Pulsed laser vaporization (PLV) production of single-wall carbon nanotubes (SWNTs) on traditional Co/Ni catalyst was explored with respect...
Briefs: Materials
For many highly stressed engineering applications like bearings and gears, contaminated steel parts can lead to devastating outcomes such as an emergency shutdown or the end of a mission. Ensuring that these critical...
Briefs: Communications
Infrared motion detectors can cover only a limited amount of space, a person has to be within the detector's line of sight to be detected, and lights can go off when a person remains still...

Lamina emergent compliant mechanisms (including origami-adapted compliant mechanisms) are mechanical devices that can be fabricated from a planar material (a lamina) and have motion that...
Briefs: Sensors/Data Acquisition
Painting of surfaces having numerous facets and/or curved surfaces is a time-consuming process that requires the application of several coats (layers) of paint. Such surfaces are often found on...
Briefs: Materials
3D printing allows for the efficient manufacture of complex geometries. A very promising method is direct laser writing in which a computer-controlled focused laser beam acts as a pen and produces the desired...
Briefs: Motion Control
Gyroscopes are devices that help vehicles, drones, and wearable and handheld electronic devices know their orientation in three-dimensional space. Originally, gyroscopes were sets of nested wheels, each spinning on a...
