Rohit, as you might know, typically emulsifiers are surface active agents (meaning they are active/accumulate at the surfaces/interfaces). As far as I know, the amount of emulsifier needed to stabilize a given emulsion is proportional to its interfacial area between the droplet and external phase fluids. So, for a given droplet phase fraction, you would need higher quantities of the emulsifier when you have many smaller droplets compared to that of the case where you have larger droplets.

what is the simplest definition of ion exchange capacity

What this unit identifies for the ion exchange capacity ca. 0.92 meq. g-1. I am a newcomer in the membrane area. I just started. I highly appreciate your help

Resistor definition in Piezoelectric bimorph with ANSYS workbench

Hello, good day! I am trying to simulate similar bimorph piezoelectric harvester with below commands. However, the output power doesn't change with resistor value. Please help to find the reason. ET,10,CIRCU94,0 !SET UP RESISTOR R,1,100000 !RESISTANCE VALUE TYPE,10 !SET ELEMENT TYPE E,1,2 !CREATE RESISTOR BETWEEN NODES 1 AND 2 Thanks in advance Regards,
