Some comments on the practical science education

Wataru Ishizuka, Noriyoshi Kimura, Hideki Takasu, Kunihiko Hisatomi

Bulletin of the Faculty of Education, Wakayama University. Educational science ( Faculty of Education, Wakayama University )  58   75 - 78   2008.02

　View Summary

We report on our unique education program for science teacher that includes many familiar environments or simple experiments. It has been already proved that the practical science education is very effective to make students be interested in the class. In elementary schools and junior high schools, however, it has become difficult to perform practical observations or experiments in a science class. One of the reasons is the lack of teachers' skills. In addition, it must be stressed that scientific knowledge is crucially important for science teachers. It is desirable that students learn the teaching skills at schools, as well as study the science theories hidden behind the easily discernible phenomenon at the university. These two factors, theory and practice, must be balanced to train good science teachers.

Metal valence and spin structures in 1-D Ni-Pd mixed-metal complexes, [Ni1-xPdxBr(chxn)2](NO3)2 (0.00≤x≤1.00), studied by 13C NMR and ESR measurements

Aki Josako, Noriyoshi Kimura （Part： Last author,　Corresponding author )

Bulletin of the Faculty of Education, Wakayama University. Natural science ( Faculty of Education, Wakayama University )  58   31 - 34   2008.02

　View Summary

13C solid-state NMR and ESR spectra were observed in [Ni1-xPdxBr(chxn)2] (NO3)2 (0.00<x<1.00; chxn: 1R, 2R-diamonocyclohexane), where the antiferromagnetically coupled paramagnetic-Br-Ni3+-Br-Ni3+-Br- chains are formed at x= 0.00, while the mixed-valence-Br-Pd2+-Br-Pd4+-Br- state is formed at x= 1.00. The 13C NMR signals at Cα coordinating to Ni atoms in mixed-metal complexes afforded the marked decrease of intensity with increasing x from 0.00. This result seems to be attributed to the effect of the strong spin fluctuation on paramagnetic Ni3+ sites, and was supported by ESR spectrum measurement.

Bulletin of the Faculty of Education, Wakayama University. Natural science ( Faculty of Education, Wakayama University )  56   17 - 19   2006.02

　View Summary

The carbon-13 NMR chemical shifts for thirteen 2-substituted fluorenes have been measured in chloroform-d at 100MHz. The substituent induced chemical shifts (SCS) for C11, showed an inversed trend where as SCS for C7 exhibited normal trend in the sense of the substituent electronic effect. These phenomena are as good as those observed for the SCS of the corresponding carbons of the 4-substituted biphenyls. The π electrons of the remote benzene ring were polarized by the charge of the substituted phenyl moiety.

Bulletin of the Faculty of Education, Wakayama University. Natural science ( Faculty of Education, Wakayama University )  56   31 - 33   2006.02

　View Summary

We performed the DSC, X-ray and UV-Vis spectrum measurements on [Pt(en)2] [PtBr2(en)2] (ClO4)4 in which a modification was reported by crystallizing from aqueous solution below room temperature. A metastable phase crystallizing below room temperature showed a different phase transition with thermochromism at ca. 380K to the stable form. The obtained X-ray powder patterns confirmed that the phase transition at 380K was transformation into the stable form.

Dynamic behavior of H2O molecules in [Pt(en)2] [PtX2(en)2] (SO4)2・6H2O studied by 2H and 1H NMR

Mami Oe, Noriyoshi Kimura （Part： Last author,　Corresponding author )

Bulletin of the Faculty of Education, Wakayama University. Natural science ( Faculty of Education, Wakayama University )  56   27 - 29   2006.02

　View Summary

We measured the temperature dependences of 2H NMR spectra and 1H spin-lattice relaxation time (T1) in [Pt(en)2] [PtX2(en)2] (SO4)2・6H2O (X: Cl and I). The obtained 2H NMR spectra and 1H T1 at T>250K were attributable to the 180°flip motion of the water molecule. The activation energy and the correlation time at infinite temperature for the 180°flip of H2O were evaluated to be Ea= 27 kJ mol-1 and τ0=1.0×10-13 s, respectively. These results suggest that the network of the hydrogen bond through H2O molecules is strongly linked in the crystal.
