| 1 | Using ultrasound to improve the sequential post-synthesis modification method for making mesoporous Y zeolites显示文摘Mesoporous Y zeolites were prepared by the sequential chemical dealumination(using chelating agents such as ethylenediaminetetraacetic acid,H EDTA,and citric acid aqueous solutions)and alkaline desilication(using sodium hydroxide,NaOH,aqueous solutions)treatments.Specifically,the ultrasound-assisted alkaline treatment(i.e.,ultrasonic treatment)was proposed as the alternative to conventional alkaline treatments which are performed under hydrothermal conditions.In comparison with the hydrothermal alkaline treatment,the ultrasonic treatment showed the comparatively enhanced efficiency(with the reduced treatment time,i.e.,5 min vs.30 min,all with 0.2 mol·L NaOH at 65°C)in treating the dealuminated Y zeolites for creating mesoporosity.For example,after the treatment of a dealuminated zeolite Y(using 0.1 mol·L H EDTA at 100°C for 6 h),the ultrasonic treatment produced the mesoporous zeolite Y with the specific external surface area()of 160 m·g and mesopore volume()of 0.22 cm·g,being slightly higher than that by the conventional method(i.e.,=128 m·g and=0.19 cm·g).The acidic property and catalytic activity(in catalytic cracking of-octane)of mesoporous Y zeolites obtained by the two methods were comparable.The ultrasonic desilication treatment was found to be generic,also being effective to treat the dealuminated Y zeolites by citric acid.Additionally,the first step of chemical dealumination treatment was crucial to enable the effective creation of mesopores in the parent Y zeolite(with a silicon-to-aluminium ratio,Si/Al=2.6)regardless of the subsequent alkaline desilication treatment(i.e.,ultrasonic or hydrothermal).Therefore,appropriate selection of the condition of the chemical dealumination treatment based on the property of parent zeolites,such as Si/Al ratio and crystallinity,is important for making mesoporous zeolites effectively. | Rongxin Zhang Peinan Zhong Hamidreza Arandivan Yanan Guan Jinmin Liu Na Wang Yilai Jiao Xiaolei Fan | 2020 | Frontiers of Chemical Science and Engineering2020，14，2： | 5 |
| 2 | A 5.4mW and 6.1% efficiency fixed-tuned 214GHz frequency doubler with Schottky barrier diodes显示文摘A Y-band frequency doubler is analyzed and designed with GaAs planar Schottky diode,which is flip-chip solded into a 50|xm thick quartz substrate.Diode embedding impedance is found by fullwave analysis with lumped port to model the nonlinear junction for impedance matching without the need of diode equivalent circuit model.All the matching circuit is designed 'on-chip' and the multiplier is self-biasing.To the doubler,a conversion efficiency of 6.1%and output power of 5.4mW are measured at 214 GHz with input power of 88 mW,and the typical measured efficiency is 4.5%in200~225GHz. | 姚常飞 Zhou Ming Luo Yunsheng Kou Yanan Li Jiao | 2015 | High Technology Letters2015，21，1： | 4 |
| 3 | Kinetics and mechanism of hexavalent chromium removal by basic oxygen furnace slag显示文摘Basic oxygen furnace slag(BOFS) has the potential to remove hexavalent chromium(Cr(VI))from wastewater by a redox process due to the presence of minerals containing Fe2+. The effects of the solution p H, initial Cr(VI) concentration, BOFS dosage, BOFS particle size, and temperature on the removal of Cr(VI) was investigated in detail through batch tests. The chemical and mineral compositions of fresh and reacted BOFS were characterized using scanning electron microscope(SEM) equipped with an energy dispersive spectrometer(EDS)system and X-ray diffractometer(XRD). The results show that Cr(VI) in wastewater can be efficiently removed by Fe2+released from BOFS under appropriate acidic conditions. The removal of Cr(VI) by BOFS significantly depended on the parameters mentioned above. The reaction of Cr(VI) with BOFS followed the pseudo-second-order kinetic model. Fe2+responsible for Cr(VI) removal was primarily derived from the dissolution of Fe O and Fe3O4 in BOFS. When H2SO4 was used to adjust the solution acidity, gypsum(Ca SO4·2H2O)could be formed and become an armoring precipitate layer on the BOFS surface, hindering the release of Fe2+and the removal of Cr(VI). Finally, the main mechanism of Cr(VI) removal by BOFS was described using several consecutive reaction steps. | Chong Han Yanan Jiao Qianqian Wu Wangjin Yang He Yang Xiangxin Xue | 2016 | Journal of Environmental Sciences2016，28，8： | 4 |
