Nanometer thin films of Nafion ionomer interfacing with platinum form the functional electrode in many electrochemical devices including fuel cells and electrolyzers. To impart facile proton conduction in Nafion ionomer, sufficient hydration of Nafion ionomer is necessary to create a percolating network of water-filled nanometer sized hydrophilic domains that manifests as macroscopic swelling. This hydration behavior of ionomer thin films is poorly understood especially for films confined on electrochemically relevant Pt substrates. In this work, we present the evolution of hydration-dependent microscopic hydrophilic domains and macroscopic expansion of 55 nm thin Nafion film on a Pt substrate. The cross-correlation among the film macro-expansion from ellipsometry, the micro-expansion from GISAXS, and the water distribution from neutron reflectometry (NR), explains the observed non-affine behavior of the film which can be attributed to the randomly and spatially non-uniform distribution of water domains. A correlation between macroscopic factor (ε/τ) for protonic conductivity, and the domain size and swelling is presented for the first time. In addition, interfacial water between Pt and the ionomer interface estimated at 75% and 84% RH, and increase in domain size with RH, are discussed to explain increased activity and oxygen diffusivity with RH.

三島由紀夫は「海と夕焼」 (昭和三〇年) の主題を「奇蹟自体よりもさらにふしぎな不思議」であると述べた。本論文では<子供十字軍>の史実から本作の虚構性の特質を捉えたうえで、現在の安里が過去に体験した「不思議」をどのように受け止めているのかについて考察した。<海> の象徴性、<夕焼> の終わりとともに「梵鐘の音」が響く結末、<眠る少年> の意味等から、仏教的(禅的)世界の枠組みが「不思議」へのこだわりを消し去るものとして機能していたことを明らかにし、「不思議」の再来を願わないと言いうる境地にいたった三島文学の様相をもとに『金閣寺』 の新たな読解可能性を提示した。

Well-defined silver dendrite nanostructures with primary and secondary branches on a glassy carbon electrode (GCE) surface are first demonstrated using a simple wet chemical electroless deposition method without any aid of a surfactant. The properties of dendrite structures were characterized using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS). Results of XPS and XRD indicated that most of the silver particles were not oxidized. The obtained silver dendrite GCE (Ag/GCE) showed high electrochemical activity towards catalytic oxidation for ascorbic acid (AA). The oxidation process followed a stepwise mechanism at slower scan rates (υ < 0.15 V s^<-1>) and a concerted mechanism at faster scan rates (υ > 0.15 V s^<-1>). The silver nanostructures are highly stable on the GCE surface and could be employed as an anode for an AA fuel cell.

Lists of meteorites in Japan, Korea and China have been compiled. A summary of the results reveals that the meteorites which have been studied so far are 30 in Japan, 3 in Korea, and 6 in China. Of the 29 witnessed to fall, 25 are aerolites, 1 is a siderolite, and 3 are siderites. Of those found whose fall was not witnessed, 2 are aerolites, and 8 are siderites.

著者らが開発したガスクロマトグラフ法を用いて、昭和57(1982)年から平成9(1997)年の16年間に、95種類(104試料)の野菜中の水溶性シュウ酸及び総シュウ酸の定量を行った。「ふだんそう」及び「つるな」には水溶性シュウ酸が、「おかひじき」及び「ふだんそう」には総シュウ酸が極めて高濃度に含まれていた。総シュウ酸に占める水溶性シュウ酸の割合の高い野菜は「生たけのこ」、「しょうが」、「ゆでたけのこ」及び「ルバーブ」であり、逆に低い野菜は「モロヘイヤ」であった。「生たけのこ」中の水溶性シュウ酸は、米糠を加えてゆでることにより半量近くに減少した。「ほうれんそう」もまた、ゆでることにより、その水溶性シュウ酸は半量以下にまで減少した。いわゆる「あく」のある山菜として知られる、「ぜんまい」、「ふきのとう」、「やまごぼう」及び「わらび」の両シュウ酸は何れも十数mg%と少なかった。「キャベツ」など9種類の野菜は水溶性シュウ酸及び不溶性シュウ酸共にゼロであった。@@@Determinations of soluble and total oxalic acids in 95 vegetables (104 samples) have been made over 16 years from 1982 to 1997 by the gas chromatographic method which had been established by the author and his colleagues. 'Chard' and 'New Zealand spinach' contained a very high quantity of soluble oxalic acid and 'Saltwort' and 'Chard' total oxalic acid, respectively. Vegetables with an extraordinarily high ratio of soluble to total oxalic acid included 'Raw and boiled bamboo shoots', 'Ginger' and 'Rhubarb', whereas the vegetable with the lowest ratio 'Jew's marrow'. As for 'Raw bamboo shoots', soluble oxalic acid content diminished almost by half when they were cooked in boiling water with rice bran added. Soluble oxalic acid in 'Raw spinach' also diminished to below half when cooked in boiling water. Oxalic acid contents were unexpectedly low in vegetables with lye, namely 'Royal fern', 'Flower-cruster', 'Yamagobō' and 'Bracken'. Nine vegetables including 'Cabbage' contained neither soluble nor insoluble oxalic acid.

There are four major nominal classes in the Burushaski language andall nouns are classified into the following groups according to their referents:human males, human females, concrete entities, and abstract entities.This paper demonstrates that the inherent noun classification system of theBurushaski variety spoken by the younger generation of immigrants in theBota Raj colony in Srinagar is decaying and being reconstructed in analtered form.Noun classification systems are generally dynamic and may decline innumber or even become lost altogether. Some languages have (partially)lost their classification systems through contact with other languages thathave simpler noun classification systems or no classification systems at all.Some languages have neutralised previously distinct classes into a newclass, decreasing the overall number of classes as a result.However, the Srinagar Burushaski of young people does not merelydemonstrate the decay of nominal classes. Having initially lost the basis ofcategorisation for noun classification, they have since re-categorised allnouns, thereby avoiding incoherency in the nominal class system. As aresult, the number of reconstructed nominal classes has increased to five:human males, human females, animals, concrete entities, and abstract entities.It is worth noting that no adjacent languages have a noun classificationsystem that specifically distinguishes animals from others.
