Aug 21, 2017 · Figure 1b shows a typical HRTEM image of a Cu 2 O/Cu interface generated by the oxidation of a Cu-faceted edge. In situ TEM observations of the Cu 2 O/Cu interface dynamics are made...

Jan 20, 2016 · Figure 1 shows a series of HRTEM images, which reveal a typical annealing process of a Cu nanoparticle on graphite substrate at 1073 K. (see a movie given in Supplementary Movie 1). Note that...

Figure 4 shows the high-resolution (HR) TEM images of the oxidized Cu surfaces, which further confirm this pressure-dependent orientation of oxide nuclei.

The high-resolution transmission electron microscope (HRTEM) image of CuO-Cu 2 O in Fig. 4b shows the presence of two different interplanar distances of 0.25 and 0.24 nm, corre- sponding...

Apr 1, 2020 · The atomic structure model and corresponding simulated HRTEM image (insets in Fig. 4 D) are matched with HRTEM image. Starting from a flat surface, pile-up of molecules along the normal direction on top of the (001) surface is preferred rather than in-plane lateral growth.

Oct 16, 2009 · The HRTEM image of a Cu nanoparticle (30 nm) in sample D after its exposure to air in Fig. 3 shows that the surface of the freshly prepared Cu nanoparticles can be oxidized to Cu 2 O quickly, though the Cu 2 O layer is not homogeneous. The colloid of sample D remains dark red for at least 3 months, indicating that the full oxidization of ...

John et al. (2021) reported the TEM micrographs of CuO-NPs from marine bacteria and reported the synthesis of monodispersed, spherical/ovoidal NPs of 10 nm-70 nm size with~40 nm average size....

Oct 11, 2019 · High-resolution transmission electron microscopy (TEM) is utilized to investigate the structure of Cu precipitates thermally formed in a high-strength low-alloy (HSLA) steel. The Cu precipitates were generally formed from solid solution and at the crystallographic defects such as martensite lath boundaries and dislocations.

Apr 1, 2022 · In situ electron irradiation using high-resolution transmission electron microscopy (HRTEM) was performed to visualize the Frank loop evolution in aluminum–copper (Al–Cu) alloy with an atomic-scale spatial resolution of 0.12 nm.

Feb 1, 2021 · In this paper, a ternary composite of Cu/Cu 2 O@C, in which a Cu/Cu 2 O heterojunctions with “head to head” combination fashion uniformly disperse in the octahedral carbon framework, is in situ generated by treating a copper-metal-organic framework (Cu-MOF) under a relatively mild temperature.
