Vesiculation mechanisms mediated by anisotropic proteins
Ke Xiao, Chen-Xu Wu, Rui Ma
Endocytosis is an essential biological process for the trafficking of macromolecules (cargo) and membrane proteins in cells. In yeast cells, this involves the invagination of a tub…
Dynamics of droplets driven by electrowetting
Ke Xiao, Chen-Xu Wu
Even though electrowetting-on-dielectric (EWOD) is a useful strategy in a wide array of biological and engineering processes with numerous droplet-manipulation applications, there…
How does an external electric field trigger the Cassie-Baxter-Wenzel wetting transition on a textured surface?
Ke Xiao, Xi Chen, Chen-Xu Wu
Understanding the critical condition and mechanism of the droplet wetting transition between Cassie-Baxter state and Wenzel state triggered by an external electric field is of cons…
Electrostatics in a crooked nanochannel in a newly developed curvilinear coordinate system
Xi Chen, Ke Xiao, Rui Ma +2
Both biological and artificial nanochannels in crooked shape exhibit unusual transportational characteristics, bringing about a challenge to the traditional theoretical analysis of…
Critical condition for electrowetting-induced detachment of a droplet from a curved surface
Ke Xiao, Chen-Xu Wu
Based on energy conservation, we derive a critical condition theoretically for electrowettinginduced droplet detachment from a hydrophobic curved surface. Phase diagrams are constr…
Formation of a fast "lane" for positional transition in a microparticle-suspended nematic liquid crystal cell
Ke Xiao, Xi Chen, Xuezheng Cao +1
In this paper, based on the numerical calculation of total energy utilizing the Green's function method, we found that the external electric field applied to a microparticle-suspen…
Freedericksz-like positional transition of a micro-droplet suspended in a nematic cell
Ke Xiao, Xi Chen, Chen-Xu Wu
In this paper, a Freedericksz-like positional transition is found for a spherical micro-droplet suspended in a nematic liquid crystal cell in the presence of an external electric f…
Synthetic cooling translational mode of an optically trapped nanoparticle through librational mode
Ke-Wen Xiao, Anda Xiong, Nan Zhao +1
We systematically investigate the multi-stability behaviour and cooling of both librational and translational modes of an optically levitated nonspherical nanoparticle. By expandin…
Sensitivity of Displacement Detection for a Particle Levitated in the Doughnut Beam
Lei-Ming Zhou, Ke-Wen Xiao, Zhang-Qi Yin +2
Displacement detection of a sphere particle in focused laser beams with quadrant photodetector (QPD) provides a fast and high precision way to determine the particle location. In c…
Bistability and squeezing of the librational mode of an optically trapped nanoparticle
Ke-Wen Xiao, Nan Zhao, Zhang-qi Yin
We systematically investigate the bistable behavior and squeezing property of the librational mode of a levitated nonspherical nanoparticle trapped by laser beams. By expanding the…
Optical Levitation of Nanodiamonds by Doughnut Beams in Vacuum
Lei-Ming Zhou, Ke-Wen Xiao, Jun Chen +1
Optically levitated nanodiamonds with nitrogen-vacancy centers promise a high-quality hybrid spin-optomechanical system. However, the trapped nanodiamond absorbs energy form laser…
Multidimensional optical fractionation with holographic verification
Ke Xiao, David G. Grier
The trajectories of colloidal particles driven through a periodic potential energy landscape can become kinetically locked in to directions dictated by the landscape's symmetries.…
