| 1 | Progress in hole-transporting materials for perovskite solar cells显示文摘In recent years the photovoltaic community has witnessed the unprecedented development of perovskite solar cells(PSCs) as they have taken the lead in emergent photovoltaic technologies. The power conversion efficiency of this new class of solar cells has been increased to a point where they are beginning to compete with more established technologies. Although PSCs have evolved a variety of structures, the use of hole-transporting materials(HTMs) remains indispensable. Here, an overview of the various types of available HTMs is presented. This includes organic and inorganic HTMs and is presented alongside recent progress in associated aspects of PSCs, including device architectures and fabrication techniques to produce high-quality perovskite films. The structure, electrochemistry, and physical properties of a variety of HTMs are discussed, highlighting considerations for those designing new HTMs. Finally, an outlook is presented to provide more concrete direction for the development and optimization of HTMs for highefficiency PSCs. | Xichuan Yang Haoxin Wang Bin Cai Ze Yu Licheng Sun | 2018 | Journal of Energy Chemistry2018，27，3： | 3 |
| 2 | Combined effects of obstacle and fine water mist on gas explosion characteristics显示文摘Combined effects of obstacles and fine water mist on a methane-air explosion of a semi-closed pipe were investigated experimentally.In this study,the diameter of the water mist,the location,and the number of obstacles was considered.The results demonstrated that 5 μm water mist present a significant suppression affected while 45 μm shows a slight promotion effected on a gas explosion of the condition without obstacles.In the presence of an obstacle,however,the inhibitory effect of 5 μm water veils of mist dropped significantly during flame propagation,and the effect of 45 μm water veils of mist changed from the enhancement of inhibition,and its inhibitory effect was significant.The inhibitory effect of 45 μm water veils of mist on gas explosion weakened firstly and then enhanced with the increasing distance between obstacle location from the ignition location as well as in several obstacles. | Xiaoping Wen Mengming Wang Fahui Wang Minggao Yu Haoxin Deng | 2021 | Chinese Journal of Chemical Engineering2021，34，12： | 3 |
| 3 | Isolation and Preliminary Identification of Broad-spectrum Bacteriocin-producing Lactobacillus Strain CW3显示文摘[Objective]This study aimed to screen and preliminarily identify Lactobacillus strain CW3. [Method]Oxford cup double-plate method was used for preliminary screening of broad-spectrum bacteriocin-producing Lactobacillus strain; after eliminating the interference of organic acid and hydrogen peroxide,antibacterial substances containing protein properties produced by the screened strain were detected; finally,the obtained strain was identified. [Result]After elimination of interference factors such as organic acid and hydrogen peroxide,the fermentation supernatant of strain CW3 could still inhibit the growth of indicator strains; the antibacterial activity of fermentation broth was significantly reduced after treatment with trypsase and pepsase,which indicated that the produced antibacterial substances were bacteriocins. Results of physiological and biochemical identification showed that strain CW3 belonged to Lactobacillus plantarum. [Conclusion]CW3is a broad-spectrum bacteriocin-producing Lactobacillus plantarum strain. | Haoxin LV Weidong WANG Zhongfang TAN Feifei YANG Yingchun JIAO Yanping WANG Zongwei LI | 2014 | Agricultural Biotechnology2014，3，1： | 2 |
