Transparent Aluminum Is Here 625

Alien54 writes "Scientists in the US have developed a novel technique to make bulk quantities of glass from alumina for the first time. (link includes a picture of samples) Anatoly Rosenflanz and colleagues at 3M in Minnesota used a "flame-spray" technique to alloy alumina (aluminium oxide) with rare-earth metal oxides to produce strong glass with good optical properties. The method avoids many of the problems encountered in conventional glass forming and could, say the team, be extended to other oxides (see also: A Rosenflanz et al. 2004 Nature 430 761). Scotty would be pleased."

    who doesn't know the difference between Alumina [wikipedia.org] and Aluminum [wikipedia.org].

    What next, suggesting people use the silicon [wikipedia.org] in their computers as a breast implant [wikipedia.org]?

    With that technology, we can create Alumina Bullet Proof Glass... That's great.

    How about building with alumina windows ? Beter Resistance to fire and EarthQuake ?

    It's a good discovery. Realy.

    Isn't Aluminum a major constituant part of Alumina? (along with Oxygen)... Seams to me that that makes the term 'Transparant Aluminum' valid.

    Where are all the crazy modders?

    - Transparent aluminum case
    - Transparent hard drives
    - Transparent power supplies
    All without voiding your warranty ;-)

    And for military uses - the sky is the limit (really - think about it...)

    You are falling for the assumption that transarent alumina compounds are, in fact, transparent aluminum metal. Lots of gemstones are transparent alumina compounds, too. Rubies, emeralds, etc. They do not bend.

    I am not a chemist, but I believe the condition of the material to allow shifting of bonds that allows metals to bend without breaking is nearly the opposite of the condition present in glass. Ie, alumina glass may be stronger, but it will not bend.

    I once knew a guy who had this great idea to use aluminum oxide on DVDs and CDs to prevent scratching. He said the disks could be bulletproof, scratchproof, and unbreakable, although I think he was exagerating...

    If that was the case, that would be an AWESOME application for this. Although the MP/RIAA would see that as a reason for preventing backup copies of your media. I mean, if the disk can't be damaged, why would you need a backup? Although you could still lose it or have it stolen...

    ...and if you do say it in english please say moscow "moss co." as opposed to "moss cow"... for me that and the pronounciation of "route" and "leisure" are the most irritating americanisms ("route" is said root as opposed to ra-oot (unless an army is routed... but thats a different word) and "leisure" is leh zhure as opposed to lee zhure... i dont mind american accents but i just want to slap anyone saying any of those 3 words *that* way...

    i guess this is flamebait but... what can i do, im russian and ive lived in london for the last 13 years... shit bothers me

    a term doesn't need to be accurate to come into common use.

    Think of these examples:
    Pensylvania Dutch (not dutch)
    Mountain ash (not an ash)
    mountian lion (not a lion)
    american buffalo (not a buffalo)

    Just because a name is born of ignorance doen't prevent it from becoming the common name for something.

    I could see how the Transparent Aluminum of Star Trek is a mislabeled transparent alumina rather than a physics defying metal.

    He could easily be showing a revolutionary new lattice structure into which aluminium atoms could be arranged
    ... or he could just be pulling stuff out of his butt. It's not like the technical consultants who work for the Star Trek shows and movies are known for taking great care to make sure that the stuff in the show fits in, even to the smallest degree, with the science that we know today :)

    Great, all we needed was yet another common source of aluminium. Although the Aluminum-Alzheimer link has not been scientifically established, so can be said about cigarettes and cancer, if you ask the tobacco companies..

    Remote sensing technologies, used to indicate the presence of living bodies onboard an approaching spaceship, as well as the composition of their alien atmosphere. What do we have? X-rays and spectroscopy, both dependent on electromagnetic radiation and a clear line of vision, and we still wrap christmas presents in paper for a surprise effect... Give the kid a tricorder, and there will be no point in wrapping any more gifts for him!

    Also, I love the work they have done on galactic standardization, allowing instant video and audio communication between species that have hardly ever met before. What protocol do they use to agree on frame rate, aspect ratio and colour coding? Not to mention their translation and interpretation services. Someone ought to explain their identification of weapons signatures too; do different munitions have some kind of encoding or does the identification rely on their physical properties only?

    Changing the material of the windows is unlikely to help unless you incorporate the material into the design of the building. The windows are likely going to be designed for easy access and replacement, so it's unlikely to add to the structural integrity of the building unless they are actually designed to do so.

    As to fires, the problem is that if alumina is stronger, it'll be harder for the firefighters to break the windows to let smoke out, gain access to portions of the building, or rescue people (I can't imagine watching people clawing at the windows from inside as they slowly burn to death, while you're helpless to stop it--or maybe I can, but just don't want to).

    That's actually why they'd say wessel - they don't distinguish the two sounds, and their "v" sound is between our w and v.

    Ah, no. Their 'V' is just like our 'V', but generally pronounced harshly. 'W' is a very different sound that they lack. They would have said "nuclear vessel", but pronounced "where" as "vhere". The problem during the cold war is that the public heard very little Russian spoken. Thus it somehow entered into common usage that the V's and W's get switched with a Russian accent. This simply isn't the case.

    A more likely reason for the confusion is that Russian has several sounds which English does not. (For example, they have a 'zsa' sound as in the name Zsa Zsa Gabor. They transliterate all J's into zsa's.) Since these sounds often serve as replacements for english sounds, many people have difficulty in distinguishing exactly what sounds were used. Thus silliness like W's instead of V's entered as a common idea of a Russian accent. No real Russian sounds like Mr. Chekov (who's name we absolutely murder in pronunciation).

    The article refers to them as alumina glasses, so, uh, "amorphouse". A glass is by definition not a crystal.

    I recall hearing something about IBM making a glass platter hard drive with massive storage capabilities, but due to the nature of glass they abandoned the project, they failed to achieve a product that could survive shipping.

    Could this be the answer to their problem?

    You've completely missed my point.

    "You forget water is more then just hydrogen.."

    That is my point!
    Aluminum-oxide is more than just aluminum.

    Twice now you've referred to this material as a transparent-aluminum.

    My point is that it's not aluminum.
    It is aluminum-oxide (aka, Alumina).
    This isn't about color additives.
    One is a metal, the other is a ceramic!

    Knowing this, go back and re-read my first post and then you'll understand what I said a little better.

"Protozoa are small, and bacteria are small, but viruses are smaller than the both put together."
