Abstract:: ... Antibacterial polymers suitable for coating applications without leaching of the biocidal component have been obtained by UV copolymerization of acrylic resins with acrylic monomers containing quaternary ammonium moieties. Suitable reactive biocides, based on quaternary ammonium monomers (QAMs), endowed with undecylacryloyl group and alkyl chains with 2 (QAM-C2), 8 (QAM-C8), and 16 (QAM-C16) carbo ...

Abstract:: ... Oxidative transformation of tyrosol catalysed by Trametes trogii laccases in aqueous solution was investigated. LC–MS analysis shows that tyrosol was converted to its dimer. The enzymatic reaction was also investigated by 1H and 13C nuclear magnetic resonance, and the product formed was identified as a dimeric tetracyclic ketone. The bactericidal and fungicidal properties of tyrosol dimer were inv ...

Abstract:: ... The degradation of two organic pollutants (amoxicillin and diclofenac) in 0.1 mM aqueous solutions was studied by using advanced oxidation processes, namely ozonation, photolysis, photolytic ozonation, photocatalysis and photocatalytic ozonation. Diclofenac was degraded quickly under direct photolysis by artificial light (medium-pressure vapor arc, λexc > 300 nm), while amoxicillin remained very s ...

Abstract:: ... Due to the increasing occurrence and spread of antibiotic resistance pathogenic microorganisms, the development of antimicrobial materials has emerged as a strategy to control the bacterial activity and transmission. In this study, poly(vinyl alcohol)/silver nanoparticles-graphene oxide (PVA/AgNPs-GO) nanocomposites were synthesized by a one-step process with l-ascorbic acid as environmentally fri ...

Abstract:: ... The structure of aqueous solution surfactants, particularly the spacer group used to link the polar head groups, can significantly affect its surface activities and application properties. Herein, we designed and synthesized cationic gemini surfactants (i. e., CₙDBH, n = 12, 14, 16, 18) with biphenyl and multiple amide groups as rigid spacer and characterized their structures using ¹H NMR, ¹³C NMR ...
