eMpulse Test Systems’ four-poster road simulator uses servo-electric actuators to simulate road and driving conditions.
Since the early 1980s, the automotive industry has used hydraulically actuated (servo-hydraulic) test systems to simulate operating speeds and road conditions for testing OEM components and fully assembled vehicles.

Artificial intelligence (AI) is gaining momentum across a vast array of fields. Nearly everyone has tried or actively uses a form of AI, whether for personal or professional purposes.

Every time you squeeze toothpaste onto your toothbrush, spray perfume on your skin, or swallow a pill, you’re using the result of a carefully crafted recipe made in a lab. These are called formulations.

In last month’s article, “ANOVA and the Process Behavior Chart,” we saw how both techniques use the same basic comparison to answer completely d
By monitoring how giant Rydberg atoms interact with heat in their environment, Noah Schlossberger and colleagues can measure temperature with remarkable accuracy. Credit: R. Jacobson/NIST
Scientists at the National Institute of Standards and Technology (NIST) have created a new thermometer using atoms boosted to such high energy levels that they are 1,000 times larger than normal.
Without us realizing it, metrology and its associated standards and services play a big role

It creates a warm and inviting atmosphere. Its natural grain and color tones have a lively effect and add character to a room. We are talking about classic wood flooring—usually laminate, and optionally with a click system for easy installation.
In his lab at MIT, Zachary Smith is designing membranes with tiny pores that can filter tiny molecules based on their size. Here, Smith holds a “membrane coupon,” which is a small piece of polymer that can filter gas molecules selectively.
For many industrial processes, the typical way to separate gases, liquids, or ions is with heat, using slight differences in boiling points to purify mixtures. These thermal processes account for roughly 10% of the energy use in the United States.

On June 18, 2023, the Titan submersible was about 90 minutes into its two-hour descent to the Titanic wreckage at the bottom of the Atlantic Ocean when it lost contact with its support ship.
Right now, the U.S. and Germany have different approaches to defining, or realizing, as the researchers call it, the kilogram. Here, NIST researcher Darine Haddad looks on as German researcher Beatrice Rodiek places a sphere on NIST’s highly accurate weighing machine, known as the Kibble balance. The goal of the research is to get closer to the same definition using the different methods. Credit: B. Hayes/NIST
NIST is unique as the national measurement science institute. We are the U.S. agency responsible for maintaining measurement standards, from the second to the kilogram.
