Corrosion inhibitor distribution on abrasive-blasted steels.

Hypothesis: Abrasive-blasted steel surfaces exhibit a complex, multi-substrate environment. Adsorption to contaminant substrates can reduce the amount of available corrosion inhibitor and decrease its efficiency. Knowledge of where inhibitors preferentially adsorb is required.

Hydroboration as an Efficient Tool for the Preparation of Electronically and Structurally Diverse N→B-Heterocycles.

Ladder-type organoboranes featuring intramolecular N→B coordination have been prepared through hydroboration of a 2-(ortho-styryl)pyridine (PhPy) with a series of hydroboranes, including 9H-9-borabicyclo[3.3.1]nonyl (9H-BBN), BH3 ⋅THF, HBCl2 ⋅SMe2 , HB(C6 F5 )2 , and a 9H-9-borafluorene derivative.
