  At the nano-scale, surface phenomena such as attractive VdW forces strongly
dominate; explosions may well be thought impossible. We confirm nano explosions
that are important for a fractal (hierarchical, scale invariant) pore
structure, greatly increasing pore access. Analyzing only microscope images,
image analysis and statistical error reduction algorithms alone provide
conclusive evidence of explosively expelled material. The results reconfirm
that computer image recognition and statistical analysis are a widely
applicable and inexpensive technique for determining parameters which are
otherwise unavailable, such as the densities of single nano shapes. The
explosion mechanism explains optimum calcination temperatures for
cobalt-hydroxide and why slow heating optimizes porosity. Slow heating
increases the accessible surface area by 60% with this supercapacitor material.
