dimethylsulfoxide การใช้

• On contact with a liquid medium, diffusion of dimethylsulfoxide would occur, and a permanent solid polymer would precipitate.
• Uryx ?or Tegress ?( Bard Medical, Covington, GA ) was an ethylene vinyl copolymer dissolved in dimethylsulfoxide.
• Electron donors ( e . g . nucleophiles, Lewis bases ) for example dimethylsulfide and dimethylsulfoxide are believed to stabilize the carbocation.
• When the woman is ready to have her ovarian tissue returned, Fugger will thaw the strips of her ovary and replace the dimethylsulfoxide with water.
• Typically, a solution of in an organic solvent, such as dimethylformamide or dimethylsulfoxide, is applied over a titanium dioxide layer by spin coating.
• Transgene transmission in chickens by sperm-mediated gene transfer after seminal plasma removal and exogenous DNA treated with dimethylsulfoxide or N, N-dimethylacetamide.
• He will infuse these slices with dimethylsulfoxide, a chemical that replaces the water in the cells in order to protect them against damage when they are frozen.
• "' Dichlorotetrakis ( dimethyl sulfoxide ) ruthenium ( II ) "'describes coordination compounds with the formula RuCl 2 ( dmso ) 4, where DMSO is dimethylsulfoxide.
• The most important such solvents are dimethylsulfoxide, DMSO, and acetonitrile, CH 3 CN, as these solvents has been widely used to measure the acid dissociation constants of organic molecules.
• Researchers have found that eggs are more likely to survive freezing if they're cooled very rapidly, or treated with chemicals such as DMSO ( dimethylsulfoxide ), which protect cellular membranes.
• The mortality of rats caused by 5 mg / kg of ANTU is reduced when allylthiourea, isopropylthiourea, ethylenethiourea, or ethylidenethiourea are administered simultaneously with ANTU . Superoxide dismutase, catalase and dimethylsulfoxide all protect against the lung damage by ANTU ( although the results are diverse ).
• In " The Poisoner's Handbook, " for example, Maxwell Hutchkinson suggests that readers poison or kill Internal Revenue Service workers by filling out phony tax-return forms and lacing them with a mixture of ricin ( a poisonous protein ) and dimethylsulfoxide ( DMSO ) _ a concoction Hutchkinson claims is 100 percent lethal.
• Bacteria can also be made competent through a variety of chemical treatments including exposure to calcium ions, or a mixture of polyethylene glycol and dimethylsulfoxide, which make the cell membrane more permeable, leading to the uptake of the exogenous DNA . Another treatment method is the utilisation of electricity as the membrane-permeabilizing agent ( electroporation or electrotransformation ).
• Many different solvents are suitable, including sulfolane ( C 4 H 8 O 2 S ), furfural ( C 5 H 4 O 2 ), tetraethylene glycol ( C 8 H 18 O 5 ), dimethylsulfoxide ( C 2 H 6 OS ), and N-methyl-2-pyrrolidone ( C 5 H 9 NO ).
• In the commercial preparation of polyamideimides, the polymerization is carried out in a dipolar, aprotic solvent such as N-methylpyrrolidone ( NMP ), dimethylacetamide ( DMAC ), dimethylformamide ( DMF ), or dimethylsulfoxide ( DMSO ) at temperatures between 20-60 癈 . The byproduct HCl must be neutralized in situ or removed by washing it from the precipitated polymer.
