Molecules have an orientation, and scientists have a new way to measure it
Molecular orientation is key to designing better materials
12-Dec-2022
In some materials, the molecules line up in a regular, repeating pattern. In others, they all point in random directions. But in many advanced materials used in medicine, computer chip manufacturing and other industries, the molecules arrange themselves in complex patterns that dictate the ...
New quantum material discovered
A research team came across a surprising form of "quantum criticality". This could lead to a design concept for new materials
26-May-2021
In everyday life, phase transitions usually have to do with temperature changes – for example, when an ice cube gets warmer and melts. But there are also different kinds of phase transitions, depending on other parameters such as magnetic field. In order to understand the quantum properties of ...
Crystalline supermirrors for trace gas detection in environmental science and medicine
Analysis of particularly complex gas mixtures with unprecedented accuracy
25-May-2021
In an international cooperation with partners from industry and research, physicists from the University of Vienna, together with Thorlabs, the National Institute of Standards and Technology (NIST), and the University of Kansas, have now succeeded for the first time in demonstrating ...
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 ...
