Planar tetracoordinate lithium in LiLi4F4+ cluster
The Journal of Chemical PhysicsOver the past 50 years, planar tetracoordinate carbons have attracted significant attention for challenging the classical tetrahedral bonding model proposed by van’t Hoff and Le Bel. While the planar framework has been extended to all other first-row elements beyond carbon, stable ptLi (lithium) compounds remain notably missing.

Hierarchical Planar Correlation Clustering for Cell Segmentation
2015We introduce a novel algorithm for hierarchical clustering on planar graphs we call “Hierarchical Greedy Planar Correlation Clustering” (HGPCC). We formulate hierarchical image segmentation as an ultrametric rounding problem on a superpixel graph where there are edges between superpixels that are adjacent in the image.
