How does Reactive Oxygen Species (ROS) increases with increase in electrical conductivity?

we have prepared Mg doped ceria nanostructures, and characterized by LCR meter for electrical conductivity, at low frequencies the electric conductivity is almost same for all Mg dopant levels but...

How does AC conductivity of CeO2 nanostructures increase with increasing Mg doping concentration levels? Can anybody please answer with references?

We have undoped, 1,2 ,3,4 and 5% Mg doped Ceria nanostructures. in its dielectric results (using LCR meter), the AC conductivity is nearly constant at low frequencies and then increases above a...

Why almost every element would be metallized in sufficiently high pressure and low temperature?

(This statement is from wikipedia, BTW). What is so special about metallic bond that is limiting high-P low-T state of a matter (as long as individual atoms exist, not white dwarf of neutron star...

Mediation path analysis - Can I run two seperate models?

I am wanting to run a serial mediation model with 2 x IVs, 2 x MVs, and 3 DPs (all continuous). Is it problematic to run 2 different models for each IV, keeping the MVs and DPs the same in each...

Physical-chemical formation of stalactites/stalagmites. what promotes the formation/growth of these structures?

I know, or think I do, the basic idea behind these natural structures, as from what I know they form due to water dripping from the top leaving a salt deposit behind. But started to wonder about...
