Mechanically Robust and Ion‐Conductive Polyampholyte Elastomers via Dimeric Ionic Bonding
Advanced Materials, EarlyView.This study introduces a new class of polyampholyte ionic elastomers balancing both high mechanical strength and ionic conductivity by utilizing a novel precipitation method to create ionic dimers. The resulting elastomers exhibited strong mechanical performance and excellent ion mobility, making them ideal for applications in flexible electronics ...

Advanced Materials, EarlyView.This work demonstrates a strategy to spatially control supramolecular chirality by leveraging spontaneous twist self‐assembly in liquid crystal materials. It is generated by periodic zigzag line defects that define alternating enantiomeric domains, stabilized by a polymer network. This approach enables precise defect engineering, tunable chirality, and

On the Approximability of the Vertex Cover and Related Problems
, 2010 In this paper we show that the problem of identifying an edge $(i,j)$ in a graph $G$ such that there exists an optimal vertex cover $S$ of $G$ containing exactly one of the nodes $i$ and $j$ is NP-hard. Such an edge is called a weak edge. We then develop a polynomial time approximation algorithm for the vertex cover problem with performance guarantee ...
