Sheaf-like and layered CeO2 with micro/nanocomposite structure were synthesized by a simple friendly hydrothermal method used in lean methane combustion. The relationship between the catalytic performance combustion has been studied means of XRD, SEM, TEM&HRTEM, H2-TPR, BET XPS. According to H2-TPR results, reducibility sheaf-like is higher compared CeO2. XPS results reveal that oxygen vacancies are more easily formed on surface than surface. activity strongly related its morphology;...
The difference of NH3 oxidation mechanism over SAPO-34 and Cu-SAPO-34 was studied. XRD (X-ray diffraction), SEM (scanning electron microscopy) H2-TPR (H2-temperature programmed desorption) were conducted to estimate the Cu species distribution. quantity individual Cu2+ ions escalated with elevation silicon content in Cu/SAPO-34 catalysts, leading an enhancement activity NH3-SCR (ammonia-selective catalytic reduction) process. This augmentation can be attributed increased presence isolated...
In present work, the catalytic performance of Cu-SAPO-34 catalysts with or without propylene during NH3-SCR process was conducted, and it found that de-NOx activity decreased low temperature ranges (<350 °C), but obviously improved within range high temperatures (>350 °C) in presence propylene. The XRD, BET, TG, NH3-TPD, NOx-TPD, situ DRIFTS gas-switch experiments were performed to explore effect on structure catalysts. bulk characterization TG results revealed neither coke deposition...
The mechanical properties of an Mg–Zn–Ca alloy were significantly improved through extrusion deformation. High-density spheroidal Ca 2 Mg 6 Zn 3 with a diameter ranging from 10 to 50 nm dynamically precipitated during microstructure the as-extruded was obviously refined compared that as-cast counterpart. A bimodal consisting coarsely deformed grains and finely recrystallised obtained extrusion. Additionally, exhibited strong basal texture. Consequently, yield strength increased 42 MPa 285 alloy.
Abstract The tribe‐material is the key factor affecting performance of triboelectric nanogenerators (TENGs). Inorganic materials have higher heat resistance and stability than widely used organic materials. However, weaker tribe‐property limits application TENGs. Modulating surface roughness by changing particle shape size a simple way to increase for Polyoxometalates (POMs) unrivalled structural diversity can self‐assemble form different nanostructures. In this study, we propose [{(NH 4 )...
The interfacial Dzyaloshinskii–Moriya interaction (DMI) acting as an essential source to stabilize spin textures in ferromagnetic ultrathin films has revealed its significant role spin–orbit torque (SOT)-driven magnetic switching. Based on a convincing homochiral Néel domain wall model, the in-plane (IP) field associated with DMI effect been confirmed prerequisite for deterministic SOT-driven Although presence of IP is required, impact magnitude combined switching different heavy metals...
Abstract In the process of evaluating quality a batch 125S casing for oil and gas wells, it was found that mechanical properties different bodies in same were significantly different, fluctuation range yield strength up to 60 MPa. The steel pipe with lowest not satisfied according technical standards. order study causes uneven tensile properties, chemical composition analysis, tests, Charpy impact Rockwell hardness tests metallographic analysis investigated two casings this batch. Through...
Holography always records the 3D object information via interference and then reconstructs diffraction. A holographic optical element (HOE) can be fabricated by analog exposure or digital printing. Since HOE recorded on a thin plate film of material, it is utilized as combiner for augmented reality near-eye displays to achieve compact form factor. The traditional method fabrication divide coherent light beam into both signal reference beam, make beams meet at material interference. path...
