Journal Article
Wiedmann, F., Salama, A. M., & Mirincheva, V. (2014). Sustainable urban qualities in the emerging city of Doha. Journal of Urbanism, 7(1), 62-84. https://doi.org/10.1080/17549175.2013.870088

Various urban qualities are required for sustainable urban development, which is a particular challenge in the case of emerging cities such as Qatar's capital, Doha. Therefore, this paper seeks to introduce a framework concerning how to investigate u... Read More about Sustainable urban qualities in the emerging city of Doha.

Three unobtrusive domestic occupancy measurement technologies under qualitative review (2013)
Journal Article
Naghiyev, E., Gillott, M., & WILSON, R. (2014). Three unobtrusive domestic occupancy measurement technologies under qualitative review. Energy and Buildings, 69, 507-514. https://doi.org/10.1016/j.enbuild.2013.11.033

Almost one third of the UK's total energy is consumed by the domestic sector. Occupancy measurement could have the potential to save significant amounts of that energy, either instantly via a home automation system or retrospectively via post-occupan...

The physical meaning of charge extraction by linearly increasing voltage transients from organic solar cells (2013)
Journal Article
Hanfland, R., Fischer, M. A., Brütting, W., Würfel, U., & MacKenzie, R. C. I. (2013). The physical meaning of charge extraction by linearly increasing voltage transients from organic solar cells. Applied Physics Letters, 103(6), 063904. https://doi.org/10.1063/1.4818267

Carrier mobility in organic solar cells is almost exclusively determined with the Charge Extraction by Linearly Increasing Voltage (CELIV) technique; indeed much of our understanding of the recombination and charge transport mechanisms in organic sol...

Interpreting the density of states extracted from organic solar cells using transient photocurrent measurements (2013)
Journal Article
MacKenzie, R. C. I., Shuttle, C. G., Dibb, G. F., Treat, N., von Hauff, E., Robb, M. J., Hawker, C. J., Chabinyc, M. L., & Nelson, J. (2013). Interpreting the density of states extracted from organic solar cells using transient photocurrent measurements. Journal of Physical Chemistry C, 117(24), 12407-12414. https://doi.org/10.1021/jp4010828

The energetic distribution of trapped carrier states (DoS) in organic photovoltaic (OPV) devices is a key device parameter which controls carrier mobility and the recombination rate; as such, it can ultimately limit device efficiency. Recent studies... Read More about Interpreting the density of states extracted from organic solar cells using transient photocurrent measurements.

Identifying road defect information from smartphones (2013)
Journal Article
Byrne, M., Parry, T., Isola, R., & Dawson, A. (2013). Identifying road defect information from smartphones. Road and Transport Research Journal, 22(1), 39-50

Defect repair, for example potholes, is one of the most common and expensive tasks of road maintenance. One of the difficulties of this form of asset management is in identifying these defects early. Although a defect may take many years to initiate,... Read More about Identifying road defect information from smartphones.

Examining effects of climatic factors on flexible pavement performance and service life (2013)
Journal Article
Qiao, Y., Flintsch, G., Dawson, A., & Parry, T. (2013). Examining effects of climatic factors on flexible pavement performance and service life. Transportation Research Record, 2349(1), 100-107. https://doi.org/10.3141/2349-12

The potential risk of climate change raises interest in how it may affect the deterioration rates of flexible pavements and how pavement service lives would be altered as a consequence. Previous studies demonstrated that temperature is the most influ... Read More about Examining effects of climatic factors on flexible pavement performance and service life.

A framework for investigating urban qualities in emerging knowledge economies: The case of doha (2012)
Journal Article
Wiedmann, F., Salama, A. M., & Thierstein, A. (2012). A framework for investigating urban qualities in emerging knowledge economies: The case of doha. Archnet-IJAR, 6(1), 42-56

Over the last decade Qatar's capital city Doha has been undergoing a new period of urbanisation that has created a new perception of the city as an emerging urban centre in the Gulf region. It has witnessed rapid urban growth driven by economic diver... Read More about A framework for investigating urban qualities in emerging knowledge economies: The case of doha.

Electro-deoxidation of solid chromium oxide in molten chloride salts (2005)
Presentation / Conference Contribution
Gordo, E., Chen, G. Z., & Fray, D. J. (2005, February). Electro-deoxidation of solid chromium oxide in molten chloride salts. Paper presented at TMS Annual Meeting 2005, San Francisco, California, U.S.A

Chromium is industrially produced by aluminothermic reduction of Cr 2O3 or electrodeposition from the aqueous NH 4Cr(SO4)2 solution. The former makes more a expensive product than an electrolytic method because the reductant, aluminium, is produced b...

The use of electro-deoxidation to reduce titanium dioxide and other metal oxides (2001)
Presentation / Conference Contribution
Fray, D. J., & Chen, G. Z. (2001, October). The use of electro-deoxidation to reduce titanium dioxide and other metal oxides. Paper presented at Proceedings of the Fourth International Conference on Materials Engineering for Resources

Titanium is usually extracted by the Kroll process in which titanium tetrachloride is reduced by magnesium to form titanium sponge and magnesium chloride. This is an expensive and time consuming process which makes titanium a very expensive metal. Al... Read More about The use of electro-deoxidation to reduce titanium dioxide and other metal oxides.
