AI Thread Summary
The discussion focuses on the production and synthesis methods of iron oxide nanoparticles, specifically magnetite (Fe3O4). For industrial production at a scale of approximately 1 kg per day, participants highlight various methods currently employed by chemical companies, emphasizing the need for efficiency and cost-effectiveness. Additionally, the conversation addresses laboratory-scale synthesis, with an interest in methods that can produce Fe3O4 nanoparticles under 10 nm in size. Participants share insights on the cheapest and easiest techniques for synthesizing these nanoparticles, reflecting on the balance between size, cost, and scalability in both industrial and laboratory settings.

Dear All:
I interested to know about the production/synthesis of iron oxide nanoparticles.
At present, which method/process is adopted in chemical companies for the production of magnetite (Fe3O4)? May be for production of 1 kg per day? The size may be around 50 nm.
I also wanted to know:
In laboratory one can prepare even 5 nm sized Fe3O4 nanoparticles. Can some one tell me about the cheapest and easiest method of preparing Fe3O4 nanoparticles (may be less than 10 nm size) in lab scale?
Thank you for your help.
Regards, Rajini.

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!!
