What are the Challenges in Surface Area Measurement?
Despite the availability of advanced techniques, measuring the surface area of nanomaterials poses several challenges:
1. Aggregation and Agglomeration: Nanoparticles tend to aggregate, which can complicate accurate surface area measurements. 2. Sample Preparation: Proper sample preparation is critical to avoid introducing artifacts that can affect the results. 3. Instrument Calibration: Regular calibration of instruments is necessary to maintain measurement accuracy.
