[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.

Nature Communications——Transformable masks for colloidal nanosynthesis
Synthetic skills are the prerequisite and foundation for the modern chemical and pharmaceutical industry. The same is true for nanotechnology, whose development has been hindered by the sluggish advance of its synthetic toolbox, i.e., the emerging field of
nanosynthesis. Unlike organic chemistry, where the variety of functional groups provides
numerous handles for designing chemical select...

(Nature) Directional Water Collection on Wetted Spider Silk
Many biological surfaces in both the plant and animal kingdom possess unusual structural features at the micro- and nanometrescale that control their interaction with water and hence wettability1–5. An intriguing example is provided by desert beetles,
which use micrometre-sized patterns of hydrophobic and hydrophilic regions on their backs to capture water from humid air6. As anyone wh...
