13. The Role of Socioeconomic Status Gradients for the Child's Developmental Health

Author

Zhang, Wangyang, Qin, Guomin, Zhao, Zijian, Liu, Wenhao, Zhang, Shiyu, and Kumar, Priyan Malarvizhi

Abstract

Gradients across socioeconomic status occur for many children's health and improvement in high-income countries. The objective is to explore infant growth and child development in four developed countries around the socioeconomic landscape. In this paper, Structural Equation Modeling (SEM) enhances the socioeconomic status gradients for the child's developmental health. The proposed model develops the socioeconomic status is related to a huge list of health issues, including low birth weight, cardiovascular diseases, hypertension, arthritis, diabetes, and cancer, regardless of whether it is determined by income, education, or profession. This is a global phenomenon, seen in countries with low, medium, and high incomes. The size of disparities found in scores and percentiles across neighborhoods is comparable to the results of more developed growth forecasters such as sex. These results have significant consequences for the nature of tailored, efficient, and timely programs to support early childhood success.

24. Hierarchical carbon structures for advanced high areal capacity lithium-ion battery electrodes

Abstract

The ever-growing energy demand from modern portable electronics and electric vehicles calls for a matching development in lithium-ion batteries (LIBs) that offer high power density, energy density, and long cycle life. However, LIBs based on traditional layered metal oxide cathodes and graphite anodes are quickly approaching their specific energy limits. The exploration of advanced electrode architectures provides a novel route to improving the energy density of LIBs and is often overlooked. This PhD thesis investigates the design, fabrication, and testing of structurally engineered and high areal capacity LIB electrodes based on hierarchical carbon structures such as carbon nanotubes (CNTs). Firstly, (surface-modified) direct-spun CNT mats are proposed as conductive scaffolds for lithium metal anodes (LMAs), which are desirable for next-generation batteries because of their ultra-high energy density. However, the practical applications of LMAs are hindered by the inhomogeneous Li dendrite formation during cycling which leads to poor efficiency and safety issues. The proposed electrode provides ample Li nucleation sites, reduces the local current densities, and promotes uniform Li plating/stripping at selective locations, thus achieving coulombic efficiencies (CEs) of 98-99% for over 130 cycles in CNT|Li half-cells (lithiation capacity: 2.0 mA h cm-2, current density: 1.0 mA cm-2). Next, a freestanding carbon fibre paper with carbon fillers (CFP) electrode is proposed with a novel dual charge storage mechanism - it acts both as a host for Li intercalation and as a conductive, porous, and lithiophilic 3D scaffold for Li plating/stripping. The CFP electrode exhibits excellent long-term cycling stability, as evidenced by CEs of over 99.5% on the 250th cycle in CFP|Li half-cells (lithiation capacity: 1.5 mA h cm-2, current density: 0.5 mA cm-2). Notably, both the CNT mat and CFP electrodes can be manufactured at an industrial scale, showing real promises for practical applications. Lastly, thick electrodes can help improve the energy density of LIBs by increasing the ratio of electrochemically active materials in a battery cell, but they often suffer from poor rate performances that is caused by the increase of various internal resistance terms associated with respective charge storage mechanisms, as well as manufacturing challenges. Here, ultra-thick lithium titanate (LTO) electrodes based on nanostructured CNT honeycomb conductive backbones (LCHB) are proposed - the hierarchical CNT honeycombs help improve Li-ion diffusion, provide more electrically conductive pathways, increase electrochemically active surface area, and offer mechanical support. High aspect ratio (over 1000) CNT honeycomb backbones of over 1 mm tall are successfully manufactured, and subsequently LCHB electrodes with areal loadings of over 25 mg cm-2 are successfully fabricated. The LCHB electrodes demonstrated superior rate performance (over 50% at 2 C as compared to less than 10% for planar electrode with similar areal loading) and longer cycle life (over 230 cycles until 10% capacity is lost as compared to less than 15 cycles for planar electrodes). Furthermore, EIS results revealed LCHB electrodes with low frequency resistance term (consists of charge transfer and Li ion transfer resistances) an order of magnitude lower than planar electrodes.

28. Analysis of the factors influencing the promotion of stone sculpture art based on social media communication dynamics

Abstract

This paper first focuses on the design elements and digital platforms of stone carving art and then discusses the dissemination of stone carving art on social media platforms. Secondly, a social media propagation dynamics modeling of stone sculpture art promotion is proposed, and the degree distribution of stone sculpture art promotion in the BA scale-free network is calculated by the social media network model and propagation evolution model. Finally, the kinetic analysis of social media on stone carving art promotion by different influencing factors and information dissemination stages is explored. The results show that when the user recognizes stone carving art as Ii(0) = 0.7 the larger the value Ii = (0), the greater the user’s propensity to spread stone carving art promotion information and the greater the rate of stone carving art promotion information dissemination. Through the in-depth combination of social media and stone carving art, this paper has important practice and significance for the protection and inheritance of stone carving art and for improving its influence and popularity.
