Conformationally constrained nucleotides have a stabilizing effect on RNA/DNA duplexes. In their Communication on page 11242 ff., S. Hanessian, P. P. Seth, et al. present a doubly constrained tricyclic nucleotide (α-L-TriNA) that imparts great duplex stability.
A general method for the design of colloidal analogues of polymer chains with tunable flexibility from dielectric colloids is described by H. R. Vutukuri, A. van Blaaderen, et al. in their Communication on page 11249 ff.
In their Communication on page 11350 ff., M. O. Wolf et al. study the formation of amine-capped Pd nanoparticles by NMR analysis, and show that these species can be produced at lower temperature in the presence of a Lewis base.
