Evaluation of a digitally controlled power electronic emulator for supercapattery (2012)
Conference Proceeding
Kulsangcharoen, P., Rashed, M., Klumpner, C., De, D., Patel, C., Asher, G., & Chen, G. Z. (2012). Evaluation of a digitally controlled power electronic emulator for supercapattery. In 6th IET International Conference on Power Electronics, Machines and Drives (PEMD 2012). https://doi.org/10.1049/cp.2012.0341

Newly developed electrochemical energy storage devices are typically produced as single/small quantity and small size devices. This makes their evaluation very difficult in high power applications that would require production of much larger size dev...

Produced water treatment technologies (2012)
Journal Article
Igunnu, E. T., & Chen, G. Z. (2014). Produced water treatment technologies. International Journal of Low-Carbon Technologies, 9(3), 157-177. https://doi.org/10.1093/ijlct/cts049

Produced water is a complex mixture of organic and inorganic compounds and the largest volume of by-product generated during oil and gas recovery operations. The potential of oilfield produced water to be a source of fresh water for water-stressed oi... Read More about Produced water treatment technologies.

Carbon nanotube/titanium dioxide (CNT/TiO2) core-shell nanocomposites with tailored shell thickness, CNT content and photocatalytic/photoelectrocatalytic properties (2011)
Journal Article
Li, Z., Gao, B., Chen, G. Z., Mokaya, R., Sotiropoulos, S., & Li Puma, G. (2011). Carbon nanotube/titanium dioxide (CNT/TiO2) core-shell nanocomposites with tailored shell thickness, CNT content and photocatalytic/photoelectrocatalytic properties. Applied Catalysis B: Environmental, 110, 50-57. https://doi.org/10.1016/j.apcatb.2011.08.023

Combining carbon nanotubes (CNTs) with TiO2 at the nano-scale level can promote the separation of the electron-hole charges generated upon irradiation. However, charge separation capability depends on the quality of the interfacial contact between CN...

Electro-deoxidation of solid chromium oxide in molten chloride salts (2005)
Presentation / Conference
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...

Extraction of titanium from solid titanium dioxide in molten salts (2004)
Conference Proceeding
Fray, D. J., & Chen, G. Z. (2004). Extraction of titanium from solid titanium dioxide in molten salts. In Cost-Affordable Titanium (9-17)

The search for a cheaper replacement for the Hunter and Kroll Processes has continued ever since titanium was first produced commercially. In 2000, the authors reported that it was possible to reduce titanium and other metal oxides directly to metals... Read More about Extraction of titanium from solid titanium dioxide in molten salts.

The use of electro-deoxidation to reduce titanium dioxide and other metal oxides (2001)
Presentation / Conference
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.

Selecting the power electronic interface for a supercapattery based energy storage system
Conference Proceeding
Klumpner, C., Asher, G., & Chen, G. Z. (in press). Selecting the power electronic interface for a supercapattery based energy storage system. In 2009 IEEE Bucharest PowerTech. https://doi.org/10.1109/PTC.2009.5281965

This paper presents the initial investigations in selecting the topology of the power electronic interface for an energy storage system for power levelling applications based on a novel storage device, the supercapattery. The particularities of the s... Read More about Selecting the power electronic interface for a supercapattery based energy storage system.

Efficiency evaluation of a novel supercapattery stack with a power electronic interface for energy storage systems
Conference Proceeding
Kulsangcharoen, P., Klumpner, C., Zhou, X., Peng, C., Chen, G. Z., Rashed, M., & Asher, G. (in press). Efficiency evaluation of a novel supercapattery stack with a power electronic interface for energy storage systems.

The increase of renewable energy generation seen as the only way to ensure clean and sustainable development, is under scrutiny due to its intermittent nature and an insufficient development of com-plementary technologies such as electrical energy st...
