| 1 | A high-quality Actinidia chinensis(kiwifruit)genome显示文摘Actinidia chinensis(kiwifruit)is a perennial horticultural crop species of the Actinidiaceae family with high nutritional and economic value.Two versions of the A.chinensis genomes have been previously assembled,based mainly on relatively short reads.Here,we report an improved chromosome-level reference genome of A.chinensis(v3.0),based mainly on PacBio long reads and Hi-C data.The high-quality assembled genome is 653 Mb long,with 0.76%heterozygosity.At least 43%of the genome consists of repetitive sequences,and the most abundant long terminal repeats were further identified and account for 23.38%of our novel genome.It has clear improvements in contiguity,accuracy,and gene annotation over the two previous versions and contains 40,464 annotated protein-coding genes,of which 94.41%are functionally annotated.Moreover,further analyses of genetic collinearity revealed that the kiwifruit genome has undergone two whole-genome duplications:one affecting all Ericales families near the K-T extinction event and a recent genus-specific duplication.The reference genome presented here will be highly useful for further molecular elucidation of diverse traits and for the breeding of this horticultural crop,as well as evolutionary studies with related taxa. | Haolin Wu Tao Ma Minghui Kang Fandi Ai Junlin Zhang Guanyong Dong Jianquan Liu | 2019 | Horticulture Research2019，6，1： | 10 |
| 2 | A chromosome-scale genome assembly of Isatis indigotica,an important medicinal plant used in traditional Chinese medicine显示文摘Isatis indigotica(2n=14)is an important medicinal plant in China.Its dried leaves and roots(called Isatidis Folium and Isatidis Radix,respectively)are broadly used in traditional Chinese medicine for curing diseases caused by bacteria and viruses such as influenza and viral pneumonia.Various classes of compounds isolated from this species have been identified as effective ingredients.Previous studies based on transcriptomes revealed only a few candidate genes for the biosynthesis of these active compounds in this medicinal plant.Here,we report a high-quality chromosome-scale genome assembly of I.indigotica with a total size of 293.88 Mb and scaffold N50=36.16 Mb using single-molecule real-time long reads and high-throughput chromosome conformation capture techniques.We annotated 30,323 highconfidence protein-coding genes.Based on homolog searching and functional annotations,we identified many candidate genes involved in the biosynthesis of main active components such as indoles,terpenoids,and phenylpropanoids.In addition,we found that some key enzyme-coding gene families related to the biosynthesis of these components were expanded due to tandem duplications,which likely drove the production of these major active compounds and explained why I.indigotica has excellent antibacterial and antiviral activities.Our results highlighted the importance of genome sequencing in identifying candidate genes for metabolite synthesis in medicinal plants. | Minghui Kang Haolin Wu Qiao Yang Li Huang Quanjun Hu Tao Ma Zaiyun Li Jianquan Liu | 2020 | Horticulture Research2020，7，1： | 9 |
| 3 | NiPS_(3)quantum sheets modified nitrogen-doped mesoporous carbon with boosted bifunctional oxygen electrocatalytic performance显示文摘Electrocatalysts for oxygen reduction reactions(ORR)and oxygen evolution reactions(OER)are highly crucial and challenging toward the energy storage and conversion technologies such as fuel cells,metal-air batteries and water electrolysis.To replace noble-metal based catalysts and boost catalytic performance of carbon-based materials,we initially develop the nickel,phospho rus,sulfur and nitrogen co-modified mesoporous carbon(NiPS_(3)@NMC)as a bifunctional oxygen electrocatalyst.The perfo rmance for ORR(half-wave potential at 0.90 V)and OER(10 mA cm^(-2)at 1.48 V)surpasses those of Pt/C coupled with IrO_(2)catalysts and most of the non-precious metal based bifunctional electrocatalysts reported in related literature.Moreover,the electrochemical durability is also confirmed by accelerated durability tests(ADTs)and long-term chronoamperometry(CA)tests.We demonstrated that the interfacial effect between NiPS_(3)quantum sheets(QS s)and NMC substrates by thermal activation contributed to the enhanced oxygen electrode bifunctionality with more active sites,due to the electrons-donating from nickel,phosphorus and sulfur elements and relatively enriched pyridinic type N.Such excellent overall performance highlights the potential application of NiPS3 QSs and NMC composites as the materials on energy conversion and storage. | Kai Huang Yuyang Xu Yanpeng Song Ruyue Wanga Hehe Wei Yuanzheng Long Ming Lei Haolin Tang Jiangang Guo Hui Wu | 2021 | Journal of Materials Science & Technology2021，，6： | 7 |
