The priming potential of environmentally weathered pyrogenic carbon during land-use transition to biomass crop production (2015)
Journal Article

Since land-use change (LUC) to lignocellulosic biomass crops often causes a loss of soil organic carbon (SOC), at least in the short term, this study investigated the potential for pyrogenic carbon (PyC) to ameliorate this effect. Although negative p... Read More about The priming potential of environmentally weathered pyrogenic carbon during land-use transition to biomass crop production.

Long-term reindeer grazing limits warming-induced increases in CO2 released by tundra heath soil: potential role of soil C quality (2015)
Journal Article

© 2015 IOP Publishing Ltd. The current climate warming in the Arctic may increase the microbial degradation of vast pools of soil carbon (C); however, the temperature sensitivity of decomposition is often highly dependent on the quality of accumulate...

Kinetic and economic analysis of reactive capture of dilute carbon dioxide with Grignard reagents (2015)
Journal Article

Carbon Dioxide Utilisation (CDU) processes face significant challenges, especially in the energetic cost of carbon capture from flue gas and the uphill energy gradient for CO2 reduction. Both of these stumbling blocks can be addressed by using alkali... Read More about Kinetic and economic analysis of reactive capture of dilute carbon dioxide with Grignard reagents.

Correlation of energy storage performance of supercapacitor with iso-propanol improved wettability of aqueous electrolyte on activated carbon electrodes of various apparent densities (2015)
Journal Article

© 2015 Elsevier Ltd. Addition of iso-propanol in the aqueous electrolyte of 1.0mol/L Na2SO4 was found to be most effective at about 8vol.% to minimise electrolyte surface tension, and hence maximise electrolyte wetting on a commercial supercapacitor...
