Summary: The search for new analytical methods in green analytical chemistry aims to address environmental issues. Green solvents, particularly deep eutectic solvents (DESs), have been identified as promising substitutes for dangerous organic solvents. This study investigated the physical-chemical and ecotoxicological properties of seven different DESs and found that their properties are influenced by the chemical structure of their precursors. These findings provide new insights into the conscious usage of DESs in green analytical chemistry.

Summary: Adding low concentrations of nano-SiO2 can significantly improve the thermal stability of films based on sodium alginate, while concentrations above 1.0% may lead to agglomeration of the nanomaterial. Mechanical properties are reduced at concentrations of 1.0% and 1.5%, but water vapor and light barrier properties remain relatively unchanged.

Summary: Polybenzopyrrole synthesized in surfactant-supported acidic medium showed significantly enhanced thermal stability and electrochemical properties, with a maximum specific capacitance of 166.0 +/- 2.0 F g(-1) and excellent cycle stability of 87% after 5000 cycles at a current density of 1 A g(-1). The results suggest that polybenzopyrroles are competitive electrode materials for next-generation Faradaic supercapacitors, with high-power density and energy density. The findings of this study can also be easily applied to other systems for the synthesis of advanced hybrid/composite Pbp-based electrode materials.

Summary: This study investigated the effects of Deep Eutectic Solvents (DES) on the structure of cellulose fibers, focusing on the induced fibrillation phenomena. The results showed that DES treatment could enhance the mechanical properties of resulting papers without significantly modifying the chemical composition, crystallinity, and degree of polymerisation of cellulose. This suggests that DES treatment can be considered as a soft and green chemical refining method for cellulose microfibrillation.

Summary: Novel deep eutectic solvents were synthesized using 2-(methylamino)ethanol as hydrogen bond donor with different hydrogen bond acceptors. The physicochemical properties of these solvents were measured and compared with predicted values using mathematical models. The results showed that some models are suitable for predicting certain properties, but not accurate for others.

Summary: A new concept of green solvents called superlong supercooling solvents (SSSs) is proposed, which are metastable liquid solvents that can be used at temperatures around or slightly higher than room temperature before condensing after a superlong time. SSSs can serve as green alternatives to water, supercritical fluids, ionic liquids, and deep eutectic solvents (DESs).

Summary: Cellulose is an excellent candidate for sustainable materials with its good availability, renewability, biodegradability, and biocompatibility. However, its poor solubility in water and common organic solvents restricts chemical modification to heterogeneous conditions or limited systems. Recent advancements in green solvents have enabled more efficient and sustainable chemical modification of cellulose.

Summary: Research shows that chitosan, a strong and workable derivative of chitin obtained from crustaceans, can be used as a renewable alternative to fossil-fuel-based polymer materials. By adding different types of green additives, chitosan-based composites with various properties, from very hard and brittle to soft and flexible, have been successfully produced. These findings open up possibilities for adjusting the properties of chitosan-based polymer materials and applying them in consumer goods.

Summary: Zinc oxide nanorods were developed on stainless steel and glass substrates using spray pyrolysis and chemical bath deposition techniques. After exposure to shock waves, the nanorods exhibited sustainable surface morphology and crystalline quality, attributed to their slantly overlapped morphology and high melting temperature.
