| 1 | In situ grown Fe_(3)O_(4)particle on stainless steel:A highly efficient electrocatalyst for nitrate reduction to ammonia显示文摘NH_(3)is an essential feedstock for fertilizer synthesis.Industry-scale NH_(3)synthesis mostly relies on the Haber-Bosch method,however,which suffers from massive CO_(2) emission and high energy consumption.Electrocatalytic NO_(3)-reduction is an attractive substitute to the Haber-Bosch method for synthesizing NH_(3)under mild conditions.As this reaction will produce a variety of products,it highly desires efficient and selective electrocatalyst for NH_(3)generation.Here,we report in situ grown Fe_(3)O_(4)particle on stainless steel(Fe_(3)O_(4)/SS)as a high-efficiency electrocatalyst for NO_(3)^(-)reduction to NH_(3).In 0.1 M NaOH with 0.1 M NaNO_(3),such Fe_(3)O_(4)/SS reaches a remarkable Faradaic efficiency of 91.5%and a high NH_(3)yield of 10,145μg·h^(-1)·cm^(-2)at-0.5 V vs.reversible hydrogen electrode(RHE).Furthermore,it owns robust structural and electrochemical stability.This work provides useful guidelines to expand the scope of metallic oxide electrocatalysts for NH_(3)synthesis.The catalytic mechanism is uncovered and discussed further by theoretical calculations. | Xiaoya Fan Lisi Xie Jie Liang Yuchun Ren Longcheng Zhang Luchao Yue Tingshuai Li Yonglan Luo Na Li Bo Tang Yang Liu Shuyan Gao Abdulmohsen Ali Alshehri Qian Liu Qingquan Kong Xuping Sun | 2022 | Nano Research2022,15,4: | 7 |
| 2 | Influence of 3A molecular sieve on tetrahydrofuran (THF) hydrate formation显示文摘Visual observation of the THF hydrate formation process in the presence of a 3A molecular sieve has been made at normal atmosphere and below a temperature of zero by microscopy. The results indicate that a 3A molecular sieve can induce the nucleation of the THF hydrate and promote the THF hydrate growth. With the existence of a 3A molecular sieve, the growth rate of THF hydrate is between 0.01 and 0.05 μm/s. In comparison with the system without any 3A molecular sieve, the growth rate increases about 4 nm/s. After the THF hydrate grows into megacryst, the crystals will recombine and partially change under the same condition. | ZANG XiaoYa FAN ShuanShi LIANG DeQing LI DongLiang CHEN GuangJin | 2008 | Science China Chemistry2008,51,9: | 6 |
| 3 | Tandem catalysis in electrochemical CO_(2) reduction reaction显示文摘Electrochemical CO_(2) reduction reaction(CO_(2)RR)is an attractive pathway for closing the anthropogenic carbon cycle and storing intermittent renewable energy by converting CO_(2) to valuable chemicals and fuels.The production of highly reduced carbon compounds beyond CO and formate,such as hydrocarbon and oxygenate products with higher energy density,is particularly desirable for practical applications.However,the productivity towards highly reduced chemicals is typically limited by high overpotential and poor selectivity due to the multiple electron-proton transfer steps.Tandem catalysis,which is extensively utilized by nature for producing biological macromolecules with multiple enzymes via coupled reaction steps,represents a promising strategy for enhancing the CO_(2)RR performance.Improving the efficiency of CO_(2)RR via tandem catalysis has recently emerged as an exciting research frontier and achieved significant advances.Here we describe the general principles and also considerations for designing tandem catalysis for CO_(2)RR.Recent advances in constructing tandem catalysts,mainly including bimetallic alloy nanostructures,bimetallic heterostructures,bimetallic core-shell nanostructures,bimetallic mixture catalysts,metal-metal organic framework(MOF)and metal-metallic complexes,metal-nonmetal hybrid nanomaterials and copper-free hybrid nanomaterials for boosting the CO_(2)RR performance are systematically summarized.The study of tandem catalysis for CO_(2)RR is still at the early stage,and future research challenges and opportunities are also discussed. | Yating Zhu Xiaoya Cui Huiling Liu Zhenguo Guo Yanfeng Dang Zhanxi Fan Zhicheng Zhang Wenping Hu | 2021 | Nano Research2021,14,12: | 5 |
