| 1 | Indium doped CsPbI3 films for inorganic perovskite solar cells with efficiency exceeding 17%显示文摘In recent years,all-inorganic perovskite materials have set off a research boom owing to features,such as good thermal stability,suitable bandgap,and fascinating optical properties.However,the power conversion efficiency(PCE)and the ambient stability of all-inorganic perovskite solar cells still remain a challenge.Herein,we investigate the effect of the addition of InI3 into CsPbI3 film on the corresponding device.InI3 incorporation could retard the crystallization process and control the growth rate of CsPbI3 polycrystalline films,yielding a high quality film with large grains and few voids.The increment in electrostatic potential and the reduction of carrier recombination enabled the open-circuit voltage of fabricated perovskite solar cell to be increased from 0.89 to 0.99 V.The champion device delivered a power conversion efficiency of 17.09%,which is higher than 14.36%for the reference device.And the InI3-included solar cell without any encapsulation retained 77%of its original efficiency after 860 h aging at room temperature in N2 condition. | Xiaomei Li Kaili Wang Femi Lgbari Chong Dong Wenfan Yang Chang Ma Heng Ma Zhao-Kui Wang Liang-Sheng Liao | 2020 | Nano Research2020，13，8： | 4 |
| 2 | Climatology and seasonal variability of satellite-derived chlorophyll a around the Shandong Peninsula显示文摘The chlorophyll a(Chl a)is an important indicator of marine ecosystems.The spatiotemporal variation of the Chl a greatly aff ects the mariculture and marine ranching in coastal waters of the Shandong Peninsula.In the current study,the climatology and seasonal variability of surface Chl-a concentration around the Shandong Peninsula are investigated based on 16 years(December 2002-November 2018)of satellite observations.The results indicate that the annual mean Chl-a concentration is greater in the Bohai Sea than in the Yellow Sea and decreases from coastal waters to off shore waters.The highest Chl-a concentrations are found in Laizhou Bay(4.2-8.0 mg/m^(3)),Haizhou Bay(4.2-5.9 mg/m^(3))and the northeast coast of the Shandong Peninsula(4.4-5.0 mg/m^(3)),resulting from the combined eff ects of the intense riverine input and long residence time caused by the concave shape of the coastline.The seasonal Chl-a concentration shows a significant spatial variation.The Chl-a concentrations in these three subregions generally exhibit an annual maximum in August/September,due to the combined eff ects of sea surface temperature,river discharge and sea surface wind.In the southeast coast region,however,the Chl-a concentration is lowest throughout the year and reaches a maximum in February with a minimum in July,forced by the seasonal evolution of the Yellow Sea Cold Water and monsoon winds.The interannual Chl-a concentration trends vary among regions and seasons.There are significant increasing trends over a large area around Haizhou Bay from winter to summer,which are mainly caused by the rising sea surface temperature and eutrophication.In other coastal areas,the Chl-a concentration shows decreasing trends,which are clearest in summer and induced by the weakening land rainfall.This study highlights the differences in the Chl-a dynamics among regions around the Shandong Peninsula and is helpful for further studies of coupled physical-ecological-human interactions at multiple scales. | Xiukai SONG Yanzhen GU Fangguo ZHAI Peiliang LI Pengxia LIU Zizhou LIU Wenfan WU Yaozu CHEN Xiangyang JIANG Jianlong HE | 2021 | Journal of Oceanology and Limnology2021，39，4： | 3 |
