Fluid Dynamics Works on Nanoscale in Real World
Researchers at the In 2000, Georgia Tech researchers showed that fluid dynamics theory could be modified to work on the nanoscale, albeit in a vacuum. Now, seven years later they've shown that it can be modified to work in the real world, too – that is, outside of a vacuum.
Understanding the motion of fluids is the basis for a tremendous amount of engineering and technology in contemporary life. The mathematical principle that describe these rules wave put forth more than 100 years ago and are known as the Navier-Stokes equations. They are well-known and understood by any scientist or student in the field. But now that researchers are delving into the realm of the small, an important question arisen: namely, how do these rules work when fluids and flows are measured on the nanoscale? continue

Theory Aims To Describe Fundamental Properties of Materials
Gold is shiny, diamonds are transparent, and iron is magnetic. Why is that? The answer lies with a material’s electronic structure, which determines its electrical, optical, and magnetic properties. Sandia relies extensively on using and controlling such properties, for everything from assuring weapons reliability to creating devices from nanomaterials.
Predicting a material’s properties by first calculating its electronic structure would cut down experimental time and might lead researchers to uncover new materials with unexpected benefits.continue

NEW! White Paper on Best Practices for Managing Lab Chemical Inventory
ChemSW, Inc.’s latest white paper details best practices in chemical
inventory management, providing insights to ensure system adoption
and successful incorporation into lab processes. Reasons why systems
fail and why they succeed are examined, as well as the true costs
associated with chemical inventory management and cost savings
that result when such a system is optimized for maximum effectiveness.

National Science Foundation and Department of Homeland Security Partner to Address Nuclear Threats
The National Science Foundation (NSF) and the Department of Homeland Security's (DHS) Domestic Nuclear Detection Office (DNDO) have issued a joint solicitation to encourage long-term, transformational advances in nuclear detection technology.
The agencies envision the research leading to next-generation detection systems for identifying nuclear weapons, nuclear material, radiation dispersal devices and related threats.
"Five NSF directorates and two offices will be participating in the initiative," said NSF program director Bruce Hamilton. "Expertise will span multiple academic disciplines, necessary for forming a comprehensive platform to guide fundamental research on domestic nuclear detection." continue

Conference Encourages Young Women to Explore Scientific, Technical Careers
The U.S. Department of Energy's Argonne National Laboratory will host the 20th annual Science Careers in Search of Women conference, Thursday, March 8.
About 350 students from nearly 60 schools throughout the Chicago area will participate in the day-long conference, which aims to encourage high school women to consider careers in science and technology.
Science Careers in Search of Women puts students face-to-face with scientists in a variety of fields and provides an opportunity to spend a day interacting with positive female role models.
"Women are still under represented in scientific and engineering fields," says conference chairperson Cristina Negri, a researcher in Argonne's Energy Systems Division. "Having these young women meet with successful female scientists is an important way to show them that, contrary to gender stereotypes, this is a career path that is accessible to them." continue
