Interaction of solid organic acids with carbon nanotube field effect transistors [PDF]
Chem. Phys. Lett. 430 (2006) 75, 2006 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

Monte Carlo simulation of molecular dynamics for amino acid production from carboxylic acid via C-14 beta-decay [PDF]
, 2021 To study the chemical origin of life, we investigated the amino acid production probability from radiocarbon (C-14)-containing carboxylic acid via beta-decay using a newly developed Monte Carlo simulator for molecular dynamics calculation. Using the simulation, we calculated the dynamical trajectory of N-14 recoiled via C-14 beta-decay in [3-C-14 ...

Unravelling the surface chemistry of metal oxide nanocrystals, the role of acids and bases [PDF]
, 2014 We synthesized HfO2 nanocrystals from HfCl4 using a surfactant-free solvothermal process in benzyl alcohol and found that the resulting nanocrystals could be transferred to nonpolar media using a mixture of carboxylic acids and amines.

Probing Functionalities and Acidity of Calcined Phenylene-Bridged Periodic Mesoporous Organosilicates Using Dynamic Nuclear Polarization NMR, Diffuse Reflectance Infrared Fourier Transform Spectroscopy, and X-ray Photoelectron Spectroscopy [PDF]
J. Phys. Chem. C 124 (2020) 6110-6120, 2020 Owing to their high surface area, their high stability, and their hydrophobicity, periodic mesoporous organosilica (PMO) materials represent promising catalytic support for environmentally friendly chemical processes in water. We investigate here how the calcination of PMO material with benzene linkers (PMOB) allows its functionalization.

An enhanced procedure for measuring organic acids and methyl esters in PM2.5 [PDF]
Atmospheric Measurement Techniques, 2015 A solid-phase extraction (SPE) pretreatment procedure allowing organic acids to be separated from methyl esters in fine aerosol has been developed. The procedure first separates the organic acids from fatty acid methyl esters (FAMEs) and other nonacid ...

Synthesis of 13C—O-labelled tertiary alkanoic acids by the Koch-haaf-reaction [PDF]
, 1981 Good yields of tertiary alkanoic acids are obtained from the Koch-Haaf-synthesis even when only stoichiometric amounts of carbinol and HCOOH are used. This offers a new approach to 13CO-labelled tertiary alkanoic acids.
