"Spicy world of NanoScience" since 2007

Designed for iPhone, iPad and iPodTouch device compatibility by independent developer and Associate Professor Peter Burke [University of California at Irvine], the iNanotube™ 1.1 for iOS app is where the rubber meets the road in the forging ahead towards advanced STEM pedagogical paths.
This thoroughly-engaging, atomic-scaled wire visualization teaching tool is instructive - for example - in conveying the plethora of technical possibilities in the creation of different diameters and spiral patterns. Utilizing SmartPhone and Tablet media, users interface with multitudinous combinations of (n,m), [about 2/3 of which result in semiconducting nanotubes, and the other approximate 1/3 producing metallic nanotubes].
By means of this disruptively educational implementation, students graphically explore the making of multitudinous kinds of carbon nanotubes and very specific crystal structures via ab initio calculations of the atomic positions - performed by the iPhone™ mathematics processor - by diameter and spiral pattern.
Following self-directed manipulations, constructions, and design of graphical animations of elemental, essential graphene lattices morphing into carbon nanotubes, students interactively learn how the (n,m) index determines nanotube diameter and spiral winding pattern, and come away with clear, clean, intuitive (even intimate) comprehension of the inter-relationships between the (n,m) index, crystal structures, structural bonding, and fundamental atomic components.
iNanotube™ didactically demonstrates - in intricate, virtualised, representative detail- novel concepts of atomic control. Its highly innovative features include:
Anticipated by Burke are "future design of atom-by-atom constructions of many nanotechnology objects such as graphene and other materials".