| 4 | Geniposide, the component of the Chinese herbal formula Tongluojiunao, protects amyloid-β peptide(1–42)-mediated death of hippocampal neurons via the non-classical estrogen signaling pathway显示文摘Tongluojiunao(TLJN) is an herbal medicine consisting of two main components, geniposide and ginsenoside Rg1. TLJN has been shown to protect primary cultured hippocampal neurons. However, its mechanism of action remains unclear. In the present study, primary cultured hippocampal neurons treated with Aβ1–42(10 μmol/L) significantly increased the release of lactate dehydrogenase, which was markedly reduced by TLJN(2 μL/mL), specifically by the component geniposide(26 μmol/L), but not ginsenoside Rg1(2.5 μmol/L). The estrogen receptor inhibitor, ICI182780(1 μmol/L), did not block TLJN- or geniposide-mediated decrease of lactate dehydrogenase under Aβ1–42-exposed conditions. However, the phosphatidyl inositol 3-kinase or mitogen-activated protein kinase pathway inhibitor, LY294002(50 μmol/L) or U0126(10 μmol/L), respectively blo cked the decrease of lactate dehydrogenase mediated by TLJN or geniposide. Therefore, these results suggest that the non-classical estrogen pathway(i.e., phosphatidyl inositol 3-kinase or mitogen-activated protein kinase) is involved in the neuroprotective effect of TLJN, specifically its component, geniposide, against Aβ1–42-mediated cell death in primary cultured hippocampal neurons. | Jiao Li Feng Wang Haimin Ding Chunyan Jin Jinyan Chen Yanan Zhao Xiaojing Li Wenju Chen Ping Sun Yan Tan Qi Zhang Xu Wang Angran Fan Qian Hua | 2014 | Neural Regeneration Research2014，9，5： | 3 |
| 5 | Graphene oxide assisted facile hydrothermal synthesis of LiMn_(0.6)Fe_(0.4)PO_4 nanoparticles as cathode material for lithium ion battery显示文摘Assisted by graphene oxide(GO),nano-sized LiMn_(0.6)Fe_(0.4)PO_4 with excellent electrochemical performance was prepared by a facile hydrothermal method as cathode material for lithium ion battery.SEM and TEM images indicate that the particle size of LiMn_(0.6)Fe_(0.4)PO_4(S2)was about 80 nm in diameter.The discharge capacity of LiMn_(0.6)Fe_(0.4)PO_4 nanoparticles was 140.3 mAh-g^1 in the first cycle.It showed that graphene oxide was able to restrict the growth of LiMn_(0.6)Fe_(0.4)PO_4 and it in situ reduction of GO could improve the electrical conductivity of LiMn_(0.6)Fe_(0.4)PO_4 material. | Changchang Xu Li Li Fangyuan Qiu Cuihua An Yanan Xu Ying Wang Yijing Wang Lifang Jiao Huatang Yuan | 2014 | Journal of Energy Chemistry2014，23，3： | 3 |
| 6 | Microstructure Evolution and Pore Formation Mechanism of Porous TiAl3 Intermetallics via Reactive Sintering显示文摘Porous TiAl_3 intermetallics were fabricated through vacuum reactive sintering from Ti–75 Al at.% elemental powder mixture. The phase compositions, expansion behaviors, pore characteristics and microstructure evolution of TiAl_3 intermetallics were investigated, and the pore formation mechanism was also proposed. It was found that the actual temperature of compacts showed an acute climb from 668 to 1244 °C in 166 s, while the furnace temperature maintained the linear growth of 5 °C/min, which indicated that an obvious thermal explosion(TE) reaction occurred during sintering,and only single-phase TiAl_3 intermetallic was synthesized in TE products. The open porosity increased from 22.2(green compact) to 32.8% after reactive diffusion sintering at 600 °C and rised to 58.7% after TE, then decreased to 51.2% after high-temperature homogenization at 1100 °C. Therefore, TE reaction is the dominated pore formation mechanism of porous TiAl_3 intermetallics. The pore evolution in porous TiAl_3 intermetallics occurred by the following mechanisms:certain intergranular pores remained among powder particles of green compact, then low-temperature sintering resulted in a further increase in porosity due to the Kirkendall effect. Moreover, TE reaction gave rise to a dramatic volume expansion because of the rapid increase in temperature, and high-temperature sintering caused densification and a slight shrinkage. | Xinyang Jiao Xiaohong Wang Peizhong Feng Yanan Liu Laiqi Zhang Farid Akhtar | 2018 | Acta Metallurgica Sinica(English Letters)2018，31，4： | 3 |