| 4 | Spatial Pattern and Influencing Factors of Regional Ecological Civilisation Construction in China显示文摘Ecological civilisation construction is a strategy for regional sustainable development based on a regional system of human-land relations. The comprehensive measurement and regional differentiation in construction levels are the key issues of ecological civilisation construction. This study aims to build 35 index systems that coalesce on four aspects: ecological economic adjustment and operation, ecological and social development and progress, ecological resources and environmental security, and ecological institutional and cultural awareness. We measured and evaluated the level of ecological civilisation construction of 329 cities(prefecture-level cities, autonomous prefectures and leagues) in 2018 using a comprehensive evaluation system and a spatial autocorrelation method to assess spatial differences in the level of ecological civilisation construction across China. This approach takes ‘the humanities-economic geography’ comprehensive perspective and uses a GWR(geographically weighted regression) model to analyse 10 influencing factors. Results show that: 1) the level of ecological construction can be divided into five types: higher, high, medium, low, and lower levels, according to the evaluation score. The five types are spindle-shaped in quantity and there is a significant imbalance in their spatial distribution, mainly trending from the southeast coast to the northwest. The land is decreasing, and the southern region is higher in level than the northern region. 2) The results of the spatial autocorrelation method show obvious spatial differences in ecological civilisation construction across China and that the level of ecological civilisation construction is positively autocorrelated. From east to west, the hot zone gradually transitions to a cold zone. A high-high type is mainly distributed in eastern coastal cities of China, and the number of high-low and low-high types are small. The low-low type is mainly distributed in the northwestern and northeastern regions. 3) The effect of influencing factors is heterogeneous in their spatial distribution, and the abundance of ecological resources is the most influential factor. According to the main influencing factors, each region should adhere to the principle of differentiation according to local conditions when choosing its ecological civilisation construction path and establishing an assessment mechanism. This study provides a scientific basis for enriching the regional level measurement of ecological civilisation construction, clarifying the current level of ecological civilisation construction in China, and implementing the regional differentiation path of ecological civilisation construction. | DU Yan QIN Welshan SUN Jianfeng WANG Xiaohui GU Haoxin | 2020 | Chinese Geographical Science2020，30，5： | 1 |
| 5 | Lysohexaenetides A and B,linear lipopeptides from Lysobacter sp.DSM 3655 identified by heterologous expression in Streptomyces显示文摘Lysobacter harbors a plethora of cryptic biosynthetic gene clusters(BGCs),albeit only a limited number have been analyzed to date.In this study,we described the activation of a cryptic polyketide synthase(PKS)/nonribosomal peptide synthetase(NRPS)gene cluster(lsh)in Lysobacter sp.DSM 3655 through promoter engineering and heterologous expression in Streptomyces sp.S001.As a result of this methodology,we were able to isolate two novel linear lipopeptides,lysohexaenetides A(1)and B(2),from the recombinant strain S001-lsh.Furthermore,we proposed the biosynthetic pathway for lysohexaenetides and identified LshA as another example of entirely iterative bacterial PKSs.This study highlights the potential of heterologous expression systems in uncovering cryptic biosynthetic pathways in Lysobacter genomes,particularly in the absence of genetic manipulation tools. | XU Qiushuang ZOU Haochen PAN Chen WANG Haoxin SHEN Yuemao LI Yaoyao | 2023 | Chinese Journal of Natural Medicines2023，21，6： | 1 |
| 6 | Renewable isosorbide-derived poly(phosphoester) for simultaneously enhanced flame-retardancy and mechanical property of polylactide显示文摘Incorporating flame retardant fillers is the most efficient way to improve the fire resistance of polylactide(PLA).However,most flame retardant fillers result in deterioration of the mechanical property of PLA so far.Therefore,to create high-performance PLA materials combining excellent flame retardancy with superior mechanical properties remains highly attractive and challenging.In this study,a novel isosorbide-derived poly(phosphoester)(PIDI)was synthesized and used as a bio-based flame-retardant for PLA.The addition of PIDI showed a marginal effect on the change of the glass transition temperature of the PLA composites,but the crystallinity degree of the PLA composites was improved by the inclusion