Electrochemical incineration of cresols: A comparative study between PbO2 and boron-doped diamond anodes [PDF]

open access: yes, 2009
The electrooxidation of aqueous solutions containing 5 mM of o-, m- and p-cresol at pH 4.0 has been investigated using a flow filter-press reactor with a boron-doped diamond (BDD) under galvanostatic electrolysis. All cresols are degraded at similar rate

DSSC Anchoring Groups: A Surface Dependent Decision [PDF]

open access: yes, 2014
Electrodes in dye sensitised solar cells (DSSCs) are typically nanocrystalline anatase TiO2 with a majority (101) surface exposed. Generally the sensitising dye employs a carboxylic anchoring moiety through which it adheres to the TiO2 surface.

Tandem dehydrogenation-olefination-decarboxylation of cycloalkyl carboxylic acids via multifold C–H activation

open access: yesNature Communications
Dehydrogenation chemistry has long been established as a fundamental aspect of organic synthesis, commonly encountered in carbonyl compounds. Transition metal catalysis revolutionized it, with strategies like transfer-dehydrogenation, single electron ...

The effects of carboxylic acids in aluminum anodizing [PDF]

open access: yes, 2017
Hard-anodized alumina coatings were formed in sulfuric acid at low temperature and high current density in the presence of carboxylic acid additives. Citric acid, trimesic acid, mellitic acid and ethylenediaminetetraacetic acid (EDTA) were utilized in ...

Ringed spherulitic and undulated textures in the nematic phase of a mixture of trans-4-hexylcyclohexanecarboxylic and benzoic acids

open access: yes, 2009
We present a polarising optical microscopy study of a liquid-crystal mixture of trans-4-hexylcyclohexanecarboxylic acid (C6) and benzoic acid. Both materials have carboxylic groups that can form dimers through hydrogen bonding. The mixture is nematic and

Recent Advances in the Synthetic and Mechanistic Aspects of the Ruthenium-catalyzed Carbon-heteroatom Bond Forming Reactions of Alkenes and Alkynes [PDF]

open access: yes, 2011
The group’s recent advances in catalytic carbon-to-heteroatom bond forming reactions of alkenes and alkynes are described. For the C–O bond formation reaction, a well-defined bifunctional ruthenium-amido catalyst has been successfully employed for the ...

Application of Computational Chemical Shift Prediction Techniques to the Cereoanhydride Structure Problem-Carboxylate Complications. [PDF]

open access: yes, 2017
Despite the vast array of techniques available to modern-day chemists, structural misassignments still occur. These misassignments are often only realized upon attempted synthesis, when the spectra of synthesized products do not match previously reported

Recycling of waste engine oils using a new washing agent [PDF]

open access: yes, 2013
This paper addresses recycling of waste engine oils treated using acetic acid. A recycling process was developed which eventually led to comparable results with some of the conventional methods.

Bi-acylation of cellulose: determining the relative reactivities of the acetyl and fatty-acyl moieties [PDF]

open access: yes, 2011
The global reaction between acetic anhydride and a fatty acid yields, at equilibrium, an asymmetric acetic-aliphatic anhydride in a medium containing finally: acetic-fatty anhydride, acetic anhydride, fatty acid, acetic acid and fatty anhydride.
