I want to exchange my Au-citrate nanoparticle with two kinds of ligands :PEG-COOH and PEG-OH.
Which one is suppose to have more anionic charge density.
Here's the thing. I want to measure the surface charge of the alginate beads synthesized in our lab. It's about 400μm in diameter. I think most people uses zetasizer to examine the zeta-potential of small particles. But I think 400μm is probably too large for this kind of equipment to measure...
Say there is a vessel with constant volume. We know the EOS, moles and Cp of the vapor in it. How can we design an experiment to measure the (dS/dP) at constant V?
I think the idea is to transform (dS/dP)v into something that consists of Cp, V,P,T only. Then we can measure the small...
