1Electrochemical performance of a three-layer electrode based on Bi nanoparticles,multi-walled carbon nanotube composites for simultaneous Hg(Ⅱ)and Cu(Ⅱ)detection显示文摘Electrochemical analysis is a promising technique for detecting biotoxic and non-biodegradable heavy metals.This article proposes a novel composite electrode based on a polyaniline(PANi)fra mework doped with bismuth nanoparticle@graphene oxide multi-walled carbon nano tubes(Bi NPs@GO-MWCNTs)for the simultaneous detection of multiple heavy metal ions.Composite electrodes are prepared on screenprinted electrodes(SPCEs)using an efficient dispensing technique.We used a SM200 SX-3 A dispenser to load a laborato ry-specific ink with optimized viscosity and adhesion to draw a pattern on the work area.The SPCE was used as substrate to facilitate cost-effective and more convenient real-time detection technology.Electrochemical techniques,such as cyclic voltammetry and differential pulse voltammetry,were used to demonstrate the sensing capabilities of the proposed sensor,The sensitivity,limit of detection,and linear range of the PANi-Bi NPs@GO-MWCNT electrode are 2.57×10^(2)μA Lμmol^(-1) cm^-2,0.01 nmol/L,and 0.01 nmol/L-5 mmol/L and 0.15×10^(-1)μALμmol^(-1) cm^-2,0.5 nmol/L,and 0.5 nmol/L-5 mmol/L for mercury ion(Hg(Ⅱ))and copper ion(Cu(Ⅱ))detection,respectively.In addition,the electrode exhibits a good selectivity and repeatability for Hg(Ⅱ)and Cu(Ⅱ)sensing when tested in a complex heavy metal ion solution.The constructed electrode system exhibits a detection performance superior to similar methods and also increases the types of heavy metal ions that can be detected.Therefore,the proposed device can be used as an efficient sensor for the detection of multiple heavy metal ions in complex environments.Qiwen Bao Gang Li Zhengchun Yang Peng Pan Jun Liu Jiayuan Chang Jun Wei Ling Lin 2020Chinese Chemical Letters2020,31,10:2
2Physiological Response of Oncidium hybridum‘Gower Ramsey’Infected by Erwinia carotovora显示文摘[Objective]The paper was to study the physiological mechanism of Oncidium hybridum‘Gower Ramsey’infected by Erwinia carotovora pv.carotovora.[Method]O.hybridum‘Gower Ramsey’was inoculated with E.carotovora by needle-punching method.The leaves inoculated with sterile water were used as control,and samples were collected at 12,24,36 and 48 h post inoculations to determine the physiological indexes,respectively.[Result]The contents of MDA,flavonoid,lignin,soluble protein and the activities of POD,SOD,CAT,PPO and PAL in O.hybridum leaves first increased then decreased.At 12 h post inoculation,the activities of SOD and CAT increased significantly by 40.49%and 37.77%(P<0.01,the same below),respectively;the contents of flavonoid increased significantly by 21.56%(P<0.05,the same below);and the activities of PAL,POD and PPO increased significantly by 42.29%,81.8%and 37.98%,respectively.The contents of MDA and lignin increased significantly by 57.98%and 58.72%at 24 h,respectively;the content of soluble protein increased by 87.71%at 24 h,and 61.28%at 36 h,while the content of Pro increased at 24 h(P>0.05,the same below),and increased significantly by 23.66%at 36 h;the content of soluble sugar content had no significant difference compared with the control.Additionally,the chlorophyll a and carotenoid contents tended to decrease dramatically,while chlorophyll b increased significantly by 95.33%at 24 h,then decreased.The initial fluorescence parameter of Fm/Fv and Y(II)decreased significantly by 47.14%and 54.61%,respectively,while the Y(NO)increased significantly by 33.61%,compared with the control.[Conclusion]The contents of Pro,MDA,lignin,soluble protein and the activities of POD,SOD,CAT,PPO and PAL in O.hybridum leaves are closely related to the infection of E.carotovora,which provide new clues for revealing the infection mechanism of E.carotovora in O.hybridum.Lin Zhengchun Ni Shanshan Wu Qiuzhen Lai Zhongxiong 2020Plant Diseases and Pests2020,11,5:2

