In a conventional fossil-fuel plant that's prohibitively expensive, since the CO2 is mixed in with nitrogen.
But recently, it was shown that spiking TiO2 with nitrogen ions gives it photocatalytic capabilities in UV light and visible light.
The subsequent industrial production of billions of tonnes of synthetic nitrogen fertilisers - particular after the 1950s - have flooded terrestrial and aquatic ecosystems with reactive nitrogen, and supported the century's human population explosion.
The process involves freezing a corpse with liquid nitrogen, then vibrating it to reduce the body to powder.
For instance, random electrical fluctuations tend to overwhelm them unless they are kept chilled with liquid nitrogen although making the islands smaller, paradoxically, reduces this problem.
The company is also experimenting with a new way of storing the hydrogen that will fuel its cells a fabric made of fibres of activated carbon that can (when cooled with liquid nitrogen) soak up the same amount of energy per kilogram as petrol.
The scientific explanation - streams of charged particles from sun storms interacting with electrons in nitrogen and oxygen atoms in the earth's upper atmosphere - does little to demystify the experience.
To simulate the atmosphere, they have built a special cloud chamber of their own, with the air manufactured from scratch, using liquid nitrogen and oxygen together with precise amounts of trace compounds, including sulphuric acid and ammonia.
Water-ice covers Charon, while Pluto's surface is predominantly nitrogen frost with traces of methane and carbon monoxide ices.
By footling round with centrifuges and liquid nitrogen they were reducing food to a set of mental hurdles, as though there weren't already enough traffic lights and zebra crossings in life.
Three-quarters of the company's sales are of nitrogen fertilizers, and it has a big position in domestic production, with two of the three largest nitrogen fertilizer plants in North America.
Rather than rotating corn planting with soybeans to replace soil nitrogen, many farmers are planting corn year after year and adding large amounts of nitrogen fertilizer.
Instead, a low-energy nuclear reactor (LENR) uses common, stable elements like nickel, carbon, and hydrogen to produce stable products like copper or nitrogen, along with heat and electricity.

The plan was for OCO's measurements to be synchronised with an analysis of ozone, nitrogen dioxide, methane and other greenhouse gases by the rest of the fleet.
Also, to comply with prevailing U.S. emissions standards on nitrogen oxides, or NOx, these big diesels require fairly complicated systems of postcombustion treatment with a water-based urea solution, called AdBlue.

The residents, for instance, of Kafue, an industrial town that once bustled with workers at its textile and nitrogen factories, now talk of unemployment, the cost of sending children to school and stinking garbage.
With 40, 000 pounds of nitrogen spilling into Jamaica Bay everyday, underwater forests of algae are threatening to kill off existing life in the water in much the same way that they did in the turn of the century.
According to a recent study, Leicester has the highest levels of nitrogen dioxide in England, with Nottingham recording the second highest.
In 96 tiny wells robotic arms mixed variations of molecules containing nitrogen, oxygen and sulphur with metals such as zirconium, titanium and hafnium.
FORBES: Upstart Symyx is shaking up the stodgy chemicals industry.
They fill the container with pure air made by evaporating liquid nitrogen and liquid oxygen, and add water vapour and some trace gases.
The largest problem is the dangerous amount of nitrogen oxide (which mixes with vehicle-exhaust gas to create ozone, and then smog) coughed out by the state's industrial plants.
They hired a scientist to come up with a formulation of chemicals that delivered nitrogen, potassium and phosphorus in highly water-soluble form, so that an impatient gardener could give plants an instant shot to the leaves, so to speak.
Though he's known for upgrading traditional Southern cuisine with cutting-edge techniques (he uses liquid nitrogen in cold-milling corn for grits), Mr. Brock believes cooking simply is just as challenging as cooking with modern gadgets.

With engines switched off, approximately 1, 000 pounds of nitrogen oxides emissions, 165 pounds of sulfur oxides, and 30 pounds of particulate matter are eliminated in a 24-hour port call.
Its half-life the time taken for half the radioactive atoms in a sample to decay is 109 minutes, compared with two minutes for oxygen-15, ten minutes for nitrogen-13 and 20 minutes for carbon-11.
Future versions, they believe, should also be able to cope with pollutants that do not contain carbon, such as oxides of nitrogen.
" London is thought to have the highest levels of nitrogen dioxide of any capital city in the EU, with levels on some of London's busiest roads, such as Brixton Road and Putney High Street, currently more than triple legal limits, " he said.
One of the worst disasters in U.S. history involving a form of ammonia occurred in April 1947 when a ship loaded with ammonium nitrate -- a solid fertlizer composed of ammonia and nitrogen -- caught fire while docked in Texas City, Texas, in April 1947.
But how we do it is take the bench-top physics class model, where you mix nitrogen and ice cream in a bowl and stir it up with a spoon.
The national temperament is changing with the U.S. Congress enacting tougher rules on sulfur dioxide, nitrogen oxide and mercury while the U.S. Environmental Protection Agency is beginning to clamp down on greenhouse gases.
