Although the reasons are not obvious - a nanoparticle geometry of 147 individual particulates (atoms) is favored in nature as a most efficient packing factor. This geometry is based on 12 icosahedrons surrounding and linked to the 12 vertices of a central icosahedron - and this structure notably turns up in nanoparticles of palladium, nickel, iron, gold, and silver - all metals which are associated with LENR or hydrogen densification.
There is also the famous "magic circle" of Hui in ancient Chinese mathematics which is coincidental other than to indicate that there is something special about recurring numbers in spatial geometry, such as binding sites using Platonic solids as the starting point. https://en.wikipedia.org/wiki/Centered_icosahedral_number https://en.wikipedia.org/wiki/Magic_circle_(mathematics) But the main point of this thought (wrt the recent breakthrough claim of Mizuno) is that in practice - achieving an optimal geometry with a palladium surface coating may be difficult if not impossible - at least in other ways than the one which Mizuno has found and shared with the World - his "Aladdin technique" of rubbing. Perhaps a plated film will be too uniform, and larger particles will not work at all - thus the method and technique of rubbing is extremely important to achieve the optimal size. I suspect this one detail will be the most critical issue that turns up in assessing the replication attempts, some of which will be coming in soon. If we have a failed experiment- was the palladium applied correctly to maximize the number of nanoparticles which consist of 147 atoms? It could be that simple. As it turns out... this number 147 is the approximate number of atoms involved in the Coulomb explosion as documented by Miley and Hora et al. This points to another route for thermal gain, aside from nuclear fusion. If the optimal sized palladium nanoparticle is fully loaded - it too should have about 147 deuterons in weak bonds or if loaded on the external layer only - there are 99 such deuterons. It is not ruled out that sequential loading and unloading at a very high rate, thousands of times per second, can provide high thermal gain without the need for actual fusion, or in addition to fusion. The mass loss behind the energy gain would derive from nuclear coupling - QCD strong force dynamics. Jones
