The selective hydrogenation of cinnamaldehyde was investigated with Pt nanoparticles deposited on reduced graphene oxide (Pt/RGO). Compared carbon nanotubes (CNTs) or activated (AC) as support, Pt/RGO showed the best activity and selectivity for CO bond.
A facile strategy was developed for the preparation of Ru nanoparticles supported on reduced graphene oxide (Ru/rGO) and its following functionalization with benzenesulfonic acid groups (Ru/rGO-S). The formation a C–C bond between p-sulfophenyl sp2 carbon can be unambiguously confirmed by XPS quantitative analysis. two catalysts were used to catalyze conversion levulinic in aqueous phase, which is an important reaction during biorefinery. Not GC but HPLC found reliable analysis method this...
Abstract In this work, the influence of dry air on electron density ( n e ) and temperature T in a cascaded arc Ar plasma is firstly studied by state-of-the-art laser Thomson scattering approach. The results reveal that small amount can induce sharp drop , which ascribed dissociative recombination reactions between molecular ions formed charge transfer reactions. With increase ratio, exhibits non-monotonic trend initially increases then decreases. This should be caused cooperation...
China An effective evapotranspiration stress assessment system requires reliable estimates actual (ETa), and potential (ETp), should consider multiple influencing indicators. This study explores the consistency of evaporation reanalysis datasets across mainland fuses them with multi-model ensemble method. To address uncertainty inherent in traditional index (ESI) that only considers ETa ETp relationship, we employ Pearson Correlation Analysis a Random Forest-based Boruta Algorithm to propose...
Photocatalytic oxidation of organic compounds was carried out in water using a molecular catalyst and semiconductor photosensitizer.
As advanced linear plasma sources, cascaded arc devices have been used to generate steady with high electron density, particle flux and low temperature. To measure density temperature of the device accurately, a laser Thomson scattering (LTS) system, which is generally recognized as most precise diagnostic method, has established in our lab Dalian University Technology. The measured successfully region 4.5 × 1019 m−3 7.1 1020 0.18 eV 0.58 eV. For comparison, an optical emission spectroscopy...
The electron density and temperature of the recombining argon plasma from a cascaded arc discharge source were measured by laser Thomson scattering approach. In this paper, small amount nitrogen gas was introduced into source. addition applied to investigate change parameters in terms temperature. measurements showed that dropped 2 orders magnitude at 10% compared with no addition. dissociative recombination following charge transfer between atomic ions molecules responsible for decrease...
In this paper, an efficient coupled lattice Boltzmann–large eddy simulation model [X. An et al., “Coupled Boltzmann-large for three-dimensional multiphase flows at large density ratio and high Reynolds number,” Phys. Rev. E 104, 045305 (2021)] based on the Allen–Cahn phase-field theory is introduced simulating liquid breakup in planar prefilming airblast atomization. This first time that Boltzmann method used numerical investigation of atomization to best our knowledge. The present utilizes...
Abstract Cascaded arc plasma has been widely applied in linear devices (LPDs) to produce high flux for the study of plasma-material interaction. In this work, cascaded He produced an LPD with a compact arrangement is investigated by voltammetry and optical emission spectroscopy (OES). The results show that cathode potential increases discharge current while it firstly decreases then as increasing gas flow rate. A local reverse electric field observed at low rates between two plates (i.e....
Abstract In this study, the electron density ( n e ) and temperature T in an unmagnetized cascaded arc helium (He) plasma are precisely determined using cutting-edge laser Thomson scattering. our experimental scope, is only 10 18 m −3 less than 0.2 eV, both of which substantially lower linear devices (LPDs). The comparison values He with those Ar reveals that these two parameters likewise significantly they on average. to gas, degree ionization low due its high potential, diffusive loss...
A strain of Myrmecridium was isolated from farmland soil in Guizhou Province, China. The produced distinctive obovoid or fusoid conidia that taper to a subtruncate darkened hilum at the base distinguished it other species. Phylogenetic analysis combined ITS1–5.8S–ITS2 and large subunit rDNA sequences supported this morphological separation. We describe obovoideum as new provide key
Lithiation is beneficial to enhance plasma performance in EAST by reducing hydrogen and impurities recycling via lithium (Li) wall conditioning. High-Z materials like tungsten (W) have been selected as up–divertor tokamak. However, the nature of chemical compositions states on Li-W co-deposition layer still unclear. In this paper, pure W plasma-facing component experiments with Li deposition were carried out a cascaded-arc linear generator. An in-situ laser-induced breakdown spectroscopy...

Abstract A systematic investigation of the plasma response to an externally applied resonant magnetic perturbation (RMP) field, for purpose controlling edge localized modes, is carried out EU DEMO reference plasma. Particular emphasis placed on role kinetic effects associated with both thermal particles and fusion-born alphas. The single fluid, resistive model predicts a large peak amplification n = 1 ( toroidal mode number) target equilibrium, which found be close Troyon no-wall limit. more...
Laser-induced breakdown spectroscopy (LIBS) has been developed to in situ diagnose the chemical compositions of first wall EAST tokamak. However, dynamics optical emission key plasma-facing materials, such as tungsten, molybdenum and graphite have not investigated a laser produced plasma (LPP) under vacuum.
