| 1 | The Electrochemical Behavior of Au/Au NPs/PNA/ZnS e-QD/ACA Electrode Towards Cy SH Oxidation显示文摘This work describes the electrochemical behavior of azodicarboxamide(ACA) film immobilized on the surface of penicillamine(PNA)/Zn Se-quantum dot(Zn Se-QD) gold nanoparticle(Au NPs) Au electrode. Electrocatalytic activity of modified electrode toward the oxidation of cysteine(Cy SH) was investigated. The surface structure and composition of the sensor were characterized by scanning electron microscopy(SEM). Oxidation of Cy SH on the surface of modified electrode was investigated with cyclic voltammetry, electrochemical impedance spectroscopy(EIS),hydrodynamic voltammetry and chronoamperometry methods. The results show that the PNA/Zn Se-QD/ACA film displays excellent electrochemical catalytic activities towards Cy SH oxidation. The modified electrode shows reproducible behavior and high level of stability during the electrochemical experiments. Also it has short response time, low detection limit, high sensitivity and low operation potential, which can be used as an amperometric sensor for monitoring of Cy SH. The proposed modified electrode was successfully used for determination of Cy SH in real sample such as human serum. | Azadeh Azadbakht Amir Reza Abbasi Zohreh Derikvand Ziba Karimi | 2015 | Nano-Micro Letters2015，7，2： | 3 |
| 2 | Fabrication of a Highly Sensitive Hydrazine Electrochemical Sensor Based on Bimetallic Au-Pt Hybrid Nanocomposite onto Modified Electrode显示文摘In this research a novel nickel complex was used as electrocatalyst for electrooxidation of hydrazine.A nano-structured nickel-complex was electrodeposited on a bimetallic Au-Pt inorganic-organic hybrid nanocomposite modified electrode.The electrode possesses a three-dimensional(3D) porous network nanoarchitecture,in which the bimetallic Au-Pt NPs serving as metal nanoparticle based microelectrode ensembles are distributed in the matrix of interlaced 3,3′,5,5′-Tetramethylbenzidine(TMB) organic nanofibers(NFs).Surface structure and composition of the sensor was characterized by scanning electron microscopy.Electrocatalytic oxidation of hydrazine on the surface of modified electrode was investigated with cyclic voltammetry method.The results showed that the nickelcomplex films displayed excellent electrochemical catalytic activities towards hydrazine oxidation.The hydrodynamic amperometry at rotating modified electrode at constant potential versus reference electrode was used for detection of hydrazine.Under optimized conditions the calibration plots were linear in the concentration range of 0.2-85 μM and detection limit was found to be 0.1 μM.The modified electrode exhibited reproducible behavior and a high level stability during the electrochemical experiments,making it particularly suitable for the analytical purposes. | Azadeh Azadbakht Amir Reza Abbasi | 2010 | Nano-Micro Letters2010，2，4： | 3 |
| 3 | Biochemical and cellular evidence of the benefit of a combination of cerium oxide nanoparticles and selenium to diabetic rats显示文摘AIM: To study the combinative effects of nanocerium and selenium in a murine model of diabetes. METHODS: Cerium oxide (CeO2) nanoparticles (60 mg/kg per day) and sodium selenite (5 μmol/kg per day) aloneor in combination, or the metal form of CeO2 (60 mg/kg) were administered for 2 wk by intraperitoneal injection to streptozotocin-induced diabetic rats. At the end of treatment blood was collected, liver tissue dissected and then oxidative stress markers, extent of energy depletion and lipid prof ile were evaluated.RESULTS: Antioxidant enzymes and high density lipoprotein decreased whereas oxidative stress, adenosine diphosphate/adenosine triphospahte levels, cholesterol, triglyceride and low density lipoprotein increased on induction of diabetes. All were improved by a combination of nanocerium and sodium selenite. There was a relative amelioration by CeO2 nanoparticles or sodium selenite alone, but the metal form of CeO2 showed no signif icant improvement. CONCLUSION: The combination of nanocerium and sodium selenite is more effective than either alone in improving diabetes-induced oxidative stress. | Nazila Pourkhalili Asieh Hosseini Amir Nili-Ahmadabadi Shokoufeh Hassani Mohsen Pakzad Maryam Baeeri Azadeh Mohammadirad Mohammad Abdollahi | 2011 | World Journal of Diabetes2011，2，11： | 2 |

| 5 | Surface-Renewable AgNPs/CNT/rGO Nanocomposites as Bifunctional Impedimetric Sensors显示文摘In this study, glassy carbon electrode modified by silver nanoparticles/carbon nanotube/reduced graphene oxide(AgNPs/CNT/rGO) composite has been utilized as a platform to immobilize cis-dioxomolybdenum(VI)–salicylaldehydehistidine(MoO_2/Sal-His). The modified electrode shows two reversible redox couples for MoO_2/Sal-His. Electrocatalytic oxidation of cysteine(CySH) and electrocatalytic reduction of iodate on the surface of the modified electrode were investigated with cyclic voltammetry and electrochemical impedance spectroscopy methods. The presence of MoO_2/SalHis on AgNPs/CNT/rGO shifted the catalytic current of iodate reduction to a more positive potential and the catalytic current of cysteine oxidation to a more negative potential. The change of interfacial charge transfer resistance(R_(ct))recorded by the modified electrode was monitored for sensitive quantitative detection of CySH and iodate. Moreover, the sensor has a good stability, and it can be renewed easily and repeatedly through a mechanical or electrochemical process. | Azadeh Azadbakht Amir Reza Abbasi Zohreh Derikvand Ziba Karimi Mahmoud Roushani | 2017 | Nano-Micro Letters2017，9，1： | 0 |
| 6 | Highly insulating thermoplastic blends comprising a styrenic copolymer for direct‐current power cable insulation显示文摘The impact of the composition of blends comprising low‐density polyethylene(LDPE),isotactic polypropylene(PP)and a styrenic copolymer additive on the thermomechanical properties as well as the direct‐current(DC)electrical and thermal conductivity is investigated.The presence of 5 weight percent(wt%)of the styrenic copolymer strongly reduces the amount of PP that is needed to enhance the storage modulus above the melting temperature of LDPE from 40 to 24 wt%.At the same time,the copolymer improves the consistency of the thermomechanical properties of the resulting ternary blends.While both the DC electrical and thermal conductivity strongly decrease with PP content,the addition of the styrenic copolymer appears to have little influence on either property.Evidently,PP in combination with small amounts of a styrenic copolymer not only allows to reinforce LDPE at elevated temperatures but also functions as an electrical conductivity‐reducing additive,which makes such thermoplastic ternary formulations possible candidates for the insulation of high‐voltage power cables. | Yingwei Ouyang Amir Masoud Pourrahimi IdaÖstergren Marcus Mellqvist JakobÅnevall Azadeh Soroudi Anja Lund Xiangdong Xu Thomas Gkourmpis Per‐Ola Hagstrand Christian Müller | 2022 | High Voltage2022，7，2： | 0 |
