    • 2.5 D Cavity Balancing 

      Jin, S.; Lam, Yee Cheong (2002-01)
      Cavity balancing is the process of altering the flow front within a cavity through thickness and design changes such that the desired fill pattern is achieved. The 2 dimensional (2D) cavity-balancing algorithm, developed ...

    • An Analytical Solution on Convective and Diffusive Transport of Analyte in Laminar Flow of Microfluidic Slit 

      Chen, X.; Lam, Yee Cheong (2004-01)
      Microfluidic devices could find applications in many areas, such as BioMEMs, miniature fuel cells and microfluidic cooling of electronic circuitry. One of the important considerations of microfluidic device in analytical ...

    • Femtosecond laser processing of crystalline silicon 

      Tran, D. V.; Lam, Yee Cheong; Zheng, H. Y.; Murukeshan, V. M.; Chai, J.C.; e.a. (2005-01)
      This paper reports the surface morphologies and ablation of crystalline silicon wafers irradiated by infra-red 775 nm Ti:sapphire femtosecond laser. The effects of energy fluences (below and above single-pulse modification) ...

    • Generation of Dielectrophoretic Force under Uniform Electric Field 

      Kua, C.H.; Yang, C.; Goh, S.; Isabel, R.; Youcef-Toumi, Kamal; e.a. (2006-01)
      Effective dipole moment method has been widely accepted as the de facto technique in predicting the dielectrophoretic force due to the non-uniform electric field. In this method, a finite-particle is modeled as an equivalent ...

    • Numerical Simulation of Electroosmotic Flow with Step Change in Zeta Potential 

      Chen, X.; Lam, Yee Cheong; Chen, X. Y.; Chai, J.C.; Yang, C. (2005-01)
      Electroosmotic flow is a convenient mechanism for transporting polar fluid in a microfluidic device. The flow is generated through the application of an external electric field that acts on the free charges that exists in ...

    • Particle Migration of Quasi-Steady Flow in Concentrated Suspension for Powder Injection Molding 

      Chen, X.; Lam, Yee Cheong; Tam, Michael K. C.; Yu, S.C.M. (2002-01)
      A hybrid FEM/FDM algorithm for particle migration of quasi-steady flow in concentrated suspension materials is proposed in this study. This hybrid FEM/FDM algorithm in which the planar variables, such as pressure field, ...

    • Particle Transportation Using Programmable Electrode Arrays 

      Kua, C.H.; Lam, Yee Cheong; Rodriguez, I.; Youcef-Toumi, Kamal; Yang, C. (2007-01)
      This study presents a technique to manipulate particles in microchannels using arrays of individually excitable electrodes. These electrodes were energized sequentially to form a non-uniform electric field that moved along ...

    • Plasma polymerization of C[subscript 4]F[subscript 8] thin film on high aspect ratio silicon molds 

      Yeo, L. P.; Poh, S. L.; Lam, Yee Cheong; Chan-Park, Mary Bee-Eng (2005-01)
      High aspect ratio polymeric micro-patterns are ubiquitous in many fields ranging from sensors, actuators, optics, fluidics and medical. Second generation PDMS molds are replicated against first generation silicon molds ...

    • Review of bio-particle manipulation using dielectrophoresis 

      Kua, C. H.; Lam, Yee Cheong; Yang, C.; Youcef-Toumi, Kamal (2005-01)
      During the last decade, large and costly instruments are being replaced by system based on microfluidic devices. Microfluidic devices hold the promise of combining a small analytical laboratory onto a chip-sized substrate ...

    • The Transverse Particle Migration of Highly Filled Polymer Fluid Flow in a Pipe 

      Chen, X.; Tan, K.W.; Lam, Yee Cheong; Chai, J.C. (2003-01)
      Shear-induced particle migration was investigated by using a continuum diffusive -flux model for the creep flow of nickel powder filled polymers, which are viscous with shear-thinning characteristic. The model, together ...
