Cubosomes are dispersed nanostructured particles of cubic phase liquid crystal that have stimulated significant research interest because of their potential for application in controlled-release and drug delivery. Despite the interest, cubosomes can be difficult to fabricate and stabilize with current methods. Most of the current work is limited to liquid phase processes involving high shear dispe...... hiện toàn bộ

Ternary composite with immobilization of Fe2O3 nanoparticles (NPs) onto porous polydopamine-reduced graphene oxide framework, abbreviated as Fe2O3@PDA-RGO, was fabricated via a simple, scalable and cost-efficient hydrothermal reaction. The as-prepared 3D Fe2O3@PDA-RGO nanocomposite provides a specific surface area of 119.9 m2 g-1 on account of the well-dispersed Fe2O3 NPs (~35 nm) onto the PDA-RGO...... hiện toàn bộ
Synthesis of magnesium-based binary powders with high reactivity using a coprecipitation methodSpringer Science and Business Media LLC - Tập 23 - Trang 1-17 - 2021

The solid-phase reaction method for preparing forsterite (Mg2SiO4) using the MgO and SiO2 powders has the disadvantages of high reaction temperature, long reaction time, and inhomogeneous reaction depending on the particle size of MgO. Therefore, MgO-based powders with a high reactivity were synthesized using a coprecipitation method with substitutional elements (Mn or Ni), and the effects of proc...... hiện toàn bộ
Hollow platinum-gold and palladium-gold nanoparticles: synthesis and characterization of composition-structure relationshipSpringer Science and Business Media LLC - Tập 24 - Trang 1-15 - 2022
Gisella Liliana Lucero Lucas, Henry Romanus, Adriana Ispas, Andreas Bund
Hollow palladium-gold (PdAu) and platinum-gold (PtAu) alloy nanoparticles (NPs) were synthesized through galvanic replacement reactions. PdAu NPs denoted PdAu-99.99 and PdAu-98 were produced using palladium precursors with different purity degree: Na2PdCl4 ≥ 99.99% and Na2PdCl4 98%, respectively. The effect of the addition time of the gold palladium precursor solution on the size of the generated ...... hiện toàn bộ
Green synthesis of Au nanoparticles using potato extract: stability and growth mechanismSpringer Science and Business Media LLC - Tập 16 - Trang 1-15 - 2014
D. N. Castillo-López, U. Pal
We report on the synthesis of spherical, well-dispersed colloidal gold nanoparticles of 17.5–23.5 nm average sizes in water using potato extract (PE) both as reducing and stabilizing agent. The effects of PE content and the pH value of the reaction mixture have been studied. Formation and growth dynamics of the Au nanoparticles in the colloids were studied using transmission electron microscopy an...... hiện toàn bộ
