Argonne’s TechConnect hat trick

Argonne National Laboratory nanoscientist Anirudha Sumant has earned a TechConnect Innovation Award for the third year in a row. The award recognizes Sumant’s work on nitrogen-incorporated ultrananocrystalline diamonds for application as a portable electron source in field emission cathodes. The technology was developed in partnership with Euclid Techlabs to create a superior field emission electron source for use in linear accelerators.

Nanodiamonds are forever

Argonne researchers have created a self-generating, very-low-friction dry lubricant that lasts so long it could almost be confused with forever.

APS-CNM Users Meeting helps scientists plan for an even brighter future

The Advanced Photon Source and Center for Nanoscale Materials will host the APS-CNM Users Meeting to be held at Argonne from May 7 to 10.

Out of thin air

Argonne researchers conducted basic science computational studies as part of a collaboration with researchers at the University of Illinois at Chicago to design a “beyond-lithium-ion” battery cell that operates by running on air over many charge and discharge cycles. The design offers energy storage capacity about three times that of a lithium-ion battery, with significant potential for further improvements.

Argonne and Brookhaven researchers observed two kinds of defects forming in individual nanowires, depicted here. These nanowires are smaller in diameter than a human hair. (Image by Megan Hill/Northwestern University.)
Scientists have a new way to gauge the growth of nanowires

In a new study, researchers from the U.S. Department of Energy’s Argonne and Brookhaven National Laboratories observed the formation of two kinds of defects in individual nanowires, which are smaller in diameter than a human hair.

A marriage of light-manipulation technologies

Researchers from Argonne and Harvard University built a metasurface-based lens atop a Micro-Electro-Mechanical System (MEMS) platform. The result is a new, infrared light-focusing system that combines the best features of both technologies while reducing the size of the optical system.

Department of Energy awards flow into Argonne

DOE Secretary Rick Perry awarded Argonne with nearly $4.7 million in projects as part of the DOE’s Office of Technology Transition’s Technology Commercialization Fund (TCF) in September.

This shows the synthetic purple membrane assembly developed by Elena Rozhkova and fellow Argonne researchers. The assembly, which includes nanodiscs, titanium dioxide and platinum nanoparticles, can transform sunlight into hydrogen fuel. (Image by Argonne National Laboratory.)
Purple power: Synthetic ‘purple membranes’ transform sunlight to hydrogen fuel

Argonne researchers have found a new way to produce solar fuels by developing “synthetic purple membranes.” These membranes involve an assembly of lipid nanodiscs, man-made proteins, and semiconducting nanoparticles that, when taken together, can transform sunlight into hydrogen fuel.

“When scientists add or remove a proton (H+) from the perovskite (SmNiO3 (SNO)) lattice, the material’s atomic structure expands or contracts dramatically to accommodate it in a process called ‘lattice breathing,’” said Badri Narayanan, an Argonne assistant material scientist and co-author of the study. But when it happens repeatedly, this activity wanes, resembling human forgetfulness. (Image by Argonne National Laboratory.)
Forget about it

Inspired by human forgetfulness — how our brains discard unnecessary data to make room for new information — scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory, in collaboration with Brookhaven National Laboratory and three universities, conducted a recent study that combined supercomputer simulation and X-ray characterization of a material that gradually “forgets.” This could one day be used for advanced bio-inspired computing.
