Selected mono- and bicationic quats were compounded with polyethylene. The physicochemical surface properties, leaching behavior, and antibacterial activity of such modified samples were investigated. Contact angle measurements and fluorescein bindin

This article summarizes applications of sol-gel coatings to modify surface properties, and the process is illustrated with several examples. The use of azobenzene-modified silanes leads to a photoswitchable coating displaying light-controlled wettabi

A common phenomenon concerning cold surfaces which are subjected to a warmer, more humid atmosphere is condensation in the form of water droplets (fogging) or even ice crystals (icing). Thus, a previously transparent object becomes opaque because lig
The purpose of this study is to render polyethylene surfaces strongly and permanently hydrophobic. Polyethylene is a common plastic and, because of its inertness, difficult to graft. We chose polyethylene as example because of its ubiquity and model

Icing of wind turbines affects energy production, causes mechanical failures and increases safety hazards in general; hence there is an enormous demand for powerful anti-icing methods. To investigate the icephobic properties of different coatings, ic
A screening program to investigate the stability of plastics against wet abrasion was conducted. Plastic discs were spun in solvent/corundum suspensions at high speed and their wear was determined. Nine different plastics were investigated in water/c

The precipitation of calcium carbonate from hard water, commonly known as calcification or scaling, is a widespread nuisance. To avoid scaling, a physical or chemical pretreatment of water is often employed, such as ion exchange, addition of complexi

Treatment of lower order arylcyanocuprates ArCu(CN)Li with 1 equiv of an aryllithium (Ar'Li) at temperatures around -125 o C leads to higher order reagents Ar(Ar')Cu(CN)Li 2 . Upon exposure of such reagents at this temperature to ground-state molecul
