1Manifestations in Corrosion Prophase of Ultra-high Strength Steel 30CrMnSiNi2 A in Sodium Chloride Solutions显示文摘The corrosion behaviors of ultra-high strength steel 30CrMnSiNi2A in sodium chloride solution were studied by weight loss and electrochemical methods. The morphology of corrosion products was observed using scanning electron microscopy(SEM) and the composition was analyzed using an energy dispersive spectroscopy(EDS) and X-Ray diffraction(XRD). The experimental results showed that the corrosion came from pitting corrosion and the rust layer was composed of outer rust layer γ-FeOOH and inner rust layer Fe2O3 with a little β-FeOOH. The correlation between corrosion rate and test time accorded with exponential rule. The corrosion current measured by polarization methods was higher than that calculated by weight loss method after a long-time immersion, the main reason was that β-FeOOH and γ-Fe2O3 transformed by γ-FeOOH led to overestimating corrosion rate. The processes of corrosion prophase were obtained from XRD and EIS results. The corrosion product, Fe(OH)2 formed at the initial stage stayed at a non-steady state and then consequently transferred to γ-FeOOH, γ-Fe2O3 or β-FeOOH.刘建华 WEN Chen YU Mei LI Songmei WANG Ruiyang 2014Journal of Wuhan University of Technology(Materials Science)2014,29,2:3
2Excellent tribological properties of epoxy-Ti3C2 with three-dimensional nanosheets composites显示文摘As a widely used engineering polymer,epoxy resin has been successfully employed in high-performance components and setups.However,the poor thermal and friction properties of traditional epoxy resin greatly limit its application in many extreme environments.In this work,a new kind of epoxy-Ti3C2 with three-dimensional nanosheets(3DNS)composite which was designed by freeze-drying method showed up excellent thermal and friction properties.As a result,the coefficient of thermal expansion(CTE)of epoxy-Ti3C23DNS 3.0 composites was 41.9 ppm/K at 40℃,which was lower than that of the traditional epoxy resin(46.7 ppm/K),and the thermal conductivity(TC)was also improved from 0.176 to 0.262 W/(m-K).Meanwhile,epoxy-Ti3C23DNS 1.0 composites showed up the best friction property,with wear rate 76.3%lower than that of epoxy resin.This work is significant for the research of high-performance composite materials.Fanning MENG Zhenyu ZHANG Peili GAO Ruiyang KANG Yash BOYJOO Jinhong YU Tingting LIU 2021Friction2021,9,4:3
3InP quantum dots on g-C_(3)N_(4) nanosheets to promote molecular oxygen activation under visible light显示文摘Largely limited by the high dissociation energy of the O—O bond,the photocatalytic molecular oxygen activation is highly challenged,which re strains the application of photocatalytic oxidation technology for atmospheric pollutants removal.Herein,we design and fabricate the InP QDs/g-C_(3)N_(4) compounds.The introduction of InP QDs promotes the charge transfer within the interface resulting in the effective separation of photo-generated carriers.Furthermore,InP QDs greatly facilitates the activation of molecular oxygen and promote the formation of O_(2)·under visible-light illuminatio n.These conclusions are identified by experimental and calculation results.Hence,NO can be combined with the O_(2)·to form O—O—N—O intermediate to direct conversion into NO_(3).As a result,the NO removal ratio of g-C_(3)N_(4) has a one fold increase after InP QDs loaded and the generation of NO_(2) is effectively inhibited.This wo rk may provide a strategy to design highly efficient materials for molecular oxygen activation.Yuehan Cao Qian Zheng Zhiqiang Rao Ruiyang Zhang Zhanghui Xie Shan Yu Ying Zhou 2020Chinese Chemical Letters2020,31,10:3
