Optimum high temperature strength of two-dimensional nanocomposites

High-strength, healable, supramolecular polymer nanocomposites.

A supramolecular polymer blend, formed via π-π interactions between a π-electron rich pyrenyl end-capped oligomer and a chain-folding oligomer containing pairs of π-electron poor naphthalene-diimide (NDI) units, has been reinforced with cellulose nanocrystals (CNCs) to afford a healable nanocomposite material. Nanocomposites with varying weight percentage of CNCs (from 1.25 to 20.0 wt %) within...

High temperature superconductivity from the two-dimensional semiconductors without magnetism

We examine the possibility of high temperature superconductivity from two-dimensional semiconductor without antiferromagnetic fluctuations. The weak coupling BCS theory is applied, especially where the Fermi level is near the bottom of the conduction band. Due to screening, the attractive interaction is local in k-space. The density of states(DOS) does not have a peak near the bottom of the ban...

Synthesis and Electrochemical Properties of Two-Dimensional RGO/Ti3C2Tx Nanocomposites

MXene is a new type of two-dimensional layered material. Herein, a GO/Ti₃C₂Tx nanocomposite was prepared by a simple liquid phase method, and the obtained GO/Ti₃C₂Tx was transformed into RGO/Ti₃C₂Tx under high temperature with Ar/H2. The prepared samples were characterized using X-ray diffraction (XRD), Raman measurement, scanning electron microscopy (SEM), energy disperse spectroscopy (EDS), a...

Experimental investigation of the strength of glass fiber-reinforced concrete exposed to high temperature

This study investigated the effects of high temperature exposure on the compressive, tensile, and flexural strengths of concrete containing glass fiber. A total of 108 cubic specimens (150 mm × 150 mm × 150 mm), cylindrical specimens (300 mm × 150 mm), and prismatic specimens (500 mm × 150 mm × 150 mm) were prepared for compressive, tensile, and flexural strength testing, respectively. The spec...
