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.

Wed 9 Nov 2016. Scientists propose technique to immobilize radioactive waste for millions of years by keeping it in glass. Researchers have searched ways to immobilize waste, particularly iodine-129, which has a half-life of 15.7 million years and can disperse rapidly in air and water, making it crucial for its safe storage and disposal in underground geological formations. The research may eventually lead to ways to safely dispose highly radioactive spent nuclear fuel, which is currently being stored at commercial nuclear power plants. More

Wed 5 Oct 2016. The Nobel Prize in Chemistry 2016 was awarded jointly to Jean-Pierre Sauvage, University of Strasbourg, France, Sir J. Fraser Stoddart, Northwestern University, USA and Bernard L. Feringa, University of Groningen, the Netherlands, "for the design and synthesis of molecular machines" More

Mon 19 Sep 2016. New cyclotron used for fundamental and applied research in radiopharmaceutical chemistry. A new particle accelerator is further enhancing the research landscape. It will be used to generate isotopes with a short half-life, which are important for fundamental research but are also required for the medical imaging technique known as positron emission tomography (PET). As it is able to accelerate protons to an energy of 9.6 MeV, the cyclotron can be used to generate the two radioactive elements F-18 and C-11. These will be mainly employed for chemical and pharmaceutical research purposes but are also required for the PET medical diagnostic imaging technique. F-18 and C-11 have short half-lives of just 2 h and 20 min, respectively, which makes it necessary to generate them near the location at which they are to be used to ensure that they are available in sufficient quantities.

Thu 15 Sep 2016. Peculiar metals; Insulator or conductor. The electronic energy states allowed by quantum mechanics determine whether a solid is an insulator or whether it conducts electric current as a metal. Researchers have now theoretically predicted a novel material whose energy states exhibit a hitherto unknown peculiarity. This little known and, so far, not particularly useful solid could be the prototype for a new kind of material with potentially technologically interesting properties. For instance, it is predicted that the electric conductivity of such solids should be influenced by magnetic fields in a characteristic way. This phenomenon is also known as magneto-resistance and plays an important role in modern data storage technologies. More

Thu 28 July 2016. New tool calculates emissions impacts and energy benefits from smart grid investments. Power Smart grid technologies significantly reduce greenhouse gases and other emissions resulting from power production and usage. Taken together, smart grid and intelligent buildings mechanisms could reduce US carbon emissions by 12 percent by 2030. The free web-based tool (EQT, Emissions Quantification Tool) enables power utilities and industry to evaluate not only the environmental impacts of adopting smart grid technologies, but can give organizations the operational data to sift through factors to justify the investment. EQT calculates the resulting changes to carbon dioxide, sulfur dioxide and nitrogen oxides, and the energy and financial savings that may be achieved by integrating smart grid technologies. The evaluated technologies include coordinated electric vehicle charging schedules, battery-stored energy, and devices that enable integration of solar generation into the power grid. More
