Towards nanofabrication with UV femtosecond fiber laser

Huang H., PolarOnyx, Inc., US

In this paper, a UV fs fiber laser was used for direct writing nanofabrication on different materials. The laser used is a commercialized mode-locked fiber laser (PolarOnyx Uranus Series), generating typically Gaussian shape pulses (750 [...]

Milling Process Control with Dimensional Feedback on a Focused Ion Beam – Scanning Electron Microscope System (FIB-SEM)

Sanabia J.E., Raith USA, Inc., US

In nanofabrication and nanoanalysis, focused ion beam – scanning electron microscope (FIB-SEM) systems are increasingly used for demanding patterning tasks which rely on precise pattern placement and/or dimension control. Easily verifying and correcting for patterning [...]

Design and Fabrication of a Large Scale Electric Field Array Device for Directed Self-Assembly of Multilayer BioDerivatized Nanoparticle Materials

Heller M.J., Song Y., University of California San Diego, US

In earlier work, an electronic microarray device was used to carry out a bottom-up approach for the directed self-assembly of higher order 3D structures from biotin/streptavidin, DNA and enzyme derivatized nanoparticles. Structures with up to [...]

Comparison and Critical Analysis of Experimental Results and Correlations for Thermal Conductivity of Nanofluids

Bandarra Filho E.P., Oliveira G.A., Wen D., Federal University of Uberlandia, BR

Suspensions of nanoparticles in liquids, known recently as “nanofluids,” have generated considerable interest for their potential to enhance the heat transfer in thermal systems, and reduce the possibility of erosion, sedimentation and clogging that plagued [...]

Dynamics of Magnetic Nanofluids with Frozen-in Magnetization

Sokolov V.V., Moscow State University of Instrument Engineering and Computer Science, RU

It was shown that in an ideal non-conducting magnetic nanofluid with frozen- in magnetization there are three types of waves: slow and fast magnetosonic waves and Alfvén -type wave. Alfvén -type wave propagating in non-conducting [...]

Micro-particle Electrical Conduction through Human Blood

Abdalla S., Al-Ghamdi A.A., Marzouki F., King Abdulaziz University Jeddah, SA

The electric properties of human blood is vital. This is normal because this viable fluid have huge quantity of unexplored domains about its properties. For example, only few authors have examined the correlation between the [...]

Nanoparticle transport models in confined fluids

Mahadevan T.S., Kojic M., Milosevic M., Isailovic V., Filipovic N., Ferrari M., Ziemys A., The Methodist Hospital Research Institute, US

Mechanisms of nanoparticle (NP) and microparticle (MP) transport in confined spaces and role of material properties are not clearly understood, and transport models may not be complete. Here we present recently developed models of convective [...]

Modeling Particle-Fluid Coupling and its Impact on Magnetic Particle Transport in Microfluidic Systems

Khashan S.A., Furlani E.P., University at Buffalo (SUNY), US

Applications of magnetic particles have grown dramatically in recent years, especially for emerging microfluidic applications in the fields of microbiology, nanomedicine and biotechnology where they are commonly used to sort and separate biomaterials. Magnetic particles [...]

SUEX for High Aspect Ratio Micro-Nanofluidic Applications

Johnson D., Goettert J., Singh V., Yemane D., DJ DevCorp, US

Microfluidics applications can benefit from a dry film approach in multiple ways – particularly in the preparation of multi-layer, multi-level fluidic channels and structures on patternable substrates and covers. In addition, polymer microreactors and other [...]
