NIST develops test method for key micromechanical property

01-09-2008 · EurekAlert!

Engineers and researchers designing and building new microelectromechanical systems can benefit from a new test method developed at the National Institute of Standards and Technology to measure a key mechanical property of such systems: elasticity. The new method determines the "Young's modulus" of thin films not only for MEMS devices but also for semiconductor devices in integrated circuits.

  1. NIST develops rapid method for judging nanotube purity
    02-01-2007 · EurekAlert!
    Researchers at NIST have developed a sensitive new method for rapidly assessing the quality of carbon nanotubes. Initial feasibility tests show that the method not only is faster than the standard analytic technique, but also effectively screens much smaller samples for purity and consistency and better detects sample variability.

  2. Smithsonian researchers develop models to assess wetland health
    09-14-2007 · EurekAlert!
    In a special issue of the journal Wetlands, Smithsonian scientists report a promising method of wetland assessment that will help environmental managers quickly take stock of wetlands across an entire watershed. Tools for this kind of rapid watershed-scale assessment -- relying on a few easily measurable key factors -- have been previously unavailable to managers.

    02-14-2007 · EurekAlert!
    The most important genes associated with a risk of developing type-2 diabetes have been identified, scientists report today in a new study. The research, published online in Nature, is the first time the genetic makeup of any disease has been mapped in such detail. It should enable scientists to develop a genetic test to show an individual their likelihood of developing diabetes mellitus type 2, commonly known as type-2 diabetes.

  6. Clock comparison yields clues to 'constant' change
    02-15-2007 · EurekAlert!
    Years of comparisons among the world's best atomic clocks -- based on different atoms -- have established the most precise limits ever achieved in the laboratory for detecting possible changes in so-called 'constants' of nature. The comparisons at NIST may help scientists test the latest theories in physics and develop a more complete understanding of the history of the universe.

  7. Key Function Of Nervous System Enzyme Found; Impact On Drug Development Against Alzheimer's
    09-29-2006 · ScienceDaily
    Ever since scientists first elucidated the molecular mechanisms underlying the pathology and loss of nerve cells in Alzheimer's disease, drug companies have been working to develop drugs which will inhibit the outbreak of this severe form of dementia. Now researchers in Munich and Berlin (Germany) have discovered that an enyzme which has a central causal role in Alzheimer's disease happens also to have a key function in the normal development of the nervous system. This enzyme, beta-secretase or BACE1, ensures that nerve fibers (axons) are adequately isolated with sheaths of myelin, enabling rapid conduction of electrical impulses, as well as preventing short-circuits, akin to plastic insulation on electrical wires.

  8. New study to test Statin-Parkinson's link
    01-15-2007 · EurekAlert!
    Results of a recent study linking low LDL cholesterol to Parkinson's provide the strongest evidence to date that it could be real, because statins work by reducing LDL cholesterol. The study by researchers at University of North Carolina showed that patients with low levels of LDL cholesterol are more than three and a half times more likely to develop Parkinson's disease than those with higher LDL levels.
