A new method to study lithium dendrites could lead to better, safer batteries

Lithium ion batteries often grow needle-like structures between electrodes that can short out the batteries and sometimes cause fires. Now, an international team of researchers has found a way to grow and observe these structures ...

Hummingbirds' rainbow colors come from pancake-shaped structures in their feathers

Hummingbirds are some of the most brightly-colored things in the entire world. Their feathers are iridescent— light bounces off them like a soap bubble, resulting in shimmering hues that shift as you look at them from different ...

Walking with atoms—chemical bond making and breaking recorded in action

Ever since it was proposed that atoms are building blocks of the world, scientists have been trying to understand how and why they bond to each other. Be it a molecule (which is a group of atoms joined together in a particular ...

Nearly quantized conductance plateau of vortex mode in an iron-based superconductor

When a semiconducting nanowire is coupled to a superconductor, it can be tuned to topological quantum states thought to host localized quasiparticles known as Majorana Zero Modes (MZM). MZMs are their own antiparticles, with ...

Turning up the heat to create new nanostructured metals

Scientists have developed a new approach for making metal-metal composites and porous metals with a 3-D interconnected "bicontinuous" structure in thin films at size scales ranging from tens of nanometers to microns. Metallic ...

Mysteries behind interstellar buckyballs finally answered

Scientists have long been puzzled by the existence of so-called "buckyballs"—complex carbon molecules with a soccer-ball-like structure—throughout interstellar space. Now, a team of researchers from the University of ...

World-leading microscopes take candid snapshots of atoms in their 'neighborhoods'

We can directly see the hidden world of atoms thanks to electron microscopes, first developed in the 1930s. Today, electron microscopes, which use beams of electrons to illuminate and magnify a sample, have become even more ...

Team uses golden 'lollipop' to observe elusive interference effect at the nanoscale

Electrons in atoms are pretty talented. They can form chemical bonds, get kicked out of the atom and even "jump" to different locations based on their energetic states.

Magnetic tuning at the nanoscale

In collaboration with colleagues from the Leibniz Institute for Solid State and Materials Research Dresden (IFW) and the University of Glasgow, physicists from the German research center Helmholtz-Zentrum Dresden-Rossendorf ...

A tech jewel: Converting graphene into diamond film

Can two layers of the "king of the wonder materials," i.e. graphene, be linked and converted to the thinnest diamond-like material, the "king of the crystals?" Researchers of the Center for Multidimensional Carbon Materials ...
