Disordered carbons show a dislocated arrangement of C–H bonds which causes dislocations, vacancies, low-coordination sites, atoms with free valences, discontinuities, edges, and defects, called high-energy sites.

Pyrolyzed biomass-derived carbon is non-graphitizing, hard carbon with varying textures, morphologies, and degrees of crystallinity. It provides short diffusion paths for ionic and electron transport and can therefore be an attractive material for anodes in metal-ion batteries. The solid structure of ...
In the interest of finding effective and stable materials for optical limiting, we had tried to combine the multi-walled carbon nanotubes (CNTs) and ionic liquids surfactant (hydroxypropyl sulfo imidazoline) to obtain a new dispersion. Ultimately, we achieved non-covalent modification to carbon ...
In recent years, climate change has increasingly become one of the major challenges facing mankind today, seriously threatening the survival and sustainable development of mankind. Dramatically increasing carbon dioxide concentrations are thought to cause a severe greenhouse effect, leading to severe and s...
H-PHI shows values comparable to mpg-CN δ, obtained for the same mass of the material, which illustrates a transition from an ionic structure in Na-PHI to covalent as in mpg-CN upon substitution of Na+ with protons. Coupling of two benzylamine molecules is accompanied by the formation of...
Using your knowledge of how CO2 dissolves and reacts in water, explain why global increases in atmospheric CO2 should cause a decrease in the pH of ocean water. Is the reaction of calcium chloride with sodium carbonate ionic or covalent?

Of importance in determining the final structure and chemistry of the carbon is the presence of the non-carbon atoms: oxygen, hydrogen, and in many cases, nitrogen, phosphorus, or sulfur. In the case of the oxygen, the carbon/oxygen ratio factors heavily into the final structure. The C-O...
and stacking of the nanoparticles through a self-assembly process. Second, the charged nature of the ionic groups ensured the integrity of the IL–GF to produce a monolithic nanocomposite material. Thirdly, the assembly of IL groups on the surface of GFs increased the dispersibility of the ...