4Enhanced tribological properties of aligned graphene-epoxy composites显示文摘The random distribution of graphene in epoxy matrix hinders the further applications of grapheneepoxy composites in the field of tribology.Hence,in order to fully utilize the anisotropic properties of graphene,highly aligned graphene-epoxy composites(AGEC)with horizontally oriented structure have been fabricated via an improved vacuum filtration freeze-drying method.The frictional tests results indicated that the wear rate of AGEC slowly increased from 5.19x10^(-6)mm^(3)/(N-m)to 2.87x10^(-5)mm^(3)/(N-m)with the increasing of the normal load from 2 to 10 N,whereas the friction coefficient(COF)remained a constant of 0.109.Compared to the neat epoxy and random graphene-epoxy composites(RGEC),the COF of AGEC was reduced by 87.5%and 71.2%,and the reduction of wear rate was 86.6%and 85.4%at most,respectively.Scanning electron microscope(SEM)observations illustrated that a compact graphene self-lubricant film was formed on the worn surface of AGEC,which enables AGEC to possess excellent tribological performance.Finally,in light of the excellent tribological properties of AGEC,this study highlights a pathway to expand the tribological applications of graphene-epoxy composites.Yuefeng DU Zhenyu ZHANG Dong WANG Lezhen ZHANG Junfeng CUI Yapeng CHEN Mingliang WU Ruiyang KANG Yunxiang LU Jinhong YU Nan JIANG 2022Friction2022,10,6:2

6Two chemical mutagens modulate the seed germination,growth,and phenotypic characteristics of Chinese fir(Cunninghamia lanceolata)显示文摘Chinese fir(Cunninghamia lanceolata(Lamb.)Hook),a fast-growing and economically important timber tree species in China,is widely used in construction,furniture,and paper manufacture but has a long breeding cycle.Chemical mutagens,such as ethyl methane sulfonate(EMS)and sodium azide(SA),are widely used in crops such as rice,wheat,cotton,soybean and sugarcane but their utility for tree breeding is unknown.In this study we examined the effects of EMS and S A on Chinese fir seed germination and growth.Chinese fir seeds were treated with the two chemical mutagens;were planted in Jiangle County,Fujian Province,China;and their heights were measured from 2011 to2017.The concentrations and durations of treatment with the two chemical mutagens were significantly associated with the Chinese fir seedling and mortality rates,as well as with the heights of trees from the seedling stage to 3 years old.We also generated 127 mutants with abnormal branches and reproductive growth.We report here the effects of two chemical mutagens on Chinese fir breeding;our data will contribute to knowledge of the utility of EMS and SA in forestry.Sen Cao Ruiyang Hu Xialei Wu Yuhan Sun Bo Wu Hongjing Duan Huazhong Lin Mingjing Wu Luming Fang Xiaolong Yu Wei Wu Yun Li 2021Journal of Forestry Research2021,32,5:0
73D magnetic field guided sunflower-like nanocatalytic active swarm targeting patients-derived organoids显示文摘Nanocatalytic medicine triggering in situ catalytic reactions has been considered as a promising strategy for tumor-selective therapeutics.However,the targeted distribution of nanocatalysts was still low,considering the absence of targeting propulsion capability.Here,encouraged by the fast-developing controllable microrobotics for targeting delivery,a sunflower-like nanocatalytic active swarm(SNCAS)controlled by a three-dimensional(3D)magnetic field was proposed for synergistic tumorselective and magnetic-actively tumor-targeting therapeutics.Furthermore,a patient-derived renal cancer cell 3D organoid was utilized for the verification of the effective tumor therapeutic outcomes.Under the targeted control of 3D magnetic field,the multiple cascade catalytic efficiency of SNCAS based on Fenton reaction was evaluated,resulting in efficient tumor cell apoptosis and death.For the patient-derived organoid treatment,the SNCAS presented significant lethality toward 3D organoid structure to induce cell apoptosis with the collapse of organoid morphology.The targeting efficiency was further enhanced under the magnetic-controllable of SNCAS.Overall,empowered by the magnetic control technology,the synergistic therapeutic strategy based on controllable swarm combined active targeting and tumor-specific catalytic nanomedicine has provided a novel way for advanced cancer therapy.Meanwhile,3D patient-derived organoids were proved as a powerful tool for the effectiveness verification of nanocatalytic medicine.Dong Liu Ruirui Guo Shuangshuang Mao Yanjie Huang Bin Wang Zijian Wu Xuanjie Xia Jian Dong Yu Xin Ruiyang Xie Jianzhong Shou Wei Sun Yuan Pang Yuan Lu 2023Nano Research2023,16,1:0
