Question

Select any 3 applications from among: biomedical, nuclear, energy, aerospace, automotive, electronics, photonics or sports. For each application, identify one product or a component of a product used for that applicatio made of ONE material, for which new materials are being used or being considered for use.

Answer 1

1.for biomedical application to identify one component of product used for that application made of one material for which new material being used:

biomaterials have been used to augment tissue function & treat diseases or injuries for thousands of years .

-whether selecting coral or wood for dental implants or fabrics for sutures .

as one example , vascular stents have been widely used to open blocked vessels & restore blood flow to ischemic tissues , & the design of this stents has significantly evolved with time .With the developement of nitinol , a metal alloy of nickel & titanium with unique shape memory & superelastic properties , stent design has improved to be implanted with simpler ,minimally invasive procedures & to maintain functions for longer period of time .

2.for nuclear application to identify one component of product used for that application made of one material for which new material being used

liquid fuels are liquids containing dissolved nuclear fuel & have been shown to offer numerous operational advantages compared to traditional solid fuels approaches .

liquid fuel reactors offers significant safety advantages due to their inherently stable 'self- adjusting' reactor dynamics .

molten salts

molten salt fuels have nuclear fuel dissolved directly in molten salt coolants,molten salt fuel reactors such as liquid fluoride thorium reactor (LFTR).the liquid fuel for molten salt reactor was mixture of lithium ,beryllium,thorium & uranium flourides . It has peak oprating temp 705 ^oC in experiment but could used at higher temperatures.

3.for energy application to identify one component of product used for that application made of one material for which new material being used

Over past few decades ,the field of SCIence & Engineering have been seeking to develop new & improve type of energy technologies that have the capability of improving life all over world.they are developing energy application of nanotechnology.

field related to energy is nanofabrication.
