NanoclastSemiconductorsMaterials Mass Spectrometry Gets a New Power Source and a New Life On an insulating polymide tape, the deposited patterned crystal violet spots Mass spectrometry is a chemical analysis and detection tool that has been around for 130 years. In that time there have been so many tweaks and improvements that observers have become a bit blasé about the next big leap in its development. But the latest improvement out of the Georgia Institute of Technology may be the biggest yet for the venerable old analytical tool. In research described in Nature Nanotechnology, the Georgia Tech researchers have managed to make mass spectrometry more sensitive than ever before, more portable, cheaper, and even safer. All of these advancements were accomplished by replacing the direct current power source typically used as a power source with triboelectric nanogenerators (TENGs).

Researchers at Northwestern University—led by Mark Hersam, a Northwestern professor at the forefront of investigating the potential of a variety of 2D materials—have taken a significant step beyond merely characterizing borophene and have started to move towards making nanoelectronic devices from it. In research described in the journal Science Advances, Hersam’s team has for the first time combined borophene with another material to create a heterostructure, which is a fundamental building block for electronic devices. Since this work represents the first demonstration of a borophene-based heterostructure, the researchers believe that it will guide future and ongoing research into using borophene for nanoelectronic applications.
