Saarnio, Sanna (2015): Impacts of Biochar Amendment on Greenhouse Gas Emissions from Agricultural Soils

Saarnio, Sanna (2015): Impacts of Biochar Amendment on Greenhouse Gas Emissions from Agricultural Soils. In Zhongqi He, Fengchang Wu (Eds.): Agricultural and Environmental Applications of Biochar: Advances and Barriers. Madison, WI: Soil Science Society of America, Inc (SSSA special publication, 63).

„Biochar amendment influences soil greenhouse gas (GHG) emissions by altering the microbial transformation conditions in soils in numerous ways. Increased pH, improved nutrient availability, and additional C may increase microbial activity and the release of GHGs. On the other hand, biochar may disturb microbial processes by increasing the C-to-N ratio in the soil or by adsorbing substrates, processed products and enzymes, or by releasing compounds inhibiting microbial activity.“

Uygun, Murat; et al. (2015): Micromotor-Based Biomimetic Carbon Dioxide Sequestration. Towards Mobile Microscrubbers

Uygun, Murat; Singh, Virendra V.; Kaufmann, Kevin; Uygun, Deniz A.; de Oliveira, Severina D. S.; Wang, Joseph (2015): Micromotor-Based Biomimetic Carbon Dioxide Sequestration. Towards Mobile Microscrubbers. In Angew. Chem., pp.[nbsp]n/a-n/a. DOI: 10.1002/ange.201505155

„We describe a mobile CO2 scrubbing platform that offers a greatly accelerated biomimetic sequestration based on a self-propelled carbonic anhydrase (CA) functionalized micromotor. The CO2 hydration capability of CA is coupled with the rapid movement of catalytic micromotors, and along with the corresponding fluid dynamics, results in a highly efficient mobile CO2 scrubbing microsystem.“

Argonne: Copper clusters capture and convert carbon dioxide to make fuel

Press release to Liu, Cong; et al. (2015). „Capture and convert—this is the motto of carbon dioxide reduction, a process that stops the greenhouse gas before it escapes from chimneys and power plants into the atmosphere and instead turns it into a useful product. One possible end product is methanol, a liquid fuel and the focus of a recent study conducted at the U.S. Department of Energy’s (DOE) Argonne National Laboratory.“

Liu, Cong; et al. (2015): Carbon Dioxide Conversion to Methanol over Size-Selected Cu4 Clusters at Low Pressures

Liu, Cong; Yang, Bing; Tyo, Eric; Seifert, Soenke; DeBartolo, Janae; Issendorff, Bernd von et al. (2015): Carbon Dioxide Conversion to Methanol over Size-Selected Cu4 Clusters at Low Pressures. In Journal of the American Chemical Society 137 (27), pp.[nbsp]8676–8679. DOI: 10.1021/jacs.5b03668[nbsp]

„The activation of CO2 and its hydrogenation to methanol are of much interest as a way to utilize captured CO2. Here, we investigate the use of size-selected Cu4 clusters supported on Al2O3 thin films for CO2 reduction in the presence of hydrogen.“
