RTM370 imide resin was developed to address the limitations of conventional imide resins, which are generated from commercially available symmetrical biphenyl dianhydride...
Briefs: Manufacturing & Prototyping
When a coffee mug leaves a ring, the outer edges of that ring are darker than the inside of the ring. That's because the solute is separated from the liquid during the...
Briefs: Motion Control
Researchers have created a two-dimensional, shape-changing sheet that moves autonomously in a reactant-filled fluid. The integrated system utilizes a chemical reaction to activate the fluid...
Briefs: Sensors/Data Acquisition
Jet engines can have up to 25,000 individual parts, making regular maintenance a tedious task that can take more than a month per engine. Many components are located deep inside...
Briefs: Medical
A novel foot-pedal-operated system and device were developed to control translational and rotational movement of an object in three-dimensional (3D) space. The Foot Pedal Controller system enables operators to control...
Briefs: Robotics, Automation & Control
Hundreds of small robots can work in a team to create biology-inspired shapes without an underlying master plan, purely based on local communication and movement. To achieve this, the biological principles...
Briefs: Motion Control
For patients missing a hand, one of the biggest challenges to regaining a high level of function is the inability to rotate one's wrist (pronate and supinate). These are essential movements...
Briefs: Photonics/Optics
Researchers at Dartmouth have found a way to make back surgery safer, faster, and more cost effective. MRIs and CT scans can help surgeons identify spine problems such as...
Briefs: Materials
Engineers at Duke University have developed a way to extract a sequence of images from light scattered through a mostly opaque material — or even off a wall — from one long...
Briefs: Sensors/Data Acquisition
A new method of X-ray scanning will allow for the visualization of many more biological molecules, providing critical information about what is inside molecules to scientists who...
Briefs: Nanotechnology
Light of different colors travels at different speeds in different materials and structures. This is why we see white light split into its constituent colors after refracting through a...
Briefs: Sensors/Data Acquisition
Ultrashort optical pulses are becoming more and more relevant in a number of applications including distance measurement, molecular fingerprinting and ultrafast sampling. Many...
Briefs: Sensors/Data Acquisition
Researchers have developed a new ultrasound transducer that could dramatically lower the cost of ultrasound scanners to as little as $100. Conventional ultrasound scanners use piezoelectric crystals to...
