| 1 | Synergistically Directed Assembly of Aromatic Stacks Based Metal-Organic Frameworks by Donor-Acceptor and Coordination Interactions显示文摘A synergistically directed assembly approach to distinctive metal-organic frameworks utilizing both donor-acceptor (D-A) interaction from aromatic systems and coordination interactions is presented.Based on such an approach,the coronene-tpt (tpt =2,4,6-tri(4-pyridyl)-1,3,5-triazine) stacks based coronene-MOF-1-4 have been successfully fabricated.Their structural discrepancies with coroneneabsent control products,1'-4',illustrate clearly the significance of coronene-tpt based D-A interactions in these architectures.All these coronene-MOFs contain varied coronene-tpt stacks as organic secondary building blocks (SBUs),which are closely interrelated with the coordination based framework structures.Moreover,porous coronene-MOF-1 and-2 exhibit high physicochemical stability and significant light hydrocarbons storage and separation performances. | Xi Wang Ying Zhang Ze Chang Hui Huang Xiao-Ting Liu Jialiang Xu Xian-He Bu | 2019 | Chinese Journal of Chemistry2019,37,9: | 11 |
| 2 | Apolipoprotein E, amyloid-beta, and neuroinflammation in Alzheimer's disease显示文摘Alzheimer's disease(AD) is characterized by the accumulation and deposition of amyloid-beta(Aβ) peptides in the brain. Neuroinflammation occurs in the AD brain and plays a critical role in the neurodegenerative pathology. Particularly, Aβ evokes an inflammatory response that leads to synaptic dysfunction, neuronal death, and neurodegeneration. Apolipoprotein E(ApoE) proteins are involved in cholesterol transport, Aβ binding and clearance, and synaptic functions in the brain. The ApoE4 isoform is a key risk factor for AD, while the ApoE2 isoform has a neuroprotective effect. However, studies have reached different conclusions about the roles of the isoforms; some show that both ApoE3 and ApoE4 have anti-infl ammatory effects, while others show that ApoE4 causes a predisposition to inflammation or promotes an inflammatory response following lipopolysaccharide treatment. These discrepancies may result from the differences in models, cell types, experimental conditions, and inflammatory stimuli used. Further, little was known about the role of ApoE isoforms in the Aβ-induced inflammatory response and in the neuroinflammation of AD. Our recent work showed that ApoE isoforms differentially regulate and modify the Aβ-induced infl ammatory response in neural cells, with ApoE2 suppressing and ApoE4 promoting the response. In this article, we review the roles, mechanisms, and interrelations among Aβ, ApoE, and neuroinfl ammation in AD. | Evan Dorey Nina Chang Qing Yan Liu Ze Yang Wandong Zhang | 2014 | Neuroscience Bulletin2014,30,2: | 9 |
| 3 | Xinglou Chengqi Decoction improves neurological function in experimental stroke mice as evidenced by gut microbiota analysis and network pharmacology显示文摘The current study was designed to explore the brain protection mechanism of Xinglou Chengqi Decoction(XCD)based on gut microbiota analysis and network pharmacology. A transient middle cerebral artery occlusion(MCAO) model of mice was established, followed by behavioral evaluation, TTC and TUNEL staining. Additionally, to investigate the effects of gut microbiota on neurological function after stroke, C57BL/6 mice were treated with anti-biotic cocktails 14 days prior to ischemic stroke(IS) to deplete the gut microbiota. High-throughput 16S rDNA gene sequencing, metabonomics technique, and flow multifactor technology were used to analyze bacterial communities, SCFAs and inflammatory cytokines respectively. Finally, as a supplement, network pharmacology and molecular docking were applied to fully explore the multicomponent-multitarget-multichannel mechanism of XCD in treating IS, implicated in ADME screening, target identification, network analysis, functional annotation, and pathway enrichment analysis.We found that XCD effectively improved neurological function, relieved cerebral infarction and decreased the neuronal apoptosis.Moreover, XCD promoted the release of anti-inflammatory factor like