Despite the different structure, confirmed by Raman spectroscopy, both types of materials give apparent power law dependence of current with voltage and temperature and scaling of all measurements into a single universal curve.
Thus, it becomes apparent the convenience of combining both types of materials in such a way to explore the advantageous features of each of them.
The experimental results show that the sliding distance was the major parameter among other control factors on abrasive wear of both types of materials, followed by applied load for ADI's austempered at 180 min.
The strain distributions obtained from the three indenters tested were studied, in order to clarify the differences in the load indentation depth curves and hardness values of both types of materials.
XRD, XPS and UV vis results proved that in both types of materials Nb was present as +5 cation in a tetrahedral coordination involved in Nb O Si bonds and no extra framework niobium species were formed.
Although similar electrochemical data (HOMO: −5.43 eV, LUMO: ∼−3.15 eV, Egec= 2.28eV) as well as identical thin film absorption behaviour (λa=500 nm, Egopt= 2.10eV) were obtained for both types of materials, significant differences in their thin film photoluminescence behaviour and photovoltaic properties were observed.

By integrating graphene/poly vinyl alcohol) composites as the conductive sheath around yarn, and polyurethane yarn as the elastic core by using a layer-by-layer assembly method that is simple, scalable and low in cost, the merits of both types of materials are incorporated to fabricate sensors with enhanced performance.
Figure 8 shows the Raman spectra of both types of materials.
