Evaluation of demineralized lignin and lignin-phenolic resin blends to produce biocoke suitable for blast furnace operation (2019)
Journal Article
Castro-Díaz, M., Vega, M. F., Musa, U., Díaz-Faes, E., Barriocanal, C., & Snape, C. (2019). Evaluation of demineralized lignin and lignin-phenolic resin blends to produce biocoke suitable for blast furnace operation. Fuel, 258, Article 116125. https://doi.org/10.1016/j.fuel.2019.116125

Metallurgical coke makers could reduce carbon emissions and material costs by introducing waste lignin in coke oven charges. Two approaches have been studied here to increase the use of lignin in the preparation of metallurgical coke: lignin deminera...

Exploring drivers of litter decomposition in a greening Arctic: results from a transplant experiment across a tree-line (2018)
Journal Article
Parker, T. C., Sanderman, J., Holden, R. D., Blume-Werry, G., Sjögersten, S., Large, D., …Wookey, P. A. (2018). Exploring drivers of litter decomposition in a greening Arctic: results from a transplant experiment across a tree-line. Ecology, 99(10), 2284-2294. https://doi.org/10.1002/ecy.2442

Decomposition of plant litter is a key control over carbon (C) storage in the soil. The biochemistry of the litter being produced, the environment in which the decomposition is taking place, and the community composition and metabolism of the decompo...
