Effects of low frequency noise on sleep

open access: yes, 2004
Low frequency noise (20-200 Hz) is emitted by numerous sources in the society. As low frequencies propagate with little attenuation through walls and windows, many people may be exposed to low frequency noise in their dwellings.

Fast Fabrication Nanopores on a PMMA Membrane by a Local High Electric Field Controlled Breakdown

open access: yesSensors
The sensitivity and accuracy of nanopore sensors are severely hindered by the high noise associated with solid-state nanopores. To mitigate this issue, the deposition of organic polymer materials onto silicon nitride (SiNx) membranes has been effective ...
