Abstract
Self-assembly is the spontaneous and reversible organization of components into ordered structures, representing an alternative to the conventional manufacture of systems made of components from milli to nano scales. First commercial applications of self-assembly have appeared in recent years, for example in the fabrication of radio frequency identification tags. However, the full impact of this new approach towards hetero system integration will only be realized once self-assembly can be programmed on demand. This presentation gives an overview of several projects that aim at programmable self-assembly. A key concept is the “programmable surface” – an interface whose properties can be controlled with high spatial and temporal resolution. Several crucial topics are discussed: real time control of interfacial properties; optimization of binding site designs; and algorithms for the modeling and control of self-assembly. Promising novel manufacturing methods are emerging that combine the precision and reproducibility of semiconductor fabrication with the scalability and parallelism of stochastic self-assembly and with the specificity and programmability of biochemical processes.

IMG Seminar: Surface Micromachined Multilayer Composite right/left Handed Metamaterial for Highly Compact RF Circuits
Event Date:
Wednesday, September 22, 2010 - 16:30 - 17:00
Event Location:
Larsen 234 Please note that this week's seminar is from 4PM (not 3PM) due to speaker's conflict.

Speaker: David Senior
Abstract: Highly compact metamaterial devices are demonstrated by combining the composite right-left handed transmission line approach with a multilayer surface micromachined fabrication processusing SU8 as a dielectric layer. Multiband microwave metamaterial applications for ISM frequencies of 2.4GHz and 5.8GHz are implemented The use of microfabrication techniques eliminates the necessity of using surface mounting device (SMD) based lumped components and makes the CRLH structures compatible and integrable with CMOS/MEMS processes while allowing batch fabrication of multiple devices.
IMG Seminar: A High Gain Circular Polarization Antenna using Metamaterial Slabs

Speaker: Cheolbok Kim
Abstract: Modern satellite communication systems often demand low-profile, wide bandwidth, high gain, and circular polarization antennas. For this applications, a high gain circular polarization antenna with metamaterial slabs has been proposed. Metamaterial slabs having periodic circular lattices have been used to focus beam while fan-shaped patches are added on the slabs to generate circular polarization. The proposed antenna has shown a good axial ratio at the resonant frequency band. It also has shown a simulated gain improvement and transmission gain improvement. In addition, the left/right handed polarization is simply controlled by turning over metamaterial slabs.
IMG Seminar: Spatially Controlled Electrospun Solid Gradient Aligned Nanofiber Tissue Scaffold for Guided Spiral Ganglion Neuron Culture
Event Date:
Wednesday, September 15, 2010 - 15:00 - 15:30
Event Location:
Larsen 234 Speaker: PitFee Jao
The direction of cell growth is associated with chemical, structural and/or mechanical properties of the substrate. Structurally, electrospun nanofibers provide a suitable environment for cell attachment and proliferation due to their similar physical dimension to that of the extracellular matrix. Furthermore, by modulating the topographical features of nanofibers, which include fiber diameter and orientation, cell growth and its related functions can be modified. Here, we demonstrate a solid gradient scaffold for directional growth of spiral ganglion neurons (SGNs).
