Article Abstract
Hairtail (Trichiurus haumela) is prone to spoilage due to lipid oxidation and microbial activity during cold storage, necessitating the development of new preservatives to maintain their quality. In this study, grapefruit essential oil microcapsules (GEOs) were prepared by ionic crosslinking of chitosan and sodium tripolyphosphate. The optimal GEOs preparation parameters were established through sequential single-factor experiments followed by response surface methodology. Researchers systematically characterized GEOs and assessed their efficacy in prolonging the shelf life of refrigerated hairtail. Results indicated that GEOs exhibited an irregular spherical morphology with a porous, rough surface. Encapsulation improved thermal stability and conferred potent antioxidant and antibacterial activity. The storage stability of GEOs at 4 °C was superior to that at 25 °C, and the release amount did not exceed 50 % after 300 mins of exposure to anhydrous ethanol. Experimental results demonstrated that GEOs effectively prolonged hairtail shelf-life, validating their potential as an effective seafood preservative.

Herein, we present a simple and novel method to prepare soybean protein isolate (SPI)-based hydrogels with good mechanical characteristics. First, SPI/DSA hydrogels were prepared using SPI and different M/G ratios (1:2, 1:1, and 2:1) of dialdehyde sodium alginate (DSA). Then, the hydrogels were immersed in CaCl2 solution to form SPI/DSA@Ca double network hydrogels.

Dynamic micro/nano-structured surfaces play pivotal roles in biological systems and engineering applications. Despite considerable progress has been made in fabricating precisely ordered architectures, achieving controlled motion in top-down fabricated structures remain a formidable challenge. Here, we introduce an advanced dynamic micron-nano optical platform featuring hierarchical microscale wrinkles integrated with ordered nanoscale arrays.

In order to develop an alternate material for energy storage devices like batteries, this research is being done to create polymer electrolytes based on cellulose as natural polymer. Natural polymers as battery components have a number of advantages, including availability, biodegradability, unleakage, stable form, superior process, electrochemical stability, and low cost. In this study, polymer electrolytes based on cellulose have been synthesized by solution casting to prepare a thin polymer films.

Strain sensors have received considerable attention in personal healthcare due to their ability to monitor real-time human movement. However, the lack of chemical sensing capabilities in existing strain sensors limits their utility for continuous biometric monitoring. Although the development of dual wearable sensors capable of simultaneously monitoring human motion and biometric data presents significant challenges, the ability to fabricate these sensors with geometries tailored to individual users is highly desirable.

Aiming at the problems such as large dust in each production process of open-pit mines, insufficient water resistance of the curing layer of dust control materials, and poor mechanical strength, this research applied the network generated by Schiff base reaction between oxidized starch (OS) and gelatin (GEL) as the basis, and combined with polyvinyl alcohol (PVA) and calcium chloride (CaCl). This material improves the problem of poor dust suppression effect caused by the environment of open-pit coal mines. It was found that the large number of amino groups contained in GEL attack the carbon atoms in the carbonyl group of OS to form carbon-nitrogen double bonds, generating Schiff bases as the crosslinking network, which enhanced the water resistance of the polymers.
