11. Vibrational Sum Frequency Spectroscopy Studies at the Air-Liquid Interface
Sammanfattning : In this thesis the structure and hydration of small organic and amphipilic compounds adsorbed at the air-liquid interface, have been studied using the nonlinear optical technique Vibrational Sum Frequency Spectroscopy (VSFS). The second order nature of the sum frequency process makes this technique particularly surface sensitive and very suitable for interfacial studies, as molecules at the surface can be distinguished even in the presence of a vast excess of the same molecules in the bulk.

12. Development and improvement of methods for characterization of HPLC stationary phases
Sammanfattning : High Performance Liquid Chromatography (HPLC) is a widely used tech-nique both for detecting and purifying substances in academy and in the industry. In order to facilitate the use of, and knowledge in HPLC, character-ization of stationary phases is of utmost importance. LÄS MER
13. Interactions between non-polar surfaces in water: Fokus on talc, pitch and surface roughness effects
Sammanfattning : The aim of this thesis work was to gain understanding of the interactions between talc mineral and surfaces, liquids and chemicals relevant for industrial applications, such as pulp and paper. Talc is used in the pulp and paper industry as a filler pigment, in control of pitch (lipophilic extractives) deposits and as a coating pigment. LÄS MER
14. Removal of Inorganic Anionic Pollutants from Water using Adsorption Technology
Sammanfattning : In the era of urbanization, industrialization and population growth, groundwater and drinking water sources are getting adversely polluted due to the addition of different toxic contaminants including inorganic anionic pollutants. The inorganic anions are of serious concern due to their adverse health effects on humans, even when present at very low concentrations in water. LÄS MER
15. Adsorption of polyhydroxyl based surfactants
Sammanfattning : Adsorption on solid surfaces from solution is a fundamental property of a surfactant. It might even be the most important aspect of surfactant behavior, since it influences many applications, such as cleaning, detergency, dispersion, separation, flotation, and lubrication. LÄS MER
