Carboxyl and Amine Functionalized Carboranethiol SAMs on Au(111) : A Dispersion Corrected Density Functional Theory Study [PDF]
Phys. Rev. Materials 4, 095002 (2020), 2020 The morphological and electronic properties of isolated and monolayer phases of carboxyl- and amine-functionalized carboranethiols on unreconstructed Au(111) were determined using density functional theory calculations by including van der Waals interactions.

Discovery of the elusive carbonic acid (HOCOOH) in space [PDF]
ApJ, 954 3, 2023, 2023 After a quarter century since the detection of the last interstellar carboxylic acid, acetic acid (CH$_3$COOH), we report the discovery of a new one, the cis-trans form of carbonic acid (HOCOOH), toward the Galactic Center molecular cloud G+0.693-0.027.

An Ultrasensitive Picric Acid Sensor Based on a Robust 3D Hydrogen-Bonded Organic Framework
Biosensors, 2022 Hydrogen-bonded organic frameworks (HOFs), as a newly developed porous material, have been widely used in various fields. To date, several organic building units (OBUs) with tri-, tetra-, and hexa-carboxylic acid synthons have been applied to synthesize ...

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

Translational and reorientational dynamics in carboxylic acid-based deep eutectic solvents [PDF]
J. Chem. Phys. 160 (2024) 074503, 2023 The glass formation and the dipolar reorientational motions in deep eutectic solvents (DESs) are frequently overlooked, despite their crucial role in defining the room-temperature physiochemical properties. To understand the effects of these dynamics on the ionic conductivity and their relation to the mechanical properties of the DES, we conducted ...

Anodic aqueous electrophoretic deposition of titanium dioxide using carboxylic acids as dispersing agents [PDF]
Journal of the European Ceramic Society, Volume 31, Issue 6, 2011,
1041-1047, 2013 The dispersion of anatase phase TiO2 powder in aqueous suspensions was investigated by zeta-potential and agglomerate size analysis. The iso-electric point (IEP) of anatase was determined to be at pH 2.8 using monoprotic acids for pH adjustment. In comparison, it was found that the use of carboxylic acids, citric and oxalic, caused a decrease in zeta ...
