We present a theory that is able to account quantitatively for the surface and interfacial tensions of different electrolyte solutions. It is found that near the interface, ions can be separated into two classes: the kosmotropes and the chaotropes. While the kosmotropes remain hydrated near the interface and are repelled from it, the chaotropes loose their hydration sheath and become adsorbed t...

We present a new experimental system to observe reactions in biomembranes by combining laser spectroscopic techniques with phospholipid monolayers formed at oil/water interfaces. The system can monitor reactions through changes in interfacial tension at oil/water interfaces induced by the reactions under non-destructive and non-contact conditions. In addition, oil/water interfaces with defined ...

PANDA2, a computer program for the minimum-weight design of elastic perfect and imperfect stiffened cylindrical panels and shells under multiple sets of combined loads, is used to obtain optimum designs of uniformly axially compressed elastic internal T-ring and external T-stringer stiffened cylindrical shells with initial imperfections in the form of the general buckling mode. The optimum desi...
