Sentences with phrase «oxygen using sunlight»

The Joint Center for Artificial Photosynthesis, a federally funded lab based at the California Institute of Technology in Pasadena, said it has figured out how to use materials such as silicon and gallium arsenide in a process to split water into hydrogen and oxygen using sunlight.

Kesterites acting as photocatalysts might be able to split water into hydrogen and oxygen using sunlight, and to store solar energy in the form of chemical energy,» explains Schorr.

Not exact matches

«People found strains of bacteria that don't use food from the surface, don't use oxygen from the surface, and don't use sunlight from the surface.»

Besides collecting water and sediment samples, her team is using electronic instruments to measure temperature, salinity, dissolved oxygen, chlorophyll biomass, sunlight penetration, and other parameters at depths from 5 to 30 meters.

Sunlight and toxins do much of the damage, but the biggest culprit may be highly reactive byproducts created as cells use oxygen to turn sugar into energy.

Their study of photosynthesis in green sulfur bacteria, published in 2007 in Nature, tracked the detailed chemical steps that allow plants to harness sunlight and use it to convert simple raw materials into the oxygen we breathe and the carbohydrates we eat.

A few years ago, researchers led by Harvard University chemist Daniel Nocera devised what they call an artificial leaf that uses a semiconductor combined with two different catalysts to capture sunlight and use that harvested energy to split water molecules (H2O) into H2 and oxygen (O2).

Such a system is also called an artificial leaf or solar - fuel generator because in many ways it mimics the process which plants use to convert sunlight and CO2 into oxygen and fuel (sugars, carbohydrates).

All over our planet, plants photosynthesize, using their amazing and complex ability to harvest sunlight and channel it to convert carbon dioxide and water into oxygen and energy - rich carbohydrates.

Members of JCAP and JPL helped co-organize a workshop on the «production of oxygen and fuel from CO2 using sunlight», which was held at Caltech from June 28 - July 1.

Organisms like plants and algae use sunlight for photosynthesis to create oxygen and other important by - products.

These are generated in our body by its essential use of oxygen and on the skin by exposure to sunlight, airborne pollutants and some synthetic sunscreening agents.

Exposure to rancid food, polluted air, sunlight and electricity and also from cell phone or microwave use will also induce oxygen free radicals.

Be sure they understand that plants are essential to life in that they use sunlight to make oxygen, and are the source of all of our food, directly or indirectly.

For example, photosynthesis is the process by which a plant uses sunlight and oxygen to produce chlorophyll.

Free radicals are harmful biochemicals that can attack us from external sources (such as pollution, sunlight, etc.) or we make them ourselves as by - products of oxygen use.

Primary productivity — production of oxygen and carbohydrate, using sunlight and carbon dioxide and water — for this planet is barely partially understood, and changing fast due to climate change.

These include electrolysis, which uses electricity to split water into hydrogen and oxygen, and photoelectrochemical (PEC) cells, which use sunlight to do the same thing.

The trees use sunlight as fuel to transform water and carbon dioxide into oxygen and sugar.

«The Holy Grail of solar research is to use sunlight efficiently and directly to «split» water into its elemental constituents - hydrogen and oxygen - and then use the hydrogen as a clean fuel,» said Gray.

However, it is too chemically reactive to remain a free element in Earth's atmosphere without being continuously replenished by the photosynthetic action of living organisms, which use the energy of sunlight to produce elemental oxygen from water.

With this research there holds the promise of developing cells to separate hydrogen and oxygen from water using sunlight.
