NIST Membrane Model May Unlock Secrets of Early-Stage Alzheimer's

Diagram of NIST's "tethered bilayer membrane" model shows the silica surface covered with gold at the bottom. Sulfur atoms (yellow spheres) bind to the gold and act as anchors for the tethers, chains of atoms extending up to the lipid bilayer membrane at the top of the structure. Image: NIST

High-temperature superconductor 'pseudogap' imaged

Sep 22, 2008
With the right combination of temperature (right scale) and percentage of doping (bottom scale), a cuprate crystal becomes superconducting (dark blue curve). As the percentage of doping decreases, a scanning tunneling microscope ...

World's thinnest balloon

Sep 19, 2008
Scientists have developed the world's thinnest balloon that is impermeable to even the smallest gas molecules. Above is a multi-layer graphene membrane that could be used in various applications, including filters and sensors. ...
