• Drexel Researchers Use Layered Metals to Show How Nature's 'Dislocations' Occur

    September 19, 2016

    Every material can bend and break. Through nearly a century’s worth of research, scientists have had a pretty good understanding of how and why. But, according to new findings from Drexel University materials science and engineering researchers, our understanding of how layered materials succumb to stresses and strains was lacking. The report suggests that, when compressed, layered materials — everything from sedimentary rocks, to beyond-whisker-thin graphite — will form a series of internal buckles, or ripples, as they deform.

  • Containing Our 'Electromagnetic Pollution'

    September 08, 2016

    If you’ve ever heard your engine rev through your radio while listening to an AM station in your car, or had your television make a buzzing sound when your cell phone is near it, then you’ve experienced electromagnetic interference. This phenomenon, caused by radio waves, can originate from anything that creates, carries or uses an electric current, including television and internet cables, and, of course cell phones and computers. A group of researchers at Drexel University and the Korea Institute of Science & Technology is working on cleaning up this electromagnetic pollution by containing the emissions with a thin coating of a nanomaterial called MXene.
