COVID-19 has created a new lifestyle in many social and economic activities, which leads to influencing the e-commerce market. A new type of e-commerce called “Live Commerce” has emerged in the form of a combination of streaming video and e-commerce. Despite the growth potential and the importance of live commerce, prior studies have been conducted by considering only some part of it: platforms, sellers, and consumers. Therefore, this study aims to empirically investigate influencing factors of intention to watch and purchase in a live commerce platform. The research model was developed based on the consideration of unique factors of live commerce and the Stimulus-Organism-Response (S-O-R) framework. This study found major influencing factors of intention to watch and purchase from the result of structural equation model (SEM) testing with 298 responses from users of Taobao Live. The findings of this study could help formulate strategies and provide practical insights for live commerce platforms to increase sales by presenting influencing factors influencing watching and purchase intentions.
Sensorless Control of the Switched Reluctance Motor Based on the Sliding-Mode Observer

To upgrade the application of switched reluctance motors (SRMs) for more electric aircraft, this paper presents a method with sensorless control based on the flux-linkage data from the finite element method. First, a calibration strategy is employed to obtain the flux-linkage characteristics. Then, a sliding-mode observer is used to realize the sensorless control of the SRM. The proposed method only requires the flux-linkage of the SRM at aligned and unaligned rotor positions from the experiment which takes a low-measurement effort to get the rotor position and has better accuracy in position and speed estimation than the FEM. Experimental results verify the accuracy and effectiveness of the proposed method.

Adsorbed benzene/toluene on Ag-MnOx/g-Al2O3 and Ag-MnOx-CoOx/g-Al2O3 catalysts can be oxidisedby non-thermal plasma with gas circulation. The results showed that the gas circulation systemeffectively avoided the emissions of VOCs caused by plasma desorption. After the gas was circulated for90 min, compared to g-Al2O3, the introduction of Ag-MnOx/g-Al2O3 improved the COx yield by 33%, withCO2 selectivity close to 100%, and reduced the amount of O3 by 51%, while Ag-MnOx-CoOx/g-Al2O3inhibited N2O formation by 38% in comparison with g-Al2O3. Furthermore, the elimination mechanismsof N2O, O3, and the byproducts on the surface of catalysts were studied.

The removal of toluene using a cycling adsorption and plasma mineralization process was investigated ina packed reactor. The supports of catalysts were optimized in regards to mineralization rate (MR), CO2selectivity (SCO2), and the production of by-products. The hybrid support g-Al2O3-HY showed a muchbetter MR in comparison to that of HY alone. Using hybrid HY-g-Al2O3 as supports, loading Ag–Mn ononly HY or g-Al2O3 had a better MR than loading Ag–Mn on both HY and g-Al2O3. The stability studyshowed that intermediates accumulated on the surface of the catalyst lead to its deterioration.

A non-thermal plasma with a wet scrubber (NTP + WS) was used to degrade gaseous toluene. Comparedwith the NTP + WS/H2O system, the toluene and by-product ozone removal efficiencies were increased by10% and 85% in the NTP + WS/Fe2+ system, respectively. For 60 ppm toluene degradation, the maximummineralization rate (MR) of toluene (61%) was obtained, at the optimum Fe2+ concentration of 50 mg/L. During catalytic oxidation, the removal efficiency of toluene was limited by its solubility in WS systems. In addition, decreased Fe2+ concentration and accumulation of organics led to the system deactivation. The EPR and quenching experiments verified the presence and contribution of hydroxyl radicals (4.6%)and superoxide radicals (3.8%) to the removal efficiency of toluene. Based on the radicals and intermediatesdetected in the gas and liquid phases, a degradation mechanism for toluene in the NTP + WS/Fe2+system was proposed.

Two-component zeolite-alumina packed dielectric barrier discharge plasma was developed to deeplymineralize toluene. Compared with packing ZSM-5 and g-Al2O3 separately in layers, uniform mixing ofZSM-5 and g-Al2O3 was more conducive to the mineralization of adsorbed toluene in nonthermal plasma. When the mixing ratio of ZSM-5 to g-Al2O3 was 1:2, the mineralization rate reached 80% afterdischarging for 120 min. Ag supported on the catalyst surface significantly improved the selectivity ofCO2. Increased relative humidity had little effect on the mineralization of adsorbed toluene, butsignificantly reduced the byproducts O3 and N2O. The adsorption and plasma mineralizationperformance of Ag/ZSM-5-g-Al2O3 duringfive cycles of toluene adsorption was stable with only thepeak concentration of CO showing a slight upward trend. GC–MS, TG, and XPS characterization of freshand used catalysts revealed deactivation of Ag/ZSM-5-g-Al2O3 in terms of CO oxidation due tointermediate organic residues and decreased amounts of Ag+ and lattice oxygen on the support ZSM-5instead of g-Al2O3.

Toluene abatement through adsorption and then plasma oxidation using ZSM-5, ZSM-5-γ-Al2O3 (Z-Al), ZSM-5-TiO2 (Z-Ti), ZSM-5-BaTiO3 (Z-Ba), and AgMn/ZSM-5-BaTiO3 (AgMn/Z-Ba) as adsorbents/catalysts was investigated. The efficiency of toluene removal reached ∼100% for all the tested adsorbents/catalysts. ZSM-5 had the lowest mineralization rate (MR) of ∼43%, while Z-Ba had the highest MR (88%) with an SCO2 of ∼80%. After loading AgMn onto Z-Ba, both the breakthrough capacity of toluene and SCO2 was increased, while the production of byproduct O3 and MR was decreased. The mixed materials created a higher amount of active species capable of deeply oxidizing adsorbed toluene.

Citric acid chemical extraction technology in combination with ultrasonication was used to removeheavy metals from industrial and municipal mixed sludge. The removal efficiencies of Zn, Ni, Cr and Cureached 53.5%, 40.2%, 35.4% and 13.1%, respectively, at citric acid concentration of 0.2 M assisted byultrasound for 20 min. The extracted Zn, Ni and Cr mainly came from acid-soluble, reducible andoxidizable fractions, and Cu mainly came from oxidizable and reducible fractions. The presence of Fe3+,Al3+ and Ca2+ improved the extraction efficiency of Cu from the sludge significantly. The extracted sludgecould be used for soil amendment.
