One of the most severe limitations of chemistry today is the fact that experts cannot, for example, mix two highly reactive compounds together until they are sure they want the reaction to proceed. In other words, they cannot place two such substances in a mix, and then trigger the reaction between them at will. Thro... |

X-rays have been identified as one of the most energetic forms of light in the Universe over the years, and their power has been harnessed to create scanners in airports and radiotherapy. However, it's only now that their true power is starting to be tapped into, researchers announce. Scientists at the Universi... |

Experts from the Rice University, in the US, and the Universite Lyon1/CNRS, in France, have recently released the first videos depicting the atom-by-atom growth of carbon nanotubes. Much to their amazement, they noticed that, as individual atoms were added to the nanoscale constructs, the entire structure rotated, in... |

Detecting bacteria using existing techniques in the laboratory at this point takes at least two days to perform. The samples are first enriched, then separated, identified and counted, and the entire process just takes up a lot of resources and time. With the help of a new biosensor, this type of analysis may soon be... |

Despite having a “unitary” sound to their names, carbon nanotubes (CNT) can actually be of varied compositions and structures, as determined by their electronic properties. However, when they are produced in bulk, many types of CNT are generated in the same space, and disentangling something that is a few... |

A lot of people have thankfully heard of carbon nanotubes in recent years, and most of them know that they are incredibly small constructs, built at the nanoscale, and which are made of single layers of carbon atoms, stuck together in the shape of tubes. But not many people know that these tubes, also known as buckyt... |

Hydrogen is, at this point, the leading source of alternative fuel in the world. Its potential to power up the cars and vehicles of tomorrow is only limited by the fact that there are currently no materials able to hold vast amounts of hydrogen. This is necessary for giving the vehicles a range similar to that they h... |

Producing carbon nanotubes is easy - scientists cracked that secret more than a decade ago, albeit making them grow in an orderly fashion is somewhat more complicated. Or at least it was, because two teams of researchers have recently proven new methods through which carbon nanotubes can be sorted and organized so th... |

Aside from being very unreliable when it comes to retaining an electric charge for long periods of time, typical batteries sometimes also have problems with excessive heating that can make them either explode and start fires, or leak toxic fluids when left unused for long periods of time. Additionally, most of the ti... |