| 7 | Structured hierarchical Mn–Co mixed oxides supported on silicalite-1 foam catalyst for catalytic combustion显示文摘Silicalite-1(S1)foam was functionalized by supporting manganese-cobalt(Mn-Co)mixed oxides to develop the structured hierarchical catalyst(Mn-Co@SlF)for catalytic combustion for the first time.The self-supporting S1 foam with hierarchical porosity was prepared via hydrothermal synthesis with polyurethane(PU)foam as the template.Subsequently,Mn-Co oxide nano sheets were uniformly grown on the surface of S1 foams under hydrothermal conditions to prepare the structured hierarchical catalyst with specific surface area of 354 m^2·g^-1,micropore volume of 0.141 cm^3·g^-1 and total pore volume of 0.217 cm3·g^-1,as well as a good capacity to adsorb toluene(1.7 mmol·g^-1 at p/p0=0.99).Comparative catalytic combustion of toluene of over developed structured catalyst Mn-Co@SlF was performed against the control catalysts of bulk Mn-Co@S1(i.e.,the crushed Mn-Co@SlF)and unsupported Mn-Co oxides(i.e.,Mn-Co).Mn-Co@SlF exhibited comparatively the best catalytic performance,that is,complete and stable toluene conversion at 2480 C over 65 h due to the synergy between Mn-Co oxides and S1 foam,which provided a large number of oxygen vacancies,high redox capacity.In addition,the hierarchical porous structure also improved the accessibility of active sites and facilitated the global mass transfer across the catalyst bed,being beneficial to the catalysis and catalyst longevity. | Yanan Guan Hengyu Shen Xing Guo Boyang Mao Zhenyuan Yang Yangtao Zhou He Liang Xiaolei Fan Yilai Jiao jinsong Zhang | 2020 | Chinese Journal of Chemical Engineering2020，28，9： | 3 |
| 8 | In situ self-assembled organoid for osteochondral tissue regeneration with dual functional units显示文摘The regeneration of hierarchical osteochondral units is challenging due to difficulties in inducing spatial,directional and controllable differentiation of mesenchymal stem cells(MSCs)into cartilage and bone compartments.Emerging organoid technology offers new opportunities for osteochondral regeneration.In this study,we developed gelatin-based microcryogels customized using hyaluronic acid(HA)and hydroxyapatite(HYP),respectively for inducing cartilage and bone regeneration(denoted as CH-Microcryogels and OS-Microcryogels)through in vivo self-assembly into osteochondral organoids.The customized microcryogels showed good cytocompatibility and induced chondrogenic and osteogenic differentiation of MSCs,while also demonstrating the ability to self-assemble into osteochondral organoids with no delamination in the biphasic cartilage-bone structure.Analysis by mRNA-seq showed that CH-Microcryogels promoted chondrogenic differentiation and inhibited inflammation,while OS-Microcryogels facilitated osteogenic differentiation and suppressed the immune response,by regulating specific signaling pathways.Finally,the in vivo engraftment of pre-differentiated customized microcryogels into canine osteochondral defects resulted in the spontaneous assembly of an osteochondral unit,inducing simultaneous regeneration of both articular cartilage and subchondral bone.In conclusion,this novel approach for generating self-assembling osteochondral organoids utilizing tailor-made microcryogels presents a highly promising avenue for advancing the field of tissue engineering. | Zhen Yang Bin Wang Wei Liu Xiaoke Li Kaini Liang Zejun Fan Jiao Jiao Li Yudi Niu Zihao He Hui Li Du Wang Jianjing Lin Yanan Du Jianhao Lin Dan Xing | 2023 | Bioactive Materials2023，，9： | 2 |
