Colored diamonds are a superconductor's best friend

“These diamond sensors combine high sensitivity with the potential for high spatial resolution, and since they operate at higher temperatures than their competitors – superconducting quantum interference device, or SQUID, magnetometers – they turn out to be good for studying high temperature superconductors,”

Pulling polymers with an AFM tip

Using the tip of the AFM, the researchers were able to pull single chains of molecules (polymers) off a gold surface. Remarkable behavior of nearly frictionless motion was predicted by a theoretical model and has now been verified for molecules on a gold surface.

Optical nano-tweezers take over the control of nano-objects

Researchers at ICFO have implemented plasmonic nano-tweezers at the extremity of a mobile optical fiber, nano-engineered with a bowtie-like gold aperture. Note that nanoHUB has a simulator for nano-scale bowtie antennae. See second link.

Large thermoelectric power from a combination of magnets and superconductors

According to the newly published research, a very large thermoelectric effect can be created in a structure combining a ferromagnet (F) to a thin superconductor film (S) via an insulator (I), and where the superconductor is in the presence of a spin-splitting field due to the presence of a ferromagnetic insulator (FI) or a magnetic field (B).
