Journal Article
Ibrahim, A., Liu, X., Uguna, C. N., & Sun, C. (2022). Hydrodeoxygenation of p-cresol over CuNi@C catalyst derived from metal-organic frameworks precursor. Fuel, 329, Article 125320. https://doi.org/10.1016/j.fuel.2022.125320

Catalytic hydrodeoxygenation is becoming more important industrially due to the urgent need for the conversion of oxygen-rich biomass into a renewable hydrocarbon energy source as means to tackle the climate change crisis. This research examined the... Read More about Hydrodeoxygenation of p-cresol over CuNi@C catalyst derived from metal-organic frameworks precursor.

Should IQOS Emissions Be Considered as Smoke and Harmful to Health? A Review of the Chemical Evidence (2022)
Journal Article
Uguna, C. N., & Snape, C. E. (2022). Should IQOS Emissions Be Considered as Smoke and Harmful to Health? A Review of the Chemical Evidence. ACS Omega, 7(26), 22111–22124. https://doi.org/10.1021/acsomega.2c01527

The chemical evidence that IQOS emissions fit the definition of both an aerosol and smoke, and that IQOS and potentially other heated tobacco products (HTPs) pose some harmful health threats from the range of compounds released even at somewhat lower...

Effect of process variables on producing biocoals by hydrothermal carbonisation of pine Kraft lignin at low temperatures (2022)
Journal Article
Musa, U., Castro-Díaz, M., Uguna, C. N., & Snape, C. E. (2022). Effect of process variables on producing biocoals by hydrothermal carbonisation of pine Kraft lignin at low temperatures. Fuel, 325, Article 124784. https://doi.org/10.1016/j.fuel.2022.124784

Lignin from pulping is recovered in a wet form, making it ideal for hydrothermal carbonisation (HTC). This study investigates the effects of temperature (200–280 °C), residence time (1–6 h), and water to biomass mass ratio (2:1–6:1) on the compositio...

Renewable binders from waste biomass for road construction: A review on thermochemical conversion technologies and current developments (2022)
Journal Article
Weir, A., Jiménez del Barco Carrión, A., Queffélec, C., Bujoli, B., Chailleux, E., Uguna, C., Snape, C., & Airey, G. (2022). Renewable binders from waste biomass for road construction: A review on thermochemical conversion technologies and current developments. Construction and Building Materials, 330, Article 127076. https://doi.org/10.1016/j.conbuildmat.2022.127076

Biobinders (binders manufactured from biomass) are becoming popular in asphalt engineering due to growing environmental concerns of greenhouse gas emissions from the use of fossil fuels and depleting petroleum bitumen reserves. Waste biomass products... Read More about Renewable binders from waste biomass for road construction: A review on thermochemical conversion technologies and current developments.

The effect of oil extraction on porosity and methane adsorption for dry and moisture-equilibrated shales (2022)
Journal Article
Li, W., Stevens, L. A., Meredith, W., Uguna, C. N., Vane, C. H., Zhang, B., Carr, A. D., Zheng, D., & Snape, C. E. (2022). The effect of oil extraction on porosity and methane adsorption for dry and moisture-equilibrated shales. Fuel, 316, Article 123304. https://doi.org/10.1016/j.fuel.2022.123304

The porosity and methane adsorption capacity of shale used to estimate gas in place (GIP) are affected both by moisture and oil residing in the pore structure, as well as oil naturally present from maturation, which can include contaminant drilling m...
