Achieving homogeneity in nanomaterials often involves precise synthesis techniques and rigorous quality control measures. Some methods include: - Chemical Vapor Deposition (CVD): This technique allows for the uniform deposition of materials at the nanoscale. - Sol-Gel Process: This involves the transition of a system from a liquid "sol" into a solid "gel" phase, ensuring uniform particle distribution. - Ball Milling: This mechanical process can produce homogeneous nanoparticle mixtures by breaking down larger particles and thoroughly mixing them.
