Stanford scientists develop low-cost water splitter

 “This is the first time anyone has used non-precious metal catalysts to split water at a voltage that low. …It’s quite remarkable, because normally you need expensive metals, like platinum or iridium, to achieve that voltage.” ‘Haotian eventually discovered that nickel-iron oxide is a world-record performing material that can catalyze both the hydrogen and the oxygen reaction,’ Cui said. ‘No other catalyst can do this with such great performance.’


LMU/MPQ-scientists can image the optical properties of individual nanoparticles with a novel microscope.

Nanomaterials play an essential role in many areas of daily life. There is thus a large interest to gain detailed knowledge about their optical and electronic properties. Conventional microscopes get beyond their limits when particle size falls to the range of a few ten nanometers where a single particle provides only a vanishingly small signal. As a consequence, many investigations are limited to large ensembles of particles. Now, a team of scientists of the Laser Spectroscopy Division of Prof. Theodor W. Hänsch (Director at the Max Planck Institute of Quantum Optics and Chair for Experimental Physics at the Ludwig-Maximilians-Universität Munich) has developed a technique, where an optical microcavity is used to enhance the signals by more than 1000-fold and at the same time achieves an optical resolution close to the fundamental diffraction limit. The possibility to study the optical properties of individual nanoparticles or macromolecules promises intriguing potential for many areas of biology, chemistry, and nanoscience.

“A pioneering new technique to produce high-quality, low cost graphene could pave the way for the development of the first truly flexible ‘electronic skin’, that could be used in robots… This new technique grows graphene 100 times faster than conventional methods, reduces costs by 99 % and has enhanced electronic quality.”

Breakthrough may lead to industrial production of graphene devices

“With properties that promise faster computers, better sensors and much more, graphene has been dubbed the ‘miracle material’. But progress in producing it on an industrial scale without compromising its properties has proved elusive. University of Groningen scientists may now have made a breakthrough. Their results will be published in the journal Nano Letters.”Read more at: http://phys.org/news/2015-02-breakthrough-industrial-production-graphene-devices.html#jCp

Scientists predict green energy revolution after incredible new graphene discoveries.

“Essentially you pump your fuel from the atmosphere and get electricity out of this fuel, in principle. Before this paper, this wouldn’t even be speculation; it would be science fiction.

“Crumpled ‘graphene paper’ has potential to store energy” (www.theengineer.co.uk)

“To make the crumpled graphene paper, a sheet of the material was placed in a mechanical device that first compressed it in one direction, creating a series of parallel folds or pleats, and then in the other direction, leading to a rumpled surface. When stretched, the material’s folds smooth themselves out.

Forming a capacitor requires two conductive layers – namely two sheets of crumpled graphene paper – with an insulating layer in between, which in this demonstration was made from a hydrogel material.

Like the crumpled graphene, the hydrogel is highly deformable and stretchable, so the three layers remain in contact even while being flexed and pulled.”

All eggs in the Graphene basket? (Graham Pitcher)

“Yet other materials are available. Take MoS2, for example. Three years ago, a Swiss research team suggested MoS2 could enable transistors that consume a mere fraction of the power consumed by a silicon transistor. Two years ago, a team from MIT concluded MoS2 could enable new electronic devices and suggested it was time for graphene to ‘move over’. Now, researchers from Southampton have joined in, claiming that MoS2 not only matches graphene’s properties, but can also emit light.”

“Kim Jeehwan says that his techniques could be the “next big thing” in high-frequency transistors, photodetectors, biosensors and other “post-silicon era” devices, for which IBM is investing $3 billion over the next five years. He described graphene as the world’s “first two-dimensional material.”
