what is a CNT (Carbon nanotube)
a tubular form of carbon with diameter as small as 1 nm. Length: few nm to microns.
the properties of CNT
Young’s modulus over 1 Tera Pascal
as stiff as diamond
and tensile strength ~ 200 GPa
CNT Applications
High strength composites
Cables, tethers, beams
Multifunctional materials
Functionalize and use as polymer back bone - plastics with enhanced properties like “blow molded steel”
Heat exchangers, radiators, thermal barriers, cryotanks
Radiation shielding
Filter membranes, supports
Body armor, space suits
CNT Applications Challenges
Control of properties,
characterization
Dispersion in host materials
Large scale production
Application development
Nanotechnology in Transportation
More efficient catalytic converters
Thermal barrier and wear resistant coatings
Battery, fuel cell technology
Wear-resistant tires
High temperature sensors for ‘under the hood’; novel sensors for “all-electric” vehicles
High strength, light weight composites for increasing fuel efficiency
Nanotechnology in Medicine
New formulations and routes for drug delivery, optimal drug usage
More durable, rejection-resistant artificial tissues and organs
Sensors for early detection and prevention
Goals of Nanotechnology Research
Research and technology development aimed to understand and control matter at dimensions of approximately 1 - 100 nanometer
Ability to understand, create, and use structures, devices and systems that have fundamentally new properties and functions because of their nanoscale structure
Ability to image, measure, model, and manipulate matter on the nanoscale to exploit those properties and functions
Ability to integrate those properties and functions into systems spanning from nano- to macro-scopic scales
The acronym LoC means?
Lab on a chip
Isotropic etching
removes material in all directions equally
anisotropic etching
removes material differently depending on direction.