| 3 | Faceted Kurdjumov-Sachs interface-induced slip continuity in the eutectic high-entropy alloy,AlCoCrFeNi_(2.1)显示文摘Recently,the eutectic high-entropy alloy(EHEA),AlCoCrFeNi_(2.1),can reach a good balance of strength and ductility.The dual-phase alloy exhibits a eutectic lamellar microstructure with large numbers of interfaces.However,the role of the interfaces in plastic deformation have not been revealed deeply.In the present work,the orientation relationship(OR)of the interfaces has been clarified as the Kurdjumov-Sachs(KS)interfaces presenting〈111〉_(B2) 〈110〉_(FCC)and {110} _(B2){111}_(FCC) independent of their morphologies.There exist three kinds of interfaces in the EHEA,namely,The dominating interface and the secondary interface are both non-slip planes and atomistic-scale faceted,facilitating the nucleation and slip transmission of the dislocations.The formation mechanism of the preferred interfaces is revealed using the atomistic geometrical analysis according to the criteria of the low interfacial energy based on the coincidence-site lattice(CSL)theory.In particular,the ductility of the dual-phase alloy originates from the KS interface-induced slip continuity across interfaces,which provides a high slip-transfer geometric factor.Moreover,the strengthening effect can be attributed to the interface resistance for the dislocation transmission due to the mismatches of the moduli and lattice parameters at the interfaces. | Ting Xiong Wenfan Yang Shijian Zheng Zhaorui Liu Yiping Lu Ruifeng Zhang Yangtao Zhou Xiaohong Shao Bo Zhang Jun Wang Fuxing Yin Peter K.Liaw Xiuliang Ma | 2021 | Journal of Materials Science & Technology2021，，6： | 2 |
| 4 | Atomic scale structure dominated FCC and B2 responses to He ion irradiation in eutectic high-entropy alloy AlCoCrFeNi_(2.1)显示文摘Radiation-tolerant materials are widely desired in nuclear reactors. High-entropy alloys(HEAs) exhibiting superior mechanical performance and swelling tolerance are being considered as next-generation nuclear structural materials. However, an understanding of HEAs irradiation tolerance at an atomic scale is still lacking. In this study, the atomic scale irradiation response of AlCoCrFeNi_(2.1), composed of face-centered cubic(FCC) phase and B2 phase, has been systematically investigated at 298 and 723 K. The bubble volume ratio of the B2 phase is much larger than that of the FCC phase under the same irradiation conditions, and hence, the FCC phase has superior swelling tolerance than the B2 phase. Also, order-disorder transformation occurred in both L12and B2 phases. The different irradiation responses between the FCC and B2 phases, depend firstly on composition and secondly on crystal structure. The higher compositional complexity and complicated atomic-level lattice environment of the FCC phase contribute to better radiation performance than B2 phase. The results pave a way for exploring radiation-tolerant structural high-entropy alloys. | Jingyu Pang Ting Xiong Wenfan Yang Hualong Ge Xiaodong Zheng Miao Song Hongwei Zhang Shijian Zheng | 2022 | Journal of Materials Science & Technology2022，，34： | 2 |
| 5 | Tunable strength of SiCf/β-Yb_(2)Si_(2)O_(7) interface for different requirements in SiCf/SiC CMC:Inspiration from model composite investigation显示文摘Model composites consisting of Si C fiber embedded inβ-Yb_(2)Si_(2)O_(7) matrix were processed by Spark Plasma Sintering method and the feasibility of tunable Si Cf/Yb_(2)Si_(2)O_(7) interface in Si C-based CMCs were estimated.Weak and strengthened Si Cf/Yb_(2)Si_(2)O_(7) interfaces were achieved by adjusting sintering temperatures.The indentation crack test and fiber push out experiments clearly demonstrated the different debonding mechanisms in the samples.Weak interfaces sintered at 1200 and 1250℃exhibited crack deflection at interface in indentation test.Their low debond energy at the interface,which were comparable to those of Py C or BN,satisfied the well-recognized interfacial debond and crack deflection criteria for CMCs.The interface was strengthened by atomic bonding in model composite sintered at 1450℃,leading to crack penetrating into Si C fiber and high debond energy.The strong interface may be promising in Si Cf/Si C CMC to withstand higher combustion temperature,because Yb_(2)Si_(2)O_(7) will provide plastic deformation capacity,which would serve as weak interphase for crack deflection and energy dissipation.Therefore,it is possible to design the capability of Si C_(f)/RE_(2)Si_(2)O_(7) interface for different requirements by adjusting interfacial strength or debond energy to reach optimal mechanical fuse mechanism in SiC_(f)/SiC CMC. | Xirui Lv Mengkun Yue Wenfan Yang Xue Feng Xiaoyan Li Yumin Wang Jiemin Wang Jie Zhang Jingyang Wang | 2021 | Journal of Materials Science & Technology2021，，8： | 2 |

