Summary: Fluorescence characteristics of dissolved organic matter (DOM) in the Huangpu River water were studied using fluorescence excitation emission matrix (EEM) coupled with parallel factor (PARAFAC) analysis. Different components of fluorescence were identified with spatial and temporal variations, and the correlation between microbial humic-like fluorescence and the formation potential of N-DBPs was observed, providing insights for controlling specific DBPs precursor. Additionally, humic-like components were found to correlate with the concentrations of triazole and organophosphate pesticides in the Huangpu River, indicating the potential of fluorescence-PARAFAC analysis in assessing DBPFPs and pesticide occurrence in surface waters.

Summary: This study investigated the potential release characteristics of dissolved organic matter (DOM) from hydrochar (HDOM) under various environmental conditions. It was found that alkalinity and high temperature conditions can enhance the leaching amount of HDOM and change its chemical quality. Released HDOM may have significant impacts on ecosystem functionality.

Summary: This study reveals the seasonal and location-dependent dynamics of dissolved organic matter (DOM) in tap water and source water of a metropolitan city. Significant changes in fluorescent DOM (FDOM) composition were observed between wet and dry seasons. Optimizing operational conditions of drinking water treatment plants is crucial after considering seasonal changes and source water characteristics.

Summary: Contaminants in water were studied using ultraviolet absorption with light emitting diode and deuterium lamp sources, and a thresholding detector. The transmitted signal of contaminants and mixtures of pairs of compounds could be approximately described with a simple spectral model of the source-absorption-detector system, allowing for relative concentrations to be determined in certain mixtures. Real-time absorption measurements in a flume were successfully demonstrated.

Summary: This research provides a quick and non-destructive method for estimating the freshness of refrigerated fish using multispectral imaging coupled with multivariate analysis techniques. By measuring fluorescence EEMs and utilizing various lighting devices, along with biochemical analysis and regression modeling, a novel algorithm was proposed as a potential indicator of fish freshness. The results show that the fluorescence multispectral imaging technique has great potential for non-destructive monitoring of fish freshness during storage.

Summary: This study investigates the fluorescence characteristics of bean sprouts and explores its potential for tracking the freshness state of bean sprouts. The results show that fresh bean sprouts exhibit two fluorescence regions, representing amino acids and vitamins, respectively. As the sprouts start browning, a new fluorescence region appears. This basic fluorescence information can be utilized to easily inspect the physical and chemical changes of bean sprouts.

Summary: This study focuses on examining fluorescence proxies to distinguish chromophoric matter in different fungi. Amino acids, melanin-like compounds, NAD(P)H, and flavins were found to contribute to fungal autofluorescence. Protein fluorescence can be used to detect general microbial contamination. The combination of fluorescence spectra and principal component analysis algorithms can improve the detection capability of fungal contamination of aquatic environments.

Summary: The evolution of fluorescent compounds in extra virgin and flavored olive oils during thermal degradation was studied using fluorescence spectroscopy. The Parallel Factor Analysis (PARAFAC) method was employed to analyze the fluorescence data, revealing the presence of five fluorophores in the oils, whose evolution is temperature-dependent. The bioactive compounds in the flavoring process, such as lemon, chili, pepper, and basil, were found to enhance the overall oxidative stability of the olive oil, except for garlic flavoring.

Summary: In this study, a new fluorescence approach based on excitation emission matrix (EEM), combined with a new algorithm called matrix reconstruction coupled with prior linear decomposition (MR-PLD), was developed to simultaneously quantify multiple dissolved organic matter (DOM) components. The method was validated using simulated water samples and showed higher accuracy and convenience compared to other methods. The anti-interference performance of MR-PLD was also tested using both simulated and experimental methods. Real water samples from natural waters and wastewater treatment plants were analyzed to confirm the method's robustness. This study provides a new approach for characterizing DOM and exploring its environmental impacts.

Summary: Membrane distillation, an emerging desalination technology, has great potential for treating high-salinity industrial wastewater. However, the wetting of hydrophobic membranes has posed a major challenge. In this study, an omniphobic membrane was prepared by growing nano-ZnO needles on a PVDF membrane surface, followed by fluorination. The modified membrane exhibited superior antiwetting properties and high salt rejection, making it promising for treating high-salinity wastewaters containing surface-active substances.
