  • MeerKAT released its first image

    Naledi Pandor, S.A. Minister of Science and Technology, is rightfully giddy – she looks to be a woman of great future vision. She gets how all this coalesces for the good of humanity.

    Australia will be home to the ‘second cluster’, funding pending.

    If as the PR blurb says, that dementia will soon be preventable, where on earth will we be able to get contributors for this website?

    I don’t know about occasional visitors to this site, but think of the impact on the Vatican!!!

  • For those wanting replacement joints, this has to be a great discovery!

    Lab discovers titanium-gold alloy that is four times harder than most steels

    Lab discovers titanium-gold alloy that is four times harder than most steels.

    Morosan, a physicist who specializes in the design and synthesis of compounds with exotic electronic and magnetic properties, said the new study is “a first for me in a number of ways. This compound is not difficult to make, and it’s not a new material.”

    In fact, the atomic structure of the material—its atoms are tightly packed in a “cubic” crystalline structure that’s often associated with hardness—was previously known. It’s not even clear that Morosan and former graduate student Eteri Svanidze, the study’s lead co-author, were the first to make a pure sample of the ultrahard “beta” form of the compound. But due to a couple of lucky breaks, they and their co-authors are the first to document the material’s remarkable properties.

    “This began from my core research,” said Morosan, professor of physics and astronomy, of chemistry and of materials science and nanoengineering at Rice. “We published a study not long ago on titanium-gold, a 1-to-1 ratio compound that was a magnetic material made from nonmagnetic elements. One of the things that we do when we make a new compound is try to grind it into powder for X-ray purposes. This helps with identifying the composition, the purity, the crystal structure and other structural properties.

    “When we tried to grind up titanium-gold, we couldn’t,” she recalled. “I even bought a diamond (coated) mortar and pestle, and we still couldn’t grind it up.”
