The effects of a sodium (Na) promoter on the catalytic performance cobalt-manganese (CoMn) catalysts for Fischer–Tropsch to olefin (FTO) reactions were investigated. For sample without Na, Co0 was found be active phase traditional Co-based reaction with low CO2 selectivity. olefin/paraffin (O/P) ratio C2–4= selectivity only 15.4 C%. However, addition cobalt carbide (Co2C) quadrangular nanoprisms (101) and (020) facets exposed formed. Co2C displayed high (54.2 C%) as well methane (5.9 under...
The Fischer–Tropsch to olefins (FTO) reaction over Co2C catalysts is structure-sensitive, as the catalytic performance strongly influenced by surface structure of active phase. exposed facets determine structure, and it remains a great challenge precisely control particle morphology FTO In this study, controlling effect Mn promoter on final nanoparticles for was investigated. unpromoted catalyst several promoted with Ce, La, Al were also studied comparison. For Mn-promoted catalysts,...
Person search aims at jointly solving Detection and Re-identification (re-ID). Existing works have designed end-to-end networks based on Faster R-CNN. However, due to the parallel structure of R-CNN, extracted features come from low-quality proposals generated by Region Proposal Network, rather than detected high-quality bounding boxes. is a fine-grained task such inferior will significantly reduce re-ID performance. To address this issue, we propose Sequential End-to-end Network (SeqNet)...
3D human shape and pose estimation is the essential task for motion analysis, which widely used in many applications. However, existing methods cannot simultaneously capture relations at multiple levels, including spatial-temporal level joint level. Therefore they fail to make accurate predictions some hard scenarios when there cluttered background, occlusion, or extreme pose. To this end, we propose Multi-level Attention Encoder-Decoder Network (MAED), a Spatial-Temporal Encoder (STE)...
Few-shot object detection (FSOD) aims to transfer knowledge from base classes novel classes, which receives widespread attention recently. The performance of current techniques is, however, limited by the poor classification ability and improper features in head. To circumvent this issue, we propose a Multi-level Feature Enhancement (MFE) model improve feature for three different perspectives, including spatial level, task level regularization level. First, revise classifier's input at using...
Abstract A series of Co/ SiO 2 catalysts with different sodium (Na) loadings (0, 0.1, 0.2, 0.5 and 1 wt%) were prepared evaluated for Fischer‐Tropsch reaction to study the effect Na on catalyst structure catalytic performance. The addition was found decrease activity hydrocarbon selectivity, but increase CO selectivity due enhanced WGS activity. also resulted in higher oxygenates (alcohols aldehydes) O/P ratio as well shift hydrocarbons lower carbon numbers. Structure characterization...
Alkali metal promoters are beneficial for the formation and facet-stabilization of Co<sub>2</sub>C nanoprisms FTO reaction.
To overcome the inconsecutive drawback of shadow and schlieren photography, complete dynamics cavitation bubble oscillation or ablation products induced by a single holmium laser pulse [2.12μm , 300μs (FWHM)] transmitted in different core diameter (200, 400, 600μm ) fibers is recorded means high-speed photography. Consecutive images from cameras can stand for true process laser-water laser-tissue interaction. Both energy fiber determine size, which further determines acoustic transient...
Cobalt carbide (Co2C) nanoprisms are efficient for olefin production via Fischer–Tropsch to (FTO) reaction. However, these Co2C can only be prepared from the given CoMn composite oxide precursor with a sodium promoter and formation mechanism remains ambiguous up now. In present work, Ce-stabilized spherical Co nanoparticles were synthesized used as study of active phase. The experimental results theoretical analysis showed that Ce promoters favorable provide oxygen dangling bonds surface...
It is demonstrated that an asymmetric Fabry-Pérot fiber-optic pressure sensor capable to precisely measure liquid levels. They are directly proportional pressures can modulate cavity length of cavity. As a result, the operate over linear region interference fringe enables liquid-levels interrogation by measuring reflected intensity. Experimental results show resolving power 0.4 mm, sensitivity 2.4 mV/mm, and precision 1 mm range 2.3 m (water) be achieved. The levels accurately, continuously,...
Low intensity irradiation of cells by laser was an effective method biostimulation. Here, we have extended these actions to evaluate the apoptosis effects in red light emitting diode (RLED) exposure. Through morphological observation, flow cytometric analysis, intracellular calcium measurement and RT-PCR, found that HeLa 24 h RLED in-vitro experiments would significantly affects induction cellular apoptosis, changes such as loose arrangement cells, noticeable development apoptotic bodies,...
Irradiation source has been a serious impediment to induce photocatalytic bacterial inactivation which was taken as an advanced indoor air purification technique. Here we reported the synergistic effects of 405 nm LED light and TiO 2 photocatalyst in process Staphylococcus aureus ( S. ). In this work, N-doped particles were, respectively, suspended into nutrient broth suspension with . Then, mixed system exposed energy density about 0.2 W/cm for 3 hours. Irradiated then scanned by UV-vis...
The major challenge in the production of xylene from benzene alkylation with methanol is to avoid side reaction olefins, and this leads low utilization efficiency generation byproduct ethylbenzene. Hierarchical porous Ti-ZSM-5 appropriate acidity was achieved by substituting part Al Ti synthesis process, which exhibited high suppression ethylbenzene formation efficient olefins.
