2-(Trimethylsilyl)ethoxymethyl chloride (SEM-Cl) is an organochlorine compound with the formula C 6 H 15 ClOSi, which was developed by Bruce H. Lipshutz during his work on the synthesis of N-methylmaysenine. It is used to protect hydroxyl groups, which can be cleaved with fluoride in organic solvents selectively under mild conditions. [1]
All of the editions of Perry's Chemical Engineering Handbooks. The 2018–2019 ninth edition was edited by Don W. Green and Marylee W. Southard [4] [5] Don Green, the handbook's editor-in-chief, holds a B.S. in petroleum engineering from the University of Tulsa, and M.S. and PhD.

An account of the early history of scanning electron microscopy has been presented by McMullan. [2] [3] Although Max Knoll produced a photo with a 50 mm object-field-width showing channeling contrast by the use of an electron beam scanner, [4] it was Manfred von Ardenne who in 1937 invented [5] a microscope with high resolution by scanning a very small raster with a demagnified and finely ...
The journal was established in 1909 as the Journal of Industrial & Engineering Chemistry. It was renamed in 1930 as Industrial & Engineering Chemistry before obtaining its current title in 1970. From 1911 to 1916 it was edited by Milton C. Whitaker. From 1921 to 1942 it was edited by Dr. Harrison E. Howe. [1]
The following outline is provided as an overview of and topical guide to chemical engineering: . Chemical engineering – deals with the application of physical science (e.g., chemistry and physics), and life sciences (e.g., biology, [[microbi logy]] and biochemistry) with mathematics and economics, to the process of converting raw materials or chemicals into more useful or valuable forms.
The environmental scanning electron microscope (ESEM) is a scanning electron microscope (SEM) that allows for the option of collecting electron micrographs of specimens that are wet, uncoated, or both by allowing for a gaseous environment in the specimen chamber.
The San Francisco 49ers on Monday suspended linebacker De'Vondre Campbell for the final three games of the regular season for refusing to play Thursday night against the Los Angeles Rams.. Niners ...
Engineering physics (EP), sometimes engineering science, is the field of study combining pure science disciplines (such as physics, mathematics, chemistry or biology) and engineering disciplines (computer, nuclear, electrical, aerospace, medical, materials, mechanical, etc.). [1] [2] [3]
