High-aspect ratio micro- and nano-structures have been used for the production of a variety of applications. In this paper, we describe a simple and cost-effective approach to fabricate an arrayed microarchitecture with an ultra-high aspect ratio using soft materials. The shapes and sizes of the honeycomb structure can be easily modulated by changing the dimensions and position of the base moul...

This paper describes a new concept of an active honeycomb structure for morphing wingtip applications based on tubular inflatable systems and an auxetic cellular structure. A work-energy model to predict the output honeycomb displacement versus input pressure is developed together with a finite element formulation, and the results are compared with the data obtained from a small-scale example o...

We investigated the mechanical behavior of two-dimensional hierarchical honeycomb structures using analytical, numerical and experimental methods. Hierarchical honeycombs are constructed by replacing every three-edge vertex of a regular hexagonal lattice with a smaller hexagon. Repeating this process builds a fractal-appearing structure. The stiffness and strength of this structure is controlle...

BACKGROUND A honeycomb-like structure in the coronary artery is rarely diagnosed by intracoronary ultrasound or optical coherence tomography. Further, its structural mechanisms and response to interventional therapy remain unknown. CASE PRESENTATION A 59-year-old Japanese man was referred to our hospital because of acute decompensated heart failure with rapid atrial fibrillation. After receiv...

A microfluidic approach to a honeycomb-structure material based on the synergistic effects of polymer rapid precipitation, double emulsion templating, and internal effervescent salt decomposition is reported. The delicate honeycomb structure exhibits unique characteristics with an external nanopore membrane and internal multiple cavities. The biological functionality of the artificial structure...

The early growth stage and growth evolution to a unique gold (Au) honeycomb nano-network on Si(111)7×7 at room temperature have been studied by direct filled-state and empty-state imaging by scanning tunneling microscopy (STM). The gold honeycomb structure is made up of six triangular gold clusters around the corner hole interconnected to one another in the dimer rows of the Si(111)7×7 substrate.

Because of the complex nature of structural characteristics, damage detection in honeycomb sandwich structures inherently carries many challenges. In the study, effects of debonding on leaky guided wave propagation in honeycomb sandwich structures are first studied by using the finite element method. A surface-bonded piezoelectric wafer actuator/sensor network is used for elastic-guided wave pr...

In this paper, we introduce a new subdivision scheme which we call honeycomb subdivision. After one iteration of the scheme each vertex becomes exactly 3-valent and with consecutive applications regular regions strongly resembles a honeycomb. This scheme can be considered as a dual for triangle schemes. The major advantage of the new scheme is that it creates a natural looking mesh structure.

We illustrate a new approach toward the synthesis of a porous supramolecular honeycomb based on triptycene. A coordination polymer has been prepared where the triptycene groups are linked through triptycenesemiquinonediimine platinum complexes, but the product is disordered rather than the intended honeycomb structure. A model platinum complex and its (15)N-labeled isotopomer have been prepared...
