Cells of dichloromethane (DChM) bacteria-destructors were immobilized by sorption on different types of membranes, which were fixed on the measuring surface of a pH-sensitive field transistor. The presence of DChM in the medium (0.6-8.8 mM) led to a change in

The phytoalexin cyclobrassinin is a plant defense that has additional importance since it inhibits brassinin hydrolase, a phytoalexin detoxifying enzyme produced by the plant pathogen Alternaria brassicicola. Hence, the 1,3-thiazino[6,5-b]indole scaffold of cyclobrassinin has great application as a lead structure

Aromatic difluoroboron β-diketonate complexes (BF2bdks) are classic fluorescent molecules that have been explored as photochemical reagents, two-photon dyes, and oxygen sensors. To gain a better understanding of their emissive properties in both solution and polymer matrices, BF2bdks with varying aromatic
