Comparison of external calibration and isotope dilution methods for iodine determination in foods by inductively coupled plasma mass spectrometry [PDF]
This study sought to validate the external calibration curve (CAL) method for iodine analysis in 26 selected foods and then to compare the test result with the isotope dilution mass spectrometry (IDMS).

Tetramethylammonium hydroxide is used in the electronic industry during the photolithography process to produce memories. The effluent produced in this process must be treated before discharging due its toxicity. The aim of this research is to evaluate the feasibility of biological treatment to remove this molecule from the effluent by aerobic process ...

Effective suppression of interface states in recessed-gate MIS-HEMTs by TMAH wet etching
The effect of tetramethylammonium hydroxide (TMAH) treatment prior to gate dielectric deposition on the performance of recessed-gate AlGaN/GaN metal-insulator-semiconductor high electron mobility transistors (MIS-HEMTs) was investigated.

An alternative method for the determination of siloxane activities toward basic equilibration catalysts [PDF]
The method used is based on the well-known fact that siloxane equilibrates once formed, do not change their compositions unless some siloxane compound is added, in which case new equilibrium compositions appear.

Mathematical modeling of transesterification process kinetics of triglycerides catalyzed by TMAH [PDF]
Biodiesel is a renewable fuel mainly produced by methylation of triglycerides of vegetable oils or animal fats. The production processes nowadays are particularly based on the utilization of inorganic alkali catalysts. However, it has been proved that an
