Argonne researcher Yuelin Li holds a sample holder containing a single gold nanorod in water. Li and colleagues discovered that nanorods melt in three distinct phases when grouped in large ensembles. Their research will inform the creation of next-generation technologies such as water purification systems, battery materials and cancer research. Photo by Mark Lopez/Argonne National Laboratory.

Shape-shifting groups of nanorods release heat differently

Researchers at Argonne have revealed previously unobserved behaviors that show how the transfer of heat at the nanoscale causes nanoparticles to change shape in groups.

Argonne researchers produce trace amounts of hydrogen with visible light by merging light-collecting proteins from a single-celled organism with a graphene platform. Both graphene and protein absorb the light and re-direct electrons towards the titanium dioxide. Electrons interact with protons at the site of the platinum nanoparticles to produce hydrogen.

A nanosized hydrogen generator

Researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have created a small scale “hydrogen generator” that uses light and a two-dimensional graphene platform to boost production of the hard-to-make element.

New nanotech invention improves effectiveness of the 'penicillin of cancer'

By combining magnetic nanoparticles with one of the most common and effective chemotherapy drugs, Argonne researchers have created a way to deliver anti-cancer drugs directly into the nucleus of cancer cells.

Silicene: To be or not to be?

A recent study at Argonne National Laboratory has called into question the existence of silicene, thought to be one of the world’s newest and hottest two-dimensional nanomaterials. The study may have great implications to a multi-billion dollar electronics industry that seeks to revolutionize technology at scales 80,000 times smaller than the human hair.

Argonne materials scientist Seungbum Hong studies the internal structure of piezoelectric materials. These are certain types of crystals that generate electricity when you squeeze them.
Batteries not needed?

The day is coming when heartbeats power pacemakers, sneakers charge cell phones during a jog, and tires power their own pressure sensors as they rotate.

Argonne biologist Rosemarie Wilton works on ways to stabilize antibodies, which tend to degrade over time.
Antibody builders

Because antibodies are naturally so good at recognizing a host of different pathogens, Argonne biologist Rosemarie Wilton has spent much of her career working to better stabilize antibodies and prevent them from degrading over time.

A high-resolution transmission electron microscopy image of the core of a single silver nanowire. The scale bar represents 5 nm in length.  The image was taken on the Argonne Chromatic Aberration-corrected TEM (ACAT) machine.
Sterling science: Strain in silver nanoparticles creates unusual “twinning”

When twins are forced to share, it can put a significant strain on their relationship. While this observation is perhaps unsurprising in the behavior of children, it is less obvious when it comes to nanoparticles.
