The Influence of Agarose Concentration in Gels on the Electrophoretic Trapping of Circular DNA

January 1, 2003

Author(s)

Kenneth D. Cole, B. Akerman

The concentration of agarose in electrophoresis gels was found to have significant effects on the apparent density and release characteristics of the electrophoretic traps for circular DNA. Agarose gels were cast in a range of concentrations from 0.25% to

The Influence of Liquid Pool Temperature on the Critical Impact Weber Number for Splashing

January 1, 2003

Author(s)

Samuel L. Manzello, Jiann C. Yang

An experimental study is presented to determine the influence of liquid pool temperature on splashing behavior. Water droplets with initial diameter of 3.1 mm 0.1 mm impacted a water pool 40 mm in depth. The impaction process was recorded using a high

The Influence of Shearing Parameters on the Frictional Forces Measured Between Polymer Brushes

January 1, 2003

Author(s)

Aaron M. Forster, S. M. Kilbey

Polymer brushes have potential as end-tethered lubricants. Brush layers immersed in a good solvent must be compressed to ~16% of their equilibrium height before friction forces are measured. The same experiment in a solvent near the theta temperature will

The Information Depth and the Mean Escape Depth in Auger Electron Spectroscopy and X-Ray Photoelectron Spectroscopy
