The researchers also imaged softer microtubules to show the efficacy of thermal noise imaging on softer structures. (nanotechweb.org)
Spence expects that by cooling the tip with liquid nitrogen, they should be able to reduce thermal noise enough to make the more mobile ones stick. (sciencemag.org)
c) You are measuring in the IR, so as you go to lower wave number (longer wave length) there is more thermal noise from the detector and spacecraft itself. (realclimate.org)
