Nanoparticle gel unites oil and water in manufacturing-friendly approach

Novel gel-creation method could open applications in water filtration, other applications

15-Feb-2021

Oil and water may not mix, but adding the right nanoparticles to the recipe can convert these two immiscible fluids into an exotic gel with uses ranging from batteries to water filters to tint-changing smart windows. A new approach to creating this unusual class of soft materials could carry them ...

Room Temperature Conversion of CO₂ to CO: A New Way to Synthesize Hydrocarbons

New method could potentially reduce dioxide emission into the atmosphere and slash costs of chemical manufacturing

04-Nov-2020

Researchers at the National Institute of Standards and Technology (NIST) and their colleagues have demonstrated a room-temperature method that could significantly reduce carbon dioxide levels in fossil-fuel power plant exhaust, one of the main sources of carbon emissions in the ...

NIST Study Identifies Chemical Blends as Possible Alternative Refrigerants

31-May-2019

More than a dozen chemical blends could serve as alternative refrigerants that won’t heat the atmosphere as much as today’s refrigerants do, or catch fire, according to a new computational study by the National Institute of Standards and Technology (NIST). The NIST study identified the 22 “best” ...

Researchers boost intensity of nanowire LEDs

26-Mar-2019

Nanowire gurus at the National Institute of Standards and Technology (NIST) have made ultraviolet light-emitting diodes (LEDs) that, thanks to a special type of shell, produce five times higher light intensity than do comparable LEDs based on a simpler shell design. Ultraviolet LEDs are used in a ...

Simulations Suggest Graphene Can Stretch to Be a Tunable Ion Filter

28-Nov-2018

Researchers at the National Institute of Standards and Technology (NIST) have conducted simulations suggesting that graphene, in addition to its many other useful features, can be modified with special pores to act as a tunable filter or strainer for ions (charged atoms) in a liquid. The concept, ...

Making plastic production more energy efficient - with MOFs

30-Oct-2018

An innovative filtering material may soon reduce the environmental cost of manufacturing plastic. Created by a team including scientists at the National Institute of Standards and Technology (NIST), the advance can extract the key ingredient in the most common form of plastic from a mixture of ...

A new way to measure nearly nothing

Prototype design uses ultracold trapped atoms to measure pressure

23-Oct-2018

Many semiconductor fabricators and research labs are under increasing pressure from, of all things, vacuum. These facilities need to remove greater amounts of gas molecules and particles from their setups as new technologies and processes demand lower and lower pressures. For example, the vacuum ...

New method measures 3D polymer processing precisely

11-Oct-2018

Recipes for three-dimensional (3D) printing, or additive manufacturing, of parts have required as much guesswork as science. Until now. Resins and other materials that react under light to form polymers, or long chains of molecules, are attractive for 3D printing of parts ranging from ...

Scratching more than the surface of auto coatings

Improved tests go "deeper"

24-Sep-2018

Know that sickening feeling when you exit the grocery store and find your car has been banged up by a runaway shopping cart? It may one day be just a bad memory if auto body manufacturers make use of a new suite of tests developed by the National Institute of Standards and Technology (NIST) and ...

A novel graphene quantum dot structure takes the cake

27-Aug-2018

In a marriage of quantum science and solid-state physics, researchers at the National Institute of Standards and Technology (NIST) have used magnetic fields to confine groups of electrons to a series of concentric rings within graphene, a single layer of tightly packed carbon atoms. This tiered ...
