Multifunctional nanocomposites based on alignment of graphene nanoplatelets

BACKGROUND Since its isolation in 2004, applications for graphene (atomic-scaled carbon hexagonal lattice) have been highly sought after, particularly due to its lightweight nature, high modulus, strength, and surface area to volume ratio. A promising form is created by employing graphene nanoplatelets in resin and orienting them with an electric field...

Coating, Layer, and Bulk Material for Extreme Thermal Protection

BACKGROUND High-temperature applications, such as rocket engine combustion output, can reach temperatures as high as 3,315 °C (6,000 °F). Enough heat to fuse a concrete surface, like a launch pad, into glass. Fused concrete has a limited lifetime as structural integrity is compromised in some cases immediately, resulting in potentially dangerous...

Adaptive Pore Size Smart Material

BACKGROUND Prosthetic limbs are typically mounted to the remnant limb via a sleeve, which are made from a variety of materials, but mostly from silicone elastomers. Unfortunately, these sleeves heat up the limb remnant and can lose grip as the temperature increases and sweating occurs. This problem is addressed via two approaches: medical treatments...
