Using ruthenium, a metal that is active in the presence of visible light, as a catalyst, Zhu produced an unexpected and unstable organic molecule
Since they are widely distributed in interstellar space, they might have played a key role in the production of many of the organic molecules
present at the time of the formation of the Solar System.
When that radiation passes through the dust in a molecular cloud or surrounding a dying star in the Milky Way, organic molecules
absorb some of the emissions and release that radiation at different wavelengths.
The organic molecules
found by the team were in a drilled sample of the Sheepbed mudstone in Gale crater, the landing site for the Curiosity rover.
These findings, led by Sandra Pizzarello, a research professor in ASU's Department of Chemistry and Biochemistry, suggest a far greater availability of extraterrestrial organic molecules
than previously thought possible, an inventory that could indeed have been important in molecular evolution and life itself.
Buried quickly and isolated from the water above by layers of fine-grained sediment, their porous skeletons gradually filled with minerals, but some of the pores containing organic molecules
were sealed intact.
The Herschel Space Observatory said Thursday that its telescopes heterodyne instrument for the far infrared -- one of Herschel's three innovative instruments -- demonstrates the gold mine of information that Herschel will provide on how organic molecules
form in space.
The third edition of this synthetic organic chemistry textbook for advanced undergraduate and graduate students has been expanded to include new information on transition metals such as novel reactions, new catalysts, ligands, reaction conditions and the applications in synthesis of complex organic molecules
Yet, the process or processes by which non-living organic molecules
turn into life are still unknown to science.
They recovered a variety of organic molecules
, including fatty acids such as those found in cell membranes.
The water is then run through a catalytic oxidizer to remove low-molecular-weight organic molecules
such as alcohols.
The possibility of occasional impacts from head disk collisions requires that the adhesive strength of the organic molecules
be increased while retaining the mobility of some of the molecules.
