Abstract

3

Nature perfected nano technology by evolution overmillions of years. Current technology provides us the

ability to engineer at nano meter level to mimic nature

and develop nano technology enabled products.

Nanomaterial, Nano medicine, Nano electronics and

Nano engineered surfaces can revolutionize the industryfor breakthrough products and economic development.

The simulation based engineering design as a tool for cost

effective Industrial innovation will be outlined. An

overview of multiscale and multiphysics modeling toenable Nanotechnology Innovation will be given. Real life

industrial examples to link nano discoveries to macro

engineering applications for business benefit

quantification will be detailed.

Simulation is considered third pillar of Science &Technology

Simulations has No Cost constraints, harsh/unrealisticparameter range, EHS concerns.

Development in mathematical models, computing

resources

Reliable, efficient and affordability is the key driver for

Concurrent Product Development and growth

Multiscale Modeling

Multiscale model is amathematical model

formed by combining

partial model at different

length and time scales.

Efficient linking is critical

Away from predictingknown properties towards

new materials with novel

properties.
