For the first time ever, a study of this new mathematical model has managed to describe the fracture process for materials such as glass, polymers, concrete, ceramics, metals, rocks, and even certain geological fractures.
New research from mechanical engineers at MIT has revealed a new approach that, by creating specific kinds of tiny structures on a material's surface, can make a droplet spread only in a single direction.
By combining a new generation of piezoelectric nanogenerators with two types of nanowire sensors, researchers have created what are believed to be the first self-powered nanometer-scale sensing devices that draw power from the conversion of mechanical energy.
In the Max Planck Institute for NanoBiophotonics in Goettingen, Stefan Hell has developed fluorescence microscopy methods for observing objects on the nanoscale and with his colleagues Vladimir Belov and Christian Eggeling a new series of photostable dyes that can be used as fluorescent markers has been realised.
Scientists presented a design strategy to produce the long-sought artificial leaf, which could harness Mother Nature's ability to produce energy from sunlight and water in the process called photosynthesis.
