Young's modulus of selected materialsNanomaterials (2)

Beef or Horn?

As every mechanical engineer knows, the stiffness of a material — its elastic modulus — is often a critical property; likewise in nanomechanical engineering, though in part for a different reason. I’d like to say a few words about this, then discuss some materials of interest in implementing nanosystems. And there is something I must say about beef, too.

Stiffness matters

Stiffness determines how much a component will deform in response to a force, or equivalently, how much elastic energy will be stored in the process of distorting a component into a given shape. In nanomechanical engineering, the energy is of special importance, because the probability of a distortion declines exponentially with increasing elastic energy — in other words, stiffness limits the amplitude of thermal fluctuations. (This post was getting too long, so I moved further discussion of this topic to another page: Elastic Modulii, Stiffness, and Thermal Fluctuations.

The chart below compares the (Young’s) modulus of some very different materials.

Young's modulus of selected materials, including meatToward advanced nanosystems

  • The range of modulus values for structural proteins is like that of engineering polymers: Some are like rubber; many are like epoxy, polystyrene, or polycarbonate; and silks can rival Kevlar.
  • DNA, although valuable as a medium for design and fabrication of large, atomically precise structures, is much softer than structural proteins.
  • In comparison to a typical structural protein, the stiffness of pyrite (FeS2, also known as fool’s gold), rivals that of diamond. A number of metal oxides have elastic moduli that are somewhat greater than pyrite.
  • Finally, except for steel and diamond, all these materials are readily synthesized at low temperatures from substances dissolved in water. The same is true of several metals and semiconductors, and of many silicates and metal oxides.

Sure, many physicists understand QM

by twice_shy_nlli

QM is just the study of the physical properties of extremely small objects is all. Thousands of physicists understand it quite well, and hundreds understand it extremely well. The emerging field of Nanotechnology depends upon a good understand of QM, and the business investors can't wait to invest money into that field. Folks with money to invest are good folks to watch when deciding which fields are well understood and which aren't.
No subject in physics will ever be completely understood of course, for there will always be more to learn about any subject. And the relationship of QM to other fields of study in physics will always result in more work required

What ABOUT nanotechnology? enlighten us!

by Ciph3rzer0

In terms of AI, it is not that we don't have the power to create a AI that is equally intelligent as us. We just HAVEN'T PROGRAMMED IT YET.
It turns out, this intelligence stuff is a lot harder than once though. People were predicting AI would be a 10 year project, and we would have little #5's and r2-d2's zipping around the planet. Many decades have passed and we barely have a foothold on AI. Never mind understanding and cognition, which would be necessary for the computer to "understand us"

Carbon-based nanostructures are already being used as materials in solar cells with increasing frequency, yet their ability to enhance electrical performance has thus far been hampered by limited ability to assemble orderly networks using the materials.
