The magnetic properties of the films were measured, and the sample synthesized at 180C was found to exhibit the highest residual magnetization and coercivity of 1.5 emu/g and 134 Oe, respectively. The ferroelectric properties of all samples were similar, with a large remanent polarization of 5867 C/cm and a coercive field of 421462 kV/cm, regardless of the reaction temperature. Based on its magnetic and ferroelectric properties, the sample synthesized at 180C has potential as a practical multiferroic material.","PeriodicalId":23220,"journal":{"name":"Transactions-Materials Research Society of Japan","volume":"49 1","pages":"105-108"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75279397","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}

The influence of calcium ions present in the aqueous solution and pH on the phosphorus adsorption capacity of diopside was investigated. Diopside was found to adsorb a significant amount of phosphorus in the calcium-rich solution. In addition, its phosphorus adsorption ability tended to improve in aqueous solution s with lower pHs. In such solutions, calcium was eluted to a large extent from diopside. The adsorption rate of phosphorus in an aqueous solution of diopside was highly correlated to calcium elution. For solutions with low pH, the calcium bound to the OH group interacts with H+ and the charge on diopside becomes more positive. With this increasing positive charge, it can more effectively adsorb the negatively charged phosphate ions. It was assumed that calcium reacts with the phosphate ions and forms calcium phosphate on the diopside surface. The amount of phosphorus adsorption is related to the elution of calcium from diopside. We also found that natural diopside could be used as a phosphorus adsorbent in aqueous solutions without the need for adding calcium or adjusting pH.","PeriodicalId":23220,"journal":{"name":"Transactions-Materials Research Society of Japan","volume":"32 1","pages":"97-100"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73037513","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}

Based on X-ray diffraction (XRD) and Auger electron spectrometry analyses, the formation of approximately 2800-nm-thick surface oxide film on titanium consisting of rutile and anatase phases was confirmed. This oxide film on titanium contained many submicron-size pores. The anodized titanium plate was immersed in simulated body fluid, and evaluated using scanning electron microscopy and XRD. Low-crystalline hydroxyapatite formed on the surface after seven days of immersion. In contrast, a 270-nm-thick oxide film was produced on titanium plate anodized in phosphoric acid aqueous solution. In this instance, no additional layer was observed on the surface even after seven days of immersion in simulated body fluid. The biocompatibility was presumed to have improved in the titanium plate anodized using titanium oxide suspended in sulfuric acid aqueous solution electrolyte, because of the formation of a thick oxide film that contained a large number of pores. This material was thus found to be promising for use in implants.","PeriodicalId":23220,"journal":{"name":"Transactions-Materials Research Society of Japan","volume":"6 1","pages":"65-70"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86516515","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}

The electrical conductivities exhibit the thermal activation-type behaviors in the temperature region of 100~200°C. The activation energies of 200 and 600 nm films are 0.1 and 0.6 eV, respectively. The band gaps (Eg) of 200 and 600 nm films are ~2.6 and ~2.0 eV, respectively. The expanded PES in the Eg region and X-ray absorption spectra exhibit the W 5d-DOS at the Fermi level and defect-induced state at the bottom of conduction band, respectively.

However, the production of 99 m Tc solutions with heavy levels of radioactivity is difficult because the specific radioactivity of 99 Mo produced via this method is extremely low. Thus, it is necessary to develop a novel adsorbent with high Mo-adsorption efficiency. In this study, alumina (Al 2 O 3 ), which is often used in medical 99 Mo/ 99 m Tc generators, was used as the Mo adsorbent. Al 2 O 3 specimens were prepared with three types of starting powders and sintered at different temperatures; in addition, their Mo adsorption and desorption properties were evaluated. The results indicated that the Mo-adsorption properties are influenced by the crystal structure and the specific surface of the Al 2 O 3 . In addition, the basic chemical properties of the solution eluted from each developed Al 2 O 3 specimen were within the limits given by the guidelines.","PeriodicalId":23220,"journal":{"name":"Transactions-Materials Research Society of Japan","volume":"44 1","pages":"75-80"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76930489","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}
