Steinitz theorems for simple orthogonal polyhedra
Journal of Computational Geometry, 2014 We define a simple orthogonal polyhedron to be a three-dimensional polyhedron with the topology of a sphere in which three mutually-perpendicular edges meet at each vertex.By analogy to Steinitz's theorem characterizing the graphs of convex polyhedra, we

Disordered Rocksalts as High‐Energy and Earth‐Abundant Li‐Ion Cathodes
Advanced Materials, EarlyView.Disordered rocksalts with lithium excess (DRX) offer a new direction in Li‐ion cathode design beyond conventional Ni‐ and Co‐based materials. This review highlights the design principles, synthesis strategies, and performance optimization of DRX oxides and oxyfluorides for energy‐dense, sustainable batteries using Earth‐abundant transition metals and ...

Faceted polymersomes: a sphere-to-polyhedron shape transformation
Chemical Science, 2019 We uncover how our polymersomes facet through a sphere-to-polyhedron shape transformation pathway that is driven by perylene aggregation confined within a topologically spherical polymersome shell.

An approach for line clipping against a convex polyhedron
Ruhuna Journal of Science, 2016 Line clipping operation is a bottleneck in most of computer graphics applications. There are situations when millions of line segments need to be clipped against convex polyhedrons with millions of facets.

Capillary‐Driven 3D Open Fluidic Networks for Versatile Continuous Flow Manipulation
Advanced Materials, EarlyView.The capillary‐driven 3D open fluidic networks (OFNs), composed of connected polyhedral frames, enable precise, programmable, and versatile manipulation of unary, binary, and multiple continuous flows in both spatial and temporal dimensions. OFNs represent a significant leap beyond conventional microfluidics, unlocking new possibilities for selective ...
