Ducted fuel injection promises cleaner combustion

By Michael Langley Click the image to watch a video with additional information about ducted fuel injection. An engine innovation first conceived and tested by Sandia scientists has attracted the attention of big business because it synergizes with renewable fuels and takes almost all the soot out of a diesel engine’s exhaust without [...]

Sandia abuses batteries for better energy storage

by Michael Baker | Photograph by Randy Montoya Sandia National Laboratories engineers June Stanley and Chris Grosso demonstrate how the drop tower they built abuses batteries to understand how the lithium-ion cells respond to different types of stress. (Photograph by Randy Montoya) Batteries never really stand a chance against Sandia National Laboratories researchers [...]

Investigations on Anti-biofouling Zwitterionic Coatings for MHK Is Now in Press

Sandia’s Marine Hydrokinetic (MHK) Advanced Materials program has a new publication on the antifouling efficacy of zwiterionic coatings. These polymeric coatings contain no metal and have both positive and negative chemical charges as part of their molecular structure. The coating was investigated in response to finding environmentally friendly materials for MHK devices by the Sandia-UNM [...]

Sandia Develops Stochastic Production Cost Model Simulator for Electric Power Systems

Sandia has developed a software toolkit that uses stochastic programming to perform power system production cost model simulations. Named PRESCIENT, the software produces probabilistic forecasts automatically from deterministic historical forecasts for load, solar, and/or wind power production and their respective actuals, using a technology known as epi-splines. An example of a probablistic solar forecast [...]

New CREW Database Receives First Set of Data

The CREW public benchmark represents analysis of US wind fleet performance based on aggregated fleet reliability data. Sandia’s Continuous Reliability Enhancement for Wind (CREW) project has received its first large set of data, which reassessed its data-collection efforts to target wind-farm owner/operators that have in-house reliability data collection tools. After a lengthy negotiation [...]

Aerodynamic Wind-Turbine Blade Design for the National Rotor Testbed

The NRT blade shape as viewed from the tip and at an elevation angle of 30° above the suction surface. Sandia has designed a new wind-turbine blade for the National Rotor Testbed (NRT) project and for future experiments at the Scaled Wind Farm Technology (SWiFT) facility with a specific focus on scaled wakes. [...]

Sandia Research to Be Featured on Upcoming Cover of Journal of Physical Chemistry B

Several Sandia Joint BioEnergy Institute (JBEI) researchers, in collaboration with others in Kentucky and India, have published, “Theoretical insights into the role of water in the dissolution of cellulose using IL/water mixed solvent systems,” which the editors selected for Journal of Physical Chemistry B’s Nov. 12th issue cover. The continued reliance of the global transportation energy [...]

JBEI Featured in Chemical & Engineering News Cover Article

Researchers at the Joint BioEnergy Institute (JBEI) are working to transform biomass into energy-rich fuel molecules. Headquartered in Emeryville, California, the Joint BioEnergy Institute (JBEI) is now a member of the elite “100/ 500 Club,” having filed its 100th patent application and published its 500th scientific paper.

CRF Experiment Confirms Accepted Oxidation Scheme of Proposed Diesel Alternative: Dimethyl Ether

Combustion Research Facility (CRF) researchers Kai Moshammer, Ahren Jasper, Arnas Lucassen, Arkke Eskola, Craig Taatjes, and Nils Hansen (all in Sandia’s Combustion Chemistry Dept.) as part of an international collaboration reported, in Journal of Physical Chemistry A, detecting and identifying previously undiscovered partially oxidized intermediates. This work provides experimental confirmation of the generally accepted dimethyl [...]