of PIDI.Benefitting from the improved crystallinity,the tensile strength,flexural strength,and impact strength of PLA composite containing 15 wt%PIDI was enhanced by19.4%,14.1%,and 36.9%,respectively,compared to the virgin PLA.With the addition of 20 wt%PIDI,the PLA composite showed an LOI value of 25.5%and a UL-94 V-0 rating in the vertical burning test.The flame retardant effect of PIDI was also demonstrated by a notable reduction(-46%)in the peak heat release rate(PHRR)of PLA composite containing 20 wt%PIDI.Such a renewable isosorbide-derived poly(phosphoester)is one of the promising candidates for PLA bio-composites with an outstanding balance between flame retardancy and intrinsic physical properties. | Xin Wang Haoxin Niu Wenwen Guo Lei Song Yuan Hu | 2021 | Progress in Natural Science:Materials International2021，31，4： | 1 |
| 7 | Upconversion nanoparticles regulated drug&gas dual-effective nanoplatform for the targeting cooperated therapy of thrombus and anticoagulation显示文摘Thromboembolism is the leading cause of cardiovascular mortality.Currently,for the lack of targeting,short half-life,low bioavailability and high bleeding risk of the classical thrombolytic drugs,pharmacological thrombolysis is usually a slow process based on micro-pumping.In addition,frequently monitoring and regulating coagulation functions are also required during(and after)the process of thrombolysis.To address these issues,a targeted thrombolytic and anticoagulation nanoplatform(UCATS-UK)is developed based on upconversion nanoparticles(UCNPs)that can convert 808 or 980 nm near-infrared(NIR)light into UV/blue light.This nanoplatform can target and enrich in the thrombus site.Synergistic thrombolysis and anticoagulation therapy thus could be realized through the controlled release of urokinase(UK)and nitric oxide(NO).Both in vitro and in vivo experiments have confirmed the excellent thrombolytic and anticoagulative capabilities of this multifunctional nanoplatform.Combined with the unique fluorescent imaging capability of UCNPs,this work is expected to contribute to the development of clinical thrombolysis therapy towards an integrated system of imaging,diagnosis and treatment. | Shichen Liu Yao Sun Teng Zhang Longtao Cao Zhiwei Zhong Haoxin Cheng Qingqing Wang Zhuang Qiu Weimin Zhou Xiaolei Wang | 2022 | Bioactive Materials2022，7，12： | 1 |

| 10 | Climate change and water security in the northern slope of the Tianshan Mountains显示文摘Water security is under threat worldwide from climate change. A warming climate would accelerate evaporationand cryosphere melting, leading to reduced water availability and unpredictable water supply. However, thewater crisis in the Northern Slope of Tianshan Mountains(NSTM) faces dual challenges because water demandsforfast-growing urban areas have put heavy pressure on water resources. The mountain-oasis-desert system featuresglacier-fed rivers that sustain intensive water use in the oasis and end in the desert as fragile terminal lakes.The complex balance between water conservation and economic development is subtle. This paper investigateschanges in hydroclimatic variables and water security-related issues on the NSTM. The spatiotemporal variationsin glaciers, climatic variables, rivers, lakes and reservoirs, groundwater, surface water, human water use, andstreamflow were analyzed for the past four decades. The results show that temperature in the NSTM exhibitedan apparent upward trend with a more significant warming rate in the higher altitude regions. Glacier massloss and shrinkage was strong. The average annual streamflow increased from 1980-1989 to 2006–2011 at mosthydrological stations. The monthly dynamics of surface water area showed notable variability at both inter-annual and seasonal scales, revealing the impacts of both natural and anthropogenic drivers on surface wateravailability in the region. The terrestrial water storage anomaly showed a decreasing trend, which might berelated to groundwater pumping for irrigation. Human water use for agriculture and industry grew with theincrease in cultivated land area and gross domestic product (GDP). The increased agricultural water use wasstrongly associated with the expansion of oases. It is unclear whether water availability