Meeting the 'grand challenge' of a sustainable water supply


Scientists and engineers must join together in a major new effort to educate the public and decision makers on a crisis in providing Earth's people with clean water that looms ahead in the 21st century. That's the focus of a comment article in the current edition of Chemical & Engineering ...


Driving magnesium micromotors with seawater


Scientists in the California have developed magnesium-based Janus micromotors that self-propel in seawater. Research shows how the micromotors can be used to capture and transport oil droplets from contaminated seawater, presenting a possible environmental application for the removal of oil ...


Stanford ultraresponsive magnetic nanoscavengers for next generation water purification

New synthetic cored nanoparticle could decontaminate tainted water and then be cleared with a magnet


Among its many talents, silver is an antibiotic. Titanium dioxide is known to glom on to certain heavy metals and pollutants. Yet other materials do the same for salt. In recent years, environmental engineers have sought to disinfect, depollute, and desalinate contaminated water using nanoscale ...


Keeping beverages cool in summer

It's not just the heat, it's the humidity


In spring a person's thoughts turn to important matters, like how best to keep your drink cold on a hot day. Though this quest is probably as old as civilization, University of Washington climate scientists have provided new insight. It turns out that in sultry weather condensation on the outside ...


Researchers trap light, improve laser potential of MEH-PPV polymer


Researchers from North Carolina State University have come up with a low-cost way to enhance a polymer called MEH-PPV's ability to confine light, advancing efforts to use the material to convert electricity into laser light for use in photonic devices. "Think of a garden hose. If it has holes in ...


Scotch tape finds new use as grasping 'smart material'


Scotch tape, a versatile household staple and a mainstay of holiday gift-wrapping, may have a new scientific application as a shape-changing "smart material." Researchers used a laser to form slender half-centimeter-long fingers out of the tape. When exposed to water, the four wispy fingers morph ...


Pyroelectric nanogenerator charges Li-ion battery with harvested energy


The idea of harvesting ambient energy from the environment that would otherwise not be purposefully used is, in theory, a great way to produce green, renewable energy. But the biggest problem in this fairly new area of research is that scientists have yet to find a method that can harvest very ...


In chemical reactions, water adds speed without heat


An international team of researchers has discovered how adding trace amounts of water can tremendously speed up chemical reactions—such as hydrogenation and hydrogenolysis—in which hydrogen is one of the reactants, or starting materials. Led by Manos Mavrikakis, the Paul A. Elfers professor of ...

How seawater could corrode nuclear fuel


Japan used seawater to cool nuclear fuel at the stricken Fukushima-Daiichi nuclear plant after the tsunami in March 2011 -- and that was probably the best action to take at the time, says Professor Alexandra Navrotsky of the University of California, Davis. But Navrotsky and others have since ...


Cost-effective Determination of Inorganic Anions and Cations in Municipal Drinking Water


Thermo Fisher Scientific Inc. announced a new application demonstrating the separation of common inorganic anions and cations in municipal drinking water samples on the capillary Thermo Scientific Dionex IonPac AS19 hydroxide-selective anion-exchange column and the Thermo Scientific Dionex IonPac ...
