Japan, One Year After: The Legacy Of A Historic Earthquake

Another promising strategy is the development of the self-powered micro-missiles with enzymes as catalysts. These consist of rolled titanium-gold layer and the enzyme catalase, which is common in animal cells and hydrogen peroxide decomposes into oxygen and water very effectively. Thus the driving force is increased significantly so that will be ten times higher speeds than previously achieved. In addition, micro-drives of this type are better suited for use in biological systems.


The micro-and nanotubes are produced by the technology of the bracing-driven rolling up of thin layers of titanium, iron and platinum. Thin layers are deposited on surfaces that the layers are under extremely high mechanical tension. During detachment of the layers a portion of the strain energy is released, so that the layer rolls up or deformed. In this way, nano-and micro-tubes with great precision in certain diameters and different materials are made from very reproducible.




Using a baking soda type substance, the digestion of wastewater microbes can produce energy as electricity announce researchers.


Generate electricity with wastewater


The reprocessing of waste water is a costly and energy intensive. The process of activated sludge that uses microorganisms to purify the waters of their organic matter requires eg 1.2 KW / h per kg of organic matter. In the journal Science, a team from the University of Pennsylvania presents a new method of water treatment that could one day provide energy rather than consume, thus facilitating water treatment in poor energy.