| 4 | Rational design of hierarchically porous Fe-N-doped carbon as efficient electrocatalyst for oxygen reduction reaction and Zn-air batteries显示文摘The rational design and construction of hierarchically porous nanostructure for oxygen reduction reaction (ORR) electrocatalysts is crucial to facilitate the exposure of accessible active sites and promote the mass/electron transfer under the gas-solid-liquid triple-phase condition. Herein, an ingenious method through the pyrolysis of creative polyvinylimidazole coordination with Zn/Fe salt precursors is developed to fabricate hierarchically porous Fe-N-doped carbon framework as efficient ORR electrocatalyst. The volatilization of Zn species combined with the nanoscale Kirkendall effect of Fe dopants during the pyrolysis build the hierarchical micro-, meso-, and macroporous nanostructure with a high specific surface area (1,586 m^(2)·g^(−1)), which provide sufficient exposed active sites and multiscale mass/charge transport channels. The optimized electrocatalyst exhibits superior ORR activity and robust stability in both alkaline and acidic electrolytes. The Zn-air battery fabricated by such attractive electrocatalyst as air cathode displays a higher peak power density than that of Pt/C-based Zn-air battery, suggesting the great potential of this electrocatalyst for Zn-air batteries. | Zihan Meng Neng Chen Shichang Cai Jiawei Wu Rui Wang Tian Tian Haolin Tang | 2021 | Nano Research2021，14，12： | 4 |
| 5 | 2D nanomaterials for tissue engineering application显示文摘Recently,tissue engineering has developed into a powerful tool for repairing and reconstructing damaged tissues and organs.Tissue engineering scaffolds play a vital role in tissue engineering,as they not only provide structural support for targeted cells but also serve as templates that guide tissue regeneration and control the tissue structure.Over the past few years,owing to unique physicochemical properties and excellent biocompatibility,various types of two-dimensional(2D)nanomaterials have been developed as candidates for the construction of tissue engineering scaffolds,enabling remarkable achievements in bone repair,wound healing,neural regeneration,and cardiac tissue engineering.These efforts have significantly advanced the development of tissue engineering.In this review,we summarize the latest advancements in the application of 2D nanomaterials in tissue engineering.First,each typical 2D nanomaterial is introduced briefly,followed by a detailed description of its applications in tissue engineering.Finally,the existing challenges and prospects for the future of the application of 2D nanomaterials in tissue engineering are discussed. | Jingyang Zhang Haolin Chen Meng Zhao Guiting Liu Jun Wu | 2020 | Nano Research2020，13，8： | 3 |
| 6 | Exponential time differencing based efficient SC-PML for RCS simulation显示文摘To efficiently simulate and calculate the radar cross section(RCS) related electromagnetic problems by employing the finite-difference time-domain(FDTD) algorithm, an efficient stretched coordinate perfectly matched layer(ESC-PML) based upon the exponential time differencing(ETD) method is proposed.The proposed implementation can not only reduce the number of auxiliary variables in the SC-PML regions but also maintain the ability of the original SC-PML in terms of the absorbing performance. Compared with the other existed algorithms, the ETDFDTD method shows the least memory consumption resulting in the computational efficiency. The effectiveness and efficiency of the proposed ESC-PML scheme is verified through the RCS relevant problems including the perfect E conductor(PEC) sphere model and the patch antenna model. The results indicate that the proposed scheme has the advantages of the ETD-FDTD method and ESC-PML scheme in terms of high computational efficiency and considerable computational accuracy. | NIU Liqiang XIE Yongjun JIANG Haolin WU Peiyu | 2020 | Journal of Systems Engineering and Electronics2020，31，4： | 3 |
