This paper demonstrates a one-pot approach to produce highly dispersed dendritic palladium-platinum bi- metallic nanoparticles （NPs） with small particle size, tunable composition and high catalytic activity. Herein, the PdPt bi- metallic NPs have been obtained using bayberry tannin （BT） as both the reducing agent and surfactant. Additionally, the PdPt bimetallic NPs with different Pd/Pt atomic ratios can be prepared by just varying the amounts of the Pd and Pt pre- cursors. Most importantly, the as-prepared Pd52Pt4s catalyst exhibits the optimal catalytic activities compared with the other compositional PdPt NPs （Pds2Ptls, Pd69Ph~, and Pd36 Pt64） and commercial Pt/C （20 wt.%） catalyst for the methanol oxidation reaction （MOR）. Meanwhile, Pd52Pt4s also shows better CO tolerance, which can be attributed to the unique dendritic structure and the synergistic effect between Pd and Pt. With evident advantages of the facile preparation and enhanced catalytic performance, it holds great promise as a high-performance catalyst for electrochemical energy con- version.

Background and Aims:A functional cure,or hepatitis B virus(HBV)surface antigen(HBsAg)loss,is difficult to achieve in patients with hepatitis B virus e antigen(HBeAg)-positive chronic hepatitis *** HBV vaccine and granulocyte-macrophage colony-stimulating factor(GM-CSF)have been reported to help reduce HBsAg levels and promote HBsAg *** this prospective randomized trial,we evaluated HBsAg loss in patients receiving pegylated interferon α2b(PEGIFN-α2b)and tenofovir disoproxil fumarate(TDF),with and without GM-CSF and HBV ***:A total of 287 patients with HBeAg positive chronic hepati-tis B and seroconversion after nucleot(s)ide analog treat-ment were assigned randomly to three treatment groups for 48 weeks,TDF alone(control),PEGIFN-α2b+TDF,and PEGIFN-α2b+TDF+GM-CSF+HBV *** prima-ry endpoints were the proportions of patients with HBsAg loss and seroconversion at 48 and 72 ***/ts:The cumulative HBsAg loss rates in the control,PEGIFN-α2b+TDF,and PEGIFN-α2b+TDF+GM-CSF+HBV vaccine groups at week 48 were 0.0%,28.3%,and 41.1%,*** cumulative HBsAg seroconversion rates in these groups at week 48 were 0.0%,21.7%,and 33.9%,*** regression analysis showed that GM-CSF use plus HBV vaccination was significantly associated with HBsAg loss(p=0.017)and seroconversion(p=0.030).Con-clusions:In patients with HBeAg-positive chronic hepatitis B and seroconversion after nucleot(s)ide analog treatment,immunomodulatory/antiviral treatment regimens effective-ly improved HBsAg loss,and the regimen including GM-CSF and HBV vaccination was most effective.

Using minimal photothermal material to achieve maximum evaporation rate is extremely important for practical applications of interfacial solar evaporation *** this work,we found that with the increase in the size of evaporation surfaces,the evaporation rate *** experimental and numerical simulation results confirmed that when the evaporation surface size increased,the middle portion of the evaporation surface acted as a‘‘dead evaporation zone”with little contribution to water *** on this,the middle portion of the evaporation surface was selectively removed,and counterintuitively,both the evaporation rate and vapor output were increased due to the reconfigured and enhanced convection above the entire evaporation *** such,this work developed an important strategy to achieve a higher evaporation rate and increased vapour output while using less material.

The Pt-based catalyst tends to be poisoned by carbon monoxide(CO)-like intermediates produced in fuel cell reactions,which seriously deteriorates its catalytic ***,noble metal Au with the capacity of resistance to CO-like intermediates poisoning was employed to construct multi-element Pt-based *** trimetallic NiPtAu hollow nanocrystals(HNCs)with different surface Au contents were synthesized to explore the role of Au in electrocatalysis for alkaline methanol oxidation reaction(MOR).The trimetallic NiPtAu-SRAu HNCs catalyst with the relative rich Au content(15.17 at%)on surface exhibits a much lower CO oxidation peak potential than the other HNCs counterpart and 20 wt%Pt/C,which indicates the more exceptional CO-resisting ***,the MOR specific activity of NiPtAu-SRAu HNCs(31.52 mA cm^−2)is 7 times higher than that of 20wt%Pt/C(4.50 mA cm^−2).This enhancement in catalytic activity as well as anti-CO poisoning capability for NiPtAu-SRAu HNCs can be mainly ascribed to the weakened CO adsorption due to the exposure of Au atoms on NiPt surface evidenced by the experimental data and density functional theory *** study not only investigates the role of Au in MOR catalysis but also could be helpful for designing and optimizing the electrocatalysts for high-active and robust fuel cell applications.
