Uniform discotic wax particles via electrospray emulsification

Synthesis and anti-fungal effect of silver nanoparticles–chitosan composite particles

“…Most of the relative standard deviations of the sphere diameters observed at various concentrations of AgNO 3 were less than 10%, indicating that the manufactured spheres met the typical criterion for monodispersity. 46 Results shown in Figure 2 illustrate the composite spheres fabricated with low concentrations of AgNO 3 were slightly flattened in contact with the plate bottom, and thus they became slightly enlarged when measured by a top view. This phenomenon occurred because of fewer silver nanoparticles decreasing the mechanical strength of the spheres.…”

Bioinspired assembly of surface-roughened nanoplatelets

“…The spontaneous organization of nonspherical colloids has attracted great recent interest due to the wide range of potential applications of the resulting assemblies in photonic crystals [1][2][3][4], metamaterials [5], surface-enhanced Raman scattering sensors [6], and reinforced nanocomposites [7][8][9], as well as fundamental studies of liquid crystal phase transitions [10][11][12][13] and particle packing [14][15][16]. Among a large variety of nonspherical colloids, platelet particles are particularly interesting as they enable the bottom-up assembly of layered nanocomposites that mimic the nacreous layer of mollusk shells [17][18][19].…”

Brownian dynamics of colloidal microspheres with tunable elastic properties from soft to hard

“…Oil droplets are then prepared at T ≥ 50°C by shear rupturing of a crude emulsion in a custom made Couette cell [25] and subsequent size fractionation using depletion induced creaming [23,26]. We note that uniform discotic wax particles can also be produced via electrospray emulsification [27]. In our case, however, the resulting suspension is composed of spherical droplets having an average diameter = R 2 3.36μm and a size polydispersity in the number distribution of ≃ R R Δ / 0.195, Fig.…”