would remain high underfuture climatic and hydrological uncertainties, posing challenges to water management. In the context of rapidurban growth and climate change, balancing water for humans and nature is vital in achieving the SustainableDevelopment Goals (SDGs) in NSTM. This study provides a baseline understanding of the interplay among water,climate change, and socio-economic development in NSTM. It would also shed light on wise water managementunder environmental changes for other rapidly developing mountain-oasis-desert systems worldwide. | Qiuhong Tang Xingcai Liu Yuanyuan Zhou Puyu Wang Zhongqin Li Zhixin Hao Suxia Liu Gang Zhao Bingqi Zhu Xinlin He Fadong Li Guang Yang Li He Haoxin Deng Zongxia Wang Xiang Ao Zhi Wang Paul P.J.Gaffney Lifeng Luo | 2022 | Geography and Sustainability2022，3，3： | 1 |
| 11 | Yellow responsive material based modification to reduce earphone induced Infection and hearing loss显示文摘Today,earphones have almost been owned by everyone.However,wearing earphones for a long time can cause two serious problems:(1)irreversible damage to hearing;(2)rapid proliferation of bacteria in the ear canal.Herein,an earphone modification strategy is developed for the first time,to reduce hearing loss and inhibit bacteria simultaneously.This earphone is equipped with a high purity yellow light(YL)light-emitting diode chip developed by our university.Then,the surface of the earphone is loaded with porous zinc oxide and silver nanoparticle composite material(ZnO-Ag)that can respond to the YL.Under the excitation of YL,the porous ZnO-Ag can release reactive oxygen species with strong antibacterial activity.More importantly,we discover that YL can reduce the expression of matrix metalloproteinase-3,the secretion of inflammatory factors,and apoptosis in the cochlea,thereby effectively reduce hearing loss. | Haoxin Cheng Hongmei Liu Zhiqiang Liu Ziying Xu Xiaorong Liu Shuang Jia Chaonan He Shichen Liu Jiao Zhang Xiaolei Wang | 2022 | Nano Research2022，15，7： | 0 |
| 12 | Compositional engineering for lead halide perovskite solar cells显示文摘Since metal halide perovskites were utilized as visible-light-harvesting materials for solar cells in 2009,power conversion efficiencies(PCEs)for metal halide perovskite solar cells(PSCs)have already reached to a certified value of 25.7%,making PSCs to be a promising next-generation photovoltaic technology[1−5].Compositional engineering of perovskite materials is an effective approach for achieving highly efficient and stable PSCs[6−8]. | Haoxin Wang Lixiu Zhang Ming Cheng Liming Ding | 2022 | Journal of Semiconductors2022，43，8： | 0 |
| 13 | High isotropic dispiro structure hole transporting materials for planar perovskite solar cells显示文摘Two novel fluorene-based hole transporting materials (HTMs) were synthesized to be used in perovskite solar cells (PSCs). C102 was designed based on C101 by simply linking the two carb on-carbon single bonds to compose a 'dispiro' structure. Their typically similar structures cause them sharing almost the same energy levels. However, their photovoltaic performances are quite different due to the small variations. The PSC that contained the 'dispiro' structure, C102, reached a power conversion efficiency (PCE) of 17.4%, while the device contained C101, obtained a lower PCE of 15.5%. Electrochemical properties and Photovoltaic characterization of the two materials have been investigated to explain the result. It is shown that C102 has a stronger ability to transport holes and resist the charge recombination. Thus, the dispiro structure should be more appropriate being used as HTM in PSCs. | Bin Cai Xichuan Yang Haoxin Wang Weihan Wang Jincheng An Licheng Sun | 2019 | Journal of Energy Chemistry2019，28，5： | 0 |
