5+ day, 22+ hour ago   (731+ words) Detecting radiation is key to technologies ranging from particle accelerators and scientific instruments to medical imaging and security screening. But current detectors must often make tradeoffs, providing signals that are strong but slow or fast but weak. The tradeoff between…...

1+ week, 3+ day ago   (865+ words) “No flying machine will ever fly from New York to Paris,” aviation pioneer Orville Wright once said. What even the visionary Wright brothers considered impossible is now a reality – thanks in part to new materials that make modern aircraft and…...

3+ week, 3+ day ago   (280+ words) By redesigning the plasticizer as part of the end-of-life chemistry, researchers created a polymer system that links flexibility during use with an entirely different role after disposal. Paper: Plastics to fertilizer: A polymer system based on isosorbide as a monomer,…...

4+ week, 1+ day ago   (460+ words) Commercial nanoindentation was conceived and developed in Oak Ridge, Tennessee, precisely for its unique ability to characterize the mechanical strength of ion-irradiated surfaces. By continuously measuring load and penetration throughout the entire indentation cycle, Young’s modulus and an equivalent Vickers…...
