3A state-of-the-art review on shallow geothermal ventilation systems with thermal performance enhancement-system classifications,advanced technologies and applications显示文摘Geothermal energy with abundance and large quantity can partially cover building heating/cooling loads and promote the carbon-neutrality transitions.Shallow geothermal ventilation(SGV)system,with a little initial in-vestment cost,is one of promising technologies to partly replace the conventional air-conditioning system for air pre-cooling/pre-heating.This paper reviews applications of SGV system for improving thermal performance over latest two decades,which mainly includes the reclassification of SGV system,coupling with other advanced energy-saving technologies,application potentials for building cooling/heating under various weather conditions.Heat transfer mechanism and mathematical modelling techniques have been reviewed,together with in-depth analysis on current research trends,existing limitations,and recommendations of SGV system.Phase change materials,with considerable latent energy density,can stabilize the thermal performance with high reliability.The review identifies that optimization designs and advanced approaches need to be investigated to address the existing urgent issues of SGV system(e.g.,large land occupation,difficulty in centralized collection of condensate water timely for horizontal buried pipe,bacteria growth,polluted supply air,and high construction cost for ver-tical buried pipe).A plenty of studies show that the SGV system could greatly expand the application scope and improve system energy efficiency by combining with other energy-saving technologies.This paper will provide some guidelines for the scientific researchers and engineers to keep track on recent advancements and research trends of SGV system for the building thermal performance enhancement and pave path for future research works.Zhengxuan Liu Mingjing Xie Yuekuan Zhou Yingdong He Lei Zhang Guoqiang Zhang Dachuan Chen 2023Energy and Built Environment2023,4,2:1
4Stability of Sn-Pb mixed organic–inorganic halide perovskite solar cells:Progress,challenges,and perspectives显示文摘The exploration of low bandgap perovskite material to approach Shockley-Queisser limit of photovoltaic device is of great significance,but it is still challenging.During the past few years,tin–lead(Sn-Pb)mixed perovskites with low bandgaps have been rapidly developed,and their single junction solar cells have reached power conversion efficiency(PCE)over 21%,which also makes them ideal candidate as low bandgap sub-cell for tandem device.Nevertheless,due to the incorporation of unstable Sn^(2+),the stability issue becomes the vital problem for the further development of Sn-Pb mixed perovskite solar cells(PSCs).In this review,we are dedicated to give a full view in current understanding on the stability issue of SnPb mixed perovskites and their PSCs.We begin with the demonstration on the origin of instability of Sn-Pb mixed perovskites,including oxidation of Sn^(2+),defects,and interfacial layer induced instability.Sequentially,the up-to-date developments on the stability improvement of Sn-Pb mixed perovskites and their PSCs is systematically reviewed,including composition engineering,additive engineering,and interfacial engineering.At last,the current challenges and future perspectives on the stability study of Sn-Pb mixed PSCs are discussed,which we hope could promote the further application of Sn-Pb mixed perovskites towards commercialization.Shaoshen Lv Weiyin Gao Yanghua Liu He Dong Nan Sun Tingting Niu Yingdong Xia Zhongbin Wu Lin Song Chenxin Ran Li Fu Yonghua Chen 2022Journal of Energy Chemistry2022,31,2:1

10Artificial intelligence powered large-scale renewable integrations in multi-energy systems for carbon neutrality transition: Challenges and future perspectives显示文摘The vigorous expansion of renewable energy as a substitute for fossil energy is the predominant route of action to achieve worldwide carbon neutrality. However, clean energy supplies in multi-energy building districts are still at the preliminary stages for energy paradigm transitions. In particular, technologies and methodologies for large-scale renewable energy integrations are still not sufficiently sophisticated, in terms of intelligent control management. Artificial intelligent (AI) techniques powered renewable energy systems can learn from bioinspired lessons and provide power systems with intelligence. However, there are few in-depth dissections and deliberations on the roles of AI techniques for large-scale integrations of renewable energy and decarbonisation in multi-energy systems. This study summarizes the commonly used AI-related approaches and discusses their functional advantages when being applied in various renewable energy sectors, as well as their functional contribution to optimizing the operational control modalities of renewable energy and improving the overall operational effectiveness. This study also presents practical applications of various AI techniques in large-scale renewable energy integration systems, and analyzes their effectiveness through theoretical explanations and diverse case studies. In addition, this study introduces limitations and challenges associated with the large-scale renewable energy integrations for carbon neutrality transition using relevant AI techniques, and proposes further promising research perspectives and recommendations. This comprehensive review ignites advanced AI techniques for large-scale renewable integrations and provides valuable informational instructions and guidelines to different stakeholders (e.g., engineers, designers and scientists) for carbon neutrality transition.Zhengxuan Liu Ying Sun Chaojie Xing Jia Liu Yingdong He Yuekuan Zhou Guoqiang Zhang 2022Energy and AI2022,10,4:1

