The intense coupling by gradient doping offers an effective approach to enable the plasmon resonances of Ti excited by visible light. The Ti-based plasmonic heterostructure potentially opens an alternative avenue towards sustainable plasmon-enhanced catalysis.Structural, magnetic and theoretical studies of three octahedral mononuclear DyIII complexes with triphenylphosphine oxide and halide ligands are reported. The Cl- and Br- analogues exhibit SMM behavior with energy barriers of 49.1 K and 70.9 K, respectively under a small dc field. Ab initio calculations were performed, the results of which predict higher energy barriers for iodide containing SMMs.MAPb(I1-xBrx)3 is widely used as a window layer in tandem solar cells. Ion migration is one of the most important factors that results in phase separation in MAPb(I1-xBrx)3 and eventually causes a decrease of cell performance. Recent research demonstrates that the doping of Cs+ and the formation of low-dimensional perovskite structures are effective means of inhibiting the migration. To investigate the causes of the migration and its inhibition mechanisms in hybrid halide perovskite materials, large-scale quantum dynamics simulations are conducted on MAPbI3, MAPb(I0.4Br0.6)3 and Cs0.125MA0.875Pb(I0.4Br0.6)3, respectively. By tracking changes in the geometric structures of the perovskite materials before and after doping with Br- and Cs+ in the dynamics processes, the precondition for the ion migration is firstly revealed. The dimension reduction of the perovskite skeleton structures by introducing Cs+ is observed. Furthermore, by combining observations with the variations of the band gap values in all the systems, the inhibition mechanisms of Cs+ doping on ion migration in MAPb(I1-xBrx)3 are revealed.Correction for 'Nanoporous two-dimensional MoS2 membranes for fast saline solution purification' by Jianlong Kou et al., Phys. Chem. Chem. Phys., 2016, 18, 22210-22216.An efficient copper-catalyzed tandem regioselective cis-carbometallation/cyclization of imine-ynamides with arylboronic acids has been developed. https://www.selleckchem.com/products/bgb-8035.html This method leads to a facile and practical synthesis of valuable 2,3-disubstituted indolines in moderate to excellent yields and features a broad substrate scope and wide functional group tolerance. Other significant features of this protocol include the use of readily available starting materials, high flexibility, simple procedure and mild reaction conditions.Inspired by the structural features of native peroxidases, an artificial peroxidase was rationally designed using F43Y myoglobin with a Tyr-heme cross-link by further introduction of key residues, including both a distal Arg and a Trp close to the heme group, which exhibits an enhanced peroxidase activity similar to the most efficient native horseradish peroxidase. This study provides a simple approach for design of artificial heme enzymes by the combination of catalytic elements of native enzymes with the post-translational modifications of heme proteins.Ni(OH)2 has been widely investigated as a prospective electrode material because of its high theoretical capacitance and relatively low cost. However its synthesis usually needs a complex and lengthy process, and a binder is generally used for fabricating Ni(OH)2 based electrodes. In this work, a self-supporting binder-free β-Ni(OH)2@nickel foam (NF) integrated electrode was prepared by the in situ growth of β-Ni(OH)2 on NF using a rapid and facile approach. This approach consists of two processing steps (1) the pre-treatment of NF with an acid and (2) the quick in situ electrochemical synthesis of β-Ni(OH)2 on the NF in the KOH electrolyte within half a minute under an applied voltage. The β-Ni(OH)2@NF integrated electrode possesses a three-dimensional network structure of nanosheet arrays and exhibits excellent electrochemical performance. Its areal capacity is 3.68 mA h cm-2 at a current density of 2 mA cm-2, and the capacity can retain 115.8% of its initial value even after 2000 cycles at a current density of 15 mA cm-2. Moreover, the as-assembled β-Ni(OH)2@NF//activated carbon (AC) asymmetric supercapacitor (ASC) exhibits a high energy density of 74.2 W h kg-1 with a power density of 776.9 W kg-1 and excellent cycling stability (89.9% retained after 10 000 cycles). This work provides an efficient, facile and economic method for fabricating Ni(OH)2 based integrated electrodes for high-performance supercapacitors.A high-efficiency top-down approach was used to fabricate orthorhombic MoO3-x nanocrystals through the synergic effect of oleic acid (OA) and oleylamine (OAm), in which OA provided H+ ions and OAm contributed free electrons. This investigation might provide new guidance for manipulating the optical properties of metal oxide semiconductors.Herein, 2D siloxene terminated by surface functional groups of Si-H and Si-OH is demonstrated to be an effective support for the spontaneous deposition of iridium nanoparticles (Ir NPs) to promote HER electrocatalysis. With ultra-low Ir loading, the obtained Ir NPs/siloxene electrocatalyst shows superior electrocatalytic activity toward the HER.The intimate crosstalk between endothelial and bony cells is essential for the reconstruction of bone tissue defects. Indeed, a successful bone repair is greatly dependent on the formation of new blood vessels, to ensure the supply of nutrients and gases, as well as the removal of metabolites. Bone morphogenetic proteins (BMPs) and vascular endothelial growth factor (VEGF) are involved on cells differentiation and bone vascularization aiming to develop viable bone tissue. Herein it is hypothesized that endogenous BMP-2 and VEGF bound in a parallel arrangement over a single nanofibrous substrate (NFM) can lead to a successful osteogenic and angiogenic differentiation of mesenchymal stem cells. For that, an engineered biofunctional system was developed comprising anti-BMP-2 and anti-VEGF antibodies, immobilized over an electrospun NFMs in a parallel pattern design, with the attempt to recreate the vasculature of bone tissue. The osteogenic and angiogenic potential of this engineered biofunctional system was demonstrated by culturing human bone marrow-derived mesenchymal stem cells (hBM-MSCs) during 21 days without exogenous induction.
