A new chemical analysis technique developed by a research group at the National Institute of Standards and Technology (NIST) uses the shifting ultrasonic pitch of a small quartz crystal to test the purity of only a few micrograms of material. …
Suspicious packages and powders have triggered more than 30,000 responses by U.S. law enforcement agencies across the country since 2001. These events are expensive, time-consuming and potentially dangerous. To help first responders at all levels of…
Researchers at the National Institute of Standards and Technology (NIST) have released an updated version of a computer system testing tool that can cut costs by more efficiently finding flaws. A tutorial on using the tool accompanies the new …
National Institute of Standards and Technology (NIST) researchers have developed new certified reference materials for measuring amounts of organic acids in dietary supplements formulated with Vaccinium berries — cranberries, blueberries and …
Extending its 26-year tradition of innovative quantum voltage standards, researchers at the National Institute of Standards and Technology (NIST) have begun shipping a new 10-volt standard to users around the world. The programmable system mea…
Taking the first steps of what would be a major historical advance in the science of measurement, the National Institute of Standards and Technology (NIST) is participating in a worldwide effort to recommend major revisions to the Internationa…
Recent puzzling observations of tiny variations in nuclear decay rates have led some to question the science of using decay rates to determine the relative ages of rocks and organic materials. Scientists from the National Institute of Standards and …
Researchers at the National Institute of Standards and Technology (NIST) are stepping up the pace for designing safer building evacuations by releasing large, numerical data sets that track the movement of people on stairs during high-rise building …
The National Institute of Standards and Technology (NIST) has issued its first Guidelines for Smart Grid Cyber Security, which includes high-level security requirements, a framework for assessing risks, an evaluation of privacy issues at personal re…
NIST will use the new ultra-dark detector, described in a new paper in Nano Letters,* to make precision laser power measurements for advanced technologies such as optical communications, laser-based manufacturing, solar energy conversion, and in…
Some people like peanut butter in sandwiches. Other people mix it in desserts or feed it to squirrels. Now there is a new use for peanut butter — as a quality assurance tool. The National Institute of Standards and Technology (NIST) recently issued Standard Reference Material (SRM) 2387, a peanut butter sample that has been characterized with state-of-the-art measurement methods to provide values for the amount of fat, protein, vitamins, minerals and other analytes it contains. It is one of a series of food-matrix SRMs that can be used by food manufacturers to validate production and quality control procedures as well as ensure accurate labeling of product content.
