Resilient water treatment technologies and challenges for the removal of emerging contaminants – Perfluorinated compounds

Singh R., Singh T.S., Singh R., Singh T.S., University of Virginia, US

Due to their global presence, persistence, and adverse health effects, perflurinated compounds (perfluoroalkyl and polyfluoroalkyl substances PFASs) have become major chemical of concern for drinking water supplies worldwide. Presence of these PFCs in various geographical [...]

Greenhouse Gas Emissions Reductions Research and Development Leading to Cost-Competitive Coal-to-Liquids (CTL) Based Jet Fuel Production

Archer D., U.S. DOE, US

Significant opportunities to reduce GHG emissions of CTL fuels fall under three categories: increasing efficiencies of conversion technologies; supplementing coal with feedstocks and energy inputs that have lower lifecycle GHG emissions; and carbon capture, utilization, [...]

Steam Explosion and Fermentation of Sugar Beets from Southern Florida and Minnesota

Dorado C., Cameron R.G., Cooper K., United States Department of Agriculture, Agricultural Research Service, US

Sugar beets have been grown primarily in the Midwest for the production of table sugar and have recently gained interest for planting and harvesting in other areas of the U.S. for use as cattle feed, [...]

Investigating the Effects of Media and Light Sources on the Growth of Botryococcus Braunii

Sengul A.B., Rahman M.M., Asmatulu E., Wichita State University, US

The reduction of world’s petroleum reserves and the environmental problems created by emissions have increased the interests in alternative energy. Biodiesel is an environmentally friendly and biodegradable alternative fuel that is obtained from renewable sources. [...]

Improving Hybrid Efficiency and Flexibility by Integrating Thermal Energy Storage into the Fuel Cell System

Tucker D., Harun N.F., Zaccaria V., Shadle L., National Energy Technology Laboratory, US

Power plants must be flexible in operation to meet changing load requirements throughout the day while ensuring economic feasibility. As renewable energy systems penetrate the market producing inconsistent power, the primary concern of power plants [...]
