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 have discovered that stabilized emulsions may take longer to reach equilibrium than previously thought.

Researchers have successfully demonstrated a new method for producing a wide variety of complex hollow nanoparticles. The work applies well known processes of corrosion in a novel manner to produce highly complex cage-like nanoscale structures with potential applications in fields from medicine to industrial processing.

Computers can mimic the human ability to find visually similar images, such as photographs of a fountain in summer and in winter, or a photograph and a painting of the same cathedral, by using a technique that analyzes the uniqueness of images, say researchers. The research team found that their surprisingly simple technique performed well on a number of visual tasks that normally stump computers, including matching sketches of automobiles with photographs of cars.

New research describes how by using magnetic resonance imaging and nanoparticle technology, scientists can monitor the growth of laboratory-engineered blood vessels after implantation in patients. This is an important step toward ensuring that blood vessels, and tissues engineered from a patient's own biological material, are taking hold and working as expected. This is the first method for monitoring the growth and progress of engineered tissues once they are implanted.
