In this work, a film flow model is developed to describe free water transport in a network of parallel capillaries. This model is inserted in a numerical drying code to simulate the longitudinal free water transfer during drying of oak wood. Convecti

PTFE deposited by friction at 300°C is known to align crystals. We have used infrared modulation linear dichroism (MLD) and polarization modulation infrared reflection absorption spectroscopy (PMIRRAS) to study the PTFE layer itself and coated with

Structural alterations induced by a thermal poling treatment which is at the origin of second harmonic generation in a Herasil silica glass are studied by x-ray absorption near-edge spectroscopy (XANES). Multiple scattering calculations are performed

Segmental orientation in uniaxially stretched poly(dimethylsiloxane) (PDMS) elastomeric networks is investigated by Fourier transform infrared dichroism. Precise determination of the dichroic effects, in the mid- as well as in the near-infrared range

Carbon preforms and C/C composites were treated with a H3PO4 aqueous solution in order to lower their oxidation rate. H3PO4 groups are adsorbed on carbon at room temperature. Rising the temperature results in the decomposition of the adsorbates and t

The purpose of this brief communication is to demonstrate how near-infra-red (n.i.r.) spectroscopy can be used to characterize molecular orientation in stretched polymers. Combined with the polarization modulation technique, n.i.r. provides a useful
