Design of a highly ordered and uniform porous structure with multisized pores in film and particle forms using a template-driven self-assembly technique

Preparation of Polystyrene Spheres Using Surfactant-Free Emulsion Polymerization

“…This condition will retard the nucleation stage. Then, because the Brownian motion of nuclei is slower than other components (Nandiyanto et al, 2010), so that the nuclei is more tended to increase in weight by the interaction and coalescence of initiator radicals and the free monomer, than in number (Nandiyanto et al, 2012). So that, in the bigger monomer concentration there are more free monomers to coalesce and produces bigger particle.…”

Liquid-phase Synthesis of CaF₂ Particles and Their Low Refractive Index Characterization

“…Impact from the change of particle type to the material performance was confirmed. 14) An increase in the calcium amount would increase the refractive index of the precursor. The particles with a Ca:F ratio of 1:2 had the lowest value of refractive index value (close to the theoretical refractive index of a single crystalline CaF2 monolayer (1.433 30) )), while particles with a ratio of 15:1 had the highest.…”

“…27,28) This reason makes that the analysis of refractive index is the best to confirm the effect of reactant composition, size, and morphology on material properties. 14) To measure the refractive index value, the conventional Lorenz-Lorentz theory is typically used 29) :…”

“…Besides, we also successfully developed a process for the synthesis of particles with controllable size and morphology using a spray method. [11][12][13][14][15][16][17][18][19][20][21][22][23][24] Here, we report the synthesis of CaF2 particles with controllable size and morphology using the liquidphase synthesis method. Different from other CaF2 synthesis methods, the synthesis was based on the reaction of Ca 2 and F ions in an aqueous solution in the absence of additional components (polymers, surfactants, chemicals, etc.).…”

Influences of Size and Amount of Colloidal Template and Droplet Diameter on the Formation of Porous-structured Hyaluronic Acid Particles

“…Until now, many methods have been developed to produce porous pharmaceutical particles (Faure et al, 2001;Nandiyanto et al, 2014;Nandiyanto et al, 2013;Nandiyanto & Ukuyama, 2011;Nandiyanto et al, 2010). One of the best method for fabricating porous-structured pharma-ceutical particles is combination of spray drying and templating method (Nandiyanto et al, 2019).…”
