Thus, the boron-bearing rock system and the magnesian rocks are the foundation of the borate deposits, whereas regional metamorphism and migmatitization and tectonism are the necessary conditions.
Two new exocyclic ring-fused boron-dipyrromethene (BDP) dyes with benzo crown ether subunit at meso-position were prepared.Their spectroscopic and electrochemical properties were investigated.
By fuming with sulfuric-phosphoric acid mixture the residual hydrofluoride was then expelled,and boron was finally determined by curcumin spectrophotometry after distillation.
The project's objective is to " determine a form of boron or a boron-based chemical pathway that leads to implementation of boron in energetic compounds, especially fuels (solid and liquid)" .
" In addition, refractive index can also be used to 'invisibility', for example, objects with high borosilicate glass materials can also be 'invisible' when moving in glycerol with a refractive index close to its own, " Chu noted.
Boron additives in rocket fuels also failed. The combustion process involved proved unexpectedly complex, and the promised additional energy was not forthcoming.