| 7 | A framework for the fusion of visual and tactile modalities for improving robot perception显示文摘Robots should ideally perceive objects using human-like multi-modal sensing such as vision, tactile feedback, smell, and hearing. However, the features presentations are different for each modal sensor. Moreover,the extracted feature methods for each modal are not the same. Some modal features such as vision, which presents a spatial property, are static while features such as tactile feedback, which presents temporal pattern,are dynamic. It is difficult to fuse these data at the feature level for robot perception. In this study, we propose a framework for the fusion of visual and tactile modal features, which includes the extraction of features, feature vector normalization and generation based on bag-of-system(BoS), and coding by robust multi-modal joint sparse representation(RM-JSR) and classification, thereby enabling robot perception to solve the problem of diverse modal data fusion at the feature level. Finally, comparative experiments are carried out to demonstrate the performance of this framework. | Wenchang ZHANG Fuchun SUN Hang WU Haolin YANG | 2017 | Science China(Information Sciences)2017，60，1： | 2 |
| 8 | Redox responsive nanoparticle encapsulating black phosphorus quantum dots for cancer theranostics显示文摘Effective cancer treatment puts high demands for cancer theranostics.For cancer diagnostics,optical coherence tomography(OCT)technology(including photothermal optical coherence tomography(PT-OCT))has been widely investigated since it induces changes in optical phase transitions in tissue through environmental changes(such as temperature change for PT-OCT).In this report,redox responsive nanoparticle encapsulating black phosphorus quantum dots was developed as a robust PT-OCT agent.Briefly,black phosphorus quantum dots(BPQDs)are incorporated into cysteine-based poly-(disulfide amide)(Cys-PDSA)to form stable and biodegradable nanoagent.The excellent photothermal feature allows BPQD/Cys-PDSA nanoparticles(NPs)as a novel contrast agent for high-resolution PT-OCT bioimaging.The Cys-PDSA can rapidly respond to glutathione and effectively release BPQDs and drugs in vitro and in vivo.And the obtained NPs exhibit excellent near-infrared(NIR)photothermal transduction efficiency and drug delivery capacity that can serve as novel therapeutic platform,with very low chemo drug dosage and side effects.Both of the polymer and BPQD are degradable,indicating this platform is a rare PT-OCT agent that is completely biodegradable.Overall,our research highlights a biodegradable and biocompatible black phosphorus-based nanoagent for both cancer diagnosis and therapy. | Haolin Chen Zhiming Liu Bo Wei Jun Huang Xinru You Jingyang Zhang Zhiling Yuan Zhilie Tang Zhouyi Guo Jun Wu | 2021 | Bioactive Materials2021，6，3： | 1 |
| 9 | Pervasive hybridization during evolutionary radiation of Rhododendron subgenus Hymenanthes in mountains of southwest China显示文摘Radiations are especially important for generating species biodiversity in mountainous ecosystems.The contribution of hybridization to such radiations has rarely been examined.Here,we use extensive genomic data to test whether hybridization was involved in evolutionary radiation within Rhododendron subgenus Hymenanthes,whose members show strong geographic isolation in the mountains of southwest China.We sequenced genomes for 143 species of this subgenus and 93 species of four other subgenera,and found that Hymenanthes was monophyletic and radiated during the late Oligocene to middle Miocene.Widespread hybridization events were inferred within and between the identified clades and subclades.This suggests that hybridization occurred both early and late during diversification of subgenus Hymenan thes,although the extent to which hybridization,speciation through mixing-isolation-mixing or hybrid speciation,accelerated the diversification needs further exploration.Cycles of isolation and contact in such and other montane ecosystems may have together promoted species radiation through hybridization between diverging populations and species.Similar radiation processes may apply to other montane floras in this region and elsewhere. | Yazhen Ma Xingxing Mao Ji Wang Lei Zhang Yuanzhong Jiang Yuying Geng Tao Ma Liming Cai Shuangquan Huang Pete Hollingsworth Kangshan Mao Minghui Kang Yiling Li Wenlu Yang Haolin Wu Yang Chen Charles C.Davis Nawal Shrestha Richard H.Ree Zhenxiang Xi Quanjun Hu Richard I.Milne Jianquan Liu | 2022 | National Science Review2022，9，12： | 1 |