| 11 | Digital Influencer's choice of product endorsement:A perspective of congruence显示文摘To infer product fitness information,consumers often consult digital influencers who exert effort to learn and evaluate product features and then propagate information to their followers.However,influencers'recommendations are not limited to products that exactly match their expertise,which may lead followers to unfollow them.This study investigates which product(high or low congruence)an influencer should endorse and how much endorsement effort should be exerted.Using a theoretical model,we obtain several interesting results.First,endorsing a low-congruence product can surprisingly benefit the influencer if the penalty per lost follower is moderate or if the influencer has sufficiently high efficiency in reducing the perception error of this product.Second,although the influencer has high expertise in the high-congruence product,she will lose more followers when endorsing it than when endorsing the low-congruence product if a particularly small or large proportion of her followers are potential consumers of the low-congruence product.Third,when the influencer endorses the low-congruence product,the number of new followers increases with the size of the influencer's follower base only when the follower base is small and a large proportion of followers are potential consumers of the low-congruence product.Interestingly,as the size of the follower base increases,the influencer always exerts more effort when endorsing the high-congruence product but will exert less effort in learning about the low-congruence product if a sufficiently small proportion of followers are potential consumers.Finally,after taking consumers'knowledge about product features into account,the main results still hold,and when considering the competition between influencers,we uncover the conditions under which both influencers will choose to endorse the high-congruence product. | Nan Feng Wenfan Zhao Haiyang Feng Minqiang Li Liang Xian | 2023 | Journal of Management Science and Engineering2023，8，3： | 0 |
| 12 | Normalized Wolfe-Powell-type local minimax method for finding multiple unstable solutions of nonlinear elliptic PDEs显示文摘The local minimax method(LMM)proposed by Li and Zhou(2001,2002)is an efficient method to solve nonlinear elliptic partial differential equations(PDEs)with certain variational structures for multiple solutions.The steepest descent direction and the Armijo-type step-size search rules are adopted in Li and Zhou(2002)and play a significant role in the performance and convergence analysis of traditional LMMs.In this paper,a new algorithm framework of the LMMs is established based on general descent directions and two normalized(strong)Wolfe-Powell-type step-size search rules.The corresponding algorithm framework,named the normalized Wolfe-Powell-type LMM(NWP-LMM),is introduced with its feasibility and global convergence rigorously justified for general descent directions.As a special case,the global convergence of the NWP-LMM combined with the preconditioned steepest descent(PSD)directions is also verified.Consequently,it extends the framework of traditional LMMs.In addition,conjugate-gradient-type(CG-type)descent directions are utilized to speed up the NWP-LMM.Finally,extensive numerical results for several semilinear elliptic PDEs are reported to profile their multiple unstable solutions and compared with different algorithms in the LMM’s family to indicate the effectiveness and robustness of our algorithms.In practice,the NWP-LMM combined with the CG-type direction performs much better than its known LMM companions. | Wei Liu Ziqing Xie Wenfan Yi | 2023 | Science China Mathematics2023，66，10： | 0 |
