A Meaning-Based Approach to the Language of the TOEFL test and Japanese EFL Textbooks: A Functional Analysis of Patterns of Lexico-Grammatical Meanings and Structures
The primary objective of this research project is to show varying degrees of textual and semantic contributions that semantic density and grammatical metaphors make in the way that TOEFL iBT reading sections and Japanese EFL textbooks are used. This research is conducted from two theoretical perspectives within the theory of Systemic Functional Linguistics. The first analysis is to investigate logical and semantic relationships within clause complexes in order to identify structural variations and their textual distributions. The second analysis focuses on the use of ideational and interpersonal grammatical metaphors and on the way that they further compact or untangle textual meanings. This second analysis allows the researcher to unpack the semantic features and their density of lexico-grammatical meanings within each lexical item. The results from these analyses show a lexico-grammatical gap between the two language materials in terms of the density of grammatical metaphors distributed in the data sets. The findings may have the potential to be applied to Japanese EFL educational settings as one meaning-based perspective distinct from the current form-based EFL pedagogical practice

High-entropy effect at rare-earth site in DyNi
We report the structural and magnetic properties of RNi (R=Dy,
TbDyHo, and
GdTbDyHoEr) to investigate the
high-entropy effect at the rare-earth site. The lattice parameters are almost
unchanged by the increase of configurational entropy, which is due to the
successive partial substitution of Dy by pair of rare earth elements located on
both sides of Dy in the periodic table. All compounds exhibit ferromagnetic
ground states. The replacement of Dy with Tb+Ho, which does not have magnetic
interactions in competition with Dy, does not affect the magnetic ordering
temperature. Although (GdTbDyHoEr)Ni
shows the Curie temperature close to that of DyNi, an additional magnetic
anomaly, which would be a spin reorientation, is observed probably due to the
introduction of competing magnetic interactions between R=Gd and Er compounds
and R=Tb, Dy, and Ho ones. We have also assessed the magnetocaloric effect, and
the configurational entropy dependence of the magnetic entropy change reflects
that of the temperature derivative of the magnetic susceptibility. Our analysis
suggests the possibility of enhancing magnetocaloric properties by designing
the anisotropy of rare-earth magnetic moments in the high-entropy state.Comment: to be published in AIP Advance
Inverted type bulk-heterojunction organic solar cell using electrodeposited titanium oxide thin films as electron collector electrode
金沢大学理工研究域物質化学系We developed an inverted type bulk-heterojunction organic solar cell with 1 cm2 active area using a fluorine-doped tin oxide/electrodeposited amorphous (TiOx) or anatase (TiO2) titanium oxide electrode instead of the low work-functional electrode such as Al. The cell with TiO2 showed the power conversion efficiency (η) of 2.5% by irradiating AM 1.5-100 mW cm- 2 simulated sunlight. While, the performance of the cell with TiOx was almost maintained in an ambient atmosphere under continuous light irradiation of 10 h, although slightly small initial η value of 2.1% was observed.
