Black Carbon and the Carbon Cycle
Science, 1998When vegetation and fossil fuels burn, the combustion creates "black carbon" that becomes distributed throughout the environment. Determining how it is created and where it goes is important for studying the past history of fire and for understanding global carbon and oxygen budgets.

Journal of Geophysical Research: Atmospheres, 1996
Hydration studies of n‐hexane soot particles in the relative H2O pressure range 0.33–0.52 have revealed the nature of the processes between water molecules in the vapor phase and primary reaction sites at the particle surface. Initially, about 40% of the carbon‐oxygen functionalities (most likely the carboxylics) on freshly prepared soot reacts ...

Carbon, 1979
Abstract The kinetics of the fluorination of carbon black and the properties of the graphite fluoride prepared are discussed in comparison with those of graphite and petroleum coke. An appreciable weight increase is observed in the fluorination of carbon black even at room temperature because of the large surface area.

MRS Proceedings, 2000
ABSTRACTX-ray diffraction, Raman spectroscopy, and neutron scattering were used to characterize structure of carbon blacks. Different grades, N990, N774, N299, N134, and N110, untreated, after heat treatment and compressed at 2.5 GPa have been investigated.

A comparison of carbon black with soot
Science of The Total Environment, 1983Carbon black is frequently confused with soot. In order to clarify the distinction between these materials, we have examined 6 carbon blacks and 18 samples of soot. Carbon black is composed of turbostratic colloidal aggregates which we call aciniform carbon (AC).

Carbon black porosity. II. Selection of t-values for carbon blacks
Journal of Colloid and Interface Science, 1976Abstract The relative merits of t-values proposed by Pierce, Lippens, and Smith and Kasten for measuring porosity values of both fluffy and pelletized carbon blacks are discussed. A set of t-values based upon adsorption data for fluffy blacks varying in particle size from MT to ISAF is proposed for measuring carbon black porosity values.

The Electrochemistry of Black Carbons
Angewandte Chemie International Edition in English, 1983Abstract“Modifications” of carbon—as long as they predominantly have the layered graphite structure—exhibit the following properties: (1) electrical conductance, (2) the ability to accomodate ions or molecules between the layers of the lattice, and (3) the ability to reactviafunctional groups at their surfaces (largely at the layer edges). The first of

Reinforcement of elastomers by carbon black
Rubber Chemistry and Technology, 1977Abstract The reinforcement of elastomers by carbon black is governed by the morphology of the black and its physical and chemical interactions with the polymer. The latter are strongly affected by graphitization and surface oxidation. In modern rubber-grade carbon blacks strong bonding of the polymer to the carbon black surface is effected by ...

Australian Journal of Chemistry, 1959
The varying ability of carbons to oxidize FeII, to produce H2O2 when exposed to air in an acid medium, and to form a latent photographic image, has been studied on a graded set of carbon blacks. Mechanisms are discussed for these three types of activity and it is shown how they agree with the phenol-lactone-chromene concept of carbon black chemistry.
