Mon 30 Jan 2017. Researchers have, for the first time, measured the lifetime of an excited state in the nucleus of an unstable element. This is a major step toward a nuclear clock that could keep even better time than today's best atomic timekeepers. Atomic clocks, the most precise chronometers we now have, are based on precise knowledge of the frequency of specific transitions between defined energy levels in the electron shells of certain atoms. Theoretical studies suggest that nuclear clocks that make use of analogous changes in the energy states of atomic nuclei could provide even more accurate frequency standards for timekeeping purposes. Research focused on the first experimental detection of a specific energy transition in the nucleus of a particular unstable isotope of the element thorium (Th-229), the only nucleus known to have the properties required for the development of a practical nuclear clock.

Thu 22 Dec 2016. New technique for measuring radiation damage on the fly, thus continuously assess aging of materials in a high-radiation environment, such as nuclear reactor vessel, in real-time. The analytical method potentially allowing for continuous monitoring of these materials without the need to remove them from their radiation environment. This could greatly speed up the testing process and reduce the preventive replacement of materials that are in fact safe and usable. More

Sun 4 Dec 2016. The International Union of Pure and Applied Chemistry (IUPAC) has approved the name and symbols for four newly discovered elements: nihonium (Nh), moscovium (Mc), tennessine (Ts), and oganesson (Og), respectively for element 113, 115, 117, and 118. The exploration of new elements continues, and scientists are searching for elements beyond the seventh row of the periodic table. More

Sun 13 Nov 2017. An international team of scientists suggests that the world must ramp up energy production by nuclear power if we are to succeed in warding off the worst effects of greenhouse gas emissions on climate change. The team suggests that beginning in 2020 we could achieve an annual electricity output of 20 TW without needing to develop carbon dioxide trapping and storage technology for the tens of billions of tons of emissions that would otherwise drive global warming to catastrophic levels. Recent research suggests that it should be physically and economically plausible to multiply by a factor of fifty the production of nuclear energy by 2100, leading to a complete elimination of fossil fuels wherein 60% of electricity demand is met through nuclear and the remainder through sustainable technology.
