Improving mechanical sensor performance through larger damping

15-Jun-2018 | Swapan K. Roy; Vincent T. K. Sauer; Jocelyn N. Westwood-Bachman; Anandram Venkatasubramanian; Wayne K. Hiebert, Science , 2018

Mechanical resonances are used in a wide variety of devices, from smartphone accelerometers to computer clocks and from wireless filters to atomic force microscopes. Frequency stability, a critical performance metric, is generally assumed to be tantamount to resonance quality factor (the inverse ...

Inner Workings: Microscopy lights up stem cells in action [Cell Biology]

12-Jun-2018 | Carolyn Beans, Proceedings of the National Academy of Sciences current issue, 2018

As developmental and cell biologist Valentina Greco stood on a stage in Philadelphia last December, candid time-lapse shots of some of the body’s most elusive cells flashed behind her in quick succession. These stem cells, photographed in a living mouse , were caught in the acts of dividing, ...

Core Concept: “Twisted” light beams promise an optical revolution [Medical Sciences]

29-May-2018 | Adam Mann, Proceedings of the National Academy of Sciences current issue, 2018

Some of history’s most brilliant researchers have studied the nature of light over the centuries, from Newton to Maxwell to Einstein. And yet it continues to surprise. Indeed, one discovery about light’s peculiar behavior offers new insights into how light works while suggesting some intriguing ...

Imaging the chemical activity of single nanoparticles with optical microscopy

29-May-2018 | Wei Wang, Chemical Society Reviews, 2018

Nanomaterials exhibit structural and functional heterogeneity among individual nanoparticles, thus requiring a capability to study single nanoparticles. While electron microscopes often provide static images of their chemical composition, morphology and structure, imaging the chemical activity of ...

Fluorescence in sub-10 nm channels with an optical enhancement layer

24-May-2018 | Junjie Zhong; Soheil Talebi; Yi Xu; Yuanjie Pang; Farshid Mostowfi; David Sinton, Lab on a Chip, 2018

Fluorescence microscopy uniquely enables physical and biological research in micro- and nanofluidic systems. However, in channels with depths below 10 nm, the limited number of fluorophores results in fluorescence intensity below the detection limit of optical microscopes. To overcome this ...
