Towards a Mechanistic Understanding of Carbon Stabilization in Manganese Oxides (2015)
Journal Article
Johnson, K., Purvis, G., Lopez-Capel, E., Peacock, C., Gray, N., Wagner, T., …Greenwell, C. (2015). Towards a Mechanistic Understanding of Carbon Stabilization in Manganese Oxides. Nature Communications, 6, Article 7628. https://doi.org/10.1038/ncomms8628

Minerals stabilize organic carbon (OC) in sediments, thereby directly affecting global climate at multiple scales, but how they do it is far from understood. Here we show that manganese oxide (Mn oxide) in a water treatment works filter bed traps dis... Read More about Towards a Mechanistic Understanding of Carbon Stabilization in Manganese Oxides.

Computing with carbon nanotubes: optimization of threshold logic gates using disordered nanotube/polymer composites (2015)

NH 4 Cl Alternative to the CdCl 2 Treatment Step for CdTe Thin-Film Solar Cells (2014)
Journal Article
Major, J. D., Bowen, L., Treharne, R. E., Phillips, L. J., & Durose, K. (2015). NH 4 Cl Alternative to the CdCl 2 Treatment Step for CdTe Thin-Film Solar Cells. IEEE Journal of Photovoltaics, 5(1), 386-389. https://doi.org/10.1109/jphotov.2014.2362296

The CdCl 2 treatment is a key step in CdTe solar cell fabrication. However, despite its near ubiquitous use, the process is nonideal as CdCl 2 is both expensive and potentially hazardous to utilize in processing. In this paper, we report on the devel...

Assessment of photovoltaic junction position using combined focused ion beam and electron beam-induced current analysis of close space sublimation deposited CdTe solar cells (2014)
Journal Article
Major, J. D., Bowen, L., Treharne, R., & Durose, K. (2014). Assessment of photovoltaic junction position using combined focused ion beam and electron beam-induced current analysis of close space sublimation deposited CdTe solar cells. Progress in Photovoltaics, 22(10), 1096-1104. https://doi.org/10.1002/pip.2507

A major limitation of the cross‐section electron beam‐induced current method—the use of roughly fractured surfaces to provide the cross‐section—has been overcome with the use of focused ion beam microscope sample preparation. Using this method, it wa...
