Predicting material fatigue: Polymer composites: luminescent zinc oxide tetrapod filler makes inner damage visible

Predicting material fatigue: Polymer composites: luminescent zinc oxide tetrapod filler makes inner damage visible - Detection of material failure is a difficult task for engineers, because cracks inside a material block can hardly be identified from the outside. However, early detection can prevent fatal disasters such as the world's deadliest high-speed train accident in 1998 near Eschede, Germany, caused by failure of a metal wheel. It is even more difficult to detect material failure in composite materials. A research team has now developed a new concept to design so-called self-reporting composite materials.(10.1002/adma.201203849)

Watching single nanoparticles at work - By shining laser light on the modified tip of an atomic force microscope (AFM), researchers in Germany and the Netherlands have been able to watch a catalytic reaction in real time, zoomed right in to the nanoscale. The technique combines AFM with Raman spectroscopy, using the silver-coated AFM tip to boost the reaction’s Raman signal while also acting as the catalyst. Using this hybrid approach, the researchers could follow the catalytic conversion of reactants into products with a spatial resolution of just a few nanometres.(10.1038/NNANO.2012.131)
