Summary: Understanding the nanostructures of liquid electrolytes is crucial for enhancing electrochemical energy storage capacities, but the solvation structures and molecular dynamics in electrolytes are difficult to probe. Small-angle X-ray scattering (SAXS) offers unique insights into molecular clusters and ion pairs in electrolytes, with excellent time-resolution for studying molecular dynamics. This review focuses on the microscopic understanding of liquid electrolytes by SAXS and highlights the unique capabilities of X-ray scattering for nanostructure characterization.

Summary: This study developed novel gel beads with bigel structures based on alginate hydrogel and glycerol monostearate oleogel. The beads were able to encapsulate lipophilic and hydrophilic bioactives simultaneously. The increase in oleogel content led to larger bead size, higher oil filling level, and lower mechanical strength. The swelling of beads was inhibited by the increase in oleogel content. The gel structures provided good protection for curcumin, and about 70% of the original curcumin was retained after a 40-day storage test. The study provided valuable information for the development of functional food materials.

Summary: The aim of this study was to develop a microencapsulate of a complex matrix using polysaccharides to protect and control the release of CPC. The results showed that the encapsulation efficiency of the matrix-type encapsulates increased as more components were added to the mixtures. Therefore, matrix M4 exhibited an encapsulation efficiency for CPC of 98% and a bioaccessibility of 10.65 +/- 0.65% after the passage of encapsulates through in vitro digestion.

Summary: This study reveals the reversible modulation of protein-protein and protein-chromophore interactions of Cphycocyanin (C-PC) from Spirulina platensis under hydrostatic pressure. The results show that high pressures can disassemble C-PC into monomers or detached subunits, accompanied by protein unfolding. The pressure-induced changes in structure and color can be precisely manipulated and reversed. This knowledge can be used to design new delivery and optical materials.

Summary: The addition of E. faecium CECT 410, either as free cells or in alginate beads, was effective in producing probiotic dry-fermented sausages, with acceptable weight losses and lower pH values during ripening and storage. The sausages with probiotics via alginate beads had higher protein and fat content, but lower moisture content, without affecting lipid oxidation. Counts of E. faecium CECT 410 remained high throughout the ripening and storage periods, making it an effective method for probiotic sausage production.

Summary: In this study, a biocomposite made of alginate and gelatin crosslinked with genipin was developed for immobilizing beta-galactosidase. The microstructure, thermal stability, and operational stability of the immobilized enzyme were analyzed using thermal analyses and SAXS. The results showed that the addition of genipin and enzyme significantly reduced the size and density of the Ca(II)-alginate rods in the biocomposite. The immobilized beta-galactosidase exhibited high storage stability and retained a high relative activity after multiple reuses in lactose hydrolysis.

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.