| 10 | Unsplit-field higher-order nearly PML for arbitrary media in EM simulation显示文摘An unsplit-field higher order nearly perfectly matched layer(NPML)based on the auxiliary differential equation approach is introduced in three-dimensional finite-difference timedomain lattices.The proposed scheme has the advantage of both the NPML scheme and the higher order concept in terms of the improved absorbing performance and considerable computational efficiency.By incorporating with the generalized material independent concept,the proposed implementation is indepen dent of the material’s type.Thus,it has the advantages of terminating arbitrary media without changing the updated equations in the PML regions.Its effectiveness and efficiency is further demonstrated through numerical examples. | JIANG Haolin XIE Yongjun WU Peiyu ZHANG Jianfeng NIU Liqiang | 2021 | Journal of Systems Engineering and Electronics2021，32，1： | 1 |
| 11 | Approximate CN scheme and its open region problems for metamaterial rotational symmetric simulation显示文摘In order to simulate metamaterial rotational symmetric open region problems,unconditionally stable perfectly match layer(PML)implementation is proposed in the body of revolution(BOR)finite-difference time-domain(FDTD)lattice.More precisely,the proposed algorithm is implemented by the Crank-Nicolson(CN)Douglas-Gunn(DG)procedure for BOR metamaterial simulation.The constitutive relationship of metamaterial can be expressed by the Drude model and calculated by the piecewise linear recursive convolution(PLRC)approach.The effectiveness including absorption,efficiency,and accuracy is demonstrated through the numerical example.It can be concluded that the proposed implementation is to take the advantages of the CNDG-PML procedure,PLRC approach,and BORFDTD algorithm in terms of considerable accuracy,enhanced absorption and remarkable efficiency.Meanwhile,it can be demonstrated that the proposed scheme can maintain its unconditional stability when the time step exceeds the CourantFriedrichs-Levy(CFL)condition. | WU Peiyu YU Han HU Yenan XIE Yongjun JIANG Haolin | 2022 | Journal of Systems Engineering and Electronics2022，33，6： | 1 |
| 12 | An artificial interphase enables stable PVDF-based solid-state Li metal batteries显示文摘Composite polymer electrolytes(CPEs)have attracted much attention for high energy density solid-state lithium-metal batteries owing to their flexibility,low cost,and easy scale-up.However,the unstable Li/CPE interface is always challengeable for the practical utilization of CPEs.Herein,a polymer interlayer containing K+prepared by ultraviolet(UV)-curing precursor solution is coated on Li surface to stabilize the interface between poly(vinylidene difluoride)(PVDF)composite electrolytes and Li anode.Benefiting from the physical barrier of the interlayer,the continuous decomposition of PVDF is restrained and the intimate contact between electrode and electrolyte is also achieved to reduce the interface impedance.Moreover,the added K+is utilized to further regulate smooth Li deposition.As a consequence,the symmetric Li|Li cell with coated Li demonstrates steady cycling at 0.4 mAh·cm^(-2) and a high critical current density of 1 mA·cm^(-2).The assembled Li|LiFePO_(4) cell presents outstanding cycling stability(capacity retention of 90%after 400 cycles at 1 C)and good rate performance.The associated pouch cell performs impressive flexibility and safety.This work provides a convenient strategy to achieve stable Li/PVDF interface for high-performance PVDF-based solid state Li metal batteries. | Mengjun Wu Jiangping Song Jiaheng Lei Haolin Tang | 2024 | Nano Research2024，17，3： | 0 |