IL-10, while down-regulating pro-inflammatory factors such as TNF-α, IL-17A, and IL-22. Furthermore, XCD significantly increased the levels of short chain fatty acids(SCFAs), especially butyric acid. The mechanism might be related to the regulation of SCFAs-producing bacteria like Verrucomicrobia and Akkermansia, and bacteria that regulate inflammation like Paraprevotella, Roseburia, Streptophyta and Enterococcu. Finally, in the network pharmacological analysis, 51 active compounds in XCD and 44 intersection targets of IS and XCD were selected. As a validation, components in XCD docked well with key targets. It was obviously that biological processes were mainly involved in the regulation of apoptotic process, inflammatory response, response to fatty acid, and regulation of establishment of endothelial barrier in GO enrichment. XCD can improve neurological function in experimental stroke mice, partly due to the regulation of gut microbiota. Besises, XCD has the characteristic of 'multi-component, multi-target and multi-channel' in the treatment of IS revealed by network pharmacology and molecular docking. | GAO Qiang HAN Zhen-Yun TIAN Dan-Feng LIU Gan-Lu WANG Zhen-Yi LIN Jing-Feng CHANG Ze ZHANG Dan-Dan XIE Ying-Zhen SUN Yi-Kun YAO Xing-Wei MA Da-Yong | 2021 | Chinese Journal of Natural Medicines2021,19,12: | 6 |
| 4 | Syntheses, structures and magnetic properties of three Co(Ⅱ)coordination architectures based on a flexible multidentate carboxylate ligand and different N-donor ligands显示文摘Three new cobalt complexes,{[Co5(tci)2(bimb)3(3-O)2(H2O)2]·3DMF·4H2O}n(1),{[Co3(tci)2(bib)]·2DMF·2H2O}n(2)and{[Co(Htci)(bpea)0.5]·H2O}n(3)(H3tci=tris(2-carboxyethyl)isocyanurate,bimb=4,4′-bis(imidazol-1-yl)biphenyl,bib=1,4-bis(imidazol-1-yl)benzene,bpea=1,2-bis(4-pyridyl)ethane,DMF=N,N′-dimethylformamide),have been successfully synthesized through the assembly of Co(II)ions,H3tci and different N-donor ligands,respectively.All complexes were structurally characterized by single crystal X-ray diffraction,elemental analyses,IR spectra,thermogravimetric(TG)analyses and X-ray powder diffraction(XRPD).Complex 1 exhibits a 3D three-fold parallel interpenetrated 3D→3D structure with(65·8)CdSO4topology.Complex 2 is built from[Co3(2-Ocarboxyl)2(CO2)4]clusters and linear bib ligands,displaying a two-fold parallel interpenetrated(3,8)-connected(43)2(46·618·84)topology,while complex 3 is a 3D pillar-layered structure involving an infinite–Co–(2-Ocarboxyl)(CO2)–Co–chain.The diverse structures of the three complexes indicate that the skeletons of different N-donor ligands play an important role in the assembly of such different frameworks.In addition,magnetic investigation indicates that besides spin-orbit coupling of Co(II)ions,there exist antiferromagnetic exchange interactions in Co5and Co3clusters of 1 and 2,respectively. | TIAN Dan LIU SuiJun ZHANG DaShuai CHANG Ze HU TongLiang BU XianHe | 2013 | Science China Chemistry2013,56,12: | 5 |
| 5 | Effects of ultrasound on the desulfurization performance of hot coal gas over Zn-Mn-Cu supported on semi-coke sorbent prepared by high-pressure impregnation method显示文摘Zn-Mn-Cu/SC(U) sorbent was hydrothermally synthesized by ultrasound-assisted high-pressure impregnation method with semi-coke(SC)as support and the mixed solution of zinc nitrate,manganese nitrate and copper nitrate as active component precursors.The desulfurization performances of hot coal gas on the prepared sorbent at a mid-temperature of 500°C were tested in fixed-bed reactor.Morphology and pore structure of the prepared sorbent were also characterized by TEM,N2adsorption/desorption isotherms and XRD.For comparison,the sorbent of Zn-Mn-Cu/SC prepared by conventional high-pressure impregnation was also evaluated and characterized in order to study the effects of ultrasound treatment.Zn-Mn-Cu/SC(U) sorbent prepared by high-pressure impregnation under ultrasound-assisted condition showed a better desulfurization performance than Zn-Mn-Cu/SC.It could remove H2 S from 1000×10-6m3/m3 to 0.1×10-6m3/m3 at 500°C and maintained for 12.5 h with the sulfur capacity of 7.74%,in which both the breakthrough