NanoTechnology Talks - October 2011

Nanotechnology is best understood as a convergence of many technologies -
material sciences, physics, life sciences, chemistry, electrical engineering, computer science, information technology, medicine - every discipline is impacted by nanotechlogy.

In the five 90-minute talks, I had to choose my material very carefully
to provide a good comprehensive feel for the subject.
I have prepared a list of topics that
I shall be discussing in the talks starting Saturday 1st October in the lovely
lecture theatre in James Watt Building, East Kilbride Technology Park.

Talk 1: Introduction and Nanoparticles
Recent trends in technologies
Nano means dwarf; scale of things
Nano-objects behave differently
Reactivity is skin deep
Nano particles and enormous surface area
Some current examples of nanoparticles in use
Catalysis
Nanoparticles are good catalysts
Zeolites – molecular sieves

Talk 2: Seeing Nano Objects
Types of microscopes
Optical microscopes
Wave nature of the electron
Magnetic lens
Electron microscopes
Quantum tunnelling effect
Scanning tunnelling microscope
Atomic force microscope
Examples of images of nanostructures

Talk 3: Making Nano Objects; The digital Revolution
Shrinking device sizes
Top-down and bottom-up Manufacturing
Lithography
Self assembly
The information Technology Revolution – historical
Transistor and Integrated Circuit
Moore’s first and second laws – trends and limits
About robots
Examples: Nuclear plant safety, Electronic noses

Talk 4: Nature’s Nanotechnology
What has nature given us?
Photosynthesis
Artificial leaf
DNA – the molecule of life
Watson and Crick model of the DNA
Genes - coding for proteins; How Many? Junk DNA
Making new software for the cell
Recombinant DNA Technology
Learning from Nature’s achievements

Talk 5: The Story of Carbon; Nanomedicine
Many forms of carbon
Graphite and graphene
Bucky Balls – what are they and some applications
Carbon nanotubes – what are they and some applications
The space elevator
Nanomedicine
Miniature computers
Probing the cell with nanoprobes
Computerised Tomography with nanotube X-ray source
