Carbon nanofiber (CNF)/unsaturated polyester resin (UPR) was prepared by a solvent evaporation method, and the temperature dependency of electrical conductivity was investigated. The CNF/UPR composites had quite a low percolation threshold due to CNF having a larger aspect ratio and being well dispersed in the UPR mat…
A novel emi-flective display which integrates a reflective liquid crystal display (R-LCD) and an organic light emitting diode (OLED) was demonstrated, whose OLED achieved a gain factor of 8 in contrast ratio (CR) compared with the conventional OLED. Under the high light ambience, the R-LCD is sustained with the CR of…
In this paper, we investigate the contribution of deep and shallow trapped ions on the second-order nonlinearity during typical poling procedures in soda-lime glass. The zero-electric field potential barriers of each contribution were estimated. The shallow traps, measured through the electrical ionic current, was det…
A series of new pyridine-containing diisocyanates bearing bulky aryl groups, 4-aryl-2,6-bis(4-isocyanatophenyl)pyridines (DIC1−3), was successfully synthesized by Weinstock modification of the Curtius rearrangement of the corresponding diacids, 4-aryl-2,6-bis(4-carboxyphenyl)pyridines (DA1−3). These diisocyanates were…
Photochemical and enzymatic synthesis of malic acid from pyruvic acid and HCO3- was studied with malic enzyme (ME) and NADP+ photoreduction with ferredoxin-NADP+-reductase (FNR) by visible light photo-sensitization of the chlorophyll derivative, zinc chlorin-e6 (ZnChl-e6), in the presence of NADH as an electron-donati…
A simple, low coherence, vibration insensitive, polarization Fizeau interferometer is employed in this novel optical monitoring system proposed to extract the temporal phase change of the reflection coefficient of the growing film stacks. This system can directly detect fluctuating reflection coefficient and obtain th…
The influence of frequency on fatigue crack growth (FCG) behavior was investigated for three differently heat-treated 17-4 PH stainless steels, namely unaged “Condition A,” peak-aged “Condition H900,” and overaged “Condition H1150,” at 673 and 773 K, and at frequencies ranging from 0.002 to 20 Hz. At 773 K, all heat-t…
A mixture of low-molecular-weight poly(L-lactide-co-glycolide ethylene oxide fumarate) (PLGEOF) macromer and high-molecular-weight poly(lactide-co-glycolide) (PLGA) was used to produce fibers by electrospinning. PLGEOF is a biodegradable and in situ cross-linkable terpolymer made from building blocks with excellent bi…
CBB 試験及び隙間付き UCL 試験により各種溶体化オーステナイトステンレス鋼の高温水中 SCC 感受性について検討した結果，以下の点が明らかになった．(1) 隙間環境及び高負荷応力下において，304，304L，316L，316NG 及び 347NG はいずれも高温水中 SCC 感受性を発現する．(2) 加工誘起マルテンサイトは溶体化オーステナイトステンレス鋼の高温水中 SCC に対する促進要因であるが必要要因でない．(3) 高温水中 SCC 感受性の材料序列及び冷間加工の影響は CBB 試験と隙間付き UCL 試験において異なる．これは，両試験法における応力負荷時のひずみ量の相違に起因する．
One way for the reuse of reverse osmosis (RO) concentrates and thus increasing the water recovery is to recycle part of the brine concentrate to the feed, after precipitating the scaling salts such as CaSO4/CaCO3 held in solution by antiscalants. However, antiscalants impart considerable stability to the supersaturate…
The linear, second-order, and third-order, dielectric susceptibilities χ1, χ2, χ3, of triglycine sulphate (TGS) single crystal have been measured using dynamic method. The second-order dielectric susceptibility has non-zero value in ferroelectric phase and vanishes near the temperature of ferroelectric phase transitio…
Measurements of crystalline lattice strain development during deformation of polytetrafluoroethylene (PTFE) have been performed utilizing neutron diffraction measurements at the SMARTS diffractometer at Los Alamos National Laboratory. The chemical structure of PTFE, (C 2 F 4 ) n , makes it ideally suited for investiga…
The mass attenuation and energy-absorption coefficients (radiation interaction data), which are widely used in the shielding and dosimetry of X-rays used for medical diagnostic and orthovoltage therapeutic procedures, are strongly dependent on the energy of photons, elements and percentage by weight of elements in bod…
Scale deposition is one of the most important and serious problems which water injection systems are generally engaged in. Scale sometimes limits or blocks oil and gas production by plugging the oil-producing formation matrix or fractures and perforated intervals. Scale also deposited in down-hole pumps, tubing, casin…
生物医学的材料的表面上的蛋白质吸附行为是高度与材料的 biocom-patibility 有关。在过去，众多的研究报告主要集中于材料的化学部件的效果“蛋白质吸附上的 s 表面。蛋白质吸附上的表面地形学的效果，这评论的话题，最近收到了热切的兴趣。表面的影响 nano 地志的因素，包括的粗糙，弯曲和几何学在蛋白质吸附以及蛋白质上，吸附行为例如吸附的蛋白质的数量，吸附的蛋白质的活动和形态学，被介绍。
We study the Euclidean effective action per unit area and the charge density for a Dirac field in a two--dimensional spatial region, in the presence of a uniform magnetic field perpendicular to the 2D--plane, at finite temperature and density. In the limit of zero temperature we reproduce, after performing an adequate…
Atomic- and void-species nanostructures are studied in As 2 S 3 glass in unmodified and γ-modified states using a combination of conventional X-ray diffraction in respect to the first sharp diffraction peak, synchrotron-based high-energy X-ray diffraction and extended X-ray absorption fine structure spectroscopy. The…
Polypyrrole film was photoelectrochemically grown on insulating Ta 2 O 5 anodic film in acetonitrile solution. A characterization by photocurrent spectroscopy (PCS) of metal/oxide/polypyrrole interface was carried out. The PCS results suggest that a metallic-like PPy is formed under illumination at constant anodic pot…
Dynamic water absorption properties of terry fabrics were investigated experimentally using 216 various terry fabric samples of different construction. It is shown that around 26% to 40% of water is absorbed during the first 10 seconds, depending on the fabric construction; the percentage of water absorption exceeds 5…
Phenylphosphonic acid ( H 2 PP ) dissolved in a polyvinylbutyral coating is shown to profoundly inhibit filiform corrosion (FFC) on coated AA6111-T4. Following FFC initiation by application of aqueous HCl to a penetrative coating defect, the time-dependent extent of coating delamination was determined both optically a…
