Wall-free droplet microfluidics for probing biological processes by high-brilliance X-ray scattering techniques

open access: yesFrontiers in Molecular Biosciences, 2022
Here we review probing biological processes initiated by the deposition of droplets on surfaces by micro- and nanobeam X-ray scattering techniques using synchrotron radiation and X-ray free-electron laser sources. We review probing droplet evaporation on

Large current noise in nanoelectromechanical systems close to continuous mechanical instabilities [PDF]

open access: yes, 2012
We investigate the current noise of nanoelectromechanical systems close to a continuous mechanical instability. In the vicinity of the latter, the vibrational frequency of the nanomechanical system vanishes, rendering the system very sensitive to charge ...
