Energy Harvesting

As part of my thesis, I am trying to get a non-fouling pattern on a substrate which resembles our porous membranes to investigate cell behavior including cell adhesion and migration and to compare with our previous results which was obtained on porous membranes. This study can separate the role of pore edges and disrupted surface…

Although most previous studies suggest a weakened cell-substrate interaction over porous membranes, there are variations in the observed cell responses, likely due to the use of different cell types, substrate materials, and experimental methods. We are seeking to develop a computational model using the Active Brownian Particle (ABP) approach to study the role of pore…

I’ve been thinking a lot about energy storage lately, and I think I’ve found a potential use for pnc-Si in Supercapacitors. What is a supercapacitor? As the name suggests, it’s a double-layer capacitor (EDLC) with very high capacitance values (1-500+ Farads) or a million times more than that of a typical dielectic capacitor. An electrolyte…

SepCon Experiment (Carrie): Does it work in a SepCon format? Use “Protein A Beads and IgG Binding and Filtering (with SepCon Format)” 9/29/09 Make Buffer B at pH 3 9/30/09 1) Rinse off ethanol 2) Add IgG Take absorbance reading of 1 aliquot of IgG (2×10μl samples) [D7= 0.565abs, D8=0.63abs] Transfer beads to 2ml centrifuge…

This is part three of a series of posts on constructing a mathematical model of the movement of gold through a porous membrane. In part one, I implemented William Deen’s mathematical model of the electrostatic and steric effects that contribute to whether a gold nanoparticle will translocate through a pore. The mathematica and matlab code…
