The Cuttlebone Blueprint for Multifunctional Metamaterials: Design Taxonomy, Functional Decoupling, and Future Horizons

Advanced Functional Materials, EarlyView.
Cuttlebone‐inspired metamaterials exploit a septum‐wall architecture to achieve excellent mechanical and functional properties. This review classifies existing designs into direct biomimetic, honeycomb‐type, and strut‐type architectures, summarizes governing design principles, and presents a decoupled design framework for interpreting multiphysical ...

On The Graphs and Their Complements with Prescribed Circumference

Jurnal Ilmu Dasar, 2012
Let Gt(n) be the class of connected graphs on n vertices having the longest cycle of length t and let G ∈ Gt(n). Woodall (1976) determined the maximum number of edges of G.

Commuting graphs and extremal centralizers

Ars Mathematica Contemporanea, 2013
We determine the conditions for matrix centralizers which can guarantee the connectedness of the commuting graph for the full matrix algebra M n ( F ) over an arbitrary field F . It is known that if F is an algebraically closed field and n  ≥ 3 , then the diameter of the commuting graph of M n ( F ) is always equal to four.

Geometrically Tunable Scaffold‐Free Muscle Bioconstructs for Treating Volumetric Muscle Loss

Advanced Healthcare Materials, EarlyView.
Volumetric muscle loss is associated with traumatic muscle resulting in permanent functional impairment. Mold‐based, scaffold‐free, high‐density muscle tissue bioconstructs are developed in customizable geometric shapes and sizes. The transplanted rectangular solid‐shaped muscle bioconstructs improved muscle force recovery and tissue regeneration in ...

Hybrid Nanofibers for Multimodal Accelerated Wound Healing

Advanced Healthcare Materials, EarlyView.
Fabrication of wound healing scaffolds based on biocompatible nanofibers. Nanofibers offering high surface area, flexibility, and biocompatibility significantly improved the healing outcome in vivo. Histological, immunological, and anti‐inflammatory markers are noticeably better in treated wounds.

Dynamic Modulation of the Microenvironment Promotes Functional Maturation of Engineered Tissues

Advanced Healthcare Materials, EarlyView.
Engineered tissues lack the dynamic microenvironment of native tissues. A biocompatible, diffusible small molecule to dynamically modulate tissue microenvironments during maturation is used. Timing‐dependent modulation yields distinct outcomes, producing thicker, more native‐like blood vessels, stronger and more mature cardiac tissues, and optimized ...

Extremal graphs without 4-cycles

Journal of Combinatorial Theory, Series B, 2013
We prove an upper bound for the number of edges a C4-free graph on q^2 + q vertices can contain for q even. This upper bound is achieved whenever there is an orthogonal polarity graph of a plane of even order q.

Electro‐Stimulated Graphene‐Polymer Nanocomposites Enable Wearable Patches With Feedback‐Controlled Drug Release

Advanced Healthcare Materials, EarlyView.
xx xx. ABSTRACT Stimuli‐responsive nanomaterials capable of spatiotemporal control over drug release are of nanocomposite patch (“e‐Medi‐Patch”) engineered from biodegradable polycaprolactone (PCL), graphene nanoplatelets, and a redox‐active therapeutic, niclosamide. The hierarchical composite integrates π‐π interactions between aromatic drug molecules

Extremal graph problems with symmetrical extremal graphs. Additional chromatic conditions

Discrete Mathematics, 1974
AbstractThe main result of this paper is that for a special, but rather wide class of “sample graphs”, the extremal graphs, i.e. the graphs of n vertices without subgraphs isomorphic to the sample graph and having maximum number of edges under this condition, have very simple and symmetric structure.
