No Assembly Required - Microparticles That Self-assemble
2012-10-31 15:46:47

Harvard University Scientists have created new kinds of particles, 1/100th the diameter of a human hair, that spontaneously assemble themselves into structures resembling molecules made from atoms. These new particles come together, or "self-assemble," to form structures in patterns that were previously impossible to make and hold promise for manufacturing advanced optical materials and ceramics. The method, described in the latest issue of the journal Nature, was developed by a team of...

To understand long-range interactions between particles at the micrometric scale, researchers utilize methods which are used to study the formation of our universe. Scientists have found that micron-size particles which are trapped at fluid interfaces exhibit a collective dynamic that is subject to seemingly unrelated governing laws. These laws show a smooth transitioning from long-ranged cosmological-style gravitational attraction down to short-range attractive and repulsive forces. The...

Microscopic spheres form strings in surprising alignments when suspended in a viscous fluid and sheared between two plates – a finding that will affect the way scientists think about the properties of such wide-ranging substances as shampoo and futuristic computer chips. A team of scientists at Cornell University and the University of Chicago have imaged this behavior and have explained the forces causing it for the first time. Its findings appear in the Dec. 19-23 early edition of...

Physical equilibrium, assumed to be almost instant, may take months or years for particles in oil-water mixtures By studying the behavior of tiny particles at an interface between oil and water, researchers at Harvard have discovered that stabilized emulsions may take longer to reach equilibrium than previously thought. Much longer, in fact. "We were looking at what we thought would be a very simple phenomenon, and we found something very strange," says principal investigator...

Nanoparticles of a substance can be counted and the size distribution can be determined by dispersing the nanoparticles into a gas. But some nanoparticles tend to aggregate when the surrounding conditions change. Scientists at the University of Gothenburg, Sweden, have shown that it is possible to sort and count the particles, even when they have formed aggregates. "Nanoparticles are already used in many everyday products, such as sunscreen and cosmetics. It is important to be able to...
