1Differences of the oxidation process and secondary organic aerosol formation at low and high precursor concentrations显示文摘Current atmospheric quality models usually underestimate the level of ambient secondary organic aerosol(SOA), one of the possible reasons is that the precursors at different concentrations may undergo different oxidation processes and further affect SOA formation. Therefore, there is a need to perform more chamber studies to disclose the influence. In this work, SOA formation over a wide range of initial precursor concentrations(tens of ppb to hundreds of ppb levels) was investigated in a 30 m3 indoor smog chamber,and mainly through the analysis of multiple generations of VOCs detected from HR-To FPTRMS to expound the difference in the oxidation process between low and high precursor concentrations. Compared to high initial concentrations, gas-phase intermediates formed at low concentrations had a higher intensity by about one order of magnitude, and the lowvolatility compounds also had a higher formation potential due to the competition between semi-volatile intermediates and precursors with oxidants. In addition, the formed SOA was more oxidized with higher f44 value(0.14 ± 0.02) and more relevant to real atmosphere than that formed at high concentrations. This work should help to deeply understand SOA formation and improve the performance of air quality models for SOA simulation.Tianzeng Chen Yongchun Liu Biwu Chu Changgeng Liu Jun Liu Yanli Ge Qingxin Ma Jinzhu Ma Hong He 2019Journal of Environmental Sciences2019,31,5:4
2Efficient genotype-independent cotton genetic transformation and genome editing显示文摘Cotton(Gossypium spp.)is one of the most important fiber crops worldwide.In the last two decades,transgenesis and genome editing have played important roles in cotton improvement.However,genotype dependence is one of the key bottlenecks in generating transgenic and gene-edited cotton plants through either particle bombardment or Agrobacterium-mediated transformation.Here,we developed a shoot apical meristem(SAM)cell-mediated transformation system(SAMT)that allowed the transformation of recalcitrant cotton genotypes including widely grown upland cotton(Gossypium hirsutum),Sea island cotton(Gossypium barbadense),and Asiatic cotton(Gossypium arboreum).Through SAMT,we successfully introduced two foreign genes,GFP and RUBY,into SAM cells of some recalcitrant cotton genotypes.Within 2–3 months,transgenic adventitious shoots generated from the axillary meristem zone could be recovered and grown into whole cotton plants.The GFP fluorescent signal and betalain accumulation could be observed in various tissues in GFP-and RUBY-positive plants,as well as in their progenies,indicating that the transgenes were stably integrated into the genome and transmitted to the next generation.Furthermore,using SAMT,we successfully generated edited cotton plants with inheritable targeted mutagenesis in the GhPGF and GhRCD1 genes through CRISPR/Cas9-mediated genome editing.In summary,the established SAMT transformation system here in this study bypasses the embryogenesis process during tissue culture in a conventional transformation procedure and significantly accelerates the generation of transgenic and gene-edited plants for genetic improvement of recalcitrant cotton varieties.Xiaoyang Ge Jieting Xu Zhaoen Yang Xiaofeng Yang Ye Wang Yanli Chen Peng Wang Fuguang Li 2023Journal of Integrative Plant Biology2023,65,4:3
3Anomalous in-plane magnetoresistance of electron-doped cuprate La_(2.x)Ce_xCuO_(4±δ)显示文摘We report systematic in-plane magnetoresistance measurements on the electron-doped cuprate La_(2.x)Ce_xCuO_(4±δ) thin films as a function of Ce doping and oxygen content in the magnetic field up to 14 T. A crossover from negative to positive magnetoresistance occurs between the doping level x = 0.07 and 0.08. Above x = 0.08, the positive magnetoresistance effect appears, and is almost indiscernible at x = 0.15. By tuning the oxygen content, the as-grown samples show negative magnetoresistance effect, whereas the optimally annealed ones display positive magnetoresistance effect at the doping level x = 0.15. Intriguingly, a linear-field dependence of in-plane magnetoresistance is observed at the underdoping level x = 0.06, the optimal doping level x = 0.1 and slightly overdoping level x = 0.11. These anomalies of in-plane magnetoresistance may be related to the intrinsic inhomogeneity in the cuprates, which is discussed in the framework of network model.Heshan Yu Ge He Yanli Jia Xu Zhang Jie Yuan Beiyi Zhu A.Kusmartseva F.V.Kusmartsev Kui Jin 2017Science China(Physics,Mechanics & Astronomy)2017,60,9:1
