3rd Global meeting on Nanotechnology and Advanced Materials

A medical device is any kind of gadget electrical/electronic or mechanical that is used to solve any problem that doctor face while treating his patients. From the syringe to the ECG machine all lies under the term medical device. In a broader sense we can say that every equipment that creates ease for medical professional say nurse or doctor while diagnosing any human or animal body part or disease. The lightning instruments you see in the operation theatre are no more than a light source providing just light like one installed in your study room. But light source in the study room or TV lounge is not a medical device but the same in Operation Theatre will be termed as medical device. As far as biomedical material is concerned. So any kind of material that is used in manufacturing of Medical Device is termed as biomedical material. There are international standards that classify the materials that should be used in medical devices.

Polymer Science is a generic term covering the various subdivisions of the subject. Polymer chemists are mostly interested in the task of making plastic substances from their precursor chemicals; by reacting ethylene, propene or other hydrocarbons with catalysts under appropriate conditions Eg high pressure. Plastics or thermoplastics are typically made by free radical chain reactions. In contrast polymer resins or thermosets, another class of man-made polymers, are made by cross linking various reactive momomers or oligomers together, Eg polyurethane paint when spread into a thin film eg on a wall, undergoes a cross linking reaction to form a resin; the crosslinking reaction is induced by atmospheric oxygen. Resins unlike plastics are essentially one big molecule! That's why there are few if any solvents for them. In contrast plastics can be softened with solvents being linear in their structure at the molecular level. The distribution of polymer chain lengths in a gi...

Smart material are those that change in response to changing conditions in their surrounding or in the application of other directed influences such as passing an electric charge through them. Modern products increasingly use them, shirts that change colour with changes in temperature. Smart materials are the materials that have one or more properties that can be significantly changed in a controlled style such as stress, temperature, moisture, pH, electric or magnetic fields. There are many types of smart material some of which are already common. Some examples are as following: Types of smart material Some types of smart materials include: Piezoelectric   - On applying a mechanical stress to these materials it generates an electric current. Piezoelectric microphones transform changes in pressure caused by sound waves into an electrical signal. Shape memory   - After deformation of these materials they remember their original shape and return back to i...

        Materials Science and Engineering (MSE) combines engineering, physics and chemistry principles to solve real-world problems associated with nanotechnology, biotechnology, information technology, energy, manufacturing and other major engineering disciplines.         The interdisciplinary field of  materials science , also commonly termed  materials science and engineering , is the design and discovery of new materials, particularly solids. The intellectual origins of materials science stem from the Enlightenment, when researchers began to use analytical thinking from chemistry, physics, and engineering to understand ancient, phenomenological observations in  metallurgy and mineralogy .            Materials research covers a broad range of topics – the following non-exhaustive list highlights a few important research area...
