| 1 | Spreading and Wetting Behaviour of Trisiloxanes显示文摘Wetting and spreading processes which involve surfactant solutions are widely used in numerous industrial and practicalapplications nowadays.The performance of different non-ionic surfactants may vary significantly and so far superspreadersolutions show the most promising spreading ability.The addition of trisiloxane surfactants to water was proven to enhancewetting,even on hydrophobic surfaces,on which conventional surfactants seem to have little or no effect.Although theseextraordinary surfactants have been extensively studied over recent years,complete understanding of their underlying mechanismsand a suitable mathematical model are still lacking.Here we present a possible explanation for the impressive performanceof trisiloxane,which is compared to wetting enhancement of a conventional surfactant.Additionally,we will explain whythe hydrophobicity of the surface is a crucial factor for the spreading phenomenon.Light will be also shed on the effect of the pHof the solution to which surfactants are added.Finally,we will investigate long-term effects of the water environment on trisiloxanewetting ability and discuss if ageing may significantly affect their performance. | Jovana Radulovic Khellil Sefiane Martin E.R.Shanahan | 2009 | Journal of Bionic Engineering2009，6，4： | 14 |
| 2 | A Study of the Velocity Field during Evaporation of Sessile Water and Water/Ethanol Drops显示文摘Many studies have investigated evaporation of sessile drops in an attempt to understand the effect of wetting on theevaporation process.Recently interest has also increased in the deposition of particles from such drops,with evaporative massflux being deemed to be responsible for ring-like deposits,and counteraction of the mass flux by Marangoni convection explainingmore uniform deposition patterns.Understanding of such deposition processes is important in biological applications,such as the Litos test-system endorsed by the Russian Ministry of Health for diagnosis of urolithiasis and the evaporation ofcolloidal drops for depositing and organizing proteins and DNA.In most cases where deposition from evaporating drops hasbeen studied,velocity information is inferred from the final deposition pattern or from mathematical modeling based on simplifiedmodels of the physics of the evaporation process.In this study we have directly measured the flow velocities in the baseof sessile drops,using micro particle image velocimetry,viewing the drop from below,through the cover slide.For water drops,a radial pattern of flow was observed with a maximum velocity close to but not at the pinned outer edge.For ‘azeotropic’ethanol/water mixtures,the velocity field is more chaotic to begin with,passing through a phase involving three or four recirculationcells and finally having the same radial pattern as for water drops. | John R.E.Christy Khellil Sefiane Euan Munro | 2010 | Journal of Bionic Engineering2010，7，4： | 2 |