time and sulfur capacity were about 32% and 51% higher than those of Zn-Mn-Cu/SC sorbent.The introduction of ultrasound during high-pressure impregnation process greatly improved the morphology and pore structure of the sorbent.The ultrasonic treatment made particle size of active components smaller and made them more evenly disperse on semi-coke support,which provided more opportunities to contact with H2S in coal-based gases.However,there were no any difference in compositions and existing forms of active components on the Zn-Mn-Cu/SC and Zn-Mn-Cu/SC(U) sorbents. | Xiaoyang Zhang Xianrong Zheng Peng Han Ze Liu Liping Chang | 2015 | Journal of Energy Chemistry2015,24,3: | 4 |
| 6 | First experimental constraints on WIMP couplings in the effective field theory framework from CDEX显示文摘We present weakly interacting massive particles(WIMPs) search results performed using two approaches of effective field theory from the China Dark Matter Experiment(CDEX), based on the data from both CDEX-1B and CDEX-10 stages. In the nonrelativistic effective field theory approach, both time-integrated and annual modulation analyses were used to set new limits for the coupling of WIMP-nucleon effective operators at 90% confidence level(C.L.) and improve over the current bounds in the low mχregion. In the chiral effective field theory approach, data from CDEX-10 were used to set an upper limit on WIMP-pion coupling at 90% C.L. We for the first time extended the limit to the m_(χ)<6 GeV/c^(2) region. | Yi Wang Zhi Zeng Qian Yue LiTao Yang KeJun Kang YuanJing Li Mehment Agartioglu HaiPeng An JianPing Chang JingHan Chen YunHua Chen JianPing Cheng Cheng Yi Chiang WenHan Dai Zhi Deng ChangHao Fang XinPing Geng Hui Gong QiuJu Guo XuYuan Guo HongJian He Li He ShengMing He JinWei Hu TuChen Huang HanXiong Huang HaiTao Jia LiPing Jia Xi Jiang HauBin Li JianMin Li Jin Li MingXuan Li RenMingJie Li Xia Li YuLan Li Bin Liao FongKay Lin ShinTed Lin ShuKui Liu YanDong Liu Yu Liu YuanYuan Liu ZhongZhi Liu Hao Ma YuCai Mao QiYuan Nie JinHua Ning Hui Pan NingChun Qi Jie Ren XiChao Ruan ChangSong Shang Vivek Sharma Ze She Lakhwinder Singh Monoj Kumar Singh TianXi Sun ChangJian Tang WeiYou Tang Yang Tian GuangFu Wang Li Wang Qing Wang Yu Chen Wang YunXiang Wang Zhen Wang Henry Tsz-King Wong ShiYong Wu YuCheng Wu HaoYang Xing Yin Xu Tao Xue YuLu Yan Nan Yi ChunXu Yu HaiJun Yu JianFeng Yue Ming Zeng BingTao Zhang Lei Zhang FengShou Zhang ZhenYu Zhang KangKang Zhao MingGang Zhao JiFang Zhou ZuYing Zhou JingJun Zhu | 2021 | Science China(Physics,Mechanics & Astronomy)2021,64,8: | 3 |

| 9 | Verification of SEU resistance in 65 nm high-performance SRAM with dual DICE interleaving and EDAC mitigation strategies显示文摘A dual double interlocked storage cell(DICE)interleaving layout static random-access memory(SRAM)is designed and manufactured based on 65 nm bulk complementary metal oxide semiconductor technology.The single event upset(SEU)cross sections of this memory are obtained via heavy ion irradiation with a linear energy transfer(LET)value ranging from 1.7 to 83.4 MeV/(mg/cm^(2)).Experimental results show that the upset threshold(LETth)of a 4 KB block is approximately 6 MeV/(mg/cm^(2)),which is much better than that of a standard unhardened SRAM with an identical technology node.A 1 KB block has a higher LETth of 25 MeV/(mg/cm^(2))owing to the use of the error detection and correction(EDAC)code.For a Ta ion irradiation test with the highest LET value(83.4 MeV/(mg/cm^(2))),the benefit of the EDAC code is reduced significantly because the multi-bit upset proportion in the SEU is increased remarkably.Compared with normal incident ions,the memory exhibits a higher SEU sensitivity in the tilt angle irradiation test.Moreover,the SEU cross section indicates a significant dependence on the data pattern.When comprehensively considering HSPICE simulation results and the sensitive area distributions of the DICE cell,it is shown that the data pattern dependence is primarily associated with the arrangement of sensitive transistor pairs in the layout.Finally,some suggestions are provided to further improve the radiation resistance of the memory.By implementing a particular design at the layout level,the SEU tolerance of the memory is improved significantly at a low area cost.Therefore,the designed 65 nm SRAM is suitable for electronic systems operating in serious radiation environments. | Ze He Shi-Wei Zhao Tian-Qi Liu Chang Cai Xiao-Yu Yan Shuai Gao Yu-Zhu Liu Jie Liu | 2021 | Nuclear Science and Techniques2021,32,12: | 2 |