| 4 | Impact Analysis of Solar Irradiance Change on Precision Orbit Determination of Navigation Satellites显示文摘Solar radiation pressure is the main driving force and error source for precision orbit determination of navigation satellites.It is proportional to the solar irradiance,which is the'sun constant'.In regular calculation,the'solar constant'is regard as a constant.However,due to the existence of sunspots,flares,etc.,the solar constant is not fixed,the change in the year is about 1%.To investigate the variation of solar irradiance,we use interpolation and average segment modeling of total solar irradiance data of SORCE,establishing variance solar radiation pressure(VARSRP)model and average solar radiation pressure(AVESRP)model based on the built solar pressure model(SRPM)(constant model).According to observation data of global positioning system(GPS)and Beidou system(BDS)in 2015 and comparing the solar pressure acceleration of VARSRP,AVESRP and SRPM,the magnitude of change can reach 10-10 m/s^2.In addition,according to the satellite precise orbit determination,for GPS satellites,the results of VARSRP and AVESRP are slightly smaller than those of the SRPM model,and the improvement is between 0.1 to 0.5 mm.For geosynchronous orbit(GEO)satellites of BDS,The AVESRP and VARSRP have an improvement of 3.5 mm and 4.0 mm,respectively,based on overlapping arc,and SLR check results show the AVESRP model and the VARSRP model is improved by 2.3 mm and 3.5 mm,respectively.Moreover,the change of inclined geosynchronous orbit(IGSO)satellites and medium earth orbit(MEO)satellites is relatively small,and the improvement is smaller than 0.5 mm. | ZHANG Yan WANG Xiaoya XI Kewei SHAO Fan | 2019 | Transactions of Nanjing University of Aeronautics and Astronautics2019,36,6: | 4 |
| 5 | The complete reference genome for grapevine (Vitis vinifera L.) genetics and breeding显示文摘Grapevine is one of the most economically important crops worldwide.However,the previous versions of the grapevine reference genome tipically consist of thousands of fragments with missing centromeres and telomeres,limiting the accessibility of the repetitive sequences,the centromeric and telomeric regions,and the study of inheritance of important agronomic traits in these regions.Here,we assembled a telomere-to-telomere(T2T)gap-free reference genome for the cultivar PN40024 using PacBio HiFi long reads.The T2T reference genome(PN_T2T)is 69 Mb longer with 9018 more genes identified than the 12X.v0 version.We annotated 67%repetitive sequences,19 centromeres and 36 telomeres,and incorporated gene annotations of previous versions into the PN_T2T assembly.We detected a total of 377 gene clusters,which showed associations with complex traits,such as aroma and disease resistance.Even though PN40024 derives from nine generations of selfing,we still found nine genomic hotspots of heterozygous sites associated with biological processes,such as the oxidation–reduction process and protein phosphorylation.The fully annotated complete reference genome therefore constitutes an important resource for grapevine genetic studies and breeding programs. | Xiaoya Shi Shuo Cao Xu Wang Siyang Huang Yue Wang Zhongjie Liu Wenwen Liu Xiangpeng Leng Yanling Peng Nan Wang Yiwen Wang Zhiyao Ma Xiaodong Xu Fan Zhang Hui Xue Haixia Zhong Yi Wang Kekun Zhang Amandine Velt Komlan Avia Daniela Holtgräwe Jérôme Grimplet JoséTomás Matus Doreen Ware Xinyu Wu Haibo Wang Chonghuai Liu Yuling Fang Camille Rustenholz Zongming Cheng Hua Xiao Yongfeng Zhou | 2023 | Horticulture Research2023,10,5: | 3 |
