About Some Mechanical Properties

To judge if a particular kind of material is a good fit for some purposes, the criterion are based on its mechanical properties, which allow us to know how far it could go when it’s in the position.

Hydrophobe and Hydrophile

Hydrophobicity is the property that a molecule repels from the contact with water. You can always see leaves or grass with dews on them – if the leave or grass is hydrophobic, the dew would tend to look like a perfect sphere. And the dew rolls down easily when you gently shake the leave. A hydrophile, on the contrary, likes interacting with water molecules. A water drop on a hydrophilic surface has the contact angle smaller than 90 degrees.

Understanding Graphene/Polyamide Nanocomposites

Hello, I’m Jing Ye, a rising junior physics major. My research with Dr. Schniepp in Nanomaterials and Imaging Lab this summer will focus on interfacial characterization of graphene/polyamide nanocomposites – studying them on a nanoscopic scale may help us understand why the nanocomposite could be the most promising material of the century.