| 12 | Dynamic Analysis of Axial Magnetic Forces for DVD Spindle Motors显示文摘The axial magnetic force, induced by the complicated flux linkage distribution from rotor magnet and stator slotted, is constructed by different relative heights and calculated by 3D finite element method (FEM) to analyze the dynamic characteristics for a DVD spindle motor. The axial magnetic force is designed to provide an axial stiffness and govern the natural frequency of the dynamic performance. According to the simulation results and experimental measurements, the dynamic behaviors are significantly improved with a variation of relative height of rotor magnet and stator slotted on a DVD spindle motor. | Chung-Ping Liu (Department of Electrical Engineering, Yuan Ze University, Chungli 320, Taiwan-China) Yeong-Hwa Chang and Tsung-Kun Lin (Department of Electrical Engineering, Chung Cheng Institute of Technology, Taoyuan 335, Taiwan-China) Der-Ray Huang, T | 2000 | Journal of Materials Science & Technology2000,16,2: | 1 |
| 13 | Heavy ion‑induced MCUs in 28nm SRAM‑based FPGAs:upset proportions,classifications,and pattern shapes显示文摘For modern scaling devices,multiple cell upsets(MCUs)have become a major threat to high-reliability field-programmable gate array(FPGA)-based systems.Thus,both performing the worst-case irradiation tests to provide the actual MCU response of devices and proposing an effective MCU distinction method are urgently needed.In this study,high-and medium-energy heavy-ion irradiations for the configuration random-access memory of 28 nm FPGAs are performed.An MCU extraction method supported by theoretical predictions is proposed to study the MCU sizes,shapes,and frequencies in detail.Based on the extraction method,the different percentages,and orientations of the large MCUs in both the azimuth and zenith directions determine the worse irradiation response of the FPGAs.The extracted largest 9-bit MCUs indicate that high-energy heavy ions can induce more severe failures than medium-energy ones.The results show that both the use of high-energy heavy ions during MCU evaluations and effective protection for the application of high-density 28 nm FPGAs in space are extremely necessary. | Shuai Gao Xin‑Yu Li Shi‑Wei Zhao Ze He Bing Ye Li Cai You‑Mei Sun Guo‑Qing Xiao Chang Cai Jie Liu | 2022 | Nuclear Science and Techniques2022,33,12: | 1 |

| 16 | Identification of broad neutralizing antibodies against Omicron subvariants from COVID-19 convalescents and vaccine recipients显示文摘Dear Editor,Omicron(B.1.1.529)was designated a variant of concern(VOC)on November 26,2021(Callaway,2021),and its subvariants BA.1,BA.2,and BA.3 emerged and circulated almost simultaneously(Desingu et al.,2022).BA.2 was more efficient in transmission and quickly overtook BA.1 to become the variant most frequently detected worldwide(Yamasoba et al.,2022a).Compared to the prototype SARS-CoV-2 spike protein(S),the BA.1 and BA.2 spike proteins harbor more than 30 mutations,of which 21 are identical between the two subvariants,while the BA.3 spike differs from BA.1 and BA.2 by 3 mutations in the receptor binding domain(RBD)(Fig.1A).More recently,BA.4 and BA.5(hereafter BA.4/5)emerged,sharing the same spike sequence and containing four additional mutations,Del69–70,L452R,F486V,and R493Q,compared with BA.2.BA.4/5 were detected first in South Africa and evolved independently of BA.2;they have spread widely and replaced BA.2 as the predominant VOC(Gruell et al.,2022b;Tegally et al.,2022).In addition,BA.2.75,derived from the BA.2 subvariant,harbors nine additional mutations in the spike protein compared with BA.2(Fig.1A).BA.4/5 and BA.2.75 have led to the continuous emergence of novel Omicron subvariants,including BF.7 and BQ.1.These new subvariants may be driving waves of pandemics. | Jun Chen Jing Yang Fangfang Chang Yabin Hu Qian Wu Shishan Teng Yongchen Liu Jian Zhang Rongzhang He Bo Liu Xingyu Zheng Ze Liu Yanxi Peng Zhenhua Xie Yuanfang Zhang Rui Lu Dong Pan You Wang Liting Peng Wenpei Liu Yi-Ping Li Xiaowang Qu | 2023 | Virologica Sinica2023,38,2: | 0 |
