Innovative 3D Glass Fiber Metal Laminate

Abstract A new assembled glass fiber metal laminate has a 3D E-glass fiber fabric core layer, which contains two bidirectional fabrics knitted together by vertical braided glass fiber pillars. Application of resin to core faces [...]

Three-dimensional cell instructive scaffolds to direct stem cell fate

Viswanathan P., Chirasatitsin S., Reilly G., Engler A., Battaglia G., University of Sheffield, UK

Novel biomaterials design rarely incorporates the range of topographical (10nm – 100um) and chemical cues required to influence cell behaviour. Of particular interest is controlling human mesenchymal and embryonic stem cell fate. Recently it has [...]

A High Throughput Multi-stage, Multi-frequency Filter and Separation Device based on Carbon Dielectrophoresis

Martinez-Duarte R., Andrade-Roman J., Collado-Arredondo E., Martinez S.O., Martinez-Duarte R., Madou M., University of California Irvine, US

We present a multi-stage, multi-frequency carbon dielectrophoresis (CarbonDEP) device for high throughput filtering and separation applications in the health care and biotechnology fields. CarbonDEP refers to the use of carbon electrodes to induce DEP. Up [...]

Fluidic and Electrical Characterization of 3D Carbon Dielectrophoresis with Finite Element Analysis

Martinez-Duarte R., Collado-Arredondo E., Cito S., Martinez S.O., Martinez-Duarte R., Madou M., University of California Irvine, US

The following work presents the fluidic and electrical characterization of a 3D electrodes array to be used in high throughput and high efficiency Carbon Dielectrophoresis (CarbonDEP) applications such as multi-stage filters, continuous particle enrichment and [...]

A 20 µm Movable Micro Mobile

Jeon J., Lee J.B., Kim M-J, The University of Texas at Dallas, US

We present design, fabrication, and characterization of an extremely small (20x14 µm) movable 3D micro vehicle. The micro mobile was fabricated using a combination of focused-ion-beam (FIB) for micro/nano parts production, atomic layer deposition (ALD) [...]

New Characterisation Techniques for the Study of Nanoscale Polymeric Systems in Two- & Three-Dimensions

Stokes D.J., Reyntjens S., Jiao C., Hayles M.F., Hubert D.H.W., FEI Company, NL

Activity in the development of polymer-based materials, composites and devices is more intense than ever. At the same time, techniques and methods for their characterisation have become more powerful, giving new insights into the spatial [...]

Single Walled Carbon Nanotubes based Three Dimensional Flexible Electronics

Makaram P., Selvarasah S., Chen C., Busnaina A., Dokmeci M.R., Northeastern University, US

Single Walled Carbon Nanotubes (SWNTs) with their superior electrical and mechanical properties are very strong candidates for future electronic applications. CMOS electronics are constantly being scaled down to accommodate more devices. Alternative device geometries are [...]

Influence of Element Size on the Precision and Required Computational Effort for 3D FEM Interconnect Capacitance Simulations of ULSI DRAM Cells

Hieke A., Infineon Technologies Corporation, US

A fundamental proble of all FEM capacitance computations in MEMS and ULSI is to determine proper mesh size for the elements representing the considered model. In particular, opticaml mesh size selection is crucial for large [...]
