Round magnets, also named disc magnets, are thin flat circular magnets where the thickness does not exceed the diameter. Round Magnet,Ndfeb Round Magnet,N35 Round Magnet,Neodymium Ndfeb Big Round Magnet Jinyu Magnet (Ningbo) Co., Ltd. , https://www.magnetbonwin.com
They are the most commonly used magnet shape and the most versatile.
They are used in holding applications where a hole is drilled and the magnet is recessed into the hole.
They are commonly used with cup assemblies to increase their holding strength.
Neodymium disc magnets are incredibly versatile and have superb strength for their size. They`re used in many commercial applications including modular retail displays and point of sale stands for holding panels to a steel framework and many new packaging designs use them cleverly trapped behind layers of cardboard to provide invisible closing mechanisms.
Round magnets have a diameter greater than thickness, and are available in sizes approx 3mm up to approx 100mm diameter. Pull strengths begin at around 250g and can reach up to 262kg!
Wraping radioactive materials into diamond nuclear waste into a "diamond battery"
According to a report on the 27th of the University of Bristol, the research team of physicists and chemists has developed a new technology that can produce nuclear energy batteries from nuclear waste. They wrapped the radioactive material into the diamond and placed it near the source to produce a small amount of current. New research is expected to solve the long-standing problem of nuclear waste disposal and battery life.
The research team demonstrated the prototype of the "diamond battery" made of the radioactive element nickel-63 in the annual "Change the World" idea at the Cabot Institute. Unlike most power generation technologies that require energy to drive a magnet through a wire to generate a current, a "diamond battery" can generate current only by approaching the source. Tom Scott, a researcher and professor of materials at the school's interface analysis center, explains that there is no need to drive any particles, no waste emissions, and no regular maintenance. Our new batteries can generate electricity directly, turning nuclear waste into clean energy.
There are currently about 95,000 tons of graphite blocks containing radioactive carbon-14 in the UK, and the research team is studying how to further increase the efficiency of the "diamond battery" by adding carbon-14. They found that carbon-14 is mainly concentrated on the surface of the graphite block of the nuclear power plant reactor, so it is easy to extract, and the extracted carbon-14 is wrapped into the diamond to make a new nuclear energy battery. Neil Fox, a professor of chemistry at the school, believes that short-range radiation from carbon-14 can be absorbed by almost all solid materials. Once absorbed by the body or in direct contact with the skin, it will cause great harm. But now it is wrapped in the world's hardest substance - diamonds, carbon-14 has become an inexhaustible energy "gem".
Although the production capacity is too low compared to other battery technologies, the service life of the “diamond battery†will revolutionize the power generation device: carbon-14 consumes 50% of its energy when it is used in 5730, which is especially suitable for those inconvenient. Low-energy devices that charge or replace batteries, such as pacemakers, satellites, high-altitude drones, and even spacecraft.
Making nuclear waste into a battery has indeed solved the problem of spent fuel disposal that has plagued the nuclear industry. It has also provided a clean energy that can be said to be "sustainable". It can be described as two birds. However, the radiation material should be wrapped into diamonds to play a role, it must be costly; and the power it provides is relatively limited. If it is to be widely applied, the issue of nuclear proliferation is also a headache. In short, the research team's idea does "change the world", but if you really use it, or even walk into people's lives, I am afraid it will be "drained and long."
