Silver nanocubes make super light absorbers

Microscopic metallic cubes could unleash the enormous potential of metamaterials to absorb light, leading to more efficient and cost-effective large-area absorbers for sensors or solar cells, Duke University researchers have found.

Nature Materials Study: Boosting Heat Transfer With Nanoglue: Interdisciplinary Study From Rensselaer Polytechnic Institute Demonstrates New Method for Significantly Increasing Heat Transfer Rate Across Two Different Materials

A team of interdisciplinary researchers at Rensselaer Polytechnic Institute has developed a new method for significantly increasing the heat transfer rate across two different materials. Results of the team's study, published in the journal Nature Materials, could enable new advances in cooling computer chips and lighting-emitting diode (LED) devices, collecting solar power, harvesting waste heat, and other applications.

Drag-and-Drop DNA: Novel technique aiding development of new cancer drugs

Using a simple "drag-and-drop" computer interface and DNA self-assembly techniques, researchers have developed a new approach for drug development that could drastically reduce the time required to create and test medications.

PTB measurements for the next computer chip generation: Cooperation between Carl Zeiss and PTB on EUV lithography extended

European companies are the world leaders in the development of EUV lithography for the manufacture of semiconductor chips with even shorter wavelengths than up to now, i.e. with 13.5 nanometres in the spectral range of the so-called "Extreme UV (EUV)". The volume production of lens systems and wafer scanners of EU lithography (EUVL) is planned for 2014. In this development, the Physikalisch-Technische Bundesanstalt (PTB) is at the fore. With a new EUV beamline at PTB's own electron storage ring - the Metrology Light Source (MLS) in Berlin-Adlershof - it will characterize EUVL lens systems for this purpose. The cooperation with Carl Zeiss SMT GmbH, which has been running since 1998, has now been extended for another four years. PTB measurements will help to give proof of the quality of the Zeiss lens systems in the so-called "steppers" (lithography machines) of the Dutch company ASML, the global market leader in this field.
