Monolayers: Quick, Large‐Area Assembly of a Single‐Crystal Monolayer of Spherical Particles by Unidirectional Rubbing (Adv. Mater. 27/2014)

Unidirectional rubbing of a dry powder between two flat rubbery substrates enables quick large-area single-crystal monolayer assembly of microparticles. The rubbing process is applicable to curved surfaces, as shown here in this frontispiece. Various parameters for the rubbing conditions, such as pressure, rubbing speed, and adhesion energy of substrate, are discussed in detail by U. Jeong, J. Myoung, and co-workers on page 4633.
