Environmentally friendly polyurethane (PU) spray foam insulation was prepared by substituting petrochemical polyol with soy-based polyol. The effects of adding wood fiber and water on the cell morphologies were studied. Cell size increased with the presence of wood fiber, but it decreased with an increase of water (H2…
Purpose The purpose of this paper is to develop textile materials with a pH‐sensitive function. Design/methodology/approach As a start point, the feasibility of incorporating pH‐indicators in conventional textiles using standard dyeing processes was investigated. Next, a pH‐indicator was incorporated into a nylon nano…
OBJECTIVES: Nephrogenic systemic fibrosis occurs in patients with poor renal function who receive gadolinium-based contrast agents (Gd-CAs). Several reports suggest that this is more likely to occur with the less stable forms of Gd chelates, suggesting a release of cytotoxic free Gd ions from these. There is evidence…
Purpose The purpose of this paper is to examine the effects of coating process parameters (base fabric, coating material, coating technique and production parameters) on mechanical properties of coated fabrics. Design/methodology/approach In this research, 24 coated fabrics were produced under controlled production co…

The oxygen exchange kinetics of platinum on yttria-stabilized zirconia (YSZ) was investigated by means of geometrically well-defined Pt microelectrodes. By variation of electrode size and temperature it was possible to separate two temperature regimes with different geometry dependencies of the polarization resistance…
Carbon nanostructures have been widely studied due to their unique properties and potential use in various applications. Of interest has been the study of carbonaceous material with helical morphologies, due to their unique chemical, mechanical, electrical and field emission properties. As such it is envisaged that th…
Glasses are known to exhibit quantitative universalities at low temperatures, the most striking of which is the ultrasonic attenuation coefficient 1/Q. In this work we develop a theory of coupled generic blocks with a certain randomness property to show that universality emerges essentially due to the interactions bet…
Solidification of 4He confined in a one-dimensional 2.8-nm channel of FSM was studied by pressure and heat capacity measurements. It was found that the freezing pressure in the channel is greatly elevated and is between 3.3 and 3.8 MPa at absolute zero. Furthermore, the density change at the liquid-solid transition is…
We theoretically investigate dynamics of the magnon wavepacket, by constructing the semiclassical equation of motion of the magnon wavepacket in insulating ferromagnets and utilizing an analogy of the electron systems. The magnon wavepacket undergoes two types of orbital motions: a self-rotation motion and a motion al…
常磁性対破壊効果の強い第二種超伝導体において、重心運動量が0ではないCooper対による、Fulde-Ferrell-Larkin-Ovchinnikov状態(FFLO状態)と呼ばれる超伝導状態が理論的に予想され、近年、重い電子系超伝導体や有機物超伝導体において、その実現が示唆される実験結果が得られている。この論文では、超伝導理論の基礎をひと通り学習した学生を想定して、FFLO状態について入門的な解説をする。(より詳しいレビューとしては、文献[1,2,3]などがある。)
Effect of polymer concentration and composition on the electro-optic properties of blue phase liquid crystal (BPLC) composites is investigated. By increasing the polymer concentration, a more stable structure and faster response time are obtained, while keeping a low hysteresis (∼3%). The major tradeoff is the increas…

The formation of nano-sized alumina-titanium carbide (Al2O 3-TiC) composite powders from aluminum, graphite and nano-sized anatase titania powder compact were directly synthesized by electro-plasma process (EPP) and the following combustion reaction. The theoretical density of compact played an important role for the…
Computational fluid dynamic has already become a widely used and indispensable design and optimization tool in many technical areas. In the present work, the CFD simulations have been coupled with complex chemical reactions to model a membrane tubular reactor which is used to produce phenol from benzene in the vapor p…

We study network loss tomography based on observing average loss rates over a\nset of paths forming a tree -- a severely underdetermined linear problem for\nthe unknown link loss probabilities. We examine in detail the role of sparsity\nas a regularising principle, pointing out that the problem is technically\ndistinc…
Abstract — A molecular algorithm is a set of molecular interactions that carry out a particular task. We describe a molecular algorithm for self-assembling a path between two stationary points when the locations of these points are not known in advance. While efficient path finding algorithms for electronic robots exi…
Roughly, the multivariate methods in this chapter deal with situations where two or more outcome variables are of interest. In the context of regression, for example, a goal might be to estimate simultaneously the typical cholesterol and the typical triglyceride level given that an individual is 20 pounds over his or…
