A highly sensitive and selective analysis of alkali metal and ammonium ions was investigated on the basis of a Förster-type excitation energy transfer between two quantum dots (QDs) with different sizes. QDs are semiconductor nanoparticles and their emission wavelengths depend on their sizes. For the molecular recogni…
導電性バナジン酸塩ガラスの電気物性と局所構造の相関に関する最近の研究成果を紹介した。バナジン酸塩ガラスはVIV(あるいはVIII)―O―VV間の電子ホッピングにより10－7～10－5 S cm－1の導電率を有することで知られている。20BaO・70V2O5・10Fe2O3ガラスについて，DTA測定により判明した結晶化ピーク温度(Tc)近傍の500℃の熱処理で導電率が10－5から100 S cm－1へ上昇した。メスバウアースペクトルから，このときFeO4四面体の歪みを反映する四極分裂(Δ)の値は0.70から0.54mm s－1に減少することが判明した。バナジン酸塩ガラスは熱処理で構造緩和が起こり局所的な歪みが減少し，その結果電子ホッ…
大分工場は，1・3・5マシンの3台の抄紙機を有し，ライナー原紙を主に，石膏原紙・白板紙・色板紙・紙管原紙等の板紙を抄造している。段ボール古紙の使用割合は8割程度を占めており，段ボール古紙処理系列のリジェクトパルプ削減が大分工場の歩留まり改善に繋がると言っても過言ではない。本稿では段ボール古紙処理工程最終スクリーンに，株式会社IHIフォイトペーパーテクノロジー社製コンビソータを導入し歩留まり改善を図ることが出来た事例を紹介する。
Some investigations of ZnO-rGO nanocomposite thin films with various ratios of rGO and ZnO prepared by sol–gel method are done in this work. It is seen that the resistivity of samples decreas by increasing the rGO content in the composite films,. For photodetector application we have chosen a specific ratio of ZnO and…
Combining the Sachs deformation model with the dislocation theory, we can predict the stress-strain curve for both face centered cubic (FCC) and body centered cubic (BCC) single crystals generally. Residual dislocation densities are estimated from total amount of microscopic slip, considering cross-slipped dislocation…
The most efficient electric devices in nature will be the light harvesting system in biological membrane. Photosensitive proteins complex, such as photosystem I (PS I), photosystem II (PS II), and electron transport proteins complex such as cytochrome were hierarchically assembled in the bilayer membrane based on thei…
In this review, we report isolation of unstable tri-sulfur, S3, in a porous coordination network which is used as a crystalline molecular flask. The ozone-like structure of S3 in a pore was determined by ab initio X-ray powder diffraction analysis. The S3 in the pore was interacted with iodine which faces to the pore…
As the structure of biofilms plays a key role in their resistance and persistence, this work presents for the 11 first time the numerical characterization of the temporal evolution of biofilm structures formed by three 12 Listeria monocytogenes strains on two types of stainless-steel supports, AISI 304 SS No. 2B and A…
DNA sequencing currently lacks optical based techniques such as Raman spectroscopy. We have identified previous issues that prevented sequencing with Raman measurements and proposed a solution for base pair identification via surface enhanced Raman spectroscopy.
用水冷铜模吸铸法制备Ti86.5Nb7.5Mo4Sn2（at%,下同）合金,将合金在室温下进行了冷轧（变形量为80%）,然后在973 K,不同保温时间下对合金进行了退火。研究了退火时间对合金显微组织及其超弹性的影响。结果表明,冷轧后得到了晶粒细长的变形组织,该组织在973 K下固溶处理后发生了再结晶,形成了细小的等轴晶粒组织。冷轧后的合金组织主要由β相以及少量的α″相组成,而固溶后的合金组织主要由β相以及少量的α相和α″相组成。随着固溶时间延长,合金的晶粒尺寸逐渐增大。固溶处理后的合金在室温下表现出超弹性,其马氏体诱发临界应力σSIM与晶粒尺寸的关系满足Hall-Petch方程。因此,减小合金晶粒尺寸,可有效提高合金的超弹性性能。
