Stanford scientists develop a water splitter that runs on an ordinary AAA battery
(Stanford University) Although touted as zero-emissions vehicles, most fuel cell vehicle run on hydrogen made from natural gas. Now Stanford scientists have developed a low-cost, emissions-free device that uses an ordinary AAA battery to produce hydrogen by water electrolysis. Unlike other water splitters that use precious-metal catalysts, the electrodes in the Stanford device are made of inexpensive and abundant nickel and iron.

Shaping the future of nanocrystals
(DOE/Lawrence Berkeley National Laboratory) Berkeley Lab researchers have recorded the first direct observations of how facets form and develop on platinum nanocubes in solution, pointing the way towards more sophisticated and effective nanocrystal design and revealing that a nearly 150 year-old scientific law describing crystal growth breaks down at the nanoscale.

Water window imaging opportunity
(Springer) Ever heard of the water window? It consists of radiations in the 3.3 to 4.4 nanometer range, which are not absorbed by the water in biological tissues. A new theoretical study identifies the physical mechanism needed to efficiently generate harmonic radiations at high laser intensities that occur beyond the saturation threshold of atoms and molecules. These findings, aimed at improving conventional methods of coherent radiation production to reach the water window, were published in EPJ D.

Scientists observe quantum vortices in cold helium droplets
(Deutsches Elektronen-Synchrotron DESY) An international research team including DESY scientists has observed tiny quantum vortices in cold droplets of liquid helium. It is the first time that the quantum vortices, which have been observed in larger samples of superfluid helium before, have been detected in nanodroplets, as the team reports in the journal Science. 'The experiment has exceeded our best expectations,' says Andrey Vilesov of the University of Southern California, one of the experiment's three leads.

Water and sunlight the formula for sustainable fuel
(Australian National University) An Australian National University team has successfully replicated one of the crucial steps in photosynthesis, opening the way for biological systems powered by sunlight which could manufacture hydrogen as a fuel.

Seeing a molecule breathe
(Academy of Finland) For the first time, chemists have succeeded in measuring vibrational motion of a single molecule with a femtosecond time resolution. The study reveals how vibration of a single molecule differs from the behavior of larger molecular groups.

MIPT and RAS scientists made an important step towards creating medical nanorobots
(Moscow Institute of Physics and Technology) Researchers at Moscow Institute of Physics and Technology and Russian Academy of Sciences made an important step towards creating medical nanorobots discovering a way of enabling them to produce logical calculations using a variety of biochemical reactions.

Training the next generation of cancer nanomedicine scientists
(Northeastern University) Northeastern University has received a five-year, $1.15 million grant from the National Institutes of Health's National Cancer Institute to train the next generation of cancer nanomedicine scientists and clinicians through a unique experiential learning program.

Promising ferroelectric materials suffer from unexpected electric polarizations
(DOE/Brookhaven National Laboratory) Brookhaven Lab scientists find surprising locked charge polarizations that explain the poor performance of next-gen materials that would otherwise revolutionize data-driven devices.

Artificial cells act like the real thing
(Weizmann Institute of Science) Weizmann Institute scientists have created an artificial, network-like cell system that is capable of reproducing the dynamic behavior of protein synthesis. This achievement is not only likely to help gain a deeper understanding of basic biological processes, but it may, in the future, pave the way toward controlling the synthesis of both naturally-occurring and synthetic proteins for a host of uses.
