Cyclic Healing Removes Defects In Metals While Maintaining Strength

source: ECN article Tue, 10/20/2015 – 9:36am by Carnegie Mellon University When designing a new material, whether for an airplane, car, bridge, mobile device, or biological implant, engineers strive to make the material strong and defect-free. However, methods conventionally used to control the amount of defects in a material, such as applying heat or mechanical […]

A ‘Hot’ New Development for Ultracold Magnetic Sensors

source: ECN article Magnetoencephalography, or MEG, is a non-invasive technique for investigating human brain activity for surgical planning or research, and has been used in hospitals and universities for more than 30 years. It’s just one of the many powerful technologies made possible by a tiny device called a SQUID, short for superconducting quantum interference […]

General Motors chooses ultracapacitors for start-stop
