The effects of size and shape of calcium carbonate (CC) and hydroxyapatite (HA) fillers on the degradation of poly(DL-lactic acid-co-glycolic acid) (PLGA) were examined in the PLGA composite films containing 50 mass% of the fillers. The composite and unfilled films were prepared by our method reported previously. The…
A university laboratory experiment for the US Department of Energy magnetic fusion research program required a simulant for liquid lithium. The simulant choices were narrowed to liquid gallium and galinstan (Ga-In-Sn) alloy. Safety information on liquid gallium and galinstan were compiled, and the choice was made to u…
Special requirements for microwave mechanics -- Systematic flowchart model -- Material selection for microwave mechanics -- Computer-aided environment for design work -- Instructions for technical documentation and dimensioning -- Effects of production volume and related topics -- Welded components -- Other joining te…
Pseudomonas chlororaphis HS21 was isolated from a soil sample and found to produce medium-chain-length polyhydroxyalkanoates (MCL-PHAs) using palm kernel oil (PKO) as the sole carbon source. Up to 3.3 g/l dry cell weight containing 45% MCL-PHA was produced, when the strain was grown for 21 h in a jar fermentor culture…
The dynamic rheological behavior of polymer composites filled with particles has been an interesting topic in polymer research fields because of the challenging physical problems and the increasing technological applications behind. In this paper, recent progress in studies on the characteristic dynamic rheological re…
The Ti–18Nb–4Sn alloy has been confirmed to possess much higher corrosion resistance compared to the NiTi alloy throughout immersion time up to 604.8 ks in a 0.05 mass% HCl at 310 K open to air. The Ti–18Nb–4Sn alloy shows higher open circuit potential, compared to titanium metal and NiTi alloy. The higher open circui…
Single-crystal X-ray diffraction measurements at low temperature were carried out using the image-plate technique in the vacuum chamber at BL02B1 of SPring-8. The intensity data were collected at 20 K, 70 K, and 150 K, 36 photographs being taken at each temperature. The systematic extinctions observed at 20 K could be…
The thermal contact resistance of polymer-based carbon fiber composites was calculated from experimental thermal conductivity values. Thermal conductivity of the composites increases as the fiber content increases. In order to explain the variation with size and volume fraction of the conductive inclusions in the comp…
Rice hulls and crushed pecan shells are two solid waste materials with potential for use as thermal insulation. The apparent thermal conductivity, ka, of parboiled rice hulls and crushed pecan shells has been measured in two laboratories over the temperature range 4 to 41 oC using heat-flow meter apparatuses. Thermal…
In a preliminary calculation the simple case of parallel flow past flat plates is investigated. Using this simplification numerous fouling experiments under different conditions were performed. The measurements were taken using aqueous solutions of CaSO4 and serve for the verification of the numerical simulation. The…
This paper is in four parts. The first is related to general considerations and experimental analyses, and each of the others is related to different approaches to theoretical analyses of the mechanical behaviour of weft-knitted fabrics and weft-knitted reinforced composites made of glass fibre. The objective is to fi…
Many organisms from a wide variety of taxa produce amorphous calcium carbonate (ACC), despite the fact that it is inherently unstable and relatively soluble in its pure state. These properties also make it difficult to detect and characterize ACC. Raman spectroscopy is a particularly useful method for investigating AC…
The complex role of sulfur in magnesium treated iron was evaluated in both ductile and compacted graphite irons. At elevated levels, sulfur can act as a harmful element resulting in magnesium-neutralization and increased dross formation but is also beneficial and essential at lower levels because it promotes suitable…
Cure characteristics and mechanical properties of styrene butadiene rubber reclaimed rubber blends were studied. The blends showed improved processability, as indicated by the minimum torque values. Cure characteristics like minimum torque, (maximum-minimum) torque, cure time and cure rate decreased in the presence of…
The hydrothermal and ceramic syntheses, single crystal structures and some properties of MnTe6O13, NiTe6O13 and CoTe6O13 are described. These isostructural phases [space group R (No. 148) with a ≈ 10.2 Å and c ≈ 19 Å] contain a dense network of isolated MO6 (M = Mn, Ni, Co) octahedra, TeO4 folded squares and distorted…
Kozoite-(La), (La, Nd, Ca)(CO3)[(OH), (H2O)], occurs in cavities of alkali olivine basalt at Mitsukoshi, Hizen-cho, Higashi Matsuura-gun, Saga Prefecture, Japan. Minute crystals of kozoite-(La) form a spherical aggregate with kozoite-(Nd). Concentric zoning textures of kozoite-(La) and kozoite-(Nd) can be observed on…
The phase diagram of the Mo–H system was determined by in situ X-ray diffraction using synchrotron radiation up to 1200°C and the hydrogen pressure to p(H2) = 5.3 GPa. Three phases were found to exist; a bcc phase (α) of low hydrogen concentrations at low hydrogen pressures, and two high-pressure phases, an hcp (ε) ph…
A new functional material with nonzero microwave absorption ability at zero applied magnetic field results from loading MCM-41 to a high percentage by weight with ferric oxide.
Raman spectroscopic investigations of the major lateral teeth of the chitons Acanthopleura rehderi and Acanthopleura curtisiana indicate that, in addition to the magnetite of the cutting surface and a carbonated hydroxyapatite in the central tooth core, these species deposit limonite in place of the lepidocrocite repo…
Part I of this two part series of papers has shown that existing pattern drafting methods are much less than adequate for drafting patterns to fit a wide range of body morphology. To solve this problem, this paper considers predicting shirt pattern parameters from 3D body measurements. Two prediction models are report…
