With the Power of SCIENCE

Post by Il Direttore on Sat 11 Aug 2012 - 17:13

So we all know that Gunslinger Girl is intended to be a sort of "20 minutes in the future..." Sci-fi series. However, given the kind of crazy levels of scientific advancement seen in GSG, it seems to me that there are various technologies that, as of this moment, are either in existence commercially, in development for commercial application, or are being researched in colleges/commercial labs, all of which would presumably be feasible under the scientific community seen in GSG. With that in mind, I've decided to start a thread where we can compare notes on scientific stuff we see in and around the internet. My posting the thread here, specifically, is because I hope that the stuff discussed could bring about ideas usable in fanfics for the Forum. The CTMs, for example, could be the basis of Marisa's (Voodoo's OC cyborg) internal heaters. The overall idea is that increased plausibility via grounding in real life always adds to a story.

For example, from the Georgia Institute of Technology's Professor Angus P. Wilkinson, we have (cp-ed from his research profile):

Negative Thermal Expansion (NTE) Materials.
Most materials expand as they are heated, but there is a small and growing group of compounds that shrink on heating (display negative thermal expansion). Such materials are of potential use in composites as blending both negative and positive thermal expansion compounds provides a way of tailoring the thermal expansion characteristics of the resulting material. Being able to tailor the thermal expansion characteristics is useful as there are many applications where either zero thermal expansion is desirable (e.g. optical devices where accurate positioning is crucial) or there is a need to match the thermal expansion coefficients of two parts that are bonded together. We have developed a synthetic method for the preparation of a new NTE material cubic ZrMo2O8and we are currently investigating both the details of its physical properties and methods for tailoring the thermal expansion characteristics of this material and some of its relatives.

Clathrate Thermoelectric Materials.
Thermoelectric devices can be used to provide electrical power from a temperature difference or to produce a temperature difference when supplied with electrical power. There is considerable interest in developing new materials that would facilitate the replacement of current refrigeration technology with efficient all solid-state thermoelectric devices. One attractive candidate family of materials are the so called clathrates. They have 3-D covalently bonded frameworks of atoms such as Si, Ge, or Sn with species such as Cs, Rb, K, Na, Sr, or Eu vibrating inside cavities in the framework. The disorder associated with the vibrational motion of the species in the cavities and any disorder in the framework that is introduced by doping has a large impact on their thermoelectric properties. We are currently exploring the occurrence and importance of disorder in clathrate thermoelectric materials in collaboration with researchers at Renslaer Polytechnic Institute and Marlow Industries.

New Applications of Synchrotron X-ray Methods.
We are interested in further developing the use of synchrotron X-ray diffraction methods for the characterization of materials. The extremely high intensity and high-energy X-ray beams that are available from third generation synchrotron sources provide unique opportunities for examining materials. We are currently working with faculty from the materials science and civil engineering programs at Georgia Tech to develop methods for the non-destructive evaluation of corrosion in concrete and related systems.


"We choose to go to the moon. We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too."
