Dry Powder Precursors of Cubic Liquid Crystalline Nanoparticles (cubosomes)Springer Science and Business Media LLC - Tập 4 - Trang 297-311 - 2002
Patrick T. Spicer, William B. Small, Matthew L. Lynch, Janet L. Burns
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

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
