Non-Destructive Additive Manufacturing Characterization Coupon
Additive manufacturing (AM) material assurance has relied upon traditional test coupons and testing methods that work well for wrought materials, but fail to address the unique and not as well-known characteristics of AM parts. A new standardized, integrated test coupon was designed...

Joining of Ti, Mo, and Ni Terminated Thermoelectric Segments via Brazing
The joining of low- and high-temperature thermoelectric materials (with ZT optimized to specific temperature ranges) to each other in a segmented configuration can lead to enhanced device efficiency. The resulting joints between these materials must be both chemically and...
Briefs: Electronics & Computers
Engineers have invented a new architecture for quantum computing based on novel “flip-flop” qubits. The new chip design allows for a silicon quantum processor that can be scaled...
Briefs: Robotics, Automation & Control
A software system was developed that helps robots more effectively act on spoken instructions — no matter how abstract or specific those instructions may be — from people who by...

Process Turns Carbon Dioxide into 3D Graphene with Microporous Surface
The conversion of carbon dioxide to useful materials usually requires high energy input due to its ultrahigh stability. A heat-releasing reaction between carbon dioxide and sodium was developed to take carbon dioxide and turn it into 3D graphene with micropores across its...
Briefs: Software
From phone camera snapshots to life-saving medical scans, digital images play an important role in the way humans communicate information. But digital images are subject to a range of...
Briefs: Manufacturing & Prototyping
As 3D printing has become a mainstream technology, studies have investigated printable structures that will fold themselves into useful three-dimensional shapes when heated or...

Dual-Field-of-View Multiband Optics
Multi-spectral-band systems are steadily emerging as a desired feature in a camera system. Each spectral band offers different image characteristics. Shorter-wavelength spectral bands provide the potential for better resolution due to the smaller impact of diffraction on the size of the optics blur. This means...
Briefs: Motion Control
Researchers at the Ecole Polytechnique Federale de Lausanne (EPFL) have created the first functional robot powered entirely by vacuum. It is made of soft building blocks that move by having air sucked out...
Briefs: Motion Control
An engineering team at the University of California San Diego has designed and built a gripper that can pick up and manipulate objects without needing to see them and without being...
