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.
Use of nanoparticles. Nanoparticles are used in products that are currently available. 1  sports equipment: nanoparticles are added to materials to make them stronger whilst often being lighter. 2  They have been used in tennis rackets, golf clubs and shoes. 3  clothing: silver nanoparticles have been added to socks.here are some concerns that nanoparticles may be toxic to people. They may be able to enter the brain from the bloodstream and cause harm. Some people think more tests should take place before nanoparticles of a material are used on a wider scale.
