Mechanical Compression to Characterize the Robustness of Liquid Marbles.
In this work, we have devised a new approach to measure the critical pressure that a liquid marble can withstand. A liquid marble is gradually squeezed under a mechanical compression applied by two parallel plates. It ruptures at a sufficiently large applied pressure. Combining the force measurement and the high-speed imaging, we can determine the critical pressure that ruptures the liquid marb...
متن کاملRemotely Controllable Liquid Marbles
With the ongoing need for miniaturized systems in many biological and chemical applications, there is an increasing demand for the development of versatile methods for controllable transport and manipulation of small volumes of liquids. [ 1–9 ] Recently, liquid marbles — liquid droplets encapsulated by self-organized hydrophobic particles at the liquid/air interface — have been revealed as a ne...
متن کاملCoalescence of electrically charged liquid marbles.
In this work, we investigated the coalescence of liquid water marbles driven by a DC electric field. We have found that two contacting liquid marbles can be forced to coalesce when they are charged by a sufficiently high voltage. The threshold voltage leading to the electro-coalescence sensitively depends on the stabilizing particles as well as the surface tension of the aqueous phase. By evalu...
متن کاملfrom linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
15 صفحه اولMechanical properties of How to characterize differen
Face deformations during speech in different styles are observed by measuring movements of 65 markers glued on the subject's face including the lips. A factor analysis decomposes lower lip movements generated by jaw gestures and those by intrinsic lip gestures. We then characterize mechanical properties of these movements in terms of global variables calculated over an utterance as the total mo...