8Simulated Reflectance of Apple Trees in Canopy Level Based on the PROSAIL Model and HJ-1A-HSI Data显示文摘Using the PROSAIL radiation transfer model and HJ-1A-HSI data to simulate the canopy reflectivity of apple trees, this study lays the foundation for the inversion of canopy parameters. Taking Qixia City of Yantai City, Shandong Province as the research area, the apple tree was taken as the research object, and the hyperspectral reflectance, LAI and sample GPS of apple canopy were measured in the field. The parameters required for the PROSAIL model were obtained by experimental methods. The model simulates the reflectivity;the HSI image data is preprocessed, and the canopy reflectivity is extracted by GPS coordinates. The PROSAIL model and the HSI image simulated reflectance were fitted to the measured apple canopy reflectivity. The decisive factor (R2) of the simulated reflectance and the measured reflectance of the PROSAIL model was 0.9944, and the relative error (RE%)was 0.1845. The HSI data simulated reflectance and measured reflectance. The coefficient of determination is 0.9714 and the relative error is 0.6202. Both have achieved good fitting effects and can be used for inversion studies of apple canopy parameters.Xiaoyan Guo Xicun Zhu Jingling Xiong Ruiyang Yu Xueyuan Bai Yuanmao Jiang Dongsheng Gao Guijun Yang 2019遥感科学(中英文版)2019,7,1:0
9Inversion of Canopy Nitrogen Content in Apple Orchard Based on GF-1 Satellite Image显示文摘The apple orchard in Qixia City, Yantai City, Shandong Province was used as the research area. The nitrogen content inversion of apple canopy was studied by using the satellite remote sensing images of GF-1. On the basis of GF-1 satellite multispectral image preprocessing, vegetation index was extracted by band math. The nitrogen sensitive vegetation index of apple canopy was selected by correlation analysis of nitrogen content in apple canopy. The best inversion model for the nitrogen content of apple canopy was selected by establishing the regression model of univariate and multivariate factors. The nitrogen content of the canopy of apple orchard in the study area was inverted in space. The results showed that the 6 vegetation indices of RVI, NDVI, EVI, VARI, NPCI and NRI were better correlated with nitrogen content in the vegetation index based on GF-1 satellite multispectral imaging. The best inversion model of nitrogen content in apple canopy layer is the multivariate stepwise regression (MSR) model: Nc = 35.74– 41.978^*NPCI-10.78^*NDVI. The R^2 and RMSE of the model was 0.69 and 1.07. The spatial inversion of nitrogen content in apple orchard canopy was obtained. This study provided theoretical basis and technical support for large-area rapid monitoring of regional fruit tree nutrients.Shujing Cao Xicun Zhu Jingling Xiong Ruiyang Yu Xueyuan Bai uanmao Jiang Dongsheng Gao Guijun Yang 2019遥感科学(中英文版)2019,7,1:0
10Experimental and modeling study of surface topography generation considering tool-workpiece vibration in high-precision turning显示文摘High-precision turning(HPT)is a main processing method for manufacturing rotary high-precision components,especially for metallic parts.However,the generated vibration between tool tip and workpiece during turning may seriously deteriorate the surface integrity.Therefore,exploring the effect of vibration on turning surface morphology and quality of copper parts using 3D surface topography regeneration model is crucial for predicting HPT performance.This developed model can update the machined surface topology in real time.In this study,the effects of tool arc radius,feed rate,radial vibration,axial vibration and tangential vibration