The optical and thermophysical parameters of starch films (obtained by extrusion) were determined in order to obtain input data for photothermal studies of water migration in such films. The optical spectra, sorption isotherm, and volume change were

Cathodoluminescence (CL) of Er 3+ -doped alkaline earth fluorides is investigated in order to elaborate a thermal probe with micrometer spatial resolution. The green luminescence of Er 3+ ions represents a good candidate for such a purpose since this

After demonstrating recently the possibilities of scanning photothermal radiometry for wear crack detection (Bodnar et al., J. Phys. IV, 4 (1994) 591–594), we now study its possibilities for dimensional characterization of these kinds of flaws. In

Whole blood is an inhomogeneous, thermally fragile liquid suspension. It was shown that photothermal radiometry yields meaningful results, but required irradiation level might disturb the sedimentation process. Despite the necessity for direct contac

The photopyroelectric method was used for measuring the thermal parameters of starch sheets as a function of water content and temperature. The thermal conductivity, thermal effusivity and volume specific heat are increasing with water content while

Some near-field experimental methods use laser excitation inducing thermal effects that are often neglected or incompletely estimated (1,2). We particularly investigate the case of a Scanning Tunneling Microscope (STM). The thermal response of the ti

The aim of this study was to determine the depth-dependent water migration profile in starch sheets using a photothermal method. It is found that the distribution of the absorbed water is exponential, depending markedly on the duration of contact bet

The photopyroelectric method in a non contact detection configuration is proposed to study water migration in starch sheets. This allows the exchange of humidity between the moist atmosphere and the starch sample during the experiment. The sensitivit

This paper summarises the results of research in our laboratory and of some previous publications in order to find complementary methods to establish the actual scheme of the luminogene centres responsible for the broad spectral bands of fluorescent

Among other emissions, the natural cinnabar presents, under cathodic excitation, a broad red band. Examining the spectral properties of the emitted intensity and of the radiative recombination probability between 4.2 and 300 K, an attempt is made to
