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.
Posted on. (Answer #1). Nanochemicals are chemicals generated by using nanomaterials, materials which have size on nanometer dimensions. The nanochemicals are used in a variety of applications, including chemical warfare, bicycle manufacturing, armor design and military weapons.The most commonly used and studied nanochemical is carbon nanotubes, that are used extensively in industry for applications such as stronger materials (stronger bicycles).pecialized materials are designed to perform a specific task or function. Applications include electronic equipment (high purity silicon and germanium), machine tools (high tungsten high carbon steel), dental filling (dental amalgam), etc.
