Kivonatos ismertetes:

The two most important events in Materials Science and Engineering in the 
past 
50 years have been the introduction of surface free energy as a tool for 
creating new materials and the cracking of the genetic code of the entire 
biosphere which is underway and is creating a tidal wave of information that 
is 
going to transform our technology to the core. These two events are 
intertwined 
at the most fundamental level in that the key to the assembly of complex 
nanomachines lies within each of our cells. The ribosome has done its 
evolutionary job of getting us to 2006 and its now time to turn this 
marvelous 
machine loose to manufacture materials and machines that have nothing to do 
with evolution. 

n this talk I will start with a fundamental examination of the nature of 
nanomaterials and show how Z.L. Wang has made many beautiful structures of 
ZnO. 
We will then turn to the applications nanowires, nanobelts and carbon 
nanotubes 
to the making of field-effect transistors, lasers, self-cleaning surfaces and 
nano-sized electrical generators. 

I would then like to explore applications of using the machinery of the 
living 
cell to manufacture nanostructures via biomimetics to use structures that 
already exist in nature - collecting the low hanging fruit. Nature provides 
elegant examples of organisms that generate three-dimensional structures with 
complex patterns from the macro-scale to the nanoscale. Lastly we will look 
at 
methods to take genes from species producing desirable structures, perhaps 
modify them, and then retrofit them onto a compliant single celled bug who 
will 
become a manufacturing unit. By mid 21st century I believe that we will know 
enough genetics, biochemistry and materials science to computer design genes 
to 
produce devices from nanomachines to complete computer systems using the 
machinery in each of our cells.
