| 2 | Application of waste frying oils in the biosynthesis of biodemulsifier by a demulsifying strain Alcaligenes sp.S-XJ-1显示文摘Exploration of biodemulsifiers has become a new research aspect.Using waste frying oils(WFOs) as carbon source to synthesize biodemulsifiers has a potential prospect to decrease production cost and to improve the application of biodemulsifiers in the oilfield.In this study,a demulsifying strain,Alcaligenes sp.S-XJ-1,was investigated to synthesize a biodemulsifier using waste frying oils as carbon source.It was found that the increase of initial pH of culture medium could increase the biodemulsifier yield but decrease the demulsification ratio compared to that using paraffin as carbon source.In addition,a biodemulsifier produced by waste frying oils and paraffin as mixed carbon source had a lower demulsification capability compared with that produced by paraffin or waste frying oil as sole carbon source.Fed-batch fermentation of biodemulsifier using waste frying oils as supplementary carbon source was found to be a suitable method.Mechanism of waste frying oils utilization was studied by using tripalmitin,olein and tristearin as sole carbon sources to synthesize biodemulsifier.The results showed saturated long-chain fatty acid was diffcult for S-XJ-1 to utilize but could effectively enhance the demulsification ability of the produced biodemulsifier.Moreover,FT-IR result showed that the demulsification capability of biodemulsifiers was associated with the content of C=O group and nitrogen element. | Jia Liu Kaiming Peng Xiangfeng Huang Lijun Lu Hang Cheng Dianhai Yang Qi Zhou Huiping Deng | 2011 | Journal of Environmental Sciences2011,23,6: | 4 |
| 3 | Ultrafast growth of large single crystals of monolayer WS2 and WSe2显示文摘Monolayer transition metal dichalcogenides(TMDs)have attracted considerable attention as atomically thin semiconductors for the ultimate transistor scaling.For practical applications in integrated electronics,large monolayer single crystals are essential for ensuring consistent electronic properties and high device yield.The TMDs available today are generally obtained by mechanical exfoliation or chemical vapor deposition(CVD)growth,but are often of mixed layer thickness,limited single crystal domain size or have very slow growth rate.Scalable and rapid growth of large single crystals of monolayer TMDs requires maximization of lateral growth rate while completely suppressing the vertical growth,which represents a fundamental synthetic challenge and has motivated considerable efforts.Herein we report a modified CVD approach with controllable reverse flow for rapid growth of large domain single crystals of monolayer TMDs.With the use of reverse flow to precisely control the chemical vapor supply in the thermal CVD process,we can effectively prevent undesired nucleation before reaching optimum growth temperature and enable rapid nucleation and growth of monolayer TMD single crystals at a high temperature that is difficult to attain with use of a typical thermal CVD process.We show that monolayer single crystals of 450μm lateral size can be prepared in 10 s,with the highest lateral growth rate up to 45μm/s.Electronic characterization shows that the resulting monolayer WSe2 material exhibits excellent electronic properties with carrier mobility up to 90 cm^2 V^-1 s^-1,comparable to that of the best exfoliated monolayers.Our study provides a robust pathway for rapid growth of high-quality TMD single crystals. | Zhengwei Zhang Peng Chen Xiangdong Yang Yuan Liu Huifang Ma Jia Li Bei Zhao Jun Luo Xidong Duan Xiangfeng Duan | 2020 | National Science Review2020,7,4: | 4 |
| 4 | A Silicon Monoxide Lithium-Ion Battery Anode with Ultrahigh Areal Capacity显示文摘Silicon monoxide(SiO)is an attractive anode material for next-generation lithium-ion batteries for its ultra-high theoretical capacity of 2680 mAh g−1.The studies to date have been limited to electrodes with a rela-tively low mass loading(<3.5 mg cm^(−2)),which has seriously restricted the areal capacity and its potential in practical devices.Maximizing areal capacity with such high-capacity materials is critical for capitalizing their potential in practi-cal technologies.Herein,we report a monolithic three-dimensional(3D)large-sheet holey gra-phene framework/SiO(LHGF/SiO)composite for high-mass-loading electrode.By specifically using large-sheet holey graphene building blocks,we construct LHGF with super-elasticity and exceptional mechanical