Researchers from TU Delft and VU University Amsterdam in the Netherlands have demonstrated that the size of a metal alloy nanoparticle influences the speed with which hydrogen gas is released when stored in a metal hydride. The smaller the size of the nanoparticle, the greater the speed at which the hydrogen gas makes its way to the fuel cell.

Governor Andrew M. Cuomo today announced that New York State has entered into agreements providing for investments valued at a total of $4.4 billion over the next five years from five leading international companies to create the next generation of computer chip technology.
Graphene might overtake carbon nanotubes in commercial applications
Carbon nanotubes (CNTs) have not yet met commercial expectations from a decade ago, and now hot on its heels is graphene. Graphene is considered a hot candidate for applications such as computers, displays, photovoltaics, and flexible electronics. The biggest opportunity for both materials is in printed and potentially printed electronics. In a comparably short time a large amount of graphene materials have become commercially available contributing to further advancements and application development. At a fraction of the weight and cost of CNTs, graphene may displace carbon nanotubes and even indium tin oxide in some applications. Flexible, see-through displays may be the one application that finally puts graphene into the commercial spotlight.
Spontaneous combustion in nanobubbles
Nanometer-sized bubbles containing the gases hydrogen and oxygen can apparently combust spontaneously, although nothing happens in larger bubbles. For the first time, researchers have demonstrated this spontaneous combustion.

Researchers develop technique to control light from nanoparticles (w/video)
Twisted crystals point way toward active optical materials.
Abrupt escape from flatness
At first glance, it seems as if billions of lead atoms have mysteriously disappeared. When exposed to heat, a layer of lead coated onto a nickel surface becomes almost invisible from one moment to the next. In reality, the slightest disturbance causes these atoms to suddenly switch from a broad "flat pancake" shape to a compact hemisphere.
New etch process uses argon pulsing to improve silicon etch rate and selectivity
Engineers in the CNST NanoFab have developed a new plasma etching technique for silicon which improves the etch rate, the mask selectivity, and the sidewall profile by optimizing the addition of argon to the process flow.
