| 1 | Ultra-small platinum nanoparticles segregated by nickle sites for efficient ORR and HER processes显示文摘In the electrochemical process,Pt nanoparticles(NPs)in Pt-based catalysts usually agglomerate due to Oswald ripening or lack of restraint,ultimately resulting in reduction of the active sites and catalytic efficiency.How to uniformly disperse and firmly fix Pt NPs on carbon matrix with suitable particle size for catalysis is still a big challenge.Herein,to prevent the agglomeration and shedding of Pt NPs,Ni species is introduced and are evenly dispersed in the surface of carbon matrix in the form of Ni-N-C active sites(Ni ZIF-NC).The Ni sites can be used to anchor Pt NPs,and then effectively limit the further growth and agglomeration of Pt NPs during the reaction process.Compared with commercial Pt/C catalyst,Pt@Ni ZIF-NC,with ultralow Pt loading(7 wt%)and ideal particle size(2.3 nm),not only increases the active center,but also promotes the catalysis kinetics,greatly improving the ORR and HER catalytic activity.Under acidic conditions,its half-wave potential(0.902 V)is superior to commercial Pt/C(0.861 V),and the mass activity(0.38 A per mg Pt)at 0.9 V is 4.7 times that of Pt/C(0.08 A per mg Pt).Besides,it also shows outstanding HER performance.At 20 and 30 mV,its mass activity is even 2 and 6 times that of Pt/C,respectively.Whether it is under ORR or HER conditions,it still shows excellent durability.These undoubtedly indicate the realization of dual-functional catalysts with low-Pt and high-efficiency properties. | Lvhan Liang Huihui jin Huang Zhou Bingshuai Liu Chenxi Hu Ding Chen Jiawei Zhu Zhe Wang Hai-Wen Li Suli Liu Daping He Shichun Mu | 2022 | Journal of Energy Chemistry2022,31,2: | 2 |
| 2 | Tunable Atomic-Scale Steps and Cavities Break Both Stability and Activity Limits of CoO_(x) Nanosheets to Catalyze Oxygen Evolution显示文摘A highly active interface can enhance the catalytic efficiency of catalysts toward the oxygen evolution reaction(OER).However,accurately tuning their atomic interface configurations of defects with sufficient activity and stability remains a grand challenge.Herein,we report on breaking the activity and stability limits of CoO_(x) nanosheets in the OER process by constructing copious high-energy atomic steps and cavities,in which S or Ce atoms simultaneously replace O or Co atoms from CoO_(x),thus achieving high-energy atomic interface Ce,O-Co_(3)S_(4) nanosheets.By combining in situ characterization and density functional theory calculations,it is shown that the unique orbital coupling between Ce-4f,O(S)-2p,and Co-3d causes it to be closer to the Fermi level,leading to faster charge transfer capability.More importantly,the novel structure breaks the stability limit of cobalt sulfide with planar defects,which gives high catalytic activity and stability in 0.1 M KOH solutions,better than commercial RuO_(2) and IrO_(2) noble metal catalysts.As expected,Ce,O-Co_(3)S_(4) possesses much better turnover frequency activity(0.064 s^(-1))at an overpotential of 300 mV,which is ~7 times larger than that of Ce-CoO_(x)(0.009 s^(-1)).Our work presents a new perspective of designing catalysts with atomically dispersed orbital electronic coupling defects toward efficient OER electrocatalysis. | Min Yu Xueqin Mu Weitao Meng Ziyue Chen Yu Tong Yu Ge Shiyuan Pang Shengjie Li Suli Liu Shichun Mu | 2023 | Renewables2023,1,4: | 1 |

| 4 | The importance of proleptic branch traits in biomass production of poplar in high-density plantations显示文摘Branch phenotypic traits determine tree crown architecture,which in turn governs leaf display,light interception,and biomass production.Sylleptic and proleptic branches are the obviously different branch phenotypes in the poplar crown.Many studies have focused on the influence of sylleptic branch numbers(SBN)on biomass production,but the research on the influence of proleptic branch phenotypes was only a few.To explore the relationship between proleptic branch traits and biomass generation production in a high-density poplar plantation,we investigated the branch phenotypic traits of three poplar genotypes,all