robustness,which is essential for accommodating the large volume change of SiO and ensuring the structure integrity even at ultrahigh mass loading.Additionally,the 3D porous graphene network structure in LHGF ensures excellent electron and ion transport.By systematically tailoring microstructure design,we show the LHGF/SiO anode with a mass loading of 44 mg cm^(−2)delivers a high areal capacity of 35.4 mAh cm^(−2)at a current of 8.8 mA cm^(−2)and retains a capacity of 10.6 mAh cm^(−2)at 17.6 mA cm^(−2),greatly exceeding those of the state-of-the-art commercial or research devices.Furthermore,we show an LHGF/SiO anode with an ultra-high mass loading of 94 mg cm^(−2)delivers an unprecedented areal capacity up to 140.8 mAh cm^(−2).The achievement of such high areal capacities marks a critical step toward realizing the full potential of high-capacity alloy-type electrode materials in practical lithium-ion batteries. | Jiang Zhong Tao Wang Lei Wang Lele Peng Shubin Fu Meng Zhang Jinhui Cao Xiang Xu Junfei Liang Huilong Fei Xidong Duan Bingan Lu Yiliu Wang Jian Zhu Xiangfeng Duan | 2022 | Nano-Micro Letters2022,14,3: | 4 |
| 5 | A survey analysis of heavy metals bio-accumulation in internal organs of sea shell animals affected by the sustainable pollution of antifouling paints used for ships anchored at some domestic maritime spaces显示文摘Some samples of sea shell animals stuck and multiplied on the bottom (beneath the seawater) coated with antifouling paints were collected at some domestic maritime spaces, and the content of heavy metals was detected through Inductively Coupled Plasma-Mass Spectroscopy. Meanwhile, comparison with sea shell animals was made on market for edible use. It shows that the content of heavy metals in internal organs of these marine animals is very high due to the large amount of copper and zinc con- tained in the antifouling paints, and this also does severely harm to sea environment and ecology. To study and develop the novel antifouling paints without copper(I) oxide is an imperative task which brooks no delay. | WANG JunLian WANG FengQi YU Jie ZHUANG yan ZHOU XiangFeng ZHANG XiaoBin PENG BiXian | 2008 | Chinese Science Bulletin2008,53,16: | 3 |
| 6 | Epidemiological Investigation of an Inhalational Anthrax Patient Traveling for Medical Treatment in Beijing Municipality,China,August 2021显示文摘Summary What is already known about this topic?Inhalational anthrax,also known as pulmonary anthrax,is an infectious disease caused by Bacillus anthracis.The patients are usually infected by inhaling aerosolized B.anthracis spores from dead animals or animal products.Compared to cutaneous anthrax,inhalational anthrax is rare and deadly and few cases in China were reported.What is added by this report?This report covers all information of clinical features,laboratory testing,and epidemiological characteristics as well as exposure history of a recent primary inhalational anthrax patient who was seeking medical treatment in Beijing Municipality in August 2021.New laboratory techniques,including second-generation sequencing,polymerase chain reaction,and rapid test for serum antibody,played an important role in the process.What are the implications for public health practice?The information provided in this report,including the correct sample type,epidemiological investigation details,and application of the new diagnostic criteria of anthrax,could assist public health professionals in dealing with anthrax epidemics. | Changying Lin Xiangfeng Dou Daitao Zhang Yinqi Sun Huiqiang Han Chunzhi Chen Xiaojun Zhang Shuang Li Yanwei Chen Hongbin Zhang Bin Wang Zhichao Liang Xin Zhang Feng Wei Jiangli Wang Feng Liu Quanyi Wang Jian Shi Peng Yang | 2022 | China CDC weekly2022,4,1: | 3 |
| 7 | Studies on the synthesis,pungency and anti-biofouling performance of capsaicin analogues显示文摘Ten capsaicin analogues were synthesized and their pungency degrees were determined through Scoville Organoleptic Test.The relationship between the structure and pungency degree of these capsaicin analogues was discussed.Then four of these capsaicin analogues with higher pungency degree were picked out and added to anti-biofouling paints as repellents to study their anti-biofouling performance by shallow sea buoyant raft hung-plate experimentation.The results showed that capsaicin and dihydrocapsaicin exhibited equally good anti-biofouling performance while nordihydrocapsaicin and N-vanillylnonanamide had poor anti-biofouling performance.Experimental results also showed that the paints with only 0.1% capsaicin or dihydrocapsaicin as repellent without any other biocides had also exhibited good anti-biofouling performance,which provided a new idea for developing novel,more environment-friendly and Cu2O-free antifouling paints. | PENG BiXian WANG JunLian PENG ZhengHong ZHOU ShengZe WANG FengQi JI YongLiang YE ZhangJi ZHOU XiangFeng LIN Tong ZHANG XiaoBin | 2012 | Science China Chemistry2012,55,3: | 3 |
