Summary: Fouling of seawater reverse osmosis (SWRO) membranes can be effectively removed by using Supercritical carbon dioxide (sCO2) fluid as a cleaning reagent. The sCO2 cleaning removes extracellular polymeric substances (EPS) from the membrane surface with a cleaning efficiency of 75-90%. It was found that sCO2 cleaning does not affect the properties of polyamide-based SWRO membranes.

Summary: The fouling of seawater reverse osmosis membranes is a persistent challenge in desalination. This study monitored the operational performance of a desalination plant for 7 years and the fouling development in different areas of membrane modules. The findings showed that operational performance declined over time and fouling mainly occurred at the feed side of the modules, with the highest microbial diversity. Keystone species like Chloroflexi and Planctomycetes played an important role in maintaining community structure and biofilm maturation. Polysaccharides, soluble microbial products, marine humic acid-like substances, and inorganic substances contributed to fouling. Overall, biofouling had a significant impact on membrane fouling after 7 years of operation.

Summary: Increasing population and industrial development have led to a global freshwater shortage crisis. Desalination, particularly membrane-based desalination technology, has proven to be an effective solution. However, the current membranes used in desalination face challenges such as low permeation, low selectivity, wetting, and internal polarization. Therefore, researchers are exploring more advanced membranes, and electrospun nanofibrous membranes (ENMs) show promise due to their versatility and ability to address these membrane challenges. In this review, we discuss the application of ENMs in different membrane desalination processes and propose future directions for the development of advanced membranes.

Summary: The combined fouling by gypsum and iron oxides in the Reverse Osmosis (RO) desalination process was studied. It was found that the combined fouling caused a severe decline in water flux and membrane wetting. The flux decline caused by the combined fouling was 50% higher compared to individual fouling by gypsum or iron oxides. The molecular interactions between iron oxides and gypsum, as well as the properties of the formed crystals, were determined.

Summary: Liver disease is a major cause of global mortality, and identifying biomarkers for diagnosing its progression is crucial for improving outcomes. Targeted mass spectrometry is a powerful tool for verifying biomarker candidates and clinical applications, particularly for glycoproteins translation. However, the limitation of analyzing only one sample per run has become apparent. In this study, a high-throughput intact N-glycopeptides quantification strategy was developed, allowing the validation of 20 samples per run with an average analysis time of 3 minutes per sample. The strategy was applied in a cohort of 461 serum samples and identified a panel of 10 IgG N-glycopeptides that have strong clinical utility in evaluating the severity of liver disease.
