For the aerogel synthesis, the hydrogel undergoes a solvent exchange process in methanol stepwise and is found to have less shrinkage compared to other organic solvents. can the hydrogels be dried in supercritical co2?
From my own experience, ethanol or methanol solutions can be dried in supercritical CO2 without problems.
Thank you, sir, but do you have any reference with the miscibility curve of MeOH in co2.
What are your requirements for the drying, physical parameters? Why the SCF CO2? You can use others, including liquid nitrogen!
I got a thin band and a thick band i guess it would be the genomic DNA and the 260/280 ratio is 3.