| 13 | Nucleation growth quenching for superior cluster catalysts显示文摘Cluster catalysts are rapidly growing into an important sub-field in heterogeneous catalysis,owing to their distinct geometric structure,neighboring metal sites,and unique electronic structure.Although the thermodynamics and kinetics of the formation of nanoparticles have been largely investigated,the precise synthesis of clusters in wet chemical methods still faces great challenges.In the study,a quenching strategy of asymmetric temperature in solution for the rapid generation of vacancy-defect rich clusters is reported.The quenching process can be used to synthesize multitudinous metal compound clusters,including metal oxides,fluorides,oxygen-sulfur compounds,and tungstate.For oxygen evolution reaction(OER),IrO_(2)clusters with abundant oxygen vacancies were obtained and uniformly dispersed in the solution.Compared to commercial IrO_(2),the prepared IrO_(2)cluster can be directly loaded on carbon paper and used as binder-free electrodes,which exhibit higher OER activity and long-term operational stability in alkaline electrolytes.The quenching strategy provides a simple and efficient method for the synthesis of clusters,which has tremendous potential for industrial-scale preparation and application,especially can be further applied to flow electrochemical generators. | Ruyue Wang Feng Cheng Yonggang Wang Dongyu Fan Bohan Deng Yuanzheng Long Haolin Tang Kai Huang Zhaowei Qu Ming Lei Binghui Ge Hui Wu | 2022 | Nano Research2022，15，9： | 0 |
| 14 | Partially-Premixed Combustion Characteristics and Thermal Performance of Micro Jet Array Burners with Different Nozzle Spacings显示文摘In order to develop a burner with uniform temperature field,the combustion characteristics and thermal performance of partially premixed methane/air jet flames were experimentally studied by using micro jet array burners.The circular tubes of 1.0-mm inner diameter and 1.5-mm outer diameter were used as nozzles.The effects of nozzle spacing and equivalence ratio on flame phenomenology,temperature distribution and pollutant emissions were respectively investigated by camera photography,thermocouple measurement and sampling analysis.Results show that there are two clean flame patterns:clean merged-flame and clean non-merging flames.The flame patterns depend on the strength of flame interaction,the equivalence ratio of the mixture and the quantity of air entrainment through the gap between nozzles.The burners with small nozzle spacing such as 2 mm and 2.5 mm tend to produce fully merged flame with low equivalence ratio limit and the corresponding temperature fields are very uniform with fluctuations less than 0.3%,but a small increase in equivalence ratio will lead to rapid deterioration of combustion property.The burner with a medium spacing of 3 mm can produce partially merged flame in a wide equivalence ratio range with low emissions,and the temperature fluctuation can be less than 0.5%(<7 K)in the optimal region.The burner with a large spacing of 4 mm will basically form independent array flames with the largest temperature fluctuation over 1%,while it can achieve clean combustion under high equivalence ratio due to large air entrainment.Comprehensive analysis shows that the micro jet array burner with medium nozzle spacing of 3 mm has the best combustion characteristics and thermal performance. | YANG Haolin WU Yong ZENG Xiaojun WANG Xiaohan ZHAO Daiqing | 2021 | Journal of Thermal Science2021，30，5： | 0 |
| 15 | Metal-nitrogen-doped hybrid ionic/electronic conduction triple-phase interfaces for high-performance all-solid-state lithium-sulfur batteries显示文摘The point-to-point contact mechanism in all-solid-state Li-S batteries(ASSLSBs)is not as efficient as a liquid electrolyte which has superior mobility in the electrode,resulting in a slower reaction kinetics and inadequate ionic/electronic conduction network between the S(or Li_(2)S),conductive carbon,and solid-state electrolytes(SSEs)for achieving a swift(dis)charge reaction.Herein,a series of hybrid ionic/electronic conduction triple-phase interfaces with transition metal and nitrogen co-doping were designed.The graphitic ordered mesoporous carbon frameworks(TM-N-OMCs;TM=Fe,Co,Ni,and Cu)serve as hosts for Li_(2)S and Li_(6)PS_(5)Cl(LPSC)and provide abundant reaction sites on the triple interface.Results from both experimental and computational research display that the combination of Cu-N co-dopants can promote the Li-ion diffusion for rapid transformation of Li_(2)S with adequate ionic(6.73×10^(−4)S·cm^(−1))/electronic conductivities(1.77×10^(−2)S·cm^(−1))at 25℃.The as-acquired Li_(2)S/Cu-N-OMC/LPSC electrode exhibits a high reversible capacity(1147.7 mAh·g^(−1))at 0.1 C,excellent capacity retention(99.5%)after 500 cycles at 0.5 C,and high areal capacity(7.08 mAh·cm^(−2)). | Hao Li Jiangping Song Fanglin Wu Rui Wang Dan Liu Haolin Tang | 2023 | Nano Research2023，16，8： | 0 |
