IRGs

In collaboration with Marks and Prof. Alex K. -Y. Jen group (U. Washington), the Ho group has, for the first time, successfully demonstrated a novel organic EO modulator using ZnO and In2O3 as TCO electrodes and device geometry designs. This helped achieve 2.8V switching voltage for a 8mm-long device at wavelength of 1.31μm, which corresponding […]

The primary goal of IRG #2 is to develop and produce materials with superior mechanical properties using polymer-based processing strategies that include polymers, ceramics, metals, and structured composite materials.
Polymers and gels are versatile materials with useful mechanical, electrical and biological functions. Center scientists are developing methods for controlling the properties of these materials by tuning […]

The goal of IRG #3 is to advance the understanding of molecular plasmonics at the single nanoparticle and single molecule levels and to develop the new research tools necessary to accomplish this. The group is working to control and manipulate light on the nanometer-length scale as mediated by localized and propagating surface plasmons. The major […]

IRG-4 research enables novel technological advances in the area of hybrid organic/inorganic nanoelectronic materials by improving fundamental understanding and optimizing processing efficiency across multiple length-scales. The IRG’s collaborative efforts take advantage of several unique and complementary strengths:

Synthesis: organic high-k dielectrics and inorganic semiconductor nanowires.
Processing: single-walled carbon nanotube sorting and printable electronics.
Characterization: scanning probe microscopy and synchrotron […]

This interdisciplinary research aims to develop a new class of “patchy” nanoparticle coatings for uses in biocompatible surfaces and in flexible electronics. The work builds on this research group’s recent progress in using electrostatic interactions to drive self-assembly of charged nanoscopic components into various types of supra-structures.1-3
In this work, the group is using nanoscale electrostatics […]

Coronary artery and peripheral vascular disease are the largest causes of mortality in the United States [1]. To treat the consequences of this disease, clinicians rely on donor veins, arteries, or synthetic vascular grafts. Unfortunately, synthetic vascular grafts have had limited success as they occlude and fail within 5 years when used to replace small-diameter […]

Molecular biology permits custom programming of cells to carry out specific tasks, such as synthesis of specific biomolecules or modification of molecules in the extracellular environment. Further examples include formation of multicellular structures or sending chemical or optical signals in response to detection of specific molecules.
The bacterium Escherichia coli, for which there exists a staggering […]

This seed project synthesizes and evaluates materials for potential use in molecular electronics. This work also uses synthesis to address how molecular structure can control electron transport and function. Focus is directed towards compounds that contain conjugated electron donating and electron withdrawing substituents in their molecular architecture. Appropriate installation of thiol or olefin linkers on […]
