Polyethylene is the most widely used plastic. It's not clear how practical this research is for industrial-scale use, involving as it does an atomic-force microscope. The work is detailed in a paper published in <a href="http://www.nature.com/nnano/index.html"> <em>Nature Nanotechnology</em></a> this month. <i>"The new process causes the polymer to conduct heat very efficiently in just one direction, unlike metals, which conduct equally well in all directions. ... The key to the transformation was getting all the polymer molecules to line up the same way, rather than forming a chaotic tangled mass, as they normally do. The team did that by slowly drawing a polyethylene fiber out of a solution, using the finely controllable cantilever of an atomic-force microscope, which they also used to measure the properties of the resulting fiber. This fiber was about 300 times more thermally conductive than normal polyethylene along the direction of the individual fibers, says the team&rsquo;s leader..."</i></htmltext>

	<htmltext><p>I'm not too clear on the manufacturing details here. But the material itself sounds a lot like the original Polaroid film (not the photographic kind, the polarizing kind), which is a type of plastic polymer, impregnated with iodine, which has been stretched in one dimension to align the polymer molecules along that dimension. The iodine atoms are able to conduct electrons between themselves, effectively forming "wires" which absorb radiation polarized along the direction of the molecules. I wonder if a block (as opposed to a sheet) of such a material would also conduct heat along one dimension. Things which conduct current also conduct heat well.</p><p>I suppose the devil is in the details, and the real accomplishment here is not the alignment of the molecules, but the ability to do so throughout a <i>block</i> of material instead of just a thin sheet. But what if you just made a bunch of sheets and stacked them up to make a block?</p></htmltext>

	<htmltext>It's not wrong, it's just using a more technical definition of "direction" than the one you're used to. In the mathematics and physics I was taught, a vector has three attributes: a magnitude, which is a positive number; a direction, which is similar to a line, not a ray (eg north-south, not just north; the x axis, not just positive x; etc.); and a third thing which determines which way it's going along that direction (a single bit, basically); I'm not sure what this last thing is called in English, so let's call it sign, since you typically decide which way is positive and which way is negative along a direction, and then a signed number gives you both the magnitude and the sign.<br> <br>
This definition of "direction" may seem counterintuive at first, but it's really quite useful, because in physics you often encounter things which have to do with a direction in this sense (as is the case with this new material). That also explains why the writers of the article used this definition.
<br> <br>
Note that you cannot simply use "dimension" in its stead. There are three dimensions in three-dimensional space (by definition), but infinite directions, so it's clear that they cannot be the same thing.</htmltext>

In the mathematics and physics I was taught , a vector has three attributes : a magnitude , which is a positive number ; a direction , which is similar to a line , not a ray ( eg north-south , not just north ; the x axis , not just positive x ; etc .
) ; and a third thing which determines which way it 's going along that direction ( a single bit , basically ) ; I 'm not sure what this last thing is called in English , so let 's call it sign , since you typically decide which way is positive and which way is negative along a direction , and then a signed number gives you both the magnitude and the sign .
This definition of " direction " may seem counterintuive at first , but it 's really quite useful , because in physics you often encounter things which have to do with a direction in this sense ( as is the case with this new material ) .
That also explains why the writers of the article used this definition .
Note that you can not simply use " dimension " in its stead .
There are three dimensions in three-dimensional space ( by definition ) , but infinite directions , so it 's clear that they can not be the same thing .</tokentext>
<sentencetext>It's not wrong, it's just using a more technical definition of "direction" than the one you're used to.

	<htmltext>This material could be another boom material for the spacecraft industry. Some of the heavier hardware on any given space payload is the thermal control system. Using a combination of <a href="http://en.wikipedia.org/wiki/Heat\_pipes" title="wikipedia.org">heat pipes</a> [wikipedia.org] and surfaces coated in various colors of paint  for heat control can add a significant amount of weight to a spacecraft. If this material can be added as a thermal layer to <a href="http://en.wikipedia.org/wiki/Multi-layer\_insulation" title="wikipedia.org">the MLI</a> [wikipedia.org] layers that are tacked onto the outside of a spacecraft, it may go a long way in reducing and simplifying the thermal control subsystem of the given payload. In fact, since it is a simple plastic, it should be significantly lighter than various metal contacts and conduction paths within a spacecraft that are used today.
<br> <br>
The single dimension (not direction) transfer mechanism could also be very useful. If you can ensure that heat will move along only a single axis, you have a bit more freedom in placing sensitive components in and around your conduction paths within your spacecraft. All in all, this could be a really useful material, if it can ever be scaled up for use in industrial applications. Here's hoping.