| 8 | Transcriptome Comparison of Susceptible and Resistant Wheat in Response to Powdery Mildew Infection显示文摘Powdery mildew(Pm) caused by the infection of Blumeria graminis f.sp.tritici(Bgt) is a worldwide crop disease resulting in significant loss of wheat yield.To profile the genes and pathways responding to the Bgt infection,here,using Affymetrix wheat microarrays,we compared the leaf transcriptomes before and after Bgt inoculation in two wheat genotypes,a Pm-susceptible cultivar Jingdong 8(S) and its near-isogenic line(R) carrying a single Pm resistant gene Pm30.Our analysis showed that the original gene expression status in the S and R genotypes of wheat was almost identical before Bgt inoculation,since only 60 genes exhibited differential expression by P = 0.01 cutoff.However,12 h after Bgt inoculation,3014 and 2800 genes in the S and R genotype,respectively,responded to infection.A wide range of pathways were involved,including cell wall fortification,flavonoid biosynthesis and metabolic processes.Furthermore,for the first time,we show that sense-antisense pair genes might be participants in wheat-powdery mildew interaction.In addition,the results of qRT-PCR analysis on several candidate genes were consistent with the microarray data in their expression patterns.In summary,this study reveals leaf transcriptome changes before and after powdery mildew infection in wheat near-isogenic lines,suggesting that powdery mildew resistance is a highly complex systematic response involving a large amount of gene regulation. | Mingming Xin Xiangfeng Wang Huiru Peng Yingyin Yao Chaojie Xie Yao Han ZhongfuNi Qixin Sun | 2012 | Genomics, Proteomics & Bioinformatics2012,10,2: | 3 |
| 9 | Direct van der Waals epitaxial growth of 1D/2D Sb2Se3/WS2 mixed-dimensional p-n heterojunctions显示文摘The mixed-dimensional integration of two-dimensional (2D) materials with non-2D materials can give rise to prominent advances in performance or function.To date,the mixed-dimensional one-dimensional (1D)/2D heterostructures have been fabricated using various physical assembly approaches.However,direct epitaxial growth method which has notable advantages in preparing large-scale products and obtaining perfect interfaces is rarely investigated.Herein,we demonstrate for the first time the direct synthesis of the 1D/2D mixed-dimensional heterostructures by sequential vapor-phase growth of Sb2Se3 nanowires on WS2 monolayers.X-ray diffraction (XRD) pattern and Raman spectrum confirm the composition of the Sb2Se3/NS2 heterostructures.Transmission electron microscope (TEM) measurement demonstrates high quality of the heterostructures.Electrical transport characterization reveals that Sb2Se3 nanowire exhibits p-type characteristic and that WS2 monolayer exhibits n-type behavior,and that the p-n diode from 1D/2D mixed-dimensional Sb2Se3/WS2 heterostructure possesses obvious current rectification behavior.Optoelectronic measurements of the heterostructures show apparent photovoltaic response with an open-circuit voltage of 0.19 V,photoresponsivity of 1.51 A/W (Vds =5 V) and fast response time of less than 8 ms.The van der Waals epitaxial growth mode of Sb2Se3 nanowires on WS2 monolayers is verified by stripping the Sb2Se3 nanowire from the heterostructures using tape.Together,the direct van der Waals epitaxy opens a facile pathway to 1D/2D mixed-dimensional heterostructures for functional electronic and optoelectronic devices. | Guangzhuang Sun Bo Li Jia Li Zhengwei Zhang Huifang Ma Peng Chen Bei Zhao Ruixia Wu Weiqi Dang Xiangdong Yang Xuwan Tang Chen Dai Ziwei Huang Yuan Liu Xidong Duan Xiangfeng Duan | 2019 | Nano Research2019,12,5: | 2 |
