ORNL unveils 3D-printed Shelby Cobra in Detroit

It stands to reason that if you had a big enough 3D printer, one of the first things you would do is print a replica of a vintage 1965 Shelby Cobra sportscar, and that's what the Oak Ridge National Laboratory (ORNL) did for the 2015 North American International Auto Show (NAIAS) in Detroit. The result of a project that took only six weeks from conception to finished product, the vehicle not only celebrates the Shelby Cobra's 50th anniversary, but also acts as a demonstration of modern additive manufacturing and rapid prototyping technology.

Water droplet networks could harvest water from fog

Harvesting water out of thin air, might seem like a pipe dream, but the air-stable water droplet networks, currently being developed by Oak Ridge National Laboratory (ORNL) researchers could prove to be a step in the right direction. Created with the aid of a new technique, these water droplet networks could also potentially find use in membrane research and biological sensing applications. Read More

Dual-functioning electrolyte improves capacity of long-life batteries

The three main components of a battery's makeup: the anode, cathode and the ion-conducting electrolyte, have been long understood to serve separate, independent functions. A team of researchers at the US Department of Energy's Oak Ridge National Laboratory (ORNL) is seeking to challenge this theory, experimenting with a dual functioning electrolyte that supplements the cathode to significantly improve the capacity and longevity of long-life batteries.

Gold nanoparticle could allow powerful alpha particles to join cancer fight

Gold nanoparticles have already shown promise in precisely highlighting brain tumors, “blowing up” individual diseased cells, and developing a lung cancer breath test. Now researchers have created gold nanoparticles that allow an alpha particle-emitting element to be directed to small cancer tumors. The researchers say the gold coating keeps the powerful radioactive particles in place at the cancer site so they do negligible damage to healthy organs and tissue. Read More

ORNL roof-and-attic system keeps houses cool in summer, warm in winter

Heating and cooling a house are two of the biggest ongoing costs for homeowners and are responsible for the bulk of the average household’s energy consumption. A new kind of roof-and-attic system field tested at the DoE’s Oak Ridge National Laboratory (ORNL) improves the efficiency of both winter heating and summer cooling. Importantly, the new system can be retrofitted to most existing roofs. Read More

Oak Ridge develops improved way of extracting uranium from seawater

The world’s estimated reserves of uranium are only 6 million tons and with the growing demand for reliable energy free of greenhouse emissions leading to more and more nuclear plants being built, that supply may not last very long. Some estimates place the time before all the uranium is gone at between 50 and 200 years. However, the oceans of the world contain 4.5 billion tons of uranium dissolved in seawater. That’s enough to last something on the order of 6,500 years. The tricky bit is getting it out, but a team at Oak Ridge National Laboratory, Tennessee has come a step closer to economically extracting uranium from seawater with a new material that is much more efficient than previous methods.