of which have high survival rates in forests(>95%)and significantly different crown architecture and biomass performance in the high-density plantations(1667 stems ha−1).The plantation site was established in 2007.A terrestrial laser scanner was used to measure branch characteristics such as length,angle of origin and termination,and azi-muth angle.A hierarchical cluster analysis performed on branch characteristics showed that SBN,crown depth,and proleptic branch curvature(PBC)were clustered with bio-mass production and leaf area index(LAI).Among all of the monitored traits,PBC played the second most important role in biomass production after SBN and was significantly correlated with SBN,LAI,and biomass production.The positive correlation between PBC and SBN indicated that a larger PBC was associated with more sylleptic branches within the monitored genotypes planted in the high-density plantation,providing greater leaf area and biomass produc-tion.The results of this study will improve the identification of high-production poplar varieties for cultivation in high-density plantations for biofuel production. | Changjun Ding Ningning Wang Qinjun Huang Weixi Zhang Juan Huang Suli Yan Boyi Chen Dejun Liang Yufeng Dong Yingbai Shen Xiaohua Su | 2022 | Journal of Forestry Research2022,33,2: | 1 |

| 6 | High Fe^(LS)(C)electrochemical activity of an iron hexacyanoferrate cathode boosts superior sodium ion storage显示文摘Sodium iron hexacyanoferrate(FeHCF)is one of the most promising cathode materials for sodium-ion batteries(SIBs)due to its low cost theoretical capacity.However,the low electrochemical activity of Fe^(LS)(C)in FeHCF drags down its practical capacity and potential plateau.Herein,FeHCF with high Fe^(LS)(C)electrochemical activity(C-FeHCF)is synthesized via a facile citric acid-assisted solvothermal method.As the cathode of SIBs,C-FeHCF shows superior cycling stability(ca.87.3%capacity retention for 1000 cycles at 10 C)and outstanding rate performance(ca.68.5%capacity retention at 50 C).Importantly,the contribution of Fe^(LS)(C)to the whole capacity was quantitatively analyzed via combining dQ/dV and discharge curve for the first time,and the index reaches 44.53%for C-FeHCF,close to the theoretical value.In-situ X-ray diffraction proves the structure stability of C-FeHCF during charge-discharge process,ensuring its superior cycling performance.Furthermore,the application feasibility of the C-FeHCF cathode in quasi-solid SIBs is also evaluated.The quasi-solid SIBs with the C-FeHCF cathode exhibit excellent electrochemical performance,delivering an initial discharge capacity of 106.5 mAh g^(−1) at 5 C and high capacity retention of 89.8%over 1200 cycles.This work opens new insights into the design and development of advanced cathode materials for SIBs and the beyond. | Junhong Guo Fan Feng Shiqiang Zhao Zhenhai Shi Rui Wang Meng Yang Fangfang Chen Suli Chen Zi-Feng Ma Tianxi Liu | 2023 | Carbon Energy2023,5,5: | 1 |

| 9 | Gi-protein-coupledβ_(1)-adrenergic receptor:re-understanding the selectivity ofβ_(1)-adrenergic receptor to G protein显示文摘β_(1)-adrenergic receptor(β_(1)-AR),a member in the family of G-protein-coupled receptors,is a transmembrane receptor of great significance in the heart.Physiologically,catecholamines activateβ_(1)-AR to initiate a positive chronotropic,inotropic,and dromotropic change.It is believed thatβ_(1)-AR couples to Gs protein and transmits the signal through second messenger cAMP.However,increasing research shows thatβ_(1)-AR can also bind with Gi protein in addition to Gs.Whenβ_(1)-AR-Gi is biasedly activated,cardioprotective effects are introduced by the activated cGMP-protein kinase G(PKG)pathway and the transactivation of epidermal growth factor receptor(EGFR)pathway.The discovery ofβ_(1)-AR-Gi signaling makes us reconsider the selectivity of G protein with regard toβ_(1)-AR,which also provides new ideas for the treatment of heart diseases.This review summarizes the discovery ofβ_(1)-AR-Gi pathway,including the evidence that supportsβ_(1)-AR’s capability to couple Gi,details of the transduction process and functions of theβ_(1)-AR-Gi signaling pathway. | Hao Chen Suli Zhang Ruiqi Hou Huirong Liu | 2022 | Acta Biochimica et Biophysica Sinica2022,54,8: | 0 |
