With the risks associated with healthcare-associated infections and the rise of antibiotic resistant microorganisms, there is an important need to control the proliferation of these factors in hospitals, retirement homes and other institutions. This work explores the development and application of a novel class of sulfonamide-based quaternary ammonium antimicrobial coatings, anchored to commercially and clinically relevant material surfaces. Synthesized in high yields (60-97%), benzophenone-anchored antimicrobials were spray-coated and UV grafted onto plastic surfaces, while silane-anchored variants were adhered to select textiles dip-coating.

This paper proposes a facial expression recognition system using evolutionary particle swarm optimization (PSO)-based feature optimization. The system first employs modified local binary patterns, which conduct horizontal and vertical neighborhood pixel comparison, to generate a discriminative initial facial representation. Then, a PSO variant embedded with the concept of a micro genetic algorithm (mGA), called mGA-embedded PSO, is proposed to perform feature optimization.

A series of HO and/or EtOH soluble, self-assembling quaternary ammonium salts containing a dansyl (DNS) fluorescent moiety suitable for attachment to both porous ([DNS-NH-(CH)-NMe-R][X] (2; R = -Si(OMe), X = Cl) and non-porous (3a; R = -PO(OEt), 3b; -PO(Oi-Pr), 3c; -(PO(OH), X = Br), 4; ([DNS-NH-(CH)-NMe-(CH)-NH(CHPO(OEt)) ][Br], 5; R = -((CH)SCOCH, X = Cl), 6a; (R = -(CH)O(CH)CO(CH), n = 3, X = Br, 6b; n = 3, X = Cl, 6c; n = 3, X = I, 6d; n = 4, X = Br, 6e; n = 4, X = I, 6f; n = 6, X = Br, 6g; n = 6, X = Cl, 6h; n = 6, X = I), 7; (R = -CH-CH[double bond, length as m-dash]CH, X = Br) surfaces were prepared from the precursor dansyl amine (1; DNS-NH-(CH)-NMe). Compounds 1-7 were characterized by NMR (H, C, Si (2), P (3a-c, 4)) spectroscopy, HRMS, UV-Vis and fluorescence spectroscopy. Additional characterization of compounds 1 and 7 were carried out by X-ray structure determinations.
