NIR-II absorption and photothermal conversion in a photochromic metal-organic framework based on -2,2'-biquinoline-4,4'-dicarboxylate.

A BCA -coordinated MOF (1) was initially discovered to exhibit electron transfer photochromism. Remarkably, the photogenerated radicals (1P) showed a maximum absorption enhancement peak at 1158 nm, resulting from the synergistic effects of planar π-conjugation induced by -coordination and π-π interactions among [BCA]˙˙ radicals, thereby promoting the NIR-II photothermal effect.

c-di-GMP phosphodiesterase ProE interacts with quorum sensing protein PqsE to promote pyocyanin production in .

The universal bacterial second messenger bis-(3'-5')-cyclic dimeric guanosine monophosphate (c-di-GMP) plays critical roles in regulating a variety of bacterial functions such as biofilm formation and virulence. The metabolism of c-di-GMP is inversely controlled by diguanylate cyclases (DGCs) and phosphodiesterases (PDEs). Recently, increasing studies suggested that the protein-protein interactions between DGCs/PDEs and their partners appear to be a common way to achieve specific regulation.

Inhibiting NLRP3 enhances cellular autophagy induced by outer membrane vesicles from .

The bacterium is able to invade lung epithelial cells and survive intracellularly.

Photochemistry of Microsolvated Nitrous Acid: Observation of the Water-Separated Complex of Nitric Oxide and Hydroxyl Radical.

The photochemistry of nitrous acid (HONO) plays a crucial role in atmospheric chemistry as it serves as a key source of hydroxyl radicals (OH) in the atmosphere; however, our comprehension of the underlying mechanism for the photochemistry of HONO especially in the presence of water is far from being complete as the transient intermediates in the photoreactions have not been observed. Herein, we report the photochemistry of microsolvated HONO by water in a cryogenic N matrix. Specifically, the 1:1 hydrogen-bonded water complex of HONO was facially prepared in the matrix through stepwise photolytic O oxidation of the water complex of imidogen (NH-HO) via the intermediacy of the elusive water complex of peroxyl isomer HNOO.