| 14 | Influences of fluorination on homoleptic iridium complexes with C^N=N type ligand to material properties, ligand orientation and OLED performances显示文摘Two new iridium complexes with C^N=N type ligand(i.e., Ir(BFPPya)3{tris[3,6-bis(4-fluorophenyl)pyridazine]iridium(III)} and Ir(BDFPPya)3{tris[3,6-bis(2,4-di-fluorophenyl)pyridazine]iridium(III)}) attaching with fluorine atoms, were synthesized and the effects of fluorination on the material properties and device performance were investigated. Compared with our previously reported fluorine-free analogue material, that is Ir(BPPya)3{tris[3,6-bis(phenyl)pyridazine]iridium(III)}, blue shifts in the emission spectra as well as in the long wavelength region of the absorptions were observed. The photoluminescence quantum yield(PLQY)(0.44 and 0.84 vs. 0.29), phosphoresces lifetime(0.88 and 1.31 vs. 0.66 μs), and oxidation potential(1.10 and 1.37 vs. 0.95 V) increased obviously after fluorinating the ligand. In contrast, the thermal stability of the iridium complexes decreased slightly(Td: 435 and 402 vs. 440 °C). In the density functional theory(DFT) calculations, by comparing the steric shape of the three ligands within one optimized molecule, orientational differences among the complexes were observed. In OLED device studies, bluish green electroluminescence with peak emission of 500 nm, using the electron-transporting host of TPBI [2,2',2''-(1,3,5-benzenetriyl)tris(1-phenyl-1H-benzimidazole)] and the most fluorinated dopant of Ir(BDFPPya)3, was achieved with maximum efficiency of 20.3 cd/A. On one hand this efficiency is not satisfactory considering a high PLQY of 0.84. On the other hand with the similar device structure, that the(HOMO-LUMO)s of all the dopants are wrapped within that of the host TPBI, and all the triplet energies of the dopants are smaller than that of the host TPBI, it is abnormal that the ordering of device efficiencies is contradictory to that of PLQY. Assisting with the phosphorescent spectrum of TPBI and the absorption spectra of the dopant, the contradiction was interpreted reasonably. | Chen Liu Le Mao Haoxin Jia Zhangjin Liao Hongjiao Wang Baoxiu Mi Zhiqiang Gao | 2015 | Science China Chemistry2015，58，4： | 0 |
| 15 | Convexification Technique for Optimal Thermal-Wind-Photovoltaic Coordination Dispatch Incorporating an Energy Storage System显示文摘This paper proposes a solution to implementing acoordinated optimal day-ahead dispatch in a hybrid thermalwind-photovoltaic power system incorporating an energy storagesystem (ESS). Our aim is to minimize total generation costand restrain the frequent change of ESS charging/dischargingstatus while meeting a series of system operating constraints,including a proposed coordinated dispatch strategy for thepurpose of reducing thermal power fluctuations. A novel twostage convexification technique (TSCT) is designed and leveragedto convert the original non-convex optimal day-ahead dispatchmodel, without taking into account the constraints of the proposed coordinated dispatch strategy into two convex quadraticprogramming problems. When introducing the constraint ofthe coordinated dispatch strategy, the corresponding inequalityconstraints are transformed into a series of linear equalityconstraints, after which the original optimal day-ahead dispatchmodel can be solved by the TSCT mentioned above. Finally,numerical simulations and comparative analysis are performedon the IEEE standard test systems to verify the validity andeffectiveness of the proposed model and method. | Haoxin Wang Libao Shi | 2023 | CSEE Journal of Power and Energy Systems2023，9，6： | 0 |
| 16 | CeO_(2-x) modified Ru/γ-Al_(2)O_(3) catalysts for ammonia decomposition reaction显示文摘Developing high-performance ammonia decomposition catalysts for preparing COx-free hydrogen shows great practical significance.Herein,CeO_(2) is used as a promoter to modulate the metal-support interaction to enhance the catalytic performance of Ru/Al_(2)O_(3) catalysts.A series of 1Ru/xCe-10AI(x=0.5,1,or 3)catalysts was prepared by a facile colloidal deposition method.We find that the optimized 1 Ru/1Ce-10Al catalyst exhibits excellent activity for the decomposition of ammonia with a very high hydrogen yield of7097 mmolH2/(gRu·min)at 450℃.It is confirmed that Ru species are highly dispersed on the support surface as stable small clusters(~1.3 nm).More importantly,due to the interaction between Ru species and partially reduced CeO_(2-x),the electron density of Ru species is increased,which is beneficial to the high activity of the 1 Ru/xCe-10Al catalysts.This work paves a way to construct high-efficiency ammonia decomposition catalysts modified by CeO_(2). | Qinglu Meng Haoxin Liu Kai Xu Weiwei Wang Chunjiang Jia | 2023 | Journal of Rare Earths2023，41，6： | 0 |
