Synthesis

Arc Growth Methods

Methods of arc production in BN, Carbon, and doped carbon nanotubes are available within the facility.  Equipment includes a "Large scale" kratchmer system capable of gm/day quantities in both MWNT and SWNT formats.


Chemical Vapor Deposition

Most of the growth effort at NanoTech focusses on new CVD techniques.  Doped carbon nanotubes, nanowires, and patterned systems of nanoparticles can generally be created at temperature between 750 C and 1100 C.  Substrates we use are silica and sapphire, usually, though more electro-active ceramics are now under study.


Pulsed Ablation

High energy, pulsed laser/plasma ablation and growth of nanostructures is currently under development at the Center.  Based on high power YAG lasers and pulsed plasma torch: carbon, oxide, and other ceramic materials can be created in nanophase.


Polymer Synthesis

The NanoTech has a synthesis lab for conjugated polymers used in OLED and OPV device studies. Instrumentation includes:


Multiple solvent stills

Glovebox for air/moisture sensitive reactions

Biotage Flash 100 Flash Chromotagraphy system

Centrifuge

Ultra-fine Scales

A large assortment of glassware and reactors

Cold chemical storage

Rotovap

Closed circuit chiller system


Electrospinning

Single injector electrospinning with mandrel or plate takeup system.

The synthesis and characterization of new materials that have been engineered at the nanoscale to have properties that do not normally occur in nature; this is at the heart of the nanosciences. The confinement of carriers, alignment of bonding, tailoring of internal degrees of freedom, phase coherence - these are all new phenomena that can be expected at the nanoscale. 

Our nanoSynthesis efforts have focused on a wide range of materials: carbon, ceramics, metals - polymers, nanotubes, nanoparticles.  There is a wide range of experience within the NanoTech Center on the creation of nearly any nano-materials form.
