Mortality from Dermal Exposure to Tetramethylammonium Hydroxide

Journal of Occupational Health, 2008
. However, industrialTMAH is in the form of a concentrated strong alkalineand thus might have severe hazardous effects. We herepresent a mortality case caused by dermal exposure toindustrial TMAH at work.CaseA 22-yr-old male engineer was accidentally drenchedwith concentrated TMAH solution (25%, pH 13.5) whileconducting routine examination of the pipe ...

Quantitative analysis of cholesterol in 5 to 20 μl of plasma

Journal of Lipid Research, 1974
A gas–liquid chromatographic micromethod for quantitation of cholesterol in 20 μl of plasma was developed using 5α-cholestane as an internal standard, saponification with tetramethylammonium hydroxide–isopropanol, and extraction with tetrachloroethylene ...

Vanadium Cation Exchange-Driven Reconstruction of MOF-Derived Cobalt Hydroxide Electrodes for Electrocatalysis and Energy Storage. [PDF]

Adv Sci (Weinh)
A room‐temperature vanadium cation exchange strategy is developed to achieve simultaneous structural reconstruction and electronic/defect modulation of ZIF‐67 on nickel foam. The resulting mesoporous V20–Co(OH)2 electrode exhibits superior OER activity with low overpotentials and enhanced lattice oxygen participation.

Tetramethylammonium hydroxide thermochemolysis for the analysis of cellulose and free carbohydrates in a peat bog [PDF]

Journal of Analytical and Applied Pyrolysis, 2011
We have compared TMAH thermochemolysis with the classical method using acid hydrolysis for carbohydrates analysis in a peat core. Even if TMAH thermochemolysis does not analyse hemicellulosic carbohydrates and discriminate each individual carbohydrate sensu stricto, it allows the analysis of a cellulose pool hidden to acid hydrolysis and the specific ...

Comparison of tetramethylammonium hydroxide (TMAH), trimethylsulfonium hydroxide (TMSH), and trimethylphenylammonium hydroxide (TMPAH) thermochemolysis for in situ space analysis of organic molecules in planetary environments

, 2023
International audienceOne of the main objectives of present and future space exploration missions dedicated to astrobiology is the detection of organic molecules of interest for life (e.g. amino and fatty acids). With this aim, a sample preparation and a

Synthesis of Highly Purified Tetramethylammonium Hydroxide Solution

Denki Kagaku oyobi Kogyo Butsuri Kagaku, 1996
Tetramethylammonium hydroxide (TMAH) solution free from Cl ion was synthesized by electrolysis of the corresponding formate and hydrogencarbonate salts in an electrolytic cell with a cation exchange membrane. As formate salt was used as intermediate of TMAH synthesis, the TMAH solution was contaminated by a small amount of formic acid, while the high ...

Chloride Ions: Essential Agents for Achieving Spontaneous Delamination of MXene

Advanced Materials, EarlyView.
This work first identifies chloride ions as essential agents for spontaneous MXene delamination. Without Cl−, etched Ti3C2Tx remains multilayered; with Cl−, interlayer modification enables Li+ intercalation and osmotic swelling. The SPEED process couples HF‐assisted Al extraction, Cl−‐mediated interlayer expansion, and Li+‐driven swelling to produce ...

Sub‐Nanometer Cobalt on Tungsten Titanium Carbide MXene (W2TiC2Tx): An Electrocatalyst for Highly Efficient and Stable Alkaline Hydrogen Evolution at Industrial‐Scale Current Density

Advanced Materials, EarlyView.
A novel W2TiC2Tx MXene prepared through a MAX‐phase route supports sub‐nanometer Co for highly efficient alkaline hydrogen evolution. Strong Co–W interfacial interactions optimize hydrogen adsorption and catalytic activity, enabling low overpotentials of 63 mV at 10 mA cm−2, small Tafel slope of 44.3 mV dec−1, and exceptional durability at industrially
