Nanomaterials and how are they made
Witryna13 kwi 2024 · In general words, nanomaterials are inferior to bulk materials in terms of thermal and electrical conductivity. According to the classical free electron theory of metals, electrical conductivity results from the free movement of electrons within a … WitrynaNanomaterials can be produced naturally, as a by-product of the combustion reaction, or they can be deliberately engineered to perform specific functions. These materials can have different physical and chemical properties from their bulkcounterparts. Nanomaterials are chemicals that are manufactured and used on a very small scale.
