The European Union recently approved sweeping new sanctions against Russia, including bans on imports of coal, timber, chemicals, and other nano materials.
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.

Maximo Pacheco, chairman of Codelco, Chile's state copper company, said in a recent interview that he expects copper prices to remain 'very strong in the future,' despite the recent drop. Codelco is the world's largest copper producer.
Copper prices suffered their biggest weekly drop in a year this week on concerns that tightening policy by central banks will dampen global growth and reduce demand for industrial metals. With its wide range of industrial and construction uses, copper prices are often seen as a bellwether of economic activity.
London copper closed at $8,325 a tonne on Friday after touching $8,122.50 a tonne, down 25 per cent from its Peak in March and its lowest level since February 2021. In addition to copper, other industrial metals also fell sharply. Tin, for example, fell nearly 15% at one point on Friday, bringing its losses for the week to about 25%.
"We may be in a temporary short-term turbulence, but what is important is the fundamentals and the balance of supply and demand [currently] looks very favourable for those of us with copper reserves," Mr. Pacheco said. Chile is the world's largest copper producer.
Mr. Pacheco adds that in a world where copper is the best conductor and there are not many new reserves, copper prices look very strong because the future is very favourable for electrification.