12Effects of Different Line Spacing and Seedling Belt Width on Yield Formation of Broad-Width Fine Sowing Wheat显示文摘In order to explore the interaction effects of line spacing and seedling belt width on wheat yield formation and improve the cultivation techniques of broadwidth and fine seeding of wheat,a high-yielding winter wheat cultivar Shannong 28 was selected as material. Using the split plot design,the main plot was set with line spacing as 20,25 and 30 cm,respectively,and the sub-plot was set with seedling belt width as 3,5,7,9 and 11 cm,respectively. Then,the population dynamics,dry matter accumulation and translocation and yield of wheat were studied under the experimental conditions. The results showed that under the line spacing of 20 cm,the dry matter accumulation and yield of winter wheat were higher with the seedling belt width of 5 cm. When the line spacing was 25 cm,the dry matter accumulation and yield under the seedling belt width of 9 cm reached a high level. Under the line spacing of 30 cm,Shannong 28 achieved higher dry matter accumulation and yield with the seedling belt width of 11 cm. Comprehensive analysis revealed that the suitable treatment for Shannong 28 was 25 cm of line spacing with 9 cm of seedling belt width,which could realize the coordination of the three factors of yield composition and get higher yield. Therefore,the reasonable line spacing and seedling belt width were the important technical ways to realize high yield of wheat.Minmin SHAO Leiming SUN Kai ZHAO Xingke XU Ling HUANG Lin WANG Lu YAN Zhengchun JU 2020Agricultural Biotechnology2020,9,3:0
13A ternary heterogeneous hydrogel with strength elements for resilient,self-healing,and recyclable epidermal electronics显示文摘Epidermal sensing devices,which mimic functionalities and mechanical properties of natural skin,offer great potential for real-time health monitoring via continuous checking of vital signs.However,most existing skin-mounted electronics use a flexible film with high elastic modulus,which hinders physical activity and causes interfacial delamination and skin irritation.The compliance of hydrogel-based devices can firmly conform to complex,curved surfaces without introducing excessive interfacial stresses.However,most hydrogels still suffer from the weakness of stable and reproducible sensing.In this work,we report a skin-friendly epidermal electronic made of a resilient,self-healing,and recyclable polyvinyl alcohol(PVA)hydrogel.The hydrogel is reinforced through a ternary heterogeneous network for good mechanical robustness while maintaining high stretchability and exceptional conformability.Simultaneously,the abundant dynamic hydrogen bonds give the hydrogel rapid self-healing ability.The assembled hydrogel epidermal electronic is able to stably monitor multiple physiological signals as well as sense the strain level of the skin motion and joint bending.The unique,versatile,environmental and biological friendly epidermal electronics will have broad applications in health care,human-machine interface,augmented reality,and so on.Ziya Wang Xiuru Xu Yingtian Xu Waner Lin Zhengchun Peng 2022npj Flexible Electronics2022,6,1:0
14One-Dimensional(NH=CINH_(3))_(3)PbI_(5)Perovskite for Ultralow Power Consumption Resistive Memory显示文摘Organic-inorganic hybrid perovskites(OIHPs)have proven to be promising active layers for nonvolatile memories because of their rich abundance in earth,mobile ions,and adjustable dimensions.However,there is a lack of investigation on controllable fabrication and storage properties of one-dimensional(1D)OIHPs.Here,the growth of 1D(NH=CINH_(3))_(3)PbI_(5)((IFA)_(3)PbI_(5))perovskite and related resistive memory properties are reported.The solution-processed 1D(IFA)_(3)PbI_(5)crystals are of welldefined monoclinic crystal phase and needle-like shape with the length of about 6 mm.They exhibit a wide bandgap of 3 eV and a high decomposition temperature of 206℃.Moreover,the(IFA)_(3)PbI_(5)films with good uniformity and crystallization were obtained using a dual solvent of N,N-dimethylformamide(DMF)and dimethyl sulfoxide(DMSO).To study the intrinsic electric properties of this anisotropic material,we constructed the simplest memory cell composed of only Au/(IFA)_(3)PbI_(5)/ITO,contributing to a high-compacted device with a crossbar array device configuration.The resistive random access memory(ReRAM)devices exhibit bipolar current-voltage(I-V)hysteresis characteristics,showing a record-low power consumption of~0.2 mW among all OIHP-based memristors.Moreover,our devices own the lowest power consumption and“set”voltage(0.2 V)among the simplest perovskite-based memory devices(inorganic ones are also included),which are no need to require double metal electrodes or any additional insulating layer.They also demonstrate repeatable resistance switching behaviour and excellent retention time.We envision that 1D OIHPs can enrich the low-dimensional hybrid perovskite library and bring new functions to low-power information devices in the fields of memory and other electronics applications.Xuefen Song Hao Yin Qing Chang Yuchi Qian Chongguang Lyu Huihua Min Xinrong Zong Chao Liu Yinyu Fang Zhengchun Cheng Tianshi Qin Wei Huang Lin Wang 2021Research2021,,1:0
