20th anniversary of Freiburg Materials Research Centre

The Freiburg Materials Research Centre (FMF), which is part of the University of Freiburg, recently celebrated its 20th anniversary in the Freiburg Concert Hall. As a central institution of the University of Freiburg, the FMF has been focusing on interdisciplinary basic research and contract research in the field of new materials and materials-related technologies since 1990.

Making visible what the human eye can't see - hyperspectral imaging

Imagine a pen-sized device to check your skin for melanoma. You skim the surface of your skin, and, if necessary, the pen advises you to see your physician to have a closer look at a certain spot. Such a pen would scan your skin, and detect if skin cancer is developing, even in an early stage. It would distinguish between healthy and suspicious spots, even if you can see no difference.

Imec demonstrates integrated electrical sources of surface plasmons

Imec has fabricated electrical sources of surface plasmons, based on integrating light emitting diodes with metal-insulator-metal (MIM) waveguides. These sources, together with earlier work demonstrating plasmon detectors, are a prerequisite for making an interface between electronics and plasmonic circuits. This will lead the way to fully integrated plasmonic biosensing.

Imec and partners study promising application of GeSn for future pMOS devices

GeSn materials show promise, for example as embedded source/drain stressors for Ge channels in future pMOS devices. Imec has started a collaboration to assess the possible applications of GeSn materials, and to see how these applications could be implemented. First results show, among others, that GeSn (with 2-8% Sn) materials are compatible with conventional source/drain engineering processes.

Optical ethanol vapor sensor shows potential of SOI-based integrated gas sensors

An ethanol vapor sensor is fabricated using a ZnO nanoparticle film as a coating on a silicon-on-insulator (SOI) microring resonator of 5 micrometer in radius. The sensor can detect ethanol vapor concentrations as low as 100ppm. This achievement successfully demonstrates the potential of SOI technology for the development of sensitive, compact, low-power and inexpensive optical gas sensing devices.

Communication through chemistry: 'Fuses' convey information for hours

We currently transmit information electronically; in the future we will most likely use photons. However, these are not the only alternatives. Information can also be transmitted by means of chemical reactions. George M. Whitesides and his colleagues at Harvard University have now developed a concept that allows transmission of alphanumeric information in the form of light pulses with no electricity: the 'infofuse'.

Using carbon nanotubes in lithium batteries can dramatically improve energy capacity

Batteries might gain a boost in power capacity as a result of a new finding from researchers at MIT. They found that using carbon nanotubes for one of the battery's electrodes produced a significant increase - up to tenfold - in the amount of power it could deliver from a given weight of material, compared to a conventional lithium-ion battery.
