3D excavatorORNL unveils 3-D printed excavating machine

(The Tennessean) When the group of excited engineers first proposed the trailblazing project to the Oak Ridge National Laboratory, they dreamed of construction equipment that could build the first human colony on Mars. The engineers had just toured ORNL's Manufacturing Demonstration Facility and marveled over a car made by a 3-D printer...9/19

Study yields new knowledge about materials for ultrasound and other applications

(PhysOrg) The lighter wand for your gas BBQ, a submarine's sonar device and the ultrasound machine at your doctor's office all rely on piezoelectric materials, which turn mechanical stress into electrical energy, and vice versa...Now, scientists at the Department of Energy's Oak Ridge National Laboratory and their research partners have used neutron scattering to discover the key to piezoelectric excellence in the newer materials, which are called relaxor-based ferroelectrics...9/16

Jet fuel may be grown on iconic Aussie gum trees

(MyScience) ...Scientists are a step closer to using Australia's iconic gum trees to develop low-carbon renewable jet and missile fuel. Dr Carsten Kulheim from The Australian National University (ANU), a lead researcher in an international study published in Trends in Biotechnology , said renewable fuels that could power commercial aeroplanes were limited and expensive but a solution could be growing all around us...ANU conducted the study in collaboration with Oak Ridge National Laboratory, University of Tennessee and University of Florida in the United States...9/19

Unlocking potential of 3D printed rocket parts with neutrons

(Nanowerk) ...Engineers from NASA's Marshall Space Flight Center in Huntsville, Alabama, used neutrons recently to help understand the potential benefit of additive manufactured rocket engine components. The team used the Neutron Residual Stress Mapping Facility at Oak Ridge National Laboratory's (ORNL) High Flux Isotope Reactor (HFIR), beam line HB-2B, to study residual stress in additive manufactured materials...9/17

White House and NASA Defend Asteroid Redirect Mission, Senate Skeptical in New Bill

(AIP) The White House Office of Science and Technology Policy and NASA held an event this week to explain the rationale for the administration’s proposed Asteroid Redirect Mission. Congress has been skeptical about the mission's value, and this skepticism was further confirmed in a new Senate NASA reauthorization bill released yesterday...9/16


Getting the Most out of Solar Panels

( If you're thinking about going solar at your home or business, you want the biggest bang for your buck. Luckily, solar is cheaper than ever, thanks to the falling cost and rising efficiency of photovoltaic (PV) solar panels. But here’s something to consider: figuring out the real cost of solar energy is about more than just the price tag on the panels and their rated power output...9/16
