Progress in designing magnetic polymers As modern alcnemists, organic chemists keep trying to make plastics more like metals -- either to conduct electricity or to serve as magnets. Although several [...]
The article cites research reported in the May 29, 2019, edition of the journal "Science Advances" concerning red ice on the dwarf planet that suggests the possibility of organic chemistry in Pluto's subsurface sea.
CARBON, HYDROCARBONS, CHEMICAL reactions, ORGANIC chemistry, UNIVERSITY faculty, and RUTGERS University (Piscataway, N.J.)
This article discusses research that has enabled chemists to alter the length of carbon chains by combining the power of two chemical reactions. This process might someday convert less-valuable carbon chains into a transportation fuel. Maurice Brookhart of the University of North Carolina at Chapel Hill and Alan S. Goldman of Rutgers University in Piscataway, New Jersey, and their research teams used two catalysts to promote reactions that together reclaimed short alkanes.

The article focuses on exploration of Saturn's largest moon, Titan. On Jan. 14, 2004 a flying saucer will parachute through the thick orange haze of a distant moon's atmosphere. Descending through the hydrocarbon smog, the probe could crash into an icy mountain, plop in a pool of organic goo, or dive into a methane ocean. Welcome to Saturn's largest moon, Titan, a place where organic chemistry appears to be a carbon copy of the infant Earth's just before life got a foothold. The saucer-shaped Huygens probe, named for the 17th-century Dutch astronomer who discovered Titan, has been riding piggyback on the Cassini spacecraft since it left Earth in October 1997. The craft arrived at Saturn on June 30 and has now embarked on a 4-year tour of the planet and its moons. Radar data from Cassini, taken during its first close flyby of Titan on Oct. 26, reveal dark patches that might be lakes of methane. Streaks imaged by visible-light cameras during that flyby could be caused by the flow of a hydrocarbon fluid or by wind eroding solid material. Titan has fascinated researchers for 6 decades, ever since astronomer Gerard Kuiper analyzed sunlight reflecting off the moon and discovered methane in its atmosphere. Yet even if Huygens doesn't plunge into a methane bath, its findings are likely to make quite a splash. It isn't just Titan's mix of organic compounds that intrigues planetary scientists. The moon also has reserves of frozen water that occasionally melt when struck by comets. The overall chemical cocktail appears to offer researchers the only available glimpse of conditions like those on Earth just before life got started. Before Huygens can take the big plunge, it will have to execute the big escape-separating from its mother craft, Cassini. On Christmas Day, engineers will radio a final set of commands for the parting.
MAGNETS, TECHNOLOGICAL innovations, RESEARCH, ORGANIC chemistry, and MAGNETISM
The article reports that advances are being made in the effort to develop organic, moldable magnets without the use of high temperatures. It is suggested that these magnets might also have the ability to be demagnetized if desired. The progress in and limitations of developing these magnets is presented.
ORGANIC chemistry, CHEMICAL reactions, ENANTIOSELECTIVE catalysis, ORGANOSILICON compounds, and ALCOHOL
The article reports on a new molecular catalyst which reduces a widely-used reaction into a one-step process. A silicon-based group is added to an alcohol site in many syntheses of organic molecules, says Marc L. Snapper of Boston College. Snapper and his colleagues report on the chiral of an alcohol group in the September 7, 2006 "Nature."
ORGANIC synthesis, ORGANIC chemistry, PETROLEUM, and ENVIRONMENTAL chemistry
The article explains the work team of researchers, led by Philip G. Jessop of Queens University (Ontario). They have synthesized two new, nitrogen-containing organic compounds that can transform upon exposure to common gases into surfactants, the clingy version of the new compounds, with the capability to revert to nonsurfactant forms. They are hopeful that the invention might someday aid in crude oil recovery. The team unveils the new work in the August 18th issue of "Science."
VOLATILE organic compounds, ORGANIC chemistry, PUBLIC health, ENVIRONMENTAL health, and LUNG diseases
The article focuses on para-dichlorobenzene, a volatile chemical used in household products which may interfere with lung capacity. Scientists at the National Institute of Environmental Health Sciences in Research Triangle Park, N.C., looked for effects of the chemical and 10 other volatile organic compounds commonly detected in U.S. residents. A potential but inconclusive correlation was found between the chemical and decreased lung capacity.
NANOSTRUCTURED materials, ORGANIC chemistry, FUNCTIONAL groups, CARBON, and MICROSCOPY
Reports that researchers have found a promising new way to attach molecules to carbon nanotubes. How this could facilitate the creation of harder materials and tinier electronic devices; Process which can attach clusters of atoms, known as functional groups, to as many as one out of every 20 carbons on a nanotube; Importance of this method, which was developed by Rice University researchers.
