Wireless sensor networks(WSN)are widely used in many situations,but the disordered and random deployment mode will waste a lot of sensor resources.This paper proposes a multi-topology hierarchical collaborative particle swarm optimization(MHCHPSO)to optimize sensor deployment location and improve the coverage of WSN.MHCHPSO divides the population into three types topology:diversity topology for global exploration,fast convergence topology for local development,and collaboration topology for exploration and development.All topologies are optimized in parallel to overcome the precocious convergence of PSO.This paper compares with various heuristic algorithms at CEC 2013,CEC 2015,and CEC 2017.The experimental results show that MHCHPSO outperforms the comparison algorithms.In addition,MHCHPSO is applied to the WSN localization optimization,and the experimental results confirm the optimization ability of MHCHPSO in practical engineering problems.

The two-electron electrochemical reduction of oxygen is an appealing approach to produce hydrogen peroxide.Metal and heteroatom-doped carbon(M–X/C)materials have recently been recognized as compelling catalysts for this process,but their performance improvement is generally hindered by the ill-defined structures of active sites.Herein,we demonstrate a theory-driven design of catalysts for oxygen reduction reactions based on molecularly dispersed electrocatalysts(MDEs)with metal phthalocyanines on carbon nanotubes.Density functional theory calculations suggest that nickel phthalocyanine(NiPc)favors the formation of*H_(2)O_(2) over*O,thus acting as a selective catalyst for peroxide production.NiPc MDE shows high peroxide yields of∼83%,superior to the aggregated NiPc and pyrolyzed Ni–N/C catalysts.The performance is further enhanced by the introduction of the cyano group(CN).NiPc–CN MDE exhibits∼92%peroxide yields and good stability.Our studies provide a new perspective for the development of heterogeneous electrocatalysts for hydrogen peroxide production from metal macrocyclic complexes.

As future energy-saving optoelectronics,bistable electrochromic(EC)materials/devices have high energy efficiency for potential applications as smart windows,displays,and information/energy storage,due to their ability tomaintain optical states without consuming energy.However,further development is hindered by the lack of in-depth understanding of related key factors and universally applicable design strategies to achieve bistability.

Metal phthalocyanines(MePcs)have been considered as promising catalysts for CO2 reduction electrocatalysis due to high turnover frequency and structural tunability.However,their performance is often limited by low current density and the performance of some systems is con troversial.Here,we report a carb on nano tube(CNT)hybridizati on approach to study the electrocatalytic performa nee of MePcs(Me=Co,Fe and Mn).MePc molecules are anchored on CNTs to form the hybrid materials without noticeable molecular aggregations.The MePc/CNT hybrids show higher activities and better stabilities than their molecular counterparts.FePc/CNT is slightly less active than CoPc/CNT,but it could deliver higher Faradaic efficiencies for CO production at low overpotentials.In contrast,the catalytic performance of MePc molecules directly loaded on substrate is hin dered by molecular aggregati on,especially for FePc and MnPc.Our results suggest that carbon nano tube hybridization is an efficient approach to construct advaneed MePc electrocatalysts and to understand their catalytic performance.

The solubility of H_(2)S was measured in solutions of N-butyl-N-methylmorpholine acetate([Bmmorp][Ac])containing 20%-40%(mass)water at experimental temperatures ranged from 298.15 to 328.15 K and pressures up to 320 k Pa.The total solubility of H_(2)S increased with higher temperatures,lower pressures,and reduced water content.The reaction equilibrium thermodynamic model was used to correlate the solubility data.The results indicate that the chemical reaction equilibrium constant decrease with increasing water content and temperature,whereas Henry constant increase with increasing water content and temperature.Compared with other ionic liquids,H_(2)S exhibits a higher physical absorption enthalpy and a lower chemical absorption enthalpy in[Bmmorp][Ac]aqueous solution.This suggests that[Bmmorp][Ac]has a strong physical affinity for H_(2)S and low energy requirement for desorption.Quantum chemical methods were used to investigate the molecular mechanism of H_(2)S absorption in ionic liquids.The interaction energy analysis revealed that the binding of H_(2)S with the ionic liquid in a1:2 ratio is more stable.Detailed analyses by the methods of the interaction region indicator and the atoms in molecules were conducted to the interactions between H_(2)S and the ionic liquid.

Although various anti-osteoporosis drugs are available,the limitations of these therapies,including drug resistance and collateral responses,require the development of novel anti-osteoporosis agents.Rhizoma Drynariae displays a promising anti-osteoporosis effect,while the effective component and mechanism remain unclear.Here,we revealed the therapeutic potential of Rhizoma Drynariae-derived nanovesicles(RDNVs)for postmenopausal osteoporosis and demonstrated that RDNVs potentiated osteogenic differentiation of human bone marrow mesenchymal stem cells(hBMSCs)by targeting estrogen receptor-alpha(ERα).RDNVs,a natural product isolated from fresh Rhizoma Drynariae root juice by differential ultracentrifugation,exhibited potent bone tissue-targeting activity and anti-osteoporosis efficacy in an ovariectomized mouse model.RDNVs,effectively internalized by hBMSCs,enhanced proliferation and ERαexpression levels of hBMSC,and promoted osteogenic differentiation and bone formation.Mechanistically,via the ERαsignaling pathway,RDNVs facilitated mRNA and protein expression of bone morphogenetic protein 2 and runt-related transcription factor 2 in hBMSCs,which are involved in regulating osteogenic differentiation.Further analysis revealed that naringin,existing in RDNVs,was the active component targeting ERαin the osteogenic effect.Taken together,our study identified that naringin in RDNVs displays exciting bone tissue-targeting activity to reverse osteoporosis by promoting hBMSCs proliferation and osteogenic differentiation through estrogen-like effects.
