Nanoscale Mold

  • Killing people and blowing stuff up has been losing appeal recently, and I suppose that that would be a sign of a sort of maturity. But other than weapons and means of war, there is still plenty to be contributed to the world, and the topic today is nanoscale materials.

    Arranging all the atoms in a mass of material yields materials with properties nothing short of magical. A thread of light alkali metals linked together in a series of organized ionic bonds held in a precise triangular lattice strung across a road has the potential to cut a car in half. But the potential of such materials aside, how do we efficiently organize atoms on a large enough scale so that we can actually produce enough material to b of use?

    The aforementioned NME (nano material engineered) thread/car cutter would consists of trillions of individual atoms per centimeters of thread, how can we then, rapidly arrange so many atoms? Well, isn't this a question asked by the earliest of industrialists? So much material has to be shaped to make a chunk of iron into a usable knife or pan, having individual blacksmiths pound away at the ingot is definitely not the way to go, instead, we make a mold that produces one shape over and over again.

    When we feel or push something, like my fingers feeling and pushing the keys on my keyboard, the atoms in my finger are not actually touching the atoms in the plastic keyboards. I feel the keys under my fingers when the electron clouds of the two collide, the actual atomic nuclei never comes into contact. Even now, between your buttocks and your seat, there lies a few angstrom units of space dominated by the electron clouds of whatever you are wearing on your butt (I hope you are wearing something there) and whatever the materials of your seat.

    The distance between atoms I mentioned is a nice little nonstick coating of you will, for the mold I now propose. To make the mold we use conventional means to aline a grid of nanoscale electrodes, each with its own electrical field. To shape the mold, we provide ore power to some electrodes while giving less to others, creating an uneven electron surface in order to acquire a desired shape, such as a nanoscale triangular lattice. Once the desired shape is set, the material that needs to be shaped is ground down to a fine nanoscale powder and heavily ionized negatively to maximize the distance between it and the mold, and to also prevent clumping of the substrate material before it takes the shape of the mold.

    A few seconds later after the mold is filled, the substrate material is de-ionized and normal ionic and covalent bonding takes over, "solidifying" the material into its desired shape, and the mold is reset for another shape, another batch of material, and produces another NMEed batch of material.
