[Nature Chemistry] Photoswitching of Glass Transition Temperatures of Azobenzene-containing Polymers Induces Reversible Solid-to-liquid Ttransitions
The development of polymers with switchable glass transition temperatures (Tg) can address scientific challenges such as the healing of cracks in high-Tg polymers and the processing of hard polymers at room temperature without using plasticizing solvents. Here, we demonstrate that light can switch the Tg of azobenzene-containing polymers (azopolymers) and induce reversible solid-to-liquid transi...

Nature "Directional water collection on wetted spider silk" 2010, 463, 640 (Cover of Nature)
Here we show that the water-collecting ability of the capture silk of the cribellate spider Uloborus walckenaerius is the result of a unique fibre structure that forms after wetting, with the ‘wet-rebuilt’ fibres characterized by periodic spindle-knots
made of random nanofibrils and separated by joints made of aligned nanofibrils. These structural features result in a surface energy g...

On the nature of the bubble velocity discontinuity in non-Newtonian fluids
The motion of single air bubbles in non-Newtonian fluids was investigated. Depending on the rheological properties of the fluid (viscoelasticity, shear thinning), a discontinuity of the bubble velocity can be observed.
