Dispersion of Carbon Nanotubes with Organic Dyes

Zhang W., Wu C., Zhang W., Dalian University of Technology, CN

Owing to the presence of van der Waals’ forces, carbon nanotubes (CNTs) have the propensity to aggregate together and form bundles, which considerably hinders their applications. In this paper, organic dyes were used to suspend [...]

The effect of Rheological Property of Ink on the Generation of Inkjet Droplet

Yoo H., Kim C., Korea university, KR

In inkjet printing the ink is usually a suspension of particles in liquid. Suspensions usually have shear-thinning viscosities. Also they have large zero shear viscosities. To understand the jetting and drop generation mechanism we investigated [...]

Simulation of a Polymer Drop in a Shear Field with Dissipative Particle Dynamics Method

Chen S., Phan-Thien N., Fan X.J., Khoo B.C., National University of Singapore, SG

In the present study, the dynamics of polymer drops in micro channel under both steady state and transient shear flow conditions are investigated using Dissipative Particle Dynamics method. The polymer drop is made from finitely [...]

Nonlinear Mechanics of Suspension Beams for a Micromachined Gyroscope

Davis W.O., Pisano A.P., University of California-Berkeley, US

We present a method for the calculation of the coefficients of cubic stiffening for tether-suspended micromachined systems. The analysis is based on a nonlinear rod theory, and enables the prediction of the maximum achievable motion [...]
