Word Document: Blog Write Up 4.8.19 Over the past two weeks I have been working on creating a protocol to eliminate the organic debris from environmental water samples, leaving only microplastics behind on the silicon filters. The goal for this…

One advantage of our slot nanomembranes is that we can readily image microparticulate debris with simple light microscopy. With that in mind, it should be straightforward to have some image processing along with our microspectroscopy to separate out different particles…

We have long maintained that we can capture more analyte from a sample using a flow-through configuration compared to a tangential configuration. We can confirm this view quantitatively by measuring the amount of material captured on the membrane with equal source…

A collaborator of mine is interested in arranging quantum dots on a surface to demonstrate something called super irradiance. All of the sub-resolution particles could emit as one object (think laser) if the conditions are just so. Ideally, a bunch…

MATLAB updated the way that it creates GUI applications back in 2015, and it is increasingly becoming more functional. Over the years I have been here, we have had more than a few requests to use our pore processing software.…

Summary I need to replace the function of my breath to get water into the femtoliter sized cavity of the monolithic device. I achieve this using a small stream of ethanol vapor as a precursor, and then replace the ethanol…

Alec and Elysia’s study on the migration of infectious bugs through microporous silicon nitride has been useful, however, the size range of the pores is not sufficient to halt the migration. To create smaller pore sizes, I infilled the chips…

We want to create a structure that can more easily control the electric field inside of the Monolith cavities, by adding an electrode specific to each well. My solution is to create a hybrid film stack, replacing some of the…

Kyle has made some progress using the monolith chips, however, the wetting of these chips is difficult and makes the monoliths unattractive to use. I have attempted to create a more replicable wetting protocol. We’ve heard over the summer that…

Background: At the end of August, Greg Schmidt and I were investigating the feasibility of a project that builds off of my PhD research: templating and patterning new materials on top of NPN/microporous nitride. We hope to make composite nanomembranes…