| 9 | A low dose cell therapy system for treating osteoarthritis:In vivo study and in vitro mechanistic investigations显示文摘Mesenchymal stem cells(MSCs)can be effective in alleviating the progression of osteoarthritis(OA).However,low MSC retention and survival at the injection site frequently require high doses of cells and/or repeated injections,which are not economically viable and create additional risks of complications.In this study,we produced MSC-laden microcarriers in spinner flask culture as cell delivery vehicles.These microcarriers containing a low initial dose of MSCs administered through a single injection in a rat anterior cruciate ligament(ACL)transection model of OA achieved similar reparative effects as repeated high doses of MSCs,as evaluated through imaging and histological analyses.Mechanistic investigations were conducted using a co-culture model involving human primary chondrocytes grown in monolayer,together with MSCs grown either within 3D constructs or as a monolayer.Co-culture supernatants subjected to secretome analysis showed significant decrease of inflammatory factors in the 3D group.RNA-seq of co-cultured MSCs and chondrocytes using Gene Ontology and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analysis revealed processes relating to early chondrogenesis and increased extracellular matrix interactions in MSCs of the 3D group,as well as phenotypic maintenance in the co-cultured chondrocytes.The cell delivery platform we investigated may be effective in reducing the cell dose and injection frequency required for therapeutic applications. | Bin Wang Wei Liu Jiao Jiao Li Senlin Chai Dan Xing Hongsheng Yu Yuanyuan Zhang Wenjin Yan Zhihong Xu Bin Zhao Yanan Du Qing Jiang | 2022 | Bioactive Materials2022，7，1： | 2 |

| 11 | Novel application of LiCoO_2 as a high-performance candidate material for supercapacitor显示文摘Electrochemical performances of LiCoO2 as a candidate material for supercapacitor are systematically investigated. LiCoO2 nanomaterials are synthesized via hydrothermal reaction with consequent calcination process. And the particle size increases as the calcination temperature rises.LCO-650 sample with the largest particle size displays the maximum capacitances of 817.5 Fg-1with the most outstanding capacity retention rate of 96.8% after 2000 cycles. It is shown that large particle size is beneficial to the electrochemical and structural stability of Li CoO2 materials. We speculate that the micron-sized waste LiCoO2 materials have great potential for supercapacitor application. It may provide a novel recovered approach for spent LIBs and effectively relieve the burdens on the resource waste and environment pollution. | Yanan Xu Liangzhong Ding Tongsheng Zhong Xiao Han Lifang Jiao Huatang Yuan Yijing Wang | 2015 | Journal of Energy Chemistry2015，24，2： | 1 |

| 14 | Synergistic effects of silver nanoparticles and cisplatin in combating inflammation and hyperplasia of airway stents显示文摘Anti-inflammatory and antihyperplasia activities are essential requirements for the successful use of airway stents.In this work,silver nanoparticles(AgNPs)and cisplatin(DDP)were combined in a synergistic modification strategy to improve the surface function of airway stents.Using polycaprolactone(PCL)as a drug carrier,a dual-functional PCL-AgNPs-DDP fiber film-coated airway stent was fabricated by electrospinning.The physicochemical and biological properties of the obtained fiber films were examined.The ATR-FTIR,XPS,SEM-EDS and TEM results suggested that AgNPs and DDP could be successfully immobilized onto the airway stent surface.The drug release and surface degradation results revealed that AgNPs and DDP can undergo sustained release from films for 30 d,and the weight loss was approximately 50%after 35 d.In addition,the dual-functional fiber film suppressed human embryonic lung fibroblast growth and exhibited excellent antibacterial activity against Staphylococcus aureus,Pseudomonas aeruginosa and Candida albicans.Furthermore,the effectiveness of the dual-functional fiber film-coated airway stent was evaluated by application to the trachea of New Zealand rabbits.The in vivo results indicated that