Corrosion protection of AA2024 sealed anodic layers using the hydrophobic properties of carboxylic acids [PDF]
, 2009 The present study investigates the use of carboxylic acids as a post-treatment for sealed AA2024 anodised in tartaric–sulphuric acid electrolyte. Four monocarboxylic acids with different carbon chain lengths were tested ((CH3–(CH2)n–COOH with n=4, 8, 12 ...

The effects of carboxylic acids on the aqueous dispersion and electrophoretic deposition of ZrO2 [PDF]
Journal of the European Ceramic Society, Volume 32, Issue 1, 2012,
Pages 235-244, 2013 The agglomeration, electrokinetic properties and electrophoretic deposition behaviour of aqueous suspensions of ZrO2 with carboxylic acid additives were studied in comparison with conventional pH adjustment. It was found that citric acid imparted negative zeta-potential values and electrosteric stabilisation to particles in suspensions at all pH levels.

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.
