Often both Mercury Intrusion Porosimetry (MIP) (for pores in the range say 10nm to 150micrometers) and neutron tomography (say 100micrometer to a few millimeters) are carried out to assess pore size distribution of concrete specimens. Is there a way of getting the full range of pores (say from 10nm to a few mm) using neutron tomography with a single run?

the neutron imaging limit is about 1um in a good day, seems you need SEM analysis

Is there an ideal incubation time of RGO-modified SPCE before subsequent use, i.e., electrochemical characterization or further modification?

I notice that upon washing and air-drying of my RGO/SPCE surface and characterizing again via DPV, the current response towards ferricyanide probe significantly decreases. My worry is that the...

What is the relationship between pressure vacuum and pore water emptying?

Hello everyone, When I put a wet sample in a vacuum desiccator, the larger pores tend to empty. I would like to know if there is a relationship between vacuum pressure and the size of emptied...

If opposite charges attract each other, then why do neutrons and protons bind with each other, whereas electrons surround them in an atom?

According to science, like charges repel each other and opposite charges attract each other. But if you observe the structure of an atom, neutrons(neutral), and protons(positive) bind tightly with...
