, 2018 A $\textit{regular polygon surface}$ $M$ is a surface graph $( , )$ together with a continuous map $ $ from $ $ into Euclidean 3-space which maps faces to regular Euclidean polygons. When $ $ is homeomorphic to the sphere and the degree of every face of $ $ is five, we prove that $M$ can be realized as the boundary of a union of dodecahedra ...

Engineering “Meso‐Atom” Bonding: Honeycomb‐Network Transitions in Reticular Liquid Crystals
Aggregate, EarlyView.Rod‐like molecules with highly branched carbosilane‐based side‐chains show two modes of aromatic core aggregation controlled by core fluorination. Serving as “meso‐atom bonds,” the locked‐in shift mode due to strong core–core interaction from fluorination replaces the A15‐type 3D cubic liquid crystal network phase by honeycombs with 2D periodicity ...

Periodic skyrmionic textures via conformal cartographic projections
APL PhotonicsWe find periodic skyrmionic textures via conformal cartographic projections that map either an entire spherical parameter space or a hemisphere onto every regular polygon that provides regular tessellations of the plane.

Multistable Composite Laminate Grids as a Design Tool for Soft Reconfigurable Multirotors
Advanced Intelligent Systems, EarlyView.Flexible, lightweight, stable: the reconfigurable multirotor combines stable flight in multiple shapes with low‐energy reconfiguration. Utilizing optimized multistable composites, it achieves self‐locking in open and folded configurations, cutting width‐span by 48% and allowing for safe gap traversal.

Polygonal approximation and energy of smooth knots [PDF]
arXiv, 2003 We establish a fundamental connection between smooth and polygonal knot energies, showing that the Minimum Distance Energy for polygons inscribed in a smooth knot converges to the Moebius Energy of the smooth knot as the polygons converge to the smooth knot.

Tiling Robotics: A New Paradigm of Shape‐Morphing Reconfigurable Robots
Advanced Intelligent Systems, EarlyView.Tiling robotics is a novel paradigm of shape‐morphing reconfigurable robots, defining them as polyform‐inspired machines capable of transforming between at least two polymorphic shapes. Various reconfiguration‐enabling and locomotion mechanisms of tiling robots are comparatively analyzed, with the electromechanical developments, along with a proposed ...
