The CFRTP/NiCF/Al joint part was strengthened by impregnated nickel-coated carbon fibers (NiCF) to prevent aluminum carbide formation, as well as to enhance the ability of fiber rapping by molten aluminum. The universal joint exhibited the extremely higher safety level of resistance to tensile stress and apparent hardening modulus at each strain than that of the joint without carbon fiber.","PeriodicalId":14991,"journal":{"name":"Journal of Advanced Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73670343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, efficiency of DSC is low. Many researches on chemical characteristics and shape of titania and dye to improve efficiency are carried out. We applied electrostatic inkjet technology for patterning titania layer of DSC because fabrication process should be developed to contribute to high efficiency. New machine that can print titania is essential to fabricate DSC on various surface of flexible electronics. The optimized thickness of titania layer is changed when the titania and dye are changed of type. Traditionally, doctor blade method and screen print method has been used to fabricate titania layer. However, these methods are not suitable to optimize thickness of titania layer. In this paper, we developed the machine to print titania layer. We demonstrated that thickness of titania layer depends on printing time and efficiency is changed when thickness of titania layer is changed.","PeriodicalId":14991,"journal":{"name":"Journal of Advanced Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72877940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At Tm, the relaxation strength, relaxation time, and relaxation time distribution change adruptly, and their subsequent changes with decreasing temperature are larger than those above Tm.

Obtained signal waveforms under two separate conditions were compared and analyzed. In both conditions, a descending transmitting signal was observed. However, remarkable readiness activity of the motor cortex was not seen in both cases with a 5 times averaging. Using our experimental model, neurophysiological characteristics of motor generation were revealed.

But most unreacted fuel is exhausted out of fusion reactor. Especially, Tritium is radioisotope and rarely exists in nature, so fuels recovery is necessary. Therefore, we propose a separation on divertor region by using hydrogen storage material. In this study, we have proposed fuel particles recovering on divertor with titanium in the type of a hydrogen storage material by using divertor simulator TPD-SheetIV via deuterium plasma. After deuterium plasma exposures, the samples were analyzed by thermal desorption spectroscopy (TDS). The temperatures of the samples were increased up to 1093K.
