Spatial tracking of individual fluid dispersed particles via Raman spectroscopy.
Benjamin Thomas Hogan, Jennifer O'Dowd, Joaquin Faneca Ruedas, Alexander Baranov, Anna Baldycheva
Sep 01, 2021
We demonstrate a method for the spatial tracking of individual particles, dispersed in a fluid host, via Raman spectroscopy. The effect of moving a particle upon the intensity of different bands within its Raman spectrum is...
Dynamic modulation of modal coupling in microelectromechanical gyroscopic ring resonators

Abstract: Understanding and controlling modal coupling in micro/nanomechanical devices is integral to the design of high-accuracy timing references and inertial sensors. However, insight into specific physical mechanisms...
Polar surface structure of oxide nanocrystals revealed with solid-state NMR spectroscopy
Junchao Chen, Xin-Ping Wu, Michael A. Hope, Kun Qian, David M. Halat, Tao Liu, Yuhong Li, Li Shen, Xiaokang Ke, Yujie Wen, Jia-Huan Du, Pieter C. M. M. Magusin, Subhradip Paul, Weiping Ding, Xue-Qing Gong, Clare P. Grey, Luming Peng
