The PdO-coated layer of Pd-nano-particle may arrange fractal nano-dips on its surface when D(H)-gas
is charged and de-oxidation molecules (D2O or H2O) are released.
Fractal nano-dips may make local deep adsorption potentials, through which rapid penetration of D-atoms
(ions) into deeper Pd-local lattice (Bloch potential) O-sites of nano-particle may be induced, to realize
full or over-full D(H) loaded state (x>1.0) of PdDx in a short time of the Phase-I process. Formation of
D-clusters, such as 4D/TSC on surface may be enhanced at nano-dips. A phenomenological model of quasi-free
D-motion under constraint of the Bloch potential within a global mesoscopic potential well is proposed
for the Phase-II phenomena, where nuclear heating by 4D fusion reactions may rather steadily take place.
Generation of collective mesoscopic potential well (CMPW) will make a Pd nano-particle with PdO working
as "mesoscopic catalyst" which realizes very large D(H)-loading ratios and anomalously large chemical heat
releases both for H-gas and D-gas loading.

Discussions with brief summary of the Kobe group's experiments are given. Phenomenological
modeling on mechanisms are made for explaining observed anomalies in D(H)-overloading and high
heat-power release rates from nano-palladium-particles and binary metal PdNi nano-particles
dispersed in/on ZrO2 ceramics supporter flakes under D(H)-gas loading at room temperature. Roles
of PdO layer and Pd-ad-atoms (incomplete outer shell) of nano-Ni-core are modeled as mesoscopic
catalysts which have sub-nano-holes (SNH) on nano-particle-surfaces. SNH may realize strong
sticking force for D(H)-gas to dissociate and diffuse rapidly into inner local lattice sites.
During the beginning process, 4D/TSC cluster fusions with 1watt/g-Pd(or PdNi) may happen on
surface. By the very over-loading (x>>1) states in the later region of Phase-I and in the
Phase-II after saturation, TSC formation inside nano-particles may be strongly enhanced by the
non-linearly coupled QM oscillation (high free energy states of deuterons in local Bloch
potentials) under the deep mesoscopic global collective potential well.
