The purchasing pace at the demand end of the international thermal coal market continues to slow down and the international thermal coal price continues to decline. Prices for thermal coal at major international ports continued to fall last week as buyers in Europe slowed in recent days for April, coupled with weaker-than-expected import demand from End users in China. According to China Coal Market net monitoring: Australia Newcastle port thermal coal price index was 253 USD/ton, compared with 309.02 USD/ton, down 56.02 USD/ton, down 18.13%. South Africa's Port Richards thermal coal price Index was $264.5 / mt, down the US $62.72 / mt or 19.17% from US $327.22 / mt. The European ARA Tri-port thermal coal price Index was $281.8 / ton. Does the price of thermal coal in major international ports continue to decline to affect the price of the 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.

On August 1, the European Union officially began to implement the "voluntary reduction" agreement on natural gas adopted last month. Under the agreement, EU member states will reduce gas demand by 15 per cent from the average consumption over the past five years through measures of their choice between August 1 this year and March 31 next year.
Several major German cities, such as Berlin, Hanover and Munich, have begun to take measures to reduce energy consumption. Berlin, for example, decided to turn off the lights of more than 200 tourist attractions at night. Berlin's municipal buildings will have indoor temperatures of no more than 20 degrees Celsius between October 1 and March 31 next year, and only nurseries, schools, nursing homes and hospitals can be exempted from energy-saving measures.
Spain's energy conservation plan forces companies, businesses and vehicles to limit air-conditioning temperatures in summer and heating temperatures in winter. The above-mentioned places must limit the air-conditioning temperature to more than 27 degrees Celsius in summer and the heating temperature below 19 degrees Celsius in winter. The plan requires that shop window lighting be turned off at 22:00. The plan also requires the administration to regularly review the heating systems of enterprises in order to avoid energy waste.
