Summary: Biopolymers, especially cellulose, play a vital role in transitioning to a circular economy and reducing reliance on fossil fuels. However, modifying cellulose hydroxyls is a challenge due to the similarity of their chemical features with water. To address this, we developed bio-based ionic liquids that can activate cellulose without disturbing its crystalline ordering. One specific ionic liquid showed high activation in heterogeneous conditions, resulting in over 30% conversion of cellulose hydroxyls. This work opens new perspectives for cellulose derivatization while maintaining sustainability.

Summary: Currently, there are concerns about the non-recyclability of epoxy resins in the market, as well as their synthesis via petroleum-based raw materials which limit their usage. Therefore, finding environmentally friendly alternatives for epoxy formulation is crucial. This paper explores a Cradle-to-Cradle approach to ensure the infinite reuse of epoxy resins, starting with a fully recyclable bio-based epoxy formulation and obtaining a recycled polymer that can be mixed with the same formulation. The approach provides a sustainable disposal route for epoxy resin and offers a green component for the primary bio-based epoxy matrix.

Summary: A new approach using mixtures of triphenylphosphine dichloride or oxalyl chloride and hydrogen peroxide in organic solvents was developed for the rapid dissolution of elemental noble metals (NMs). Almost complete dissolution of gold, palladium, and copper was observed within minutes at room temperature. This method has potential applications in the hydrometallurgical leaching and purification of NMs from ores, spent catalysts, and electronic and nano-wastes.

Summary: Plastics waste is increasing due to the global rise in plastic production and consumption. Traditional methods for degrading plastics waste require high temperatures and pressures, but ionic liquids (ILs) are being researched as a more environmentally friendly alternative. ILs have unique properties that enable them to degrade plastics under less harsh conditions and can also be easily separated and reused.

Summary: In this study, a binary system of IL-OH and IL-Ester ionic liquids (ILs) was prepared and characterized. The physico-chemical properties such as density, viscosity, thermal stability, and refractive index were determined for the binary system. The addition of IL-Ester increased the viscosity and refractive index, while decreasing the density and thermal stability. The study also provided insights into the mixing behavior and interactions among these binary mixtures.

Summary: Until recently, reuse models for food packaging plastics were considered burdensome but now they are placed second in the waste management hierarchy of the plastics circular economy. This study evaluates the safety and structural integrity of biobased and biodegradable materials, PHBV and PHBV-quercetin, in different reuse scenarios. The results show that PHBV material can undergo a full reuse cycle and withstand multiple washing cycles without significant degradation, while the use of quercetin as an additive may accelerate material degradation during washing steps.

Summary: This study compared different life cycle stages of the red alga Gracilaria dura, focusing on morphological structures, growth performance, agarose characteristics, biochemical, and molecular profiling. Significant differences were found in growth rates and agarose yield among male gametophytes, tetrasporophytes, and cystocarpic female gametophytes. Metabolomic analysis revealed critical differences in alanine, lactate, and isethionic acid among stages, while genetic correlation analysis showed an average polymorphism of 47.02%. The study concludes that characterizing and differentiating isomorphic life phases of G. dura could be valuable for selecting appropriate cultivars for commercial farming and breeding programs.

Summary: The existence of numerous biomolecules in biological fluids leads to the phenomenon of macromolecular crowding, which is essential to maintain the active conformation of proteins. In this study, double helical DNA is used as a biomacromolecular crowding system to package cytochrome c (Cyt C), resulting in significantly enhanced catalytic activity and stability. The main interactions between DNA and Cyt C are electrostatic and hydrogen bonding. Furthermore, DNA-based macromolecular crowding media can effectively stabilize proteins against various stresses.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
