Fall 2009
Resonant microcantilevers are promising transducers for bacteria detection because of their high sensitivities. Surface stress and mass from adsorbates affect the resonant frequency. We developed a novel method for decoupling the frequency contributions of a change in mass and surface stress on a...

The sources of inducing field gradients and their implications are investigated inside the microfabricated post arrays. A parametric study is conducted to understand how the posts arrangements, distance, and size change the field and field gradients. The results provide criteria where the...

Theoretical and Experimental Investigation on the Use of Surface Acoustic Wave Sensors for Evaluating the Adhesion of SU-8 Thin Films
DownloadFall 2015
This research investigates the use of a SU-8/AlN/Si SAW sensor for evaluating the adhesion of SU-8 thin films. A theoretical model is developed to plot the wave dispersion profile for the SU-8/AlN/Si configuration. A spring interface model is utilized to represent the SU-8/AlN interface using a...

Nanophotonic detection of nanomechanical structures for use toward mass sensing applications
DownloadSpring 2014
Nanomechanical beam resonators show much promise for use in integrated on-chip mass sensing systems. This follows from their own very small masses and also their ability to store the mechanical energy of their oscillations to produce strong measurable mechanical response signals. To achieve...

Spring 2013
Research was undertaken into the organic semiconductors tris(8- hydroxyquinoline)aluminum (Alq3) as well as bis(8-hydroxyquinoline)zinc (Znq2) to the effect of improving achievable morphological control using an inexpensive evaporation based solution synthesis method. By varying experimental...

Combination of AC electrothermal and Dielectrophoresis realized by 3D Electrodes to Concentrate Particles
Download2022-06-01
Fathy, Jino, Wang, Ziying, Lai, Yongjun
In this paper, a particle microconcentrator is designed and simulated that works by combining the AC electrothermal (ACET) and Dielectrophoresis (DEP) forces. The microconcentrator consists of a PMMA channel with copper electrodes on the walls and bottom of the channel. On each side of the...

A novel mouse model of acute antibody-mediated transplant rejection shows simultaneous complement activating and anti-inflammatory effects of donor specific IgG antibodies
DownloadFall 2013
We developed a small animal model of pure antibody-mediated rejection (ABMR) by utilizing fully major histocompatibility complex (MHC) mismatched kidney allografts in mice. By examining resultant ABMR pathology, we show that terminal complement products C5a and C5b-9 are crucial in establishing...
