Egyptian blue, derived from calcium copper silicate, was routinely used on ancient depictions of gods and royalty. Previous studies have shown that when Egyptian blue absorbs visible light, it then...

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...

Researchers funded by the National Institute of Biomedical Imaging and Bioengineering (NIBIB) have developed a non-invasive imaging technique that accurately detects skin cancer...

Pulsed laser vaporization (PLV) production of single-wall carbon nanotubes (SWNTs) on traditional Co/Ni catalyst was explored with...

Innovators at NASA's Glenn Research Center have expanded their growing portfolio of aerogels to include a new optically transparent polyimide aerogel. Aerogels — low-density, highly porous,...

A technique was developed that uses a specially adapted 3D printer to build therapeutic biomaterials from multiple materials. The advance could be a step toward on-demand printing of complex...

The first laser based on the wave physics phenomenon called bound states in the continuum (BIC) has been developed. The technology could revolutionize the development of surface...

It is relatively easy to measure small movements of large objects, but is much more difficult when the moving parts are on the scale of nanometers, or billionths of a meter. The ability to accurately...

Spectrometers are widely used for applications such as chemical analysis, remote sensing, quality control, environmental monitoring, spaceborne measurements, and optical measurements. Most spectrometers...

NASA Langley Research Center has developed a novel optical grating device that dynamically modulates light and is capable of controlling the spectral properties and propagation of light...

Today's photovoltaic power systems are generally comprised of a single photovoltaic module or multiple modules connected by combinations of series and parallel circuits as a photovoltaic array....

There are challenges involved when using magnetically responsive materials to achieve the one-way flow of light in a photonic chip, including the ability to place compact magnets on a chip. In...

Ames Laboratory is a government-owned, contractor-operated national laboratory of the U.S. Department of Energy (DOE), operated by and located on the campus of Iowa State University in Ames, IA. For more than...

The detection and localization of gas releases, such as methane from leaking natural gas pipelines or nitrogen oxides from failing electrical equipment, require high sensitivity to the target gas and insensitivity...

Most naturally occurring materials have a disordered atomic structure that interferes with the propagation of both sound and electromagnetic waves. When the waves come into contact with these...

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...

A process has been developed that enables the production of a 2-mm flat camera. The lens is partitioned into 135 tiny facets, similar to the eyes of an insect. The facetVISION camera is...

A blue-light imaging method was developed that can be used to obtain visual data from large test fires where high temperatures could disable or destroy conventional electrical and mechanical sensors. The...

A team of researchers at Washington University in St. Louis was the first to successfully record environmental data using a wireless photonic sensor resonator with a...
