This validated approach is afterward used to investigate the effect of loading path and initial residual stress characteristics on the kinetics of relaxation and the stabilized profile for both cyclic softening and cyclic hardening materials.
They reached -180 MPa (equivalent to 1.28 bulk material yield stress) at the longitudinal direction and -125 MPa (equivalent to 0.9 bulk material yield stress) at the transversal direction.

After the freezing of the materials, adsorbent will adsorb water vapor, which can play the effect of atmospheric freeze drying.
The adsorbent absorbs the moisture under the condition of low temperature and normal pressure, which makes the materials dry.

Introduction Physical properties of systems nanoparticles intensively studied during the last decades because nanocomposite materials exhibiting unique conductive, dielectric, magnetic and optical properties due to quantum size effects.
Nanocomposite materials based on porous glasses are of particular interest in consequence with the fact that they can form systems of different dimensions and cluster topologies depending on the conditions of interaction of the filler material with the matrix [1].
Thus, the aim of the work is to study the influence of the interaction between the pores of the matrix and the filler particles on the infrared absorption and Raman scattering spectra of the nanocomposite under study Materials For the preparation of nanocomposites, samples of porous SiO2 glasses (with a pore diameter of 320 nm, porosity of 50%, 10x10x1 mm) obtained at the Wroclaw University of Science and Technology (Poland) were used.
