Summary: Sample pretreatment is a crucial step in analyzing and detecting trace targets, and aerogels have shown great potential as extraction materials in sample preparation. This review provides a comprehensive overview of the classification, development, and application of aerogels in solid-phase extraction and solid-phase microextraction from 2010 to 2021. Different types of aerogels, including silica, carbon, organic, organic-inorganic hybridized, and metal-oxide aerogels, have been introduced in these techniques. They have demonstrated excellent adsorption performance and the ability to capture various analytes in environmental, biological, and food samples. The challenges and future prospects for the use of aerogels in sample preparation are also discussed.

Summary: Novel graphite phase carbon nitride/porous carbon (g-C3N4@PC) composites with high specific surface areas, porous structures, and abundant chemical groups were prepared by decorating cellulose nanocrystals (CNCs). These composites were used as coating materials for solid-phase microextraction (SPME) of organochlorine pesticides (OCPs) in water and juice samples. The g-C3N4@PC-coated fibers exhibited better extraction efficiencies and analytical performance for determining low concentrations of OCPs compared to commercial fibers, showing broad prospects for analyzing organic pollutants from environmental samples.

Summary: High pressure processing (HPP) is an effective alternative to thermal pasteurization (TP) for extending the shelf-life and maintaining the sensory quality of fruit juices. This study investigated the effects of HPP on sensory quality and consumer perception of orange and apple juice, and found that treatment and storage conditions significantly impacted sensory quality and consumer liking. Shorter storage times and cold storage were favored by consumers, while HPP showed better sensory preservation compared to TP.

Summary: Systematic investigation on the adsorption performance of polystyrene-based nanospheres towards persistent organic pollutants (POPs) is crucial for high-capacity adsorbent design and toxicological risk assessment. In this study, a series of polystyrene-based nanospheres with controllable microstructures were successfully constructed as model adsorbents. It was found that F-functionalized nanospheres (xFFNs) demonstrated better enrichment effects towards PCBs due to stronger sigma (σ)-hole interactions. The xFFNs-coated SPME fiber showed excellent enrichment performance for PCBs, with detection limits of 0.08-0.89 ng L-1 for trace PCB quantification in treated sewage samples.

Summary: A liquid-liquid microextraction method assisted by switchable deep eutectic solvents (DESs) was used to extract abamectin and endosulfan. Three different DESs were synthesized and their phase transition behavior was evaluated by changing the pH of the solution. The best DES, a mixture of l-menthol and (1S)-(+)-camphor-10-sulfonic acid (5:1), achieved the highest extraction yield and was used for the extraction of abamectin and endosulfan. By optimizing key variables, the method showed good analytical performance with linear concentration range and low detection limits for both analytes. The extraction efficiency of the best DES was examined for water and fruit juice samples under optimal conditions.

Summary: This study investigates the impact of nanoscale geometry and molecular crowding on Aβ fibril sensing using nanopore technology. It was found that a conical nanopore functionalized with PEG 5 kDa can discriminate fibril size, while a bullet-like-shaped nanopore enhances current amplitude and dwell time. However, a nanopore crowded with PEG 20 kDa increases relative current blockade without improving fibril discrimination compared to the bullet-shaped nanopore.

Summary: This study investigates the characteristics and performance of bio-based ceramic membranes made from kaolinite clays, coconut husks, and eggshells for the removal of E. coli bacteria in drinking water. The membranes were characterized using TGA, DSC, mercury porosimetry, and SEM. Water flux density, bacterial removal, and biofouling were evaluated. The results show that the best membrane, S3, achieved 100% bacterial removal with a water flux density of 2123 +/- 72 L/h/m(2) at an initial pressure of 0.2 bar. The production protocol for this membrane is simple, fast, and does not require chemical additives.

Summary: This study investigates the variations in lipid digestion profiles among individuals of different ages using in vitro digestion models. The findings suggest that adults have a more comprehensive lipid digestion compared to infants, and infants tend to release shorter chain length and more saturated free fatty acids during digestion. Additionally, the particle sizes in the stomach of the elderly were consistently larger. This study enhances our understanding of how lipids with different degrees of unsaturation undergo digestion in diverse age groups.

Summary: This study investigated the acidification of aroma-enhanced black tea during storage. Analysis of non-volatile substances and organic acids using UPLC-Q-TOF/MS and HPLC revealed a decrease in soluble sugars and amino acids, while an increase in organic acids such as oxalic acid, malic acid, and quinic acid. In vitro experiments further demonstrated that the acidification is a result of the decomposition of sugars and amino acids by heating, as well as the oxidation of aromatic aldehydes. Additionally, the study showed that the taste composition of tea infusion is altered, with reduced amino acids, catechins, soluble sugars, and flavonoids. This research provides a theoretical basis for improving the quality of black tea.
