Summary: The efficient separation of 5-HMF from DESs was achieved by four cycles of extraction using THF, with an overall extraction efficiency of more than 80.0% (30 degrees C). Additionally, the addition of 1 mol L-1 NaCl solution significantly improved the extraction efficiency from 30.0% to 42.0%. Furthermore, the recovery and reuse of the extractant proved to be effective, with a purity of 90.0% for 5-HMF in the recovered product and 97.0% THF in the recycled extractant. This study demonstrates an efficient and environmentally friendly method for separating and recovering 5-HMF while ensuring the reuse of the extractant.

Summary: Paramylon is a water insoluble linear glucan produced by Euglena gracilis microalgae. It has a stable triple helix conformation and high crystallinity due to its macromolecular structure containing only b(1-3) linkages. The solubility of paramylon was evaluated using eco-friendly ionic liquids as solvents, and the structure and thermal properties of the biopolymer before and after solubilization and regeneration were discussed.

Summary: This study investigated the mechanism of cellulose regeneration in ionic liquids (ILs) through molecular dynamics (MD) simulations. The results showed that the concentration of anti-solvents affects the number of hydrogen bonds in cellulose chains, with water having a positive impact on cellulose regeneration. Additionally, the interaction energy between cellulose and the anions of ILs was found to be stronger than that between cellulose and the cations.

Summary: In this study, 56 deep eutectic solvents (DESs) were prepared and applied to dissolve lignocellulosic components. It was found that the structures of DESs significantly affected the Kamlet-Taft parameters. The correlation between Kamlet-Taft parameters and solubility varied with DESs and lignocellulosic components. DESs with greater values of β and β-α (net basicity) were expected to efficiently dissolve cellulose, while those with greater net basicity were favorable for dissolving lignin. The solubility of xylan was linearly correlated with the β value. These findings provided valuable information and necessary theoretical guidance for designing robust DESs to dissolve lignocellulosic components based on Kamlet-Taft solvatochromic parameters.

Summary: The use of carbohydrate polymer-modified carbon allotropes (CPMCAs) as nanofillers in reinforced polymer-composite coatings is an eco-friendly and cost-effective approach. CPMCAs offer numerous essential features such as high surface area, uniform distribution, self-healing properties, high durability, long-term protection, and optimized hydrophilicity, making them ideal substitutes for traditional toxic nanofibers. They prevent the diffusion of corrosive species and their galvanic coupling with metal/alloy surfaces, magnifying their anticorrosive potential and fulfilling the requirements of self-healing coatings.

Summary: By changing the electron density at donor sites, substituents significantly impact the coordination proficiency of organic inhibitors, either through inductive or resonance effects. The effect of substituents on the inhibition potential varies depending on their location. Resonance effects of polar substituents enhance the inhibition effect, while electron-withdrawing substituents may decrease inhibition efficiency, although they can enhance solubility in polymers.

Summary: Heterocyclic compounds containing nitrogen atoms have excellent corrosion inhibition potential and are frequently used to prevent corrosion in extreme circumstances. These compounds can effectively adsorb on the metal's surface and form chelating complexes to protect metallic species from corrosive environments. Azoles and triazines, as well as other N-heterocyclic compounds with multiple nitrogen atoms, are particularly efficient in reducing corrosive effects in aqueous electrolytes. This review discusses the coordination and bonding characteristics of N-based heterocyclic compounds and their ability to prevent corrosion.

Summary: In this study, Oregano (Origanum vulgare) leaf essential oil was investigated as an environmentally friendly corrosion inhibitor for carbon steel in hydrochloric acid. The corrosion inhibition mechanism was studied through surface morphology analysis, electrochemical tests, weight loss measurements, theoretical calculations, and computational methods. The results showed that O. vulgare had the highest inhibition performance of 85.64% at a concentration of 2 g/l in 1 M HCl. The adsorption of the O. vulgare inhibitor on the metal surface was attributed to the formation of rigid covalent bonds, and the hydroxyl functional groups and benzoyl rings were found to be the main contributors to the high inhibition efficiency.
