Summary: In this study, novel Bi2S3/NiCo2O4 nanocomposites (BS/NCO) were prepared using NiCo-MOF as a precursor. The morphology, composition, and structure of the catalysts were characterized by various techniques. The 20% Bi2S3 (%20 BS/NCO) composite showed the best catalytic performance in the reduction reaction of 4-nitrophenol (4-NP). The improved catalytic activity of the %20 BS/NCO composite can be attributed to the optimized synergistic effects between the two pristine materials. Thermodynamic parameters and the activation energy of the reaction were calculated, and DFT calculations were used to explore the mechanism of 4-NP reduction in the presence of the BS/NCO composite. Furthermore, the BS/NCO composite was applied in the catalytic reduction of organic dyes.

Summary: This article reports a method for preparing cellulose nanofiber (CNF) dry powders that can be redispersed with water while maintaining high transparency, viscosity, and controllable viscosity based on the shear rate. Dehydration and vaporization procedures are discussed to prepare dry powders without the use of additives. Dry powders prepared by boiling exhibit transparency but do not recover their initial viscosity, while freeze-dried powders fully recover all their initial properties but have a larger volume that does not reduce transportation and storage costs. Evaporative dry powders from solvent-exchanged CNF organogels fully recover all their properties and have small volumes and good handling, contributing to the reduction of transportation and storage costs.

Summary: In this study, cellulose nanofiber (CNF) sheets were used to capture and preserve extracellular vesicles (EVs) for analysis of bioactive molecules inside EVs. The results showed that CNF sheets allowed for the detection of cancer-associated miRNAs in the early phase of ovarian cancer, even before the appearance of ascites. Furthermore, EVs from different locations exhibited unique miRNA profiles, and location-based differences in EV miRNA profiles were identified in patient samples, reflecting disease conditions. Spatial exosome analyses using CNF sheets revealed location-dependent heterogeneity of ascites EVs from cancer patients.

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.
