Methyl Ether-Derivatized Sterols and Coprostanol Produced via Thermochemolysis Using Tetramethylammonium Hydroxide (TMAH) [PDF]
Molecules, 2019 Sterols are widely distributed in nature from lipids in organisms to sediments. As a conventional method, extraction and derivatization with TMS have been applied for sterol analysis, requiring a long preparation time for gas chromatography−mass ...

Underwater Plasma‐Driven Decomposition of Tetramethylammonium Hydroxide (TMAH) Under Different Applied Field Strengths [PDF]
Plasma Processes and Polymers, Volume 23, Issue 3, March 2026.Underwater plasma efficiently degrades TMAH via in situ generation of reactive oxygen and nitrogen species. An underwater plasma accelerates mass transfer and radical attack on the quaternary ammonium cation. Time‐resolved analyses show decreasing TOC and conversion of organic carbon toward inorganic species, with concomitant formation of NO3–/NH4+ at ...

Wet etching of (−102) β-Ga2O3 with tetramethylammonium hydroxide (TMAH) [PDF]
Science and Technology of Advanced MaterialsWe 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 ...

The Origin of Efficiency in III-Nitride Micro-Light-Emitting Diodes. [PDF]
Adv Sci (Weinh)The images show panchromatic cathodoluminescence of III‐V materials, which reveal that AlGaInP red wafers, having fewer defects, support longer carrier diffusion lengths. Meanwhile, the density of defects increases with longer emission wavelengths in the InGaN system, illustrating how generated carriers pass through the material and how defects limit ...
