A test system for gas sensors

, 2022
S.163-172An important instrument for development of gas sensors is the test and measurement system. Whereas for calibration of commercial gas sensors prefabricated gas mixtures were often used, for research purposes a more flexible system is needed.

Time-dependent investigation of a mechanochemical synthesis of bismuth telluride-based materials and their structural and thermoelectric properties

Royal Society Open Science, 2022
Here, we report on the time dependence of a synthesis procedure for generation of both n- and p-type bismuth telluride-based materials. To initiate the reaction, the starting materials were first mechanical pre-reacted.