| 13 | Facile Surface Engineering of NiCo_(2)O_(4) to Boost Propane Oxidation Activity显示文摘Spinel oxide(NiCo_(2)O_(4))has demonstrated great potential to replace noble metal catalysts for the oxidation reaction of air pollutants.To further boost the oxidation ability of such catalysts,in this study,a facile surface-engineering strategy wherein NiCo_(2)O_(4) was treated with different alkali solvents was developed.The obtained catalyst(NiCo_(2)O_(4)-OH)showed a higher surface alkalinity and more surface defects compared to the pristine spinel oxide,including enhanced structural distortion as well as promoted oxygen vacancies.The propane oxidation ability of NiCo_(2)O_(4)-OH was greatly enhanced,with a propane conversion rate that was approximately 6.4 times higher than that of pristine NiCo_(2)O_(4) at a reaction temperature 193℃.This work sets a valuable paradigm for the surface modulation of spinel oxide via alkali treatment to ensure a high-performance oxidation catalyst. | Yang Jialei Wang Fengyi Lei Yang Zhang Mingchao Sun Shiqiang Xu Wenfan Ke Jiaxiang Wu Haojie Li Xingyun Qi Jian | 2024 | China Petroleum Processing & Petrochemical Technology2024，26，1： | 0 |
| 14 | Reforming Chinese Teacher Education:Findings from Training Program of Multiple-Subject Elementary School Teachers in Rural Northwestern China显示文摘This research analyzed the lack of education practical competency and training curriculum in teacher education,redefined two core concepts:the educational practical competency and the multiple-subject elementary school teacher.Based on these analysis and definition,this study divided the educational practical competency into three level:basic competency,key competency,and external competency.According to the education practice theory,this study divides the multiple-subject elementary school teachers’educational practical competency into three parts:the practice to learning the practical wisdom,the practice to communicate with others,and the practice to reflect oneself.Through these review,this study designed three rounds of action research to find a practical way to promote students’educational practical competency,combined with the action research,the classroom observation,classroom interaction,and focused group interview.This cyclic openness process is renovated every round and reach the developing goal,at last finds some reformations of teacher education in rural Northwestern China. | Qingyun Wu Mi Zhou Hui Zhou Wenfan Yan | 2020 | US-China Education Review(A)2020，10，3： | 0 |
| 15 | Fission yeast cells mix parental mitochondria in a progressive manner during meiosis显示文摘Mitochondria in many fungi are inherited uniparentally during meiosis. It has remained unclear whether parental mitochondria in the fission yeast Schizosaccharomyces pombe are inherited uniparentally or biparentally. Here, we assessed the mixing of parental mitochondria carefully by live-cell microscopy and developed an algorithm to determine the degree of mitochondrial mixing in a quantitative manner. We found that parental mitochondria in fission yeast cells were mixed progressively as meiosis progressed. Moreover, we established that mitochondrial fission and the size of the conjugation neck are the limiting factors in restricting the mixing of parental mitochondria. We further employed a combination of quantitative polymerase chain reaction, fluorescent live-cell microscopy, and transmission electron microscopy approaches to examine the mitochondrial inheritance of progeny cells derived from a cross between wild-type and Rho0 (mitochondrial DNA absent) cells. The results show that all progeny cells of the cross carry mitochondrial DNA. Hence, our data support the model in which parental mitochondria in the fission yeast S. pombe are inherited biparentally during meiosis. | Daqiang Wu Yongkang Chu Wenfan Wei Ling Liu Chuanhai Fu | 2022 | Journal of Molecular Cell Biology2022，14，11： | 0 |