| 10 | Coupling magnetic particles with flocculants to enhance demulsification and separation of waste cutting emulsion for engineering applications显示文摘Magnetic particles were coupled with a flocculant to enhance the demulsification and separation of waste cutting emulsions.The optimal magnetic particle size and critical magnetic field conditions were investigated to achieve large-scale engineering application of magnetic demulsification separation for waste cutting emulsion treatment.The micro-scale magnetic particles were found to show comparable effects to nano-scale magnetic particles on enhancing the demulsification and separation of cutting emulsions,which are beneficial for broadening the selectivity of low-cost magnetic particles.The critical magnetic separation region was determined to be an area 40 mm from the magnetic field source.Compared to the flocculant demulsification,the magnetic demulsification separation exhibited a significant advantage in accelerating flocs-water separation by decreasing the separation time of flocs from 180-240 min to less than 15 min,compressing the flocs by reducing the floc volume ratio from 60%-90%to lower than 20%,and showing excellent adaptability to the variable properties of waste cutting emulsions.Coupled with the design of the magnetic disk separator,continuous demulsification separation of the waste cutting emulsion was achieved at 1.0 t/hr for at least 10 hr to obtain clear effluent with 81%chemical oxygen demand removal and 89%turbidity reduction.This study demonstrates the feasibility of applying magnetic demulsification separation to large-scale continuous treatment of waste emulsion.Moreover,it addresses the flocs-water separation problems that occur in practical flocculant demulsification engineering applications. | Yongjiao Xiong Baoqiang Wu Xiangfeng Huang Chenlu Li Bin Lu Jia Liu Lijun Lu Shiyang Li Kaiming Peng | 2021 | Journal of Environmental Sciences2021,33,7: | 2 |
| 11 | The promises, challenges and pathways to room-temperature sodium-sulfur batteries显示文摘Room-temperature sodium-sulfur batteries(RT-Na-S batteries) are attractive for large-scale energy storage applications owing to their high storage capacity as well as the rich abundance and low cost of the materials.Unfortunately, their practical application is hampered by severe challenges, such as low conductivity of sulfur and its reduced products, volume expansion, polysulfide shuttling effect and Na dendrite formation,which can lead to rapid capacity fading. The review discusses the Na-S-energy-storage chemistry,highlighting its promise, key challenges and potential strategies for large-scale energy storage systems.Specifically, we review the electrochemical principles and the current technical challenges of RT-Na-S batteries, and discuss the strategies to address these obstacles. In particular, we give a comprehensive review of recent progresses in cathodes, anodes, electrolytes, separators and cell configurations, and provide a forward-looking perspective on strategies toward robust high-energy-density RT-Na-S batteries. | Lei Wang Tao Wang Lele Peng Yiliu Wang Meng Zhang Jian Zhou Maoxin Chen Jinhui Cao Huilong Fei Xidong Duan Jian Zhu Xiangfeng Duan | 2022 | National Science Review2022,9,3: | 2 |

| 13 | Multivalent manganese oxides with high electrocatalytic activity for oxygen reduction reaction显示文摘A noble-metal-free catalyst based on both Mn3O4 and MnO was prepared by using the dielectric barrier discharge technique at moderate temperature.The prepared catalyst shows a higher electrocatalytic activity towards the oxygen reduction reaction than the catalyst prepared by using the traditional calcination process.The enhanced activity could be due to the coexistence of manganese ions with different valences,the higher oxygen adsorption capacity,and the suppressed aggregation of the catalyst nanoparticles at moderate temperature.The present work would open a new way to prepare low-cost and noble-metal-free catalysts at moderate temperature for more efficient electrocatalysis. | Xiangfeng Peng Zhenhai Wang Zhao Wang Yunxiang Pan | 2018 | Frontiers of Chemical Science and Engineering2018,12,4: | 1 |

| 16 | Oxygen Vacancy-Enriched FeOx Nanoparticle Electrocatalyst for the Oxygen Reduction Reaction显示文摘FeOx electrocatalysts for the oxygen reduction reaction were prepared via one-step synthesis using electron impact with cold plasma as the electron source.Given the low operation temperature,FeOx by plasma technology showed a smaller particle size than that prepared via conventional calcination.Notably,electron impact produced more oxygen vacancies and a larger surface area on FeOx,which increased active sites and electronic conductivity,than plasma.Electrochemical investigations indicated that FeOx prepared by plasma exhibited remarkable oxygen reduction reaction activity toward the four-electron electrochemical reduction of oxygen.The results demonstrated that this facile fabrication method is a promising route for developing cost-eff ective and high-performance catalysts to be used in electrochemical applications. | Luyu Ji Xiangfeng Peng Zhao Wang | 2020 | Transactions of Tianjin University2020,26,5: | 1 |

