Using a series of complex techniques, investigators at the University of Bristol, in the United Kingdom, announce that they were able to calculate two critically-important properties of graphene for the first time ever. The material may one day replace silicon in electronics.
Graphene is a bi-dimensional carbon com... |

A team of scientists from the US National Institute of Standards and Technology (NIST) say that graphene has the tendency to become more slippery when stacked. In a single-sheet configuration, the material usually slows down objects.
The NIST group compares the effect a single layer of graphene has on objects rolli... |

According to a new scientific study, it would appear that the most basic laws of introductory physics do not hold up to scientific scrutiny, as evidenced by lab bench models of how earthquakes are produced. Investigations such as this have huge potential, in the sense that they could provide new insight for improving... |

A team of astronomers investigating extrasolar planets has recently determined one of the main reasons why these celestial bodies have radii that are a lot larger than they should be. The fact that this class of exoplanets is “puffy” has been known for quite some time, but experts have until now been unab... |

Slips are some of the most well-known types of flops that humans have, especially in the winter time. Those of us who live in the Northern Hemisphere are more than accustomed to wintertime falls, slides, slips and broken bones. One of the main culprits behind the inconveniences caused by these accidents is the reduce... |

A Canadian company may have developed a prototype for a new generation of wind turbines. Rather than relying on complex gearboxes to convert wind energy into electricity, the new design, of which a scale model has already been built, makes use of friction forces to do exactly the same thing. The innovation, if applic... |

According to experts at the Georgia Institute of Technology (Georgia Tech), positioning and manipulating tiny carbon nanotubes is one of the last standing major issues that need tackling in the field of nanotechnology. Integrated nanoelectronic and photonic circuits, nanosensors, interconnects and electro-mechanical ... |

A new scientific study shows that, during heavy storms, the smaller droplets of water falling from the sky are actually traveling faster than others, and also faster than they should be able to. The find, which scientists say is like discovering the meteorological equivalent of breaking the light-speed barrier, could... |

Lightning is an atmospheric phenomenon that even today remains mostly mysterious to the researchers. On top of having enough difficulties explaining why lightning forms in the fist place, scientists have also been struggling for decades to understand why bolts of lightning forming in the top layers of the clouds trav... |

Micro-electro-mechanical systems, popularly referred to as MEMS, in small electronic devices often fail because of adhesion and stiction - the attractive force between the surfaces of interacting parts. University of Arkansas researchers have developed a surface-topography engineering method that reduces these forces... |
