|Ames Lab employees opened their hearts, wallets and checkbooks to raise $4,498 at this year's Holiday Auction. This was the 12th year for the auction and proceeds went to benefit Youth and Shelter Services ($2,322), the Bethesda Community Food Pantry ($2,036) and United Way ($140).|
The U.S. Department of Energy's Ames Laboratory continues to score high in scientific performance according to the just-released 2013 DOE Laboratory Performance Report Card. Ames Lab received an A- for Mission Accomplishment (Quality and Productivity of R&D).
APPROVED FY14 LDRD Projects:
Cutting-edge scientific analysis at the U. S. Department of Energy is not only speeding technological innovation, itâ€™s helping keep the nation safe. Here at the Ames Laboratory, it means bringing our international reputation for advanced tools and techniques in materials characterization to the forensic field of questioned documents investigation.
Our research group has recently discovered how to polymerize triglycerides such as soybean oil along with common monomeric feedstocks such as styrene to form what is known as a â€œthermoplastic elastomerâ€ (TPE). A TPE is a general category of plastics that range from soft and sticky (one use is in PostIt Notes) to soft elastic materials (used in the soles of shoes) to hard pliable rubbers (used in tires and roads). The vast majority of TPEs are derived from combinations of styrene and butadiene; butadiene is a energy intensive byproduct of ethylene cracking from crude oil.
Bioelectrochemical systems (BES) have recently emerged as a central technology in an attempt to produce electricity. In a BES, bacteria interact with electrodes using electrons, which are either removed or supplied through an electrical circuit. The most recognized type of BES is microbial fuel cells (MFCs), in which useful power is generated from electron donors as, for example, present in wastewater.
Two projects are being offered:
Permanent magnetic materials find wide applications in energy generation. The materials providing best performances (e.g., high energy product), such as NdFeB, contains a large weight percentage of rare earth metals. As rare earth materials are critical materials and is projected to face a shortage in supply, DOE has invested considerable resources to find substitute materials for the rare earth based permanent magnetic materials in a recent APRPA-E REACT call.
Capturing 3D Footwear and Impression Marks near scene of a crime could play an essential role for biometrics survey or crime investigation. Existing laser scanning methods are good at capturing long-range and large areas (e.g. full room, or whole crime scene); and microscopy technology may serve the purpose of capturing micro-scale structures with a few millimeters range. However, there is a lack of affordable technologies that can capture crime scenes in the middle-range (few millimeters to a meter) that could achieve at least 300 dpi (dots per inch) in 3D.
