Sentence examples for by oxygenated functional groups from inspiring English sources

Open image in new window Fig. 5 Compositions of light oil and heavy oil categorized by oxygenated functional groups.

So, the possible mechanism involves the initial physisorption of H2S molecules by oxygenated functional groups on the graphene surface (Fig. 6a) which later reach to the finely dispersed active CuO nanoparticles and get chemisorbed through reactive adsorption and converted into CuS (Fig. 6b) [49].

The incorporation of nitrogen into the graphene lattice by substitution of oxygenated functional groups is demonstrated outlining the validity of this approach for further functionalisation.

Reasons explaining such trends have been discussed considering the different effects that may impact the soot formation (i.e. the chemical effect induced by the presence of oxygenated functional groups in the fuel mixtures and the dilution of the base fuel by the additives which remains the most important factor for all the considered molecules).

These properties are changed by the addition of oxygenated functional groups (i.e., carbonyl, carboxyl, hydroxyl, etc).

The fast proton transfer comes from the hydrogen-bonding networks formed by the interaction between the oxygenated functional groups and water molecules.

GO is characterized by a high degree of oxygenated functional groups: carbonyl, carboxylate, and hydroxyl.

This method has been found to be capable of producing a large amount of 4(20), 11(12 -taxadienes with C-12 -taxadienesfunctional groups rather than with C-14 oxygenated functional groups [ 21].

However, GO is an electrically nonconductive material; thus, the oxygenated functional groups must be removed either by reacting with chemical agents to form chemically reduced graphene or heating in a furnace to yield thermally reduced graphene (TRG)[10, 11, 14, 15].

The preoxidized 8-h-xanthated coal prepared in this work showed a better Cd2+ removal (81%% against 15%%) than a non-preoxidized 40-h-xanthated coal, which suggests that the oxidation of coal increases the amount of oxygenated functional groups in the coal structure; this oxygenation enhance the extent of xanthation and increase the density of exchangers in the coal surface.

Various types of oxygenated functional groups on the biochar were quantified by means of titrimetric techniques using a modified Boehm's method.
