Reverse Microemulsion System In Compressed Co2: Phase Behavior and Applications For Cleaning Biomaterials
… is limited due to its low solvent capacity for polar substances, such as proteins and biomolecules. This limitation can be overcome by adding small amounts of suitable surfactants. The strategy is to create a water-in-CO2 microemulsion phase to enhance the water content in CO2, and make it …

Studies on pro-oxidant cytochrome P450 enzymes as drug discovery tools and the discovery that they also have a dual function as antioxidants
… particular CYPs metabolise medicines into more polar substances through such reactions as hydroxylation etc. Hence, CYPs are thought to function as pro-oxidants, allowing addition of oxygen to unreactive carbon atoms. However, CYPs also act as electron sinks, indicating that it may inherently …

Untersuchungen der elektrochemischen Eigenschaften pH-sensitiver Feststoffsensoren in unpolaren Flüssigkeiten
The area of electrochemistry of non aqueous non-polar liquids has not been intensely studied. Coming from the issue of electrochemical sensors on non-polar liquids the analysis of lubrication oils in the engine of a motor vehicle was taken as an example. The investigation of electrode materials in …

Entwicklung eines kontinuierlichen Extraktionsverfahrens zur Reinigung von Kunststoffschmelzen mittels überkritischem Kohlendioxid
… solubility in scCO2 even for higher molecular substances. Furthermore CO2 is non flammable, ecologically safe, inexpensive and non toxic. One disadvantage of CO2 is its low polarity and thus its low solubility for polar substances. The polarity of the extracting agent can be influenced …

Ultrastructure and functional morphology of adhesive organs and anti-adhesive plant surfaces
… acids, hexadecanoic acid and water. The non-polar substances seemed to form micelles within the water which generally appear as small droplets in light microscopy. The ratio of polar and non-polar components within this emulsion could affect the physical properties of the liquid and therefore …

Rates of evaporation of small drops at low pressures
… developed hold strictly only for the case of non-polar substances. In the case of polar liquids, where a deep transition zone due to long range forces may exist, the model proposed may break down quite seriously. This may account for such effects as very low condensation coefficient and large …
