CatCost is a state-of-the-art cost estimation tool designed to reduce the cost uncertainty associated with pre-commercial catalyst materials. The tool combines industry-standard cost estimation methods and resources into an intuitive suite of tools to bring actionable cost insight to every step of catalyst research and development. CatCost™ allows the rapid development of comprehensive catalyst cost estimates. It incorporates detailed insight into manufacturing methods, especially for precommercial catalysts, without requiring any process design experience.

Surface Phase Explorer
G.A. Ferguson, V. Vorotnikov, N. Wunder, J. Clark, K. Gruchalla, T. Bartholomew, D.J. Robichaud, and G.T. Beckham. 2016.

Understanding the coadsorption of two species on a surface requires the exploration of phase diagrams. To facilitate exploration this web tool creates interactive and downloadable phase diagrams from ab initio data. With SPE it is possible to create surface ab initio phase diagrams for single species adsorbing to a surface as well as coadsorption of two species to a surface, and visualize the Wulff Construction of the surface at any temperature and pressure. Explore the entire temperature and pressure range for all adsorbates using interactive and downloadable charts.


K. Gruchalla. 2020.

Personal collection of sand digital microscopy.

NMT Common Data Set Observable Notebook
K. Gruchalla. 2020.

An Observable notebook examining the NMT Common Data Sets from 2004-2019, focusing on enrollment, persistence, and tuition. The notebook was developed in response to discussion on the NMT Alumni Group.

Walking the Digits of π
K. Gruchalla. 2019.

The visualization shows a deterministic walk generated by the first 100,000 digit expansion of π. The walk takes a step in one of ten 36° increments depending on the digit. The colormap repeats every 10,000 digits.
