If you were looking to nominate a particular technology as the most influential of the early 21st century, batteries would be a logical choice. Cheap, compact batteries made smartphones and mobile computing possible, and larger and more powerful batteries represent the enabling technology behind electric mobility, renewable energy, and the smart grid
Clouds the Likely Cause of Increased Global Warming in Latest Generation of Climate Models – SciTechDaily
New representations of clouds are making models more sensitive to carbon dioxide. As scientists work to determine why some of the latest climate models suggest the future could be warmer than previously thought, a new study indicates the reason is…
(DOE/Oak Ridge National Laboratory) A team led by the Department of Energy’s Oak Ridge National Laboratory used a simple process to implant atoms precisely into the top layers of ultra-thin crystals, yielding two-sided structures with different chemical compositions. The resulting materials, known as Janus structures after the two-faced Roman god, may prove useful in developing energy and information technologies.
Whenever you read a media story about how we’re heading toward a catastrophe if we continue operating “business as usual” — i.e., if we don’t slash carbon emissions — the reports are almost always referring to a model simulation using…
(DOE/Princeton Plasma Physics Laboratory) One way that scientists seek to bring to Earth the fusion process that powers the stars is trapping plasma within a twisting magnetic coil device shaped like a breakfast cruller. But the device, called a stellarator, must be precisely engineered to prevent heat from escaping the plasma core where it stokes the fusion reactions. Now, PPPL researchers have demonstrated that an advanced computer code could help design stellarators that confine the essential heat more effectively.
The continuous development and improvement of numerical models for the investigation of the climate system is very expensive and complex. At GEOMAR a new modular system has now been presented, which allows investigations to be carried in a flexible way, with varying levels of complexity. The system, called FOCI (Flexible Ocean and Climate Infrastructure), consists of different components that can be adapted and used, depending on the research question and available computing power.
(UiT The Arctic University of Norway) Today, large resources are used to provide vessels in the polar seas with warnings about the spread of sea ice. Artificial intelligence may make these warnings cheaper, faster, and available for everyone.
Geoscientists recently used massive amounts of earthquake data and supercomputers to generate high-resolution, 3D images of the dynamic geological processes taking place far below the Earth’s surface. The research team described how it created images of mantle flows in a subduction region under Central America and the Caribbean Sea.
(DOE/Oak Ridge National Laboratory) Oak Ridge National Laboratory welcomed six technology innovators to join the fourth cohort of Innovation Crossroads, the Southeast’s only entrepreneurial research and development program based at a US Department of Energy national laboratory.
