A facile, environmentally friendly, and low-cost strategy for affording stability and the slow-release of avermectin based on self-assembly of lignin derivatives is described.

A facile and versatile approach to constructing colorless surface coatings based on green tea polyphenols is reported, which can further act as a photoinitiating layer to initiate radical polymerization. These colorless green tea polyphenol coatings are capable of successfully photografting polymer brushes, and the resulting polymer brush patterns show spatial shape adjustability by masked UV irradiation. Both surface modifications and photografted polymer brushes do not alter the original color of the substrates. This method could be promising for the development of surface modifications.

There has been an ongoing interest in using proteins as more environmentally friendly substitutes for the existing synthetic adhesives. Poor water resistance is a particular shortcoming of protein-based adhesives, which negatively affects their outdoor functionality. In this study, we systematically investigated if water solubility of the protein, addition of a phenolic compound such as tannic acid, and protein–polyphenol complexation could improve the water resistance of protein-based adhesives. It was found that the synergetic effects of these parameters can yield commercial-level water resistance.
