This press release is available in German. At the Photonics West, the leading international fair for photonics taking place in San Francisco (USA) this week, Nanoscribe GmbH, a spin-off of Karlsruhe ...

The Lawrence Livermore National Laboratory is working on a petawatt-class thulium laser that is said to be 10 times more efficient than the CO2 lasers used in EUV tools and could replace CO2 lasers in ...

Scanning probe microscopy (SPM) is a set of advanced methods for surface analysis. The recent advances in SPM of metals, polymers, insulating, and semiconductive materials are primarily due to the ...

The multistep, two-photon-lithography-based additive manufacturing method forms intermediate products of blank polymer, Ni-infused polymer, and NiO while fabricating Ni nanopillars. (Credit: Zhang et ...

In 1964, just four years after Theodore Maiman's pioneering laser operation at the Hughes Research Laboratory in California, the James Bond film Goldfinger hinted at laser cutting, albeit for less ...

Portland, Ore. – A soft-lithography technique that harnesses deoxyribonucleic acid (DNA) as a self-reproducing template is being developed at the Massachusetts Institute of Technology's Supramolecular ...

Researchers at the Paul Scherrer Institute PSI, in collaboration with the National Institute of Standards and Technology (NIST) in Boulder, Colorado, have for the first time succeeded in using ...
