Change is not made without inconvenience, even from worse to better. Richard Hooker, as quoted in the preface of Samuel Johnson's A Dictionary of the English Language Oh, so they have internet on computers now! Homer Simpson It is with great pleasure that I announce the rebirth of the former print journal of the Canadian Geriatrics Society as a new online publication, the Canadian Geriatrics Jo...
متن کاملConstraining the Environment of Ch+ Formation with Ch+ 3 Observations
The formation of CH+ in the interstellar medium (ISM) has long been an outstanding problem in chemical models. In order to probe the physical conditions of the ISM in which CH+ forms, we propose the use of CH3 observations. The pathway to forming CH + 3 begins with CH +, and a steady-state analysis of CH3 and the reaction intermediary CH2 results in a relationship between the CH + and CH3 abund...
متن کاملTurn and Face the Strange... Ch-ch-changes
Phase transitions are abrupt changes in the macroscopic properties of a system. Examples of the phenomenon are familiar: freezing, condensation, magnetization. Often these transitions are particularly dramatic, as when solid objects composed of the silvery metal gallium vanish into puddles when picked up (the temperature of the hand is just enough to raise gallium’s temperature past its melting...
متن کاملConversion of CH 4 to CH 3 OH : Reactions of COO + with CH 4 and D 2 , Co + with CH 30 D and D 20 , and Co + ( CH 30 D ) with Xe
The mechanisms and energetics involved in the conversion of CHI to CH3OH by COO+ are examined by using guided ion beam mass spectrometry. The forward and reverse reactions, COO+ + CH4 Co+ + CHgOH, the collisional activation of Co+(CH,OH), and the related reactions, COO+ + D2 Co+ + D20, are studied. It is found that the oxidations of methane and D2 by COO+, both exothermic reactions, do not occu...
متن کاملThe origin of the generalized anomeric effect: possibility of CH/n and CH/pi hydrogen bonds.
Ab initio MO calculations were carried out at the MP4/6-311++G(3df,3pd)//MP2/6-311++G(3df,3pd) level to investigate the conformational Gibbs energy of a series of methyl ethers CH(3)O-CH(2)-X (X=OH, OCH(3), F, Cl, Br, CN, C triple bond CH, C(6)H(5), CHO). It was found that the Gibbs energy of the gauche conformers is lower in every case than that of the corresponding anti conformers. In the mor...
