How do Coulomb barrier tunneling phenomena affect nuclear physics?
Best insight from top research papers
Coulomb barrier tunneling phenomena have significant effects on nuclear physics. One effect is the enhancement of tunneling rates through the inter-nuclear Coulomb barrier, which can be achieved by increasing the effective negative electric charge in the mid region between two protons or deutrons in a molecule placed inside a molecular cage . At high energies, tunneling becomes completely transparent in the asymptote, acquiring characteristics inherent in regular potentials . Another phenomenon is Klein tunneling through the Coulomb barrier, which is observed when beams of medium-energy electrons and positrons scatter from nuclei with high atomic numbers . Additionally, a resonant tunneling model has been proposed to explain anomalous phenomena in nuclear reactions in solids, suggesting that resonant tunneling through the Coulomb barrier may play a role in low-energy nuclear transmutation . Finally, tunneling between parallel two-dimensional electron gases in double quantum wells is influenced by Coulomb correlations, resulting in alterations in the tunneling density of states .

What is the nuclear energy?5 answersNuclear energy is a significant form of energy harnessed from the nuclei of atoms, providing clean, reliable, and cost-effective power while mitigating climate change impacts. It plays a crucial role in the global energy landscape, with over 400 reactors in 32 countries generating about 10-15% of the world's electricity. The history of nuclear energy dates back to the discovery of radioactivity and X-rays, leading to the realization of the immense energy potential within atoms. Nuclear fission energy, a key component of many countries' energy matrices, has advantages but also raises concerns about accidents, emphasizing the importance of understanding nuclear reactions and plant operations. Additionally, advancements in fusion technology, like the ITER project, hold promise for long-term energy security through clean and abundant fusion reactions.
What can be the reason for presence of mitochondria in nuclear pellet?3 answersThe presence of mitochondria in the nuclear pellet could be due to several reasons. One possibility is that the entrance of mitochondria into the nucleus promotes interactions between mitochondrial and nuclear proteins, as well as between mitochondrial proteins and nuclear DNA. Another reason could be the release of mitochondrial supernatants, which contain effective components, including proteins, that can induce apoptotic changes in nuclei. Additionally, the function of nuclear-localized mitochondria is still unknown, but it has been observed that mitochondria can fragment and disperse into particles, which then reassemble to initiate nuclear formation and development. These particles, consisting of dense microvesicles, can also reverse the nuclear formation of the organelles. Therefore, the presence of mitochondria in the nuclear pellet may be a result of various processes involving interactions between mitochondrial and nuclear components, as well as the fragmentation and reassembly of mitochondria during nuclear formation and development.
What is nuclear pasta?5 answersNuclear pasta is an exotic form of nuclear matter that occurs in the crust of neutron stars below saturation density. It consists of various exotic nuclear structures with cylindrical, planar, and more complicated geometries. These structures affect the cooling, rotation, and gravitational wave emission of neutron stars. Quantum calculations show that nuclear pasta becomes a self-organized glassy amorphous solid at characteristic temperatures, similar to soft-matter systems on Earth. The pasta phases in neutron star crusts occupy local minima in the Gibbs energy surfaces and can coexist in a given layer. At a characteristic temperature, different phases become frozen into domains, leading to temperature-dependent transport properties in the crust. Nuclear pasta structures can have different shapes, such as droplet, rod, slab, tube, and bubble, and can evolve into each other via volume conserving deformations. As temperature increases, the long-range ordering in nuclear pasta structures is disrupted, and they eventually convert into uniform nuclear matter.
How does nuclear energy work?5 answersNuclear energy works by harnessing the energy released during reactions involving atomic nuclei. These reactions, such as fission and fusion, convert mass into energy, releasing enormous amounts of energy in the process. In fission reactions, atoms are split, and about 0.1% of the reacting mass is converted into heat. This heat is then used to raise steam and drive a steam turbine, generating electricity. Nuclear reactions can also generate new fissile species, such as the conversion of uranium-238 into plutonium. Nuclear fission releases one million times more energy per atom than any chemical reaction, making it a highly efficient source of energy. Additionally, nuclear energy does not produce many of the pollutants associated with combustion, making it a cleaner option.
How does nuclear energy work?3 answersNuclear energy is a process that involves transforming the energy contained in the atomic nucleus into a useful form, such as electricity. The main reaction used in nuclear energy is fission, where a free neutron induces the splitting of the atomic nucleus, releasing a large amount of energy. This energy release is about one million times higher than that of any chemical reaction. Nuclear reactors are designed and operated to control temperature and pressure levels and minimize risks associated with nuclear energy. Over the past 60 years, efforts have been made to harness nuclear fission due to its high energy efficiency and lack of pollutants compared to combustion processes. Nuclear energy can contribute to sustainable development by increasing energy utilization efficiency and reducing environmental emissions, as demonstrated in a case study for Ontario.
How does nuclear aircraft engine work?5 answersA nuclear aircraft engine works by utilizing a micro engine or a nuclear power engine to generate power for the aircraft. The micro engine consists of an air compressor, a reactor core, a turbine, and a generator. The nuclear power engine includes a compression barrel, a rotary barrel, a spherical burner, and a main shaft, with positive and reverse arc vortex blades for gas intake, compression, burning, acting, gas exhausting, and gas suction. Another type of nuclear energy airplane engine includes an accelerator system and an engine system, with a turbo driven by vaporized and swelled water from nuclear fusion, generating power for the aircraft. Additionally, there is a combined nuclear boost aircraft engine that incorporates a Stirling engine downstream of the turbine, connected to a nuclear reactor via heat carrier lines, and includes operating and expansion cylinders for increased efficiency.
