Development of nonlinear 3-D, and novel 2-D optical microscope imaging systems for time-lapse imaging
(2004)The design and development of a nonlinear two-photon, 3-D microscope imaging system, software for manipulation of 2-D and 3-D images, and the operation of a novel 2-D imaging system used for monitoring cultured live cell ... -
Effects of ultra violet and visible light on bacterial survival / by Natasha Vermeulen.
(2006)The optical dose in mJ/cm[superscript]2 for causing mortality of Escherichia coli, using wavelengths between 230-375 nm in the UV and 400-532 nm in the mid-visible spectral regions, has been determined in this study. ... -
Hall effect investigations in n-InSb under pressure
(1978)Low field electrical transport properties of n-InSb in the temperature range 6.4K-300K have been studied under pressures up to 15 kbar using Hall measurements. The pressure dependence of the carrier concentration, the ... -
Hydrostatic pressure effect on the Gunn threshold electric effect in n-InSb
(1978)The Gunn effect as a function of pressure has been studied in n~type InSb. The Gunn threshold field is found to decrease with increasing pressure reaching a minimum at P ~ 9 kbars. It then increases while the oscillations ... -
Optical determination of metal-semiconductor Schottky barriers
(1982)The photovoltage produced by a Schottky barrier photocell shows a strong temperature dependence if the barrier is not too large. We have used this temperature dependence to obtain the barrier height for several ... -
Photoluminescence and raman characterization of PLEE and MBE grown semiconductor epilayers
(1994)Photoluminescence and Raman investigations of selected alloy semiconductor epilayers are reported. Correlations relating optical spectra and a number of intrinsic and extrinsic properties of the materials studied are ... -
Pressure dependent extrinsic effects in InSb
(1980)Electrical transport properties of n and p-type InSb in the temperature range 6.2-300K have been studied under pressures up to 15 kbar using Hall measurements. The donor gap in n-InSb is found to increase linearly with ... -
Proton NMR spectral study of UV treated live Escherichia coli Bacteria / by Michael Sorokopud.
(2010)The lethal effects of ultraviolet radiation on microorganisms have been known and utilized for many years. In sufficiently high photon fluences, light and in particular, UV light, is an effective and subtle means of killing ...
