Presentation Transcript

Slide 1: 

WELCOME

NANO TECHNOLOGY : 

NANO TECHNOLOGY ABIMANYU MANNIL SECOND ECE PAAVAI COLLEGE OF ENGINEERING

INTRO & ORIGIN : 

INTRO & ORIGIN Controlling matter on atomic scale. Fabricating with in 1-100 nm. Multi-disciplinary field of nano. Extension of existing science. Plenty of room at the bottom - Richard Feynman. STM & cluster science in early 80’s.

CONCEPTS OF NANO : 

CONCEPTS OF NANO 1 nm = 1 billionth of a meter usage in physics , chemistry , biology space research In medicine Future’s future

APPROACHES : 

APPROACHES Bottom up approach * they arrange smaller components in to more complex. Top down approach * create smaller objects using Larger objects

NANO MATERIALS : 

NANO MATERIALS Applications with morphological features less than one tenth of a micrometer Fullerences – allotropes of carbon graphene sheets rolled – mechanical strength Nano particles – special properties Bending of bulk copper – suspension of materials.

TOOLS AND TECHNIQUES : 

TOOLS AND TECHNIQUES AFM setup

APPLICATIONS : 

APPLICATIONS MEDICINE CHEMISTRY & ENVIRONMENT ENERGY COMMUNICATION HEAVY INDUSTRIES CONSUMER GOODS MEMORY STORAGE

MEDICINE : 

MEDICINE Diagnostics – cell imaging Drug delivery – apt dosage can be given Tissue engineering – repair damaged tissues

INFORMATION & COMMUNICATION : 

INFORMATION & COMMUNICATION Memory storage – cross bar switch Novel semi conductors – GMRR , TMR Novel opto electrics – bandwidth more & high capacity and displays

IMPLICATIONS : 

IMPLICATIONS Effect on society Possible dangers Untraceable destructive weapons Industrial scale projects Exacerbate wealth gap

HEALTH RISKS : 

HEALTH RISKS Silver causes unintended consequences Research in rats Inflammation & stress May cause incurable diseases

FUTURE OF NANO : 

FUTURE OF NANO Eco friendly products Agricultural productivity energy generation Clean manufacturing Smart appliances Improved medicine

CONCLUSION : 

CONCLUSION Mimic natures life Is it possible ? Adaptation of life ! Optimal Nano-technology