on the surface topography and surface roughness were explored.The results show that the effect of radial vibration on surface topography is greater than that of axial vibration and tangential vibration.The radial vibration frequency is also critical.When vibration frequency changes,the surface topography profile presents three different types:the standard sinusoidal curve,the sinusoidal curve whose lowfrequency signal envelopes high-frequency signal,and the oscillation curve whose low-frequency signal superimposes high-frequency signal.In addition,HPT experiment was carried out to validate the developed model.The surface roughness obtained in the experiment was Ra=53 nm,while the roughness obtained by the simulation was Ra=46 nm,achieving a prediction accuracy of 86.7%.Received 4 September 2022;revised 3 October 2022;accepted 17 October 2022.Xingying ZHOU Henan LIU Tianyu YU Ruiyang GUO Guangzhou WANG Yazhou SUN Mingjun CHEN 2023Chinese Journal of Aeronautics2023,36,7:0
11Nuciferine alleviates collagen-induced arthritic in rats by inhibiting the proliferation and invasion of human arthritis-derived fibroblast-like synoviocytes and rectifying Th17/Treg imbalance显示文摘Rheumatoid arthritis(RA)is a chronic autoimmune disorder marked by persistent synovial inflammation and joint degradation,posing challenges in the development of effective treatments.Nuciferine,an alkaloid found in lotus leaf,has shown promising anti-inflammatory and anti-tumor effects,yet its efficacy in RA treatment remains unexplored.This study investigated the antiproliferative effects of nuciferine on the MH7A cell line,a human RA-derived fibroblast-like synoviocyte,revealing its ability to inhibit cell proliferation,promote apoptosis,induce apoptosis,and cause G1/S phase arrest.Additionally,nuciferine significantly reduced the migration and invasion capabilities of MH7A cells.The therapeutic potential of nuciferine was further evaluated in a collagen-induced arthritis(CIA)rat model,where it markedly alleviated joint swelling,synovial hyperplasia,cartilage injury,and inflammatory infiltration.Nuciferine also improved collagen-induced bone erosion,decreased pro-inflammatory cytokines and serum immunoglobulins(IgG,IgG1,IgG2a),and restored the balance between T helper(Th)17 and regulatory T cells in the spleen of CIA rats.These results indicate that nuciferine may offer therapeutic advantages for RA by decreasing the proliferation and invasiveness of FLS cells and correcting the Th17/Treg cell imbalance in CIA rats.WANG Hao GENG Xiaolong AI Fangbin YU Zhilun ZHANG Yan ZHANG Beibei LV Cheng GAO Ruiyang YUE Bei DOU Wei 2024Chinese Journal of Natural Medicines2024,22,4:0
12Multi-locus identification of Psilocybe cubensis by high-resolution melting(HRM)显示文摘Hallucinogenic mushroom is a kind of toxic strain containing psychoactive tryptamine substances such as psilocybin,psilocin and ibotenic acid,etc.The mushrooms containing hallucinogenic components are various,widely distributed and lack of standard to define,which made a great challenge to identification.Traditional identification methods,such as morphology and toxicology analysis,showed shortcomings in old or processed samples,while the DNA-based identification of hallucinogenic mushrooms would allow to identify these samples due to the stability of DNA.In this paper,four primer sets are designed to target Psilocybe cubensis DNA for increasing resolution of present identification method,and the target markers include largest subunit of RNA polymerase II(marked as PC-R1),psilocybin-related phosphotransferase gene(marked as PC-PT),glyceraldehyde 3-phosphate dehydrogenase(marked as PC-3)and translation EF1α(marked as PC-EF).Real-time PCR with high-resolution melting(HRM)assay were used for the differentiation of the fragments amplified by these primer sets,which were tested for specificity,reproducibility,sensitivity,mixture analysis and multiplex PCR.It was shown that the melting temperatures of PC-R1,PC-PT,PC-3 and