As big data and the Internet continue to advance, there is much space for new retail models to emerge. Luckin Coffee, one of the top brands in China’s coffee industry, has seen significant growth in both market share and brand recognition thanks in large part to its marketing approach. This study gathers a great deal of official data to understand the reasons behind Luckin Coffee’s rapid popularity in China. It then applies SWOT analysis to evaluate Luckin Coffee’s marketing approach. Luckin Coffee initially succeeded due to its rapid expansion and technological innovation but faced setbacks due to financial mishandling and excessive reliance on discounts. Fortunately, the company was rescued promptly and focused on developing its products. However, competition in the Chinese beverage industry is very fierce. The authors offer several recommendations for tweaks to the current marketing mix in the conclusion to aid Luckin Coffee in enhancing its core competency. It also knows the demand and market for coffee in China in recent years. To expand the product brand and produce more best-selling items, Luckin Coffee ought to use brand co-branding. Similarly, it is necessary for Luckin Coffee to developLuckin Coffee must develop localized products and establish its ecosystem. The suggestions might also serve as a source of inspiration for creating and growing a mid-range Chinese coffee company.

Integration of more thermodynamically favorable valorization of biomass (e.g., glycerol), compared to sluggish oxygen evolution, with H2 production is of great significance for energy‐saving electrosynthesis of value‐added chemicals. However, its widespread deployment has been challenged by costly electrocatalysts and large overpotential reaching an industrial‐relevant current density (≥400 mA cm−2). Herein, carbon shell‐encapsulated manganese‐doped cobalt nitride nanoarrays immobilizing on nickel foam, denoted Mn‐CoN@C/NF, are crafted via hydrothermal method and ammoniation. As a bifunctional electrocatalyst, the Mn‐CoN@C/NF manifests extraordinary activity for glycerol oxidation reaction (GOR) with an ultralow potential of 1.37 V (versus RHE) at 400 mA cm−2, in conjunction with H2 evolution reaction (HER) with a low overpotential of 31 mV at 10 mA cm−2. A record high Faradaic efficiency (97.7%) for formate production of GOR is delivered at 1.35 V (vs RHE). Impressively, a two‐electrode electrolyzer capitalizing on the Mn‐CoN@C/NF as catalysts reaches 800 mA cm−2 at 1.83 V, delivering an electricity‐saving efficiency of 15.0% compared to pure water splitting. DFT calculations substantiate that Mn species within Mn‐CoN not only optimize hydrogen adsorption kinetics for HER, but also elevate Co3+ active sites' density for GOR. This work offers an energy‐saving and efficient electrosynthesis avenue for coproduction of valuable chemicals. [ABSTRACT FROM AUTHOR]

As the key principle in the literary and artistic world of the Mao Zedong era, "going into the thick of life" is far more than a mere approach to discovering material and themes for writing. The path of "going into the thick of life" set upon the premise of "diving deep into work" stems from the two principles established together in Mao Zedong's "Talks at the Yan'an Forum on Literature and Art" (Zai Yan'an wenyi zuotanhui shang de jianghua) and the rectification movement: reform of revolutionaries and intellectuals through "combination with the masses of workers, peasants and soldiers," and second, reform of revolutionary politics via the "mass line," designed to trigger the creativity of the masses. Each of these two principles is the precondition of the other. On the one hand, "going into the thick of life" based on the premise of "diving deep into work" offers the subjective perspective of the revolutionaries deeply involved in the local social reform--their difficulties, frustrations, and necessary self-adjustments when revolutionary ideals and the subjective attitudes towards policies conflicted with the realities of practice. On the other hand, different from official chronicles and local archives, records of their actions and real observations provide us with a sort of experiential perspective from the grass-roots level which appears more rich, complete and vivid, enabling us to view the problems of revolution from the perspective of the social system in operation, on top of the possibility of seeing the society from the subjective stance of revolution. The detailed records of the 1953 cooperative establishment presented in Xu Guangyao riji (Xu Guangyao diary) offers us a fine example of a text about "going into the thick of life." Despite the failure of his writing plan, all of the harassment and frustrations recorded in the diary possess special epistemological value, offering a clear-cut picture of the friction and interaction between the logic of real-life practice and the logic of action based upon ideology, which constituted the "reality" of revolutionary practice in the Mao era. Meanwhile, it hints as well at the peculiarity and challenges of the requirements set upon literature of realism in the Mao era. [ABSTRACT FROM AUTHOR]

Energy shortage and environmental pollution have become the most serious problems faced by human beings in the 21st century. Looking for advanced clean energy technology to achieve sustainable development of the ecological environment has become a hot spot for researchers. Nitrogen-based substances represented by urea are environmental pollutants but ideal energy substances. The efficiency of urea-based energy conversion technology mainly depends on the choice of catalyst. The development of new catalysts for urea oxidation reaction (UOR) has important application value in the field of waste energy conversion and pollution remediation based on UOR. In this work, four metal–organic framework materials (MOFs) were synthesized using ultrasound (NiCo-UMOFs) and hydrothermal (NiCo-MOFs, Ni-MOFs and Co-MOFs) methods to testify the activity toward UOR. Materials prepared using the hydrothermal method mostly form large and unevenly stacked block structures, while material prepared using ultrasound forms a layer-by-layer two-dimensional and thinner structure. Electrochemical characterization shows NiCo-UMOFs has the best electrocatalytic performance with an onset potential of 0.32 V (vs. Ag/AgCl), a Tafel slope of 51 mV dec−1, and a current density of 13 mA cm−2 at 0.5 V in a 1 M KOH electrolyte with 0.7 M urea. A prolonged urea electrolysis test demonstrates that 45.4% of urea is removed after 24 h. [ABSTRACT FROM AUTHOR]
