Dual antibacterial effect of immobilized quaternary ammonium and aliphatic groups on PVC [PDF]

open access: yes, 2015
A coating comprising quaternary ammonium salts (QAS) and aliphatic moieties was formed on the poly(vinyl chloride) (PVC) surface in order to confer antibacterial activity. This was achieved by grafting mercaptopropyltrimethoxysilane onto PVC, followed by

(2S,NS)-N-Allyl-N-benzyl-1-hydroxy-3-(4-hydroxyphenyl)-N-methylpropan-2-aminium bromide

open access: yesActa Crystallographica Section E, 2008
The title compound, C20H26NO2+·Br−, is an N-chiral quaternary ammonium salt synthesized from (2S*)-N-benzyl-N-methyltyrosine methyl ester. The dihedral angle between the phenyl ring and the benzene ring is 11.61 (19)°.

Transcriptome analysis of Listeria monocytogenes exposed to biocide stress reveals a multi-system response involving cell wall synthesis, sugar uptake, and motility [PDF]

open access: yes, 2014
peer-reviewedListeria monocytogenes is a virulent food-borne pathogen most often associated with the consumption of “ready-to-eat” foods. The organism is a common contaminant of food processing plants where it may persist for extended periods of time.

A Most Unusual Zeolite Templating: Cage to Cage Connection of One Guest Molecule [PDF]

open access: yes, 2010
An unusual case of a diquaternary ammonium dication, with large bulky end groups built from the tropane moiety and connected by a C4 methylene chain, is found to reside in zeolite SSZ-35 (STF).
