For the first time, the thermal diffusivity (α) in red clay samples has been determined as a function of the annealing time, for a furnace temperature above 900 ◦ C. The thermal diffusivity measurements on the samples were obtained by means of the

The optical absorption centres in corn pericarp biopolymers have been studied by photoacoustic spectroscopy and the phase-resolved technique. The results show that the optical absorption spectra of these samples are formed by the superposition of two
