Well to be the more understandable as possible, if you need doing a chemical reaction with A+B you will have next AB.
Now, if you need 10x more AB you should need 10x A and 10x B.
If you have only for example 10xA and only 5x A never you will product 10x AB.
This is the same about increasing Lenr reactions by powders, if face to face each nickel atom (for example) you aren't able to put one hydrogen atom, no need in this case to use powders.
Only using high hydrogen pressure isn't enough.
Better should be using mono hydrogen liquid "if existed" at ambiant temperature and pressure.
Now it will be easier to use any solid or liquid catalyst as this one proposed.
Creating directly mono H "enough stable and excited" against the nickel, this is the way.
Never ICCF grandfathers or MFMP, Parkhomov and so many others understood that !
