Two metal coordination polymers, namely {[Co(1,3-BIP)(OBA)]·0.5H2O}n (SNUT-1) and [Co2(µ-η1:η1-O2)(1,3-BIP)2(PMA)]n (SNUT-2), where 1,3-BIP?=?1,3-bis(imidazol)propane, H2OBA?=?4,4′-oxybis(benzoate) and H4PMA?=?benzene-1,2,4,5-tetracarboxylic acid, were prepared by hydrothermal methods. Single-crystal X-ray analysis revealed that the structure of SNUT-1 consists of a 3D?→?3D twofold interpenetrating network that can be described as a 4-connected uninodal net with (65·8) topology. The structure of SNUT-2 consists of a 3D framework which can be described as a (4,5)-connected binodal net with (42·63·84·10) (33·42·5) topology. The gas adsorption properties of SNUT-1 and photocatalytic activity of SNUT-2 for the degradation of Rhodamine B have been explored.
In this paper, we present a novel nano-scale fully depleted silicon-on-insulator metal-oxide semiconductor field-effect transistor (SOI MOSFET). On-state current increment, leakage current decrement, and self-heating effect improvement are pursued in our proposed structure. The structure makes use of a buried insulator layer which consists of two materials to reduce the self-heating effect. On the other hand, to modify the sub- and super-threshold drain current, vertical trapezoidal doping distribution and additional side gate technique are employed. Our novel transistor is named dual material buried insulator vertical trapezoidal doping SOI MOSFET (DV-SOI MOSFET). We investigate the electrical performance and thermal behavior of the DV-SOI MOSFET using a commercial device simulator. We demonstrate that the proposed structure increases on–off current ratio by orders of magnitude and considerably improves self-heating effect in comparison with the conventional uniform doping fully depleted silicon-on-insulator MOSFET (C-SOI) which uses side gate for better electrical performance. 相似文献
A concise enantiodivergent total synthesis of (+)- and (−)-quercus lactones from the known tricyclic lactone (+)-1 as a single chiral template was achieved using the diastereoselective nucleophilic addition of organometallic reagents as the key step. 相似文献
In this work, the combination of the advantages of two-phase catalysis, electrocatalysis and colloid catalysis is presented. It is shown that palladium or gold colloids prepared by citrate reduction can be charged negatively in a heterogeneous two-phase reaction and subsequently used as aqueous catalysts for dehalogenation reactions. This can be regarded as a new type of electrocatalysis. 相似文献
