To me, rather than being a "value add" ("bonus armor when you buy from us!"), it's a removal of functionality.
The second weight loss, in the temperature range 200 400 °C, is due to the removal oxygen functionalities.
X-ray photoelectron spectroscopy (XPS) analysis revealed the removal of oxygen functionality from the GO surface after reduction and the bonding structure of the reduced composites were further determined from FTIR and Raman spectroscopic analysis.
Measuring overlapped regions between different sheets leads to more realistic thickness values, which clearly reflect, for example, the removal of oxygen functionalities from graphene oxide following chemical reduction.
On the basis of the results, the ALR technique offers a great potential for accurately tune electrical and optical properties of carbon materials through the cyclic removal of oxygen functionalities, without any complicated thermal and chemical desorption processes.
The obtained data indicate the removal of oxygen functionalities and growth of the graphene domains on the GO surface that leads to the improvement of surface conductivity which is a growing function of the ion fluence.
Nevertheless, the studies on the oxidation mechanisms of Si NWs have been focused mostly on the formation of thick oxide layers at relatively high temperatures and long times, overlooking the early stages of oxidation which involve removal of surface functionalities and suboxides formation.
It is important to note that previous studies have investigated removal of key functionalities from the PKAc active site, albeit by mutagenesis, and also failed to completely abolish the enzyme's activity.
This material, in powder form, is highly soluble in water (approximately 2.1 mg/ml) due to the p-sulphonated substituents, and it is relatively free of basal plane defects that typically result from the removal of the oxygen functionality of comparable GO compounds.
