Scaling to new heights with gecko-inspired adhesive

12-Jan-2018

Some animals, such as geckos, can easily climb up walls and across ceilings. But currently, no material exists that allows everyday people to scale walls or transverse ceilings as effortlessly. Now, scientists report a dry adhesive that could someday make it easier to defy gravity. Geckos can ...

New microscope sets a record for visualizing surface wetting properties

29-Nov-2017

Wetting is an everyday phenomenon that represents how well liquid spreads on a surface. When water comes into contact with an extremely water-repellent, or 'superhydrophobic' surface, droplets bead up and roll off easily. Aalto University researchers have developed a measurement technique called ...

Fire and flame for new surfaces

04-Nov-2016

The printing, coating and bonding of plastics requires the surface to be pre-treated. Flame treatment is one way to achieve this so-called activation. It is currently being used in many industrial sectors and has considerable potential for development. The Fraunhofer Institute for Applied Polymer ...
