Kinetic analysis of biological degradation for tetramethylammonium hydroxide (TMAH) in the anaerobic activated sludge system at ambient temperature

Biochemical Engineering Journal, 2016
Abstract With rapid development of thin-film transistor liquid crystal display industries, improvements of the wastewater treatments for spent developing fluid (Tetramethylammonium hydroxide (TMAH)) is essential. As an alternative to the conventional aerobic processes, an anaerobic process in ambient temperature composed of a suspended sludge reactor

Swelling and dissolution kinetics of poly(4-hydroxystyrene) in tetrabutylammonium hydroxide (TBAH) aqueous solutions studied by quartz crystal microbalance (QCM) method—in comparison with tetramethylammonium hydroxide (TMAH) aqueous solutions

Japanese Journal of Applied Physics, 2022
The dissolution (including the formation of a transient swelling layer) of a resist polymer is key to realizing ultrafine patterning. However, the details of the dissolution of resist polymers remain unclarified.

Decontamination of tetramethylammonium hydroxide (TMAH) splashes: promising results with Diphoterine^®in vitro

Cutaneous and Ocular Toxicology, 2010
Tetramethylammonium hydroxide (TMAH), used in microelectronic industries and research and development, has both corrosive properties and systemic toxicity. Two fatal TMAH occupational exposure cases have been published. Studies comparing initial TMAH decontamination with Diphoterine versus tap water were performed: an in vitro pH titration study and an

Effects of tetramethylammonium hydroxide (TMAH) treatment on interfibrillar structure of lyocell (TENCEL) fibres

Materials Research Innovations, 2010
AbstractLyocell fibres were treated with tetramethylammonium hydroxide (TMAH) up to 1·5M, which was demonstrated to be more effective than LiOH, NaOH and KOH treatments at the same concentration in the sole interfibrillar swelling region. The porous structure of fibres was studied by inverse size exclusion chromatography to identify mean pore diameter,

Step-and-terrace surface formation on (001) β-Ga2O3 by wet etching using 2.38 wt% tetramethylammonium hydroxide (TMAH) lithographic developer

Japanese Journal of Applied Physics
Wet etching of (001) β-Ga2O3 was performed using a standard lithographic developer—an aqueous solution of 2.38 wt% tetramethylammonium hydroxide (TMAH)—at moderate temperatures of 25 °C and 40 °C.
