Many shades of white

LEDs might revolutionise the lighting industry, but lighting designers will have to get used to working with a light source that is fundamentally different from incandescent bulbs. Industry standards are in place for manufacturing and testing solid-state lighting and are constantly being revised, but work still needs to be done.


Branding the beam

They say location is everything – and since its formation in 1989 the development of Duma Optronics has been influenced and guided by its proximity to Technion, the Israel Institute of Technology in Haifa.


Organic light for organic production

Researchers at TU Dresden and Fraunhofer COMEDD have developed a bioreactor to cultivate micro-algae using organic light-emitting diodes (OLEDs) as a light source. The reactors, roughly the size of a cigarette packet, could help find algal strains that excel in producing substances like proteins, dyes, cosmetics, biofuels and pharmaceuticals.

The project was funded by the Saxon State Ministry for Higher Education, Research and the Arts, and the prototype bioreactor will be shown for the first time at the International Display Workshop in Japan, from 4 to 6 December.


Power of the pulse

While research into attosecond science remains highly specialised and limited to a relatively small number of laboratories, there is a growing amount of work underway on the subject. DARPA, the US defence research agency, launched an attosecond laser project in August and one of the planned laser facilities of the European Extreme Light Infrastructure (ELI) will be dedicated to attosecond science, once it is operational in 2015.


Sound medical judgement

Photoacoustic imaging has proven advantages over conventional imaging methods, but has not yet received clinical approval. According to Professor Jürgen Popp, speaking at the European Photonics Industry Consortium (EPIC) Biophotonics workshop in The Netherlands in November, if a biophotonic technology is to be useful not just in research but also in a clinical setting, then involvement within the scientific, medical and optics industries is fundamental.
