11. Tailoring residue-derived carbon materials for the removal of wastewater contaminants : adsorption and surface properties
Abstract : The availability of effective, low-cost wastewater treatment is necessary for increased water recycling and the prevention of environmental pollution on a global scale. Adsorption on activated carbons is commonly applied in wastewater treatment, but the high cost of conventional activated carbons limits the use of this technique. READ MORE

12. Hydrophobic Impregnation of Concrete Structures : Effects on Concrete Properties
Abstract : Hydrophobic impregnations often referred to as water repellent agents, today mainly consisting of alkylalkoxysilanes, are often used on concrete to prolong the service life of the structure. This is accomplished by protecting the reinforcement bars from chlorides or by changing the moisture content inside. READ MORE

13. Interfacial Properties of Biomacromolecular Model Systems: Surface Forces and Nanotribology
Abstract : The nanotribology, adhesion and related interfacial properties of biomacromolecular systems have been studied. The aim was to elucidate the role of physisorbed and chemically grafted bio-polymers implicated as mediators for cellulose based processing and material design. READ MORE

14. Toward Anti-icing and De-icing Surfaces : Effects of Surface Topography and Temperature
Abstract : Icing severely affects society, especially in the Nordic countries. Iceaccumulation can result in critical performance problems and safetyconcerns for instance in road, air and sea transportation, transmissionlines, marine and offshore structures, wind turbines and heat exchangers.

15. Tribology of stamping : the influence of designed steel sheet surface topography on friction
Abstract : Tribology is the science of friction, wear, and lubrication; the interaction of surfaces in relative motion. The tribological conditions in sheet metal forming influences the flow of material in forming operations, the strain distributions of sheet material, extent of wear, and thereby the quality of products.
