Optical Characterization of Soot
Berichte der Bunsengesellschaft für physikalische Chemie, 1993AbstractThe chemistry of fuel‐rich hydrocarbon flames is extremely complex because different types of high molecular mass structures are produced. In fact, Polycyclic Aromatic Hydrocarbons (PAH) and submicronic turbostratic graphitic‐like particles (soot) are not the only products present but also partially aromatic polymers, gums, fullerenes and ...

Effect of soot shape on soot radiation
Journal of Quantitative Spectroscopy and Radiative Transfer, 1983Abstract It is increasingly recognized that soot particles play an important role in the radiative heat transfer from flames and smoke. After their formation, these minute particles usually conglomerate into different forms, with the limiting shapes being the spheres and long chains which can be modeled as infinite cylinders.

CASCON First Decade High Impact Papers on - CASCON '10, 2010
This paper presents Soot, a framework for optimizing Java* bytecode. The framework is implemented in Java and supports three intermediate representations for representing Java bytecode: Baf, a streamlined representation of bytecode which is simple to manipulate; Jimple, a typed 3-address intermediate representation suitable for optimization; and Grimp,

The Many Faces of Soot: Characterization of Soot Nanoparticles Produced by Engines
Angewandte Chemie - International Edition, 2014AbstractSoot nanoparticles produced by engines constitute a threat to human health. For the analytical chemist, soot is a hard nut to crack as the released particles undergo rapid changes in their size, shape, and number concentration. The complete characterization of soot will be essential to meet future low‐emission standards.

Science, 1982
A potential problem associated with soot particles in the atmosphere is pointed out, namely, the catalytic activity of such particles for certain atmospheric chemical reactions, including the oxidation of sulfur dioxide to sulfate. Conversion of SO/sub 2/ to sulfate is widely recognized as a major source of acidity in clouds and rain water.

On the rate of combustion of soot in a laminar soot flame
Combustion and Flame, 1962Abstract Rates of combustion of soot were measured in a laboratory type laminar hydrocarbon gas flame. The mass flow rates of soot were determined together with the local temperatures and the partial pressures of the oxygen at successive stages of the reaction.

Slicing is a powerful technique that can help a developer to understand how the interaction of different parts of a program causes a specific outcome. Dynamic slicing uses runtime information to compute a precise slice for a given execution. However, dynamic slicing is not possible without a static analysis of the underlying code to reveal dependencies

Effects of Soot Structure on Soot Oxidation Kinetics
2011Abstract : This project focused on the mechanisms of soot oxidation by O2. A two-stage burner was used. Soot was generated for ethylene, JP-8 surrogate (n-dodecane/m-xylene), m-xylene, and n-dodecane air premixed flames. Downstream, the soot-laden gases were passed through a secondary flat-flame burner where soot was burned out under fuel-lean or -rich

A mechanism for the formation of soot particles and soot deposits
Combustion and Flame, 1992The extent of the role of polycyclic aromatic hydrocarbon (PAH) species in the mechanism of soot formation has not definitely been determined. In previous work using a flat-flame, water-cooled, premixed burner burning ethylene-air flames we investigated the formation and destruction of PAH species up to five aromatic ring structures.

Soot From Fires: III. Soot Suppression
Journal of Fire Sciences, 1986The literature on soot suppression, in particular from fuels relevant to fires, has been reviewed. The efficient additives required for soot suppression from gaseous fuels are mainly metallic salts, typically barium. On the other hand, the reduction of the smoke formation tendency of polymeric materials has been achieved by an enormous variety of ...
