TL;DR: An improved approach composed of an oxidation reaction in acidic H2O2 solution and a sequential silanization reaction using neat silane reagents for surface modification of poly(dimethylsiloxane) (PDMS) substrates was developed, indicating that the PEG-grafted PDMS surfaces exhibit improved short-term surface dynamics and robust long-term stability.

TL;DR: In this article, the authors used ionization-induced injection to inject charge into the wake of relativistic plasma waves (the wake) over tens of vacuum diffraction lengths.

TL;DR: In this paper, the collapse of monolayers of 2-hydroxytetracosanoic acid at the air/water interface was examined by measurements of surface pressure−area isotherms and imaging with light scattering microscop...

TL;DR: In this paper, it was shown that rotaxanes are mechanically switchable in closely packed Langmuir films with chemical reagents and that mechanical switching has been proven to occur in bilayers while mounted on solid substrates, which not only constitute a proof of principle but also provide the impetus to develop solid state nanoelectromechanical systems that have the potential to reach up to the mesoscale.

TL;DR: The description, which is tested in a combined microscopy and rheology study of the collapse of a single-phase Langmuir monolayer (LM) of 2-hydroxy-tetracosanoic acid (2-OH TCA), provides a connection between the in-plane rheologies of LMs and reversible folding.
