Translated by the DART ATP as 29 km/h, 30 km/h, 50 km/h, 50 km/h, 75 km/h and 100 km/h speed limits. Diesel drivers have to select the appropriate carrier frequency when moving to or from an electrified area. "Carrier 1" (50 Hz) is used in non-electrified areas and "Carrier 2" (83.3 Hz) is used in electrified areas.

Halide abstraction from BrGeR 3 (R = [C 6 H 3 (O t Bu) 2] 3) using Ag + [Al(Opftb) 4]- yields the germyl cation Ge[C 6 H 3 (O t Bu) 2] 3 +, stabilized by bulky ligands and a weakly coordinating PFAA anion. [20] The aryl substituents are oriented in a paddlewheel confirmation about the germanium center and possess shortened Ge-C bonds due to ...
The reaction involves no changes in the oxidation state of the metal and can be viewed as splitting H 2 into hydride (which binds to the metal) and proton (which binds to the base). ML n x+ + base + H 2 ⇌ HML n (x-1)+ + Hbase + Such reaction are assumed to involve the intermediacy of dihydrogen complexes. Bifunctional catalysts activate H 2 ...
