Best research work in the area of wine growing

...wo or four days after the recovery irrigation, the gaseous interchange was measured, comparing it with plants that had not suffered stress. From their results the researchers deduced that "the occurrence of a period of hydric stress modifies the hydric relations of the grapevine even when irrigation had bee...

Triple threat polymer captures and releases

...e release of these guests ?fragrance molecules ?as gaseous small molecules from the polymer across the network of the host material. "We found that the temperatures at which the guests left the material were dependent on the composition of the host, and when the release of the small guest molecules was mon...

Microbe fixes nitrogen at a blistering 92 C

...amino acids and proteins. To be used by organisms, gaseous nitrogen must be converted to other compounds, or ...earth to cause the fixed nitrogen to revert to its gaseous form. Venting water hotter than 30 C contains very little nitrate so organisms in areas where the su...

Research to spotlight carbon monoxide benefits

... to administer carbon monoxide in its normal toxic gaseous form; rather we want to develop molecules that will release it in a sort of slow trickle feed. We aim to make tuneable compounds which allow you to alter the rate at which carbon monoxide is released, which could be important in different bioapplicat...

New sensor detects gaseous chemical weapon surrogates in 45 seconds

...oratory, has demonstrated QPAS's ability to detect gaseous nerve agent surrogates. In one test, researchers used diisopropyl methyl phosphonate (DIMP), which is a chemical compound that's similar to sarin. QPAS detected DIMP at the sub-part-per-billion level in less than one minute. The miniscule level is si...

New findings blow a decade of assumptions out of the water

...ty to where it is being pulled back apart into its gaseous state by a different kind of micoorganism, he says... Eventually the fixed nitrogen is returned to its gaseous state, a process called denitrification. Scientists have known for several decades that denitrificat...
