The average crystallite size estimated by the broadening of XRPD peaks increases from 2.7 nm to 3.7 nm in the temperature range from 100 °C to 150 °C. HR-TEM images show that nanoparticles are arranged in aggregates with the 60–200 nm size. Theoretical estimation shows that...
For ImageJ and Origin, each historic version was available; here ImageJ 1.53 t bundled with 64-bit and Origin 9.1 32-bit were used to analyze the size distributions from TEM images. 2.2. Synthesis of Silica Nanoparticles The synthesis of SiO2 nanoparticles relies on the classic Stöber ...
