Article Abstract
Deep eutectic solvents have attracted considerable attention due to their unique properties and their potential to replace conventional solvents in diverse applications, such as catalysis, energy storage, and green chemistry. However, despite their broad use, the microscopic mechanisms governing solvation dynamics and the role of hydrogen bonding in deep eutectic solvents remain insufficiently understood. In this article, we present our contributions toward unravelling the micro heterogeneity within deep eutectic solvents by combining vibrational Stark spectroscopy and two-dimensional infrared spectroscopy with molecular dynamics simulations. Our findings demonstrate how the composition, constituents, and addition of water significantly influence the heterogeneous hydrogen bonding network and solvent dynamics within these systems. These insights provide valuable guidance for the design of next-generation solvents tailored to specific applications. By integrating experimental and computational approaches, this work sheds light on the intricate relationship between solvation dynamics and nanostructure in deep eutectic solvents, ultimately paving the way for innovative advances in solvent design.

Worldwide, marine shell waste generated from the seafood industry has emerged as a significant environmental challenge. Indeed, this shell waste represents an abundant source of various valuable products, particularly chitin. However, the extraction and subsequent processing of chitin are hindered by the inherently resistant structure of these chitin-rich feedstocks, coupled with strong hydrogen bonding between chitin chains.

With the exhaustion of fossil fuels, prior phase change materials are characterized by such drawbacks as poor thermal conductivity, weak shape stability, and high costs. Therefore, the preparation of phase change materials with brilliant thermal-insulating properties, high thermal conductivity, and leakage-free properties has emerged as a crucial research focus. Herein, a sericultural mulberry branch-derived (SMB) composite phase change material was prepared by deep eutectic solvent pretreated SMB and vacuum-assisted impregnated paraffin wax with cupric oxide (CuO).

This study examined the effect of natural deep eutectic solvent (NADES) concentration on the kinetics of glucomannan swelling and deacetylation during the purification process and the characteristics of purified porang glucomannan (PGM). NADES was prepared from betaine and 1,2-propanediol (BPG14) at concentrations ranging from 30 % to 100 % (W/W). The deacetylation degree, along with the structural, thermal, and rheological properties of PGM, as well as the rate of glucomannan swelling and deacetylation, were investigated.

A one-pot strategy was developed to fabricate a strong and ductile elastomer composed of chitin nanocrystals and poly(deep eutectic solvent) (ChNC/PDES), based on a dual-network structure formed through glycidyl methacrylate (GMA)associated modification, polymerization and crosslinking. This approach enables the integrated pretreatment, chemical modification, and nanodispersion of chitin within a lactic acid/choline chloride deep eutectic solvent (DES) system. Whereafter, the ultraviolet initiated polymerization of GMA with ChNC and DES components produced a homogeneous elastomer with a maximum tensile strength of 4.
