CHEMISTRY: Does Saltwater Wobble?

Saltwater icephobicity: Influence of surface chemistry on saltwater icing

Most studies on icephobicity focus on ice formation with pure water. This manuscript presents studies to understand the influence of surfaces on saltwater ice nucleation and propagation. Experiments are conducted to quantify the influence of surface chemistry on saltwater ice nucleation and to understand the utility of superhydrophobic surfaces for saltwater icephobicity. These experiments are ...

Does sea-level rise have an impact on saltwater intrusion?

Clemen Climate change effects are expected to substantially raise the average sea level. It is widely assumed that this raise will have a severe adverse impact on saltwater intrusion processes in coastal aquifers. In th...

Accuracy in clinical chemistry--does anybody care?

The role of clinical chemistry in the diagnostic process has been enhanced by the evolution of better instrumentation and analytical techniques. The quality of some laboratory tests, however, has not kept pace with these advances. I present three examples--serum iron, serum lipase, and nonisotopic immunoassays--assays where some currently used methodologies are highly flawed. Causes for the les...

A variable height "wobble board".

The "wobble board" has been used for many years for the re-education of the musculature of the ankle and foot after injury. Varying heights of board have been used depending on the range of movement required at various stages of recovery but I have not seen, nor have some experienced colleagues seen, one where the height is adjustable. Such a device is here illustrated. It consists of a circula...
