Researchers at the National Institute of Standards and Technology, Gaithersburg, Md., developed a laser-based method that uses high-intensity laser to blast microscale projectiles into a small sample at velocities close to the speed of sound to analyze the energy exchange and predict the puncture resistance of materials against larger projectiles encountered in real-world situations.
For the first time, scientists at Sandia National Laboratories, Albuquerque, N.M. and Texas A&M University, have witnessed pieces of metal crack, then fuse back together without any human intervention, overturning fundamental scientific theories in the process.
Researchers at NC State University created a way to print solid metals at room temperature using metallic gels that can be used for 4D printing (3D printed structures that change shape with respect to time in response to an external stimulus).
The Convergence Center for Living Multifunctional Material Systems, a transatlantic research partnership between Penn State and the University of Freiburg in Germany, is focused on this emerging field. Working together and across disciplines, researchers from Penn State and Freiburg are applying living materials to the challenges of adaptive architecture.
For the second time, U.S. researchers have achieved net energy gain in a nuclear fusion reaction. The amazing feat, which uses lasers to fuse two atoms, brings investigators one step closer to discovering a near-limitless, safe, and clean source of energy.
