Photocuring Systems Using Quaternary Ammonium Thiocyanates.

Testing quaternary ammonium germicides.

Towards antibacterial endodontic sealers using quaternary ammonium nanoparticles.

AIM To change and characterize the antibacterial properties of endodontic sealers by incorporating low concentrations of insoluble antibacterial nanoparticles (IABN). METHODOLOGY The antibacterial effect against Enterococcus faecalis was evaluated by (i) agar diffusion test (ADT), (ii) direct contact test (DCT) and (iii) scanning electron microscopy (SEM). IABN were incorporated into AH Plus ...

Electrochemical recognition of charged species using quaternary ammonium binaphthyl salts.

The effects of ionic analytes on the electrochemical properties of quaternary ammonium binaphthyl salts are described in this work. The stability of the binaphthyl radicals and hence the reversibility of the electrochemical response are discussed in terms of molecular structure. The ability of azacrown derivatised binaphthyl salts to act as amperometric receptors is ascribed to the strain impar...
