See what you will probably never see in reality, thanks to the PCOD

Two-dimensional B2O3 models (not DFT-optimized) as predicted by GRINSP

They can be porous too...

Construction of these B2O3 models (3D, 2D, 1D and 0D) described in 2005 and 2010 in refs. [1 and 8] - BO3 triangles interconnected exclusively by corner-sharing. See other works in a 2012 paper and in a 2016 thesis. Data from the 2009 (766 models) and 2010 (5118 models) PCOD updates.

Not exhaustive list (more will be added during the next weeks, maybe)...

The following shows that GRINSP may be used for the automatic building of decorative ceramic plaques for bathrooms or swimming pools ;-).
