Why nanomaterials are used?
Aluminium buyers in the US physical metal market have held off on new orders amid fears of a recession triggered by rising inflation and supply chain crises.
Spot aluminium trading on the market has been suspended in recent weeks, according to industry sources, as uncertainty has increased following the outbreak of the conflict between Russia and Ukraine. Even before the war, the aluminium market was suffering from long waiting times and weak demand.
For aluminium buyers, recent poor US economic data have been a big factor in delaying purchases. Data released last month showed that the ISM manufacturing PMI came in at 57.1 in March, below expectations of 59 and down from 58.6 in February, unexpectedly hitting the lowest reading since September 2020. This was mainly due to a slowdown in new orders and nano materials are expected to increase in the future.
What are Nanomaterials?
Nanomaterials can be defined as materials with at least one external size of 1-100nm. The definition given by the European Commission stipulates that at least half of the particles in the quantitative size distribution must have a particle size of 100nm or less.
Because of the ability to generate materials in specific ways to play a specific role, nanomaterials are used across industries, from health care and cosmetics to environmental protection and air purification.
Why nanomaterials are used?
Compared with bulk materials, nanomaterials have the following properties:
Small size effect. The periodic boundary conditions of the crystal are destroyed, and the atomic density near the surface layer of amorphous nanoparticles decreases, which leads to changes in acoustic, optical, electrical, magnetic, thermal and other properties, such as magnetic ordered state to magnetic disordered state, C-conducting phase to normal and so on.
Surface effect. The size of nanoparticles is small, the number of atoms on the surface increases, the surface area and surface tension become larger, and the coordination of atoms is insufficient, so that nanoparticles have high chemical activity and are easy to combine with other atoms.
Quantum size effect. When the particle size decreases to a certain value, the electron energy level near the Fermi level changes from quasi-continuous to discrete energy level. The splitting of energy level spacing will lead to significant differences in magnetic, optical, acoustic, thermal, electrical and C conductivity and macroscopic properties of nanoparticles.
Quantum tunneling effect. Microscopic particles have the ability to penetrate the potential barrier, which is called tunneling effect. It is found that the macroscopic physical quantities such as the magnetization of microparticles and the magnetic flux in quantum coherent devices also have tunneling effect. Moreover, nanomaterials have synergistic effect and quantum coupling effect caused by combination, and many strange properties of nanomaterials can be regulated by external field.

The development of the Russia-Ukraine conflict will continue to dominate the commodity prices such as the nano materials in the future. If the conflict eases or cools, Russia and Ukraine go back to negotiate, commodity prices would fall. However, if the situation between Russia and Ukraine deteriorates further, or evolves into a full-scale war, the price of the nano materials is predicted to see further improvement over the coming days.
