Abstract: |
The
project involves the synthesis and evaluation of titanium oxide-based
materials, zeolites and aerogels. Synthesis involves the mixing and
proper chemicals in the proper order, the formation of the appropriate
chemical mixture under appropriate temperature and pressure conditions,
and the removal of the residual solvent. Evaluation includes the measurement
of surface area after various pretreatments, the determination of surface
chemistry via infrared techniques, and the testing of these materials
for various chemical reactions.
At the
end of this summer experience, teachers will be able to bring knowledge
of new materials into classroom curriculum. |

Aerogel Capabilities
Aerogel
is not like conventional foams, but is a special porous material with
extremely microporosity on a micron scale. It is composed of individual
features only a few nanometers in size. These are linked in a highly
porous dendritic-like structure.
This exotic
substance has many unusual properties, such as low thermal conductivity,
refractive index and sound speed - in addition to its exceptional ability
to capture fast moving dust. Aerogel is made by high temperature and
pressure-critical-point drying of a gel composed of colloidal silica
structural units filled with solvents. |
