Main Heading

 

Our research spans the fields of solid-state, physical, and materials chemistry. We explore new synthesis routes to structurally and chemically tunable carbon-based materials with a chief interest in their application for energy storage. We have a special fondness for porous materials, especially those that push forward the frontier of how "porosity" is defined at a molecular scale. Contributing fundamental insights into gas and ion physisorption phenomena at the solid interface is also a goal of our work, using classical equilibrium thermodynamics and statistical mechanics.

THE SCOOP

We are now a "three year old" research group, having kicked off in January 2017. Lab rotations in our group are well underway and we are looking for team members with enthusiasm for hands-on projects ranging from gas manifold apparatus design/construction (some have jokingly called this "space plumbing") to classic solid-state chemistry (quartz-blowing and high-temperature synthesis). Gas adsorption measurements are a "bread and butter" activity in this group spanning almost all projects. Our theoretical department is also seeking keen minds with an interest in thermodynamics and statistical mechanics to answer frontier questions in adsorptive energy storage at high pressures. Our work covers a lot of different bases - rotate in and take a look!


Work With Us!

Grad Students:

Our group is seeking PhD students; if your interests are well-aligned with our activites, please contact Nick directly. For more information on pursuing a PhD in our department, check out the [Chemistry Admissions] page. Those interested in an interdisciplinary, materials-focused curriculum should check out the newly developed [Materials Science] program. Both programs are relevant to our group.

Undergrad Students:

We are very excited to host undergraduate projects that fall within the general outline of our work. This includes students from abroad seeking international laboratory experience in the western US (e.g., Master's thesis projects). Please contact Nick directly or stop by the lab.

Postdocs:

We do not currently have an open postdoctoral position, but applications for funding would be enthusiastically supported in relevant cases.

  • May 14th 2020  Physisorption Visualized

    Electron Density Difference Map

    The approach of an adsorbate molecule to a surface is accompanied by a change in the electron density of both the adsorbent and the adsorbate. For nonpolar molecular adsorption on carbon surfaces, this is the physical culmination of the weak but ubiquitous phenomenon known as London dispersion forces. Recent calculations by Rylan Rowsey and our (growing!) computational team have shed unprecedented insight into the role of these weak forces in the storage of small molecular fuels: hydrogen and methane. We look forward to publishing the results soon. In the meantime, we cannot help but share an animation of the electron density difference plot corresponding to methane (the “lander”) adsorption on a molecular maquette of porous carbon known to us as MPh (the “surface”). Red indicates a higher density, and blue indicates a lower density upon adsorption. Enjoy!

       
  • Mar 24th 2020  Atomistic Structures of ZTC: a Review

    Manuscript accepted: we review the ~10 atomistic models reported to date for FAU-ZTC, the archetypical variant of one of our lab's favourite materials (zeolite-templated carbon). Importantly, some recent models have devolved to be less accurately representative of real-world ZTCs, an issue we endeavour to bring directly to light in this work. We hope to emphasize that while schwarzite is a fascinating hypothetical material, ZTCs are still far from exhibiting the fundamental criteria to be considered as such today. For all of the details of Erin's hard work, and the full collection of CIFs for your own personal amusement, see [here].
