A series of Fe-based catalysts with accurately controlled amounts Na are synthesized to investigate the relationship between promoter and catalytic performance for CO2 hydrogenation alkenes. With increasing amount Na, both conversion alkenes selectivity increase at low moderate then plateau (with highest be 36.8% 64.3%, respectively), while corresponding methane production decreases 7.2%. It is found that addition enhances adsorption CO2, facilitates formation stability active species Fe5C2,...
Abstract The micro-texture, grain size, morphology, size and distribution of the second phase in 6063 Al alloys significantly influence comprehensive mechanical properties alloys. By adding Sr to alloys, this study performed a comparison effect exerted by micro-texture refinement explored existence its on phase. Inaddition, mechanism for Sr-added was also investigated. results show that structure is changed after 2 Si intermetallic compound formed, numerous substructures are developed during...
A study of the structure-property relationship highly π-conjugated Schiff-base moiety in polymerization a liquid crystal (LC) diepoxide oligomer (PBMBA) and mesophases stabilization has been investigated. We first proposed two exothermic peaks distinctly observed nonisothermal curves for thermal copolymerization PBMBA monomer with diamine comonomer that corresponded to different reactions, namely, an epoxy-amine anionic polymerization. For PBMBA, note unexpected homopolymerization...
In this paper, an interface circuit based on parallel-synchronous switch harvesting inductor (SSHI) is proposed for piezoelectric and thermoelectric energy harvesting. The could harvest power from transducers (PZT) generators (TEG) simultaneously with a single-shared inductor. addition, the harvester enables cold start without external battery. Simulation results indicate that has higher extraction capability by increasing damping force of PZT, overall output 15.8% than conventional SSHI...
Abstract The effect of Sr on the microstructure Al–4.6Mg alloy is studied via optical microscopy, scanning electron microscopy‐energy‐dispersive analysis, backscattered diffraction, transmission and intergranular corrosion susceptibility evaluated according to ASTM G67. main precipitation phases are β‐Al 3 Mg 2 Al 6 Mn, with a new square phase Mn also being formed. After addition Sr, decreases, morphology changes, 4 τ‐Al 38 58 Accordingly, nanoscale uniformly distributed inside grains....
The as-cast Al-4.6Mg alloy was subjected to deformation and sensitization-desensitization heat treatment, then the microstructure enhancement mechanism of Sr were investigated by optical microscopy, scanning electron microscopy-energy-dispersive spectroscopy, backscatter diffraction, transmission microscopy. precipitation phases mainly β-Al3Mg2, Al6Mn, Al6(Mn Cr), nanoscale Al3Mn Al11Mn4. formation β-Al3Mg2 hindered addition 0.1 wt.% Sr. In addition, precipitate phase Al4Sr nano-sized...
