The necessity of more sustainable conditions that follow the twelve principles of Green Chemistry have pushed researchers to the development of novel reagents, catalysts and solvents for greener asymmetric methodologies. Solvents are in general a fundamental part for developing organic processes, as well as for the separation and purification of the reaction products. By this reason, in the last years, the application of the so-called green solvents has emerged as a useful alternative to the classical organic solvents. These solvents must present some properties, such as a low vapor pressure and toxicity, high boiling point and biodegradability, and must be obtained from renewable sources. In the present revision, the recent application of these biobased solvents in the synthesis of optically active compounds employing different catalytic methodologies, including biocatalysis, organocatalysis and metal catalysis, will be analyzed to provide a novel tool for carrying out more ecofriendly organic processes.

Invasive surgical methods are the current standard for hemostasis and wound closure. In recent years, injectable hydrogels prepared from natural biomacromolecules have shown promise as tissue adhesives to overcome their shortcomings due to their high hydrophilicity and biocompatibility, but the inherent properties of unmodified biomolecules remain a major challenge in their application. In this paper, a hydrogel (DS/Gel-CDH) with self-healing, injectable and adhesive functions was constructed by Schiff base crosslinking between carbonyl hydrazide modified gelatin (Gel-CDH) and dialdehyde starch (DS).

Secondary salinisation significantly compromises soil quality because of the over-application of chemical fertilisers. The combined application of biochar and microorganisms enhanced soil physicochemical properties and improved soil remediation efficiency. However, different types of biochar had varying effects on microbial growth and reproduction.

Chitosan is a bio-based material that is more environmentally friendly than traditional petroleum-based materials, but its biofilms often suffer from brittleness and limited antioxidant and antibacterial properties. To overcome these challenges, chemically modified chitosan is a key solution. Herein, a novel CS-LA/CHA films were prepared through a radical reaction of chitosan (CS), lipoic acid/chalcone derivative (LA/CHA) and N,N-methylene bisacrylamide (MBA).