| 10 | Single-atom Fe Embedded Co_(3)S_(4) for Efficient Electrocatalytic Oxygen Evolution Reaction显示文摘Constructing atomically dispersed active sites with densely exposed and dispersed double metal-Sx catalytic sites for favorable OER catalytic activity remains rare and challenging.Herein,we design and construct a Fe_(1)S_(x)@Co_(3)S_(4) electrocatalyst with Fe single atoms epitaxially confined in Co_(3)S_(4) nanosheets for catalyzing the sluggish alkaline oxygen evolution reaction(OER).Consequently,in ultralow concentration alkaline solutions(0.1 mol/L KOH),such a catalyst is highly active and robust for OER with low overpotentials of 300 and 333 mV at current densities of 10 and 30 mA/cm^(2),respectively,accompanying long-term stability without significant degradation even for 350 h.In addition,Fe_(1)S_(x)@Co_(3)S_(4) shows a turnover frequency(TOF)value of 0.18 s−1,nearly three times that of Co_(3)S_(4)(0.07 s−1),suggesting the higher atomic utilization of Fe single atoms.Mössbauer and in-situ Raman spectra confirm that the OER activity of Fe_(1)S_(x)@Co_(3)S_(4) origins from a thin catalytic layer of Co(Fe)OOH that interacts with trace-level Fe species in the electrolyte,creating dynamically stable active sites.Combined with experimental characterizations,it suggests that the most active S-coordinated dual-metal site configurations are 2S-bridged(Fe-Co)S4,in which Co-S and Fe-S moieties are shared with two S atoms,which can strongly regulate the adsorption energy of reaction intermediates,accelerating the OER reaction kinetics. | QI Yuxue LI Tingting HU Yajie XIANG Jiahong SHAO Wenqian CHEN Wenhua MU Xueqin LIU Suli CHEN Changyun YU Min MU Shichun | 2022 | Chemical Research in Chinese Universities2022,38,5: | 0 |
| 11 | Atomically dispersed dual Fe centers on nitrogen-doped bamboo-like carbon nanotubes for efficient oxygen reduction显示文摘Interfacial atomic configuration between dual-metal active species and nitrogen-carbon substrates is of great importance for improving the intrinsic activity of catalysts toward oxygen reduction reaction(ORR).Thus,from the atomic-scale engineering we develop a high intrinsic activity ORR catalyst in terms of incorporating atomically dispersed dual Fe centers(single Fe atoms and ultra-small Fe atomic clusters)into bamboo-like N-doped carbon nanotubes.Benefiting from atomically dispersed dual-Fe centers on the atomic interface of Fe-Nx/carbon nanotubes,the fabricated dual Fe centers catalyst exhibits an extremely high ORR activity(E_(onset)=1.006 V;E_(1/2)=0.90 V),beyond state-of-the-art Pt/C.Remarkably,this catalyst also shows a superior kinetic current density of 19.690 mA·cm^(−2),which is 7 times that of state-of-the-art Pt/C.Additionally,based on the excellent catalyst,the primary Zn-air battery reveals a high power density up to 137 mW·cm^(−2) and sufficient potential cycling stability(at least 25 h).Undoubtedly,given the unique structure–activity relationship of dual-Fe active species and metal-nitrogen-carbon substrates,the catalyst will show great prospects in highly efficient electrochemical energy conversion devices. | Ligang Ma Junlin Li Zhiwei Zhang Hao Yang Xueqin Mu Xiangyao Gu Huihui Jin Ding Chen Senlin Yan Suli Liu Shichun Mu | 2022 | Nano Research2022,15,3: | 0 |
| 12 | Thermodynamics fundamentals and energy efciency for the separation and high‑valued utilization of Fischer–Tropsch heavy oil显示文摘The development trend of Fischer–Tropsch(F–T)technology is to develop high value-added products.The separation of linearα-olefns with low cost is an efective method.Nevertheless,the lack of thermodynamic data and the huge energy consumption are the two main problems restricting the development of the separation process.The thermodynamic data of the key components(1-dodecene and n-dodecane)in the F–T product were measured.The Wilson binary interaction parameters of the key components were obtained.Next,one traditional distillation column sequence and two dividing wall column(DWC)sequences