Cover: Quartz crystal microbalance with dissipation monitoring is used to probe the effect of salt concentration on the phase transition behavior of thermoresponsive surface‐grafted poly(N‐isopropylacryl‐amide) (PNIPAM) brushes brushes. The phase transition temperature of grafted polymer is found to decrease as the concentration of salt is increased. This depression in phase transition temperature is similar to that observed for free polymer and is attributed to unbinding of the water molecules from the PNIPAM by the presence of ions. Further details can be found in the article by Y. K. Jhon, R. R. Bhat, C. Jeong, O. J. Rojas, I. Szleifer, and J. Genzer * on page 697.
