Aerogels - Supercritical Extractions?

AI Thread Summary
The discussion revolves around the challenge of extracting liquid from alcogel to create aerogel without a pressure chamber. The original poster seeks alternative methods for liquid extraction, emphasizing the potential value of developing non-supercritical fluid (SCF) processes for aerogel manufacturing. There is a suggestion to move the thread to an engineering section for better visibility, while acknowledging the complexity of the question and the likelihood of limited contributions on a public forum. The focus remains on finding practical solutions for aerogel production without conventional equipment.

I am trying to creat some aerogel. I can make the Alcogel but I do not have a pressure chamber and cannot extract the liquid from it. This site gives some information on the subject if you are interested:

Basically I just need help on extracting the liquid without using a pressure chamber. Any ideas?

Hello, this question fits better to engineering section, I think. Ask the moderator to move this thread to the proper location.
 
Gotta call it a perfectly reasonable question about chemistry --- whether anyone's going to contribute to developing processes for manufacture of aerogels that don't involve SCF methods (potential worth would be in millions) on a public domain forum is another question.
 
does anyone have an idea?
 

Thread 'Solubility of MgSO47H2O in water'

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
