Remote Detection of Electronic Devices

Non-Linear Junction Detection is a well-known technique for detecting electronics that utilize semiconductor (solid-state) junctions. The current state of the art for finding hidden electronics — such as electronic eavesdropping devices — using this technology has a maximum range of about 2 m, and more...

Researchers have found a versatile workaround to create chemical compounds that could prove useful for medical imaging and drug development. While studying chemical...

Terahertz radiation — the band of the electromagnetic spectrum between microwaves and visible light — has promising applications in medical and industrial imaging and chemical...

LLNL Finds Reason Behind Defects in 3D Printing

High-speed images of a common laser-based metal 3D printing process, coupled with newly updated computer models, have revealed the mechanisms behind material redistribution, a phenomenon that...

It's difficult to see the details of atomic and topographical changes that lead to battery failure. However a team of researchers developed a method to see reactions leading to...

NASA’s Marshall Space Flight Center is building a small CubeSat that uses an 85-m2 solar sail deployed from a central location to capture the push of photons...

In designing a hand-actuated microspine gripper, a ratcheting locking mechanism was required that had discrete points of locking engagement. The mechanism had to actuate...

Green Approach for Toughening Thermosetting Reactive Resins

Thermosetting reactive resin systems such as epoxy, bismaleimide, and polyimide classes of material are brittle. The origin of brittleness is attributed to the high crosslinking density that exists in the fully cured forms of these materials. Traditionally, the toughness of these resins...

Metamaterials with zero, or even negative refractive index for sound offer new possibilities for acoustic imaging and for the control of sound at sub-wavelength scales. The...

Cell Processing Cartridge for Miniature Cytometer

Portable flow cytometers, especially in handheld or briefcase sizes, have not been available. One reason is the need to support complex, high-pressure fluidics and process cells using a centrifuge and mixing device. A need existed for point-of-care and/or point-of-analysis flow cytometry.

Computers use different kinds of memory technologies to store data. Long-term memory — typically a hard disk or flash drive — needs to be dense in order to store as much data as...
