A Spoonful of This New Material Can Suck Up a Whole Roomful of Oxygen

A team of scientists in Denmark just invented a crystalline material that can absorb oxygen with astounding efficiency. How astounding? Well, a single spoonful of the stuff can suck all of the oxygen out of a room. The best part is that it can release it again with just a little bit of heat. Say goodbye to bulky oxygen tanks.

NASA-Funded Rocket Has Six Minutes to Study Solar Heating

On Sept. 30, 2014, a sounding rocket will fly up into the sky — past Earth’s atmosphere that obscures certain wavelengths of light from the sun — for a 15-minute journey to study what heats up the sun’s atmosphere.

Novel technique produces ethanol from carbon monoxide | GizMag.com

Ethanol may be touted as a more eco-friendly alternative to fossil fuels, but it’s not without its own drawbacks. Most importantly, the corn or other plants required as feedstock often take up field space that could otherwise be put to use growing food crops. Also, as with other plants, the feedstock crops require large amounts of water and fertilizer. Now, however, scientists at Stanford University have devised a method of producing liquid ethanol from carbon monoxide gas.

 

The technology was developed by assistant professor of chemistry Matthew Kanan and graduate student Christina Li. Whereas plant-based ethanol is obtained through a fermentation process, their technique involves taking water saturated with carbon monoxide gas, and placing it in an electrochemical cell at room temperature.

 

Like other fuel cells, theirs has two electrodes (an anode and a cathode), which an electrical current flows between. In the case of a hydrogen fuel cell, the application of that current would convert ordinary water contained within the cell into oxygen gas and hydrogen gas. By using a cathode made of oxide-derived copper, however, Kanan and Li were able to reduce the carbon monoxide in their water into ethanol and acetate.

Could moly sulfide be the key to cheaper hydrogen production? | GizMag.com

Chemical engineers have found a 30-year-old recipe that stands to make future hydrogen production cheaper and greener. The recipe has led researchers to a way to liberate hydrogen from water via electrolysis using molybdenum sulfide – moly sulfide for short – as the catalyst in place of the expensive metal platinum.

 

While hydrogen is relatively abundant here on Earth, it is generally bound to either carbon or oxygen to form methane and water respectively. Producing hydrogen currently involves liberating it from methane at a cost of between US$1 and $2 per kilogram. And the world’s hunger for hydrogen continues to grow, currently we consume 55 billion kilograms of the element per year, making freeing it from methane or water big business. And with numerous automakers dipping their tires in the hydrogen fuel waters, it’s set to get much bigger.

 

The other side of the equation is the by-product of production. When hydrogen is freed from methane the waste product is carbon, which is released into the atmosphere furthering climate change. Producing hydrogen from water on the other hand produces oxygen as waste.

 

The limiting factor to getting hydrogen from water in the past has been the expense of electrolysis, the process were hydrogen atoms are liberated from their bond with oxygen in water by passing an electrical current through an electrode immersed in the water. The main expense in this process was the use of platinum as the electrode. The efficiency of platinum to catalyze the breaking of hydrogen-oxygen bonds in water to free the hydrogen until now has been unmatched.

 

Enter moly sulfide. Since World War II, moly sulfide has been used by petroleum engineers in the refinement of oil. It was thought to be inefficient for the electrolysis of hydrogen from water due to the molecular structure at its surface.
