A New Method for Size Estimation of Cu Nano-precipitates in Fe Based on Positron Quantum-dot Confinement
Dimensional Atom Probe)は,微細な Cuナノ析出物の検 出が可能であるが,それでも位置分解能の限界に近い直 径サブナノメートルのCu析出物の寸法評価は依然とし て難しい。 最近我々は,「陽電子量子ドット閉じ込め」現象を発見 し,これを利用することによって,従来の手法では観察困 難だった直径サブナノ ナノメートルのCu析出物を非常 に敏感に検出し,観察できることを示した 。本研究で は,これを基礎にして,Fe中Cu析出物に関する新しい寸 法評価法を開発した。Cu(サブ)ナノ析出物中では,量 子力学の基本原理である位置・運動量の不確定性関係か ら,析出物の寸法(実空間)に反比例した電子・陽電子対 の運動量分布の“ぼけ”(スメアリング)が生じる。これ を陽電子消滅2次元角相関 (2D-ACAR: Two-Dimensional Angular Correlation ...
متن کامل3D ChemiSTEMTM Tomography of Nano-scale Precipitates in High Entropy Alloys
Electron tomography is a three-dimensional technique well suited for characterizing fine-scale microstructural features on the order of 10-100 nm. Typically performed in a transmission electron microscope (TEM), it relies on successive image acquisition at multiple sample tilts. Images may be formed through various techniques including conventional and scanning transmission electron microscopy ...
متن کاملNano Weapons Functioning on the Nano Scale
The nano-microcapsules drug delivery system is currently a promising method for the treatment of many types of diseases, particularly tumors. However, the drug delivery efficiency does not reach a satisfactory level to meet treatment demands. Therefore, the effectiveness of delivery needs to be improved. Based on the alterations in the structure and modification of nano-microcapsules, ultrasoun...
متن کاملStructural studies on the interaction of nano-SiO2 with lysozyme
The interaction between nano-SiO2 and lysozyme was investigated by the method of UV-Visible detection and fluorescence spectroscopic techniques. The thermal denaturation of lysozyme has been investigated in the presence and absence of nano-SiO2 over the temperature range (293-373) K in different buffers and pH values, using temperature scanning spectroscopy. The presence of nano-SiO2 caused th...
