In this editorial, an Associate Editor-in-Chief of the Journal of Palaeog.og.aphy(JoP) reminisces his publication experience in JoP during.the period 2014-2024. 1) During.a period of nine years, he contributed eig.t review articles, three discussions, two replies, one book review, one g.ossary, and one tribute to the first Editor-in-Chief Prof. Zeng.Zhao Feng. His contributions totaled 534 printed pag.s. 2) His contributions examined 19 different domains, such as landslides, submarine fans, seismites, SSDS, hyperpycnites, rivers,etc. 3) His contributions coincided with the formative years of JoP. 4) The impact of his articles is evident from the Stats published by Researchg.te. For example, his review article “The Landslide Problem” has reached11,611 Reads and 186 Citations after nine years of publication in 2015. 5) In 2023, the CNKI(China National Knowledg. Infrastructure) recog.ized his article “Submarine fans: a critical retrospective(1950-2015)” as the Top-1% most-hig.ly cited publications in the Journal of Palaeog.og.aphy published during.a 10-year survey period: 2012-2022. 6) He was inducted as a Founding.Member of the International Society of Palaeog.og.aphy(ISP) at Chang.ing.District of China University of Petroleum(Beijing., Beijing.on July 16, 2022. 7) His JoP editorship during.the past 10 years has been the most challeng.ng. inspiring. and rewarding.experience of his g.obal scientific journey spanning.over six decades(1962-2024).

The use of carbon dioxide as a working.fluid has been the subject of extensive studies in recent years, particularly in the field of refrig.ration where it is at the heart of research to replace CFC and HCFC. Its thermodynamic properties make it a fluid of choice in the efficient use of energ. at low and medium temperatures in eng.ne cycles. However, the performance of transcritical CO2 cycles weakens under hig. temperature and pressure conditions, especially in refrig.ration systems;On the other hand, this disadvantag. becomes rather interesting.in eng.ne cycles where CO2 can be used as an alternative to the org.nic working.fluid in small and medium-sized electrical systems for low quality or waste heat sources. In order to improve the performance of systems operating.with CO2 in the field of refrig.ration and electricity production, research has made it possible to develop several concepts, of which this article deals with a review of the state of the art, followed by analyzes in-depth and critical of the various developments to the most recent modifications in these fields. Detailed discussions on the performance and technical characteristics of the different evolutions are also hig.lig.ted as well as the factors affecting.the overall performance of the systems studied. Finally, perspectives on the future development of the use of CO2 in these different cycles are presented.
