- JacNet, on 10/12/2007, -2/+11Now it'll be harder to get the buggers off the fridge.
- wvannus, on 10/12/2007, -1/+11You know what? Sure.
- Norweed, on 10/12/2007, -0/+7No, because they're hydrogen bonds not actual bonds...you're not splitting elements here. and even if you were that's not an H-Bomb. An H-Bomb is when you push 2 hydrogen atoms TOGETHER and make He.
- Y0tsuya, on 10/12/2007, -0/+4Depends on where in space you are talking about. It's "warmer" inside solar systems.
http://www.faqs.org/faqs/astronomy/faq/part4/section-14.html - mousy, on 10/12/2007, -1/+5Hydrogen "Bonds" are intermolecular forces, caused by a difference in electronegativity.
- mwmccullough, on 10/12/2007, -0/+4Where did all the real Diggers go? If some of you fools are gonna goof off, I'm sure there are plenty of "Wii" diggs to play with. Magnets and electricity are what brought us to this moment in time technologically. Just because these are of no use on your refrigerator doesn't mean that they are of no use to science. Their applications will be found and probably make some sort of impact on your miserable daily lives, whether you'll be aware of it or not. Now why don't you children head back off to the merry-go-round, 'cause I think that the nanny is gonna call for nap time soon, babies.
- curios, on 10/12/2007, -0/+3It is news worthy, it's under the science section. If this is not science news, then what is?
- ThePict, on 10/12/2007, -1/+4Bond. Hydrogen Bond.
Sorry. Couldn't resist. - Norweed, on 10/12/2007, -4/+7"there is no overall magnetism at room temperature; however, as the temperature is lowered, copper magnetic moments begin to align, producing a microscopic magnetic field visible to the implanted muons below a temperature of 1.54 Kelvin. "
Sweet. So in space I might just be able to have a REALLY weak magnet. What a breakthrough ;-) - thall, on 10/12/2007, -1/+4Is it just me or did that article seem poorly edited?
"...the new compound contains the bifluoride ion in which a hydrogen atom is tightly bound to two fluorine atoms ... however, as the temperature is lowered, copper magnetic moments begin to align..."
Where's the connection between bifluoride and copper? Or was the copper part just way off topic, only there to describe how muons can be really sensitive magnetic sensors (able to pick up the weak magnetic field when copper's temperature lowered)? - tivo, on 10/12/2007, -0/+2magnets are the key toward levitation; stronger magnets will help us get our hover boards sooner.
- inactive, on 10/12/2007, -2/+4wrong bro. it's measured in kelvins, and it's about 2.3~3 kelvins.
The current temperature is about 3 K, or -270 degrees Celsius.

http://en.wikipedia.org/wiki/Vacuum - subxero37, on 10/12/2007, -0/+2Considering hydrogen's electron rotates a single direction, multiple hydrogen atoms seem to make sense for building a magnet, regardless of the field size or the power. Sometimes low-power is what you need (Core 2 anybody?) I like the idea, because even little stories like this that "seem useless" to some people show me that science is progressing ever faster, attempting to decode the mysteries of subatomic particles just as well as deciphering the mysteries of the universe as a whole. If it weren't for simple little discoveries like this, technology wouldn't be where it is today.
Speaking of technology, could this be used in hard drives? Hydrogen is, after all, the smallest element... - curios, on 10/12/2007, -0/+2Hydrogen is a lot more sophisticated than it first seems. The Proton inside could be spin up or down, and the electron likewise giving four possabilities, the electron could be replaced with a muon, yielding 8 possabilities, it could also be replaced with their antiparticle equivalents yielding 16 variations, then you could have an isotope with an extra neutron, giving 32, and also with two neutrons, yielding 64 variations at least.

A vacuum has no temperature. However, when shielded from all external radiation/heat sources an object will thermally sync with the background radiation of the universe. - lhnz, on 10/12/2007, -2/+3bond != bomb
- epimer, on 10/12/2007, -0/+1The bifluoride ions are bridging "ligands" between copper atoms in the structure of the magnet. I agree that that's really not clear from the linked article - I had to go read the paper to see that.
The actual paper is available (as a pdf) here: http://www.rsc.org/delivery/_ArticleLinking/DisplayArticleForFree.cfm?doi=b608791d&JournalCode=CC - inactive, on 10/12/2007, -1/+2@Soapdish
The copper in motors do not exhibit, nor are affected by, magnetic fields. Instead they are wires wrapped around a ferrite core in which they induce an ELECTROmagnetic field. The iron chunk itself exhibits the field, the copper wire is simply a conduit for the electron flow which induces it. - khag7, on 10/12/2007, -1/+1its not intended for commercial use. its intended to create magnetic fields in laboratories for scientific experiments
- darksofa, on 10/12/2007, -1/+1Not too much of a break through, really. When they come out with monopole magnets, then I'll be stoked!
- HyperbolePolice, on 10/12/2007, -0/+0There are about 10 diggers that know what the hell this article is talking about (I'm not one), and yet it somehow makes it to the front page. Ponderous man..
- curios, on 10/12/2007, -1/+1Then imagine a H2 molecule where one atom is different than the other, there would be 128 variations, each with there own unique and subtle different properties
- ThePict, on 10/12/2007, -3/+2Calm down. Geez. Nothing wrong with having a little innocent fun.
The fact that they're commenting in this thread at all is a good thing. Lately, there have been few Diggs or comments in science related articles, and I, for one . . . I mean, I rather enjoy the relative peace.
I consider myself a "real" Digger in that I'm interested in the tech and science articles, but everybody needs to have a little fun once in awhile. It's what makes us human. - Slimer, on 10/12/2007, -3/+2yyyeah, this isn't diggworthy.
i.e. yes, it's a stable fairly large molecule capable of maintaining a magnetic spin. it's not really probing any new physics or breaking any ground. I doubt they're going to learn all too much about the interactions between Fl and Hydrogen, and if they wil, they have their work cut out for them.
Also the article is horribly worded, BUT the colorful picture might spread joy and happiness. - subxero37, on 10/12/2007, -2/+0You are wise. My understanding of subatomic particles isn't that in-depth, I apologize for my naïve approach to my previous post.
- inactive, on 10/12/2007, -3/+2When it's cooled below the temperature of the vacuum of space isn't quite ready for mass-market, but could have massive implications on space travel and gravity detectors.
- inactive, on 10/12/2007, -5/+3even space is a higher temperature than that.
http://www.faqs.org/faqs/astronomy/faq/part4/section-14.html - PDelahanty, on 10/12/2007, -9/+6yes.
- Soapdish, on 10/12/2007, -5/+0One word:
MOTORS! - venvision.org, on 10/12/2007, -6/+1This is lame, so you can make a new magnet, but It has to be below earth temperature to work? Burried
- shawnbttu, on 10/12/2007, -6/+1cool
- inactive, on 10/12/2007, -7/+2Technically the vacuum of space has no temperature. No vacuum does. The reason things freeze is because there's literally /nothing/ there. So all your heat radiates outward into the void as opposed to being insulated by the atmosphere, blankets, etc.
- inactive, on 10/12/2007, -8/+1I call *****. Copper is neither endomagnetic or exomagnetic. Yes, I made those up, but basically I mean it can neither possess its own magnetic field now be affected by an outside magnetic field.
Iron, nickel, and cobalt, people. Iron, nickel, and cobalt. - inactive, on 10/12/2007, -10/+2um i mite be wrong but if u pulled it apart.. wouldn't that be the equivalent of an H bomb.. on your fridge?
- degree, on 10/12/2007, -11/+3no.
