Stretchable nano-ceramics made by flame technology

Scientists have successfully been able to transfer the experience from furnace to laboratory while synthesizing nanoscale materials using simple and highly efficient flame technology. This 'baking' of nanostructures has already been a great success using zinc oxide. The recent findings concentrate on tin oxide, which opens up a wide field of possible new applications.

New study shows the dynamics of active swarms in alternating fields

Researchers have studied the dynamics of active swarms using computer simulations and experiments on unicellular algae. The team not only found full analogy of the active motion in a field to magnetic hysteresis but also managed to quantify the controllability of the swarm and identify the signatures of collective behavior of the active agents.

A microscopic approach to the magnetic sensitivity of animals

Researchers have succeeded in developing a new microscope capable of observing the magnetic sensitivity of photochemical reactions believed to be responsible for the ability of some animals to navigate in the Earth's magnetic field, on a scale small enough to follow these reactions taking place inside sub-cellular structures.

Engineers show how 'perfect' materials begin to fail at the nanoscale

Crystalline materials have atoms that are neatly lined up in a repeating pattern. When they break, that failure tends to start at a defect, or a place where the pattern is disrupted. But how do defect-free materials break? Until recently, the question was purely theoretical; making a defect-free material was impossible. Now that nanotechnological advances have made such materials a reality, however, researchers have shown how these defects first form on the road to failure.

Cost-effective risk assessment of nanomaterials may be feasible

The Dutch National Institute for Public Health and the Environment has commissioned the development of a strategy to evaluate the potential for read-across in cases of missing data for nanomaterials, with a focus on fulfilling data requirements in regulatory frameworks.
