1. NANO Materials

2. Nanomaterials have many industrial and medicinal applications Drug delivery:   Nanomaterials can be used to target specific tissues or organs. This can decrease drug toxicity and increase patient compliance. Metallic nanoparticles have been used in cancer treatment. Medical devices:   Nanomaterials are used in synthetic bone grafts, wound dressings, and medical instruments. Pharmaceuticals:   Nanomaterials can improve drug safety, efficacy, and bioavailability. Diagnostics:   Nanomaterials can be used for medical imaging and diagnosis.

3. Carbon Nanotubes applications Medical Carbon nanotubes can be used as near-infrared agents for selective cancer cell destruction. Civil engineering Carbon nanotubes can improve the mechanical properties of soil cement matrices. Fuel cells Surface modified carbon nanotubes can help catalyze electrode processes and improve the performance of electrolyte membranes. Satellites Carbon nanotubes can increase the performance of antennas by twenty times. Electronics Carbon nanotubes can be used as a transparent conductive film in flexible displays and touch screens. Water treatment Carbon nanotubes can be used in composite membranes for seawater or brine desalination, oil-water separation, and removal of heavy metal ions.

4. SMART MATERIALS PIEZOELECTRIC MATERIALS SHAPE MEMORY ALLOYS

5. Piezoelectric Effect is the ability of certain materials to generate an electric charge in response to applied mechanical stress. 

6. Shape memory alloys Shape memory alloys are a unique class of alloys that have ability to 'remember' their shape and are able to return to that shape even after being bent. nickel/ titanium and copper/ aluminium/ nickel have two remarkable properties – pseudo-elasticity (appearing to be elastic) and shape-retention memory.

7. Spectacle frames . Surgical plates for joining bone fractures and surgical wires to replace damaged tendons.

8. The Elephants of Materials Science: SMAs Never Forget Their Shape

9. A coil made out of a nickel-titanium alloy

10. Shape-Memory Alloy The austenite is stiffer and has lower volume. Heating SMA wire causes it to contract with some force. Strains of 3-5% are typical.

11. Shape-Memory Alloy Nitinol has the following attributes: Martensite Austenite Stiffness GPa 28 75 Resistivity 76 82 Transition T 62-72 88-98

12. Aerospace: SMAs can be used as actuators and sensors in aircraft and space vehicles. They are lighter and can save energy compared to mechanical actuators. Automotive: SMAs are used in many automotive systems, including: Adjustable mirrors Windshield wipers Door locks Smart bonnets Tumble flaps Governor valves Fog louvers Hatch vents Medical: SMAs are used in many medical devices, including: Vascular stents Artificial joint implants Orthodontic braces Orthopaedic wire Robotics: SMAs can be used as thermal-mechanical actuators. Electronic devices: SMAs can be used as actuators or connectors.
