Predicting the limits of friction: Sandia looks at properties of material

ALBUQUERQUE, N.M. — Normally, bare metal sliding against bare metal is not a good thing. Friction will destroy pistons in an engine, for example, without lubrication. Sometimes, however, functions require metal on metal contact, such as in headphone jacks or electrical systems in wind turbines. Still, friction causes wear and wear destroys performance, and it’s […]

Guiding Light: Sandia creates 3-D metasurfaces with optical possibilities

ALBUQUERQUE, N.M. — Metamaterials don’t exist in nature, but their ability to make ultra-thin lenses and ultra-efficient cell phone antennas, bend light to keep satellites cooler and let photovoltaics absorb more energy mean they offer a world of possibilities. Formed by nanostructures that act as “atoms,” arranged on a substrate to alter light’s path in […]

Sandia using kinetics, not temperature, to make ceramic coatings

Room temperature coatings make design, fabrication flexible ALBUQUERQUE, N.M. — Researcher Pylin Sarobol explains an elegant process for ultrafine-grained ceramic coatings in a somewhat inelegant way: sub-micron particles splatting onto a surface. That splatting action is a key part of a Sandia National Laboratories project to lay down ceramic coatings kinetically. By making high-velocity submicron […]

Research at Sandia looking at how brittle materials fail

ALBUQUERQUE, N.M. — If you want to see what happens if your phone falls onto concrete, you can actually drop it or let an engineer work out the consequences in advance. Odds are you’ll go with the engineer. Figuring out how brittle materials inside a device behave, and fail, is one goal of Sandia National […]

Battling corrosion to keep solar panels humming

ALBUQUERQUE, N.M. — People think of corrosion as rust on cars or oxidation that blackens silver, but it also harms critical electronics and connections in solar panels, lowering the amount of electricity produced. “It’s challenging to predict and even more challenging to design ways to reduce it because it’s highly dependent on material and environmental […]

Honey, I shrunk the circuit

Sandia research could improve defense electronics, electric vehicles, electrical grids ALBUQUERQUE, N.M. — Sandia National Laboratories researchers have shown it’s possible to make transistors and diodes from advanced semiconductor materials that could perform much better than silicon, the workhorse of the modern electronics world. The breakthrough work takes a step toward more compact and efficient […]

Diamonds Aren’t Forever: Sandia, Harvard team create first quantum computer bridge

ALBUQUERQUE, N.M. — By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together. “People have already built small quantum computers,” says Sandia researcher Ryan Camacho. “Maybe the first useful […]

Materials society names Sandia metallurgist as fellow

ALBUQUERQUE, N.M. — Don Susan, a researcher in Sandia National Laboratories’ Metallurgy and Materials Joining organization, has been named a fellow of ASM International in recognition of distinguished contributions to materials science and engineering. The citation from the society said Susan received the honor, one of the highest in the field of materials, for “sustained […]

Supercomputers receive funding to help predict, modify new materials

ALBUQUERQUE, N.M. — The Department of Energy (DOE) will invest $16 million over the next four years in supercomputer technology that will accelerate the design of new materials by combining  theoretical and experimental efforts to create new validated codes. Sandia National Laboratories researcher Luke Shulenburger will head a team working to improve algorithms that predict […]

Blowing bubbles to catch carbon dioxide

Sandia, UNM develop bio-inspired liquid membrane that could make clean coal a reality ALBUQUERQUE, N.M. – Sandia National Laboratories and the University of New Mexico (UNM) have created a powerful new way to capture carbon dioxide from coal- and gas-fired electricity plants with a bubble-like membrane that harnesses the power of nature to reduce CO2 […]
