Im Empa-Kolloquium werden aktuelle Themen aus den Bereichen der naturwissenschaftlich-technischen Wissenschaften, insbesondere auch aus den Forschungsschwerpunkten der Empa aufgegriffen. Die Vorträge bewegen sich auf hohem wissenschaftlichem Niveau und sprechen eine breite, interdisziplinäre Zuhörerschaft an. Das Empa-Kolloquium dient der Horizonterweiterung der wissenschaftlichen MitarbeiterInnen, insbesondere der DoktorandInnen.
Greenland ice sheet and dynamic response to global warming
The ice loss in Greenland shows acceleration during the last decade. WSL director Konrad Steffen explains how scientists gained new insight using ground penetrating radar and a video system during the melt peak in August 2007-2010. Water penetrates to great depth through moulins and cracks, lubricating the bottom of the ice sheet.
The energetics of nanomaterials are typically dominated by (excess) surface and/or interface energy contributions. In his talk, Dr. Lars Jeurgens from Empa, addresses recent advances in the thermodynamic description of reactions and phase transformations in nanomaterials.

Bio-inspired micropatterned surfaces with new adhesive functions
3D-micropatterning of surfaces signifies a recent paradigm change for control of surface functionalities: the exploitation of cleverly designed surface protrusions at the micron scale. In his talk Prof. Eduard Arzt from the Leibniz Institute for New Materials / Saarland University, Saarbrücken, summarizes recent developments in producing bio-inspired micropatterned polymer surfaces.
Energy Efficiency in a Growing Economy: Curse or Blessing?
Energy efficiency is a key element of many energy and environmental policies. Despite autonomous and forced improvements in energy efficiency, however, in most countries overall energy consumption has not decreased. Reinhard Madlener from RWTH Aachen explains how «rebound effects» emerge and influence further development.