4Preparation of Ag@CuFe_(2)O_(4)@TiO_(2) nanocomposite films and its performance of photoelectrochemical cathodic protection显示文摘A Ag@CuFe_(2)O_(4)@TiO_(2) nanocomposite film with high performance of photogenerated cathodic protection was prepared by hydrothermal and photoreduction methods.The results showed that when the CuFe_(2)O_(4) hydrothermal reaction time was 6 h and the AgNO_(3) concentration was 0.1 M,the Ag@CuFe_(2)O_(4)@TiO_(2) nanocomposite material performed the best cathodic protection capability for 304 stainless steel(304SS).In this case,the protective potential achieved-930 mV(versus SCE)associated with the photocurrent density of 475μA/cm^(2),which was 14.8 times that of pure TiO_(2) nanowires.In the dark,the nanocomposite provided cathodic protection of up to 485 mV for 304SS.Due to the heterogeneous junctions at the two interfaces among the three kinds of nanocomposite materials,the build-in electric field was fabricated,which promoted the separation efficiency of photogenerated electrons and holes and effectively improved the photochemical cathodic protection of 304SS.Ning Wang Jing Wang Mengnan Liu Chengyue Ge Baorong Hou Yanli Ning Yiteng Hu 2022Journal of Materials Science & Technology2022,,5:1

7Hexagonal boron nitride/poly(vinyl butyral)composite coatings for corrosion protection of copper显示文摘Hexagonal boron nitride(h-BN)fillers are incorporated into poly(vinyl butyral)(PVB)coatings to improve the corrosion protection performance of copper.It has been revealed that the h-BN fillers exhibit an excellent dispersiblility in PVB coating due to the non-covalent interactions between h-BN fillers and the PVB molecules.Electrochemical characterization reveals that the corrosion resistance of the BN-reinforced PVB(BN-P)coating is 5-6 orders of magnitude higher than that of the pristine PVB coating.Photographs and metallography show that the copper substrate beneath the BN-P coating does not suffer from corrosion after immersion for 2 months,indicating that the BN-P coating can provide a long-term protective barrier for the underlying copper substrate.Loading 0-0.25 g h-BN fillers in 2.0 g PVB,the corrosion protection performance increases with increasing the loading of h-BN fillers.The scratch test results suggest that h-BN fillers do not accelerate copper corrosion when the BN-P coating is damaged.Jing Wang Ning Wang Mengnan Liu Chengyue Ge Baorong Hou Guichang Liu Wen Sun Yiteng Hu Yanli Ning 2022Journal of Materials Science & Technology2022,,1:1

9Study on the reaction of 3-methyl-2-butenal and 3-methylbutanal with Cl atoms: kinetics and reaction mechanism显示文摘The reaction of Cl atoms with two C5aldehydes(3-methyl-2-butenal and 3-methylbutanal)were investigated by proton-transfer-reaction mass spectrum(PTR-MS)using smog chamber at 298±1 K and 760 Torr.A relative rate method was used to determine the rate constants of the title reactions with m-xylene and trans-2-butene as reference compounds:(3.04±0.18)×10^(-10)and(2.07±0.14)×10^(-10)cm^(3)/(molecule·sec)for 3-methyl-2-butenal and 3-methylbutanal,respectively.Additionally,the gas-phase products were also identified by PTR-MS,and the possible reaction mechanisms were proposed basing on the identified products.The detected gas-phase products are similar for two C5aldehydes reactions,mainly including small molecules of aldehydes,ketones and chlorinated aldehyde compounds.The atmospheric lifetimes(τ)calculated for 3-methyl-2-butenal(τ=7.0 hr,marine boundary layer(MBL))and 3-methylbutanal(τ=10.3 hr,MBL)according to the obtained rate constants.The results indicate that Cl atoms at MBL are competitive with OH radicals for the degradation contribution of C5aldehyde compounds.Bo Shi Weigang Wang Cici Fan Yuchan Zhang Zheng Sun Yanli Zeng Maofa Ge 2022Journal of Environmental Sciences2022,34,6:0
