Summary: Pure Bi2MoO6 nanosheets and one-dimensional/two-dimensional (1D/2D) multi-walled CNTs/Bi2MoO6 nanocomposites were synthesized via a facile hydrothermal route for room-temperature ammonia monitoring. The 0.5 wt% MWCNTs/Bi2MoO6 nanocomposites showed the best sensing properties, including low detection limit (157 ppb), high response (Ra/Rg = 44.2 @ 50 ppm), selectivity, reproducibility, and anti-humidity sensing ability. The enhanced gas sensing mechanism was proposed based on the synergetic effect of high-energy crystal facets, modified surface characteristics, and p-n heterojunction.

Summary: In this study, a highly sensitive, selective, and stable microwave gas sensor (MGS) composed of an ultra-narrowband microwave filter transducer and an organic-inorganic hybrid sensitive material (multilayered structured polyaniline (PANI)SnO2) was reported for the first time. The MGS showed the capability to selectively detect low concentration of ammonia (NH3) with high sensitivity, fast response speed, and anti-humidity capacity at room temperature. This work not only develops a new class of microwave sensing functional materials, but also demonstrates the concept of tuning relative permittivity for constructing outstanding performance microwave gas sensor.

Summary: First-principles calculations were conducted to investigate the adsorption behavior of ammonia on Ti3C2O2, Ti3C2F2, Ti3C2H2, Ti3C2S2, and Ti3C2Cl2. Different adsorption sites and functional groups were studied. The results showed that the best adsorption positions were all at the alpha site, and the adsorption strength followed the order of Ti3C2H2 > Ti3C2O2 > Ti3C2F2 > Ti3C2S2 > Ti3C2Cl2. It was suggested that Ti3C2 surfaces modified with the -O group were more suitable for ammonia detection.

Summary: The use of green hydrogen for decarbonization has attracted attention, and ammonia can be used as a chemical to transport and distribute green hydrogen while improving the operability of power systems. However, pure ammonia shows slow reaction kinetics and requires doping with more reactive molecules. Ammonia is expected to replace natural gas in power and heat production, and hydrogen can be obtained from the pre-cracking of ammonia. Therefore, the analysis of combustion properties of ammonia/methane/hydrogen blends is important for the transition to renewable energy.

Summary: Alzheimer's disease is a major cause of senile dementia and is characterized by the aggregation of neurofibrillary tangles and amyloid plaques in the brain. The A beta 1-42 peptide is considered the primary cause of neurotoxicity due to its insolubility and subsequent aggregation. A beta 1-42 and A beta 1-40 have been identified as relevant biomarkers for AD diagnosis, and SurfaceAssisted Laser Desorption/Ionization Mass Spectrometry (SALDI-MS) was used to monitor the A beta 1-42/A beta 1-40 ratio without prior sample treatment.
