Nanoindentation of carbon microspheres

International Journal of Materials Research, 2016
AbstractThe indentation behavior of carbon microspheres was examined. The indentation load was in the range of 50 μN to 500 μN for the carbon microspheres with a diameter of ∼5 μm, and 15 μN to 100 μN for the carbon microspheres with a diameter of 1 μm. For the same ratio of the maximum indentation depth to the diameter of the carbon microspheres, both

Carbon Microspheres as Supercapacitors

The Journal of Physical Chemistry C, 2011
Carbon microstructures fabricated by ultrasonic spray pyrolysis (USP) of aqueous precursors were tested as supercapacitors. USP carbons (USP-C) possess unique physicochemical characteristics, including substantial microporosity and high surface concentrations of oxygenated functional groups.

Boron-doped carbon microspheres

Materials Chemistry and Physics, 2009
Abstract: A chemical vapor deposition (CVD) procedure has been used for the synthesis of boron-doped carbon microspheres (CSMs) using BF3/MeOH as the boron source, and acetylene as the carbon source. The boron-doped carbon microsphere samples were characterized by transmission electron microscopy (TEM), Raman spectroscopy and laser ablation mass ...

Preparation of porous carbon microspheres

Journal of Applied Polymer Science, 2006
AbstractPorous carbon microspheres with good morphology, high yield, and controllable particle size were prepared from phenolic resin. The particle size and pore structure of the carbon microspheres were mainly inherited from their precursors, resol microspheres, which were made through curing emulsified resol in water at 120°C under saturated pressure.

Nanofibrous microspheres via emulsion gelation and carbonization

Chemical Communications, 2015
Nanofibrous hydrogel microspheres are formed by pH gelation in emulsion droplets, which can then be freeze-dried and carbonized to produce nanofibrous carbon microspheres, showing high performance as electrode materials for supercapacitors.

Facile functionalization of HTC-derived carbon microspheres

Chemical Communications, 2012
Surfaces of HTC-derived carbons were functionalized using dienophiles such as maleimide (MI), tetracyanoethylene (TCNE), and 4,5-dicyano-1,3-dithiol-2-one (DCDTO). DCDTO-functionalized carbons were then hydrolyzed to yield thiol-functionalized carbons, which were used to perform conjugate addition on the carbon surface.

Supercapacitive Properties of PEDOT and Carbon Colloidal Microspheres

ACS Applied Materials & Interfaces, 2009
The synthesis and characterization of a new PEDOT-carbon composite prepared using a microporous carbon template are described. The electrochemical behavior of this composite, as well as that of three other colloidal materials-PEDOT-silica, PEDOT, and microporous carbon particles-is investigated with respect to their suitability as electrode materials ...
