Methylated cycloalkanes fuel a novel genus in the Porticoccaceae family (Ca. Reddybacter gen. nov)

open access: yesEnvironmental Microbiology, Volume 25, Issue 12, Page 2958-2971, December 2023., 2023
Metabolic reconstruction of Reddybacter genome. Abstract Cycloalkanes are abundant and toxic compounds in subsurface petroleum reservoirs and their fate is important to ecosystems impacted by natural oil seeps and spills. This study focuses on the microbial metabolism of methylcyclohexane (MCH) and methylcyclopentane (MCP) in the deep Gulf of Mexico ...

Interaction of solid organic acids with carbon nanotube field effect transistors [PDF]

open access: yesChem. Phys. Lett. 430 (2006) 75, 2007
A series of solid organic acids were used to p-dope carbon nanotubes. The extent of doping is shown to be dependent on the pKa value of the acids. Highly fluorinated carboxylic acids and sulfonic acids are very effective in shifting the threshold voltage and making carbon nanotube field effect transistors to be more p-type devices.
