A low-cost method for solar-thermal conversion that's simpler and greener
Researchers at Columbia Engineering have developed a simple, low-cost, and environmentally sound method for fabricating a highly-efficient selective solar absorber (SSA) to convert sunlight into heat for energy-related applications. The team used a 'dip and dry' approach whereby strips coated with a reactive metal are dipped into a solution containing ions of a less reactive metal to create plasmonic-nanoparticle-coated foils that perform as well or better than existing SSAs, regardless of the sun's angle.

Solar hydrogen production by artificial leafs: Scientists analysed how a special treatment improves cheap metal oxide photoelectrodes
Metal oxides are promising candidates for cheap and stable photoelectrodes for solar water splitting, producing hydrogen with sunlight. Unfortunately, metal oxides are not highly efficient in this job. A known remedy is a treatment with heat and hydrogen. An international collaboration has now discovered why this treatment works so well, paving the way to more efficient and cheap devices for solar hydrogen production.

CWRU awarded funding to understand how plant particle stimulates anti-tumor response
Nicole Steinmetz, PhD, has received a major grant from the National Institutes of Health to help understand how a virus-like particle from plants stimulates potent anti-tumor responses. "This research is aimed at giving the body's own cancer-fighting capacity a major 'lift and push,'" said Steinmetz. "It also offers potential to fight cancer in dogs, who are of course members of our families as well. We are very grateful to the National Institutes of Health for supporting this potentially transformative work."

Recipe for safer batteries -- Just add diamonds
While lithium-ion batteries, widely used in mobile devices from cell phones to laptops, have one of the longest lifespans of commercial batteries today, they also have been behind a number of recent meltdowns and fires due to short-circuiting in mobile devices. In hopes of preventing more of these hazardous malfunctions researchers at Drexel University have developed a recipe that can turn electrolyte solution -- a key component of most batteries -- into a safeguard against the chemical process that leads to battery-related disasters.

Carbon nanotubes worth their salt
Lawrence Livermore scientists, in collaboration with researchers at Northeastern University, have developed carbon nanotube pores that can exclude salt from seawater. The team also found that water permeability in carbon nanotubes (CNTs) with diameters smaller than a nanometer (0.8 nm) exceeds that of wider carbon nanotubes by an order of magnitude.

Researchers report breakthrough in magnesium batteries
Magnesium batteries are safe -- unlike traditional lithium ion batteries, they are not flammable or subject to exploding -- but until now their ability to store energy has been limited. Researchers from the University of Houston reported a new design for the battery cathode, drastically increasing the storage capacity and upending conventional wisdom that the magnesium-chloride bond must be broken before inserting magnesium into the host.

Physicists find strange state of matter in superconducting crystal
New research published this week shows a rare state of matter in which electrons in a superconducting crystal organize collectively. The findings lay the groundwork for answering one of the most compelling questions in physics: How do correlated electron systems work, and are they related to one another?

No batteries required: Energy-harvesting yarns generate electricity
An international research team led by scientists at The University of Texas at Dallas and Hanyang University in South Korea has developed high-tech yarns that generate electricity when they are stretched or twisted. In a study published in the Aug. 25 issue of the journal Science, researchers describe 'twistron' yarns and their possible applications, such as harvesting energy from the motion of ocean waves or from temperature fluctuations.

Putting it to the test
University of Utah researchers led by chemical engineering and chemistry professor Marc Porter and U surgeon and professor Courtney Scaife have developed a rapid portable screening test for liver cancer that doesn't involve sending a specimen to a blood lab and cuts the wait time for results from two weeks to two minutes. This inexpensive test can be administered wherever the patient is, which will be valuable for developing nations with little access to hospitals.

Lego proteins revealed
According to Dr. Emmanuel Levy and his group in the Weizmann Institute of Science's Structural Biology Department, Lego-like assemblies should have formed relatively frequently during evolution. Could this assembly method be common, or even easy to reproduce? Their answer, which was recently published in Nature, may have implications for both biological research and nanoscience.

'Shapeshifter' that regulates blood clotting is visually captured for the first time
It has not been possible to witness exactly how von Willebrand factor senses and harnesses mechanical forces in our blood vessels -- until now. A team in the Boston Children's Program in Cellular and Molecular Medicine and the HMS Department of Biological Chemistry and Molecular Pharmacology has revealed exactly how VWF stops bleeding from cuts and bruises. Cutting-edge fluorescence imaging and microfluidic tools allowed them to capture images of individual VWF molecules elongating and relaxing in response to blood flow.

A more complete picture of the nano world
Aerosol particles, says Xiaoji Xu, assistant professor of chemistry at Lehigh University, are among the many materials whose chemical and mechanical properties cannot be fully measured until scientists develop a better method of studying materials at the microscale as well as the much smaller nanoscale (1 nm is one-billionth of a meter). Xu has developed such a method and utilized it to perform noninvasive chemical imaging of a variety of materials, as well as mechanical mapping with a spatial resolution of 10 nanometers.

Nanoparticle ink produces glowing holograms with simple inkjet printer
Researchers at ITMO University unveiled a new approach for printing luminescent structures based on nanoparticle ink. The unique optical properties of the ink were achieved by means of europium-doped zirconia. Particles of this material were proven to be useful for manufacturing glowing holographic coatings with a high degree of protection. Importantly, the developed approach enables the fabrication of custom holograms by means of a simple inkjet printer.
