Optical microscopy observations of hydrogel, alcogel and aerogel samples had been carried out employing an upright Olympus microscope BX-fifty one. A electronic digicam Nikon D50 mounted within the microscope and smaller-magnification (two× or 4×) Olympus goals were used to choose pictures of drinking water droplets on the surface of SiCellA movies, which permitted for measuring a Get in touch with angle and pinpointing surface wettability employing ImageJ program (freeware, Nationwide Institutes of Health and fitness). Refractive index values of SiCellA aerogels were received by measuring a least deviation angle by a prism produced of the material61,62,sixty three, the place a laser beam from the 632 nm helium–neon laser (Edmund Optics) was deviated by an aerogel prism put on a rotating holder (Olympus).
