Bruce L Yoder et al.
The Journal of chemical physics, 138(4), 044202-044202 (2013-02-08)
We present a new experimental configuration for the study of size-dependent, angle-resolved photoelectron and photoion spectra of weakly bound ultrafine aerosol particles targeted at particle sizes below ~20 nm. It combines single photon ionization by a tunable, table-top vacuum ultraviolet
Salma Parveen et al.
The journal of physical chemistry. A, 113(21), 6182-6191 (2009-05-09)
Theoretical calculations have been carried out using ab initio MP2 and B3LYP density functional methods to investigate the interaction between fluorinated dimethyl ethers (nF = 1-5) and water. Depending on the number of F atoms implanted on the dimethyl ethers
Xiao Liang et al.
The journal of physical chemistry. B, 115(25), 8199-8206 (2011-06-10)
The acid-catalyzed hydrolysis of dimethyl ether (DME) to methanol was examined using ab initio density functional metadynamics simulations. Diffusion of the acid proton from the aqueous medium, leading to the formation of a protonated DME, is 12.3 kcal mol(-1) activated
Kazuyuki Oshita et al.
Chemosphere, 78(9), 1148-1154 (2010-01-02)
We investigated whether polychlorinated biphenyls (PCBs) and water could be simultaneously removed from river sediment by solvent extraction using liquefied dimethyl ether (DME) as the extractant. DME exists in a gaseous state at normal temperature and pressure and can dissolve
M Naqvi et al.
Bioresource technology, 101(3), 937-944 (2009-09-22)
There is great interest in developing black liquor gasification technology over recent years for efficient recovery of bio-based residues in chemical pulp mills. Two potential technologies of producing dimethyl ether (DME) and methane (CH(4)) as alternative fuels from black liquor
