Summary: Hierarchical S-doped In2O3 networks were synthesized with graphene oxide as a template and annealed. The effects of graphene oxide and annealing temperature on the morphology and phase of the samples were investigated. The hierarchical S-doped In2O3 networks consisted of nanosheets and microspheres assembled with nanowires and nanoparticles. The annealed hierarchical S-doped In2O3 networks at 500 degrees C showed the highest response (Ra/Rg) of 74.4 towards 50 ppm ethanol at 180 degrees C, which was approximately 2 times higher than that of S-doped In2O3 micro pompons prepared without graphene oxide. Moreover, the hierarchical In2O3 networks exhibited excellent selectivity and good stability to ethanol, which may be attributed to their unique hierarchical networks, high specific surface area (295.23 m2/g), and sulfur doping.

Summary: This paper presents a room temperature ammonia sensor without heating device. Three-dimensional hierarchical SnS2 nanoflowers were obtained by hydrothermal synthesis and subsequent calcination at 450 degrees C. Gas sensing performance of the sensors was systematically investigated for ammonia at 20 +/- 2 degrees C. S-doped SnO2 showed improved response, selectivity and stability compared to pristine SnS2, possibly due to its enhanced conductivity and the unique 3D hierarchical nanoflower structure. The results suggest that 3D hierarchical S-doped SnO2 nanoflowers are promising for ammonia detection.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
