Two-photon polymerization of PEGda hydrogel microstructure

The fabrication of shape-memory hydrogel scaffolds not only requires biocompatibility, micrometer resolution, high mechanical strength, but also requires a low polymerisation threshold in high-water content environment to ...

Semi-random scattering of light

What is the exact path of light inside a highly scattering material like white paint? This is a question that is impossible to answer, as the particles inside the paint are distributed randomly. This, at the same time, is ...

Team designs carbon nanostructure stronger than diamonds

Researchers at the University of California, Irvine and other institutions have architecturally designed plate-nanolattices—nanometer-sized carbon structures—that are stronger than diamonds as a ratio of strength to density.

New record: 3-D-printed optical-electronic integration

Optoelectronic integration offers a promising strategy to simultaneously obtain the merits of electrons and photons when they serve as information carriers, including high-density communication and high-speed information ...

Invisible, stretchable circuits to shape next-gen tech

Electrically conductive films that are optically transparent have a central role in a wide range of electronics applications, from touch screens and video displays to photovoltaics. These conductors function as invisible ...

Erasable ink for 3-D printing

3-D printing by direct laser writing produces micrometer-sized structures with precisely defined properties. Researchers of Karlsruhe Institute of Technology (KIT) have now developed a method to erase the ink used for 3-D ...

Elastic invisibility cloak hides materials from touch sense

In the past years, invisibility cloaks were developed for various senses. Objects can be hidden from light, heat or sound. However, hiding of an object from being touched still remained to be accomplished. KIT scientists ...
