Nature provides the blueprint for tiny robots capable of working inside the human body

A professor for theoretical physics at the Technical University of Berlin is engaged with one of nature's domains, which other people might dread: Gut bacteria and salmonella. He analyzes the movement of those microscopically small organisms in aqueous environments. Following their example, tiny machines with the aptitude to work inside the humanbody could be built.

Tiny silver nanoparticles boost the efficiency of thin-film solar cells

Researchers from the Institute of High Performance Computing of A*STAR, Singapore, in collaboration with co-workers from CSIRO Materials Science and Engineering, Australia, have now revealed how metallic nanostructures can enhance light absorption - even in very thin silicon films - and thus increase the performance of thin-film solar cells.

Molecular worm algorithm navigates inside chemical labyrinth

With the passage of a molecule through the labyrinth of a chemical system being so critical to catalysis and other important chemical processes, computer simulations are frequently used to model potential molecule/labyrinth interactions. In the past, such simulations have been expensive and time-consuming to carry out, but now researchers have developed a new algorithm that should make future simulations easier and faster to compute, and yield much more accurate results.

Sniffing out terrorists

A new intelligent system has been developed to help identify terrorists carrying explosives. Sensitive electronic noses capture the smell of the explosives; the system processes the acquired data, correlates it with individuals' movements - and ultimately tracks down the suspects.

Minor faults in catalyst impose an obstacle to the chemical industry

One of the most important catalysts in the modern chemical industry is a troublemaker. The building blocks of zeolite ZSM-5 crystals, which are a sort of Swiss cheese with molecular size holes, are not joined together perfectly. The materials that have to pass through the crystals therefore often get stuck and don't react well. A researcher has discovered the deviations in the miniscule but indispensable particles.
