Whether a solid or liquid forms from charged polymers depends on the “handedness” of the oppositely charged polymer chains.12.14.15Science Highlight

Will It Be a Solid or a Liquid? The Molecular Structure Has the Answer

Oppositely charged polymer chains can be “right-handed,” “left-handed,” or have no “handedness” at all, which controls whether a solid or liquid forms. Read More »

A simple chemical analogue to a biological cell responds to a perceived threats.11.01.15Science Highlight

Spontaneous Pressure Regulation within Artificial Cells

Simple human-made cellular analogues both sense and regulate in response to externally created stress. Read More »

A stripe-shaped magnetic region (domain), shown in blue (top left) in an ultrathin film device (orange structure). The narrowing region of the device causes the current distribution to change (two of the three red arrows change direction), leading to the breakdown of the magnetic domain into circular disk-shaped bubbles, called skyrmions (bottom left) Magnetic skyrmion bubbles (bottom right) were experimentally observed using magnetic imaging.11.01.15Science Highlight

Creating Novel Magnetic Islands for Spintronics

Generating and moving small, stable magnetic islands at room temperature could be the ticket to more energy-efficient electronics. Read More »

Schematic drawing shows an electron (gold sphere) moving in the direction of the green arrow on the surface of a topological crystalline insulator. In this material, the electron’s quantum-mechanical spin (up) (blue arrow) is coupled with the direction of its motion in such a way that reversing its direction of motion would reverse the direction of the spin (down).11.01.15Science Highlight

You Can Have Your Conductor and Insulator, Too
