Abstract Aminated tannins were prepared by reacting mimosa condensed tannin extract with ammonia yielding the substitution of many, if not all of the tannin hydroxyl groups with –NH₂ groups. A tannin-aminated tannin (ATT) particleboard coating was then prepared by reacting raw tannin extract with aminated tannin extract and thus cross-liking the two by substituting tannin’s hydroxyl groups with the –NH₂ groups on the aminated tannin to form –NH-bridges between the two. The resulting particleboard coating gave encouraging results when pressed at 180°C for 3 min. Conversely, the system in which tannin was reacted/cross-liked with urea (ATU) by… More >

Abstract Coronaviruses are responsible for a developing budgetary, human and fatality trouble, as the causative factor of infections, for example, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It has been well recognized that SARS-CoV-2 may survive under severe atmosphere circumstances. Hence, efficient containment approaches, for example, sanitizing, are crucial. Commonly, living compounds contribute a substance of chemical heterogeneity, with antiviral movement, and therefore can have efficacy as therapeutic tools toward coronavirus diseases. Here, in this review article, we have described the antimicrobialbased materials, which can be used to inhibit the spreading of the COVID-19. We have More >
