanoparticles were grown by simply annealing a silver nano-thickness layer on a crystalline TiN buffer layer deposited on a Si(1 0 0) substrate. Formation of silver nanocubes was investigated by scanning electron microscopy, atomic force microscopy, x-ray diffractometry and UV–visible spe…
Simulation and optimization tools are commonly used in the design phase of advanced electronics devices. In this work, we present a thermal simulation and design optimization tool for infrared thermopile detectors based on a closed membrane structure. The tool can be used to simulate and optimize thermopile detectors…
In this paper, a novel method for the compensation of commercial current transformers (CTs), based on the insertion of a series analog circuit at the secondary winding is proposed. The method allows the enhancement of existing transformers which can, thus, reach the 0.2 ratio error and a phase error lower than the mea…
We have investigated two-step growth of high-quality epitaxial ZnO films, where the first layer—the buffer layer (nucleation layer template)—is grown at a low temperature (230–290 °C) to induce a smooth (two-dimensional) growth. This is followed by growth at a moderate temperature ∼430 °C to form high-quality smooth Z…
Abstract Einheitliche Nanoringe: Stabile toroidale Micellen mit sehr einheitlicher Form und Größe bilden sich spontan aus einem selektiven THF/Ethanol‐Lösungsmittelgemisch (siehe 3D‐AFM‐Bild). Die Donut‐förmigen Micellen können als Template für das Wachsen von Goldnanopartikeln dienen, die sich entlang der Ringoberflä…
Abstract The thermal decomposition of organophosphorus fire‐retardant (OP1311) and/ or organonanoclay (Cloisite 30B) is hereby investigated employing thermogravimetric analysis (TGA), to give an insight into their intrinsic behaviour and interaction in polymer nanocomposites for fire safety applications, because the a…
At JAEA, a test blanket module (TBM) with a water-cooled solid breeder is being developed. This paper presents recent achievements of research activities for the TBM, particularly addressing the pebble bed of the tritium breeder materials and tritium behaviour. For the breeder material, the chemical stability of Li 2…
