Silicon nanotube - Wikipedia

A silicon nanotube charged with hydrogen delivers energy and in the process leaves residual water, ethanol, silicon and sand. However, as hydrogen production requires considerable energy, this is only a proposed method of storing energy, not producing it. Silicon nanotubes and silicon nanowires can be used in lithium-ion batteries. Conventional

Microwave Irradiation Assisted Synthesis of Silicon

Conventional methods for the synthesis of silicon carbide were well studied and these methods included carbothermal reduction, mechanical milling, sol-gel process and others. However, conventional methods have limitations such as high energy consumption, presence of impurities and long reaction times. In this paper, microwave heating was applied for the first time for the synthesis of silicon

The 10 Strongest Materials Known To Man

Silicon carbide. Brief introduction. Silicon carbide is a natural mineral in nature, or it is made from quartz sand, petroleum coke (or coal coke), wood chips and other raw materials by smelting at high temperature in a resistive furnace. Silicon carbide is hard with a Mohs hardness of 9.5, which is second only to the world''s hardest diamond.

Specific strength - Wikipedia

The specific strength is a material''s strength (force per unit area at failure) divided by its density. It is also known as the strength-to-weight ratio or strength/weight ratio or strength-to-mass ratio. In fiber or textile appliions, tenacity is the usual measure of specific strength.

Effect of multi-walled carbon nanotubes and silicon

AbstractIn this study, the deleterious influence of hot deionized water on adhesively bonded joints was reduced with silicon carbide (SiC) nanoparticles and multi-walled carbon nanotubes (MWCNTs). A gravimetric method was used to study the kinetics of water ingress into the neat and nanocomposite epoxy adhesives. Then, joints were manufactured using the same neat and nanocomposite adhesives

Silicon Carbide Nanotubes Functionalized by Transition

Single-walled carbon nanotubes (SWCNTs) functionalized by metals have great potential for appliions in hydrogen storage, chemical sensors, and nanodevices. Because the exterior of single-walled silicon carbide (SiC) nanotubes has a higher reactivity than that of SWCNTs, it is highly desirable to investigate the functionalization of single-walled SiC nanotubes by transition metal atoms.