PCL-AgNPs-DDP fiber film-coated airway stent can significantly inhibit granulation tissue formation and collagen deposition,reduced the expression of IL-8,TNF-α,IL-1α,PCNA,α-SMA and CD68,and ultimately achieved anti-inflammatory and antihyperplasia effects.Hence,this study provides a dual-functional surface-coated airway stent to address the clinical complications associated with respiratory tract inflammation and granulation tissue hyperplasia,thus inhibiting tracheal stenosis. | Zhaonan Li Chuan Tian Dechao Jiao Jing Li Yahua Li Xueliang Zhou Huiping Zhao Yanan Zhao Xinwei Han | 2022 | Bioactive Materials2022，7，3： | 1 |
| 15 | Additive manufacturing of sodalite monolith for continuous heavy metal removal from water sources显示文摘Herein,we present a simple strategy for preparing monolithic sodalite adsorbents via sequential additive manufacturing and post-treatments.In detail,the method includes(i)3D printing of cylindrical monoliths using clay as the base material;(ii)thermal activation of the 3D-printed clay monoliths by calcination(to produce reactive alumina and silica species and enable mechanical stabilization);(iii)conversion of the activated clay monoliths to hierarchical porous sodalite monoliths via hydrothermal alkaline treatment.Parametric studies on the effect of calcination temperature,alkaline concentration and hydrothermal treatment time on the property of the resulting materials(such as phase composition and morphology)at different stages of preparation was conducted.Under the optimal conditions(i.e.,calcination temperature of 850℃,NaOH concentration of 3.3 mol·L^(-1),reaction temperature of 150℃,and reaction time of 6 h),a high-quality pure sodalite monolith was obtained,which possesses a relatively high BET surface area(58 m^(2)·g^(-1))and hierarchically micro-meso-macroporous structure.In the proposed application of continuous removal of heavy metals(chromium ion as the model)from wastewater,the developed 3D-printed sodalite monolith showed excellent Cr^(3+)removal performance and fast kinetics(~98%removal efficiency within 25 cycles),which outperformed the packed bed using sodalite pellets(made by extrusion). | Hengyu Shen Run Zou Yangtao Zhou Xing Guo Yanan Guan Duo Na Jinsong Zhang Xiaolei Fan Yilai Jiao | 2022 | Chinese Journal of Chemical Engineering2022，35，2： | 1 |

| 17 | Folic acid-based supramolecules for enhanced stability in potassium ion batteries显示文摘Organics present significant prospects as environmentally friendly and sustainable electrode materials for potassium ion batteries(PIBs)because of their abundant,recyclable and highly customizable characteristics.However,small molecular organics are easily solubilized in organic electrolytes,resulting in a low capacity and poor stability.Herein,the folic acid-based supermolecules(SM-FAs)are successfully prepared by a hydrothermal assisted self-assembly strategy.Due to multi-locus hydrogen bonds(HBs)and the cyclizedπ-conjugated interactions,the structural stability of SM-FAs has been significantly improved,and the solubility in carbonate electrolytes has been effectively inhibited.As an anode for PIB,the SM-FA-6sample exhibits a large capacity(206 mAh/g at 50 mA/g)and an outstanding cycle stability(capacity retention of 91%after 1000 cycles at 50 m A/g).More impressively,an integrative storage mechanism which combines both the general enolization reaction between C=O groups and K^(+),and the atypicalπ–K^(+)interaction within the assembled conjugation framework,is unraveled for potassium ion accumulation.It is envisioned that this facile self-assemble strategy opens up a promising avenue to modulate the stability of small molecular organic electrodes with enhanced storage capacity. | Yanan Wang Dandan Ouyang Liuqian Yang Chunyan Wang Jian Sun Hui Zhu Jiao Yin | 2023 | Chinese Chemical Letters2023，34，9： | 0 |