| 6 | Rare earth complexes chemiluminescence catalyzed by gold nanoparticles for fast sensing of Tb^(3+)and Eu^(3+)显示文摘Developing multiplex sensing technique is of great significance for fast sample analysis.However,the broad emissions of most chemiluminescence(CL)luminophores make the multiplex CL analysis be difficult.In this work,a simple and sensitive CL analytical method has been developed for the simultaneous determination of Tb^(3+)and Eu^(3+)thanking to their narrow band emission.The technique was based on a mixed CL system of periodate(IO4-)-hydrogen peroxide(H_(2)O_(2))-rare earth complexes,in which the reactive oxygen species(ROSs)especially singlet oxygen(^(1)O_(2))can transfer its energy to the complex of Tb^(3+)/Eu^(3+)-ethylenediaminetetraacetic acid disodium salt(EDTA)and then produce the characteristic emissions of Tb^(3+)and Eu^(3+)without cross-interference.The further experiment found that the CL emissions of Tb^(3+)and Eu^(3+)could be catalyzed by the gold nanoparticles(AuNPs)via enhancing the yield of^(1)O_(2).The CL intensities of Tb^(3+)(at 490 nm)and Eu^(3+)(at 620 nm)increased linearly with concentration of Tb^(3+)and Eu^(3+).After the optimization of the CL sensing conditions,the limits of detection(LOD)were 5.0×10^(-9)mol/L and 8.0×10^(-7)mol/L for Tb^(3+)and Eu^(3+),respectively.Finally,the method has been applied for measuring the contents of Tb^(3+)and Eu^(3+)in leaching solution of mine sample and Tb^(3+)/Eu^(3+)-contained nanomaterials with satisfactory results.The present system provides a new CL technique for multiplex sensing with simplicity and high sensitivity. | Jiajia Yuan Xiaoya Fan Jiacheng Yang Xinfeng Zhang | 2023 | Chinese Chemical Letters2023,34,9: | 0 |
| 7 | Mixing states and secondary formation processes of organic nitrogen-containing single particles in Guangzhou,China显示文摘Organic nitrogen(ON)compounds play a significant role in the light absorption of brown carbon and the formation of organic aerosols,however,the mixing state,secondary formation processes,and influencing factors of ON compounds are still unclear.This paper reports on the mixing state of ON-containing particles based on measurements obtained using a highperformance single particle aerosol mass spectrometer in January 2020 in Guangzhou.The ON-containing particles accounted for 21% of the total detected single particles,and the particle count and number fraction of the ON-containing particles were two times higher at night than during the day.The prominent increase in the content of ON-containing particles with the enhancement of NO_xmainly occurred at night,and accompanied by high relative humidity and nitrate,which were associated with heterogeneous reactions between organics and gaseous NO_(x)and/or NO_(3)radical.The synchronous decreases in ON-containing particles and the mass absorption coefficient of water-soluble extracts at 365 nm in the afternoon may be associated with photo-bleaching of the ON species in the particles.In addition,the positive matrix factorization analysis found five factors dominated the formation processes of ON particles,and the nitrate factor(33%)mainly contributed to the production of ON particles at night.The results of this study provide unique insights into the mixing states and secondary formation processes of the ON-containing particles. | Lijun Yun Chunlei Cheng Suxia Yang Zaihua Wang Mei Li Qi En Zhong LiyuanMao Sulin Liu Xiaoya Cheng Duanying Chen Fan Yang Zhen Zhou | 2024 | Journal of Environmental Sciences2024,,4: | 0 |
| 8 | CeO_(2) nanoparticles with oxygen vacancies decorated N-doped carbon nanorods:A highly efficient catalyst for nitrate electroreduction to ammonia显示文摘Electrocatalytic nitrate reduction reaction(NO_(3)−RR)emerges as a highly efficient approach toward ammonia synthesis and degrading NO_(3)−contaminant.In our study,CeO_(2) nanoparticles with oxygen vacancies(VO)decorated N-doped carbon nanorods on graphite paper(CeO_(2)−x@NC/GP)were demonstrated as a highly efficient NO_(3)−RR electrocatalyst.The CeO_(2)−x@NC/GP catalyst manifests a significant NH_(3 )yield up to 712.75μmol·h^(−1)·cm^(−2) at−0.8 V vs.reversible hydrogen electrode(RHE)and remarkable Faradaic efficiency of 92.93%at−0.5 V vs.RHE under alkaline conditions,with excellent durability.Additionally,an assembled Zn-NO_(3)−battery with CeO_(2)−x@NC/GP as cathode accomplishes a high-power density of 3.44 mW·cm^(−2) and a large NH3 yield of 145.08μmol·h^(−1)·cm^(−2).Density functional theory results further expose the NO_(3)−reduction mechanism on CeO_(2)(111)surface with VO. | Zerong Li Zhiqin Deng Ling Ouyang Xiaoya Fan Longcheng Zhang Shengjun Sun Qian Liu Abdulmohsen Ali Alshehri Yonglan Luo Qingquan Kong Xuping Sun | 2022 | Nano Research2022,15,10: | 0 |
