A novel type of fabric that can absorb water and perspiration on one side and transport it to the other has been invented by a team of textile scientists based at The Hong Kong Polytechnic University (PolyU). The finding was published in the latest issue of the Journal of Materials Chemistry (Issue dated 13 October 2011) of the Royal Society of Chemistry.
This ground-breaking research was done by Professor John Xin, Acting Head of PolyU’s Institute of Textile and Clothing; his PhD student Miss Kong Yee-yee; and Dr Liu Yuyang of the Stevens Institute of Technology in the US. The researchers have made the fabric hydrophilic on one side by coating it with nano titania, which gives the material photo-induced hydrophilicity. This means that its hydrophilicity can be controlled by light. The fabric becomes hydrophobic after being stored in the dark.
The fabric could be used to wick sweat away from the human skin. In the light, water can be transported in a controllable manner from the hydrophobic side (next to the skin) to the hydrophilic side and then spread out rapidly along the channels on the hydrophilic side.
This differs from other materials that do a similar thing. Current materials work by creating a surface energy gradient across the fabric by a pressure difference. Professor John Xin’s work introduces nano and smart elements into the system, taking advantage of titania’s properties.
A pioneering researcher, Professor John Xin and is renowned for his nano-technology breakthrough for to develop a special fabric which can be made into self-cleaning clothes. This breakthrough by Professor Xin and Dr Walid Daoud in 2004 was also reported by Nature.

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
