Why does disolving salt in water reduce its thermal capacity and conductivity?

How can the ions of the dissolved salt in water affect the thermal capacity and conductivity? What is the mechanism behind that? Many thanks in advance.

Does every nanofluid, solution, ionic liquid, or liquid has its unique radiation absorption?

It is well known that the peak absorption of gold nanofluids is at ~520nm wavelength (depends on the nanoparticle's size). Can another nanofluid (or other liquid, ionic liquid or a solution) have...

Is there a mathematical model to convert the electromagnetic field obtained by solving Maxwell's equations into heat (or temperature distribution)?

Hi, I am trying to simulate the heat generated by gold nanoparticles excited by light. I have found some researchers solve this problem by solving Maxwell's equation and the results are the...

fatal error

When I tried to energy minimization my system, I got fatal error as below. Fatal error: Atomtype opls_116 not found Although I've already added this line: ; include water #include "oplsaa.ff/spc.itp" to [molecultype] directive in my topology.

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
