A recent study in South Africa has confirmed, for the first time, that a vaginal gel formulation of the antiretroviral drug Tenofovir, when topically applied, significantly inhibits sexual HIV transmission to women [Karim et al., Science 32...
Nanoparticle Brownian motion and hydrodynamic interactions in the presence of flow fields [0.03%]
剪切流场中纳米颗粒的布朗运动及水动力学相互作用

Distinct regimes of droplet charging, determined by the dominant charge transport process, are identified for an ultrasonic droplet ejector using electrohydrodynamic computational simulations, a fundamental scale analysis, and experimental ...
Impact of a compound droplet on a flat surface: A model for single cell epitaxy [0.03%]
复合液滴撞击平板的研究：单细胞外延的模型研究
Savas Tasoglu,Gozde Kaynak,Andrew J Szeri et al.
Savas Tasoglu et al.
The impact and spreading of a compound viscous droplet on a flat surface are studied computationally using a front-tracking method as a model for the single cell epitaxy. This is a technology developed to create two-dimensional and three-di...
A boundary element model of the transport of a semi-infinite bubble through a microvessel bifurcation [0.03%]
