This leads to the second law of thermodynamics and the definition of another state variable called entropy. The second law stipulates that the total entropy of a system plus its environment can not decrease; it can remain constant for a reversible process but must always increase for an irreversible process.
Nanotechnology is used in many commercial products and processes, for example, nanomaterials are used to manufacture lightweight, strong materials for applications such as boat hulls, sporting equipment, and automotive parts.anomaterials are all nanoscale materials or materials that contain nanoscale structures internally or on their surfaces. These can include engineered nano-objects, such as nanoparticles, nanotubes, and nanoplates, and naturally occuring nanoparticles, such as volcanic ash, sea spray, and smoke.
Nanotechnology is the field that uses microscopic processing techniques to produce various materials and components. Nanomaterials are used in many industries including electronics and mechanical design to produce useful items, and their applications can be seen in almost all the engineering fields.here are two methods are used to produce nanomaterials. One is called the âtop down methodâ and the other is the âbottom up method.. In the first method very small components are produced using larger parts of the material.
