5 hours ago · The team’s research could lead to improved, easier ways of separating the lanthanides, which have uses ranging from medical to nuclear batteries for space travel. “The biggest hurdle in using promethium is purifying it from the other f-elements,” White said, calling the research “beyond exciting.”
5 hours ago · The Boltzmann distribution describes the likelihood of a particular state of a system being observed when the system is in thermal equilibrium at a given temperature (T). The mathematical expression for this probability is given by the equation: where: P (E) – is the probability of the state with energy (E). k – is the Boltzmann constant.
5 hours ago · The most common nuclear reaction in stars is the fusion of hydrogen atoms into helium, a process that occurs in the core of the star. This reaction requires high temperatures and pressures, and it is only possible because of the immense gravitational forces that hold the star together.
5 hours ago · Brown dwarfs are substellar objects that have more mass than the biggest gas giant planets, but less than the least massive main-sequence stars.Their mass is approximately 13 to 80 times that of Jupiter (M J) —not big enough to sustain nuclear fusion of ordinary hydrogen (1 H) into helium in their cores, but massive enough to emit some light and heat from the fusion of deuterium (2 H).
5 hours ago · In 2015, he was awarded, by the American Nuclear Society, the Edward Teller Medal, which represents the most important recognition in the field of laser fusion physics and high energy density physics in the world. In 2021, he was awarded the Future Science Prize in physical science, which is one of the most prestigious prizes in China.
5 hours ago · IN 2020, JOE BIDEN ran for president on the most ambitious climate action platform in U.S. history. Notably, he committed to reaching net-zero emissions by 2050. The plan calls for the spending of US$400 billion (AU$600 billion) on increased clean energy research and the construction of 500,000 new electric car charging stations by 2030.
5 hours ago · When it comes to energy and the environment, the report highlights novel hydrogen storage and production technologies as having significant potential impact, while nuclear fusion also gets a mention. Forcing together atomic nuclei offers a way of producing potentially limitless amounts of energy but faces huge practical problems such as the ...
