Tetramethylammonium trifluoromethanesulfonate [PDF]

open access: yesIUCrData, 2016
The structure of tetramethylammonium trifluoromethanesulfonate, C4H12N+·CF3SO3−, was determined at 110 K in the monoclinic space group P21/m. The salt, which contains two cations and two anions in the asymmetric unit, has a network structure displaying C—

Methanogenesis from tetramethylammonium and choline in Methanococcoides methylutens Q3c requires a nonpyrrolysine monomethylamine methyltransferase homolog [PDF]

open access: yesFrontiers in Microbiology
Methanogenesis is a key biological process contributing to both global climate change and renewable energy via methane. Methylotrophic methanogenesis is an important, but often underappreciated, component of this process.

Thermo-acoustic investigation on mixtures of Tetramethyl ammonium hydroxide and caffeine in aqueous medium with the goal to understand their mutual interactions [PDF]

open access: yesBMC Chemistry
The present study explores, for the first time, the physicochemical and molecular interaction behaviour of tetramethylammonium hydroxide (TMAH)–caffeine (CAF) mixtures in aqueous medium.

Wet etching of (−102) β-Ga2O3 with tetramethylammonium hydroxide (TMAH) [PDF]

open access: yesScience and Technology of Advanced Materials
We investigated wet etching of (−102) β-Ga2O3 substrates using heated 25 wt% tetramethylammonium hydroxide (TMAH). The (−102) plane exhibited an etching rate that was one order of magnitude higher than those of the widely used (100), (010), (001), and ...

High-capacity water sorbent cycles without hysteresis under dry conditions [PDF]

open access: yesNature Communications
Sorbents capable of cycling water vapor under dry conditions are critical for applications such as atmospheric water harvesting, desiccation, and heat pumps; however, few existing sorbents demonstrate both hysteresis-free behavior and cycling stability ...

Tetramethylammonium (Z)-N′-cyanocarbamimidate

open access: yesIUCrData, 2021
In the structure of the tetramethyl ammonium salt of cyanourea, C4H12N+·C2H2N3O−, the N—C and O—C bond distances in the cyano and keto groups are in the normal range for such a moieties at 1.1641 (18) and 1.2550 (16) Å.

Swelling of TMA(tetramethylammonium)- and HDP(hexadecylpyridinium)-montmorillonites in water and toluene media: influence of the type montmorillonites

open access: yesMaterials Research, 2000
Organo-clays were prepared by exchange cations of the montmorillonite with tetramethylammonium (TMA)- and hexadecylpyridinium (HDP)-chloride. Two different montmorillonite types were studied.

Crystal Structures of New Ammonium 5-Aminotetrazolates

open access: yesCrystals, 2014
The crystal structures of three salts of anionic 5-aminotetrazole are described. The tetramethylammonium salt (P ) forms hydrogen-bonded ribbons of anions which accept weak C–H···N contacts from the cations.

Tetramethylammonium dimethyl (phenylsulfonylamido)phosphate(1−)

open access: yesActa Crystallographica Section E, 2012
The title compound, C4H12N+·C8H11NO5PS−, was obtained from tetramethylammonium hydroxide and dimethyl(phenylsulfonyl)amidophosphate. The tetramethylammonium cation has a slightly distorted tetrahedral configuration and the N&#8212 ...
