“…[42] The integration of green walls into modern society has various effects, such as reducing the urban heat island effect, saving electrical energy, reducing city noise, reducing CO 2 generation rate, and removing fine dust. [42][43][44][45][46][47][48][49][50] However, a thick layer of soil or artificial substrate for planting plants and a structure to support this layer are problematic requirements for green walls. In our experiment, hydrogel was attached to the concrete, and the rhizoid of bryophyte was rooted in the hydrogel without soil or any facilities (Figure 6a,c).…”

superior properties of the substrate (e.g., strength, stiffness, and toughness). [2] This has allowed for applications in new fields, such as in engineering and medicine. [1,3] Such new applications include coatings of antifouling-antimicrobial hydrogels for infection prevention, [4] hydrogel adhesion to metal substrates for marine antifouling, [5] coatings of mechanically matched hydrogels to improve the biocompatibility of neural implants, [6] chemical-sensing hydrogel interferometerbased sensing platforms, [7] and glass fiber hydrogel coatings for selective oil-water separation. [8] Hydrogel coatings can be also applied to concrete materials. Concrete is widely used as a building material due to its low cost, high strength, good durability, plasticity, and versatility. [9][10][11] However, concrete structures are vulnerable to corrosion and weathering by the external environment (freezing, acid rain, etc.) due to their hydrophilicity and porous structure. [10] Many researchers have put substantial effort into fixing concrete damage. Xu et al. coated concrete with a colorful superhydrophobic material. [10] The coated concrete had enhanced anti-icing, anticorrosion, and self-cleaning properties. Song et al. coated concrete with microcapsules containing a healing agent to prevent the deterioration of the concrete. [12] In addition, because of the excellent properties of concrete, many concrete structures have been built in urban areas. This has caused environmental problems such as high energy consumption in city centers, global warming caused by refrigerants in cooling equipment, ozone layer depletion, urban heat island phenomenon, and poor indoor air quality. [13] Feng et al., [13] Cui et al., [14] and Rotzetter et al. [15] stated there may be an energy saving effect by cooling buildings using the evaporation heat of hydrogel. Since concrete structures and the external environment are interconnected, research to address the issues with concrete structures is urgently needed. In particular, in light of numerous studies, hydrogels are considered a promising material to solve the problem between the concrete and the environment.In our previous study, we developed a NC hydrogel that strongly adheres to concrete. [16] In general, for strong adhesion between the hydrogel and the substrate, surface modification of the substrate and the formation of a primer layer are essential. [17,18] On the other hand, nanosilicate-based hydrogels have excellent coating durability without pretreatment due to the following factors: (1) NC hydrogel adheres to concrete by chemical reaction between nanosilicate and portlandite. [19] Hydrogels can be coated on various substrates to add a variety of functions to the substrates. In this study, hydrogel is coated on concrete that widely used as a building material. In general, in order to coat hydrogel on concrete, a prior process such as surface modification or primer layer coating is essential. However, this process is time consuming and requires the use of toxic chemicals. In this study,...

“…Therefore, if the litter and pruning of vegetation in cities are properly treated and disposed, they will contribute more to the carbon sequestration than the litter in natural ecosystems (Wen et al 2010). Reyhani et al (2022) also found that plants can recycle the carbon released during production after 12 or 14 years, and selecting plants suitable for local climatic conditions not only reduces the use of nutrients and irrigation, but also minimize the negative impacts of the operational phase. Marchi et al (2015) found that herbs grow to the end of their lifespan and compost the green waste and add it to the soil.…”

Green ecological communities have garnered significant interest due to their role in providing urban ecosystem services, and community greening plays a pivotal role in urban environmental enhancement. In the context of carbon neutrality-oriented goals, it is imperative to acknowledge the significance of various landscape designs in carbon sequestration within community greening initiatives. However, there is currently a lack of consideration for landscape designs that promote high carbon sequestration in community greening projects. Our research with literature research and experimental measurement data as data sources, established a database of carbon sequestration of 138 common vegetation species in Shanghai. Based on the vertical vegetation structure within landscape design, we propose seven modular planting structures that reflect the carbon sequestration potential of high-capacity plants within different community green spaces. Our findings reveal substantial variations in carbon sequestration among different tree species within arbor and shrub categories, whereas the differences in carbon sequestration among various herbaceous plants per unit area are comparatively smaller. Among the different combination patterns, the highest carbon sequestration is achieved by the vegetation configuration of the three-layer structure pattern, and the combination of arbors, shrubs and grasses can maximize the effective use of space. This study holds significant importance in optimizing the utilization of limited green spaces within communities and enhancing the carbon sequestration benefits of community landscapes. Ultimately, these efforts contribute significantly to Shanghai's journey toward carbon neutrality.
