Publikováno v: Bulletin of the Chemical Society of Japan. 73:1735-1748

Organotin compounds [Tp*SnCl3-nBun] (2: n = 1; 3: n = 2) having a Tp* ligand (Tp* = tris(3,5-dimethylpyrazol-1-yl)hydroborate) are useful reagents for introducing a Tp* ligand on Group 4 and 5 metals and chromium. The test reactions of these organoti

Publikováno v: Journal of Wind Engineering and Industrial Aerodynamics. 83:503-514

Finding a method to suppress aeroelastic vibrations of a bridge deck is an important research to construct a superlong suspension bridge with the main span longer than 2000 m. For this end, the boundary-layer control method was proposed and a fundame
