Plasma synthesis of large quantities of zinc oxide nanorods / J. Phys. Chem. C
this paper, ZnO nanorods with high yields were successfully synthesized using a radio frequency (RF) thermal plasma system in a one-step, continuous, and scalable way by the thermal evaporation of different zinc compounds, and the aspect ratio of synthesized nanorods could be well controlled by adjusting the feeding rates of starting materials and ...
Evolution of optical phonons in CdS nanowires, nanobelts, and nanosheets
We report Raman scattering from single and ensemble CdS nanowires, nanobelts, and nanosheets. The Raman spectra of nanobelts and nanosheets are notably different from those of nanowires, exhibiting a strong enhancement of the multiphonon response. Moreover, the first-order longitudinal optical (LO) phonon energy systematically increases with increa...
Synthesis of single-crystalline hollow octahedral NiO / Cryst. Growth Des.
We have successfully fabricated single-crystalline hollow NiO crystals with well-defined octahedral morphology. With detailed investigations by using scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and thermogravimetric analysis, we propose a growth mechanism of the hollow octahedra. It is the first report that ho...
Bis-phosphonates-ultra small superparamagnetic iron oxide nanoparticles: a platform towards diagnosis and therapy.
Published in Chemical communications (Cambridge, England)
A new type of multifunctional magnetic nano-platform for diagnosis and therapy applications was designed using bisphosphonate/carboxylic ligands.
Tripolyphosphate as precursor for REPO4: Eu3+ (RE = Y, La, Gd) by a polymeric method
A modification of the Pechini method was applied to obtain luminescent rare earth orthophosphates. The developed synthetic route is based on the ability of the tripolyphosphate anion (P3O105-) to act both as a complexing agent and as an orthophosphate precursor. Heating of aqueous solutions containing RE3+, Eu3+, P3O105-, citric acid, and ethylene ...
Growth and Melting of Metallic Nanoclusters in Glass: A Review of Recent Investigations
The mechanisms of nucleation and growth and the solid-to-liquid transition of metallic nanoclusters embedded in sodium borate glass were recently studied in situ via small-angle X-ray scattering (SAXS) and wide-an-le X-ray scattering (WAXS). SAXS results indicate that, under isothermal annealing conditions, the formation and growth of Bi or Ag nano...
