Some carbon nanotubes can increase in both length and width
when uniformly compressed. Could this material improve byicycle gears?

Design one material with properties that can be used for packaging all or most products so that most trash can contain one material. By doing so would increase recycling efficiency by eliminating the seperating process of recycling. When the 3-D printer becomes available for the masses it needs to be compatible with this material so that waste can be reduced even further.

Connect the bathroom sink drain to a resevoir that leads to the toilet' s tank, and connect the shower drain to a resevoir that lead to the lawns sprinklers, roof water has potential also. I realize I'm not the first to think of such things but that doesn't matter because I think there are lots of people who are oblivious to them.

Apart from post 3, which is pretty obvious, Izdumb.

Why, is it because their impossible or because you are.

Why, is it because their impossible or because you are.

1) Carbon Nanotubes are tiny. It's that "nano" part.

2) Too many products with different requirements. And 3D printers have their limitations, too. They can't work with any material. It has to be compatible with the process.

3) Is good. Some aspects of it are already in practice.


And that retort was beyond lame.

My friend's apartment in Japan was set up this way.

1)Researchers at Shinshu University in Nagano, Japan, have significantly improved the corrosion properties of magnesium alloys by adding multiwalled carbon nanotubes (MWCNTs) to them.The researchers have found that the corrosion resistance of magnesium alloys can be improved by adding around 5wt% of short, linear, well-ordered MWCNTs.
The mechanical properties improved too, with increases in the elastic modulus and tensile strength of the material, making these materials promising alternatives to aluminium alloys and engineering plastics in many applications. They could replace aluminium alloys and engineering plastics in commercial applications where lightweight, hardness and mechanical strength are required.

2)Researchers at Case Western Reserve University have developed a nanocomposite that changes its stiffness in response to the presence of water. The composite is made of cellulose nanofibers embedded in a rubbery polymer matrix. An ethylene oxide-epichlorohydrin (EO-EPI) copolymer was chosen because of its ability to absorb a little bit of water, and its propensity to form well-defined, percolating nanocomposites with cellulose nanofibers. Cellulose fibers extracted from sea creatures known as tunicates were selected because of their high stiffness and surface chemistry.
The nanofibers are rich in hydroxyl groups. This permits switching by turning
hydrogen bond interactions on and off through the absence or presence of a
competitive hydrogen bonding agent, in this case water. In the absence of water, the material is strong and rigid. When exposed to water, the water interferes with the interfiber interactions and the material becomes about 1000 times.

Most of my waste is paper, plastic, glass, and aluminum, how is this too many.

You said " And 3D printers have their limitations, too. They can't work with any material. It has to be compatible with the process." and your right

I said
"When the 3-D printer becomes available for the masses *****it needs to be compatible with this material***** so that waste can be reduced even further. "

"And that retort was beyond lame" The fact that you use the word lame over shadows its purpose

1) Yes, it is well known that composite materials can have improved performance over single materials given the right composite and the right application. What's your point?
BTW, the supplementary material you added doesn't mention the supposed auxetic behaviour of carbon nanotubes from the OP.

2) Plastic isn't a material, it's a behaviour of materials. Polymers come in many varieties and very few are suitable for co-recycling.


PS. Be careful with acronyms relating to nanotubes.... especially those made of copper

Heh.

I have one made of gold. She seems nice enough.

In both cases, soap and other contaminants may render this undesirable.

Peeing in the sink is good for the lawn.

Nightsoil is good for the crops.
