Contrast agents are used to increase received signal in imaging systems. In the case of ultrasound, such agents are small micron sized gas bubbles. Ultrasound measures the change in acoustic impedance (product of density and speed of sound), but since…

Blender is a free, open-source software package for modeling 3d objects. While Sketchup is much easier to learn, it has a number of limitations that make it more difficult to do more detailed modeling. Blender has a plethora of features, including…

Hello All, My name is Dan Steiner and I am a rotation student that has been working with Dean on designing a modular benchtop apparatus to study in vivo blood dialysis. The purpose of this project is to create a…

Power and battery life for wearable hemodialysis. The pump(s) will consume the most energy of all the components of the system. Other power consumers could include, control circuits, wireless communication, display and warning lights, depending on design. A continuous display…

The purpose of this post is to start a general discussion around the idea of using ultrathin silicon-based membranes and graphene oxide to improve Extracorporeal Liver Support, also called Artificial Liver Support (ALS) for patients with acute liver failure (ALF).…

I wish I had read Tucker’s lat post before trying this, but since I just got the steam jig from the machine shop I wanted to try it out. My mistake in the two transfers I attempted was that I…

The company Protochips is making interesting microfluidic chips and systems for electron microscopy. See this page and this movie. Note their use of integrated spacers as thin as 150 nm to create a flow channel between back-to-back membrane chips. This…
