What is the disadvantage of Graphene/aluminum in aerospace?5 answersThe disadvantage of Graphene/aluminum composites in aerospace lies in the challenge posed by crack propagation. Research indicates that the size and distribution of graphene flakes play a crucial role in the mechanical properties of these composites. When the length of graphene flakes is below 3.35 nm, sub-cracks generated can benefit crack propagation, reducing the mechanical properties of the composite. Additionally, despite the enhancement of properties like surface hardness when graphene is added to aluminum, the composites may still face limitations in terms of wear resistance and hardness, especially in applications where high wear is observed. Therefore, while graphene/aluminum composites offer significant advantages, addressing crack propagation and wear resistance remains a key challenge in their aerospace application.
What is band gap energy?5 answersBand gap energy refers to the energy difference between the valence band and the conduction band in a material, determining its electrical conductivity and optical properties. Various factors influence band gap energy, such as nanoparticle size, ion doping, and interactions like electron-phonon and Coulomb interactions. Studies have shown that band gap energy can be regulated by manipulating these factors. Additionally, in epsilon-near-zero (ENZ) materials, a concept of a radiative energy band gap has been proposed, where the emission of a quantum emitter coupled with an ENZ nanoparticle can be suppressed at specific frequencies, creating an effective energy band gap for radiation. Experimental measurements on semiconductors like TiO2 and silicon crystals have been conducted to determine band gap energy using techniques like diffuse reflectance spectroscopy and transmission measurements.

What are the advantages and disadvantages of each method of producing graphene?4 answersThere are several methods for producing graphene, each with its own advantages and disadvantages. Chemical reduction approaches, such as using harsh chemicals like hydrazine and sodium borohydride, are highly efficient and commonly used for large-scale production of graphene. However, these methods are detrimental to both humans and the environment. An alternative approach is the use of green reducing agents, such as plant extracts and biomolecules, which are more environmentally friendly. Another method is the chemical gas phase method, which produces graphene with high quality and electroconductivity. However, it is costly and has low yield due to the use of expensive substrates like nickel or copper. A physical method involves high temperature shaping, delaminating graphite, and preparing a graphene slurry. This method is simple, low in cost, and can be scaled up for industrial production. Overall, the choice of production method depends on factors such as cost, yield, and environmental impact.
