1 NANOTECHNOLOGY THE KEY TO SUSTAINABILITY Ankara, Oct. 4, 2010
2 THIS IS NOT MEANT TO BE A GREEN CRUSADE IT IS A REMINDER THAT SCIENCE PROVIDES WHAT MANKIND NEEDS BUT MANKIND HAS TO MAKE THE CHOICE
3 WORKING AT AN EVER SMALLER SCALE SHAPED THE TECHNICAL REVOLUTIONS OF THE PAST
4 TECHNICAL REVOLUTIONS & MINIATURIZATION GEO REVOLUTION 1492 THE WORLD SCALE INDUSTRIAL REVOLUTION FROM MACRO- TO MICRO SCALE MECHANICS, ELECTRICITY 1698, 1769 IT REVOLUTION 1925, 1934, 1945, 1947 MICRO SCALE MICRO-ELECTRONICS, MICRO-MECHANICS NANO REVOLUTION? NANO SCALE NANO-ELECTRONICS, -MECHANICS, -CHEMISTRY, -BIOLOGY.
5 TECHNICAL REVOLUTIONS GEO REVOLUTION EXPLORE THE WORLD THE WORLD SCALE INDUSTRIAL REVOLUTION FROM MACRO- TO MICRO SCALE MECHANICS, ELECTRICITY IT REVOLUTION PHYSICAL TASKS SIMPLE MENTAL TASKS MICRO SCALE MICRO-ELECTRONICS, MICRO-MECHANICS NANO REVOLUTION? COMPLEX MENTAL TASKS NANO SCALE NANO-ELECTRONICS, -MECHANICS, -CHEMISTRY, -BIOLOGY.
6 THE CONFUSION ABOUT SUSTAINABILITY RESOURCES: LESS RESOURCES IN A NO GROWTH WORLD? STAGNANT RESOURCES IN A GROWING WORLD? A LITTLE BIT MORE RESOURCES FOR MUCH GROWTH? MUCH LESS RESOURCES FOR NEGATIVE GROWTH? WORK: DO A JOB MORE EFFICIENTLY DON T DO SOMETHING AT ALL LIFE: IS POPULATION GROWTH SUSTAINABLE? IS AGING SUSTAINABLE
7 SMALL IS POWERFUL SMALL RULES LARGE
8 MICRO (ELECTRONICS) RULES TODAY s TECHNICAL WORLD NANO IS THE SCALE OF ATOMS AND MOLECULES AND RULES LIVING NATURE
9 NATURE is the PERFECT NANO-SYSTEM THE FUNDAMENTAL SHAPES, MOTIONS, PROCESSES HAPPEN TO BE ON the nm SCALE AND ARE SYNTHEZISED TO MICRO- AND MACRO- SHAPES, MOTIONS, PROCESSES THE TECHNICAL STRATEGY OF LIVINGATURE IS SENSE & ACTUATE: SMALL BY SMALL WEAK BY WEAK MANY BY MANY } AT THE NANO LEVEL e.g. ARRAYS OF NANOSENSORS
10 SMALL IS POWERFUL SMALL RULES LARGE SMALL IS SUSTAINABLE
11 SMALL MEANS SUSTAINABLE LITTLE ENERGY CONSUMPTION
12 REDUCTION OF ENERGY PER LOGIC OPERATION: 10 12
13 Nevertheless THE ENERGY BILL OF DATA PROCESSING INCREASED to: 300 BILLION USD / YEAR TOTAL ENERGY REQUIREMENT of a PERSON: 120 USD/YEAR THINKING of a THINKER: 15 USD/YEAR
14 SMALL MEANS SUSTAINABLE LITTLE ENERGY CONSUMPTION LITTLE BUT BEST SUITED MATERIAL
15 YEARLY PRODUCTION OF TRANSISTORS: QUINTILLION 1 BILLION PER PERSON WITH THE SMALLEST RADIO TUBES WE WOULD STAND KNEE-HIGH IN THEM
16 YEARLY ENERGY CONSUMPTION OF RADIO TUBES OF 1 WATT 2 x J 700 x YEARLY WORLD ENERGY CONSUMPTION
17 SMALL MEANS SUSTAINABLE EXAMPLE: COMPUTING LITTLE ENERGY CONSUMPTION LITTLE AND BEST SUITED MATERIAL SMALL FOR EXCELLENT PERFORMANCE
18 SMALL FOR EXCELLENT PERFORMANCE: SUCCESS of MICRO-ELECTRONICS SMALLER, FASTER, CHEAPER SMALLER : FASTER : CHEAPER :
19 HEAT DISSIPATION PER LOGIC OPERATION JOULE CONTINUATION of MINIATURIZATION MINIATURIZATION IN DATA PROCESSING THE SUCCES OF THE PAST THE CHALLENGE END
20 WORKING AT AN EVER SMALLER SCALE COMES TO AN END WHAT NEXT?
21 NANO CANNOT BE JUST AN EXTENSION FROM THE MICRO- TO THE NANO-METER SCALE, IT HAS TO OFFER FUNDAMENTALLY NEW PROSPECTS IN ORDER TO SPARK A REVOLUTION AND IT DOES INDEED!
22 THE CONTINUATION OF MINIATURIZATION FROM MICRO TO NANO IS DISCONTINUOUS IT HAPPENS IN DISRUPTIVE STEPS
23 NANO is DIFFERENT IT IS THESE DISRUPTIVE STEPS WHICH MAKE THE DIFFERENCE AND POSE THE CHALLENGES
24 DISRUPTIVE STEPS FROM MICRO TO THE ATOMIC AND MOLECULAR NANO SCALE ANALYTICS COMPONENT SIZE
25 DISRUPTIVE STEP in COMPONENT SIZE TRANSISTOR SCALABLE MACRO 30 nm? NEW NANO ELECTRONIC COMPONENTS are INTRINSICALLY MUCH SMALLER: SINGLE ELECTRON TRANSISTOR ( at R.T.) BALLISTIC TRANSPORT (at R.T.) SPIN BALISTICS, SPINTRONICS MOLECULAR ELECTRONICS 1-3 nm 1-5 nm 1-2 nm 1-5 nm NOT SCALABLE
26 DISRUPTIVE STEPS FROM MICRO TO THE ATOMIC AND MOLECULAR NANO SCALE ANALYTICS COMPONENT SIZE PROPERTIES & FUNCTIONS
27 DISRUPTIVE STEPS in PROPERTIES & FUNCTIONS d < MEAN FREE PATH l m : d < WAVE LENGTH : d < l m, : d < e2/kt: ADHESION > GRAVITY : BALLISTIC REGIME, SPIN-TRONICS NEAR FIELD, Q-WELLS,- WIRES, - DOTS QUANTUM CONDUCTION COULOMBE BLOCKADE (d RT 2nm) ATOM & MOLECULE MANIPULATION N BULK N SURF N EDGE : NOVEL MECHANICAL, CHEMICAL, ELECTRICAL PROPERTIES d ~ nm-range : REVERSIBLE PLASTIC DEFORMATION, ANTI-WETTING THROUGH NANO ROUGHNESS
