A combined computational and experimental study of self-assembled silver-based structures known as superlattices has revealed an unusual and unexpected behavior: arrays of gear-like molecular-scale machines that rotate in unison when pressure is applied to them. Computational and experimental studies show that the superlattice structures, which are self-assembled from smaller clusters of silver nanoparticles and organic protecting molecules, form in layers with the hydrogen bonds between...

Researchers Create First Soluble 2D Supramolecular Organic Frameworks
2013-12-16 14:20:48

Lawrence Berkeley National Laboratory Supramolecular chemistry, aka chemistry beyond the molecule, in which molecules and molecular complexes are held together by non-covalent bonds, is just beginning to come into its own with the emergence of nanotechnology. Metal-organic frameworks (MOFs) are commanding much of the attention because of their appetite for greenhouse gases, but a new player has joined the field – supramolecular organic frameworks (SOFs). Researchers with the U.S....

Advanced Ink-jet Technology Prints Nanostructures With Self-assembling Material
2013-09-17 08:45:54

The University of Chicago A multi-institutional team of engineers has developed a new approach to the fabrication of nanostructures for the semiconductor and magnetic storage industries. This approach combines top-down advanced ink-jet printing technology with a bottom-up approach that involves self-assembling block copolymers, a type of material that can spontaneously form ultrafine structures. The team, consisting of nine researchers from the University of Illinois at...

[ Watch the Video: Magnetic Droplets on a Superhydrophobic Surface ] Enid Burns for redOrbit.com - Your Universe Online Scientists are experimenting with non-dissapative droplet patterns to study reversible switching between static and dynamic self-assembly. Researchers from Aalto University and Paris Tech studied water droplets containing nanoparticles on a strong water repellent surface to observe the self-assembly process. A video demonstrating the mesmerizing phenomena was posted...

Ecole Polytechnique Fédérale de Lausanne A colloid is a substance spread out evenly inside another substance. Everyday examples include milk, styrofoam, hair sprays, paints, shaving foam, gels and even dust, mud and fog. One of the most interesting properties of colloids is their ability to self-assemble — to aggregate spontaneously into well-defined structures, driven by nothing but local interactions between the colloid's particles. Self-assembly has been...

"In our current paper we present new computational results that explore how membranes may influence crucial biological processes", explains Richard Matthews, Lise-Meitner-Fellow at the University of Vienna and first author of the study. The focus of the investigation is the self-assembly of microscopic particles, the formation of structures or patterns without human intervention. More specifically, the effect of the interactions between membranes and proteins, which can influence the...

New technique allows production of complex microchip structures in 1 self-assembling step Researchers at MIT have developed a new approach to creating the complex array of wires and connections on microchips, using a system of self-assembling polymers. The work could eventually lead to a way of making more densely packed components on memory chips and other devices. The new method – developed by MIT visiting doctoral student Amir Tavakkoli of the National University of Singapore,...

Self-assembling nano boxes open the door to "smart" particles for medicine, manufacturing While it is relatively straightforward to build a box on the macroscale, it is much more challenging at smaller micro- and nanometer length scales. At those sizes, three-dimensional (3-D) structures are too small to be assembled by any machine and they must be guided to assemble on their own. And now, interdisciplinary research by engineers at Johns Hopkins University in Baltimore, Md., and...

In recent years, scientists have begun to harness DNA's powerful molecular machinery to build artificial structures at the nanoscale using the natural ability of pairs of DNA molecules to assemble into complex structures. Such "DNA origami," first developed at the California Institute of Technology, could provide a means of assembling complex nanostructures such as semiconductor devices, sensors and drug delivery systems, from the bottom up. While most researchers in the field are working...

Researchers at Brown and Johns Hopkins universities have found optimal configurations for creating 3-D geometric shapes – like tiny, highly simplified geodesic domes that assemble by themselves. The Brown team developed the algorithmic tools, and the Johns Hopkins team tested selected configurations. The research may lead to advances from drug-delivery containers to 3-D sensors and electronic circuits. Results published in Proceedings of the National Academy of Sciences. Material...