10Effects of ultrasonic treatment on dithiothreitol(DTT) assay measurements for carbon materials显示文摘The dithiothreitol(DTT)assay is the most commonly used method to quantify the oxidative potential of fine particles.However,the reported DTT decay rates of carbon black(CB)materials vary greatly among different researchers.This might have resulted from either the intrinsic toxicity of CB or the unsuitability of the DTT assay protocol for CB particles.In the current study,the protocol of the DTT assay for CB materials has been carefully evaluated.It was found that the dispersion degree of CB particles in water has a great influence on the DTT decay rate of CB materials.For CB particles(special black 4A(SB4A)and Printex U)and single-walled carbon nanotube tube(SWCNT),the DTT decay rate after sonication for 10 min became 4.2,4.6 and 1.7 times higher than that without sonication.The rate continued to grow as a function of ultrasound time up to 30 min of sonication.Although the concentration of soluble transition metals and surface oxygen-containing species such as carbonyls increased slightly with sonication,they had no significant effects on the measured DTT activity,while the increase in the dispersion degree of aggregates was found to play a vital role in the observed enhancement of the DTT decay rates for different CB materials.Based on our results,30 min of sonication is recommended for sample dispersion when measuring the DTT decay rate of CB materials.Haotian Jiang Yun Xie Yanli Ge Hong He Yongchun Liu 2019Journal of Environmental Sciences2019,31,10:0
11Causal Effect of Genetically Determined Blood Copper Concentrations on Multiple Diseases: A Mendelian Randomization and Phenome-Wide Association Study显示文摘Exposures to copper have become a health concern.We aim to explore the broad clinical effects of blood copper concentrations.A total of 376,346 Caucasian subjects were enrolled.We performed a Mendelian randomization and phenome-wide association study(MR-PheWAS)to evaluate the causal association between copper and a wide range of outcomes in UK Biobank,and we constructed a protein-protein interaction network.We found association between blood copper concentrations and five diseases in the overall population and nine diseases in male.MR analysis implicated a causal role of blood copper in five diseases(overall population),including prostate cancer(OR=0.87,95%CI 0.77-0.98),malignant and unknown neoplasms of the brain and nervous system(OR=0.58,95%CI 0.38-0.89),and hypertension(OR=0.94,95%CI 0.90-0.98),essential hypertension(OR=0.94,95%CI 0.90-0.98)and cancer of brain and nervous system(OR=0.63,95%CI 0.41-0.98).For male,except for dysphagia being newly associated with blood copper(OR=1.39,95%CI 1.18-1.63),other MR results were consistent with the overall population.In addition,the PPI network showed possible relationship between blood copper and four outcomes,namely brain cancer,prostate cancer,hypertension,and dysphagia.Blood copper may have causal association with prostate cancer,malignant and unknown neoplasms of the brain and nervous system,hypertension,and dysphagia.Considering that copper is modifiable,exploring whether regulation of copper levels can be used to optimize health outcomes might have public health importance.Xiuming Feng Wenjun Yang Lulu Huang Hong Cheng Xiaoting Ge Gaohui Zan Yanli Tan Lili Xiao Chaoqun Liu Xing Chen Zengnan Mo Longman Li Xiaobo Yang 2022Phenomics2022,2,4:0
12“In-N-out” design enabling high-content triethyl phosphate-based non-flammable and high-conductivity electrolytes for lithium-ion batteries显示文摘Safety issues related to flammable electrolytes in lithium-ion batteries(LIBs) remain a major challenge for their extended applications.The use of non-flammable phosphate-based electrolytes has proved the validity in inhibiting the combustion of LIBs.However,the strong interaction between Li^(+) and phosphate leads to a dominant solid electrolyte interphase(SEI) with limited electronic shielding,resulting in the poor Li^(+) intercalation at the graphite(Gr) anode when using high-phosphate-content electrolytes.To mitigate this issue and improve Li^(+) insertion,we propose an “In-N-Out” strategy to render phosphates “noncoordinative”.By employing a combination of strongly polar solvents for a “block effect” and weakly polar solvents for a “drag effect”,we reduce the Li^(+)–phosphate interaction.As a result,phosphates remain in the electrolyte phase(“In”),minimizing their impact on the incompatibility with the Gr electrode(“Out”).We have developed a non-flammable electrolyte with high triethyl phosphate(TEP) content(>60 wt.%),demonstrating the excellent ion conductivity(5.94 mS cm^(-1) at 30 ℃) and reversible Li^(+) intercalation at a standard concentration(~1 mol L^(-1)).This approach enables the manipulation of multiple electrolyte functions and holds the promise for the development of safe electrochemical energy storage systems using non-flammable electrolytes.Mengchuang Liu Fenfen Ma Zicheng Ge Ziqi Zeng Qiang Wu Hui Yan Yuanke Wu Sheng Lei Yanli Zhu Shijie Cheng Jia Xie 2024Science China Chemistry2024,67,2:0