| 9 | The protective effects of Gastrodia elata Bl.decoction and Gastrodin on Acrylamide-induced DNA damage in mice显示文摘Acrylamide(AA)is ubiquitous in packaging materials,paints,cosmetics,food and drinking water.However,AA has obvious neurotoxicity,reproductive toxicity and carcinogenicity,which seriously endangers human health.As one of precious traditional Chinese medicines,Gastrodia elata Bl.has been mainly used to lower blood pressure and resist myocardial ischemia.However,the antioxidant activity of Gastrodia elata Bl.on AA-induced DNA damage has not been reported.We found that AA(25,30 and 50 mg/kg)could cause DNA damage and the damage was time/dose dependent.After AA administration,Tail moment,micronuclei formation rate,8-OHdG and MDA level were significantly increased and SOD activity was decreased.Gastrodia elata Bl.decoction,gastrodin and vitamin C could reduce AA-induced DNA damage by decreasing AA-induced increment of tail moment and micronuclei formation rate.What’s more,Gastrodia elata Bl.decoction,gastrodin and vitamin C could lower 8-OHdG and MDA level and improve SOD activity.In conclusion,our research showed that Gastrodia elata Bl.decoction and gastrodin had protective effects on AA-induced DNA damage,and the potential protective mechanism might be related to anti-oxidative stress. | Fan Wang Kuo Zhang Xiaoya Du Jingyu Yang Chunfu Wu | 2020 | Asian Journal of Traditional Medicines2020,15,6: | 0 |
| 10 | Fe-doped Co_(3)O_(4) nanowire strutted 3D pinewood-derived carbon: A highly selective electrocatalyst for ammonia production via nitrate reduction显示文摘Nitrate(NO_(3)^(-)),a nitrogen-containing pollutant,is prevalent in aqueous solutions,contributing to a range of environmental and health-related issues.The electrocatalytic reduction of NO_(3)^(-)holds promise as a sustainable approach to both eliminating NO_(3)^(-)and generating valuable ammonia(NH_(3)).Nevertheless,the reduction reaction of NO_(3)^(-)(NO_(3)^(-)RR),involving 8-electron transfer process,is intricate,necessitating highly efficient electrocatalysts to facilitate the conversion of NO_(3)^(-)to NH_(3).In this study,Fe-doped Co_(3)O_(4) nanowire strutted three-dimensional(3D)pinewood-derived carbon(Fe-Co_(3)O_(4)/PC)is proposed as a high-efficiency NO_(3)^(-)RR electrocatalyst for NH_(3) production.Operating within 0.1 M NaOH containing NO_(3)^(-),Fe-Co_(3)O_(4)/PC demonstrates exceptional performance,obtain an impressively large NH_(3) yield of 0.55 mmol·h^(-1)·cm^(-2) and an exceptionally high Faradaic efficiency of 96.5%at-0.5 V,superior to its Co_(3)O_(4)/PC counterpart(0.2 mmol·h^(-1)·cm^(-2),73.3%).Furthermore,the study delves into the reaction mechanism of Fe-Co_(3)O_(4) for NO_(3)^(-)RR through theoretical calculations. | Xuwei Liu Chaozhen Liu Xun He Zhengwei Cai Kai Dong Jun Li Xiaoya Fan Ting Xie Xiya Yang Yonglan Luo Dongdong Zheng Shengjun Sun Sulaiman Alfaifi Feng Gong Xuping Sun | 2024 | Nano Research2024,17,4: | 0 |
| 11 | Constraint Symbolization Method for Analog Layout Retargeting with Geometric Programming显示文摘To satisfy the requirements of complex and special analog layout constraints, a constraint symbolization method based on geometric programming for analog layout retargeting is presented in this paper. Our approach is to build symbolic template for layouts, then uses Geometric programming(GP) to achieve new technology design rules, implement device symmetry and matching constraints, and manage parasitics optimization. The GP,a class of non-linear optimization problem, can be transferred or fitted into a convex optimization problem. Therefore, a global optimum solution can be achieved. The symbolization method ensures the layout retargeting automatically. The efficiency and effectiveness of the proposed algorithm, as compared with the other existing methods, are demonstrated by a basic case-study example and a twostage Miller-compensated operational amplifier. | WANG Shaoxi FAN Xiaoya ZHANG Shengbing HAN Ru | 2014 | Chinese Journal of Electronics2014,23,1: | 0 |
