摘要: Abstract The acoustic absorption of sonicated and unsonicated suspensions dipalmitoyl phosphatidylcholine has been studied as a function temperature at frequencies between 0.6 4.0 MHz. fixed frequency passes through maximum which is dependent on the sample preparation history somewhat observation, with vesicles exhibiting 2–3°C below that found for dispersions. dependence suggests cooperative process while indicates more than single relaxation time required to describe absorption.