| 18 | Tungsten oxide nanowires and polyaniline hybrid film-based electrochromic device with multicolor display and enhanced capacitance显示文摘Electrochromic devices(ECDs)have exhibited promising applications in the fields of energy-saving intelligent buildings and next-generation displays because of their simple structure,low power consumption,and multicolor displays.W_(18)O_(49)/polyaniline(PANI)hybrid films are prepared and assembled to ECDs.Compared with pure PANI and W_(18)O_(49) films,the hybrid film exhibits superior electrochemical and electrochromic performance,including high optical modulation(70.2%),large areal capacity(79.6 mF/cm^(2)),and good capacitance retention.The excellent electrochemical and electrochromic performance is ascribed to the formation of the donor(PANI)-acceptor(W_(18)O_(49))pair,the porous structure in the nanowires,and the large surface area,which enhance electron delocalization of the W_(18)O_(49)/PANI,improve the ion diffusion rate,and increase the charge storage sites.Furthermore,benefitting from the outstanding optical,electrical,and multifunctional properties,the W_(18)O_(49)/PANI hybrid film-based ECD platform is expected to play an important role in electrochromism and energy storage. | Yanan Chen Jiao Lei Yanling Zhai Zhijun Zhu Weitai Wu Xiaoquan Lu | 2023 | Chinese Chemical Letters2023，34，11： | 0 |
| 19 | Defect-modulated synthesis and optoelectronic properties in chemical vapor deposited CsPbBr_(3) microplates显示文摘The remarkable optoelectronic features of halide perovskite promote their potential applications in semiconductor devices beyond solar cells,which require high-quality single crystals with controlled defect levels.Herein,we investigated the synthesis mechanism of chemical vapor deposited single-crystalline all-inorganic perovskite microplates(MPs),and reported a defect-modulated photocurrent which is closely related to the growth sequence of the MPs.The MP synthesis initiates from island-like nano-disks,and subsequently transits to a layer-by-layer fashion,resulting in a defect-rich area at the center of the MPs.At elevated temperatures,these central defects may be thermally activated and become highly mobile,leading to photoluminescence quenching and degression of local and overall optoelectronic attributes,as evidenced by the spatial resolved optical and electrical scanning probe microscopy.Overall,this work shines light on the formation,proliferation and dynamics of defects in perovskites,and offers guidance for preparation of high-quality perovskites micro-crystals for functional semiconductor devices with high temperature stability. | Yanan Bao Hengshan Wang Meiqi An Huayi Tang Jing Li Jianliang Li Conghui Tan Yingmin Luo Jiao Xu Yiming Yang | 2024 | Nano Research2024，17，5： | 0 |
| 20 | Significantly enhanced superconductivity in monolayer FeSe films on SrTiO_(3)(001) via metallic δ-doping显示文摘Superconductivity transition temperature(T_(c))marks the inception of a macroscopic quantum phase-coherent paired state in fermionic systems.For 2D superconductivity,the paired electrons condense into a coherent superfluid state at Tc,which is usually lower than the pairing temperature,between which intrinsic physics including Berezinskii-Kosterlitz-Thouless transition and pseudogap state are hotly debated.In the case of monolayer FeSe superconducting films on SrTiO_(3)(001),although the pairing temperature(T_(p))is revealed to be 65-83 K by using spectroscopy characterization,the measured zero-resistance temperature(T_(c)^(0))is limited to 20 K.Here,we report significantly enhanced superconductivity in monolayer FeSe films by δ-doping of Eu or Al on SrTiO_(3)(001)surface,in which T_(c)^(0) is enhanced by 12 K with a narrowed transition width ΔT_(c)~8 K,compared with non-doped samples.Using scanning tunneling microscopy/spectroscopy measurements,we demonstrate lowered work function of the δ-doped SrTiO_(3)(001)surface and enlarged superconducting gaps in the monolayer FeSe with improved morphology/electronic homogeneity.Our work provides a practical route to enhance 2D superconductivity by using interface engineering. | Xiaotong Jiao Wenfeng Dong Mingxia Shi Heng Wang Cui Ding Zhongxu Wei Guanming Gong Yanan Li Yuanzhao Li Binjie Zuo Jian Wang Ding Zhang Minghu Pan Lili Wang Qi-Kun Xue | 2024 | National Science Review2024，11，3： | 0 |
