Detecting and distinguishing between hazardous gases with similar odors by using conventional sensor technology for safeguarding human health ensuring food safety are significant challenges. Bulky, costly, power-hungry devices, such as that used gas chromatography-mass spectrometry (GC-MS), widely employed sensing. Using a single chemiresistive semiconductor or electric nose (e-nose) to achieve this objective is difficult, mainly because of its selectivity issue. Thus, there need develop new materials tunable versatile sensing characteristics. Phase engineering two-dimensional better utilize their physiochemical properties has attracted considerable attention. Here, we show MoSe

The modern view of industrial heterogeneous catalysis is evolving from the traditional static paradigm where catalyst merely provides active sites, to that a functional material in which dynamics plays crucial role. Using machine learning-driven molecular simulations, we confirm this picture for ammonia synthesis catalysed by BaH2. Recent experiments show system acts as highly efficient catalyst, but only when exposed first N2 and then H2 chemical looping process. Our simulations reveal N2, BaH2 undergoes profound change, transforming into superionic mixed compound, BaH2−2x(NH)x, characterized high mobility both hydrides imides.
