When testing composite structures, it is important to understand the response of the structure to the load. Of significance is the formation of damage and growth of that damage leading...

Crew time on the International Space Station (ISS) is extremely limited for any operations on science payloads. Autonomous science experiments in small, self-contained, cubical payloads are highly desirable...

Correlation spectroscopy is an attractive technique for sensing and analysis applications because it combines the attributes of mechanical and optical simplicity, high selectivity, and good sensitivity. In...

This column presents technologies that have applications in commercial areas, possibly creating the products of tomorrow. To learn more about each technology, see the contact information provided for that...

Thinning a material down to a single-atom thickness can dramatically change that material’s physical properties. Graphene, the best known two-dimensional (2D) material, has...

Assembly Pins

JW Winco, New Berlin, WI, offers GN 2342 RoHS-compliant stainless steel assembly pins with three washer types available that place the bolt in an axial position in its insertion direction....

For decades, mass spectrometers have offered a relatively fast and highly sensitive way to analyze and detect chemical compounds. But their bulky size has been a hindrance, limiting the in-field potential of the...

Piezoelectric materials, which generate an electric current when compressed or stretched, are familiar and widely used; for example, lighters that spark when a switch is...

Much can be detected in blood or urine — viral illnesses, metabolic disorders, or autoimmune diseases can be diagnosed with laboratory tests, for instance. But such examinations often take a few...

Laser engineers are leveraging new materials, unusual gain mechanisms, and innovative cavity designs to push laser performance into new regimes. Pulse lengths are getting...

Digital microscopes are being automated and computerized to make them easier to use, display more data with more detail and precision, and expand their areas of application. With traditional...
