A homogeneous synthesis of cellulose ethers comprises the steps of: dissolving cellulose in ionic liquid-containing solvent; adding at least one etherizing agent in absence of inorganic bases; adding the reaction mixture in a nonsolvent for cellulose ester obtained in the etherification reaction, and ...
Novel compositions of matter comprise homogeneous thermoset copolymers resulting from the reaction between a poly(vinyl benzyl ether) of a polyphenol and a dicyanate ester of a polyether of a polyphenol may be used as components in laminates which are employed in electronic circuit boards. The ...

Electroporation was detected with a fluorescent calcium indicator Fura-2 acetoxymethyl ester (AM) (ThermoFisher Scientific). Fura-2 AM is a cell-permeant form of the dye that enters the cell and is cleaved by cell esterases into a cell-impermeant form. When cells are electroporated, calcium ...
An hydroxyl-functionalized analyte, analyte derivative or analyte analog can be converted to the corresponding p-toluenesulfonate ester, trifluoromethanesulfonate ester, bromide, or iodide, and then reacted with thioacetic acid to introduce an acetyl-protected thiol. The acetyl protecting group can be...
