Summary: In this study, a glutaraldehyde-assisted crosslinking strategy was developed to prepare crosslinked regenerated cellulose (CRC) films, and the effects of different crosslinking methods on the dielectric and mechanical properties of the films were investigated. The CRC films showed reduced defects and enhanced intermolecular interaction compared to common RC films. With a glutaraldehyde concentration of 6 vol% and a crosslinking time of 30 min, the CRC film exhibited the lowest dielectric loss and the highest breakdown strength, as well as high tensile strength and excellent tensile modulus. This work provides new insights for tailoring the properties of cellulose films and has significant implications for the fabrication of high-performance cellulose-based dielectric materials.

Summary: Gamma irradiation was used to induce the hydrogelation of silk fibroin, and the characteristics of the irradiation-induced hydrogels were investigated. The irradiation-induced hydrogels exhibited better thermal stability and contained more random coil structures and fewer beta-sheet structures. This finding suggests that the gelation mechanism induced by gamma irradiation may differ from the established mechanism. The study also demonstrates that gamma irradiation can be used as an alternative method to produce chemical-free, random coil-rich, and sterilized silk fibroin hydrogels for biomedical applications.

Summary: This paper studies the control, improvement, and correlation of the mechanical and dielectric properties of SEBS and SEBS-MA by using graphite as filler in various concentrations. The results show that the real permittivity increases exponentially with the concentration of graphite, and the dielectric losses are low with high stability at high graphite content. Additionally, an increase in graphite content also leads to an increase in the mechanical stiffness of the composites.

Summary: Cellulose, the most abundant and green biomass resource on earth, has gained significant attention as an alternative to traditional chemical and petroleum resources. This review discusses the various solvents used in industrial processes, including traditional solvents, non-derivative organic solvents, and aqueous solution systems, as well as their dissolution mechanisms and advancements in fiber-spinning processes. The challenges associated with industrial production of viscose fibers and cuprammonium fibers are also addressed. The focus of this paper is on the research status of regenerated cellulose fibers (RCFs) prepared using environmentally friendly and non-polluting aqueous solutions, and it provides strategies and methods for improving the mechanical strength of RCFs and facilitating industrial production. Finally, the current developments of RCFs are summarized and future research directions are proposed, serving as a guide for the future trends in RCFs.

Summary: Diabetes is a global problem that can affect people of all ages. Diabetic retinopathy (DR) is a major eye condition resulting from diabetes, which, if not detected and treated in time, can lead to vision loss. Manual examination by experts is currently the time-consuming process of detecting and monitoring DR. The identification of retinal vasculature, as well as segmentation of the optic disc (OD)/fovea, plays a crucial role in DR detection. Advancements in artificial intelligence (AI) and specifically in deep learning (DL) have led to their widespread use in DR-related studies. In this study, we review the latest literature on DR segmentation and lesion detection from fundus images using DL.
