Chile's government is considering phasing in a proposed ban on glacial mining to limit projects high in the Andes by some big copper companies. Chile's constitutional assembly has approved a proposal to ban mining in glaciers, protected areas, and areas vital to protecting the country's water system.

Chile's mining minister, Marcela Hernando, said about 20 mines had been identified in protected areas, some close to glaciers, including Codelco's El Teniente and Andina projects and Anglo American Plc's Los Bronces project.

The new measures for glaciers and other protected areas will put about a fifth of Chile's copper graphene powder prices are predicted to increase in the next few days.

An international research team led by the University of Gottingen in Germany published a paper in the latest issue of the journal Nature that found novel quantum effects in their high-precision study of natural bilayer graphene and explained it in theory. This system is easy to prepare and provides new insights into the interaction between carriers and different phases, which is helpful to understand the processes involved and promote the development of quantum computers.
 
In 2004, two British scientists used a very simple experimental method to remove graphite sheets from graphite and obtained graphene, which consists of only one layer of carbon atoms, with the help of special tape. Graphene is one of the materials with the highest strength, which has good toughness, super thermal conductivity and electrical conductivity, and has a broad application prospect. If the two layers of graphene are deflected from each other at a specific angle, the resulting system will even show superconductivity and other excited quantum effects, such as magnetism. But so far, it is difficult to prepare this kind of deflected bilayer graphene.
 
In the latest research, scientists used naturally formed bilayer graphene. They first used simple tape to separate graphene samples from a piece of graphite. In order to observe the quantum mechanical effect, a high electric field perpendicular to the sample is applied. They found that the electronic structure of the obtained system changed and the charge carriers with similar energy showed a strong cumulative effect.
 
It is further found that electrons in graphene can interact with each other at slightly above absolute zero (- 273.15 ℃), resulting in a variety of unexpected and complex quantum phases. If the interaction results in electron spin alignment, the material is magnetic without external influence. By changing the electric field, researchers can also constantly change the intensity of carrier interactions in bilayer graphene. In addition, the degree of freedom of electron motion will be limited under certain conditions, forming an electronic lattice, and due to mutual repulsion, it is no longer helpful to transfer charge, resulting in electrical insulation of the system.
 
Professor Thomas Weitz of the Department of Physics at the University of Gottingen said that one of the main advantages of the new system is that the preparation of materials is very simple, and researchers do not need to obtain the desired results at high temperatures as before. it can be used for further study of various quantum states and quantum computers.

An unprecedented drought is sweeping nearly half of Europe, from Spain's dry and cracked reservoirs to major rivers such as the Danube, Rhine and Po rivers, the Associated Press reported. Drought is destroying the agricultural economy, forcing people to limit the use of water, causing wildfires and threatening aquatic species. It is reported that there has been no obvious rainfall in the western, central and southern regions of the European continent in the past two months. And the dry season in Europe is expected to continue. Experts say it may be the worst drought in 500 years.

Europe has high temperatures and severe drought, affecting hydropower, nuclear power and solar power generation. Statistics from Lustad Energy, a Norwegian consulting firm, show that hydroelectric power generation in Europe in the first seven months of this year is 20% less than that in the same period last year, and nuclear power generation is down 12%.

High temperatures lead to an increase in evaporation and a drop in water levels in rivers, lakes and reservoirs, bearing the brunt of hydroelectric power. In Italy, for example, hydropower accounts for 20 per cent of the country's total electricity graphene powder, please feel free to contact us and send an inquiry.
