DuPont E-120 high-modulus pitch-based carbon fibers were treated electrochemically in 0.5 M (NH 4 ) 2 CO 3 solution under both potentiostatic and galvanostatic modes. X-ray photoelectron spectroscopy (XPS) was used to monitor the chemical changes on the carbon fiber surfaces. Both core-level and valence-band spectra s…

Previous studies have shown that photoelectrochemical methods used to study the semiconducting properties of oxides may be extended to in situ investigations of thin oxide films. A new expression relating the photocurrent to the film thickness has been derived by combining a simplified Gärtner/Butler model and an opti…

A finite element method for the Cahn-Hilliard equation (a semilinear parabolic equation of fourth order) is analyzed, both in a spatially semidiscrete case and in a completely discrete case based on the backward Euler method. Error bounds of optimal order over a finite time interval are obtained for solutions with smo…

Many of the methods for measuring beer foam are based on measurements of the weight or volume of beer collapsed from foam rather than on measurements of the foam itself. However, these drainage methods may not reflect the consumer's perception of foam collapse. Therefore, a method to characterize numerous properties o…