12Chiral cation promoted interfacial charge extraction for efficient tin-based perovskite solar cells显示文摘Pb-free Sn-based perovskite solar cells(PSCs) have recently made inspiring progress, and power conversion efficiency(PCE) of 14.8% has been achieved. However, due to the energy-level mismatch and poor interfacial contact between commonly used hole transport layer(i.e., poly(3,4-ethylenedioxythio phene):poly(styrene sulfonate), PEDOT:PSS) and FASnI_(3) film, it is still challenging to effectively extract holes at the interface. Owing to the p-type nature of Sn-based perovskites, the efficient hole extraction is of particular significance to improve the PCE of their solar cells. In this work, for the first time, the role of chiral cations, a-methylbenzylamine(S-/R-/rac-MBA), in promoting hole transportation of FASnI_(3)-based PSCs is demonstrated. The introduction of MBAs is found to form 2D/3D film with lowdimensional structures locating at PEDOT:PSS/FASnI_(3) interface, which facilitates the energy level alignment and efficient charge transfer at the interface. Importantly, chiral-induced spin selectivity(CISS)effect of R-MBA_(2)SnI_(4)induced by chiral R-MBA cation is found to further assist the specific interfacial transport of accumulated holes. As a result, R-MBA-based PSCs achieve decent PCE of 10.73% with much suppressed hysteresis and enhanced device stability. This work opens up a new strategy to efficiently promote the interfacial extraction of accumulated charges in working PSCs.Weiyin Gao He Dong Nan Sun Lingfeng Chao Wei Hui Qi Wei Hai Li Yingdong Xia Xingyu Gao Guichuan Xing Zhongbin Wu Lin Song Peter Müller-Buschbaum Chenxin Ran Yonghua Chen 2022Journal of Energy Chemistry2022,31,5:0
13Inhibition of Wnt activity improves peri-implantation development of somatic cell nuclear transfer embryos显示文摘Somatic cell nuclear transfer(SCNT) can reprogram differentiated somatic cells into totipotency.Although pre-implantation development of SCNT embryos has greatly improved,most SCNT blastocysts are still arrested at the peri-implantation stage,and the underlying mechanism remains elusive.Here,we develop a 3D in vitro culture system for SCNT peri-implantation embryos and discover that persistent Wnt signals block the naive-to-primed pluripotency transition of epiblasts with aberrant H3K27me3 occupancy,which in turn leads to defects in epiblast transformation events and subsequent implantation failure.Strikingly,manipulating Wnt signals can attenuate the pluripotency transition and H3K27me3 deposition defects in epiblasts and achieve up to a 9-fold increase in cloning efficiency.Finally,single-cell RNA-seq analysis reveals that Wnt inhibition marke dly enhances the lineage developmental trajectories of SCNT blastocysts during peri-implantation development.Overall,these findings reveal diminished potentials of SCNT blastocysts for lineage specification and validate a critical peri-implantation barrier for SCNT embryos.Yanhe Li Caihong Zheng Yingdong Liu Jincan He Qiang Zhang Yalin Zhang Xiaochen Kou Yanhong Zhao Kuisheng Liu Dandan Bai Yanping Jia Xiaoxiao Han Yifan Sheng Jiqing Yin Hong Wang Shuai Gao Wenqiang Liu Shaorong Gao 2023National Science Review2023,10,9:0
14Expression of vasa Gene in Development Process of Germ Cells in Male Rat显示文摘In order to explore the role of vasa gene in the development of germ cells after gonad differentiation in male rats,the expression of vasa mRNA and vasa protein in 17.5-day-old fetal rats and neonatal rats was detected by real-time fluorescent quantitative PCR and immunohistochemistry method.The results showed that the expression of vasa mRNA was detected in the testis tissue of 17.5-day-old fetal rats and neonatal rats,and the expression of vasa mRNA in testis of neonatal rats was high than that in fetal rats.The expression of vasa protein was detected in neonatal rats,but it was not found in fetal rats.In conclusion,vasa gene plays an important role in the development of germ cells.However,as a marker,it can only be used to label all kinds of germ cells after formation of prespermatogonia.He Zhiquan Gao Yingdong Chen Wei Lu Xiang 2016Animal Husbandry and Feed Science2016,8,3:0

16Reductive ionic liquid-mediated crystallization for enhanced photovoltaic performance of Sn-based perovskite solar cells显示文摘Tin(Sn)-based perovskite solar cells(PSCs)have recently made inspiring progress,and certified power conversion efficiency(PCE)has reached impressive value of 14.8%.However,it is still challenging to realize efficient and stable 3D Sn-based PSCs due to the fast crystallization and easy Sn^(2+)oxidation of Sn-based perovskite.Herein,we reported the utilization of a reductive ionic liquid,methylamine formate(MAFa),to drive the controlled crystallization process and suppress Sn^(2+)oxidation of FASnI_(3)perovskite film.The coordination of C=O and Sn^(2+)and the hydrogen bonding of N-H···I between the MAFa and FASnI_(3)precursors are shown to be responsible for retarding the crystallization of FASnI_(3)during film-forming process,which promotes the oriented growth and reduced defect traps of the film.Moreover,the strong reducibility of–CHO groups in Fa−suppresses the oxidation of Sn^(2+)in the film.As a result,MAFa-modified 3D PSCs device could reach champion PCE of up to 8.50%,which is enhanced by 26.11%compared to the control device with PCE of 6.74%.Most importantly,the MAFa-modified device shows much improved stability compared to the control device under same conditions without encapsulation.This work adds key building blocks for further boosting the PCE and stability of Sn-based PSCs.He Dong Chenxin Ran Wangyue Li Xin Liu Weiyin Gao Yingdong Xia Yonghua Chen Wei Huang 2022Science China Chemistry2022,65,10:0
