With the development of self-healing materials and increasing demands from complicated application environment, underwater is attracting more attention. However, until now, effects different dynamic chain extender water molecular on polyurethanes have not been investigated yet. In this work, we synthesized two types with 2,4-pentanedione dioxime (DMG) bis(4-hydroxyphenyl) disulfide (HPS) as ext...

Highly efficient and eco-friendly antimicrobial agents are crucial to the development of future marine antifouling coatings. A high low bio-toxicity bio-based anti-biofoulant, 2,5-diformylfuran dioxime chelating with copper ions (E-DFFD-Cu), is evaluated. Its minimal bactericidal concentration for 50% maximal effect (EC50) 4.95 7.03 µmol L−1, respectively. Excellent anti-biofouling performance ...

2,5,10,13-tetraazatricyclo [12,2,2,26,9] icosa-1(16),6,8,14,17,19-hexene-3,4,11,12-tetraone tetraoxime (1a) and 2,5,11,14-tetraazatricyclo [13,3,1,16,10] icosa-1(19),6,8,10(20),15,17-hexaene-3,4,12,13-tetraonetetraoxime (1b) were obtained from condensation of 1,4- and 1,3-phenylendiamine with dichloroglyoxime, respectively. the reaction of 1,2-phenylendiamine with dichloroglyoxime resulted in t...

The herbal market is flooded with substitutes and adulterants due to non-availability of the genuine drug and poor knowledge and difficulty in identifying the pure active principle. Toddalia asiatica (Rutaceae) is a constituent of traditional systems of medicine used for treating a paradigm of diseases. The flowers were extracted with methanol, the filtered extract was concentrated to dryness a...
