Great news for all chemistry students , AI will probably not replace you (yet), although generative AI can help in first year maths and physics questions, it struggles with chemistry. Not so strange maybe, it's less straight forward and exact.
At the same time GPT4 is amazing in analysing questions just from looking at a picture. #GPT4 #experiments #generativeAI #ai #chemistry

Their conclusion: "imidazolium-containing ionomers intrinsically promote HER on Ag under CO2R conditions and have no measurable effect on CO2R to CO kinetics in contrast to expectations based on prior literature.”
Many papers use Sustainion™ membrane, seem to assume imidazolium must be present at cathode interface for good Faradaic yields.
So do we not need Sustainion™?

Lars Onsager Norwegian chemist whose development of a general theory of irreversible chemical processes gained him the 1968 Nobel Prize for Chemistry was born #OTD in 1903.
His first achievement was to modify the Debye-Hückel theory of electrolytic dissociation, to take into account Brownian movement. He also was able to formulate a general mathematical expression about the behaviour of nonreversible chemical processes that has been described as the “fourth law of thermodynamics.”

He is also known for his work involving free-radicals, many-membered rings, and organometallic compounds, as well as the development of Ziegler–Natta catalyst.
