Nano-structuring steel surfaces holographically is one of the most forgery-proof ways in the world to ensure that a product is not falsified once it leaves the production plants. And while hologram markers are already placed on a large array of products, from music CDs to cell phone batteries, none of the existing te... |

An international team of scientists from Denmark and Tennessee, the US, have come up with an experimental new way of detecting explosives and other similar, dangerous compounds, by simply going after the smell their physical vapors give out. The new technique is currently being refined and tested in the field, and de... |

Similar to most of the chemical explosives available today, dynamite is a mix of compounds that burns rapidly when ignited. It is based on a chemical substance known as nitroglycerin, a powerful liquid explosive, extremely unstable to physical shock. To harness the potential of nitroglycerin without the downside of i... |

Believe it or not, hand grenades have been invented more than 1.000 years ago by the Chinese people as an application for gunpowder. Europeans on the other hand have been somehow lazier and developed hand grenades for warfare purposes as late as the 16th century, when gunpowder started becoming popular in military op... |

Most substances used in suicidal terrorist attacks are usually home made, that's why it is necessary that security enforcement benefit from the help of a small sensor to detect traces left behind by these chemicals. One of the commonest home made explosives is hydrogen peroxide. Researchers from the University o... |

The manufacturers of the new ThruVision camera say that the device is not able to reveal physical body details of the scanned subject, but if I were you, I wouldn't believe anything the manufacturers say. They could have just as well said that the ThruVision camera can cure AIDS, but until the ultimate test, we ... |

If it's light manipulation, then we're talking about metamaterials. Researchers report to have improved the design of T-ray sensors with the help of a metamaterial that guides T-ray light across the surface of the detector. T-ray sensors are thought to become the next generation of explosive and poison dete... |

X-ray imaging has been serving our medical and industrial needs for more than a century, but it has a series of disadvantages that makes its use rather obsolete. For example, it can only produce a 2D image of the probed sample, cannot diagnose certain diseases, such as breast cancer or Alzheimer, nor metal fatigue as... |

Fireworks make up a beautiful display of sound and color and are the main attraction in many social events, like festivals, inaugurations, concerts, but most of all, on the New Year's Eve. They may be beautiful on the outside, but they have some pretty weird stuff on the inside.The earliest recorded fireworks da... |

A new and improved material can produce sensors used in explosives detection. The fluorescent sensor could find practical applications in new devices built for rapid detection of explosives in security screening, criminal investigations, and other applications. Southern Illinois University's Ling Zang and colle... |

I'm not talking about a terrorist training camp, in which terrorists are trained to launch attacks, ranging from suicide bombing technology training to field combat. It's completely legal and not even expensive, if you want to have lots of fun while training to become an explosives expert. It even beats ex... |
