Carbon nanostructures were prepared by RF magnetron sputtering at deposition times from 30 to 120 min and temperatures on silicon substrates from 390 degrees C to 510 degrees C. Scanning and transmission electron microscopy ...

Carbon fiber reinforced carbon composites can be made by iterative liquid impregnation or gas phase carbon deposition routes. In both cases, at the final processing stage the carbon fiber is embedded in carbon matrix which ...

Mineral carbonation has enormous potential for carbon capture and storage (CCS). CO2 is a greenhouse gas that can be converted into environmentally stable products through mineral carbonation, which has been pointed out ...

This work presents a surface study of monolithic vitreous (or glassy) carbon - MVC - obtained from vitreous carbon powder. Defective MVC pieces are crushed in a ball mill and size classified by sifting. The MVC powder is ...

In recent years, reinforcements consisting of carbon nanostructures, such as carbon nanotubes, fullerenes, graphenes, and carbon nanofibers have received significant attention due mainly to their chemical inertness and ...

This paper presents the preparation and characterization of carbon fiber felt and activated carbon fiber felt from textile polyacrylonitrile fiber. Carbon fibers are usually related to aircraft manufacturing or high ...

The present study reports the simultaneous determination of dipyrone and codeine by a simple, fast and low-cost method using carbon black paste electrode (CBPE) modified with α-cyclodextrin (CD) and hierarchical porous ...

The aim of this paper is to study the effects of carbonation on the electrochemical properties of carbon steel and galvanized steel, immersed into cubic prisms of concrete elaborated with Portland pozzolanic cement. ...