| 17 | Safety and immunogenicity of a mosaic vaccine booster against Omicron and other SARS-CoV-2 variants:a randomized phase 2 trial显示文摘An ongoing randomized,double-blind,controlled phase 2 trial was conducted to evaluate the safety and immunogenicity of a mosaic-type recombinant vaccine candidate,named NVSI-06-09,as a booster dose in subjects aged 18 years and older from the United Arab Emirates(UAE),who had administered two or three doses of inactivated vaccine BBIBP-CorV at least 6 months prior to enrollment.The participants were randomly assigned with 1:1 to receive a booster dose of NVSI-06-09 or BBIBP-CorV.The primary outcomes were immunogenicity and safety against severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)Omicron variant,and the exploratory outcome was cross-immunogenicity against other circulating strains.Between May 25 and 30,2022,516 adults received booster vaccination with 260 in NVSI-06-09 group and 256 in BBIBP-CorV group.Interim results showed a similar safety profile between two booster groups,with low incidence of adverse reactions of grade 1 or 2.For immunogenicity,by day 14 post-booster,the fold rises in neutralizing antibody geometric mean titers(GMTs)from baseline elicited by NVSI-06-09 were remarkably higher than those by BBIBP-CorV against the prototype strain(19.67 vs 4.47-fold),Omicron BA.1.1(42.35 vs 3.78-fold),BA.2(25.09 vs 2.91-fold),BA.4(22.42 vs 2.69-fold),and BA.5 variants(27.06 vs 4.73-fold).Similarly,the neutralizing GMTs boosted by NVSI-06-09 against Beta and Delta variants were also 6.60-fold and 7.17-fold higher than those by BBIBP-CorV.Our findings indicated that a booster dose of NVSI-06-09 was well-tolerated and elicited broad-spectrum neutralizing responses against divergent SARS-CoV-2 variants,including Omicron and its sub-lineages. | Nawal Al Kaabi Yun Kai Yang Yu Liang Ke Xu Xue Feng Zhang Yun Kang Yu Qin Jin Jun Wei Hou Jing Zhang Tian Yang Salah Hussein Mohamed Saif ElDein Ze Hua Lei Hao Zhang Shuai Shao Zhao Ming Liu Ning Liu Xiang Zheng Ji Guo Su Sen Sen Yang Xiangfeng Cong Yao Tan Wenwen Lei Xue Jun Gao Zhiwei Jiang Hui Wang Meng Li Hanadi Mekki Mekki Walid Zaher Sally Mahmoud Xue Zhang Chang Qu Dan Ying Liu Jing Zhang Mengjie Yang Islam Eltantawy Peng Xiao Fu Jie Shen Jin Juan Wu Zi Bo Han Li Fang Du Fang Tang Shi Chen Zhi Jing Ma Fan Zheng Ya Nan Hou Xin Yu Li Xin Li Zhao Nian Wang Jin Liang Yin Xiao Yan Mao Jin Zhang Liang Qu Yun Tao Zhang Xiao Ming Yang Guizhen Wu Qi Ming Li | 2023 | Signal Transduction and Targeted Therapy2023,8,2: | 0 |
| 18 | Differences in MBUs induced by high-energy and medium-energy heavy ions in 28 nm FPGAs显示文摘Multiple-bit upsets(MBUs)have become a threat to modern advanced field-programmable gate arrays(FPGAs)applications in radiation environments.Hence,many investigations have been conducted using mediumenergy heavy ions to study the effects of MBU radiation.However,high-energy heavy ions(HEHIs)greatly affect the size and percentage of MBUs because their ionizationtrack structures differ from those of medium-energy heavy ions.In this study,the different impacts of high-energy and medium-energy heavy ions on MBUs in 28 nm FPGAs as well as their mechanisms are thoroughly investigated.With the Geant4 calculation,more serious energy effects of HEHIs on MBU scales were successfully demonstrated.In addition,we identified worse MBU responses resulting from lowered voltages.The MBU orientation effect was observed in the radiation of different dimensions.The broadened ionization tracks for tilted tests in different dimensions could result in different MBU sizes.The results also revealed that the ionization tracks of tilted HEHIs have more severe impacts on the MBU scales than mediumenergy heavy ions with much higher linear energy transfer.Therefore,comprehensive radiation with HEHIs is indispensable for effective hardened designs to apply highdensity 28 nm FPGAs in deep space exploration. | Shuai Gao Jin-Hu Yang Bing Ye Chang Cai Ze He Jie Liu Tian-Qi Liu Xiao-Yu Yan You-Mei Sun Guo-Qing Xiao | 2022 | Nuclear Science and Techniques2022,33,9: | 0 |
