Magnets Can Control Heat And Sound? Shocking New Research Suggests They Can
hngn.com ^

Posted on 03/24/2015 9:10:14 PM PDT by BenLurkin

The study is the first ever to prove that acoustic phonons (particles responsible for the transmission of both sound and heat) contain magnetic properties, The Ohio State University reported. The team of researchers demonstrated that a magnetic field about the size of an MRI was able to reduce the amount of heating flowing through a semiconductor by about 12 percent.

"This adds a new dimension to our understanding of acoustic waves," said Joseph Heremans, Ohio Eminent Scholar in Nanotechnology and professor of mechanical engineering at Ohio State. "We've shown that we can steer heat magnetically. With a strong enough magnetic field, we should be able to steer sound waves, too."

Next thing we’ll know is that CO2 causes dangerous global warming.....

“The findings were published in a recent edition of the journal ‘Nature Materials’.”
And they’re just now getting it? Where have they been for the last 200 years? It’s been done. Over and over.

From the article, it appears that this is not scalable considering it would take a “crapload” of power to generate the magnetic field necessary to produce the effect...........I think.

"This discovery will not be applicable in the near future because 7-tesla magnets like the ones used in the study are not available for commercial used and semiconductors must be chilled to nearly absolute zero in order to make the atoms slow down enough to be detectable." So much for that.

So much for that.

It's not how well the bear dances, it's that he dances at all.

In other words, regardless of its current practicality, this is an unexpected effect not previously observed, and it has theoretical implications that may well lead to something very useful down the road.

Does that pertain to the feckless fool on the hill?

Oh! I'm ~Sooo~ surprised!

I have wondered for a couple decades whether sound could be controlled for people living near freeways or airports.

Human activity near magnetic north has reduced the topsoil - and the increased magnetic fields resulting from the thinning protective mantel is causing global warming.

OK - it’s not really CO2 - but it’s still man made, and it’s going to take a whole freaking buttload of money to redistribute, and HUGE changes in lifestyle by everyone but me to fix it!

YAY!

I have to admit, the term “acoustic phonons” is a completely new one on me... I’m familiar with a purely kinetic model of sound as a pressure wave. Dunno ‘bout no “phonons.” Frankly, it sounds phony to me.

Phonons originated in solid state theory some time ago. In a crystalline solid there are a discrete number of vibrational excitations, and each of these can be excited in discrete quanta, representing phonons.

An interesting consequence of this well-verified theory is the zero phonon line - a radioactive decay that does not cause an excitation of a phonon due to the recoil of the nucleus, since in this case the entire crystal aborbs the momentum due to “spooky action at a distance.” It’s a unique phenomenon known as the Mössbauer effect, and it has widespread technological applications.

So, how does that affect carbon dating?

It’s a brave new world. Carbons can date each other if they want to.

Not quite as big as MRI
