Effective conductivity of composites of graded spherical particles
K. W. Yu, G. Q. Gu
We have employed the first-principles approach to compute the effective response of composites of graded spherical particles of arbitrary conductivity profiles. We solve the bounda…
Electrokinetic behavior of two touching inhomogeneous biological cells and colloidal particles: Effects of multipolar interactions
J. P. Huang, Mikko Karttunen, K. W. Yu +2
We present a theory to investigate electro-kinetic behavior, namely, electrorotation and dielectrophoresis under alternating current (AC) applied fields for a pair of touching inho…
Electrorotation in graded colloidal suspensions
J. P. Huang, K. W. Yu, G. Q. Gu +1
Biological cells can be treated as composites of graded material inclusions. In addition to biomaterials, graded composites are important in more traditional materials science. In…
Dielectric response of spherical particles of graded materials
K. W. Yu, G. Q. Gu, J. P. Huang
We have studied the effective response of composites of spherical particles with a dielectric profile which varies along the radius of the particles. We developed a differential ef…
Electrorotation of colloidal suspensions
J. P. Huang, K. W. Yu, G. Q. Gu
When a strong electric field is applied to a colloidal suspension, it may cause an aggregation of the suspended particles in response to the field. In the case of a rotating field,…
Relaxation of surface charge on rotating dielectric spheres: Implications on dynamic electrorheological effects
Jones T. K. Wan, K. W. Yu, G. Q. Gu
We have examined the effect of an oscillatory rotation of a polarized dielectric particle. The rotational motion leads to a re-distribution of the polarization charge on the surfac…
