Cornell News: Former Cornellians win Nobels Roderick MacKinnon, a visiting researcher at Cornell High Energy Synchrotron Source (CHESS), was a co-recipient of the Nobel Prize in Chemistry. MacKinnon, a professor at The Rockefeller University and an investigator at the Howard Hughes Medical Institute, shared the chemistry Nobel with Peter Agre of Johns Hopkins University School of Medicine for work explaining how a class of membrane proteins, called channels, help to regulate cells. Engle, the Michael Armellino Professor in the Management of Financial Services at New York University's Stern School of Business, shared the economics prize with Clive W.J. Granger of the University of California, San Diego, for research on modeling the volatility of time-series data. www.news.cornell.edu /releases/Oct03/CHESS.MacKinnon.deb.html   (863 words)

Intermolecular Forces Many general chemistry textbooks say that London forces are always present because these are forces that are inherent in anything that has mass. Once you have identified the type of intermolecular forces present, you should be able to make predictions about boiling point (volatility). These last two forces are collectively known as Van der Waals forces and are in general very weak. www.richmond.edu /~egoldman/205/review/IF.html   (343 words)

Ionic liquid - Wikipedia, the free encyclopedia Due to their non-volatility, ionic liquids are generally considered as having a low impact on the environment and human health, and thus recognized as solvents for green chemistry. The notable characteristics of ionic liquids are their non-measurable vapor pressure, non-flammability, thermal stability, wide liquid range, and solvating properties for diverse kinds of materials. Another important feature of ionic liquids is their designability: miscibility with water or organic solvents can be tuned through sidechain lengths on the cation and choice of anion. en.wikipedia.org /wiki/Ionic_liquid   (1182 words)

Element 107 May Soon Find Place On Chemists' Periodic Table BERKELEY, CA — An international collaboration of radiochemists has used the PHILIPS cyclotron at the Paul Scherrer Institute (PSI) in Bern, Switzerland, to determine the volatility of bohrium, element 107 -- the heaviest element yet whose chemistry has been successfully investigated. In addition to PSI, Berkeley Lab, and UC Berkeley, collaborating institutions included the University of Bern in Switzerland, the Flerov Laboratory in Russia, the Forschungzentrum Rossendorf, Gesellschaft für Schwerionenforschung (GSI), and Technical University of Dresden in Germany, and the Japan Atomic Energy Research Institute in Japan. Element 110 Is Named Darmstadtium (August 20, 2003) -- At the 42nd General Assembly in Ottawa, Canada, the IUPAC Council officially approved the name for element of atomic number 110, to be known as darmstadtium, with symbol... www.sciencedaily.com /releases/1999/10/991005071519.htm   (1182 words)

ow Corning Adds Z-6172 Coupling Agent To Silane Solutions Dow Corning Z-6172 Silane is reactive in both free radical and hydrosilation chemistry, and has an organic reactive vinyl group and inorganic reactive methoxyethoxysilyl groups. Dow Corning Z-6172 Silane provides a lower volatility than other vinyl silanes for easier handling when compounding in a twin-screw extruder. The alkoxysilyl groups react to form siloxane bonds both to inorganic surfaces and materials, and also to other silane molecules to form a crosslinked network. www.chemicalonline.com /content/news/article.asp?docid={AF6BA5BC-5994-48FE-AAA0-B20E80850294}   (190 words)

Feng Wang's Personal Page Butane is also a protoype in organic and structural chemistry for structural (constitutional) isomers and conformational (stereoisomers) isomers. Butane is also added to gasoline in order to increase its volatility (evaporation rate) in cold climates. Butane exists as two isomers: n-butane is a fully hydrogenated linear chain of four carbon atoms: CH and i-butane, or isobutane, has the formula CH, and the systematic name 2-methylpropane. www.it.swin.edu.au /personal/fwang/Mom/Mom_butane.html   (1465 words)

