| 2 | Investigation on Precooling Effects of 4 K Stirling-Type Pulse Tube Cryocoolers显示文摘Stirling-type pulse tube cryocoolers(SPTCs)working at liquid-helium temperatures are appealing in space applications because of their promising advantages such as high reliability,compactness,etc.Worldwide efforts have been put in to develop SPTCs operating at liquid-helium temperatures especially with helium-4 as the working fluid.Staged structure is essential to reach such low temperatures.Generally,both the regenerator of the last section and the pulse tube together with the phase shifter are precooled by its upper stage or by external cold source to a low temperature of around 20 K.However,the precooling effects on the regenerator and the pulse tube are synthetic in previous studies,and their independent effects have not been studied clearly.In this manuscript,the precooling effects on the regenerator and on the pulse tube together with the phase shifter are tested independently on a unique-designed precooled SPTC.The tested precooling temperature is between 13.3 K and 22 K,and the no-load refrigeration temperature gets down to 3.6 K.Further analyses and numerical calculations have been carried out.It is found that the influence on the regenerator is remarkable,which is different from previous conclusions.It is also found that the precooling effects on the pulse tube are relatively weak because of the large pressure-induced enthalpy flow of a real gas working at the temperatures near to the critical point.Furthermore,the phase shifting capacity is analyzed with two cases and with both helium-4 and helium-3 as working fluids,and it keeps quite constant after optimizing the frequency and the precooling temperature for each case.The investigation on these independent effects will provide valid reference on the precooling mechanism study of SPTCs working down to liquid-helium temperatures. | CAO Qiang LI Zimu LUAN Mingkai SUN Zheng TANG Xiao LI Peng JIANG Zhenhua WEI Li | 2019 | Journal of Thermal Science2019，28，4： | 4 |
| 3 | Adsorption and Diffusion Behavior of Cl^- on Sputtering Fe–20Cr Nanocrystalline Thin Film in Acid Solution(pH = 2)显示文摘The adsorption and diffusion behavior of Cl^- on sputtering Fe-20 Cr nanocrystalline(NC) thin film compared with corresponding coarse crystalline(CC) alloy has been studied in HCl + NaCl solution(pH = 2,[Cl^-]=0.1 mol/L) by electrochemical techniques,X-ray photoelectron spectroscopy(XPS) and the firstprinciples calculations.The XPS results show that adsorption and diffusion of Cl^- in the passive film has been inhibited on NC thin film.Ultra-violet photoelectron spectroscopy(UPS) results show that the work function Φ_s of NC thin film(4.7 eV) is higher than that of CC alloy(4.5 eV).The theoretical calculations and valence electron structure analysis were used to understand the effect of nanocrystallization in this work. | Bin Zhang Li Liu Tianshu Li Ying Li Mingkai Lei Fuhui Wang | 2015 | Journal of Materials Science & Technology2015，31，12： | 2 |

| 5 | Theoretical assessment of hydrogen production and multicycle energy conversion via solar thermochemical cycle based on nonvolatile SnO2显示文摘A kind of solar thermochemical cycle based on methanothermal reduction of SnO2 is proposed for H2 and CO production. We find that the oxygen release capacity and thermodynamic driven force for methanothermal reduction of SnO2 are large, and suggest CH4 :SnO2 = 2:1 as the feasible reduction condition for achieving high purities of syngas and avoiding vaporization of produced Sn. Subsequently, the amount of H2 and energetic upgrade factors under different oxidation conditions are compared, in which excess water vapor is found beneficial for hydrogen production and fuel energetic upgradation. Moreover, the effect of incom plete recovery of SnO2 on the subsequent cycle is underscored and explained. After accounting for factors such as isothermal operation and cycle stability, CH4 :SnO2 = 2:1 and H2O:Sn = 4:1 are suggested for highest solar-to-fuel efficiency of 46.1% at nonisothermal condition, where the reduction and oxidation temperature are 1400 and 600 K, respectively. | Mingkai Fu Huajun Xu Haitao Ma Xin Li | 2019 | Journal of Energy Chemistry2019，28，11： | 1 |

| 11 | Non‐hemodynamic effects:Repurposing of nonselective beta‐blockers in cirrhosis?显示文摘To the Editor:Liver cirrhosis(LC),the end‐stage condition of chronic liver disease,results in>1,300,000 annual deaths worldwide.Meanwhile,the global incidence of decompensated cirrhosis is rising yearly.1 Following clinically significant portal hypertension(CSPH)in the late compensated stage of LC,as the disease progresses to the decompensated stage,ascites,gastroesophageal variceal bleeding,hepatic encephalopathy(HE),and other severe complications present.Nonselective beta‐blockers(NSBBs)have currently served as the first‐line therapy for primary and secondary prophylaxis of portal‐hypertensive gastrointestinal bleeding,as recommended by practice guidelines.2 Moreover,recent recommendations have extended the use of NSBBs to compensate LC patients with CSPH. | Yi Yang Mingkai Li Jinni Luo Hongsheng Yu Hong Tian Xing Wang | 2022 | Portal Hypertension & Cirrhosis2022，1，2： | 1 |

| 17 | A Critical Review of Real Gas Effects on the Regenerative Refrigerators显示文摘The regenerative refrigeration is an important reverse work-heat conversion cycle with a theoretical coefficient of performance(COP)identical to the Carnot efficiency.Practical regenerative refrigerators are capable of working down to 4 K and largely fulfill the refrigeration requirement of modern technologies in many fields,especially for space applications.However,the enthalpy flow associated with the pressure dependence,abbreviated as pressure-induced enthalpy flow,brought about by real gas effects degrades the theoretical COP of the refrigerator to below about 30% of the Carnot efficiency at the temperatures of below the critical point.This paper reviews the long history of exploring the real gas effects which dates back to the 1970 s and continues to now.Important explorations of uncovering the loss mechanism and reducing such losses are summarized.The theories that are in accordance with experimental results and simulation results are expounded.We further carry out analyses on the expansion components,including the pulse tube and the clearance gap.Several inferences are made in order to explore the long-lasting puzzles about real gas effects.It is emphasized that the underlying cause of the loss in the regenerator is an indirect effect of the real gas properties.Further study about carrying out a direct verification of the theory is proposed. | CAO Qiang LUAN Mingkai LI Peng WEI Li WU Yan | 2021 | Journal of Thermal Science2021，30，3： | 1 |

| 20 | High-dimensional zinc porphyrin nanoframeworks as efficient radiosensitizers for cervical cancer显示文摘Radiotherapy is widely used clinically, but the toxic and side effects of nonselective killing of high-energy radiation limit its application. Finding biocompatible materials to assemble radiotherapy sensitizers and studying their sensitization patterns are of great significance for the clinical application. Here, biocompatible zinc porphyrin was chosen as sub-unit to construct various dimensional coordination frameworks. By employing top-down approach, suitable nanoframeworks with various dimensional zinc porphyrin were synthesized as radiosensitizers. The experimental data showed that high-dimensional zinc porphyrin nanoframeworks exhibit higher X-ray response performance. | Fei Cai Kun Ye Mingkai Chen Yuan Tian Peicong Chen Hao Lin Tianfeng Chen Li Ma | 2023 | Chinese Chemical Letters2023，34，7： | 0 |
