The contrast-to-gradient (CG) method has been proposed previously for the evaluation of image resolution in scanning electron microscopy (SEM). In the CG algorithm, the image to be evaluated is gradually reduced to form the 1/r-reduced imag...
Spectral restoration and energy resolution improvement of electron energy-loss spectra by Pixon reconstruction: I. Principle and test examples [0.03%]
基于Pixon重建的电子能量损失谱的谱学恢复及其能量分辨率的改善(I):原理及示例研究

The visibility of a Si crystalline nanoparticle of diameter 2 nm embedded in an amorphous SiO(2) layer is evaluated quantitatively by multislice calculation. The visibility depends on the crystal orientation of the Si nanoparticle, the thic...
The wrap-around problem and optimal padding in the exit wave reconstruction using HRTEM images [0.03%]
利用HRTEM图像重建出口波函数中的周期性外推问题和最优填充问题
F Lin,F R Chen,Q Chen et al.
F Lin et al.
A free fast Fourier transform software FFTW (www.fftw.org) is used in the exit wave reconstruction and shown to be able to handle images of any size effectively. The wrap-around problem commonly encountered in the exit wave reconstruction i...
A modified back-etch method for preparation of plan-view high-resolution transmission electron microscopy samples [0.03%]

Bo Yao,Rumyana V Petrova,Richard R Vanfleet et al.
Bo Yao et al.
A modified back-etch method is described that has been successfully used to prepare samples of thin films and nanoparticles on Si wafer substrates for examination by high-resolution transmission electron microscopy (HRTEM). This process inc...
AFM and TEM observations of alpha-helix to beta-sheet conformational change occurring on carbon nanotubes [0.03%]

Yukihiro Sugiyama et al.
Bacteriorhodopsin (BR), which is rich in alpha-helical structure, was spread onto water with single-wall carbon nanotubes (SCNTs). After a Langmuir trough was used to apply compressive surface pressure to maintain the alpha-helices monolaye...
Changes of aquaporin 5-distribution during release and reaccumulation of secretory granules in isoproterenol-treated mouse parotid gland [0.03%]
异丙肾上腺素处理的小鼠颌下腺分泌颗粒释放和重新积累过程中Aquaporin 5的分布变化研究

Toshiyuki Matsuzaki et al.
Water channel aquaporin 5 (AQP5) is present in the apical membrane of the salivary gland acinar cells. We examined changes of AQP5-distribution during the fusion process of secretory granule membranes into the apical membrane and subsequent...
Immunocytochemical localization of glutathione precursors in plant cells [0.03%]
植物细胞中谷胱甘肽前体的免疫细胞化学定位