| 16 | Efficacy and safety of activating blood circulation and removing blood stasis of Traditional Chinese Medicine for managing renal fibrosis in patients with chronic kidney disease:a systematic review and Meta-analysis显示文摘OBJECTIVE:To evaluate the efficacy and safety of activating blood circulation and removing blood stasis in terms of Traditional Chinese Medicine(TCM) for managing renal fibrosis(RF) in patients with chronic kidney disease(CKD).METHODS:We searched randomized controlled trials(RCTs) from eight databases.RESULTS:Sixteen eligible studies with 1,356 participants were included in this study.Compared to treatment with Western Medicine(WM) alone,the combined treatment with activating blood circulation and removing blood stasis in terms of TCM(ARTCM) and WM to manage RF in patients with CKD significantly ameliorated type Ⅳ collagen(C-Ⅳ)(SMD:-2.17,95% CI:3.01 to-1.34),type Ⅲ procollagen(PC-Ⅲ)(SMD:-1.08,95% CI:-1.64 to-0.53),laminin(LN)(SMD:-1.28,95% CI:-1.65 to-0.90),transforming growth factor β 1(TGF-β1)(SMD:-0.65,95% CI:-1.18 to-0.12),serum creatinine(Scr)(SMD:-1.36,95% CI:-1.85 to-0.87),blood urea nitrogen(BUN)(MD:-1.51,95% CI:-2.59 to-0.43),and 24 h urine protein(24h Upro)(SMD:-1.23;95% CI:-1.96 to-0.50).The level of hyaluronic acid(HA) was similar in both types of treatment(SMD:-0.74,95% CI:-1.91 to 0.44).The subgroup analysis showed that the duration of 8 weeks might affect the concentration of C-Ⅳ,PC-Ⅲ,and LN(P < 0.05).The effectiveness of the longer duration to C-Ⅳ,PC-Ⅲ,and LN was not certain.However,the result should be interpreted in care.The safety of the treatment using ARTCM and WM could not be evaluated because a few studies had reported adverse effects.The results of the Meta-analysis were not stable enough.There was publication bias for the reports on Scr(P = 0.001),C-Ⅳ(P = 0.001),PC-Ⅲ(P = 0.026),and LN(P = 0.030) and no publication bias for the reports on BUN(P = 0.293).The quality of evidence varied from low to very low.CONCLUSIONS:The combined treatment using ARTCM and WM to manage RF in patients with CKD has some advantages over treatment with WM alone.High-quality RCTs need to be conducted for the strong support. | LUO Xin XIE Jing HUANG Li GAN Wenfan CHEN Ming | 2023 | Journal of Traditional Chinese Medicine2023，43，3： | 0 |
| 17 | Preliminary Study on Optimized Conditions for Dry-cultivated Rice Seedling Planting显示文摘The effects of soil moisture content,pot seedling buried depth,and pot seedling height on the survival rate and growth of dry planted seedlings were researched by field experiment. The results showed that the seedling survival rate and growth were enhanced with the increase of soil moisture content after pot seedling transplanting,but there was no significant difference in the survival rate and growth of seedlings with 85% and 100% of soil moisture content. Pot seedling buried depth was one of the important factors affecting the survival rate,and when the pot seedlings were buried 2 cm deep,the seedlings showed high survival rate and excellent growth. Under the same condition of soil moisture content and buried depth,seedlings with pot seedling height of 15 cm had the best survival rate and growth. Therefore,the optimized conditions for dry-cultivated rice seedling planting were soil moisture content of 85%,pot seedling buried depth of 2 cm,and pot seedling height of 15 cm. | Shurong XIN Xiuying YU Zhengtao YANG Shichun JIAN Dongfeng ZHENG Wenfan BIAN Hongtao SHAN Chang ai ZHANG | 2018 | Agricultural Biotechnology2018，7，5： | 0 |
| 18 | Effects of Different Planting Densities on the Yield of Rice Developed from Seedlings Dry Raised in Plug Trays显示文摘[Objectives]This study was conducted to investigate the effects of different planting densities on rice tillering dynamics and yield. [Methods]The effects of different planting densities on rice yield were studied based on seedlings dry raised in plug trays. [Results]Planting density had obvious effects on tillering dynamics,number of panicles per unit area,number of grains per panicle and rice yield under the condition of seedlings dry raised in plug trays. Comprehensive analysis showed that the row spacing × hill spacing = 25 cm × 14 cm,that is,the planting density of 2. 85 × 10~5 hills/hm^2,achieved the highest yield,at 9 960 kg/hm^2. [Conclusions]This study provides a scientific basis for optimizing rice cultivation techniques and achieving high yield and high efficiency in rice production. | Shurong XIN Xiuying YU Wenfan BIAN Qinglei ZHAO Li YAO Bing GUO Xibo WU Hongtao SHAN Ye TIAN Baogang ZHU Zhengtao YANG | 2020 | Agricultural Biotechnology2020，9，3： | 0 |
