This 'coffee ring effect' also occurs in other materials. Researchers from the Departments of Chemical Engineering and Chemistry at KU Leuven have now discovered how to counteract coffee rings with 'surfactants', i.e. soap. The key to the discovery was not a kitchen towel, but a bacterium that counteracts the coffee ring effect at the microscopic level. http://phys.org/news287744927.html Chemistry - Other Tue, 14 May 2013 10:09:01 EST news287744927 Many kinds of cinnamon, cinnamon-flavored foods, beverages and food supplements in the United States use a form of the spice that contains high levels of a natural substance that may cause liver damage in some sensitive people, scientists are reporting.

But plastic food packaging is made of multiple layers designed to act as a barrier for oxygen or bacteria. "Each of these layers is made by a different manufacturer. Still, at the end of the chain, the food manufacturer who sells the packaged product is the sole responsible for food safety," notes Olivier Vitrac, a researcher at the Genial joint research unit of the National Institute of Agricultural Research (INRA-Agroparistech), located in Massy, near Paris. Scientists have been addressing the issue of such potentially harmful molecules diffusing from one layer to the next in food packaging, susceptible to ultimately contaminate the food.
