"Made in China" Reflects Low Added-value in Global Industrial Divisions

The Belle Corporation is a Chinese domestic shoe maker and seller. It also belongs to an industry that has come to be representative of the ubiquitous "Made in China" label. One of the main reasons the company is favored by global investors is due to its unique business pattern-a pattern that sets manufacturing as its base and is active in exploring industrial chain downstream links and establishing its own individual retail channels. Ever since its first inception in the stock market, Belle has set out to acquire several upstream manufacturing companies, indicating its desire for increasing channel terminals. Using a vertically integrated competition strategy, Belle stands out amongst its rivals as being particularly successful in the non-mainstream manufacturing sector. Consequently, its business practices can be used as a model for other domestic manufacturing companies in their efforts to meet the challenges posed by globalization.

Design and synthesis of thermally stable single atom catalysts for thermochemical CO_(2) reduction

The continuous and excessive emission of CO_(2)into the atmosphere presents a pressing challenge for global sustainable development.In response,researchers have been devoting significant efforts to develop methods for converting CO_(2)into valuable chemicals and fuels.These conversions have the potential to establish a closed artificial carbon cycle and provide an alternative resource to depleting fossil fuels.Among the various conversion routes,thermochemical CO_(2)reduction stands out as a promising candidate for industrialization.Within the realm of heterogeneous catalysis,single atom catalysts(SACs)have garnered significant attention.The utilization of SACs offers tremendous potential for enhancing catalytic performance.To achieve optimal activity and selectivity of SACs in CO_(2)thermochemical reduction reactions,a comprehensive understanding of key factors such as single atom metal-support interactions,chemical coordination,and accessibility of active sites is crucial.Despite extensive research in this field,the atomic-scale reaction mechanisms in different chemical environments remain largely unexplored.While SACs have been found successful applications in electrochemical and photochemical CO_(2)reduction reactions,their implementation in thermochemical CO_(2)reduction encounters challenges due to the sintering and/or agglomeration effects that occur at elevated temperatures.In this review,we present a unique approach that combines theoretical understanding with experimental strategies to guide researchers in the design of controlled and thermally stable SACs.By elucidating the underlying principles,we aim to enable the creation of SACs that exhibit stable and efficient catalytic activity for thermochemical CO_(2)reduction reactions.Subsequently,we provide a comprehensive overview of recent literature on noble metal-and transition metal-based SACs for thermochemical CO_(2)reduction.The current review is focused on certain CO_(2)-derived products involving one step reduction only for simplicity and for better understanding the SACs enhancement mechanism.We emphasize various synthesis methods employed and highlight the catalytic activity of these SACs.Finally,we delve into the perspectives and challenges associated with SACs in the context of thermochemical CO_(2)reduction reactions,providing valuable insights for future research endeavor.Through this review,we aim to contribute to the advancement of SACs in the field of thermochemical CO_(2)reduction,shedding light on their potential as effective catalysts and addressing the challenges that need to be overcome for their successful implementation as paradigm shift in catalysis.

Restoring the plant productivity of heavy metal-contaminated soil using phosphate sludge,marble waste,and beneficial microorganisms

Assisted natural remediation(ANR)has been highlighted as a promising,less expensive,and environmentally friendly solution to remediate soil contaminated with heavy metals.We tested the effects of three amendments(10%compost,C;5 or 15%phosphate sludge,PS5 and PS15;and 5 or 15%marble waste,MW5 and MW15)in combination with microorganism inoculation(rhizobacteria consortium alone,mycorrhizae alone,and the two incombination)on alfalfa in contaminated soil.Plant concentrations of Zn,Cu,and Pb were measured,along with proline and malondialdehyde production.The microbiological and physicochemical properties of the mining soil were evaluated.Application of the amendments allowed germination and promoted growth.Inoculation with the rhizobacteria consortium and/or mycorrhizae stimulated plant growth.PS and MW stimulated the production of proline.Inoculation of alfalfa with the rhizobacteria-mycorrhizae mixture and the application of MW allowed the safe cultivation of the legume,as shown by the low concentrations of metals in plant shoots.Zn and Pb concentrations were below the limits recommended for animal grazing and accumulated essentially in roots.Soil analyses showed the positive effect of the amendments on the soil physicochemical properties.All treatments increased soil p H(around 7),total organic carbon,and assimilable phosphorus content.Notably,an important decrease in soluble heavy metals concentrations was observed.Overall,our findings revealed that the applied treatments reduced the risk of metal-polluted soils limiting plant growth.The ANR has great potential for success in the restoration of polymetallic and acidic mining soils using the interaction between alfalfa,microorganisms,and organomineral amendments.
