Antibacterial activity of pyrrolidine dithiocarbamate [PDF]

FEMS Microbiology Letters, 2008
Pyrrolidine dithiocarbamate (PDTC), an antioxidant with a metal-chelating activity, has been used widely to inhibit the expression of inflammatory genes in vitro and in vivo. This study investigated whether PDTC has an antimicrobial activity against various bacteria.

Dynamic Defect Tolerance in Metal Halide Perovskites: From Phenomena to Mechanism

Advanced Energy Materials, EarlyView.
Defect tolerance is the key feature that dominates the high performance of perovskite devices. MHPs exhibit dynamic defect tolerance at practical working condition, which is intrinsically relevant to their soft‐lattice thus mixed ionic‐electronic conduction, and intimately correlated with charge carrier, phonon, lattice, and mobile ions and determine ...

Engineering Bodipy‐Based Metal–Organic Frameworks for Efficient Full‐Spectrum Photocatalysis in Amide Synthesis

Angewandte Chemie, EarlyView.
Three highly stable bodipy‐based metal–organic frameworks (BMOFs) were synthesized by treating dicarboxyl‐functionalized bodipy ligands with Zr‐oxo clusters. Featuring the distinct bodipy scaffold in the framework, these BMOFs displayed high reactivity in heterogenous photocatalytic C─H bond activation of N,N‐dimethylanilines to access amides under ...

Mechanism of Cationic Peptide‐Induced Assembly of Gold Nanoparticles: Modulation of Electrostatic Repulsion

Aggregate, EarlyView.
Cationic peptides aggregate citrate‐capped gold nanoparticles (AuNPs), producing a colorimetric change. The figure highlights the interplay between the intermolecular attractive and repulsive forces governing the colloidal stability of the nanoparticles.

Preparation of Thermally and Photochemically Immobilized N‐type Conjugated Polymer Films via Quantitative Backbone Editing

Angewandte Chemie, EarlyView.
A postpolymerization modification (PPM) of n‐type conjugated polymers by nucleophilic aromatic substitution is reported, enabling precise tuning of solubility, ordering, and stability. The method allows the facile introduction of azide groups, which can undergo UV‐ or thermally induced crosslinking, to afford stable, insoluble films with retained ...
