The electrical and magnetic properties of slightly Cu-deficient BiOCu(0.94)S are investigated using neutron diffraction, ac magnetic susceptibility, magnetization and electrical resistivity measurements. The Cu spins order in a ferromagnetic arrangement below T(C) = 250 K. An antiferromagnetic component develops below…
Biodegradable segmented polyurethanes were prepared with poly(caprolactone) diol as a soft segment, 4,4'-methylene bis(cyclohexyl isocyanate) (HMDI) and either butanediol or dithioerythritol as chain extenders. Platelet adhesion was similar in all segmented polyurethanes studied and not different from Tecoflex® althou…
In our previous report (Takagaki et al 2011 Semicond. Sci. Technol. 26 085031), we have demonstrated that the Bi atoms in Bi 2 Se 3 are substituted by the substrate atoms when its growth is attempted on the surface of transition metals using the hot-wall-epitaxy method. Here, we show that the substitution takes place…
This study presents a novel composite right/left-handed transmission line (CRLH TL) unit cell with high time-delay (TD) efficiency for the design of true-time-delay lines (TTDLs). Shorter inter-digital fingers are used in a symmetrical CRLH TL unit cell to reduce the size by 58% and form a compact CRLH TL unit cell. T…
The mixed Cu and Zn oxide (Cu/ZnO) nanoparticles have been synthesized using Brassica juncea L. plants. The synthesized Cu/ZnO nanoparticles were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and energy dispersive spectrum (EDS). It was found that the synthesized Cu/ZnO nanoparticles…
The c-Fos-c-Jun complex forms the activator protein 1 transcription factor, a therapeutic target in the treatment of cancer. Various synthetic peptides have been designed to try to selectively disrupt the interaction between c-Fos and c-Jun at its leucine zipper domain. To evaluate the binding affinity between these s…
The effects of time and stress state on fracture behaviors and mechanisms of polyvinyl chloride foam have been evaluated by varying displacement rates (0.1 to 1000 mm/min) and specimen thicknesses (5 to 37.5 mm). For thin specimens, the crack tips were under plane-stress condition at all displacement rates. The excess…
Highly aqueously dispersible (soluble) TiO2 nanoparticles are usually synthesized by a solution-based sol-gel (solvolysis/condensation) process, and no direct precipitation of titania has been reported. This paper proposes a new approach to synthesize stable TiO2 nanoparticles by a non-solvolytic method - direct liqui…
The layer-by-layer (LbL) assembly of polyelectrolyte pairs on temperature and pH-sensitive cross-linked poly(N-isopropylacrylamide)-co-(methacrylic acid), poly(NIPAAm-co-MAA), microgels enabled a fine-tuning of the gel swelling and responsive behavior according to the mobility of the assembled polyelectrolyte (PE) pai…

Graft copolymers with various combinations of backbones and branch chains were synthesized using a new vinyl monomer containing an acetal pendant group in conjunction with a combination of metal halides by selective living cationic polymerization without any functional group transformations.
We synthesized a loosely packed submicrometer silica-sphere (LPSS) monolayer at room temperature and used the LPSS monolayer as the frontside light-trapping structure for n-i-p-type amorphous Si (a-Si) solar cells (SCs) to improve photovoltaic characteristics of the cells. The frontside LPSS monolayer plays a role as…
Abstract When forming unipolar resistance switching in material systems, fatal damage often occurs to the top electrodes of Pt/SrTiO x /Pt, Pt/TiO y /Pt and Pt/NiO z /Pt cells. To develop a means of overcoming this problem, we systematically investigated the forming process by applying triangular- and pulse-waveform v…
To evaluate the effectiveness of multielement extraction of Mehlich 1 and Mehlich 3 solutions in soils from southern Brazil, correlation studies are needed. The amounts of phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), copper (Cu), and zinc (Zn) extracted with Mehlich 1 solution, 1.0 M potassium chloride…
Actinic mask defect inspection and metrology requires high-brightness extreme-ultraviolet (EUV) sources. The self-absorption of radiation limits the in-band EUV radiance of the source plasma and makes it difficult to attain the necessary brightness and power from a conventional single unit EUV source. One possible sol…
In this paper we describe the synthesis and characterization of three new complexes of the 1,8-bis(3,5-dimethyl-1 H -pyrazol-1-yl)-3,6-dioxaoctane ligand ( L ) with Zn II ( 1A ), Cd II ( 2A ), and Hg II ( 3A ) ions. The aim of the present study is to investigate the structural effect of the counteranion (Cl – vs ClO 4…
OBJECTIVES: To study the efficacy of an effective anodized titanium surface with enhanced attachment of endothelial progenitor cell (EPC). BACKGROUND: In-stent restenosis is a major obstacle for vascular patency after catheter-based intravascular interventions. Recently, stents that capture EPCs have been paid attenti…
Frequency dependence of dielectric response of HfTaO x -based metal–insulator–metal (MIM) capacitors (sandwich structure; with dielectric layer of different thickness) fabricated with Pt as top and bottom electrodes has been reported. A high capacitance density of ∼8.3 fF µm −2 (at 1 kHz) and a dielectric constant of…
Welcome to the first of what I hope will be a series of Symposia Issues of Philosophical Magazine B . The title of this issue and the topic of the Symposium we have assembled is: “Design, discover...
We have developed a soft actuator using an ionic polymer-metal composite (IPMC) composed of gold electrodes deposited using vacuum evaporation. In comparison with the conventional plating deposition, the vacuum evaporation both is a simple fabrication process and is environmentally friendly. We observe how the gold el…
