Ptychog. X-ray microscopy is an ideal tool to observe chem. processes under in situ conditions. Chem. reactors, however, are often thicker than the depth of field, limiting the lateral spatial resolution in projection images. To overcome this limit and reach higher lateral spatial resolution, wave propagation within the sample environment has to be taken into account. Here, we demonstrate this effect recording a ptychog. projection of copper(I) oxide nanocubes grown on two sides of a polyimide foil. Reconstructing the nanocubes using the conventional ptychog. model shows the limitation in the achieved resolution due to the thickness of the foil. Whereas, utilizing a multi-slice approach unambiguously separates two sharper reconstructions of nanocubes on both sides of the foil. Moreover, we illustrate how ptychog. multi-slice reconstructions are crucial for high-quality imaging of chem. processes by ex situ studying copper(I) oxide nanocubes grown on the walls of a liquid cell. In the experiment, the researchers used Bis(acetylacetone)copper(cas: 13395-16-9Reference of Bis(acetylacetone)copper)
Bis(acetylacetone)copper(cas: 13395-16-9) is used as PVC stabilizer, and curing agents for epoxy resins, acrylic adhesives and silicone rubbers. It is also used as solvents, lubricant additives, paint drier, and pesticides.Reference of Bis(acetylacetone)copper
