Fuel Cell Using Squid Axon Electrolyte and Its Proton Conductivity
No full textFuel cells using biomaterials have the potential for environmentally friendly clean energy and have attracted a lot of interest. Moreover, biomaterials are expected to develop into in vivo electrical devices such as pacemakers with no side effects. Ion channels, which are membrane proteins, are known to have a fast ion transport capacity. Therefore, by using ion channels, the realization of fuel cell electrolytes with high-proton conductivity can be expected. In this study, we have fabricated a fuel cell using an ion channel electrolyte for the first time and investigated the electrical properties of the ion channel electrolyte. It was found that the fuel cell using the ion channel membrane shows a power density of 0.78 W/cm2 in the humidified condition. On the other hand, the power density of the fuel cell blocking the ion channel with the channel blocker drastically decreased. These results indicate that the fuel cell using the ion channel electrolyte operates through the existence of the ion channel and that the ion channel membrane can be used as the electrolyte of the fuel cell in humidified conditions. Furthermore, the proton conductivity of the ion channel electrolyte drastically increases above 85% relative humidity (RH) and becomes 2 × 10−2 S/m at 96% RH. This result indicates that the ion channel becomes active above 96%RH. In addition, it was deduced from the impedance analysis that the high proton conductivity of the ion channel electrolyte above 96% RH is caused by the activation of ion channels, which are closely related to the fractionalization of water molecule clusters. From these results, it was found that a fuel cell using the squid axon becomes a new fuel cell using the function of the ion channel above 96% RH
Anhydrous Proton Conductivity in HAp-Collagen Composite
No full textIt is well known that a proton conductor is needed as an electrolyte of hydrogen fuel cells, which are attracting attention as an environmentally friendly next-generation device. In particular, anhydrous proton-conducting electrolytes are highly desired because of their advantages, such as high catalytic efficiency and the ability to operate at high temperatures, which will lead to the further development of fuel cells. In this study, we have investigated the proton-conducting properties of the hydroxyapatite (HAp)-collagen composite without external humidification conditions. It was found that, by injecting HAp into collagen, the electrical conductivity becomes higher than that of the HAp or the collagen. Moreover, the motional narrowing of the proton NMR line is observed above 130 °C. These results indicate that the electrical conductivity observed in the HAp-collagen composite is caused by mobile protons. Furthermore, we measured the proton conduction of HAp-collagen composite films with different HAp contents and investigated the necessity of the appearance of proton conductivity in HAp-collagen composites. HAp content (n = 0–0.38) is the number of HAp per collagen peptide representing Gly-Pro-Hyp. These results indicate that injection of HAp into collagen decreases the activation energy of proton conduction which becomes almost constant above a HAp content n of 0.3. It is deduced that the proton-conduction pathway in the HAp-collagen composite is fully formed above n = 0.3. Furthermore, these results indicate that the value of the activation energy of proton conductivity was lowered, accompanied by the formation of the HAp-collagen composite, and saturated at n > 0.3. From these results, the HAp-collagen composite forms the proton-conduction pathway n > 0.3 and becomes the proton conductor with no external humidification in the condition of n > 0.3 above 130 °C

This article appeared in Tokiyoshi Umeda, Yuuki Hashimoto, Hiroyoshi Mizukami, Tomoki Shirakawa, Akihiko Fujii, and Katsumi Yoshino, Appl. Phys. Lett. 85, 3139 (2004) and may be found at https://doi.org/10.1063/1.1804234.Photovoltaic properties of heterostructure devices of titanium oxide (TiO2) and conducting polymer thin films have been studied. Normal photovoltaic properties were stably observed upon the visible light irradiation of the wavelength range corresponding to the absorption of a conducting polymer, and unique photovoltaic properties were also observed upon the ultraviolet (UV) light irradiation of the wavelength range corresponding to the absorption of TiO2. UV light irradiation caused marked increases in the short-circuit current at the visible-wavelength range and in the open-circuit voltage. These properties have been discussed by considering the enhancement of the built-in field which originates from the hole accumulation caused by the trap levels in the TiO2 layer or TiO2 ∕ conducting polymer interface.

<Review Articles>R.D .Hill. Rice in Malaya : A Study in Historical Geography. Oxford University Press. 1975

Rice in the prehistoric and early historic cultures of Southeast Asia is described in the first two chapters, which cite archaeological and historical evidence for the age and area of origination of rice cultivation and its spread to the Malay Peninsula. Rice cultivation had become widespread throughout the peninsula by the beginning of the nineteenth century, and chapter 3 illustrates the cycle of operations involved in shifting, semipermanent and permanent cultivation at that time. It also describes land tenure and the gradual changes in the concept of land as real property in Malayan society. As a means to understand the diversity of development of rice cultivation, the author proposes that four major regions of rice cultivation emerged between the nineteenth and the early twentieth century. The first is the northern region centered upon Kedah, the colonized lands of Penang and Province Wellesley, and Kelantan, Trengganu. Perak, apart from the tin-mining areas in the south, is also included and offers a fine example of development under British rule. Second, the southern region includes the plain of Malacca, which is largely non-Minangkabau in its techniques, tradition and law, together with the contrasting Minangkabau lands of Negri Sembilan. The third region, which includes southern Perak, the whole of Selangor and Pahang, comprised the 'marches' areas, where rice-growing was of little importance. The fourth region, that of the hill peoples, was only partly known during the nineteenth century. The remaining chapters focus mainly on the northern and southern centers of rice cultivation, dealing with the traditional or common cultivation methods and their distribution; acreages of paddy fields, with many statistical data on land-ownership and the races engaged in rice-growing; the socioeconomic background; and schemes for expansion of rice cultivation, the motives behind them and the fates they met. The discussion on the expansion of cultivated area in relation to the regional pattern of economic development in a colonized area indicates that large-scale development succeeded more often under Malay initiative than British. Finally, the author proposes a typological scheme which comprehends all the spatial patterns of rice-growing in the Malay Peninsula. The scheme could be used to classify the ecotypically varied pattern of rice-growing, but difficulty remains in its application to evolutional development, because multi-ancestral and different types of rice-growing were introduced into the peninsula in different ages and in different areas. On the origin and dispersion of cultivated rice in the Malay Peninsula and adjacent areas, a more detailed and precise theory should be provided by recent studies in this field. Throughout this volume, the author has successfully combined geographical and historical approaches in depicting rice in Malaya
