A monster's chain resistance indicates how quickly its chain meter fills up; a chain resistance of 70 is normal, and every 30 points modifies the chain bonus per hit by that same amount; thus, the chain meter of a monster with a chain resistance of 40 will increase at double speed (compared to 70), or triple speed with a chain resistance of 10; a chain resistance of 100 negates all chain ...

Cobaltite is an important ore of the element cobalt. It forms very interesting and unusual crystals rarely seen in the mineral kingdom, especially the icosahedral type. The name of Cobaltite, and its namesake cobalt, is derived from the …

 · The correlation between crystal facets and electronic configurations of perovskite is closely related to the intrinsic activity for water splitting. Herein, we proposed a unique molten-salt method (MSM) to manipulate the electronic properties of LaCoO3 by fine-tuning its crystal facet and atomic doping. LaCoO3 samples with oriented (110) (LCO (110)) and (111) (LCO (111)) …
