Fundamental Experiment

<p>In order to measure the sizes of nanoparticles with a wide size distribution in a solvent, we developed an optical microscopy system that allows for fluorescence polarization (FP) measurement and optical observation. This system allows the evaluation of nanoparticle sizes over a wide range, because the fluorescent signal intensity is independent of changes in the nanoparticle sizes. In this paper, we describe a fundamental experiment to verify the feasibility of using this system for different sizes of nanoparticles.</p>

High-Resolution Ultrasonic Spectroscopy (HRUS) is a novel analytical technique for non-destructive material analysis for a wide range of samples and processes. This technique is based on precision measurements of velocity and attenuation of acoustical waves at high frequencies propagating through materials. It has considerable advantages over many alternative technologies because it can be applied to systems that are optically opaque and concentrated without the need of any sample preparation. It provides an unprecedented range of new analytical capabilities for research, product development, quality and process control. Applications of this technique include analysis of solution-phase crystallization, aggregation and gelation phenomena, particle sizing, stability of emulsions and suspensions, microstructural transitions and pharmaceutical manufacturing. Here, we review the theory of the HRUS and its applications on crystallization process.
