Polymer photonic crystal band-gap modulation using PbS quantum dots

MXenes and polymeric colloids nanocomposites for EMI shielding

“…3), the dimensions of the assembles formed were 1144 nm with a Zeta potential of À28.7 mV. Based on previous reports of our team, 26,[31][32][33][34] for the ST-AA system, the polymer particle dimensions are in the 200-250 nm range for polymerization without MXenes. Thus, the DLS data presents the dimensions of the MXenes polymer colloid aggregates that were identified as polymer colloids bound to the 2D MXenes platelets.…”

Synthesis and characterization of silica–lead sulfide core–shell nanospheres for applications in optoelectronic devices

“…The relevance of Core-Shell nanoparticles has increased exponentially in the last 20 years since these nanostructures have allowed the exploration of a new range of applications that link the chemistry of materials and other areas such as electronics [15], biomedicine [16] and optics [12]. The potential applications of these nanostructures in electronics are particularly interesting, like enhancing photoluminescence and the manufacture of photonic crystals [17][18][19][20]. To achieve a colloidal dispersion containing monodisperse spheres on a nanometric scale was used the Stöber process, this process consists in the preparation of controllable and uniform size silica particles through hydrolysis and condensation of tetraethyl orthosilicate (TEOS) in a water/alcohol solution and using ammonium hydroxide as the catalyst system [21].…”
