• ], irradiated [46], metal–semiconductor couples [42][47], etc.) can be thermally characterized to determine thermophysical properties, such as the thermal diffusivity and thermal effusivity. At lower frequencies, the measurements are subject to 3D effects and necessitate a change in the laser beam shape. At low

• originating from chemical initiators [6]. The interest in measuring the thermal conductivity (k) and the thermal effusivity (e) of nanofluids containing semiconductors has increased [15] because of their increasing use in devices [16]. The photoacoustic (PA) effect has been demonstrated to be a valid

• –PVA at 50 kGy. In order to calibrate the set-up, the thermal effusivity of distilled water and ethylene glycol were measured and found to be 0.160 and 0.082 (W·s1/2·cm−2·K−1), which perfectly agreed with the reported values of the literature [32][33][34]. The thermal effusivity of distilled water, PVA
