Spin fluctuations simpler than currents, researchers argue

A theoretical study shows that spintronic equations are vastly simplified by looking at spin density fluctuations rather spin currents.

DARPA announces Microsystems Exploration program

Program aims to accelerate revolutionary advances in microsystems technologies through targeted research investments.

New laws of attraction: Scientists print magnetic liquid droplets

Revolutionary material could lead to 3D-printable magnetic liquid devices for the fabrication of flexible electronics, or artificial cells that deliver targeted drug therapies to diseased cells.

Confined nanoscale sound controls light in a microresonator

Researchers demonstrate a semiconductor device for the tailored generation of Brillouin signals in the ultrahigh 100GHz-THz regime.

Ultra-soft, liquid magnetic droplets could vault technology forward

Researchers say magnetic field control of floating drops, like Harry Potter's wand, not magic anymore.

Adding a polymer stabilizes collapsing metal-organic frameworks

Porous metal-organic frameworks (MOFs) have many applications like carbon capture and water-cleaning. However, MOFs with large pores tend to collapse. Chemists and chemical engineers have now solved the problem by adding small amounts of a polymer into the MOF pores, an act that impedes pore collapse.

Researchers have demonstrated a single-molecule heat conductor

New study measures thermal conductance through a single molecule.
