Sandia Combustion Research Facility (CRF) scientist Christopher Kliewer (in Sandia’s Combustion Chemistry Dept.) won a DOE Office of Science (SC) Early Career Research Program award to develop new optical diagnostics to study interfacial combustion interactions that are major sources of pollution and vehicle inefficiency. The funding opportunity for researchers in universities and DOE national laboratories, now in its sixth year, supports outstanding scientists early in their careers in developing individual research programs and stimulates research […]
The Departments of Energy and Transportation commissioned a technical team through Sandia to examine the properties of tight crude oils as they relate to potential combustion events in the rail transport environment. Key objectives of this investigation are to characterize and define tight crude oils based on their chemical and physical properties, and identify properties that could contribute to increased potential for accidental combustion. This investigation was commissioned in response to the occurrence of several […]
Using only a 9-volt battery at room temperature, a team led by Sandia researcher Jon Ihlefeld (in Sandia’s Electronic, Optical, & Nano Materials Dept.) has altered the thermal conductivity of the widely used material PZT (lead zirconate titanate) by as much as 11% at subsecond time scales. They did it without resorting to expensive surgeries like changing the material’s composition or forcing phase transitions to other states of matter. “We can alter PZT’s thermal conductivity […]
The Department of Energy Office of Energy Efficiency and Renewable Energy’s (DOE-EERE’s) Geothermal Technologies Office (GTO) defines FORGE’s mission as “enabling cutting-edge research and drilling and technology testing, as well as to allow scientists to identify a replicable, commercial pathway to enhanced geothermal systems (EGSs).” In addition to the site itself, the FORGE effort will include a robust instrumentation, data collection, and data dissemination component to capture and share data and activities occurring at FORGE […]
NASA issued a record of decision (ROD) to use a nuclear battery (a multi-mission radioisotope thermoelectric generator) on the next rover to go to Mars, in 2020. Sandia performed the Nuclear Risk Assessment that was the keystone analysis in the Environmental Impact Statement leading up to this ROD.
The next role that Sandia will play in supporting the Mars 2020 mission is to perform the safety analysis and produce the Safety Analysis Report for the Presidential […]
Thermoelectric devices convert heat to electricity and have no moving parts, making them extremely attractive for cooling and energy harvesting applications. Thermoelectric metal-organic frameworks (MOFs) could take these advantages a step further with improved performance, smaller size and flexible designs. MOFs have a crystalline structure that resembles molecular scaffolding, consisting of rigid organic molecules linked together by metal ions.
Sandia researchers have made the first measurements of thermoelectric behavior of a nanoporous MOF, a development that […]
The Department of Energy Office of Science’s National Science Bowl® (NSB) is a nationwide academic competition that tests middle and high school student teams’ knowledge in all areas of science and mathematics. The DOE created the National Science Bowl® in 1991 to encourage students to excel in mathematics and science and to pursue careers in these fields.
The student teams face-off in a fast-paced question-and-answer format, being tested on a range of science disciplines including biology, […]
In April, Sandia and Purdue University signed an extensive, five-year memorandum of understanding (MOU) to establish a strategic alliance that seeks to solve science and technology problems of national importance. The MOU has three principal goals: solve large national problems, sustain and engage human capital, and accelerate adoption of technology.
MOUs such as this one are expected to bolster connections between national research universities and federally funded research and development centers, such as Sandia. The MOU […]
Sandia researcher Hongyou Fan (at the Advanced Materials Laboratory, operated in cooperation with the University of New Mexico) was selected by the Materials Research Society (MRS) and the Kavli Foundation to deliver the 2015 Fred Kavli Distinguished Lecture in Nanoscience. Fan is the first lecturer affiliated with a national laboratory to be so honored. “I am glad that I have an opportunity to promote and enhance Sandia’s reputation as a leading research institute,” he said. […]
Modeling and experiments show that it is feasible to perform multiple-species detection at sub-ppm levels with a low-resolution broad-band infrared laser. Target measurement species include CO2, CH, N2O, NO2, SO2, HCl, and CH4, among others, simultaneously, and without process treatment or dehumidification of the exhaust sample—potentially reducing current emission-monitoring costs and the need for extensive sample preparation. Both the photoacoustic spectroscopy and cavity ring-down methods show promise in this regard.
The photoacoustic spectroscopy method in particular […]
Sandia National Laboratories’ (SNL’s) Twistact and Lawrence Livermore National Laboratory’s (LLNL’s) Optimization of Building Efficiency projects were selected as the Livermore Valley Site’s participants in the Energy Department’s LabCorps pilot program. The LabCorps goal is to accelerate the transfer of innovative clean-energy technologies from DOE national laboratories into the marketplace. “This program underscores the value of the partnership between Sandia California, Lawrence Livermore, and i-GATE to successfully commercializing laboratory ideas,” said LLNL Director Bill Goldstein. […]
As he spoke to oil and gas executives at the IHS Energy CERAWeek conference, Secretary Moniz’s focus was on the nation’s aging energy infrastructure—and everything that should be done to modernize it amid a domestic energy revolution, climate change, and evolving business models. Moniz spoke to the assembled executives about the just-released QER and the changing face of domestic energy.
“A good example of the way you’d like to see things work is in New Jersey […]
The Department of Energy commissioned a technical team through Sandia National Laboratories to examine the properties of tight crude oils as they relate to potential combustion events in the rail transport environment. Key investigation objectives are to characterize and define tight crude oils based on their chemical and physical properties, and identify properties that could contribute to increased potential for accidental combustion.
This investigation was commissioned in response to the occurrence, in the US and Canada […]
The DOE released a report by an independent technical assessment team (TAT) that evaluated the mechanisms and chemical reactions contributing to the failure of a waste drum at the Waste Isolation Pilot Plant (WIPP) in Carlsbad, NM. The TAT concluded that one drum, Drum 68660, was the source of radioactive contamination released during the February 14, 2014, radiological event at WIPP. The contents of Drum 68660 were chemically incompatible and the drum breached as a […]
Flame stability is an important trait of practical combustors that impacts combustion emissions and the ability of the combustor to operate effectively with changing fuel and oxidizer compositions and flow rates. Fuel and oxidizer in combustion systems are rarely perfectly premixed or perfectly segregated as they enter the flame zone. Combustion models must accurately predict the behavior of such mixed-mode combustors. However, few experiments have been performed on mixed-mode turbulent combustion in burners with well-defined […]
As the US Strategic Petroleum Reserve (SPR) storage caverns age, the integrity of the cavern wells has emerged as a significant issue, which requires mitigation. SPR has been holding nitrogen on several cavern storage wells since November 2012.
These wells exhibited some level of anomalous pressurization behavior in the last year that caused concern for their near-term pressure integrity. Some cavern wells passed routine mechanical integrity tests (MITs), but these wells may exhibit long-term pressurization rate […]
