Chemical and physical effects of ultrasound: sonoluminescence and materials
… spray pyrolysis (USP) is used to prepare porous carbon spheres using energetic alkali propiolates as the carbon precursors. In this synthesis, metal salts are generated in situ, introducing porous structures into the carbon spheres. When different alkali salts or their mixtures are used as the …

Some aspects of combustion of coal in fluidized beds
… study of the mechanism of combustion of carbon in shallow fluidized bed combustors. Burning rates and temp eratures of electrode carbon spheres and burn -out times of hatch charges of char particles were measured experimentally over a wider range of variables than reported hitherto. Bed …

A Comprehensive Evaluation of Off-Gas Emissions From A Catalyst-Aided, Amine-Based, Post Combustion Capture of CO2 From Industrial Exhaust Gas Streams
… two solid basic absorber catalysts; Activated Carbon Spheres (ACS) and a proprietary absorber catalyst (APC) and one solid acid desorber catalyst, a proprietary desorber catalyst (DPC). The screening results for the absorber catalysts showed that the equilibrium loading, and initial absorption …

Microstructured materials synthesis via salt-assisted ultrasonic spray pyrolysis
… USP is used to make roughened ZnO microspheres. By controlling the amount of NaCl in the precursor solution, the agglomerated ZnO nanoparticles will form microspheres with varying degrees of roughness. The size of the particles formed is also easily controlled by adjusting the …
