Ion mixing of metal/Al bilayers near 77 K

Near-threshold K+ production in heavy-ion collisions.

Within a hadronic transport model we study in detail contributions to kaon yields and momentum spectra from various baryon (resonance)-baryon (resonance) and πN interactions in heavy-ion collisions at beam energies near the free-space kaon production threshold. It is found that the finite lifetime of baryon resonances affects significantly the shape of kaon spectra, and the high energy parts of...

Ion-gated channel induced in planar bilayers by incorporation of (Na+,K+)-ATPase.

An ion-gated channel was conferred on a planar lipid bilayer membrane upon incorporation of (Na+,K+)-ATPase. The channel exhibited two conductance states. The high conductance state was only observed when an ion gradient was present across the planar membrane. This state corresponded to an enzyme conformation which was ouabain and vanadate sensitive (i.e. conductance was inhibited by these comp...

an experimental study of turbulent mixing near a density interface

the entrainment of a stably stratified layer into a turbulent mixed layer in a confined region has been studied in the laboratory for different richardson numbers, ri. the results include direct observation of turbulent characteristics and density measurements using two high precision salinity meters. the measurements include turbulence intensity, scale of eddies near the interface and energy s...

Tracking an ion complexing agent within bilayers

Bright ion channels and lipid bilayers.

If we look at a simple organism such as a zebrafish under a microscope, we would see many cells working in harmony. If we zoomed in, we would observe each unit performing its own tasks in a special aqueous environment isolated from the other units by a lipid bilayer approximately 5 nm thick. These confined units are social: they communicate with one another by sensing and responding to the chem...
