In our experiment, we fixed the sample 9.6 mm away from lens. The whole characterization process is shown in Fig. 9, where a 1.4 kHz repetition rate signal is used. Figure 9 The schematic diagram of the laser setup for the characterization process of nano-antennas. Full size image ...
Iron and chromium were detected in reduced magnetite ore (Fig. 9). The X-ray diffraction of reduced iron (magnetite) reinforcement is shown inFig. 9. 2θ, °d, Å and h k l values of phases found are illustrated inTable 2. Corrosion phase, CrFe was formed in the experiment similar...
1. Wear protective glasses, protective clothing and masks, gloves, and avoid contact with the skin during the experiment. 2. The waste generated after the experiment needs to be stored separately, and handed over to a professional biological waste gas treatment company to avoid environmental pollu...
As the experiment is carried out, a kind of dark green oily liquid will settle to the bottom of the electrolytic cell, and after 2~3H, the whole liquid phase turned green, and the reaction time was not important from the apparent point of view. At the end of the experiment, there was...
After ion cleaning the base was removed from the chamber and the temperature range of heating of it at the finish of the experiment determined. The boundaries of this interval were established from the melting point of the indicators filling the depressions in the base. The temperature of the ...
In the experiment, 50 times long focus objective lens (parameter: 50×/0.35) was used for focusing on the specimens, adjusting the specimen height to complete the focal point, focusing image collected by SunTime130E CMOS color digital camera, excited at the 355 nm line of semiconductor ...
