When petroleum companies abandon an oil well, more than half the reservoir's oil is usually left behind as too difficult to recover. Now, however, much of the residual oil can be recovered with the help of nanoparticles and a simple law of physics.

The next breakthrough in highly efficient battery technologies and solar cells may very well be nanoscopic crystals of silicon assembled like skyscrapers on wafer-??scale substrates. An important route for growth of these nanoscale 'whiskers' - or nanowires - involves alloyed metal droplets. Moneesh Upmanyu has been using computational tools to understand the atomic-??scale interactions between these droplets and the growth of nanowires.

Researchers have demonstrated in experiment that by abandoning the phase preservation requirement it is possible to create invisibility cloaking for natural light in multiple observation angles. Such a cloak will act as a cloaking device operational on the ray optics approximation. It will disregard the fine effects of interference seen in wave optics but will offer good performance for hiding macroscopic objects much larger than the wavelength of light.

Read moreAccording to new research from the Monell Center and collaborating institutions, odors from human skin cells can be used to identify melanoma, the deadliest form of skin cancer. In addition to detecting a unique odor signature associated with melanoma cells, the researchers also demonstrated that a nanotechnology-based sensor could reliably differentiate melanoma cells from normal skin cells.

Cheaper clean-energy technologies could be made possible thanks to a new discovery. Researchers have found that an important chemical reaction that generates hydrogen from water is effectively triggered - or catalyzed - by a nanoparticle composed of nickel and phosphorus, two inexpensive elements that are abundant on Earth.

The German physicist is to be honoured for his groundbreaking work in the field of quantum simulation with ultracold atoms. In his experiments, Bloch creates microscopic 'light crystals' from laser beams in whose optical lattices ultracold atoms are trapped. This quantum simulator serves as a model for the examination of fundamental quantum mechanics processes in materials such as metals.

Researchers from North Carolina State University have developed a method for creating "nano-volcanoes" by shining various colors of light through a nanoscale "crystal ball" made of a synthetic polymer. These nano-volcanoes can store precise amounts of other materials and hold promise for new drug-delivery technologies.
