MALDI-TOF MS for the Identification of Cultivable Organic-Degrading Bacteria in Contaminated Groundwater near Unconventional Natural Gas Extraction Sites

open access: yesMicroorganisms, 2017
Groundwater quality and quantity is of extreme importance as it is a source of drinking water in the United States. One major concern has emerged due to the possible contamination of groundwater from unconventional oil and natural gas extraction ...

Noncovalent Binding of the Halogens to Aromatic Donors. Discrete Structures of Labile Br\u3csub\u3e2\u3c/sub\u3e Complexes with Benzene and Toluene [PDF]

open access: yes, 2001
Precise molecular structures resulting from the noncovalent interaction of Br2 with benzene (and toluene) reveal the unusual localized bonding to specific (one or two) carbon centers in prereactive complexes leading directly to the transition states for ...

Diffusion of a hydrocarbon mixture in a one-dimensional zeolite channel: an exclusion model approach

open access: yes, 2009
Zeolite channels can be used as effective hydrocarbon traps. Earlier experiments (Czaplewski {\sl et al.}, 2002) show that the presence of large aromatic molecules (toluene) block the diffusion of light hydrocarbon molecules (propane) inside the narrow ...

Ignition delay times of benzene and toluene with oxygen in argon mixtures [PDF]

open access: yes
The ignition delay times of benzene and toluene with oxygen diluted in argon were investigated over a wide range of conditions. For benzene the concentration ranges were 0.42 to 1.69 percent fuel and 3.78 to 20.3 percent oxygen. The temperature range was

Encapsulation of DNA by cationic diblock copolymer vesicles

open access: yes, 2004
Encapsulation of dsDNA fragments (contour length 54 nm) by the cationic diblock copolymer poly(butadiene-b-N-methyl 4-vinyl pyridinium) [PBd-b-P4VPQ] has been studied with phase contrast, polarized light, and fluorescence microscopy, as well as scanning ...
