概要:
In a permeable MgO ceramic containing TiO_2 and Al_2O_3 as matrix MgO ・ Al_2O_3-2MgO・TiO_2 solid solutions were detected
…
and no Al_2O_3・TiO_2 was observed. Therefore, the solid state reaction among MgO, TiO_2 and Al_2O_3 with excess MgO was studied at various firing temperatures. The formation mechanism of MgO・Al_2O_3-2MgO・TiO_2 solid solutions was studied from the results of interface reactions between MgO-TiO_2 and MgO-Al_2O_3. MgO・Al_2O_3-2MgO・TiO_2 solid solutions were detected at 1573-1673 K and increased with the firing temperature. 2MgO・TiO_2 was formed in the system MgO-TiO_2, but was not produced in the system MgO-TiO_2-Al_2O_3, because the amount of Mg diffusion at the interface of aggregate and matrix additives was not enough due to the large aggregate size of MgO. MgO・Al_2O_3 and 2MgO・TiO_2 formed at the interface between MgO-TiO_2 and MgO-Al_2O_3 decreased with the firing time at 1873 K. On the other hand, MgO・Al_2O_3-2MgO・TiO_2 solid solutions increased. Mg was recognized in the matrix without addition of MgO as a matrix. Al diffused in the layer of MgO-TiO_2, in opposition Ti diffused in the layer of MgO-Al_2O_3 by EPMA analysis. From the above results, the formation mechanism of a MgO・Al_2O_3-2MgO・TiO_2 solid solution was proposed; (1) Mg diffusion at the interface of MgO aggregate and matrix additives, (2) formation of MgO・TiO_2 and MgO・Al_2O_3, (3) formation of 2MgO・TiO_2 due to the reaction with MgO・TiO_2 and MgO, (4) reaction of the solid solution with MgO・Al_2O_3 and 2MgO・TiO_2. In the reactions between MgO・TiO2 and MgO-Al_2O_3 the product layer of MgO・Al_2O_3-2MgO・TiO_2 solid solution increased as the firing time increased. The diffusion coefficient of Mg was about 4.8×10^<-7>(cm^2/s), in a good agreement with that of Mg which was reported.

…
iamagnetic and paramagnetic compounds and in crystals having a modulated structure. The spectra and T1 of NMR in solids were measured for [M(H2O)6][AB6] crystals to investigate the static and dynamic structure of H2O and [M(H2O)6]2+ as well as the dynamics of the electron spin in the paramagnetic M2+ ion. The physical properties of [M(H2O)6] [AB6] were found to be as follows: (1) The spin-lattice relaxations of the electron spin of M2+ in [M(H2O)6] [SiF6] (M2+ = Fe 2+ , Co2+ , Ni2+) are dominated by the Orbach process, the Orbach process, and the Raman process, respectively. The spin-lattice relaxation of the electron spin of Cu2+ in [Cu(H 2O)6][PtCl6] is caused by jumping between the Jahn-Teller configurations. (2) In [Cu(H2O)6] [PtCl 6], H2O and [Cu(H2O)6]2+ undergo 180° flips and jumping between the different Jahn-Teller configurations, respectively. A weakening of the hydrogen bond O-H⋯Cl upon deuteration results in a lowering of the transition temperature. (3) In [M(H2O)6][SiF6], H2O and [M(H 2O)6]2+ undergo 180° flips and reorientation about the C3, axis, respectively. The order-disorder transition is closely related to a freezing of this reorientation. (4) By elongation of [M(H2O)6]2+ along the C 3 axis, the mobility becomes higher. (5) The disorder of [Fe(H 2O)6]2+ in the high-temperature phase of [Fe(H2O)6][SiF6] is dynamic. Rotational modulation of [Mg(H2O)6]2+ along the C 3 axis exists in the incommensurate phase of [Mg(H2O) 6] [SiF6].

概要:
Metabolism of 6-methyl-2-thiouracil was studied in rats by using ^<14>C-labeled compound. Following the oral administration of 6-methyl-2-thiouracil [2-^<14>C] (490 mg/kg), the about 68% of the administered radioactivity was excreted in
…
urine, 27% in feces, and 1.2% in respiratory CO_2 within 72 hr. After oral ingestion of the radioactive compound, radioactive substances excreted in urine after 48 hr were 6-methyl-2-thiouracil, 6-methyl-uracil, 6-methyl-2-methylthiouracil, 6-methyl-4-oxo-pyrimidine, 2-amino-6-methyl-4-oxopyrimidine, and urea which were present in about 46.2,9.1,1.6,1.8,0.2,and 0.8% of total radioactivity in the urine, respectively. In in vitro tests using rat liver slices, radioactivity was also detected in 5,6-dihydro-6-methyluracil along with the above metabolites.

概要:
The purpose of our study is to develop and to assess a method to calculate T1 and T2 relaxation times using fast spin-echo (FSE) sequences with two echoes per excitation. On a 1.5-T MRI, dual-echo FSE sequences with different repetition
…
times (TR:TR2=2TR1, i.e., TR1=400ms and TR2=800ms) were performed in MnCl2 phantom. Then, we assessed effects of the echo train length (ETL) , effective echo time (TE) , and T2 correction for T1 measurement, when changed each imaging parameter. Besides, we evaluated with comparison between the dual-echo FSE method and mixed sequence. With optimizing FSE imaging parameters, i.e., effective TE, TR, and low ETL, the measurement values of T1 and T2 revealed significantly higher correlation between the dual FSE method and mixed sequence. Moreover, the T2 correction to calculate T1 value could be omitted by shortening first effective TE. The dual-echo FSE method makes it possible to measure T1 and T2 fast and easily and to obtain more detailed information of organizations in human.

A method using the ^2H-NMR spectra was shown to be useful to study the solid state physics in diamagnetic and paramagnetic compounds and in crystals having a modulated structure.

The spin-lattice relaxation of the electron spin of Cu^<2+> in [Cu(H_2O)_6][PtCl_6] is caused by jumping between the Jahn-Teller configurations. (2) In [Cu(H_2O)_6][PtCl_6], H_2O and [Cu(H_2O)_6]^<2+> undergo 180° flips and jumping between the different Jahn-Teller configurations, respectively. A weakening of the hydrogen bond O-H…Cl upon deuteration results in a lowering of the transition temperature. (3) In [M(H_2O)_6][SiF_6], H_2O and [M(H_2O)_6]^<2+> undergo 180°flips and reorientation about the C_3 axis, respectively. The order-disorder transition is closely related to a freezing of this reorientation. (4) By elongation of [M(H_2O)_6]^<2+> along the C_3 axis, the mobility becomes higher.
