Summary: The study aimed to investigate the influence of PSAS branches on the sizing properties of corn starch, leading to the development of a new starch-based size. Results showed that S-g-PSAS exhibited improved adhesion, viscosity stability, desizability, and film properties compared to HS, with enhancements in bonding forces, viscosity stability, and film properties at higher grafting ratios. This suggests potential for S-g-PSAS as a sizing agent for cotton and viscose fibers.

Summary: In order to improve the oil-water separation efficiency and promote the reinjection of ASP-produced water, a novel cationic graft copolymer CDC was synthesized by ultrasonically assisted copolymerization. The flocculation effect of copolymer CDC on ASP-produced water was investigated, showing better oil removal rate and light transmittance for Nan 4-8-produced water compared to Sanyuan-6-produced water. The addition of CDC promoted the coalescence and separation of large-diameter oil droplets in produced water.

Summary: The impact of microwave treatment on the physicochemical properties of corn kernels was investigated in this study. Corn kernels were treated with three different microwave powers (2, 3, 4 W/g) and three treatment times (2, 3, 4 min). The findings showed that heat treatment increased gelatinization temperature and gelatinization enthalpy of corn kernels, while reducing relative crystallinity. Microwave treatment also led to alterations in protein secondary structure, ordered structure, and functional properties of corn flour. Rheological tests demonstrated that microwave-treated corn gels had higher elastic and viscous moduli compared to the control group, and exhibited a strain-weak strain overshoot (type III) in their large-amplitude oscillatory shear curves. The results suggest that microwave treatment has the potential to regulate the technical functional properties and viscoelasticity of corn flour.

Summary: The study investigates the treatment of negatively charged colloidal materials in water using a nanocomposite of poly diallyl dimethyl ammonium chloride with nano-graphene oxide (NGO/PDADMAC). By exposing the nanographene oxide to 2-bromopropionyl bromide (NGO/BPB), the possibility of interaction with three functional groups (carboxy, hydroxy, and epoxy) is explored. The structural parameters suggest that the complex formed at the carboxy and hydroxy positions has better properties than the epoxy group.

Summary: A cationic starch slurry modified with etherification was developed to solve the insolubility of starch under medium and low temperature. Raw starch was hydrolyzed by sodium hydroxide to improve dispersion performance, and then endowed with cationic groups to improve dispersion stability. Characterization methods showed that the obtained quaternary ammonium cationic starch was soluble in water at medium and low temperature, with changes in starch structure. Furthermore, treating cotton yarn with cationic starch significantly improved mechanical properties and abrasion resistance.

Summary: This study investigated the effect of P(AA-co-BA) branches on the sizing properties of bromoisobutyryl esterified starch (BBES) and developed a new biobased sizing agent. The results showed that BBES-g-P(AA-co-BA) had improved paste stability, bonding forces, film properties, and water solubility compared to acid-hydrolyzed starch (AHS) and BBES. The incorporation of P(AA-co-BA) branches further enhanced the sizing qualities of polyester and polyester/cotton blended yarns.

Summary: UV-B irradiation was found to be a milder modification method than chemical oxidation on corn and potato carbohydrates. Potato carbohydrates, especially amylose, were more susceptible to changes upon irradiation, whereas corn ones, particularly amylopectin, were more stable. Functional properties were not significantly influenced by UV-B treatment.

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.
