Rational design of protein architectures not found in nature

Computational design of proteins satisfying predetermined geometric constraints produced stable proteins with the designed structure that are not found in nature.

De novo protein design space extends far beyond biology

A fully automated design protocol generates dozens of designs for proteins based on helix-loop-helix-loop repeat units that are very stable, have crystal structures that match the design, have very different overall shapes, and are unrelated to any natural protein.

Conference video: Nanoscale Materials, Devices, and Processing Predicted from First Principles

Prof. William Goddard presented four advances from his research group that enable going from first principles quantum mechanics calculations to realistic nanosystems of interest with millions or billions of atoms.

Conference video: Mythbusting Knowledge Transfer Mechanisms through Science Gateways

Prof. Gerhard Klimeck described the success of nanoHUB.org, a science and engineering gateway providing online simulations through a web browser for nanotechnology research and education.

DNA nanotechnology controls which molecules enter cells

DNA building blocks mimic biological ion channels to more precisely control which molecules can cross a biological membrane.

Molecular arm grabs, transports, releases molecular cargo

A molecular robotic arm synthesized from small synthetic organic molecules uses cyclic changes in pH and other reaction conditions to grab and release a cargo molecule, and swing the cargo back and forth between the two ends of the molecular platform.

Electron tomography reveals precise positions of individual atoms in aperiodic material

The positions of 3769 tungsten atoms in a tungsten needle segment were determined to a precision of 19 pm (0.019 nm), including the position of a single atom defect in the interior of the sample, by using aberration-corrected scanning transmission electron microscopy and computerized tomography.

Nanoparticles ameliorate MS in mice by inducing immune tolerance of myelin

In the first mouse model of the progressive form of multiple sclerosis, nanoparticles that created immune tolerance to myelin prevented the development of progressive MS.

Inexpensive transparent conductors from correlated metal nanostructures

Highly correlated electron motions resembling electron liquids rather than electron gases, and found in some transition metal oxides, may enable inexpensive substitution for expensive displays.

Active and reversible control of nanoparticle optical properties

Electrochemically modifying individual metallic nanoparticles and pairs of such nanoparticles enabled reversible tuning of their optical properties, including charge transfer plasmon formation in nanoparticle pairs.
