2Tetranuclear yttrium and gadolinium 2-acetylcyclopentanoate clusters:Synthesis and their use as spin-coating precursors for metal oxide film formation for field-effect transistor fabrication显示文摘Lanthanide clusters [Ln_4(μ_3-OH)_2(η~2-accp)_4((μ-O)-η~2-accp)_6](Ln = Y(4),Gd(5); accp = 2-acetylcyclopentanoate) are accessible by treatment of [M(NO_3)_3·6 H_2 O](M = Y(1),Gd(2)) with 3 equiv. of Haccp(3) in presence of NaOH. The molecular structures of 4 and 5 in the solid-state are discussed. The thermal behavior of 4 and 5 was studied by TG under Ar and O_2, showing multistep decomposition processes. Additionally, DSC studies were carried out under an atmosphere of O_2. PXRD measurements of the TG residues confirm the formation of Ln_2 O_3.Spin-coating experiments were carried out with 4 and 5 for Ln_2 O_3 film deposition on silicon substrates. The layers are smooth, close and are of thicknesses of 18.87±1.13 nm and 25.59 ± 4.55 nm for Ln = Y and Gd, which was evidenced by SEM and EDX studies. Field-effect transistors were successfully fabricated by deposition of carbon nanotubes on top of the Y_2 O_3 films and formation of palladium contacts by a lift-off procedure. An on/off ratio of more than 4 orders of magnitude is achieved without considerable leakage currents. These results demonstrate the potential use of spin-coated Y_2 O_3 as a gate dielectric in electronic devices.Elaheh Pousaneh Andrea Preuβ Khaybar Assim Tobias Rüffer Marcus Korb Jana Tittmann-Otto Sascha Hermann Stefan E.Schulz Heinrich Lang 2018Journal of Rare Earths2018,36,10:1

5Mecillinam和羟氨苄青霉素/克拉维酸对产酶大肠杆菌的体外活性显示文摘Mecillinam(MPC)是6-β-脒基青霉酸衍生物。它通过优先与青霉素-结合蛋白2相结合而发挥其抗菌作用。结果在形成球状细菌细胞中其杀菌作用较其它抗生素更佳。本文旨在研究大肠杆菌产生的β-内酰胺酶是否足以导致对MPC耐药,以及不同的β-内酰胺酶是否对MPC耐药的影响亦不同。为了便于比较同时做了羟氨苄青霉素(AMPC)/克拉维酸(CV A)联用试验。用标准方法研究并鉴别产生TEM-1(RichmondⅢa型),Oxa-1(RichmondⅤ型)和染色体介导β-内酰胺酶(RichmondⅠ型)的大肠杆菌临床分离菌株,这些菌株均为最普遍的对氨苄青霉素族耐药(MIC大于64μg/ml)R.Marre E.Schulz 谢巾英 1990国外医药(抗生素分册)1990,11,1:0
