It's fluid in 4 centigrade degrees but when I put it in 37 centigrade it doesn't gelate after even 1 hour.
I checked the pH before putting the solution in the 37 centigrade. It was 6.3. I add up NaOH and take pH to 7 but it doesn't gelate again.
Hello, I want to know how to get the templates from the Elsevier official website (their last updated if exists)? I would like to know the steps if possible.
