These imaging conditions substantially reduce the dose to the sample by having a large pixel size and low exposure time, while still achieving high precision in locating atomic columns.
"We need this complex configuration because then we can work around the lack of resolution, both time and spatial (i.e. refresh rate and number of pixels), by having different points of view," said Kajtár.
Each section both of the real and the simulated material is represented by an image having dimension (200times240) pixels in directions (Xtimes Y).
A typical shop-bought digital camera, by comparison, has about 5m pixels.
Each pixel has one returned value defined by the level of corruption present in the pixel.
"Every product that exists out there officially, they have gone over pixel-by-pixel, and for the books, page-by-page.
Each pixel has N support pixels.
Scan results reveal that the region of the powder bed wetted by the nanofluid has substantially higher pixel index values than the dry powder, thus enabling visualization of the sorption profile.
For example, a 1,280-by-1,040 screen actually has 1,280 pixels across and 1,040 down.
Each SAXS data frame had a pixel resolution of 512 × 512 pixels and a pixel size of 383.4 × 383.4 μm.
