Kitchen sponge supercapacitor has many porous benefits

By dipping small pieces of an ordinary kitchen sponge into solutions of nanoscale electrode materials, scientists have created a light-weight, low-cost supercapacitor that benefits from the sponge's porous structure. The pores provide a large surface area for the electrode materials to attach to, leading to an increase in ion movement between the electrodes and the electrolyte that fills in the pores. Overall, the new supercapacitor exhibits a performance that is superior to that of one made of the same electrode materials but without the sponge.

Swapping tellurium for sulfur improves light absorption in organic solar cells

The investigation of light absorbing organic semiconductors is important for the development of lightweight flexible solar cells. Replacing sulfur atoms in commonly used, polymer-based solar cells with tellurium atoms results in materials that absorb a wider range of wavelengths of sunlight. A tellurophene-containing low-bandgap polymer (PDPPTe2T) was synthesized by microwave-assisted palladium-catalyzed ipso-arylative polymerization of 2,5-bis[(α-hydroxy-α,α-diphenyl)methyl]tellurophene with a diketopyrrolopyrrole (DPP) monomer.

Precision growth of light-emitting nanowires

A novel approach to growing nanowires promises a new means of control over their light-emitting and electronic properties. In a recent issue of Nano Letters, scientists from the U.S. Department of Energy's Lawrence Berkeley National Lab (Berkeley Lab) demonstrated a new growth technique that uses specially engineered catalysts. These catalysts, which are precursors to growing the nanowires, have given scientists more options than ever in turning the color of light-emitting nanowires.

Why 'baking powder' increases efficiency of plastic solar cells

The efficiency of plastic solar cells can be doubled or tripled if an extra solvent is added during the production process, comparable with the role of baking powder in dough mixture. Exactly how this works has been unclear for the last ten years. But now researchers at Eindhoven University of Technology (TU/e) have come up with the answer in a publication in Nature Communications. This new understanding will now enable focused development of plastic solar cells.

Physics news

Researchers use transmission electron microscope as a thermometer at nanoscale

A team of researchers with the University of California has found a way to use a transmission electron microscope (TEM) as a thermometer for measuring heat in micro-electric devices. In their paper published in the journal Science, the team describes how they discovered using a TEM on a tiny piece of metal could reveal its density change as electrons passed through. Christian Colliex with the L'Université de Paris, offers a Perspective piece on the work by the team in the same journal edition.

Astronomy & Space news

FAA appears to be attempting to expand its authority to moon activities

The U.S. Federal Aviation Administration has caused a bit of stir by hinting that it plans to expand its authority to include exploration of the moon and the use of its resources. News agency Reuters has reported that it has obtained a copy of a letter composed by officials with the agency and sent to U.S. based Bigelow Airspace—in it, the agency said it plans to leverage its launching authority by adding licensing authority of moon assets—all to encourage private companies to invest in such activities. The reason such a move has caused a stir, of course, is because it appears that the U.S. agency is attempting to expand its oversight into an area where it does not have the authority to do so.

The ages of sun-like stars

The mass of a star is perhaps its most significant feature. It determines how brightly it shines (a star ten times more massive than the Sun will, during its normal lifetime, shine about forty million times brighter than a star ten times less massive than the Sun), how long it will live (tens of millions of years versus tens of billions of years, respectively, for these two cases), and how it will eventually die (as a supernova or as slowly cooling clump of ashes). The next most significant property of a star is its age, which fixes its current character, the age of its planetary system, and the evolutionary state of its environment, and moreover which can be used to refine details in the theory of how stars evolve.

Astronomers breathe new life into venerable instrument

How do astronomers determine the shapes of objects that are too far away to photograph? One method is by using spectropolarimetry, an observational technique that measures the way light waves align after they scatter through clouds of gas and dust in space. The Half-wave Spectropolarimeter (HPOL) is an instrument designed by Wisconsin astronomer Dr. Kenneth Nordsieck in 1989 to conduct these measurements. During HPOL's 15-year lifetime at the University of Wisconsin's Pine Bluff Observatory (PBO), astronomers worldwide used data from HPOL to study the gas and dust surrounding planets, comets, stars, and supernovae, as well as the interstellar medium within our Milky Way Galaxy.

Researchers find chromosomal risk factors for a spinal disorder common in Japan

The spinal cord runs through a canal in the vertebrae that is lined with soft protective tissues. In patients with a condition known as ossification of the posterior longitudinal ligament of the spine (OPLL), bone begins to form within one of these tissues. The resulting narrowing of the spinal canal compresses the spinal cord, inflicting motor weakness, numbness and pain.

The battle for iron: Understanding anemias of the chronically ill

When we think of how we fight disease, the image of cells in our immune system fending off microbial invaders often comes to mind. Another strategy our bodies can employ is to cut off the enemy's supply lines and effectively starve disease-causing microbes of the iron they need to function. However, this tactic can backfire and cause anaemia if the iron-starved state is sustained for too long, a common problem in chronically ill patients. The search for therapies against this anaemia of chronic disease (ACD) could take on new directions thanks to a study published today in Blood. In it, scientists in the Molecular Medicine Partnership Unit, a joint venture of the European Molecular Biology Laboratory (EMBL) and Heidelberg University Clinic, both in Heidelberg, Germany, have found a hitherto unknown way through which mice starve pathogens of iron.
