I am trying to prepare the encapsulated PCMs in which the core is paraffin wax and the shell is Silica using the sol-gel method. I am following this paper; Article Synthesis and Characterization of Microencapsulated Paraffin...
Looking for a detailed procedural explanation. Thank you

The article that you submitted yourself describes in detail the preparation of capsules, which consists of two stages.
1.Preparation of the Paraffin Oil–Water Emulsion
2.Preparation of Microencapsulated Paraffin Microcapsules with an SiO2 Shell
If you're looking for a detailed explanation of synthesis, it's there. You may not be aware of their use.
Imagine that you have decided to create a wood chip board production with such capsules. When heated in the sun during the day up to 50-55 0C, paraffin absorbs heat and melts, and at night at 10 0C it gives off heat and hardens. In this way, you use the energy of the sun to heat your house or greenhouse.

Experimenters sometimes do not write down the details of obtaining the material, leaving the secrets to themselves. You can trust the experiment. Good characterization and thermodynamic data are presented.
1. The emulsion must be stable.Make an emulsion , let it stand and so choose the best mixing option.
2. Prepare only beads with the sol-gel method to master the method. Only after mastering these procedures, proceed to the synthesis of core/shell particles.
3. Write to the authors of the article at the same time. Maybe they will reveal to you the features of the experiment.
Dear Muhammad Ghufran,
Incase you require detailed explanation of synthesis for silica encapsulation paraffin. You can find more details in
