Observation of the aggregation behavior of silica sols using laser speckle contrast measurements

Real‐time dimensional change in light‐cured composites at various depths using laser speckle contrast analysis

“…1). Speckle interferometry is a technique that compares speckle patterns of an object at two different states in order to obtain the desired displacement information (37–40). Laser speckle contrast analysis is advantageous because only small amount of sample are required and results are provided with high accuracy.…”

Preparation of silica aerogels using CTAB/SDS as template and their efficient adsorption

“…As their name implies, they are extremely porous materials, consisting more of air than gel. They have low bulk density, high specific surface area, continuous porosities and extremely low thermal conductivity [2][3][4][5][6]. In recent years, there has been concentrated on exploiting the potential applications such as super thermal insulators [7,8], energetic materials [9], catalyst supports [10,11], adsorbent [12] and dielectric materials [11,12].…”

Aggregation behavior in the early stage of sol solutions formation

“…As excellent semiconductors, ITO materials have large variety applications such as optoelectronic devices, sensors and heat reflecting mirrors due to the excellent optical and electric properties [10,11]. For sol-gel derived ITO films, it has been proved that the microstructure and properties of thin films have a great dependence not only on the preparation or heat treatment condition but also on the physicochemical nature and microstructure of starting sols [12,13]. In this research, the aggregation behavior of ITO sol solutions were discussed by transmission electron microscope (TEM), Fourier transform infrared (FTIR) and small angle X-ray scattering (SAXS) techniques, including the morphological structures, the mechanisms of cluster/particle formation and growth.…”