| 19 | Macroscopic assembled graphene nanofilms based room temperature ultrafast mid-infrared photodetectors显示文摘Graphene with linear energy dispersion and weak electron-phonon interaction is highly anticipated to harvest hot electrons in a broad wavelength range.However,the limited absorption and serious backscattering of hot-electrons result in inadequate quantum yields,especially in the mid-infrared range.Here,we report a macroscopic assembled graphene(nMAG)nanofilm/silicon heterojunction for ultrafast mid-infrared photodetection.The assembled Schottky diode works in 1.5-4.0μm at room temperature with fast response(20-30 ns,rising time,4 mm2 window)and high detectivity(1.61011 to 1.9109 Jones from 1.5 to 4.0μm)under the pulsed laser,outperforming single-layer-graphene/silicon photodetectors by 2-8 orders.These performances are attributed to the greatly enhanced photo-thermionic effect of electrons in nMAG due to its high light absorption(~40%),long carrier relaxation time(~20 ps),low work function(4.52 eV),and suppressed carrier number fluctuation.The nMAG provides a long-range platform to understand the hot-carrier dynamics in bulk 2D materials,leading to broadband and ultrafast MIR active imaging devices at room temperature. | Li Peng Lixiang Liu Sichao Du Srikrishna Chanakya Bodepudi Lingfei Li Wei Liu Runchen Lai Xiaoxue Cao Wenzhang Fang Yingjun Liu Xinyu Liu Jianhang Lv Muhammad Abid Junxue Liu Shengye Jin Kaifeng Wu Miao-Ling Lin Xin Cong Ping-Heng Tan Haiming Zhu Qihua Xiong Xiaomu Wang Weida Hu Xiangfeng Duan Bin Yu Zhen Xu Yang Xu Chao Gao | 2022 | InfoMat2022,4,6: | 1 |
| 20 | Safety and immunogenicity of a mosaic vaccine booster against Omicron and other SARS-CoV-2 variants:a randomized phase 2 trial显示文摘An ongoing randomized,double-blind,controlled phase 2 trial was conducted to evaluate the safety and immunogenicity of a mosaic-type recombinant vaccine candidate,named NVSI-06-09,as a booster dose in subjects aged 18 years and older from the United Arab Emirates(UAE),who had administered two or three doses of inactivated vaccine BBIBP-CorV at least 6 months prior to enrollment.The participants were randomly assigned with 1:1 to receive a booster dose of NVSI-06-09 or BBIBP-CorV.The primary outcomes were immunogenicity and safety against severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)Omicron variant,and the exploratory outcome was cross-immunogenicity against other circulating strains.Between May 25 and 30,2022,516 adults received booster vaccination with 260 in NVSI-06-09 group and 256 in BBIBP-CorV group.Interim results showed a similar safety profile between two booster groups,with low incidence of adverse reactions of grade 1 or 2.For immunogenicity,by day 14 post-booster,the fold rises in neutralizing antibody geometric mean titers(GMTs)from baseline elicited by NVSI-06-09 were remarkably higher than those by BBIBP-CorV against the prototype strain(19.67 vs 4.47-fold),Omicron BA.1.1(42.35 vs 3.78-fold),BA.2(25.09 vs 2.91-fold),BA.4(22.42 vs 2.69-fold),and BA.5 variants(27.06 vs 4.73-fold).Similarly,the neutralizing GMTs boosted by NVSI-06-09 against Beta and Delta variants were also 6.60-fold and 7.17-fold higher than those by BBIBP-CorV.Our findings indicated that a booster dose of NVSI-06-09 was well-tolerated and elicited broad-spectrum neutralizing responses against divergent SARS-CoV-2 variants,including Omicron and its sub-lineages. | Nawal Al Kaabi Yun Kai Yang Yu Liang Ke Xu Xue Feng Zhang Yun Kang Yu Qin Jin Jun Wei Hou Jing Zhang Tian Yang Salah Hussein Mohamed Saif ElDein Ze Hua Lei Hao Zhang Shuai Shao Zhao Ming Liu Ning Liu Xiang Zheng Ji Guo Su Sen Sen Yang Xiangfeng Cong Yao Tan Wenwen Lei Xue Jun Gao Zhiwei Jiang Hui Wang Meng Li Hanadi Mekki Mekki Walid Zaher Sally Mahmoud Xue Zhang Chang Qu Dan Ying Liu Jing Zhang Mengjie Yang Islam Eltantawy Peng Xiao Fu Jie Shen Jin Juan Wu Zi Bo Han Li Fang Du Fang Tang Shi Chen Zhi Jing Ma Fan Zheng Ya Nan Hou Xin Yu Li Xin Li Zhao Nian Wang Jin Liang Yin Xiao Yan Mao Jin Zhang Liang Qu Yun Tao Zhang Xiao Ming Yang Guizhen Wu Qi Ming Li | 2023 | Signal Transduction and Targeted Therapy2023,8,2: | 0 |
