Why Nanomaterials?

Nanomaterials have gained a tremendous amount of traction in the last two decades because of the widely differing properties that are obtainable compared to their bulk counterparts. With their exciting new properties nanomaterials are, ultimately, becoming door openers – enabling both new technologies and revolutionary improvements to current technologies.  Depending on the application, the particle size, distribution, morphology, and purity can have a significant influence on the physical, thermal, structural, and/or optical properties of the end product.  The photograph below illustrates the variation in optical properties for various silica nanoparticle dispersions.  The solutions range from completely clear to totally opaque just by varying the average particle size from 20nm to 200nm.

GE&R Nanomaterials

GE&R silica nanoparticles dispersed in ethanol.

Concentration of silica is the same in each sample.

    It turns out, engineering materials at this small scale is not easy.  As one can imagine, tiny variations in processing parameters, incoming material variations, etc., which would typically be considered negligible for manufacturing bulk scale materials, when manufacturing nanomaterials, can have enormous effects on the resulting structure (size, morphology, etc.), and consequently alter the physical properties that are desired.  Manufacturing nanomaterials with consistent particle sizes, morphologies, and purities, in large scale quantities requires significantly more engineering controls, high end characterization equipment, and procedures in place to ensure quality standards are met – thus achieving tight quality control can be difficult and expensive.  In order for these new technological “doors” to open, the price of high quality nanomaterials needs come down. GE&R has undertaken a significant development effort to create state-of-the-art processes that produce large quantities of high quality, high purity nanomaterials, at economical prices.
