As a promising energy carrier, ammonia synthesis by electrocatalytic nitrogen reduction reaction (eNRR) is a promising green and low‐carbon ammonia synthesis strategy that can replace the traditional Haber–Bosch process. However, the development of eNRR processes is mainly severely constrained by competitive hydrogen evolution reaction (HER), and the corresponding strategies to inhibit this adverse side reaction to obtain high eNRR selectivity are still limited. In addition, for this complex reaction involving gas–liquid–solid three‐phase interface and proton/electron transfer, it is great significance to analyze and summarize the existing inhibition HER strategies from the viewpoint of dynamics. In view of this, this work reviews proton supply/filtration regulation strategy in catalytic system, allowing a systematic survey of the literature focusing on interface membrane regulation (inorganic membrane and organic membrane), electrolyte regulation (metal‐mediated strategy and electrolyte ion regulation strategy) and system device design (electrode structure design and electrolytic cell device design). Constructive catalytic system design guidance is also suggested to inhibit hydrogen evolution and improve NH3 selectivity, aiming for scalable and economically feasible applications.

Objective: Currently, acupuncture for shoulder pain has been widely used in clinical and scientific research worldwide, but the bibliometric literature on acupuncture for shoulder pain is still scarce. This study reviews the application of acupuncture in the treatment of shoulder pain over the past 15 years, to analyze the current state of research, research hotspots, and trends. The article can also provide a reference for future research. Methods: This paper searches the core collection of the Web of Science database for publications related to acupuncture therapy for shoulder pain between 2008 and 2022. And the data were visualized and analyzed using VOSviewer and CiteSpace for annual publications, countries, institutions, journals and co-cited journals, authors and co-cited authors, keywords, and emergent keywords. Results: A total of 135 papers were included, with an overall increasing trend in the number of annual publications. The country with the highest centrality in publishing articles is the United States (0.28). In terms of research institutions, Kyung Hee University has the highest number of publications (18).
