Traps. Whether you’re squaring off against the Empire or trying to wring electricity out of sunlight, they’re almost never a good thing. But sometimes you can turn that trap to your advantage. A team from the Univ. of Nebraska-Lincoln, working with researchers at NIST, has shown that electron-trapping defects that are typically problematic in solar cells can be an asset when engineering sensitive light detectors.
After devising several new and promising "green" flame retardants for furniture padding, NIST researchers took a trip to the grocery store and cooked up their best fire-resistant coatings yet. As important, these protective coatings can be made in one straightforward step.
NIST researchers have demonstrated the most precise method yet to measure the structural configuration of monoclonal antibodies, an important factor in determining the safety and efficacy of these biomolecules as medicines. Monoclonal antibodies are proteins manufactured in the laboratory that can target specific disease cells or antigens (proteins that trigger an immune reaction) for removal from the body.
Additive manufacturing has been called a game changer. But new games require new instructions, and the manuals for a growing assortment of methods for building parts and products layer-by-layer, collectively known as "3D printing", still are works in progress. Manufacturing researchers at NIST have scoped out the missing sections in current guidelines for powder bed fusion, the chief method for "printing" metal parts.
If you're designing a new computer, you want it to solve problems as fast as possible. Just how fast is possible is an open question when it comes to quantum computers, but physicists at NIST have narrowed the theoretical limits for where that "speed limit" is. The research implies that quantum processors will work more slowly than some research has suggested.
The name sounds like something Marvin the Martian might have built, but the “nanomechanical plasmonic phase modulator” is not a doomsday device. Developed by a team of government and university researchers, including physicists from NIST, the innovation harnesses tiny electron waves called plasmons. It’s a step towards enabling computers to process information hundreds of times faster than today’s machines.
Scientists working at NIST and the NIH have devised and demonstrated a new, shape-shifting probe, about one-hundredth as wide as a human hair, which is capable of sensitive, high-resolution remote biological sensing that is not possible with current technology. If eventually put into widespread use, the design could have a major impact on research in medicine, chemistry, biology and engineering.
Our fast-approaching future of driverless cars and “smart” electrical grids will depend on billions of linked devices making decisions and communicating with split-second precision to prevent highway collisions and power outages. But a new report released by NIST warns that this future could be stalled by our lack of effective methods to marry computers and networks with timing systems.
Criminal justice, cosmology and computer manufacturing may not look to have much in common, but these and many other disparate fields all depend on sensitive measurements of x-rays. Scientists at NIST have developed a new method to reduce uncertainty in x-ray wavelength measurement that could provide improvements awaited for decades.
Smartphones and tablets are everywhere, which is great for communications but a growing burden on wireless channels. Forecasted huge increases in mobile data traffic call for exponentially more channel capacity. Boosting bandwidth and capacity could speed downloads, improve service quality and enable new applications like the Internet of Things connecting a multitude of devices.
While the mysterious, unseen forces magnets project are now (mostly) well understood, they can still occasionally surprise us. For instance, thin films of cobalt have been observed to spontaneously switch their poles: something that typically doesn’t happen in the absence of an external magnetic field. Physicists at NIST and the Univ. of Maryland have measured this phenomenon on the largest scale yet.
A little detective work by nuclear physicists has uncovered hidden uncertainties in a popular method for precisely measuring radioactive nuclides, often used to make reference materials for forensic analyses such as radioactive dating. The much-used method, called α/β-γ anticoincidence counting, has long relied on simplified assumptions. Now researchers from NIST have produced a more realistic model.
To understand diseases like Parkinson’s, the tiniest of puzzles may hold big answers. That’s why a team including scientists from NIST have determined how two potentially key pieces of the Parkinson’s puzzle fit together, in an effort to reveal how the still poorly understood illness develops and affects its victims.
Scientists have demonstrated a nanoscale memory technology for superconducting computing that could hasten the advent of an urgently awaited, low-energy alternative to power-hungry conventional data centers and supercomputers. In recent years, the stupendous and growing data demands of cloud computing, expanded Internet use, mobile device support and other applications have prompted the creation of large, centralized computing facilities.
NIST scientists have developed a novel method to rapidly and accurately calibrate gas flow meters, such as those used to measure natural gas flowing in pipelines, by applying a fundamental physical principle: When a sound wave travels through a gas containing temperature gradients, the sound wave's average speed is determined by the average temperature of the gas.
Just because concrete is the most widely used building material in human history doesn’t mean it can’t be improved. A recent study conducted by researchers from NIST, the Univ. of Strasbourg and Sika Corp. using U.S. Dept. of Energy Office of Science supercomputers has led to a new way to predict concrete’s flow properties from simple measurements.
A new insight into the fundamental mechanics of the movement of molecules recently published by researchers at NIST offers a surprising view of what happens when you pour a liquid out of a cup. More important, it provides a theoretical foundation for a molecular-level process that must be controlled to ensure the stability of important protein-based drugs at room temperature.
Spotting molecule-sized features may become both easier and more accurate with a sensor developed at NIST. With their new design, NIST scientists may have found a way to sidestep some of the problems in calibrating atomic force microscopes (AFMs). The AFM is one of the main scientific workhorses of the nano age.
Earlier this month, the NTSB released its Aircraft Incident Report on a fire aboard a Japan Airlines Boeing 787, concluding that the fire was probably caused by an internal short circuit within a cell of the lithium-ion battery.
Defect-free nanowires with diameters in the range of 100 nm hold significant promise for numerous in-demand applications. That promise can't be realized, however, unless the wires can be fabricated in large uniform arrays using methods compatible with high-volume manufacture. To date, that has not been possible for arbitrary spacings in ultra-high vacuum growth.
Radio frequency identification (RFID) tags have become increasingly popular for tracking everything from automobiles being manufactured on an assembly line to zoo animals in transit to their new homes. Now, thanks to a new NIST report, the next beneficiaries of RFID technology may soon be law enforcement agencies responsible for the management of forensic evidence.
An ultra-stable, ultra-thin bonding technology has been adapted by researchers for use as a super-strong vacuum seal. Though it is less than 100 nm thick, the bond can withstand pressure up to 2 megapascals, and its drift, or how much it shifts over time, is on the order of less than 3 trillionths of a meter per hour.
Single-walled carbon nanotubes are loaded with desirable properties. In particular, the ability to conduct electricity at high rates of speed makes them attractive for use as nanoscale transistors. But this and other properties are largely dependent on their structure, and their structure is determined when the nanotube is just beginning to form.
Truth shines a light into dark places. But sometimes to find that truth in the first place, it’s better to stay in the dark. That’s what recent findings at NIST show about methods for testing the safety of nanoparticles. It turns out that previous tests indicating that some nanoparticles can damage our DNA may have been skewed by inadvertent light exposure in the lab.
The push for more efficient air conditioners and heat pumps aims to trim the 30% share of residential electrical energy use devoted to cooling and heating. But the benefits of improved energy-efficiency ratings can go for naught if the equipment is not installed properly, as verified in a recent study from NIST.