PC-EF of P.cubensis were(87.93±0.12)℃,(82.21±0.14)℃,(79.72±0.12)℃ and(80.11±0.19)℃ in our kinds of independent experiments.Significant HRM characteristic can be shown with a low concentration of 62.5pg/µL DNA sample,and P.cubensis could be detected in mixtures with Homo sapiens or Cannabis sativa.In summary,the method of HRM analysis can quickly and specifically distinguish P.cubensis from other species,which could be utilized for forensic science,medical diagnosis and drug trafficking cases.Xiaochun Zhang Huan Yu Ziwei Wang Qi Yang Ruocheng Xia Yiling Qu Ruiyang Tao Yan Shi Ping Xiang Suhua Zhang Chengtao Li 2022Forensic Sciences Research2022,7,3:0
13Robustness of interdependent networks with weak dependency links and reinforced nodes显示文摘Interdependent networks are more vulnerable than single,non-interacting networks under cascading failure[1–3].Percolation theory provides a quantifiable theoretical framework to quantify and evaluate the robustness of networked systems.Most existing models[1–3]on the robustness of interdependent networks mainly focused on the giant connected component(GCC)to explore the structural robustness from the macro perspective.Qian LI Hongtao YU Weitao HAN Ruiyang HUANG Shaomei LI Jianpeng ZHANG 2024Science China(Information Sciences)2024,67,2:0
14Chitosan-based carbon dots with multi-color-emissive tunable fluorescence and visible light catalytic enhancement properties显示文摘Carbon quantum dots(CQDs)are receiving increasing attention for their excellent photostability,low toxicity,and tunable fluorescence performance,but it is still challenging to prepare full-spectrum CQDs using only one single set of precursor and solvent.In this study,P and N co-doped carbon dots(N,PR-CQDs)with multi-color-emissive tunable fluorescence from blue to green and orange were synthesized from bio-based chitosan,employing phosphoric acid as solvent and dopant.The introduction of phosphoric acid successfully shortens the manufacturing reaction time,and the heteratomic functional groups of P–O/P=O on surface of carbon dots enrich the surface defect states,promoting n–π*transition,and therefore changing their electron structure/energy level to reduce the band gap,thus facilitating emission at long wavelength.Specifically,increasing phosphoric acid concentration leads to characteristic excitation peaks red shift from 320 to 420 nm with the characteristic emission peaks red shift from 406 to 503 nm.A new emission peak at 610 nm appears,enabling N,PR-CQDs exhibit double emission peaks with fluorescence color from green to yellow to orange.After compositing with carbon nitride(g-C3N4),N,PR-CQDs work as photosensitizer and effectively narrow the energy gap(Eg)of g-C3N4 from 2.75 to 2.40 eV,endowing the photocatalyst higher visible light capture ability and broader light response region.The photocatalytic degradation rate of rhodamine B(RhB)under visible light irradiation reaches up to 98.39%within 60 min using N,P20%-CQDs/g-C3N4 as catalyst,which is 1.4 times that of pure g-C3N4,and it is demonstrated that·O2−is the major active substance contributing for RhB degradation by de-ethyl and aromatic ring breakage.Qiong Wu Shouyun Zhang Shuang Li Yan Yan Shitao Yu Ruiyang Zhao Lang Huang 2023Nano Research2023,16,2:0
15Significance of the auditory meatus inferior wall cartilage in the surgical treatment of congenital first branchial cleft anomalies in children显示文摘Objective To investigate the clinical significance of the inferior wall cartilage of the auditory meatus in surgical treatment of congenital first branchial cleft anomalies(CFBCAs)in children.Methods Twenty children diagnosed with CFBCAs who underwent surgery between December 2018 and June 2022 at our hospital were retrospectively analyzed and classified according to their Work lesion type.The guiding significance of the inferior wall cartilage in the surgical treatment of CFBCAs was summarized by investigating the adjacent relationships of the surgical lesions with the external