Nanomaterials and Properties of Nanomaterials Video Lecture from Chapter Surface Chemistry of Subject Chemistry Class 11 for HSC, IIT JEE, CBSE & NEET. thermal evaporation technique is a simple process in which condensed or pow-der source material is vaporized at elevating temperature, and then the resultant vapor phase condenses at certain conditions (temperature, pressure, atmosphere, substrate, etc. Silver nanoparticles have unique optical, electrical, and thermal properties and are being incorporated into products that range from photovoltaics to biological and chemical sensors. 10 nm the decisive) factor of the microstructure. Engineered nanoscale materials or nanomaterials are materials that have been purposefully manufactured, synthesized, or manipulated to have a size with at least one dimension in the range of approximately 1 to 100 nanometers and that exhibit unique properties determined by their size. One important implication for our discussion is the flow of thermal energy. These materials often have special properties resulting from their size, shape, and chemical composition. This may be ascribed to the unique physicochemical properties of nanomaterials as compared to bulk materials, such as soil or dust, or volatile chemicals, such as benzene, PAHs, and TCE. Nano can refer to the fundamental particle size, to the distance across which phenomena occur, or. Nanotechnology has opened up new frontiers in materials science and engineering. Nanomaterials 2017, 7, 191 2 of 13 tunable localized surface plasmon resonance in the visible and NIR regions [10]. 3 Applications of Nanoparticles a) Silver nanoparticles have good antibacterial properties, and are used in surgical.
