According to the "Nature" magazine website and the American Physicist Organization Network on March 22 (Beijing time), the world's largest laser, the so-called "artificial sun" of the United States National Ignition Equipment (NIF) recently launched a laser After the last focusing lens, it reached 2.03 megajoules. At the same time it broke the record, it became the world's first 2 mega-joule energy ultraviolet laser. The 192 laser beams finally projected to the target chamber shot 1.875 megajoules ( MJ) energy. Despite exceeding its 1.8 megajoules of design capability, the laser system did not suffer excess damage. Located at the Lawrence Livermore National Laboratory in California, NIF has been unable to challenge its world's largest laser fusion machine since its completion in May 2009. It can produce heat and force similar to that of the star's inner core, and is designed to enable the United States to maintain nuclear deterrence without the need for nuclear tests. However, in addition to military use and exploration of the universe, the dream of a great clean energy is also shared. Ultra-high-powered UV lasers focus on tiny hydrogen fuel balls, which are expected to enable humans to obtain nuclear fusion energy in the laboratory. A kind of clean energy that is almost "exhausted inexhaustible." This is something that we couldn't think of before. In October 2010, NIF completed its first comprehensive ignition experiment. The laser system emitted 1 megajoules of laser energy into the cryogenic chamber, which is more than 30 times the laser experimental energy of the University of Rochester in the world. In recent days, it broke its own record again. According to the director of the NIF, Ed Moses, the 2.03 mega-joy laser has an optical loss of 1.875 megajoules in the center of the target chamber. Laser component damage is less than model testing, and the laser can be re-emitted after 36 hours. A record hit. However, this experiment is only a proof test, the target target room is empty, but its significance is still a milestone in the exploration of fusion energy. The researchers refused to disclose when this level of laser would be directed toward a fuel-laden fusion tank. In the real "ignition", the intense laser is directed to the fuel pellets, and the interior of the fusion capsule is instantaneously compressed, causing the fuel pellet to burst and causing the nuclear fusion reaction of the fuel to generate enormous energy. NIF researchers have pointed out that this laser is the first facility to break through the balance point - in the fusion reaction, the energy generated is greater than the energy consumed to achieve "energy gain" to complete fusion ignition. Geekosystem, a geek website, commented on the incident, saying that although humans currently have a long way to go to have a "death star" ("Star Wars" superpower capable of destroying a planet), 2 The realization of the "firing" of the mega-laser laser is still a step closer to the realization of the technological development to achieve the change of controlled nuclear accumulation.
Practical disposable transfer pipettes, made from natural low density polyethylene (LDPE). The transfer pipet is simple and safe to use with a long shelf life; no issues with broken glass, cracked or loose bulbs. Additional advantage is that with the single piece design lager amount can be transferred by allowing fluids in the bulb. These plastic transfer pipettes are ideal for transferring small amounts of fluids for microscopy sample preparations or to prepare mixtures or staining solutions. The extra fine tip enables transferring minute amount of fluids. These cost-efficient plastic transfer pipettes are disposable and intended for one-time use. Ideal for educational and research environments. Can be used for fluids up to 70°C, please take care to protect the fingers squeezing the bulb. Available in six sizes/styles: 0.5ml, 1ml, 2ml, 3ml, 5ml, 10ml.
