The predominant factors that significantly determine the end Au nanoparticle size is both the thiol group concentration and subjecting the as-made materials to an additional concentrated sulfuric acid extraction step.
Tensile test revealed that the increasing methyl group concentration made the PUEs be soften and weaken.
For example, ammonium persulfate selectively increases the carboxylic acid group concentration.
However, the latter potentially offer higher reactive group concentration thanks to the reactive anhydride groups.
The results are discussed in relation to the adsorbent pore structure and functional group concentration, adsorptive structure and adsorption mechanism.
Hereby, the high photocatalytic activities of CDs could be produced by enhancing carbonyl group concentration on their surface.
The third group also received 53 nm particles, but at a lower concentration corresponding to the same surface area as the group receiving 180 nm particles (the 53 nm surface area group, concentration 0.029 g/L).
The impurity level, surface functional group concentration, and specific surface area of activated carbons (ACs) are manipulated via acid rinsing, post heat treatment, and activation time, respectively.
Characterization of the modified activated carbon shows that it is possible to generate a large range in acidic group concentration without significant change of the textural properties.
Since the FIA method measures amide group concentration, the linearity of response for a series of partially hydrolysed polyacrylamides was measured.
Methacrylates and acrylates containing different number and types of ether groups were selected to determine the effects of ether group concentration and structure on oxygen inhibition.
