This book probes deep into the science and engineering of methanol production. Its authors include Professor Olah, a 1994 Nobel Prize winner in Chemistry for his work on hydrocarbon chemistry in superacids. If you seek a textbook or an easy to understand technical assessment of methanol, this is the book for you. It contains overviews of oil, natural gas,(More)
We report the first X-ray diffraction on gramicidin in its membrane-active form by using uniformly aligned multilayer samples of membranes containing gramicidin and ions (T1+, K+, Ba2+, Mg2+ or without ions). From the difference electron density profiles, we found a pair of symmetrically located ion-binding sites for T1- at 9.6 (+/- 0.3) A and for Ba2+ at(More)
Atmospheric Pollution by Mark Z. Jacobson Course Description. The effects of human activity on atmospheric composition, focused on global warming, the carbon cycle, air pollution, and the ozone layer. Fundamentals of atmospheric chemistry (spectroscopy, kinetics, isotopic analysis, and biogeochemical cycles) are related to the modern understanding of(More)
Parrots (Psittaciformes) are among the most threatened bird orders with 28 % (111 of 398) of extant species classified as threatened under IUCN criteria. We confirmed that parrots have a lower Red List Index (higher aggregate extinction risk) than other comparable bird groups, and modeled the factors associated with extinction risk. Our analyses included(More)
Primer pairs were designed for 41 di-nucleotide microsatellite loci identified from across the full genome of the Scarlet Macaw (Ara macao). We present the best 30 polymorphic loci with 5–22 alleles, 3–14 effective alleles and expected heterozygosities of 0.669–0.930. These markers will facilitate population genetic and conservation genetic studies on(More)
Recent conferences on future technology have lead to dreaming of the &#8220;perfect&#8221; on-line documentation system for the paperless office. This panel discussion on <underline>Using the New Technology</underline> will present specifications for one such &#8220;perfect&#8221; system. The audience will be invited to consider what changes and(More)
By the use of the general TRIPLE resonance technique, " ' the values of 1.544 and 0.051 mT are found to have the same sign, which is opposite to that of 0.1 17 and 0.065 mT. Fig 2. ESR spectrum of the radical cation 7 generated from 1 o r 3 (CH2C12,-40°C). Top: complete spectrum. Bottom: part of the spectrum including the three central groups of lines at a(More)
Fluoroform (CF(3)H), a large-volume by-product of the manufacture of Teflon, refrigerants, polyvinylidene fluoride (PVDF), fire-extinguishing agents, and foams, is a potent and stable greenhouse gas that has found little practical use despite the growing importance of trifluoromethyl (CF3) functionality in more structurally elaborate pharmaceuticals,(More)
Genetic tagging is the unique identification of individuals by their DNA profile. This technique is well established in mammals, but it has not yet been widely adopted for birds. Extraction methods for minute amounts of DNA even enable the use of genetic tagging from non-invasive samples, like hair, scat, or feather. In this study, we evaluate the potential(More)
the alkylation reaction. We (23) and others (24) observed similar carbon isotope effects in ruthenium-catalyzed C–H insertion reactions, where C–C bond formation has been proposed as the rate-limiting step. On the basis of these results, we propose a mechanism involving a cationic Ru-alkenyl species 22, which is initially formed from the reaction of 1 with(More)
