Aligned HNT for Abrasion Resistance in Solar Cell Coatings

Song K., Polak R., Askar K.A., Rubner M.F., Cohen R.E., MIT, US

Halloysite nanotubes (HNT), a kind of naturally formed ceramics, encompass high aspect ratio, stiffness and low cost while remain understudied about their coating usage. Theoretical and experimental results have shown a modulus as high as [...]

Facile Spray Coating in Preparing Anisotropic Composites

Song K., Polak R., Abdalla Askar K., Rubner M.F., Cohen R.E., MIT, US

Anisotropy has been taken advantage in composites to achieve specific mechanical, electrical, magnetic and other functional properties. In composite mechanics, orientation of fiber in polymer matrix will reinforce the composites to the greatest potential along [...]

Engineering superhydrophobic and superoleophobic surfaces

Tuteja A., Choi W., Mabry J.M., McKinley G.H., Cohen R.E., Massachusetts Institute of Technology, US

The combination of surface chemistry and roughness on multiple scales imbues enhanced repellency to the lotus leaf surface when in contact with a high surface tension liquid such as water. This understanding has led to [...]
