Alignment of hollow microspheres
Journal of Applied Mechanics and Technical Physics, 1991Currently there is considerable interest in the problem of creating hollow microspheres of uniform thickness made of amorphous materials of the glass, plastic, and polymer types. In the first instance this is connected with question of microencapsulation [I], and also development of new areas for the application of microspheres: laser thermonuclear ...

Photons confined in hollow microspheres
Applied Physics Letters, 2001Incorporation of CdSe quantum dots into a thin (<1 μm) surface shell of polymer microspheres (R∼2–4 μm) is achieved. The room-temperature emission spectra of single, hollow microcavities show several, spectrally well-separated cavity modes in the red-orange spectral range which have been assigned to high-Q whispering gallery modes (WGM) with ...

Physica E: Low-dimensional Systems and Nanostructures, 2006
Abstract Large scale metallic Zn microspheres and hollow ZnO microspheres are synthesized by thermal evaporation and vapor transport by heating a ZnO/graphite mixture at 1000 °C. Firstly, metallic Zn microspheres are fabricated with diameters in the range of 1–10 μm.

Synthetic hollow aluminophosphate microspheres**
Advanced Materials, 1995Hollow aluminophosphate microspheres, based on mesolamellar surfactant bilayer aluminophosphate composite material, have been synthesized in polyethylene glycol by an alkylamine surfactant based method. The surface of the spheres displays patterns of surface impressions as well as fine morphological detail withi the spherical features.

Hollow silica microspheres as robust immobilization carriers
Bioorganic Chemistry, 2019Hollow silica microspheres provide an ideal solid support for enzyme immobilization. We tested one of the newest development, namely MATSPHERES®, a silica openwork material as a carrier for the covalent immobilization of enzymes used to synthesize bioactive compounds.

Structure of hollow polystyrene microspheres: An SEM study
Journal of Microencapsulation, 1989Hollow polystyrene microspheres have been prepared by a modified interfacial polymer deposition technique. The hollow microspheres were characterized using scanning electron microscopy. The effects of polymer concentration and the quantity of the internal phase material (methanol) used on the microsphere size and their wall thickness were studied ...

Interfacial synthesis of hollow microspheres of mesostructured silica
Chemical Communications, 2001Hollow microspheres with ordered mesoporous walls are synthesised under ambient conditions by a simple procedure involving dilution and neutralisation of an aqueous tetraethoxysilane/cetyltrimethylammonium bromide reaction mixture.

From ZnO Hollow Microspheres to Radical Nanorod Arrays
Journal of Nanoscience and Nanotechnology, 2012Nanstructured ZnO has exhibited attractive multifunction for various applications, however, the nanostructures are so sensitive to the fabrication conditions that it is not easy to control the produced morphology. In this paper, ZnO hollow microspheres and radical nanorod arrays were fabricated based on the controllable solution chemical reaction.
