Water-in-Trichloroethylene Emulsions Stabilized by Uniform Carbon Microspheres
Langmuir, 2011Uniform hard carbon spheres (HCS), synthesized by the hydrothermal decomposition of sucrose followed by pyrolysis, are effective at stabilizing water-in-trichloroethylene (TCE) emulsions. The irreversible adsorption of carbon particles at the TCE-water interface resulting in the formation of a monolayer around the water droplet in the emulsion phase is

Strings of polymer microspheres stabilized by oxidized carbon nanotubes
Journal of Colloid and Interface Science, 2014Oxidized carbon nanotubes (CNTOs) with hydrophilic oxygen-containing functional groups and hydrophobic conjugated structure are prepared by the oxidation of carbon nanotubes (CNTs). After the polymerization of styrene with CNTOs dispersed in aqueous phase, polystyrene (PS) microspheres with string-like structure are obtained. Thermogravimetic analysis (

Carbon Microspheres as Ball Bearings in Aqueous-Based Lubrication
ACS Applied Materials & Interfaces, 2011We present an exploratory study on a suspension of uniform carbon microspheres as a new class of aqueous-based lubricants. The surfactant-functionalized carbon microspheres (∼0.1 wt %) employ a rolling mechanism similar to ball bearings to provide low friction coefficients (μ ≈ 0.03) and minimize surface wear in shear experiments between various ...

Dopamine-Induced Mineralization of Calcium Carbonate Vaterite Microspheres
Langmuir, 2010Two biogenic materials from mussels are attracting attention from scientists: calcium carbonate (CaCO(3)), the most widely studied biomineral that composes the shell, or nacre, of mussels, and dopamine, a small catechol-containing biomimetic molecule of adhesive foot proteins secreted by mussels.

Polymeric Microspheres Prepared by Spraying into Compressed Carbon Dioxide
Pharmaceutical Research, 1995The objective was to prepare polymeric microparticles by atomizing organic polymer solutions into a spray chamber containing compressed CO2 (PCA-process) and to study the influence of various process parameters on their morphological characteristics.The swelling of various pharmaceutically acceptable polymers [ethyl cellulose, poly(methyl methacrylate),

Hierarchical biomineralization of calcium carbonate regulated by silk microspheres
Acta Biomaterialia, 2013As an analog of the main protein contained in nacre regenerated Bombyx mori silk fibroin has a significant influence on the morphology and polymorphic nature of CaCO3 in the biomineralization process. A number of studies have implied that the self-assembling aggregate structure of silk fibroin is a key factor in controlling CaCO3 aggregation.
