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). Available online at http://dx.doi.org/10.2136/sssaspecpub63.2014.0045  

"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."

FCEA Phonecall: Dan Sarewitz & Jane Flegal phone call

With a few comments on CE. "They discuss the justification for public engagement on emerging technologies, the differences between public/science education as opposed to public deliberation, international accountability when it comes to climate engineering research, and legitimizing science through public engagement."

CoExist: A Crazy Plan To Literally Move The World's Continents To Create Climate Consensus

Not climate engineering but terraforming. "Think about geoengineering for climate change, and you might think of sucking carbon from the air, dumping iron in the ocean, or blocking sunlight with mirrors. Artist and "experimental philosopher" Jonathon Keats has an even crazier suggestion: What if we literally reshaped the Earth?"

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. 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. 8676–8679. DOI: 10.1021/jacs.5b03668 

"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."

Renewables International: 6% of global grain for biofuels