| 16 | On-site conversion reaction enables ion-conducting surface on red phosphorus/carbon anode for durable and fast sodium-ion batteries显示文摘The practical applications of high-capacity alloy-type anode materials in sodium-ion batteries(SIBs)are challenged by their vast volume effects and resulting unstable electrode-electrolyte interphases during discharge-charge cycling.Taking red phosphorus(P)/carbon anode material as an example,we report an on-site conversion reaction to intentionally eliminate the volume effect-dominated surface P and yield an ionically conducting layer of Na3PS4solid-state electrolyte on the composite.Such a surface reconstruction can significantly suppress the electrode swelling and simultaneously enable the activation energy of interfacial Na+transfer as low as 36.7 k J mol^(-1),resulting in excellent electrode stability and ultrafast reaction kinetics.Consequently,excellent cycling performance(510 mA h g^(-1)at 5 A g^(-1)after 1000 cycles with a tiny capacity fading rate of 0.016%per cycle)and outstanding rate capability(484 mA h g^(-1)at 10 A g^(-1)are achieved in half cells.When coupled with Na_(3)V_(2)(PO4)3cathode,the full cells exhibit 100%capacity retention over 200 cycles at 5C with an average Coulombic efficiency of 99.93%and a high energy density of 125.5 W h kg^(-1)at a power density of 8215.6 W kg^(-1)(charge or discharge within~49 s).Remarkably,the full cell can steadily operate at a high areal capacity of 1.9 mA h cm^(-2),the highest level among red P-based full SIBs ever reported. | Jiangping Song Xin Peng Dan Liu Hao Li Mengjun Wu Kan Fang Xinxin Zhu Xinyuan Xiang Haolin Tang | 2023 | Journal of Energy Chemistry2023，，5： | 0 |
| 17 | Microstructure refinement-homogenization and flexural strength improvement of Al_(2)O_(3) ceramics fabricated by DLP-stereolithography integrated with chemical precipitation coating process显示文摘In this study,the chemical precipitation coating(CP)process was creatively integrated with DLP-stereolithography based 3D printing for refining and homogenizing the microstructure of 3D printed Al_(2)O_(3) ceramic.Based on this novel approach,Al_(2)O_(3)powder was coated with a homogeneous layer of amorphous Y2O3,with the coated AI2O3 powder found to make the microstructure of 3D printed Al_(2)O_(3) ceramic more uniform and refined,as compared with the conventional mechanical mixing(MM)of Al_(2)O_(3) and Y_(2)O_(3) powders.The grain size of Al_(2)O_(3) in Sample CP is 64.44%and 51.43%lower than those in the monolithic Al_(2)O_(3) ceramic and Sample MM,respectively.Sample CP has the highest flexural strength of 455.37±32.17 MPa,which is 14.85%and 25.45%higher than those of Samples MM and AL,respectively;also Sample CP has the highest Weibull modulus of 16.88 among the three kinds of samples.Moreover,the fine grained Sample CP has a close thermal conductivity to the coarse grained Sample MM because of the changes in morphology of Y_(3)Al_(5)O_(12) phase from semi-connected(Sample MM)to isolated(Sample CP).Finally,specially designed fin-type Al_(2)O_(3) ceramic heat sinks were successfully fabricated via the novel integrated process,which has been proven to be an effective method for fabricating complex-shaped Al_(2)O_(3) ceramic components with enhanced flexural strength and reliability. | Guanglin NIE Yehua LI Pengfei SHENG Fei ZUO Haolin WU Leiren LIU Xin DENG Yiwang BAO Shanghua WU | 2021 | Journal of Advanced Ceramics2021，10，4： | 0 |
