Project Description The goal of this project is to design an experimental setup to support X-ray characterization experiments for metal halide perovskite (MHP) precursor solutions. (e.g., small angle X-ray scattering (SAXS), X-ray absorption spectroscopy (XAS)). Fabrication of solution-processed perovskite solar cells (PSCs) involves the rapid nucleation and crystallization of MHP...

Project Description This project aims to study the gaps that arise in understanding and supporting self-regulated learning in the newly emerging online learning space, as demonstrated by the varied behaviors of different populations of students. In particular, we will address questions of how learning management system traces indicate successful self-regulated...

Project Description The growth plate, a region of cartilage found in the long bones of growing children, is responsible for healthy bone development and elongation. The growth plate’s function and structure relies on a complex system of both biochemical and biophysical cues. However, in the case of limb paralysis or...

Project Description When non-biological materials are implanted in the body the innate immune system responds by surrounding the material with dense fibrous collagen and persistent inflammation at the surface of the material. This response, deemed the foreign body response (FBR), prevents biomaterials from interacting with the body long-term and contributes...

Project Description Over-farming has led to soil degradation in areas that have been pivotal for maintaining the agricultural landscape. One way that we are able to prevent this issue from progressing is by monitoring the health of soil during growing seasons and using this information to inform farming practices. Our...

Project Description Transmitters used for radio frequency (RF) communications systems (cell phones, wifi, etc) need to be made linear so they don't introduce distortion into the data signal. Normally, this is done with digital signal processing techniques to "pre-distort" a signal as a way to correct for the nonlinearity of...

Project Description Ultrasound imaging is an important tool for medical diagnostics, but we must work to develop imaging sequences that can image faster and with greater clarity to address a wider range of patients and clinical tasks. We have developed a method that involves transmitting from each element on an...

Project Description The Vance Lab at the University of Colorado Boulder specializes in indoor and outdoor air quality investigations, with a special focus on aerosols or particulate matter (PM). PM can range from a few nanometers to micrometers in size and can be generated from a variety of sources, from...

Project Description The conventional technology for recovery of valuable hydrophobic particles from aqueous suspension is froth flotation, where air bubbles rising through the suspension capture the particles and are collected in a froth layer at the top. However, froth flotation is not effective for particles smaller than about 10 microns...

Project Description The carbon cycle controls all life on earth, yet we still lack a complete understanding of the largest reactive organic carbon pool on the planet, dissolved organic matter (DOM). Important ecosystem functions rely and depend on DOM as it controls nutrient availability, light attenuation, microbial respiration, and contaminant...
