Thermal Expansion of Hybrid Chiral Mechanical Metamaterial with Patterned Bi‐Strips

High Density Polyethylene Composites Reinforced with Hybrid Inorganic Fillers: Morphology, Mechanical and Thermal Expansion Performance

The effect of individual and combined talc and glass fibers (GFs) on mechanical and thermal expansion performance of the filled high density polyethylene (HDPE) composites was studied. Several published models were adapted to fit the measured tensile modulus and strength of various composite systems. It was shown that the use of silane-modified GFs had a much larger effect in improving mechanic...

Lightweight Mechanical Metamaterials with Tunable Negative Thermal Expansion.

Ice floating on water is a great manifestation of negative thermal expansion (NTE) in nature. The limited examples of natural materials possessing NTE have stimulated research on engineered structures. Previous studies on NTE structures were mostly focused on theoretical design with limited experimental demonstration in two-dimensional planar geometries. In this work, aided with multimaterial p...

Chiral waves in metamaterial medium

In this paper we will present a brief overview of electromagnetic properties of the media with negative permittivity and permeability, and then we will discuss some ideas about possible applications of these materials. In this work we discuss the chiral waves in metamaterial media. Here we study the conditions for strong chirality which can give situations of chiral metamaterial and we propose ...

Chiral Waves in Graphene Medium and Optical Simulation with Metamaterial

Zero thermal expansion in a nanostructured inorganic-organic hybrid crystal.

There are very few materials that exhibit zero thermal expansion (ZTE), and of these even fewer are appropriate for electronic and optoelectronic applications. We find that a multifunctional crystalline hybrid inorganic-organic semiconductor, beta-ZnTe(en)(0.5) (en denotes ethylenediamine), shows uniaxial ZTE in a very broad temperature range of 4-400 K, and concurrently possesses superior elec...
