Present paper deals with a novel approach on theoretical ionicity / basicity based on electronic energy levels or band structure of solids.
Though numerous authors have made extensive investigations on acid-base phenomena in aqueous and non-aqueous chemistry, very little has been done to determine acid-base relationships in solid materials, particularly in glass.
The concept of crystal ionicity has proved to be a useful unifying concept for understanding chemical trends in diverse problems in solid state physics and chemistry.
Levine's [10,11] modifications introduced for the calculation of (2) and (3) have improved the results obtained for various crystal structures.
Hence, it follows that ionicity depends directly on the amount of homopolar part and on value of Eg, where Eg can be obtained experimentally via spectroscopic methods or calculated using quantum chemistry techniques.

This mechanism was observed in the edge-to-face (T-shape) structure of hexafluorobenzene [5].
As is seen from the calculated band structure and density of states (DOS) (Fig. 6), the system shows the direct band gap of 3.21 eV, which demonstrates a significant effect of molecular functionalization by PFPh ligands on Si-PFPh electronic structure (cf.

By comparing solutions and films of the mixed components with solutions and films of the antioxidant placed between the dye and UV source, we can show that the effect is not UV screening but is due to some form of intermolecular chemistry.
We believe that this effect may account for the high stability of natural dyes in plant tissues, such as the skins of fruit, and may be usable to stabilize natural dyes in foods or textiles, especially if suitable nanoparticle structures can be developed.

The Research Landscape of Biorefinery: A Scientometrics Viewpoint Arnis Kokorevics Latvian State Institute of Wood Chemistry, Dzerbenes str. 27, Riga LV1006, Latvia arnis.kokorevics@kki.lv Keywords: biorefinery, research landscape, scientometrics, publications output, cooperation Abstract.
The scientometrics study of the publications set devoted to biorefinery allows to characterize the research field, its dynamics, most relevant countries, institutions, and authors, cooperation, thematic structure, and publishing praxis.
The keywords cooccurrence analysis allows recognition of 4 subfields of research: biorefinery itself and biofuels, wood chemistry, algae and biotechnology, and alcohol production.
It is interesting that biofuels, which are among the main proposed yields of biorefinery, are in the same cluster with biorefinery itself, while other yields/ products – form clusters named “Wood chemistry” and “Alcohol”.
