When an MOF takes in gas or liquid molecules, its tiny framework changes ever so slightly: It may change in size, how it bends light, or how it conducts electricity, depending on what and how many ...
Abstract: This paper presents two low-frequency high-directional electrochemical second-order hydrophones based on the velocity gradient pure partial derivative (VGP) and the velocity gradient mixed ...
Abstract: Distributed acoustic and temperature sensing (DATS) uses Rayleigh backscattering and coherent light pulses to monitor dynamic temperature and vibration over several kilometers. This letter ...
