Patterning of micro- and nanometer scale structures by means of nanostencils (shadow masks) is increasingly being used as a simple, clean and low-cost alternative to photolithography. It can be shown, that sub-100-nm scale features can be fabricated throug ...
A combined simulation of runoff dynamics and distributed transport of the stable isotope oxygen-18 (18O) was performed in the mountainous Dreisam basin (258 km2) in the southwest of Germany. For this purpose, a mixing cell solute routing scheme was impleme ...
The study was performed in the Sahelian part of Burkina Faso. The country is subject to difficult climatic conditions, a strong demographic growth and a continuous decrease in soil fertility. The resulting degradation affects the processes which govern eco ...
This paper aims at a first theoretical step toward the probabilistic modeling of nutrient contents in catchment-scale soil states. To this end, we wish to characterize probabilistically the slow, leaching-prone component of the hydrologic response, which c ...
Superparamagnetic MnFe2O4 nanocrystals of different sizes were synthesized in high-boiling ether solvent and transferred into water using three different approaches. First, we applied a ligand exchange in order to form a water soluble polymer shell. Second ...
Ozonation of natural surface water increases the concentration of oxygen-containing low molecular weight compounds. Many of these compounds support microbiological growth and as such are termed assimilable organic carbon (AOC). Phytoplankton can contribute ...
In this paper, the second of a series, we apply the models discussed in Part 1 to a significant case study. The nature of the catchment under study, the transport phenomena investigated (i.e. nitrates moving as solutes within runoff waters) and the scales ...
We investigated the interactions of dissolved reactive phosphorus (DRP) and dissolved nonreactive phosphorus (DNRP) with suspended and settled aquatic particles. The sorption to minerogenic particles from an alpine catchment collected in rivers, hydropower ...
A novel chem. has been developed for the prodn. of capsules composed of a hydrophobic liq. core surrounded by a cross-linked polyacrylamide/alginate membrane. These liq.-core capsules may be used in capsular perstraction for the removal of inhibitory produ ...
Interaction of liquid crystals with nanostructured surfaces is studied experimentally. Whereas photolithographic or ATM methods mere used in the past for surface structuring, we use besides photolithography essentially replication methods for the creation ...
