The quest for longer-lasting solar cells

An Argonne researcher is collaborating with a user of the laboratory’s Center for Nanoscale Materials to study what makes silicon solar cells degrade. The answers may help lead to more durable solar cells and more affordable solar power.

This shows the study’s crossbar array design — vertical and horizontal electrodes with red memory cells where they intersect. “Flying out” of a single memory cell is a model of its molecular structure with tin (gold sphere) diffusing through the insulating HfO<sub>2</sub> layer (blue and white matrix). Each component is essential in forming the filament across the metal-insulator-metal stack in this resistive switching architecture. (Image by Argonne National Laboratory.)
Tin type

Argonne researchers find that tin is a silicon-friendly alternative for production of solid-state memory components.

Oleo Sponge can be wrung out, the oil collected, and the material reused — it has stood up to dozens of cycles so far without exhibiting any degradation in performance. (Image by Argonne National Laboratory; click to view larger.)
Argonne seeks partners to commercialize Oleo Sponge technology

The U.S. Department of Energy’s (DOE’s) Argonne National Laboratory seeks partners to commercialize the Oleo Sponge, its award-winning, patent pending oil-sorbent technology.

Electrons in some oxides can experience an “unconventional slowing down” of their response to a light pulse, according to Argonne material scientists and their collaborators. This surprising behavior may result in useful properties related to magnetism, conductivity or even superconductivity. (Image by Argonne National Laboratory.)
Electrons slowing down at critical moments

Argonne scientists have determined that electrons in some oxides can experience an “unconventional slowing down” of their response to a light pulse. This behavior may result in potentially useful properties related to magnetism, conductivity or even superconductivity.

Argonne welcomes The Martian author Andy Weir

Best-selling science fiction author Andy Weir visited Argonne to give a series of standing-room-only talks, inspiring students and scientists alike.

Argonne nanoscientist Xiao-Min Lin works with the shear cell device that enabled the new discovery in shear-thickening fluids. The polycarbonate cell holds the nanoparticle suspension and the mechanical response of the fluid is measured by the transducer in the rheometer above. The X-ray beam is focused on the sample from the left. (Image by Argonne National Laboratory.)
Through thick and thin

Researchers solve a decades-old question: Is particle ordering responsible for the thickening of some industrial products when stirred rapidly? The answer brings us one step closer to solving complex industrial production problems.

This shows a strand of magnetic molecules atop a dense bed of “armchair” graphene nanoribbons — which appear as a series of closely spaced strings — grown on a gold crystal surface. The image was taken on a low-temperature scanning tunneling microscopy tool at Argonne’s <a href="http://www.anl.gov/cnm/user-information/call-proposals">Center for Nanoscale Materials</a>.

Opening windows for new spintronic studies

A surprising discovery could potentially offer major advantages in speed, heat dissipation and power consumption in electronic devices.

IME scientists dig deep in soil for data to improve agriculture, pollution

Soil is incredibly complex — full of organisms, microbes and chemicals that move and change constantly — and it all feeds into crop health and the Earth’s nutrient cycles in ways that aren’t fully understood. Recent advances in wireless data communications and the growing revolution of portable, cheap sensors have made it possible for scientists, including Profs. Monisha Ghosh and Supratik Guha, to start a pilot program to take real-time soil measurements.

Nine ways Argonne advanced science and technology in 2017

As 2018 approaches, Argonne looks back at nine cool stories that came out of research projects and collaborations at the laboratory.

The figure in the foreground shows near-infrared and broadband light pulses (squiggly lines at top) striking a silver nanocube measuring 150 nanometers square. The near-infrared pulse excites electrons in the nanostructure, while the broadband pulse monitors their optical response. An aluminum oxide spacer separates the nanocube from a gold film with a thickness of 50 nanometers. The spacer measures between 1 and 25 nanometers thick. A water molecule, by comparison, is approximately 1.5 nanometers in diameter. (Image courtesy of Matthew Sykes, Argonne National Laboratory, Shutterstock / Triff and Shutterstock / siro46.)
‘Hot’ electrons heat up solar energy research

Argonne research has shown how hybrid nanomaterials may be used to convert light energy more efficiently for applications in photocatalysis, photovoltaics and ultrafast optics.
