A closed-form equation for predicting the hydraulic conductivity of unsaturated soils
- Van Genuchten, M. Th.
- Environmental Science
- 1 September 1980
A new and relatively simple equation for the soil-water content-pressure head curve, 8(h), is described in this paper. The particular form of the equation enables one to derive closedform analytical…

High Electron Mobility InN
Irradiation of InN films with 2MeV He+ ions followed by thermal annealing below 500°C creates films with high electron concentrations and mobilities, as well as strong photoluminescence. Calculations…
Excitonic behavior in self-assembled InAs/GaAs quantum rings in high magnetic fields

- 16 October 2009
We investigate the exciton energy level structure of a large ensemble of InAs/GaAs quantum rings by photoluminescence spectroscopy in magnetic fields up to 30 T for different excitation densities.…
Influence of electrolyte chemistry on the structure and reactivity of Fe(III) precipitates generated by Fe(0) electrocoagulation: Implications for low-cost arsenic treatment
- Van Genuchten, C. Michael
- Environmental Science
- 2013
The formation of Fe(III) (oxyhydr)oxide precipitates from Fe(II) oxidation and/or Fe(III) hydrolysis is a key process that often governs the fate and bioavailability of contaminants and nutrients in…
On the temporal and spatial variance in displacement velocity of a slide in varved clays in the French ALPS
- Van Genuchten, M. Pieter
- Geology
- 14 March 2007
The distribution of slide rate in time and space in an active landslide in varved clays in the French Alps are presented. Convergent flow of the sliding mass and increase of slide rate downslope…
Installing and optimizing the MOKE setup
- Van Genuchten, Hcm Eric
- Physics
- 2004
This report is about rebuilding and optimizing the signal to noise ratio (S:N) of the magnetooptical Kerr effect (MOKE) setup. The S:N is improved by successive steps of adjustments to the setup. The…
