Capillary filling in nanochannels : modeling, fabrication and experiments
While capillary filling in channels of micrometers scale is experimentally verified to obey Washburn's law well, the speed of capillary filling in nanochannels is noticeably lower than described by Washburn's formula. This ...
Magnetowetting and sliding motion of a sessile ferrofluid droplet in the presence of a permanent magnet
Motion of a droplet on a planar surface has applications in droplet-based lab on a chip technology. This paper reports the experimental results of the shape, contact angles, and motion of ferrofluid droplets driven by a ...
Mass transport in nanochannels
With the advancement in ultra precision technologies and micromachining processes, the fabrication of well defined nanochannels has become feasible. Nanochannels have applications in various fields such as biomedical ...
Capillary filling in closed end nanochannels
We investigated the interactions between liquid, gas, and solid phases in the capillary filling process of closed-end nanochannels. This paper presents theoretical models without and with absorption and diffusion of gas ...
High-throughput micromixers based on acoustic streaming induced by surface acoustic wave
Flow characteristics in microfluidic devices is naturally laminar due to the small channel dimensions. Mixing based on molecular diffusion is generally poor. In this article, we report the fabrication and characterization ...
