چکیده
Amorphous glassy CaCO3 colloidal spheres of monomodal size distribution were studied by high-resolution Brillouin light scattering. The Young modulus of 37 GPa and shear modulus of 14 GPa of glassy CaCO3 at a density of 1.9 g/cm3 were extracted from the particle vibration frequencies by employing acoustic wave scattering cross-section calculations. The line shape of the low-frequency modes is a sensitive index of the particle polydispersity.

A systematic examination of the morphogenesis of calcium carbonate in the presence of a double-hydrophilic block copolymer.
In this paper, a systematic study of the influence of various experimental parameters on the morphology and size of CaCO3 crystals after room-temperature crystallization from water in the presence of poly(ethylene glycol)-block-poly(methacrylic acid) (PEG-b-PMAA) is presented. The pH of the solution, the block copolymer concentration, and the ratio [polymer]/[CaCO3] turned out to be important p...
متن کاملSynthesis and Characterization of Polyamide-66/Calcium Carbonate Composites
Polyamide-66(PA66)/CaCO3 micro- and nano-composites were prepared using a polymer solution method at filler loading of 0, 1, 2 and 3 weight percent. Nano-size of CaCO3 was synthesized by micro-emulsion technique. The material was characterized by XRD, SEM, FTIR and UV-VIS techniques. XRD results of composites suggested that CaCO3 particles are found in the amorphous phase of the semi-crystallin...
متن کاملColloidal carbon spheres and their core/shell structures with noble-metal nanoparticles.
Colloidal microand nanospheres have been of continuous research interest, since their intrinsic properties can be finely tuned by changing parameters such as diameter, chemical composition, bulk structure, and crystallinity. Up to now, they have found a broad range of applications in fields such as drug delivery, biodiagnostics, combinatorial synthesis, and photonic band-gap crystals (PBG). The...
متن کاملColloidal building blocks with potential for magnetically configurable photonic crystals
This contribution highlights some recent advances in the synthesis of monodispersed colloidal spheres loaded with superparamagnetic components for external manipulation. We firstly discuss how Fe3O4 nanoparticles can be directly coated with silica to form core–shell particles using a sol–gel approach. We then focus on the demonstration of new materials for such an application, with Pb and amorp...
متن کاملIncreasing the density melts ultrasoft colloidal glasses.
We use theory and simulations to investigate the existence of amorphous glassy states in ultrasoft colloids. We combine the hypernetted chain approximation with mode-coupling theory to study the dynamic phase diagram of soft repulsive spheres interacting with a Hertzian potential, focusing on low temperatures and large densities. At constant temperature, we find that an amorphous glassy state i...