were designed to separate the F–T heavy oil to obtain narrow fractions with diferent carbon numbers.Then,the obtained fractions of C10 and C12 were simulated to obtain 1-decene and 1-dodecene,respectively.There was a traditional distillation and a diferential pressure thermal coupling distillation process.When separating 95.0%purity 1-decene and 1-octene,the direct DWC process and diferential pressure thermal coupled distillation are an excellent combination,which can reduce the energy by 33.1%(i.e.,11,286 kW)and total annual cost by 15.9%(i.e.,3.96×10^(6)$)compared with traditional distillation. | Zongchao Liu Hong Li Suli Liu Jiuzhou Chen Zisheng Zhang Xingang Li Angui Zhang Wei Yuan Xin Gao | 2022 | International Journal of Coal Science & Technology2022,9,4: | 0 |
| 13 | CeO2 quantum dots doped Ni-Co hydroxide nanosheets for ultrahigh energy density asymmetric supercapacitors显示文摘By integrating the merits of lanthanide elements and quantum dots,we firstly design CeO2 quantum dots doped Ni-Co hydroxide nanosheet via a controllable synthetic strategy,which exhibits a large specific capacitance(1370.7 F/g at 1.0 A/g) and a good cyclic stability(90.6% retention after 4000 cycles).Moreover,we assemble an aqueous asymmetric supercapacitor with the obtained material,which has an extremely high energy density(108.9 Wh/kg at 378 W/kg) and outstanding cycle stability(retaining88.1% capacitance at 2.0 A/g after 4000 cycles). | Huiyu Duan Tong Wang Xinyi Wu Ziyun Su Jing Zhuang Suli Liu Rongmei Zhu Changyun Chen Huan Pang | 2020 | Chinese Chemical Letters2020,31,9: | 0 |
| 14 | A New Position Calibration Method for MUSER Images显示文摘The Mingantu Spectral Radioheliograph(MUSER),a new generation of solar dedicated radio imagingspectroscopic telescope,has realized high-time,high-angular,and high-frequency resolution imaging of the Sun over an ultra-broadband frequency range.Each pair of MUSER antennas measures the complex visibility in the aperture plane for each integration time and frequency channel.The corresponding radio image for each integration time and frequency channel is then obtained by inverse Fourier transformation of the visibility data.However,the phase of the complex visibility is severely corrupted by instrumental and propagation effects.Therefore,robust calibration procedures are vital in order to obtain high-fidelity radio images.While there are many calibration techniques available—e.g.,using redundant baselines,observing standard cosmic sources,or fitting the solar disk—to correct the visibility data for the above-mentioned phase errors,MUSER is configured with non-redundant baselines and the solar disk structure cannot always be exploited.Therefore it is desirable to develop alternative calibration methods in addition to these available techniques whenever appropriate for MUSER to obtain reliable radio images.In the case where a point-like calibration source contains an unknown position error,we have for the first time derived a mathematical model to describe the problem and proposed an optimization method to calibrate this unknown error by studying the offset of the positions of radio images over a certain period of the time interval.Simulation experiments and actual observational data analyses indicate that this method is valid and feasible.For MUSER’s practical data the calibrated position errors are within the spatial angular resolution of the instrument.This calibration method can also be used in other situations for radio aperture synthesis observations. | Zhichao Zhou Yihua Yan Linjie Chen Wei Wang Suli Ma | 2022 | Research in Astronomy and Astrophysics2022,22,10: | 0 |
