The Cu2ZnSnS4 (CZTS) semiconductor is a potential photovoltaic material due to its optoelectronic properties. These optoelectronic properties can be potentially improved by the insertion of intermediate states into the energy bandgap. We explore this possibility using Cr as an impurity. We carried out first-principles…

The properties of refraction of extraordinary rays at principal surfaces of a uniaxial crystal having a strongly anisotropic dielectric dispersion are studied. Subject to optical nonabsorptivity of the crystal, the criteria for characterizing the refraction behavior are derived from Maxwell's equations. The criteria r…

ITQ-21およびUSYゼオライトを用いてn-ヘプタンの異性化反応を200℃で行なった。異性化活性はUSYと大きな違いは観測されなかった。しかし、ITQ-21はUSYゼオライトに比べ炭素析出量が少なく、活性低下が少ないことが特徴である。ITQ-21骨格中のAl量が触媒特性に及ぼす影響を調べた。その結果、Alの量が増えるほど、骨格異性化の選択性が高くなった。

Introduction: As the use of metallic radionuclides increases, so does the demand for a simple production method. In this study, we demonstrated an in situ target processing concept for automated metallic radionuclide production without the use of any robotic device. Methods: An alumina ceramic vessel for a vertical ir…
【はじめに】近年、高精度な照射法が確立し複数回の放射線治療をうける患者も増加している。がんの局所再発のため近接部位に複数回放射線治療を行う場合、放射線障害のリスク低減のため、過去に計画した線量分布となるべく重複しない治療計画を行う必要がある。本研究では、複数回放射線治療を行う患者の過去の線量分布を、現在の治療計画CT画像と3次元的に非線形位置合せし融合表示することで、新たな治療計画を行う際に、過去の線量分布の正確な位置を把握できる方法を開発することを目的とする。従来検討した手法では、演算時間に数十時間程度を必要とし改善を要した。【方法】非線形位置合せにはオープンソースの医用画像処理ソフトウェアシステムThe Insight Too…
Effect of lamellar orientation on cracking behavior of the α2/γ lamellar single crystals made by directionally solidified has been examined, by means of in-situ three-point bend test in SEM. The single crystals were grown by optical floating zone furnace. As-grown crystal exhibits fully lamellar microstructure, with 2…
Morphological and cytochemical characteristics of neutrophil from flatfishes（marbled sole Pleuronectes yokohamae, barfin flounder Verasper moseri）were examined by light microscopy. The shape of neutrophils in both fish was round to oval（8.0-11.0 μm in diameter）and the nucleus round to lobule-shaped. Only one type of g…
In the methylene blue (MB)/phenylalanine (Phe)/tungsten(VI) oxide (WO 3 ) colloid ternary aqueous solution, the MB Haggregates, which could recognize the chirality of D-and L-10 Phe, were formed and investigated by means of UV-Vis absorption and CD spectroscopy.These results demonstrate a chirality transfer and amplif…

Possibility of criticality of fuel debris in a form of UO$_2$-concrete mixture is evaluated by calculating infinite multiplication factor ($k_\infty$) for a study of criticality control on the fuel debris generated through the molten core concrete interaction (MCCI) in a severe accident of a light water reactor (LWR).…
Creep behavior of carbon free Fe-20Cr-30Ni-2Nb (at.%) steels strengthened by Fe2Nb Laves phase at 1073 K has been examined in air and water vapor atmosphere, in order to identify the effect of water vapor on creep properties. The steel studied has the compsition with 0.03 at.% B. Solution treated (1473 K/2 h) specimen…
