In this paper, we report the discrimination of the viability of human umbilical cord mesenchymal stem cells (hUC-MSCs) with photo-induced delayed luminescence (DL). We measure the DL decay kinetics of hUC-MSCs using an ultraweak luminescence detection sys
Herein, high-quality n-ZnO film layer on c-sapphire and well-crystallized tetragonal p-BiOCl nanoflakes on Cu foil are prepared, respectively. According to the absorption spectra, the bandgaps of n-ZnO and p-BiOCl are confirmed as ~3.3 and ~3.5 eV,
Railway turnout contact monitoring is very important in high-speed rail operation systems. In order to measure the distance between the sharp rail and the basic rail in a switch system, a wide-range, high-precision fiber Bragg grating (FBG) displacement s
