Because of an ever-increasing demand of non-toxic, biodegradable, naturally-sourced materials and products, the human society is always searching for new materials with specific applications, which are able to fulfil the above-mentioned requirements. Consequently, it is essential to identify the qualities of these materials and their behaviour when subjected to various external factors, in order to find their optimal solutions for application in various domains. Such a material, obtained from renewable resources, is known as “liquid wood”, a material which exhibits composite polymer-like properties, having a lignin matrix. “Liquid wood” can be found in three different forms: Arboform, Arbofill and Arboblend, depending on the natural substances (besides or associated with lignin), which are to be found in the material – resins, wax, vegetable fibres etc. As such, “liquid wood” has been subjected to various external factors, the aim being to determine the degradation of the material when acted upon by environmental factors. Thus, “liquid wood” has been immersed in distilled water and then in an alkaline environment and in an acid environment for 210 days. Measurements were periodically performed to determine the mass variation and the change of electrical properties when subjected to the specific environmental factors and to UV radiation. The changes were determined by comparison with standard samples. Following this study, it has been observed that the main degradation factor is water, which leads to cracking and then fracture in the material. Furthermore, significant changes have been observed in the electrical properties of the material and in the pH of the environments in which it has been immersed. These observations lead to the idea that the material is hydrophilic. The results obtained following the immersion of “liquid wood” in distilled water and then in an alkaline environment and in an acid environment point towards some of the possible application of this material in various fields of activity, which may have a significant positive impact upon the environment.

Possible implications and consequences of using SL(2R) as invariance groups in the description at any scale resolution of the dynamics of any complex system are analyzed. From this perspective and based on Jaynes’ remark (any circumstance left unspecified in the description of any complex system dynamics has the concrete expression in the existence of an invariance group), in the present paper one specifies such unspecified circumstances that result directly from the consideration of the canonical formalism induced by the SL(2R) as invariance group. It follows that both the Hamiltonian function and the Guassian distribution acquire the status of invariant group functions, the parameters that define the Hamiltonian acquire statistical significances based on a principle of maximizing informational energy, the class of statistical hypotheses specific to Gaussians of the same average acts as transitivity manifolds of the group (transitivity manifolds which can be correlated with the multifractal-non-multifractal scale transitions), joint invariant functions induced through SL(2R) groups isomorphism (the SL(2R) variables group, and the SL(2R) parameters group, etc.). For an ensemble of oscillators of the same frequency, the unspecified circumstances return to the ignorance of the amplitude and phase of each of the oscillators, which forces the recourse to a statistical ensemble traversed by the transformations of the Barbilian-type group. Finally, the model is validated based on numerical simulations and experimental results that refer to transient phenomena in ablation plasmas. The novelty of our model resides in the fact that fractalization through stochasticization is imposed through group invariance, situation in which the group’s transitivity manifolds can be correlated with the scale resolution.
