Previously we discovered that OmpA of Escherichia coli increases biofilm formation on polystyrene surfaces (González Barrios et al., Biotechnol Bioeng, 93:188-200, 2006a). Here we show OmpA influences biofilm formation differently on hydrophobic and hydrophilic surfaces since it represses cellulose production which is hydrophilic. OmpA increased biofilm formation on polystyrene, polypropylene, ...
A nanocomposite adsorbent based on potassium nickel hexacyanoferrate-loaded polypropylene fabric was synthesized for selective removal of Cs ions from contaminated waters by a two-stage synthesis: radiation-induced graft polymerization of acrylic acid monomer onto the nonwoven polypropylene fabric surface with subsequent in situ formation of potassium nickel hexacyanoferrate (KNiHCF) nanopartic...
BACKGROUND Large defects of the abdominal wall caused by incisional hernia still represent a challenging problem in plastic, reconstructive, and abdominal surgery. For their successful tension-free repair a proper selection of reconstructive material is essential. In the last decades, the use of synthetic meshes was dominant while biological autodermal grafts were rarely used. The aim of the st...
Microplastics (MPs) affect plankton (a basis of the trophic chain) and planktivorous fish can ingest them through food confusion or by transmission. Consensus to determine MPs in is lacking and, so, three digestion treatments were evaluated: Alkaline (potassium hydroxide) enzymatic (protease plus lipase) digestions, both combined with a hydrogen peroxide stage; an oxidative method using surfact...
The impact of a small amount polystyrene-b-poly(ethylene-co-butylene)-b-polystyrene (SEBS) on the thermomechanical and electrical properties blends comprising low-density polyethylene (LDPE) isotactic polypropylene (PP) is investigated. SEBS found to assemble at PP:LDPE interface as well within isolated PP domains. addition 10 wt% significantly increases storage modulus between melting temperat...
