Structure Rigidity: An Advantage or Disadvantage? Exploring Nature and Applications

1. Liquids are Go

2. Liquids are Go • Solid state – main advantage – exact structure rigidity – Q is this an advantage???? Questionable!!! – look at Nature - Us

3. Liquids are Go • Solid state – main advantage – exact structure rigidity – Q is this an advantage???? Questionable!!! – look at Nature - Us • Disadvantage – no structural flexibility – no ability to respond to variable “environmental” challenges – example Haemoglobin

4. Liquids are Go • Solid state – main advantage – exact structure rigidity – Q is this an advantage???? Questionable!!! – look at Nature - Us • Disadvantage – no structural flexibility – no ability to respond to variable “environmental” challenges – example Haemoglobin • Quantum dots – presently essentially no exact structure control also surface reconstruction issues with which to contend.

Questionable!!! – look at Nature - Us • Disadvantage – no structural flexibility – no ability to respond to variable “environmental” challenges – example Haemoglobin • Quantum dots – presently essentially no exact structure control also surface reconstruction issues with which to contend. • Plastic electronics - Phase separation – random domain topography – reminiscent of liquid crystal domains!