Demonstrations - The Ether Trough Ether is a great solvent for many types of reactions in organic chemistry, but its flammability does pose some safety hazards. The combination of ether's high volatility, flammability, and vapor density can easily result in a fire is ether is used in a room in which open flames are present. Diethyl Ether, CH is an extremely flammable organic solvent, and also one of the first anesthetics to be discovered. www.angelo.edu /faculty/kboudrea/demos/ether_trough/ether_trough.htm   (337 words)

life and death of peter sellers - review at videovista Sellers' high-octane relationship with Edwards is well captured too, showing the off-screen clowning and volatility that underscored their chemistry. This was how Sellers felt about himself, and showing his identification with Chance sums up his condition as a lost soul behind a clown's mask in a way that is fresh and avoids cliché. But The Life And Death Of Peter Sellers comes good at the end, with the story of Sellers' quest to film the Jerzy Kosinski novel Being There, about Chance, an empty nobody who rises to become President of the USA, simply because he can be all things to all people. www.videovista.net /reviews/may05/ladpesel.html   (1074 words)

MSN Encarta - Alfred Nobel In 1867 Nobel achieved his goal; by using an organic packing material to reduce the volatility of the nitroglycerin, he produced what he called dynamite. His will provided that the major portion of his $9 million estate be set up as a fund to establish yearly prizes for merit in physics, chemistry, medicine and physiology, literature, and world peace.

Ester In organic chemistry and biochemistry esters''' are substances that have the functional group '''(R´-COOR") (the carbon is double-bonded to one oxygen atom and single-bonded to another) and consist of an alkane united with the residue of any oxygen acid, organic or inorganic. Unknown organic acids with low volatility can often be esterified into a volatile ester which can then be analysed using gas chromatography, gas liquid chromatography, or mass spectrometry. Esters mainly result from the condensation reactioncondensation (this is, a reaction that produces water) of a carboxylic acid and an alcohol. www.infothis.com /find/Ester   (877 words)

491T.asp During the nystatin project, the use of poly-trimethylsilylation as a vehicle for increasing the volatility, stability and solubility (in organic solvents) of such polyhydroxy compounds was developed and applied. Rod began work on nystatin in Manchester in collaboration with Arthur Birch and Carl Djerassi but finished it with his own group shortly after moving, as a Fellow, in 1966 to the Research School of Chemistry (RSC) at the Australian National University (ANU) in Canberra. Rod returned to Australia along with Birch as one of the foundation appointees and played a major consultative role in the design of, what is still, one of the most attractive and functional chemical research buildings in Australia. www.arkat-usa.org /ark/journal/2004/I10_Rickards/RR-491T/491T.asp   (2016 words)

The Royal Swedish Academy of Sciences said Wednesday in announcing the award that the academics devised new methods for measuring volatility, or the rate at which prices, interest and other economic variables move up and down. The prizes are presented to the winners on Dec. 10, the anniversary of Nobel's death in 1896. www.signonsandiego.com /news/business/20031008-1732-nobel-economics.html   (899 words)

Nuclear Science Division LDRD 2001 Annual Report The novel chemical separator is based on the expected high volatility of the tetroxides of hassium and consists of a chemical reaction chamber and the CTS. The successful chemical separation of hassium points the way to techniques that will be useful in studying the chemistry of other recently discovered elements. The team established that hassium forms a gaseous oxide similar to that of osmium, confirming that hassium, like osmium, is a member of group 8 of the periodic table and should be placed directly under it. www.lbl.gov /Publications/LDRD/2001/NSD.htm   (1753 words)

Chemistry / Physics Week 6 Syllabi Notes Ketones can be aromatic or alicyclic, are water soluble, are usually liquids, the lower wt ones are flammable, and as molecular wt increases volatility decreases, water solub decr and flammability decreases. Halogens - Halogens are chlorine, fluorine, bromine and iodine. Saturated hydrocarbons form substitution while alicyclic, aromatic, and certain hetercyclic compounds either add or substitute halogens. mna2001.tripod.com /chemphysics/chemphysicsnotes8.11.htm   (1753 words)
