Noncoding RNAs form unique 3D structures, which perform many regulatory functions. To understand how RNAs fold uniquely despite a small number of tertiary interaction motifs, we mutated the major tertiary interactions in a group I ribozyme by single-base substitutions. The resulting perturbations to the folding energy landscape were measured using SAXS, ribozyme activity, hydroxyl radical footprinting,...
We study the effect of adding trimethylsilyl-treated polysilicate nanoparticles (Rg∼2.2nm) to crosslinked poly(dimethylsiloxane) (PDMS) elastomers above the entanglement molecular weight. The results are compared to un-crosslinked PDMS of a similar molecular weight, reported in previous studies and filled with the same polysilicate nanoparticles.Three techniques are used and compared to assess the...
It is shown that positron annihilation parameters such as the average positron lifetime τ av and the ortho-positronium intensity I 3 respond to chemical inhomogeneities in disperse blends and their disappearance due to mutual diffusion of molecules of both phases, when Ps formation is inhibited by one of the constituents. This effect can be used to study mixing in initially demixed...
