Peering into the inner workings of catalyst nanoparticles

Scientists can now peer into the inner workings of catalyst nanoparticles 3,000 times smaller than a human hair within nanoseconds. The findings point the way toward future work that could greatly improve catalyst efficiency in a variety of processes that are crucial to the world's energy security, such as petroleum catalysis and catalyst-based nanomaterial growth for next-generation rechargeable batteries

Towards nanowire solar cells with a 65-percent efficiency

TU/e researchers want to develop solar cells with an efficiency of over 65 percent by means of nanotechnology. In Southern Europe and North Africa these new solar cells can generate a substantial portion of the European demand for electricity. The Dutch government reserves EUR 1.2 million for the research.

New type of quantum computer could bring the technology closer to reality

Molecules in quantum states are very fragile. Scientists have devised a way to separate the molecules into their component parts so that the processor's results can be read from the more easily controllable individual atoms. By using lasers, they were able to break down the molecules without compromising the data encoded in them.

World's smallest chess set and a microbarbershop win big

The world's smallest chess board - about the diameter of four human hairs - and a pea-sized microbarbershop were winners in this year's design contest for, respectively, novel and educational microelectromechanical systems (MEMS), held at Sandia National Laboratories in mid May.

Organic nanoelectronics a step closer

Although they could revolutionize a wide range of high-tech products such as computer displays or solar cells, organic materials do not have the same ordered chemical composition as inorganic materials, preventing scientists from using them to their full potential. But newly published research shows how to solve this decades-old conundrum.
