While the two classes of compounds share many structural features, including an abundance of carboxy, hydroxy, phenolic, and ketonic groups, FA has a lower molecular weight, a higher functional group density, and higher acidity than HA.
Dendrimers are highly branched supramolecular structures having high functional group density at nanoscale dimensions.
Petal-like ferric oxide/cysteine (FeOOH/Cys) architectures were prepared through a solvothermal route, which possessed high thiol group density.
SRHA: this is an aquatic HA with a relatively high functional group density.
Building on past work in this field [ 5], new cheap, easily synthesizable surfactants, bearing high methyl group densities in the chain-tip region have been studied as novel CO2-philes.
SAP materials of very high anionic functional group density take up the liquid quickly and release it back into solution (to a large extent) over the first one to 3 h.
A study in the USA 11 also showed the benefits of living in a higher own-ethnic group density neighbourhood for the emotional well-being of black and Hispanic groups.
We propose that ionic liquids optimized as CO2 carriers for facilitated transport membranes under humid conditions should have high amino-group density, which could be realized by decreasing the molecular size and introducing more amino groups in the molecule.
There was a broad pattern of more racism reported in schools and neighbourhoods with low than high own-group density.
In both datasets, the cluster we extracted had a significantly higher within-group density of interactions than what would be expected by chance (not shown), supporting our observations above.
