Developments in ultra-narrow manufacturing capabilities enable transformative, world-changing, technology. Read on to learn how boundaries are being pushed.
Briefs: Medical
Researchers have developed a method to detect bacteria, toxins, and dangerous chemicals in the environment with a biopolymer sensor that can be printed like ink on a wide range of materials — including wearables. Read on to learn more.
Briefs: Photonics/Optics
Researchers have developed standards and calibrations for optical microscopes that allow quantum dots to be aligned with the center of a photonic component to within an error of 10 to 20 nanometers (about one-thousandth the thickness of a sheet of paper). Such alignment is critical for chip-scale devices that employ the radiation emitted by quantum dots to store and transmit quantum information. Read on to learn more.

Because they can go where humans can’t, robots are especially suited for safely working with hazardous nuclear waste. Now, scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have designed and tested a remote-controlled, dual-arm telerobotics system with human-like capabilities that has the potential to revolutionize hazardous waste clean-up and holds potential for broader applications.

Detector can identify radioactive isotopes with high resolution.
Briefs: Materials
An international team of researchers reports on a compact high-brightness mid-IR-driven source combining a gas-filled anti-resonant-ring photonic crystal fiber with a novel nonlinear-crystal. The tabletop source provides a seven-octave coherent spectrum from 340 nm–40,000 nm with spectral brightness 2–5 orders of magnitude higher than one of the brightest synchrotron facilities.
Briefs: Manufacturing & Prototyping
Recent experiments by a team from the West Virginia University focused on how a weightless microgravity environment affects 3D printing using titania foam, a material with potential applications ranging from UV blocking to water purification. ACS Applied Materials and Interfaces published their findings.
Briefs: Imaging
Imagine being able to snap a picture of extremely fast events on the order of a picosecond.
Briefs: RF & Microwave Electronics
Most space satellites are powered by photovoltaic cells that convert sunlight to electricity. Exposure to certain orbit radiation can damage the devices. Scientists have proposed a radiation-tolerant photovoltaic cell design that features an ultrathin layer of light-absorbing material.
Briefs: Lighting
A wavelength of visible light is about 1,000 times larger than an electron, so the way the two affect each other is limited by that disparity. Now, researchers have come up with a way to make...

Computer-Implemented Energy Depletion Radiation Shielding
Radiation shielding for space as well as some terrestrial applications is challenging due to the wide variety and energy ranges of radiation particles.
NASA Spinoff: Medical
Inspired by NASA’s research of certain segments of DNA to estimate radiation damage, Promega Corp. used the technique to create its own diagnostic test which is used to customize cancer treatment.
Briefs: Materials
This invention is a method of removing or adsorbing a target substance or material.
Briefs: Materials
Tests showed the metalens they made could focus its 197-nanometer output onto a spot measuring 1.7 microns in diameter, increasing the power density of the light output by 21 times.
Briefs: Photonics/Optics
A terahertz laser was developed with high constant power, tight beam pattern, and broad electric frequency tuning for a wide range of applications in chemical sensing and imaging. The optimized...
