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.

Rolling DNA-based motors increase nano-walker speeds 1000-fold

Coating micrometer-sized glass spheres with hundreds of DNA strands complementary to an RNA covering a glass slide enables the sphere to move, with the help of an enzyme that digests RNA bound to complementary DNA, a thousand times faster than conventional DNA-walkers.

Octopodal nanoparticles combine catalytic, plasmonic functions

Eight-armed nanoparticles of gold coated with a gold-palladium alloy proved to be both efficient plasmonic sensors and efficient catalysts, even though gold alone is not normally a good catalyst and palladium is a poor plasmonic material.

Novel nanoconjugate delivers synergistic combination of microRNAs to treat cancer

Two microRNAs with synergistic effects, one that suppresses tumor growth and another than inhibits tumor promotion, are combined in an RNA triple helix, complexed with a dendrimer to form nanoparticles, which are incorporated with a polymer to form a hydrogel that inhibits tumor growth when applied to the tumor.
