What were these two types of structures? In electron micrographs ... like network is quite flexible and can be organized in a planar sheet. In contrast, the maxicircle catenanes are organized ...

Ideally, non-planar 3D printing is done using a somewhat pointy nozzle, as flat nozzles tend to dig into the previously printed material and easily get entangled in infill structures. Generally ...

These are known as Z-type ligands ... the square-planar geometry is more common for the 2+ oxidation state of nickel, spectroscopic analysis confirmed this unusual electronic structure in this ...