| 15 | Rationally designing electrolyte additives for highly improving cyclability of LiNi_(0.5)Mn_(1.5)O_(4)/Graphite cells显示文摘High voltage is necessary for high energy lithium-ion batteries but difficult to achieve because of the highly deteriorated cyclability of the batteries.A novel strategy is developed to extend cyclability of a high voltage lithium-ion battery,LiNi_(0.5)Mn_(1.5)O_(4)/Graphite(LNMO/Graphite)cell,which emphasizes a rational design of an electrolyte additive that can effectively construct protective interphases on anode and cathode and highly eliminate the effect of hydrogen fluoride(HF).5-Trifluoromethylpyridine-trime thyl lithium borate(LTFMP-TMB),is synthesized,featuring with multi-functionalities.Its anion TFMPTMB-tends to be enriched on cathode and can be preferentially oxidized yielding TMB and radical TFMP-.Both TMB and radical TFMP can combine HF and thus eliminate the detrimental effect of HF on cathode,while the TMB dragged on cathode thus takes a preferential oxidation and constructs a protective cathode interphase.On the other hand,LTFMP-TMB is preferentially reduced on anode and constructs a protective anode interphase.Consequently,a small amount of LTFMP-TMB(0.2%)in 1.0 M LiPF6in EC/DEC/EMC(3/2/5,wt%)results in a highly improved cyclability of LNMO/Graphite cell,with the capacity retention enhanced from 52%to 80%after 150 cycles at 0.5 C between 3.5 and 4.8 V.The as-developed strategy provides a model of designing electrolyte additives for improving cyclability of high voltage batteries. | Zhiyong Xia Kuan Zhou Xiaoyan Lin Zhangyating Xie Qiurong Chen Xiaoqing Li Jie Cai Suli Li Hai Wang Mengqing Xu Weishan Li | 2024 | Journal of Energy Chemistry2024,91,4: | 0 |
| 16 | Afterglow Carbon Dots:From Fundamentals to Applications显示文摘The ability of carbon dots(CDs)to emit afterglow emission in addition to fluorescence in response to UV-to-visible excitation allows them to be a new class of luminescent materials.When compared with traditional organic or inorganic afterglow materials,CDs have a set of advantages,including small size,ease of synthesis,and absence of highly toxic metal ions.In addition,high dependence of their afterglow color output on temperature,excitation wavelength,and aggregation degrees adds remarkable flexibility in the creation of multimode luminescence of CDs without the need for changing their intrinsic attributes.These characteristics make CDs particularly attractive in the fields of sensing,anticounterfeiting,and data encryption.In this review,we first describe the general attributes of afterglow CDs and their fundamental afterglow mechanism.We then highlight recent strategic advances in the generation or activation of the afterglow luminescence of CDs.Considerable emphasis is placed on the summarization of their emergent afterglow properties in response to external stimulation.We further highlight the emerging applications of afterglow CDs on the basis of their unique optical features and present the key challenges needed to be addressed before the realization of their full practical utility. | Chenxi Peng Xue Chen Meiling Chen Shenci Lu Yu Wang Suli Wu Xiaowang Liu Wei Huang | 2021 | Research2021,,1: | 0 |
| 17 | Identification of genome-wide nucleotide sites associated with mammalian virulence in influenza A viruses显示文摘The virulence of influenza viruses is a complex multigenic trait.Previous studies about the virulence determinants of influenza viruses mainly focused on amino acid sites,ignoring the influence of nucleotide mutations.In this study,we collected>200 viral strains from 21 subtypes of influenza A viruses with virulence in mammals and obtained over 100 mammalian virulence-related nucleotide sites across the genome by computational analysis.Fifty of these nucleotide sites only experienced synonymous mutations.Experiments showed that synonymous mutations in three high-scoring nucleotide sites,i.e.,PB1–2031,PB1–633,and PB1–720,enhanced the pathogenicity of the influenza A(H1N1)viruses in mice.Besides,machine-learning models with accepted accuracy for predicting mammalian virulence of influenza A viruses were built.Overall,this study highlighted the importance of nucleotide mutations,especially synonymous mutations in viral virulence,and provided rapid methods for evaluating the virulence of influenza A viruses.It could be helpful for early warning of newly emerging influenza A viruses. | Peng Yousong Zhu Wenfei Feng Zhaomin Zhu Zhaozhong Zhang Zheng Chen Yongkun Liu Suli Wu Aiping Wang Dayan Shu Yuelong Jiang Taijiao | 2020 | Biosafety and Health2020,2,1: | 0 |