| 18 | Promotion of catalytic activity for methanol electro-oxidation on CoPc-Pt/C co-catalysts显示文摘The catalytic activity for methanol electro-oxidation on CoPc-Pt/C co-catalysts, prepared by impregna-tion method, was studied in details through electrochemical methods. Cyclic voltammetry (CV) result demonstrates that CoPc has higher forward anodic peak current density and jf / jb value (forward anodic peak current density/backward anodic peak current density) than Pt/C. Chronoamperometry (CA) analysis indicates that CoPc-Pt/C exhibits both excellent transient current density and stable current density for methanol electro-oxidation compared with Pt/C. Two main mechanisms related to the pro-motion of catalytic activity are as follows: CoPc-Pt/C has the activity of tolerance to carbonaceous in-termediates, thus inhibiting the self-poisoning of catalysts; CoPc-Pt/C owns prominent intrinsic cata-lytic activity indicated by the apparent activation energy for methanol oxidation on CoPc-Pt/C, which is 18 kJ/mol, less than that on Pt and PtRu catalysts as reported. | WU JingJie XU YiMin PAN Mu MA WenTao TANG HaoLin | 2009 | Chinese Science Bulletin2009，54，6： | 0 |
| 19 | Wet-milling synthesis of immobilized Pt/Ir nanoclusters as promising heterogeneous catalysts显示文摘Being a typical state of the art heterogeneous catalyst,supported noble metal catalyst often demonstrates enhanced catalytic properties.However,a facile synthetic method for realizing large-scale and low-cost supported noble metal catalyst is strictly indispensable.To this end,by making use of the strong metal-support interaction(SMSI)and mechanochemical reaction,we introduce an efficient synthetic route to obtain ultrafine Pt and Ir nanoclusters immobilized on diverse substrates by wet chemical milling.We further demonstrate the scaling-up effect of our approach by large-scale ball-milling production of Pt nanoclusters immobilized on TiO_(2)substrate.The synthesized Pt/Ir@Co_(3)O_(4)catalysts exhibit superior oxygen evolution reaction(OER)performance with only 230 and 290 mV overpotential to achieve current density of 10 and 100 mA·cm^(-2),beating the catalytic performance of Co_(3)O_(4)supported Pt or Ir clusters and commercial Ir/C.It is envisioned that the present work strategically directs facile ways for fabricating supported noble metal heterogeneous catalysts. | Peng Du Kai Huang Xiaoyuan Fan Jingteng Ma Naveed Hussain Ruyue Wang Bohan Deng Binghui Ge Haolin Tang Ru Zhang Ming Lei Hui Wu | 2022 | Nano Research2022，15，4： | 0 |
| 20 | Metal organic frameworks as advanced extraction adsorbents for separation and analysis in proteomics and environmental research显示文摘Human health is always under global spotlight, but now it suffers from severe environmental issue and various diseases.Developing highly selective and effective extraction technique for environmental pollutant removal and target protein/peptide molecules conduces to the solution of environmental contamination and early disease detection, which will promise human health to a great degree. Metal-organic frameworks(MOFs) are typical porous nanomaterials featuring rigid structure, large specific surface area, thermal and chemical stability, numerous active sites and easy functionalization. Moreover, multitudinous combination of metal centers and organic ligands often endows MOFs with structure and function diversity. Owing to such splendid merits, MOFs are able to act as advanced adsorbents for sample-pretreatment in proteomics and environmental field,which indicates great efficiency, reproducibility, convenience and cost-effectiveness. In this review, the novel design of MOFs and their applications in proteomics and environmental research are roughly summarized. We first introduce the representative researches of functional MOFs in protein post-translational modifications including glycosylation and phosphorylation, mainly focusing on hydrophilic interaction liquid chromatography(HILIC) or metal-oxide affinity chromatography(MOAC). The important role of MOFs in enzyme immobilization is also covered. Then MOF-based adsorptive removal of diverse environmental contaminants embracing plasticizers, pesticides and varied water pollutants(pharmaceutical and personal care products,organic dyes and heavy metals), in which multiple chemical and non-chemical interactions play a vital role, is emphatically discussed. Finally, we analyze the existing problems and challenges in the way of wider practical applications and put forward prospective anticipation. | Yonglei Wu Haolin Chen Yijie Chen Nianrong Sun Chunhui Deng | 2022 | Science China Chemistry2022，65，4： | 0 |
