Rollable graphene possible via new technique

The graphite found in pencils is made of layers of carbon stacked on top of each other, atom-thin sheets known as graphene. Graphene possesses a variety of unique electrical, mechanical, thermal and optical properties, leading scientists worldwide to research whether … Continue reading

Fatigue-resistant amorphous metals rely on zigzag cracks

Amorphous metals whose atomic arrangements resemble those of a liquid more than a crystal are often exceptionally strong when compared to their crystalline counterparts, but they are typically much less resistant to fatigue, greatly hampering their use. Now scientists find … Continue reading

Controlling macrophage behavior via cell shape

Macrophages are immune cells that gobble intruders, renegades and debris. Now researchers discover cell shape can help control macrophages — for instance, elongating them promotes behavior that enhances healing. These findings, detailed in the Proceedings of the National Academy of … Continue reading

Disk-shaped nanoparticles more easily absorbed than rods

Nanoparticles — particles only nanometers or billionths of a meter wide — are widely investigated as vehicles to help deliver drugs into patients. Now scientists find the shape of these nanoparticles influences how well they enter cells, with disk-shaped nanoparticles … Continue reading

A new use for rice — lithium ion batteries

Discarded rice husks could become standard ingredients for lithium ion batteries. Researchers in Korea report that rice husks — the tough, protective layer covering a rice kernel — are ideal sources of silicon for high-capacity lithium battery anodes. Their findings … Continue reading

The physics of clogged arteries: A “micro” story

What do rubber tires from the earliest automobiles have in common with fatty atherosclerotic plaques inside blood vessels in the human body? The way they rupture, it turns out, is driven by the same physical processes. In the 1920s, rubber … Continue reading
