TL;DR: In this article, a vertical up-flow constructed wetlands with manganese ore (Mn ore) as media (M-CWs) were developed to treat simulated polluted river water, and the results showed that the average removal efficiencies for NH4-N, NO3N, TN and TP were 91.74, 83.29, 87.47, and 65.12% in M-CW, respectively, which were only 79.12, 72.90, 75.85% and 43.23% in the CWs without Mn ore (C-

TL;DR: The robust stability and stabilization of Boolean networks with stochastic function perturbations is studied and it is proved that the finite-time stability is reduced to stability in distribution when the intersection of perturbed set and complement set of parameterized set is nonempty.
Abstract: In genetic regulatory networks (GRNs), gene mutations often occur in a stochastic manner. As an important model of GRNs, gene mutations of Boolean networks are always described as function perturbations. This article studies the robust stability and stabilization of Boolean networks with stochastic function perturbations. A kind of parameterized set is constructed, and it is revealed that under the stochastic function perturbations, the property of finite-time stability remains unchanged when the perturbed set and the parameterized set are disjoint. In addition, it is proved that the finite-time stability is reduced to stability in distribution when the intersection of perturbed set and complement set of parameterized set is nonempty. As an application, the robust stabilization problem of Boolean control networks with stochastic function perturbations is discussed, and several necessary and sufficient conditions are presented for the robustness of feedback stabilizers. Finally, the obtained results are used to study the Drosophila melanogaster segmentation polarity gene network and the lac operon in the bacterium Escherichia coil.

TL;DR: Density functional theory calculations have been performed to investigate the detailed mechanism of the carbonyl hydrogenation catalyzed by the first well-defined bifunctional iron catalyst.
Abstract: Density functional theory calculations have been performed to investigate the detailed mechanism of the carbonyl hydrogenation catalyzed by the first well-defined bifunctional iron catalyst. The catalytic reaction proceeds by hydrogen transfer and dihydrogen activation. The hydrogen transfer reaction occurs via the bifunctional mechanism in which the two hydrogen atoms attached on the Fe and O of the catalyst are transferred to the oxygen and carbon atom of the carbonyl compound concertedly. Both the alcohol-mediated and nonalcohol-mediated dihydrogen activation processes are explored.

TL;DR: In this article, two types of bio-wastes, Platanus fruit and willow catkins, were used to prepare hollow carbon micro-fibers, where their size and microstructure are dependent on the Platanus fibre fibers andwillow catkin fibers.
Abstract: Normally, structural details of the tissue of bio-waste affect the final properties of carbon materials. In this study, we selected two types of bio-wastes, Platanus fruit and willow catkins, to prepare hollow carbon micro-fibers, where their size and microstructure are dependent on the Platanus fruit fibers and willow catkin fibers. The electrode properties of the Platanus-derived hollow micro carbon fibers are much higher than those of the willow-derived micro carbon fibers, although carbonization and activation processes are the same for the two types of materials. It is found that the content of the organic-related elements, C, N, and S, and the content of inorganic ions, K or Na, are different. The high content of N and S induced a high doping concentration of the hollow carbon micro-fibers, which endows the Platanus-derived carbon materials with high conductivity, and the high content of inorganic elements causes a self-activation effect during the carbonization process and results in a special porous microstructure of the Platanus-derived carbon. Therefore, compared with the willow-derived hollow carbon micro-fibers, after carbonization and KOH activation, the hollow carbon micro-fibers derived from Platanus seeds possessed much higher supercapacitor electrode properties. After carbonization and activation under optimized conditions, the specific capacitance of the Platanus- and willow-derived hollow carbon micro-fibers are 304.65 F g−1 and 276.13 F g−1, respectively, at the current density of 0.5 A g−1, with a good rate capability and 88.5% and 81.05% capacity retention at 10 A g−1, respectively. The coin-type symmetric device of these two samples with 6 M KOH electrolyte exhibited a high specific capacitance of 286.5 and 267.5 F g−1, respectively, at 0.25 A g−1 (PFs 900, WFs 800), with an excellent cycling stability and 97.03% and 91.12% capacity retention after 10000 cycles, respectively. This work not only provided two types of promising supercapacitor carbon materials but also, most importantly, offered us clues for the design and synthesis of high-performance electrode materials using the knowledge gleaned from nature.