| 19 | In situ atomic-scale observation of size-dependent (de) potassiation and reversible phase transformation in tetragonal FeSe anodes显示文摘Potassium-ion batteries(PIBs)are considered promising alternatives to lithium-ion batteries owing to cost-effective potassium resources and a suitable redox potential of-2.93 V(vs.-3.04 V for Li+/Li).However,the exploration of appro-priate electrode materials with the correct size for reversibly accommodating large K+ions presents a significant challenge.In addition,the reaction mecha-nisms and origins of enhanced performance remain elusive.Here,tetragonal FeSe nanoflakes of different sizes are designed to serve as an anode for PIBs,and their live and atomic-scale potassiation/depotassiation mechanisms are revealed for the first time through in situ high-resolution transmission electron micros-copy.We found that FeSe undergoes two distinct structural evolutions,sequen-tially characterized by intercalation and conversion reactions,and the initial intercalation behavior is size-dependent.Apparent expansion induced by the intercalation of K+ions is observed in small-sized FeSe nanoflakes,whereas unexpected cracks are formed along the direction of ionic diffusion in large-sized nanoflakes.The significant stress generation and crack extension originating from the combined effect of mechanical and electrochemical interactions are elucidated by geometric phase analysis and finite-element analysis.Despite the different intercalation behaviors,the formed products of Fe and K_(2)Se after full potassiation can be converted back into the original FeSe phase upon depotassiation.In particular,small-sized nanoflakes exhibit better cycling perfor-mance with well-maintained structural integrity.This article presents the first successful demonstration of atomic-scale visualization that can reveal size-dependent potassiation dynamics.Moreover,it provides valuable guidelines for optimizing the dimensions of electrode materials for advanced PIBs. | Ran Cai Lixia Bao Wenqi Zhang Weiwei Xia Chunhao Sun Weikang Dong Xiaoxue Chang Ze Hua Ruiwen Shao Toshio Fukuda Zhefei Sun Haodong Liu Qiaobao Zhang Feng Xu Lixin Dong | 2023 | InfoMat2023,5,1: | 0 |
| 20 | Surface passivation and hole extraction:Bifunctional interfacial engineering toward high-performance all-inorganic CsPbIBr2 perovskite solar cells with efficiency exceeding 12%显示文摘All-inorganic CsPbIBr2perovskite solar cells(PSCs)have attracted considerable research attention in recent years due to their excellent thermal stability.However,their power conversion efficiencies(PCEs)are relatively low and still far below the theoretical limit.Here,we report the use of an organic dye molecule(namely VG1-C8)as a bifunctional interlayer between perovskite and the hole-transport layer in CsPbIBr2PSCs.Combined experimental and theoretical calculation results disclose that the multiple Lewis base sites in VG1-C8 can effectively passivate the trap states on the perovskite films.Meanwhile,theπ-conjugated dye molecule significantly accelerates the hole extraction from the perovskite absorber as evidenced by the photoluminescence analysis.Consequently,the VG1-C8 treatment simultaneously boosts the photovoltage and photocurrent density values from 1.26 V and 10.80 mA cm^(-2) to 1.31 V and 12.44 m A cm^(-2),respectively.This leads to a significant enhancement of PCE from 9.20%to12.10%under one sun irradiation(AM 1.5G).To our knowledge,this is the record efficiency reported so far for CsPbIBr_(2) PSCs.Thus,the present work demonstrates an effective interfacial passivation strategy for the development of highly efficient PSCs. | Qi Liu Junming Qiu Xianchang Yan Yuemeng Fei Yue Qiang Qingyan Chang Yi Wei Xiaoliang Zhang Wenming Tian Shengye Jin Ze Yu Licheng Sun | 2022 | Journal of Energy Chemistry2022,31,11: | 0 |
