What is Nobelium Used for | Detailed Explanation

Nobelium is an extremely rare substance in the world, and people do not know much about it. If you are curious about it, have many questions in mind, such as what is nobelium used for? Firstly, you should know about the discovery of nobelium.

The discovery of nobelium

In 1957, a team of scientists working at the Nobel Institute in Stockholm first claimed to have discovered nobelium No-254, but their results were incorrect. Subsequently, in 1958, scientists at the University of California in the United States finally synthesized No-254.

When creating nobelium No-254, Berkeley's research team abandoned the cyclotron that had been used to successfully prepare a series of transuranic elements and replaced it with a heavy ion linear accelerator, successfully preparing No-254 by bombarding a mixture of curium-244 and curium-246 samples with carbon-12 ions. Later, a research group of Russian physicists confirmed this.

In 1971, nobelium No-259 was synthesized at the Oak Ridge National Laboratory in the United States. There are 11 isotopes of No-2 that have been prepared so far, and all of them are radioactive. Among them, nobelium No-261 has the longest lifespan, with a half-life of 170 minutes; Next is nobelium No-259, with a half-life of 58 minutes; The shortest half-life is nobelium No-254, which is only about 1 minute. We can see that the existence of the nobelium is just an instant like the Epiphyllum.

The uses of nobelium

What is nobelium used for? In fact, due to the limitations of the technological level, the use of nano elements in real life is not much at present. But based on its nature, it may be used in the following fields in the future:

1.High-temperature superconducting material: Nobelium’s melting and boiling points are both very high, it can be used as a superconducting material in high-temperature environments. By using nano elements in high-temperature superconducting materials, the critical temperature of superconductors can be raised, thereby improving their performance.

2.Aerospace materials: Nanometer elements have a very high density, so they can be used as high-density materials in the aerospace field. For example, the element can be used to manufacture structural components and components of aircraft and spacecraft to improve their strength and weight ratio.

3. Nuclear energy application: The atomic nucleus of the element No-2 is very unstable and has a short half-life, so it can be used to manufacture fuel for nuclear reactors. For example, No-259 can be used as fuel to produce energy.

Measurement of the nobelium’s mass

In addition to the 92 naturally occurring elements on Earth, scientists have successively discovered more than 20 man-made chemical elements. Among these elements, elements with atomic numbers exceeding 103 (or 105) are referred to as overweight elements.

So far, the lifespan of the generated overweight elements has been very short, mostly in the order of seconds and milliseconds. Due to the small number and short lifespan of overweight atomic nuclei, scientists have been unable to directly measure their mass and charge, and can only measure their α The decay chain is used to infer indirectly.

Now, the international scientific research team in Germany has successfully developed a complex experimental device and connected it to a velocity filter that had previously discovered six overweight elements. Not only did it successfully capture the nano atom, but it also accurately measured its mass.

Scientists first use calcium ions emitted by accelerators to bombard lead foil to produce nanoparticles, and then use filters to separate nanoparticles from other reaction products. In the device, nano ions are first slowed down in a gas-filled cavity and then captured by the so-called Penning ion trap.

Under the action of an ion trap magnetic field, the mass of a nano ion can be directly calculated by moving at a specific frequency on a very small spiral orbit. The accuracy of measurement can reach 5 parts per million. This is the first time that the mass of a nano atom has been directly determined with unprecedented accuracy without the help of theoretical assumptions.
