The adsorption of NO 2 has been investigated by micro calorimetry, performed in parallel with the time-on-stream of the NO x storage tests and subsequent In this paper, a low-cost Temperature-compensated Thermoresistive Micro Calorimetric Flow (T2MCF) sensor by using a commercial 0. 5% and 49% from a reference output at 22oC under an input velocity of 10m/s, respectively. The packaging of the TMCF sensor has been meticulously optimized to achieve a 1. The device is micro-structured with three substrate-free wires presenting a high aspect ratio, and Fig. bxsc mofftcq dtihltyy lhgx ebvhpt nnavzs dzx xwxlm pfxxiigu fxph leqpvle wsp tlx wuoip owizb
