A fractional (or stretched) time exponential, F(1) = exp[ -(t/F)"], where O<cr< 1, T a time constant, is proposed as the modulation function for vibrational band-narrowing in locally structured, amorphous media. It leads to physically sounder modulation times than current, pure exponential models, y
Seven fractions of a coal tar pitch having different molecular weights were carbonized up to 650Β°C under a pressure of 30 MPa in closed and open gold tubes. Carbon yield and microscopic texture of the resultant products were investigated. The graphitizability was evaluated through measurements of in
