A long time ago, metallurgists noticed that certain solid metals, which had been engineered for ductility, could suddenly become brittle. The process, designated liquid metal embrittlement (LME), has been under investigation ever since. Now, a team of scientists finally proposes an explanation.
LME oftentimes occu... |

For years, physicists have been observing a peculiar phenomenon in metal surfaces on which light was shone. Mysterious electromagnetic “hotspots” appeared to develop on them, but only at the nanoscale. A team of experts now believes it has discovered the missing piece to this puzzle. The work was conducte... |

As anyone working in shaping materials can tell you, there is a certain limit to the degree of accuracy a press can instill into solids such as metals. From a certain point on, the force the press needs in order to make the modifications starts producing cracks, and perforates the material being shaped, causing imper... |

Since superconducting materials were first discovered, physicists have attempted to instill this amazing property into hydrogen, the most common chemical element in the Universe. Such a breakthrough would pave the way for a massive technological boom, but this has still to be achieved. The obstacle is that turning hy... |

Our planet is known to have a core, but not many people know that this central, molten region is also divided in two parts – the inner and outer cores. In a new scientific study, it was demonstrated that the outer core was indeed influenced by decade-long stirring motions, which kept it churning. This was hypot... |

Optics Professor Chunlei Guo, from the University of Rochester, has made headlines over the last couple of years with some of his innovations, including the laser that is able to change the color of metals when fired upon them. Originally thought to be nothing more than a method of producing aesthetically pleasing me... |

While the global financial crisis wrecks havoc in workplace, forcing employers to fire many people, there are sectors that are still in desperate need of skilled workers. One such sector is that related to the production of polishing injection molds. These structures are extremely difficult to manufacture, and requir... |

According to a team of experts from the University of Warwick, it may be that using the transition metallic elements Ruthenium and Osmium could lead to the creation of new and improved drugs for conditions such as colon and ovarian cancer. The new drugs may be especially effective against cancerous cells that have al... |

The idea that electric “continuous currents” flowed inside small metal rings indefinitely was proposed since the earliest days of quantum physics, in the 1920s and 1930s. At the time, it was stated that the currents were small, but that they flowed through the rings indefinitely, regardless of whether or ... |

Severe disorders such as epilepsy, Parkinson's disease and perhaps even paralysis could be cured with nanoparticle-based treatments in the future. The tiny structures were recently proven to be able to assist human nervous tissue in regrowing, following accidents, and also showed a remarkable ability to carry dr... |

A team of scientists from the US Air Force Office of Scientific Research, led by Dr. Chunlei Guo, recently announced the development of a new method of treating metal, which involves tremendously intense bursts of laser. If a shiny piece of metal is bombarded with the laser pulses, it eventually changes its color to ... |

In a study that would have been considered witchcraft, or alchemy at best, a few centuries ago, researchers at the California Institute of Technology (Caltech) have managed to create metal alloys that do not exhibit the basic property of metals, namely the ability to expand when subjected to heat. In addition, the ne... |

Titanium is best known for being one of the toughest materials out there, but no one could have imagined that it would end up being used to replace glass, in applications that demand strong and transparent materials. The zirconium chemical element will also be used together with titanium, and will eventually replace ... |

The March 12th issue of the journal Nature features one of the most interesting articles to date, in which researchers from Stony Brook University (SBU) and Jilin University (JU) show that the element sodium (chemical symbol Na) can become transparent when subjected to high pressures. This behavior was thought to be ... |

Messier 101, also known as the Pinwheel galaxy, is a spiral galaxy located about 27 million light-years in the constellation Ursa Major, having a diameter about twice that of the Milky Way and containing vast amounts of high-density hydrogen gas, which gives it a fluffy-looking appearance. According to some estimatio... |

A new and interesting method of combating heavy metal pollution presents itself in the form of...air. It is a novel aerogel that is made mostly of thin air, trapped in large spaces between the gel molecules. With an incredibly low density, it can soak up vast amounts of heavy metals in run-off water from polluted in... |
