Nature Inspires More Efficient Water Splitting

July 1, 2014 12:00 pm | by RIKEN | News | Comments

Nature's water-splitting catalysts, based on manganese, are incredibly efficient, and scientists have long been studying why this is and how we can mimic the natural system. Now, researchers have discovered a mineral-based catalyst that can efficiently split water into oxygen and hydrogen ions at neutral pH.

Pressure May Be Better than Chemistry for Making Nanostructures

June 30, 2014 7:00 am | by Sandia National Laboratories | News | Comments

You wouldn’t think that mechanical force— the simple kind used to eject unruly patrons from bars, shoe a horse or emboss the raised numerals on credit cards— could process nanoparticles more subtly than the most advanced chemistry. Yet, researchers appear to have achieved a start toward that end.

Researchers have developed a method for measuring cortisol in saliva using a smartphone and a disposable test strip. This innovation enables anyone with a smartphone to measure their salivary cortisol level quickly, accurately and affordably.

Palladium-gold Catalyst Converts Waste to Chemicals

June 27, 2014 12:00 pm | by Rice Univ. | News | Comments

Researchers have discovered a palladium-gold nanocatalyst that is faster— about 10 times faster— at converting glycerol into high-value products than catalysts of either metal alone.

Chemists Develop Magnetically Responsive Liquid Crystals

June 27, 2014 7:00 am | by UC Riverside | News | Comments

Chemists have constructed liquid crystals with optical properties that can be instantly and reversibly controlled by an external magnetic field. The research paves the way for display applications relying on the instantaneous and contactless nature of magnetic manipulation— such as signage, posters, writing tablets and billboards.


Newly Found Chemical Aids Drug Manufacturing

June 27, 2014 7:00 am | by Queen Mary Univ. of London | News | Comments

Samples from 1950s Finally Analyzed

June 27, 2014 7:00 am | by Georgia Institute of Technology | News | Comments

Stanley Miller, the chemist whose landmark experiment showed how some of the molecules of life could have formed on a young Earth, left behind boxes of experimental samples that he never analyzed. The first-ever analysis of some of Miller’s old samples has revealed another way that important molecules could have formed on early Earth.

Particle-sorting Method Breaks Speed Records

June 27, 2014 7:00 am | by MIT, David Chandler | News | Comments

A new way of processing biological fluid samples could make such detections possible in real time. The technique could allow cells to be sorted while hurtling through the channels of a microfluidic device at speeds faster than those of race cars— at least 100 times faster than any existing system.

Research Yields Result for Organic Reactions in Water

June 27, 2014 7:00 am | by McGill Univ. | News | Comments

Green-chemistry researchers have discovered a way to use water as a solvent in one of the reactions most widely used to synthesize chemical products and pharmaceuticals.

Scientists Create Mythical God's Capsules

June 27, 2014 7:00 am | by Institute of Physical Chemistry of the Polish Academy of Sciences | News | Comments

Theoreticians have long been able to design models of Janus capsules— miniature, hollow structures, in different fragments composed of different micro- and nanoparticles. But the challenge was to produce them. Now, researchers have found that Janus capsules can be produced easily and at low cost.


Battery is Cheap, Rechargeable, Organic

June 26, 2014 12:00 pm | by Univ. of Southern California | News | Comments

Scientists have developed a water-based organic battery that is long lasting and built from cheap, eco-friendly components. The new battery, which uses no metals or toxic materials, is intended for use in power plants, where it can make the energy grid more resilient and efficient.

Neanderthals Ate Their Veggies

June 26, 2014 12:00 pm | by MIT, Jennifer Chu | News | Comments

The popular conception of the Neanderthal as a club-wielding carnivore is, well, rather primitive, according to a new study. Instead, our prehistoric cousin may have had a more varied diet that, while heavy on meat, also included plant tissues, such as tubers and nuts.

Tofu Ingredient Could Aid Solar Panels

June 26, 2014 12:00 pm | by Univ. of Liverpool | News | Comments

A chemical used to make tofu and bath salts could also replace a highly toxic and expensive substance used to make solar cells. Safe and at a fraction of the cost– $0.001 per gram compared to $0.3– it has also been shown to be as effective as the expensive and toxic alternative.

Food Oder is Based on Only a Few Volatile Compounds

June 26, 2014 7:00 am | by Angewandte Chemie | News | Comments
