Vitrification and levitation of a liquid droplet on liquid nitrogen.
The vitrification of a liquid occurs when ice crystal formation is prevented in the cryogenic environment through ultrarapid cooling. In general, vitrification entails a large temperature difference between the liquid and its surrounding medium. In our droplet vitrification experiments, we observed that such vitrification events are accompanied by a Leidenfrost phenomenon, which impedes the hea...
متن کاملUltra-violet sterilization of liquid nitrogen prior to vitrification.
Sir, Regarding the biosafety of direct exposure of tissue/cells to liquid nitrogen (LN2) during the vitrification procedure when using ‘open carriers’, debated by Wang (2009) and Isachenko et al. (2009) in the July 2009 issue of this journal, we would like to disagree. We strongly dispute the proposed inefficacy of ultra-violet (UV) treatment of LN2 to guarantee the absence of contamination by ...
متن کاملDynamic and Deformation of a liquid Droplet in a Convective Two-Dimensional Laminar Flow
The objective of this research is to develop an accurate numerical method to be used in showing the deformation of a liquid fuel droplet in a convective field. To simultaneously solve the internal liquid droplet flow field as well as the external gas phase flow field, a nonstaggered rectangular grid system without any coordinate transformation is used. Transition from the gas field to the liqui...
متن کاملVitrification of a monatomic 2D simple liquid
A monatomic simple liquid in two dimensions, where atoms interact isotropically through the Lennard-Jones-Gauss potential [M. Engel and H.-R. Trebin, Phys. Rev. Lett. 98, 225505 (2007)], is vitrified by the use of a rapid cooling technique in a molecular dynamics simulation. Transformation to a crystalline state is investigated at various temperatures and the time-temperature-transformation (TT...
متن کاملEvaporation of a Liquid Droplet
Two idealized models for the preheat s tage of liquid droplets are ana lyzed theoretically . These models conta in the effects of transie nt heat conduction and evaporati on. It is assumed that the droplet surface a rea decreases linearly with time. This assumption necessitates the solution of mov ing boundary problems . These models, however, do not consider gas-phase mass transport . In the f...
