Atom Clusters Have Interesting Properties

Posted by michael on from the materials-science-still-a-very-interesting-field-to-enter dept.

An anonymous reader writes "Researchers have found clusters of aluminum atoms that have chemical properties similar to single atoms of of other elements. That, says Science Blog, could open the door to a new periodic table of cluster elements to create compounds with distinctive properties never seen before."

  5. 3 easy steps to prevent dupes by EnronHaliburton2004 · · Score: 5, Insightful

    Dear slashdot editors,

    Here are 3 easy steps on how to prevent duplicate articles. This is why your employeer pays you money.

    1. Use your own search feature to search for the actual hyperlink and/or a few keywords.
    2. Scan the article list over the last few days.

    This will prevent the vast majority of Dupes, and it won't take too much of your time.

    Finally, you should CHECK EMAIL SENT TO DADDYPANTS. Why isn't this done?

    Frequently, email to 'daddypants' bounces back. Other times, the email is ignored and the duplicate article is posted. I rarely see a duplicate article get pulled from the queue.

    If you actually check email sent to daddypants, it might encourage well-meaning /. readers to use that feature more often.

    You have an army of subscribers who are willing to help out AND PAY YOU MONEY TO DO SO.

    With my non-troll account, I am actually a subscriber. I like reading the articles before they get slashdotted, sometimes I'll post the text to a /. post, and if I see a duplicate article I send an email. I want to help, and I long for what /. used to be...

      This is why your employeer pays you money.

      Actually, like any employer, they pay the editors money only because they think that the salary will have a good return on investment, i.e., that the editor's efforts will return more money to the coffers than not paying the editor would have.

      So: they don't want to stop dupes; their bosses insist on the dupes! It's advertising revenue. We can't stop it no matter how loudly we complain.

      Doesn't matter what you call them; and their bosses are directing them to post duplicates because it increases advertising revenue.

      So, no, their bosses could not make more money by hiring better story pickers. (Unless by "better" you meant "willing to post more dupes"...)

  8. Molecules by another name? by TapeCutter · · Score: 1

    The article says nothing about what a "cluster" actually is. With my limited chemistry knowlage it sounds like they are describing a molecule. In the case of Aluminium the "shells" are arranged as 2:8:13 so there are 14 possible molecular forms or "clusters".

    What is the difference? If there is no difference then it is not news that the atomic and molecular forms of elements have different properties. eg: I find it safer to breath my oxygen atoms in bound pairs.

    1. Re:Molecules by another name? by Saikiran · · Score: 1

      It's not really a molecule. Molecules are "bonded" due to Chemistry(covalent bonds, sharing electrons and all that jazz). Clusters on the other hand are formed due to a need to minimise energy.

      To my understanding, it's something like soap molecules in water which most of us would have learnt about at some stage. They have a spherical head part which loves water and a long tail which hates water. So, bunches of molecules form spherical "clusters" where all the tails are on the inside of the sphere, guarded from water by the heads on the outside. Many substances form clusters (usually at low temperatures). Recently, Prof. Eugene Stanley and associates discovered that even Water forms these clusters at sufficiently low temperature.