| 12 | SOX2 heterozygous mutations cause multiple extraocular phenotypes in boys显示文摘To the Editor:The SRY-related high-mobility-group-box protein-2(SOX2)is most notably expressed in the eye,placodes,forebrain,and hypothalamus-pituitary and is involved in early embryonic development.[1]Loss-of-function mutations or deletions in SOX2 could lead to uni-or bi-lateral anophthalmia/microphthalmia(A/M)as well as other related disorders,such as anophthalmia/esophageal-genital syndrome.An increasing number of studies have found that SOX2 mutations can cause variable extraocular symptoms,including growth retardation,sensorineural hearing loss,mental retardation,no pubertal signs,and male genitourinary tract malformations(micropenis,cryptorchidism,and hypospadias).Indeed,cases with SOX2 pathogenic mutations but no or minor ocular symptoms have been reported less frequently.Several studies found that SOX2 heterozygous mutations cause typical signs of complete hypogonadism without major ocular malformations in men or women,such as isolated hypogonadotropic hypogonadism(HH),but no other HH pathogenic gene was identified.[2,3]Therefore,our study is the first to report the cases of three Chinese patients with SOX2 mutations referred due to micropenis and/or cryptorchidism combined with craniofacial deformities or intellectual disability. | Yi Wang Lijun Fan Xiaoya Ren Yanning Song Beibei Zhang Chunxiu Gong | 2022 | Chinese Medical Journal2022,,4: | 0 |
| 13 | Uncovering potential distinctive acoustic features of healing music显示文摘S Background Music therapy is a promising complementary intervention for addressing various mental health conditions.Despite evidence of the beneficial effects of music,the acoustic features that make music effective in therapeutic contexts remain elusive.Aims This study aimed to identify and validate distinctive acoustic features of healing music.Methods We constructed a healing music dataset(HMD)based on nominations from related professionals and extracted 370 acoustic features.Healing-distinctive acoustic features were identified as those that were(1)independent from genre within the HMD,(2)significantly different from music pieces in a classical music dataset(CMD)and(3)similar to pieces in a five-element music dataset(FEMD).We validated the identified features by comparing jazz pieces in the HMD with a jazz music dataset(JMD).We also examined the emotional properties of the features in a Chinese affective music system(CAMS).Results The HMD comprised 165 pieces.Among all the acoustic features,74.59%shared commonalities across genres,and 26.22%significantly differed between the HMD classical pieces and the CMD.The equivalence test showed that the HMD and FEMD did not differ significantly in 9.46%of the features.The potential healing-distinctive acoustic features were identified as the standard deviation of the roughness,mean and period entropy of the third coefficient of the mel-frequency cepstral coefficients.In a three-dimensional space defined by these features,HMD's jazz pieces could be distinguished from those of the JMD.These three features could significantly predict both subjective valence and arousal ratings in the CAMS.Conclusions The distinctive acoustic features of healing music that have been identified and validated in this study have implications for the development of artificial intelligence models for identifying therapeutic music,particularly in contexts where access to professional expertise may be limited.This study contributes to the growing body of research exploring the potential of digital technologies for healthcare interventions. | Yue Ding Jiaqi Jing Qihui Guo Jiajia Zhou Xinyao Cheng Xiaoya Chen Lihui Wang Yingying Tang Qing Fan | 2023 | General Psychiatry2023,36,6: | 0 |
