  abstract  = {Ziel dieser Arbeit ist die Untersuchung der Ionenbindung an Polymeren und Lipidmembranen in w{\"a}ssrigen L{\"o}sungen. Im ersten Teil dieser Arbeit wurde der Einfluss verschiedener anorganischer Salze und Polyelektrolyte auf die Struktur des Wassers mit Hilfe Isothermer Mikrotitrationskalorimetrie (ITC) erforscht. Die Verd{\"u}nnungsw{\"a}rme der Salze wurde als Maß f{\"u}r die F{\"a}higkeit der Ionen, die geordnete Struktur des Wassers zu stabilisieren oder zu zerst{\"o}ren, verwendet. Die Verd{\"u}nnungsw{\"a}rmen konnten auf Hofmeister Effekte zur{\"u}ckgef{\"u}hrt werden. Im Anschluss daran wurde die Bindung von Ca2+ an Natrium- Poly(acryls{\"a}ure) (NaPAA) untersucht. Mit Hilfe von ITC und einer Ca2+- selektiven Elektrode wurde die Reaktionsenthalpie und Bindungsisotherme gemessen. Es wurde gezeigt, dass die Binding von Ca2+ - Ionen an NaPAA stark endotherm und daher entropiegetrieben ist. Anschließend wurde die Bindung von Ca2+ an die eindimensionale Polymerkette mit der an ein Lipidvesikel mit denselben funktioniellen Gruppen verglichen. Es wurde beobachtet, dass die Ionenbindung \–wie auch im Fall des Polymers- endotherm ist. Ein Vergleich der Ca2+- Bindung an die Lipidmembran mit der an das Polymer konnte zeigen, dass das Ion schw{\"a}cher an die Membran bindet. Im Zusammenhang mit diesen Experimenten wurde auch beobachtet, dass Ca2+ nicht nur an geladene, sondern auch an zwitterionische Lipidvesikel bindet. Schließlich wurde die Wechselwirkung zweier Salze, KCl and NaCl, mit einem neutralen Polymergel, PNIPAAM, und dem geladenen Polymer PAA untersucht. Mit Hilfe von Kalorimetrie und einer kaliumselektiven Elektrode wurde beobachtet, dass die Ionen mit beiden Polymeren wechselwirken, unabh{\"a}ngig davon, ob diese Ladungen tragen, oder nicht.},

  abstract  = {Background. Despite considerable progress made in the past decade through salt iodization programs, over 2 billion people worldwide still have inadequate iodine intake, with devastating consequences for brain development and intellectual capacity. To optimize these programs with regard to salt iodine content, careful monitoring of salt iodine content is essential, but few methods are available to quantitatively measure iodine concentration in a simple, fast, and safe way. Objective. We have validated a newly developed device that quantitatively measures the content of potassium iodate in salt in a simple, safe, and rapid way. Methods. The linearity, determination and detection limit, and inter- and intra-assay variability of this colorimetric method were assessed and the method was compared with iodometric titration, using salt samples from several countries. Results. Linearity of analysis ranged from 5 to 75 mg/kg iodine, with I mg/kg being the determination limit; the intra- and interassay imprecision was 0.9\%, 0.5\%, and 0.7\% and 1.5\%, 1.7\%, and 2.5\% for salt samples with iodine contents of 17, 30, and 55 mg/kg, respectively; the interoperator imprecision for the same samples was 1.2\%, 4.9\%, and 4.7\%, respectively. Comparison with the iodometric method showed high agreement between the methods (R-2 = 0.978; limits of agreement, -10.5 to 10.0 mg/kg). Conclusions. The device offers a field- and user-friendly solution to quantifying potassium iodate salt content reliably. For countries that use potassium iodide in salt iodization programs, further validation is required.},

  abstract  = {In this thesis we investigate the evaporation behaviour of sessile droplets of aqueous saline solutions on planar inert and metallic surfaces and characterise the corrosion phenomenon for iron surfaces. First we study the evaporation behaviour of sessile salty droplets on inert surfaces for a wide range of salt concentrations, relative humidities, droplet sizes and contact angles. Our study reveals the range of validity of the well-accepted diffusion-controlled evaporation model and highlights the impact of salt concentration (surface tension) gradients driven Marangoni flows on the evaporation behaviour and the subsequent salty deposit patterns. Furthermore we study the spatial-temporal evolution of sessile droplets from saline solutions on metallic surfaces. In contrast to the simple, generally accepted Evans droplet model, we show that the corrosion spreads ahead of the macroscopic contact line with a peripheral film. The three-phase contact line is destabilized by surface tension gradients induced by ionic composition changes during the course of the corrosion process and migration of cations towards the droplet perimeter. Finally we investigate the corrosion behaviour under drying salty sessile droplets on metallic surfaces. The corrosion process, in particular the location of anodic and cathodic activities over the footprint droplet area is correlated to the spatial distribution of the salt inside the drying droplet.},

  abstract  = {Scaling agriculture to the globally rising population demands new approaches for future crop production such as multilayer and multitrophic indoor farming. Moreover, there is a current trend towards sustainable local solutions for aquaculture and saline agriculture. In this context, halophytes are becoming increasingly important for research and the food industry. As Salicornia europaea is a highly salt-tolerant obligate halophyte that can be used as a food crop, indoor cultivation with saline water is of particular interest. Therefore, finding a sustainable alternative to the use of seawater in non-coastal regions is crucial. Our goal was to determine whether natural brines, which are widely distributed and often available in inland areas, provide an alternative water source for the cultivation of saline organisms. This case study investigated the potential use of natural brines for the production of S. europaea. In the control group, which reflects the optimal growth conditions, fresh weight was increased, but there was no significant difference between the treatment groups comparing natural brines with artificial sea water. A similar pattern was observed for carotenoids and chlorophylls. Individual components showed significant differences. However, within treatments, there were mostly no changes. In summary, we showed that the influence of the different chloride concentrations was higher than the salt composition. Moreover, nutrient-enriched natural brine was demonstrated to be a suitable alternative for cultivation of S. europaea in terms of yield and nutritional quality. Thus, the present study provides the first evidence for the future potential of natural brine waters for the further development of aquaculture systems and saline agriculture in inland regions.},
