According to foreign media reports, scientists have made breakthroughs in seeking new, sustainable permanent magnets. Most permanent magnets are made from rare earth alloys, but mining and processing such materials can produce toxic by-products, creating ecological challenges associated with rare earth mines and refineries. At the same time, as permanent magnets are a common component of renewable energy, consumer electronics and electric vehicles, their demand is also growing. A team of scientists at the University of Leeds in the UK has made a breakthrough in a new advanced material, and this material may eventually be able to replace rare earth permanent magnets. The researchers developed a hybrid film made of a thin layer of cobalt, which is naturally magnetic and covered with a carbon-buckminster fullerene molecule. The presence of carbon greatly promotes the magnetic energy product of cobalt, which can increase the magnetic energy product 5 times at low temperatures. Magnetic energy product is an indicator to measure the strength of the magnet. The research team observed the increase in magnet strength at minus 195 degrees Celsius, hoping to control the carbon molecules through chemical methods to obtain the same effect at room temperature. Dr. Tim Moorsom, Co-Principal Investigator of the School of Physics and Astronomy at the University of Leeds, said: "This is the first rare-earth magnet comparable to rare-earth permanent magnets such as samarium cobalt. Although so far, we have only achieved this effect at low temperatures, It is hoped that a material similar to this hybrid magnetic material can replace rare earth permanent magnets, thereby reducing damage to the environment. " Although carbon is not magnetic, the combination of carbon molecules and the cobalt surface will produce a magnetic pinning effect, preventing the magnetic direction of the cobalt from changing, even in a strong reverse magnetic field. The interaction on the cobalt surface is the key to the unusually high magnetic energy of this hybrid material. Although it may take a long time to apply such hybrid magnets to wind turbines or electric vehicles, it may be able to be quickly applied to other applications. Co-Principal Investigator Dr. Oscar Cespedes said: "Although it will take a long time for a large number of permanent magnets to be used in room temperature applications such as magnetic storage, molecular coupling can be used to optimize the magnetic properties of thin films." (Yu Qiuyun) Nickel Alloy Pipe is a metal pipe that is made up of an alloy that has primarily nickel and other elements in its composition. The Seamless Nickel Alloy Pipes are usually cold drawn and has less absolute roughness. The seamless nature makes the surface very even which makes the wall thickness uniform along the length of the pipes. There are alloyed nickel pipes and pure alloy pipes. The pure nickel pipes are actually commercially pure and contain about 99% nickel in the composition. The Ni Welded Pipes are good for welding needs. Nickel is very much corrosion resistant and lightweight in nature. These properties of the element are used in various applications. These special steel pipes are used in power generation applications, pharmaceuticals, chemical equipment, sea water equipment, heat exchangers, condensers, pulp and paper industry, off shore oil and gas industries.
