Green chemistry and nanofabrication in a levitated Leidenfrost drop
Green nanotechnology focuses on the development of new and sustainable methods of creating nanoparticles, their localized assembly and integration into useful systems and devices in a cost-effective, simple and eco-friendly manner. Here we present our experimental findings on the use of the Leidenfrost drop as an overheated and charged green chemical reactor. Employing a droplet of aqueous solu...
متن کاملControlled jamming of particle-laden interfaces using a spinning drop tensiometer.
When particles adsorb at a fluid/fluid interface at a sufficiently high concentration, the interface loses mobility and displays solidlike characteristics, a phenomenon called "interfacial jamming". Jamming can arrest interfacial tension-driven morphological coarsening in liquid/liquid or gas/liquid systems and therefore stabilize two phase morphologies with unusual interfacial shapes, for exam...
متن کاملCorrection to Sample Handling and Chemical Kinetics in an Acoustically Levitated Drop Microreactor
Accurate measurement of enzyme kinetics is an essential part of understanding the mechanisms of biochemical reactions. The typical means of studying such systems use stirred cuvettes, stopped-flow apparatus, microfluidic systems, or other small sample containers. These methods may prove to be problematic if reactants or products adsorb to or react with the container's surface. As an alternative...

متن کاملAn Interfacial Tensiometer for Universal Use
The important and fundamental works of Quincke, Hardy, McC. Lewis, Morgan, and lately Harkins and his collaborators have thrown much light on the behavior of liquids at interfaces, and it may seem hardly necessary to develop a new method in order to study this phenomenon, as those existing have reached a high degree of accuracy. However, if the values of the interfacial tensions of pure liquids...
