The contributions that make up the main body of the text cover a variety of subjects, including mass transfer modeling into disk spaces of heat turbomachines, molecular dynamics simulation of lubricant depletion instability under laser heating, diffusion flame stability of low calorific fuels, and others.

According to David Haugen of EPA's Lab, high rates of oxidizing nitrogen are avoided by managing oxidation of fuel in the diffusion flame region.
Flame inhibition measurements are less frequently made on diffusion flames, due to the difficulty in defining a fundamental flame strength parameter such as burning velocity and also the strong geometrical influences on diffusion flame propagation.
Fundamentals: Proton affinities and metal-ion affinities of important species are determined in a number of ways and in comparison with those obtained using molecular orbital calculations: small inorganic and organic molecules (Bohme and Hopkinson), oxides and hydroxides produced in a hydrogen diffusion flame (Goodings and Hopkinson), and amino acids and peptides (Fournier, Hopkinson and Siu).
