ABSTRACT
Optimizing the electrode/electrolyte interface structure is the key to realizing high-voltage Li-metal batteries (LMBs). Herein, a functional electrolyte is introduced to synergetically regulate the interface layer structures on the high-voltage cathode and the Li-metal anode. Saccharin sodium (NaSH) as a multifunctional electrolyte additive is employed in fluorinated solvent-based electrolyte (FBE) for robust interphase layer construction. On the one hand, combining the results of ex-situ techniques and in-situ electrochemical dissipative quartz crystal microbalance (EQCM-D) technique, it can be seen that the solid electrolyte interface (SEI) layer constructed by NaSH-coupled fluoroethylene carbonate (FEC) on Li-metal anode significantly inhibits the growth of lithium dendrites and improves the cyclic stability of the anode. On the other hand, the experimental results also confirm that the cathode-electrolyte interface (CEI) layer induced by NaSH-coupled FEC effectively protects the active materials of LiCoO2 and improves their structural stability under high-voltage cycling, thus avoiding the material rupture. Moreover, theoretical calculation results show that the addition of NaSH alters the desolvation behavior of Li+ and enhances the transport kinetics of Li+ at the electrode/electrolyte interface. In this contribution, the LiCoO2 ÇLi full cell containing FBE+NaSH results in a high capacity retention of 80% after 530 cycles with a coulombic efficiency of 99.8%.
ABSTRACT
As a crucial external capital force of enterprises, common institutional ownership plays an essential role in enterprise innovation and development. However, few studies have focused on the impact and underlying impact mechanisms of common institutional ownership on the digital transformation of enterprises. Hence, this study uses Python to analyse the annual reports of listed companies from 2007 to 2021 and constructs measures of enterprise digital transformation. Then, based on panel fixed effects Poisson regression, this study examines the influence of common institutional ownership on enterprise digital transformation by using theoretical logic and empirical evidence. The results reveal that common institutional ownership significantly inhibits enterprise digital transformation; this result remains valid after a series of endogeneity and robustness tests, thereby indicating that common institutional ownership exerts a collusion fraud effect. The mechanism analysis shows that common institutional ownership hampers enterprise digital transformation mainly by increasing monopoly power within the market, aggravating information asymmetry between enterprise insiders and outsiders, and intensifying executive self-dealing. Further analysis reveals that the inhibitory effect of common institutional ownership on digital transformation is more significantly negative in the case of non-state-owned enterprises versus state-owned enterprises. This study expands the research on the factors influencing enterprise digital transformation. The results provide a helpful reference for further improving institutional investors' ownership structures and promoting high-quality enterprise development.
ABSTRACT
BACKGROUND: Societies around the world are aging. Widespread aging creates problems for social services and health care practices. In this light, research on connected health (CH) is becoming essential. CH refers to a variety of technological measures that allow health care to be provided remotely with the aim of increasing efficiency, cost-effectiveness, and satisfaction on the part of health care recipients. CH is reshaping health care's direction to be more proactive, more preventive, and more precisely targeted and, thus, more effective. CH has been demonstrated to have great value in managing and preventing chronic diseases, which create huge burdens on health care and social services. In short, CH provides promising solutions to diseases and social challenges associated with aging populations. However, there are many barriers that need to be overcome before CH can be successfully and widely implemented. OBJECTIVE: The research question of this study is as follows: How can CH facilitate smart, remote, and targeted health care? The objective is to identify how health care can be managed in more comprehensive ways, such as by providing timely, flexible, accessible, and personalized services to preserve continuity and offer high-quality seamless health care. METHODS: A qualitative approach was used based on 60 multistage, semistructured stakeholder interviews. RESULTS: The results can be divided into two functions of CH: ecosystem and platform. On the one hand, the interviews enabled the authors to develop a stakeholder classification and interaction diagram. These stakeholders interacted sequentially to provide technology-based content to end users. On the other hand, interviewees reflected on how CH serves as a platform to address remote monitoring and patient self-management. In the Discussion section, three innovation strategies are discussed to reflect the manner in which CH promotes smart, timely, and precise health care. CONCLUSIONS: This study indicates that it is essential to continually revise CH business models, given the ongoing and rapid changes in technology across groups of CH stakeholders. We also found that global trends toward smart, timely, and precise health care shape what individuals expect from products and services, providing firms with unique opportunities for growth.

Background: The evolution of names, from "medical informatics" to "connected health", implies that the evolvement of technology in health care has been shifted from technology-oriented to healthcare-oriented implementation. Connected healthcare, a healthcare platform of remote monitoring and self-management through technological measures, is suggested to contribute to the efficiency, cost-effectiveness, and satisfaction of healthcare recipient enhancement. However, limited understanding of related connected health (CH) terminology may constrain its implementation. Whether CH is a buzzword only or a practice that can contribute to an aging society is controversial. Objective: This study aims to distinguish CH-related terminology and to identify the trend of CH through reviewing its definition, initiation, development, and evolvement, in order to offer management insights and implications. The objective is to understand what is connected and who is cared about in the connected health model so that better applications can be addressed for the benefit of society. Method: This study reviews the evolution of names, from "medical informatics" in the 1970s to "connected health" after 2000, as well as relevant literature of CH, including e-health, telemedicine, telehealth, telecare, and m-health, to discover the trend of technology-related healthcare innovations. Results: The current status and issues facing accessibility, quality, and cost were presented. Its future trends will be explored through reviewing how changes in healthcare are managed, in addition to its operation and practice. Pre-conditions and requirements for implementing CH are identified to select a typical case to study. Findings suggest that areas with a complete business ecosystem-isolated locations, advanced information technology, aging in population, integrated health, and social care system-are prevalent for designing friendly CH environments. Conclusion: The evidence and tendency of technological convergence create a demand for innovation and partnering with start-up companies that offer a competitive advantage in innovation.
