Killing the bounce

Sprayed concrete is used in large quantities on major construction projects. As rebound during spraying results in loss of material and affects proper-ties, polymer additives were designed specifically to reduce this problem. Large-scale tests confirmed that adhesion to wet substrates, permeability and cracking could all be improved. The added costs can be more than offset by reductions in working time....

Mapping the route from wet to dry

An EC framework project known as NAPOLEON has been formed to investigate nanocomposites. The project has developed several new techniques to study drying of waterborne coatings, which is especially critical for nanocomposites. Ways to monitor stresses during drying, particle movements, changes in water concentration with depth, film structure and local variations in surfactant concentration are described....

Star performers

Control over protein adsorption and cell adhesion is necessary in technical processes such as water treatment, as well as high-end and academic applications such as bioanalytics or tissue engineering. Coatings prepared from end-functionalised six armed poly(ethylene oxide) based star molecules are shown to be highly effective for a range of biomedical applications
