We investigated the effect of high power ultrasound, at a frequency of 19 kHz, on the survival of bacteria, phytoplankton and zooplankton, in order to obtain estimates of effective exposure times and energy densities that could be applied to design o

We investigated the disinfection of sewage and several bacterial pure cultures relevant to sewage using ultrasound produced by the magnetostrictive material, TERFENOL-D. Particular attention was paid to measuring the ultrasonic exposure time and ener

X-ray photoelectron spectroscopy (XPS) and atomic force microscopy (AFM) have been used to characterize the adsorption of alginic acid to titanium as a function of alginic acid solution pH. It was found that alginic acid adsorbs in greater quantity a

The Ebel Model, which characterizes a sample consisting of a thin carbonaceous overlayer on a substrate of a different material, provides a relationship between the carbon 1s and Auger peak intensities and the overlayer thickness. In this paper, Ebel

The objective of this work is to covalently attach bacteriorhodopsin (BR) to a gold surface via genetic substitution of cysteine for serine (S35C) at the 35th amino acid position. Samples of BR-containing purple membrane (PM) on gold were evaluated u
