Rare-earth metal carboryne complexes LRE(C2B10H10)(thf)n [n = 2, RE Y (1a), Er (1b); n 1, (2); L 2-(2,5-Me2C4H2N)C6H4NC(Ph)N(2,6-iPr2C6H3)] were synthesized in good yields via either an alkane elimination reaction of rare-earth dialkyls LRE(CH2SiMe3)2 with 1 equiv o-carborane (o-C2B10H12) THF or a salt metathesis yttrium dichloride LYCl2(thf)3 Li2C2B10H10 toluene. They could be viewed as class ...

Estimating active earth pressure accurately is very important when designing retaining wall. Based on the unified strength theory and plane strain assumption, an analytical solution has been developed to determine the active lateral earth pressure distribution on a retaining structure with the inclined cohesive backfill considering the effect of the intermediate principal stress. The solution d...
