Most of the calculations of electronic properties of transition metal oxide have been based on the local density approximation (LDA) in the density-functional theory (DFT).However, because of the well-known deficiency of the LDA, there exists a serious discrepancy between the Kohn-Sham (KS) eigenvalues and the experim…

Co-60線質での電離箱線量計の水吸収線量による校正では，一次標準および二次標準の段階では厚さ1mmのアクリル製防浸鞘が用いられる。一方，防水タイプの電離箱を使用するユーザーの大半は防浸鞘を使わず，電離箱を直接水に入れて計測を行っている。本研究では，防浸鞘の有無が電離箱出力に及ぼす影響の評価を計測と計算の両面で進めているが，計算に用いるEGS5のプログラム中の光子の偏光の取り扱いに不具合のあることが判り，ここでは修正されたコードを用いて，防浸鞘の影響を再評価した。修正されたプログラム（EGS5, version1.05)を用いた結果では，ICRU37の阻止能を使うとCo-60線質でのアクリルの水透過性をよく再現しており，測定結果が…
The Soeda Granodiorite is distributed in eastern part of the Cretaceous granitic rocks in northern Kyushu.This granodiorite is mainly composed of medium-grained hornblende-biotite granodiorite to biotite granite, and divided into main and hornblende porphyritic facies.The hornblende porphyritic facies are distributed…
The reaction mechanism of all-solid-state lithium–sulfur batteries was studied by small- and wide-angle X-ray scattering. The results revealed that sulfur deposited in the electrode framework has a random distribution on the carbon wall of the highly ordered mesoporous carbon, CMK-3. Heat treatment complicated carbon…
Previously, 14.0% efficiency on pure-sulfide CuInGaS2 single cell was reported by Solar Frontier K.K.[1]. Regarding open circuit voltage, 960 mV was achieved. In this work, we tried the development of the puresulfide CuInGaS2 submodule via monolithic structure. For the fabrication, vacuum-based processes were used for…

Structures and ionic conductivities of the new perovskite oxides and pyrochlore oxyflurides were investigated. Solid solutions of the new perovskite oxides, (LixSr1-x-y)(Ga[(1-x)/2]-yTa[(1+x)/2]+y)O3, were synthesized using a ball-mill-assisted solid-state reaction with the composition range of 0 ≤ y ≤ 0.20. The highe…

La entrega de estos certificados de calidad surge como respuesta a una serie de informes por parte de l…
Minutes of the Membership committee lists the activities and accomplishments of the committee for the current year.
Effects of fabric constructional parameters on the prediction of percentage reflectance of woven polyester fabrics for different weft yarn densities have been investigated considering the same yarn count and weave pattern. Relationship among weft yarn density, fabric bulk density, fabric cover factor and percentage re…

Cancer is a highly complex disease and the most common treatments are limited to chemotherapy, radiation and surgery. However, the occurrence of side effects is frequent, especially due to limited drug capability to act specifically on cancer cells. The anthracycline antibiotic doxorubicin (DOX) is widely used in canc…
Há a necessidade de se compreender os processos de formação do solo em diferentes paisagens para prever como as propriedades do solo irão responder às mudanças no uso do solo. Neste estudo, objetivou-se caracterizar Cambissolos em uma região montanhosa sob clima subtropical de altitude no Sudeste do Brasil, por meio d…

[[abstract]]文章採用深冷處理也稱為超低溫處理對聚丙烯腈基碳纖維進行介面改性。將處理前和處理後碳纖維的介面性能進行對比研究。通過對碳纖維與環氧樹脂進行微滴實驗表明，深冷處理後碳纖維的介面剪切強度（IFSS）提高了29.5%。原子力顯微鏡（AFM）顯示處理後纖維表面變粗糙，這與IFSS的結果一致。採用和X射線衍射(XRD)對碳纖維的結構進行表徵，結果表明處理後纖維結構存在一些物理變化。 In this study, PAN-based carbon fiber was selected to undertaking bulk modification through ultralow temperature also ca…
[[abstract]]本研究是以聚酯紗為經緯紗，在梭織物打樣機製備出各種不同密度的聚酯織物，再以熱壓成型使聚酯織物與聚乳酸結合形成複合材料，並且比較各種不同比例補強的複合材料抗拉強度、硬度、衝擊強度、熱變形溫度等物性。經研究結果可知，在機械性質方面，會因為PLA中加入聚酯纖維的比例增加使得抗拉強度和衝擊強度有所增加，而硬度和熱變形溫度沒有明顯的改變。 The high performance fabrics textured by the various ratios of nylon/high strength PE yarn as the weft and the polyester yarn as the warp wit…

© 2015 Author(s). A hallmark in the cuprate family of high-temperature superconductors is the nodal-antinodal dichotomy. In this regard, angle-resolved photoemission spectroscopy (ARPES) has proven especially powerful, providing band structure information directly in energy-momentum space. Time-resolved ARPES (trARPES…
[[abstract]]本研究利用鎳線和鐵線的導磁特點，使用兩種纖維去製成平紋織物，以鎳線為經紗，鐵線為緯紗，再以增加電磁波多重反射空間的材料，去製成不同鎳線隔距的織物，與改變鐵線根數的方式以及比較有無PE管對電磁波吸收值的影響，由參考文獻中指出，在導電的線材中，吸收電磁波在中高頻的部分有良好的效果，但是在低頻的部分效果不佳由於從參考文獻中看到了導磁性線材對電磁波吸收值之頻率範圍在低頻有良好效果，所以為了提升低頻寬率與電磁波吸收效益故加入了鎳線與鐵線當作本實驗的導磁材料。而本實驗的結果鎳線隔距在1cm時達到了最好的吸收效果為18dB值，達到98.4%的電磁波吸收率與在鐵線根數為3的時候達到最好的吸收效果為24dB值，達到99.7%…