auditory canal and facial nerve.Results Of the 20 patients,16 were classified as Work type Ⅰ and 4 as Work type Ⅱ.The lesions were adjacent to the inferior wall cartilage of the auditory meatus in all children.Work type Ⅰ lesions were located in the upper lateral aspect and were not adjacent to the facial nerve.Work type Ⅱ lesions were located in the inferior-medial region of the facial nerve.The lesions were completely resected in all children.One patient experienced recurrence 3 months postoperatively because of a residual endochondral fistula.No patients developed facial paralysis or other complications.Conclusions The inferior wall cartilage of the auditory meatus may help to the identify the initial lesion of the CFBCAs and can be regarded as a guiding anatomical structure.These lesions can be completely resected.For resection of Work type II first branchial cleft lesions,the surgical incision can be narrower,and can be precisely positioned with the assistance of endoscope.Bo Yu Ruiyang Zhu Yong Fu Bin Xu Lulu Yu Jing Bi 2023World Journal of Pediatric Surgery2023,6,4:0
16Validation studies of the Para DNA^(■) Intelligence System with artificial evidence items显示文摘Short tandem repeat(STR)profiling is one of the mostly used systems for forensic applications.In certain circumstances,STR profiling is time-consuming and costly,which potentially leads to delays in criminal investigations.LGC(Laboratory of the Government Chemist,UK)Forensics has developed a robust STR profiling platform called the ParaDNAVR Intelligence Test System which can provide early tactical intelligence and aid investigators in making informed decisions on sample prioritization for detection.Here,we validated the ParaDNA^(■) intelligence test for its application in forensic cases using a range of mock evidence items following guidelines set by the Scientific Working Group on DNA Analysis Methods(SWGDAM).Specifically,we tested the sensitivity and accuracy of the ParaDNA intelligence test,as well as the success rates for detecting mock samples and for use in case scenarios.Our findings demonstrate that the ParaDNA intelligence test generates useful DNA profiles,especially for samples such as blood,saliva,and semen that contain ample DNA,indicating the benefits of including ParaDNA as a prior step in forensic STR profiling pipelines.Min Li Ruiyang Tao Wei Zhou Yanan Li Meng Meng Yilun Zhang Linsheng Yu Liqin Chen Yingnan Bian Chengtao Li 2021Forensic Sciences Research2021,6,1:0
17Prediction Model of Nitrogen Content in Apple Leaves based on Ground Imaging Spectroscopy显示文摘A prediction model of apple leaf nitrogen content based on ground imaging spectroscopy was established to rapidly and nondestructively detect nitrogen content in apple leaves.SOC710VP hyperspectral imager was used to obtain the imaging spectral information of apple leaves,and the average spectral curve of interest region was extracted.The study is to analyze the characteristics of imaging spectral curves of apple leaves with different nitrogen content.On the basis of the SG smoothing and first derivative pretreatment of the spectral curve,the maximum sensitive band with nitrogen content is screened and the spectral parameters are constructed.Three modeling methods of BP,SVM and RF were used to establish the prediction model of nitrogen content in apple leaves.The results showed that in the visible range,the nitrogen content of apple leaves was negatively correlated with the reflectance of the spectral curve,and was most obvious in the green range.The R2 of BP,SVM and RF of apple leaf nitrogen content prediction model were 0.7283,0.8128,0.9086,RMSE were 0.9359,0.7365,0.5368,the R2 of test model were 0.6260,0.7294,0.6512,RMSE were 0.9460,0.7350,0.9024.Comparing the prediction results of the three models,the optimal prediction model is SVM model,which can well predict the nitrogen content of apple leaves.Baichao LI Xicun ZHU Ruiyang YU Xiaoyan GUO Shujing CAO Huansan ZHAO 2018遥感科学(中英文版)2018,6,1:0
