AbstractWe report the observation of strongly anisotropic scattering of laser light at oblique incidence on (100)-oriented porous silicon layers. We performed angle-resolved light scattering measurements and three concentric rings were observed. Modeling porous silicon by means of nanometric columnar air pores and an effective anisotropic uniaxial dielectric constant explains the observed phenomenon, and besides, the observation of the angle aperture of these rings allows a direct measurement of relative birefringence. We finally study the changes of optical anisotropy after different modifications of the structure.

In solution calorimetry, the choice of solvent is important. Some criteria for this choice for oxide melt solution calorimetry are reviewed. A new solvent is proposed and the corresponding physicochemical study is presented. Some structural interpretations are suggested for these Bi2O3–B2O3 melts. Keywords: thermochemistry, calorimetry, high temperature, oxide melt.
