    Amidinato Isopropylmethylamidosilylene-catalyzed hydroboration of carbonyl compounds by Lee, Jiawen, Fan, Jun, Koh, An-Ping, Cheang, Joslyn Wan-Jun, Yang, Ming-Chung, Su, Ming-Der, So, Cheuk-Wai

    Published 2022
    “…This study describes the use of an amidinato isopropylmethylamidosilylene [LSiN(Me)iPr] (1, L = PhC(NtBu)2) to catalyze hydroboration of carbonyl compounds. Compound 1 (loading: 5 – 10 mol%) was shown to be an efficient catalyst for the chemoselective hydroboration of aldehydes (average yield = 97 %, average TOF = 8.8 h-1) and ketones (average yield = 97 %, average TOF = 1.7 h-1) with pinacolborane (HBpin) in C6D6 at 90 oC to form borate esters. …”

    A microstrip grid array antenna for 60-GHz applications by Zhang, Bing, Zhang, Yue Ping

    Published 2013
    “…Measured results show that the impedance bandwidth (BW) of the GAA is 57.5-62 GHz (or 7.5% at 60 GHz), the 3-dB gain BW is 57.5-65 GHz (or 12.5 %) with the maximum gain 16.5 dBi at 60.7 GHz, vertical beams appear in broadside direction from 57 to 64 GHz, which agree well with simulated ones.…”
