The design of efficient and low-cost multifunctional electrocatalysts for hydrogen evolution reaction(HER), oxygen evolution reaction(OER) and oxygen reduction reaction(ORR) is critical for the development of clean energy. Two-dimensional(2D) carbon-based nano-materials are becoming more and more popular in heterogeneous catalysis due to their cost-effective and multi-scale tunability as single-atom catalysis(SACs) substrates. In this paper, by using first-principles calculation, we designed and demonstrated a novel macropore T-carbon [110](TC) monolayer as 2D electrocatalyst substrate for HER/OER/ORR, and the synergistic modification of the transition metal and nonmetal atoms(TM-X) were investigated to enhance the multifunctional electrocatalytic performance. We screened out the Co embedded in N-doped TC(Co3@N-TC) from 30 TM@X-TC monolayers as a trifunctional electrocatalysts, which exhibits superior performance for HER/ORR/OER on both thermodynamic and kinetic scales, and with excellent thermal and electrochemical stability. Then, the TC monolayer is naturally macropore with a diameter of 5.36 A and exhibits excellent adsorption capacity for the intermediates and products of the redox reactions. Moreover, we revealed the origin of the electrocatalytic activity using the crystal orbital Hamilton population(COHP) and the molecular orbitals(MOs). The d orbital of Co3@N-TC is significantly hybridized with the p orbital of the intermediates, so that the lone electrons initially occupied in the antibonding state pair up and occupy the downward bonding state, allowing *OH to be appropriately adsorbed onto the TC monolayer. This work not only demonstrates that the TM@X-TC monolayer is a superior synergistic trifunctional electrocatalyst, but also reveals a macropore monolayer material with potential applications in electrocatalysis.

引用

Open Journal of Applied Sciences 2024年第2期14卷 320-329页

作者： shuli gao Yanli Guo College of Arts and Sciences Beijing Union University Beijing China

With the arrival of the big data era, the modern higher education model has undergone radical changes, and higher requirements have been put forward for the data literacy of college teachers. The paper first analyzes the connotation of teacher data literacy, and then combs through the status quo and dilemmas of teachers’ data literacy ability in applied universities. The paper proposes to enhance the data literacy ability of teachers from the perspective of organizational learning. Through building a digital culture, building a data-driven teaching environment, and constructing an interdisciplinary learning community to further promote the application of the theory and practice of datafication inside and outside the organization, and ultimately improve the quality of teaching.

Open Journal of Applied Sciences 2023年第6期13卷 832-846页

作者： Yiying You shuli gao Arts and Sciences College Beijing Union University Beijing China

Organizational resilience is an important core element for today’s companies to turn around in the VUCA1 environment. It can strengthen the ability of companies to adapt and help them to regain their strength in adversity. In this paper, based on CNKI database and WOS (Web of Science) database search to get the Chinese and foreign literature (special reference to English literature) for the whole year 2000-2022, and use bibliometric method to analyze the hot spots and research trends in the field of organizational resilience research, the results found that: 1) there is more foreign-language research literature on tissue toughness than Chinese-language research literature, and the number of articles published in Chinese journals on this topic has entered a rapid growth phase since 2011, and the number of articles published both at home and abroad is generally on the rise, and tissue toughness is increasingly becoming a research hotspot;2) from the cooperation of existing published literature, the cooperation network between research scholars is generally more dispersed, and domestic scholars are mostly independent;3) From the viewpoint of research hotspots, individual resilience, supply chain resilience and risk management are hotspots in foreign organizational resilience research;domestic research mainly focuses on the connotation and measurement dimensions of organizational resilience, individual resilience and dynamic capabilities.

Research Progress and Trends in Technology Affordances Research: A Knowledge Graph Analysis Based on CiteSpace

引用

Journal of Computer and Communications 2023年第7期11卷 174-190页

作者： Cai Lu shuli gao College of Arts and Sciences Beijing Union University Beijing China

Technology affordances are a method for technology users to carry out actions based on the possibilities provided by a certain technology. In order to systematically grasp the research hotspots and evolution of technology affordances at home and abroad, and clarify the characteristics and development direction of technology affordances research in China, we use CiteSpace software to visualize and analyze the research literature on technology affordances at home and abroad. The research results of technology affordances at home and abroad are increasing, and the number of scholars who have researched technology affordances is large, but the cooperation among authors is generally scattered;among foreign research on technology affordances, information technology, knowledge technology, artificial intelligence, digital technology and web 2.0 are the hot spots of research;among domestic research on technology affordances, the connotation of technology affordances, social media, interaction design and user purchase are the hotspots;there are differences in the research frontiers of technology affordances research at home and abroad, but they all focus on the field of social media.

A mini-vane four-rod radio frequency quadruple (RFQ) accelerator has been built for neutron imaging. The RFQ will operate at 201.5 MHz, and its length is 2.7 m. The original electric field distribution along the electrodes is not flat. The resonant frequency needs to be tuned to the operating value. And the frequency needs to be compensated for temperature change during high power RF test and beam test. As tuning such a RFQ is difficult, plate tuners and stick tuners are designed. This paper will present the tuners design, the tuning procedure, and the RF properties of the RFQ.

Journal of Biosciences and Medicines 2021年第2期9卷 33-41页

作者： shuli gao Yiping Liu Yuxin Cai Jixin Jiao Jianqing Bi Business College Beijing Union University Beijing China

In recent years, hospice care in Beijing has developed rapidly. In order to further promote the development of hospice care in Beijing, this paper first analyzes the current situation of hospice care in Beijing, and then analyzes the existing problems of hospice care in Beijing, such as insufficient funds, lack of medical staff, no unified public information platform and low acceptance of hospice care. In view of the existing problems, the paper puts forward relevant policy suggestions for the development of hospice care in Beijing, such as increasing financial support, strengthening the propaganda and education of hospice care, strengthening the training of professional talents, improving the voluntary service system, formulating reasonable access standards, and building a unified public information platform, so as to further promote the effective, healthy and rapid development of hospice care in Beijing development.
