Bm ultrascan ccd camera

One drop of the powder suspended in ethanol was deposited on a standard TEM copper grid coated with an amorphous carbon film. After the grid went completely dry it was ready to put into the microscope.
Investigations were conducted on the FEI Titan Cubed 80–300 TEM with an accelerating voltage of 300 kV and the point resolution of 130 pm. The overview images were registered in bright-field TEM mode for magnifications ranging from 9.800x to 55.000x. For the purpose of high-resolution imaging magnifications from 145.000x − 380.000x range were used. In both cases, the images were obtained with the Gatan BM-Ultrascan CCD camera. STEM (scanning mode) images were acquired with the use of the HAADF detector which registers strongly scattered electrons. The in situ EDAX spectrometer was used for the analysis of the specimen's elemental composition.

The AuBSA-Fe samples were measured by HR-TEM Titan G2 60–300 (FEI, Hillsboro, OR, USA) with an image corrector at an accelerating voltage of 300 kV. Images were taken with a BM UltraScan CCD camera (Gatan, Pleasanton, CA, USA). Energy Dispersive Spectrometry (EDS) was performed in STEM mode by a Super-X system with four silicon drift detectors (Bruker, Billerica, MA, USA). STEM images were taken with an HAADF detector 3000 (Fishione, Export, PA, USA).
