Assembly of Foldable 3D Microstructures Using Graphene Hinges

Direct-write Self-assembly of 3d Colloidal Microstructures

We present a direct-write technique for assembly of microscale 3D colloidal crystals on substrates. We use a custombuilt high-resolution liquid manipulation system to dispense colloidal suspensions through a capillary tip. Using this system, we establish a liquid bridge between the capillary tip and a temperature-controlled substrate, initiating crystal growth upward from the substrate. We demo...

Evolving 3D microstructures using a Genetic Algorithm

At the last international meeting on recrystallisation and grain growth there was general consensus that there was a need to incorporate experimental microstructures as starting configurations for computer models of various kinds. In two dimensions (2D) this is relatively straight forward since microstructures can be imaged in 2D at various length scales by a number of well know techniques such...

Hierarchical graphene nanocones over 3D platform of carbon fabrics: a route towards fully foldable graphene based electron source.

A three dimensional field emitter comprising hierarchical nanostructures of graphene over flexible fabric substrate is presented. The nanostructuring is realized through plasma treatment of graphene, coaxially deposited over individual carbon fiber by means of simple aqueous phase electrophoretic deposition technique. Hierarchical graphene nanocone, acting as a cold electron emitter, exhibits o...
