Understanding photosynthesis: How plants use catalytic reactions to split oxygen from water
Splitting hydrogen and oxygen from water using conventional electrolysis techniques requires considerable amounts of electrical energy. But green plants produce oxygen from water efficiently using a catalytic ...
Electrons in concert: A simple probe for collective motion in ultracold plasmas
(PhysOrg.com) -- Collective, or coordinated behavior is routine in liquids, where waves can occur as atoms act together. In a milliliter (mL) of liquid water, 1022 molecules bob around, colliding. When a bre ...
Scientists predict an out-of-this-world kind of ice
(PhysOrg.com) -- Cornell scientists are boldly going where no water molecule has gone before -- that is, when it comes to pressures found nowhere on Earth.
Supercooled: Water doesn't have to freeze until -55 F
(PhysOrg.com) -- We drink water, bathe in it and we are made mostly of water, yet the common substance poses major mysteries. Now, University of Utah chemists may have solved one enigma by showing how cold ...
Novel alloy could produce hydrogen fuel from sunlight
Scientists from the University of Kentucky and the University of Louisville have determined that an inexpensive semiconductor material can be "tweaked" to generate hydrogen from water using sunlight.
Disorder is key to nanotube mystery
Scientists often find strange and unexpected things when they look at materials at the nanoscale -- the level of single atoms and molecules. This holds true even for the most common materials, such as water.
Stanford team devises a better solar-powered water splitter (w/ video)
(PhysOrg.com) -- The process of splitting water into pure oxygen and clean-burning hydrogen fuel has long been the Holy Grail for clean-energy advocates as a method of large-scale energy storage, but the idea faces technical ...
Quantum model helps solve mysteries of water
Water is one of the most common and extensively studied substances on earth. It is vital for all known forms of life but its unique behaviour has yet to be explained in terms of the properties of individual ...
Snowball Earth: New study shows Antarctic climate even gripped the tropics
New details of a nightmare period on Earth with surface conditions as frigid as present-day central Antarctica at the equator have been revealed thanks to the publication of a study of ancient glacier water.
Findings on how electrons are solvated in water widen the range of potential influences on chemical reactions
Chemistry can be quite confusing. In order for the desired substance to be produced in a reaction or for two substances to interact - or not - chemists have to take into account a number of factors. Researchers ...
Study demonstrates desalination with nanoporous graphene membrane
Less than 1 percent of Earth's water is drinkable. Removing salt and other minerals from our biggest available source of water—seawater—may help satisfy a growing global population thirsty for fresh water ...
Atoms crowd and abandon catalyst's internal channel surfaces, changing its ability to drive reactions
Simple improvements to a bland-looking catalyst could change biofuel refining; the challenge is discovering how the catalyst truly works. Led by scientists at Pacific Northwest National Laboratory, a team ...
Why comets are like deep fried ice cream
Astronomers tinkering with ice and organics in the lab may have discovered why comets are encased in a hard, outer crust.
Chemical dial controls attraction between water-repelling molecules
Fear of water may seem like an irrational hindrance to humans, but on a molecular level, it lends order to the world.
