Accompanying Structural Transformations in Polarity Switching of Heavily Doped Conjugated Polymers

Advanced Materials, EarlyView.
The polarity switching of heavily doped p‐type conjugated polymers (CPs) toward environmentally stable electron‐rich thin films is demonstrated. Multiscale analyses, incorporating spectroscopic, electrochemical, and scattering techniques, reveal structural and chemical transformations induced by excessive doping with AuCl3.

Locally $s$-distance transitive graphs [PDF]

, 2010
We give a unified approach to analysing, for each positive integer $s$, a class of finite connected graphs that contains all the distance transitive graphs as well as the locally $s$-arc transitive graphs of diameter at least $s$. A graph is in the class

Cosmological Constant in LQG Vertex Amplitude

, 2011
A new q-deformation of the Euclidean EPRL/FK vertex amplitude is proposed by using the evaluation of the Vassiliev invariant associated with a 4-simplex graph (related to two copies of quantum SU(2) group at different roots of unity) embedded in a 3 ...

Spatial Control of Chiral Self‐Assembly and Lithographic Applications in Liquid Crystal Polymer Network

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

Sum-edge characteristic polynomials of graphs

Journal of Taibah University for Science, 2019
Modelling a chemical compound by a (molecular) graph helps us to obtain some required information about the chemical and physical properties of the corresponding molecular structure.

Drastic Mechanochromic Luminescence Through Fluorescence–Phosphorescence Switching in a Heavy‐Atom‐Free Organoboron Compound

Advanced Optical Materials, EarlyView.
A new heavy‐atom‐free, donor–acceptor‐type organoboron luminophore has been synthesized, which exhibits red room‐temperature phosphorescence (RTP) in the crystalline state. Furthermore, the amorphous solid generated by grinding shows green thermally activated delayed fluorescence (TADF), displaying distinct mechanochromic luminescence (MCL) through ...

Limits of Ordered Graphs and their Applications

, 2019
The emerging theory of graph limits exhibits an analytic perspective on graphs, showing that many important concepts and tools in graph theory and its applications can be described more naturally (and sometimes proved more easily) in analytic language ...

Formation Control of Multi‐Agent System with Local Interaction and Artificial Potential Field

Advanced Robotics Research, EarlyView.
This article proposes a local interaction‐based formation control method for Multi‐Agent system, integrating consensus and leader‐follower strategies with a stress response mechanism—artificial potential field to reduce communication overhead and enable obstacle avoidance. Experimental results on triangular, square, and hexagonal formations confirm its

The Morphological, Behavioral, and Transcriptomic Life Cycle of Anthrobots

Advanced Science, EarlyView.
DNA is thought to determine shape, behavior, and lifespan, with developmental plasticity reserved for stem cells, embryos, and species like amphibia. How much morphogenetic plasticity do adult somatic human cells exhibit? Anthrobots are a self‐organizing, motile synthetic living construct made of genetically normal human epithelial cells.

Generalized Zagreb index of some dendrimer structures

Universal Journal of Mathematics and Applications, 2018
Chemical graph theory, is a branch of mathematical chemistry which deals with the nontrivial applications of graph theory to solve molecular problem. A chemical graph is represent a molecule by considering the atoms as the vertices and bonds between them
