Material Inspired By Nature Could Turn Water Into Fuel
Scientists have theoretically designed a new material that could help supply the world with clean energy by turning water into fuel, using just the power of the sun. Chemists at the University of Read...
Mutant Plant Munches TNT, Could Help Solve Cleanup Problems
A new study suggests that a mutant variety of a cabbage relative thrives on TNT, pointing the way to a potentially elegant solution for millions of acres of contaminated land. The plant, Arabidopsis t...
Threats To Soil Productivity Threaten Food Security
In a review of recent scientific literature, the article, titled "Soil and Human Security in the 21st Century," outlines threats to soil productivity -- and, in turn, food production -- due to soil er...
Biogeochemistry
Biogeochemistry is the scientific discipline that involves the study of the chemical, physical, geological, and biological processes and reactions that govern the composition of the natural environmen...

Photocatalytic water splitting
Photocatalytic water splitting is an artificial photosynthesis process with photocatalysis in a photoelectrochemical cell used for the dissociation of water into its constituent parts, hydrogen (H2) a...
Lithium economy
The lithium economy is a concept analogous to the hydrogen economy, methanol economy, ethanol economy, electron economy, vegetable oil economy, or liquid nitrogen economy but where the energy storage ...
ATP test
The ATP test is a process of rapidly measuring actively growing microorganisms through detection of adenosine triphosphate, or ATP.
ATP is a molecule found in and around living cells, and as such ...
Cutting agent
A cutting agent is a chemical used to "cut" (dilute) illicit drugs with something less expensive than the drug itself.
The classical model of drug cutting (cf. Preble & Casey, 1969) refers to ...

Δ18O
In geochemistry, paleoclimatology and paleoceanography δO or delta-O-18 is a measure of the ratio of stable isotopes O:O (oxygen-18:oxygen-16). It is commonly used as a measure of the temperature of ...
Phytotoxicity
Phytotoxicity is a toxic effect by a compound on plant growth. Such damage may be caused by a wide variety of compounds, including trace metals, pesticides, salinity, phytotoxins or allelopathy.
