However, progress in this area has been rather slow, and it remains difficult to elucidate their structure and behaviour at the molecular level.
Most glycodendrimers have to be considered highly flexible molecules with their conformational preferences most difficult to elucidate by experimental methods.
The driving forces behind these differences have been difficult to elucidate given the heterogeneity of previously compared cohorts.
It is difficult to elucidate the nanoparticle effect without eliminating this impurity effect.
However, the nanostructure density, in such samples, makes it difficult to elucidate the exact growth mechanism.
It is difficult to elucidate the nanoparticle effect without eliminating this impurity effect[5].
Multidrug resistance usually occurred either due to indiscriminate utilization of antimicrobial agents or genetic mutation, which was difficult to elucidate with the present study methodology.
First, the retrospective nature of this study makes it difficult to elucidate known confounders that could have biased the outcome measures, such as differences in sepsis treatment.
These cases are often extremely difficult to elucidate using (hbox {MS}^n) alone and the information from additional analysis such as NMR will usually be necessary.
We already knew, he claimed, that the notion of having evidence for a claim is very difficult to elucidate; Hempel's paradoxes succeeded in showing that.
At this time it is however difficult to elucidate a precise mechanism.
