Scientists grow 'sea urchin'-shaped structures

Swiss researchers have succeeded in growing sea-urchin shaped nanostructures from minute balls of polystyrene beads using a simple electrochemical process. The spines of the sea urchin consist of zinc oxide nanowires. The ...

Carbon dioxide to methanol conversion

NUS chemists have developed a highly efficient nanostructured catalyst based on zinc and silver that can convert carbon dioxide, an environmental pollutant and greenhouse gas, to methanol for use as chemical feedstock and ...

Building crystalline materials from nanoparticles and DNA

Nature is a master builder. Using a bottom-up approach, nature takes tiny atoms and, through chemical bonding, makes crystalline materials, like diamonds, silicon and even table salt. In all of them, the properties of the ...

3-D nanostructure of a bone made visible

Bones are made up of tiny fibres that are roughly a thousand times finer than a human hair. One major feature of these so-called collagen fibrils is that they are ordered and aligned differently depending on the part of the ...

Key to tissue growth may be in anti-wrinkle cream

The first study to investigate the chemical structure of an advanced class of anti-wrinkle cream has shown that it could be used to promote wound healing and regenerative medicine.

3D printing on the micrometer scale

At the Photonics West, the leading international fair for photonics taking place in San Francisco this week, Nanoscribe GmbH, a spin-off of Karlsruhe Institute of Technology (KIT), presents the world's fastest 3D printer ...
