Electrochemical Determination of Cu(II) Using a Glassy Carbon Electrode Modified with Multiwall Carbon Nanotubes Dispersed in Polyhistidine

23-Jul-2015 | Pablo R. Dalmasso, María L. Pedano, Gustavo A. Rivas, Electroanalysis, 2015

Abstract We report the sensitive and selective quantification of Cu(II) at glassy carbon electrodes (GCE) modified with multiwall carbon nanotubes (MWCNT) dispersed in polyhistidine (Polyhis), (GCE/MWCNTPolyhis) based on the complexation of Cu(II) by the histidine residues and further ...

Sustainability, Vol. 7, Pages 9773-9786: Experimental Investigation on the Effect of Phase Change Materials on Compressed Air Expansion in CAES Plants

23-Jul-2015 | Castellani, Beatrice ; Presciutti, Andrea ; Filipponi, Mirko ; Nicolini, Andrea ; Rossi, Federico, Sustainability, 2015

The integration of renewable energy in the electrical grid is challenging due to the intermittent and non-programmable generated electric power and to the transmission of peak power levels. Several energy storage technologies have been studied to find a solution to these issues. In particular, ...

Sensors, Vol. 15, Pages 17977-17989: Zn(II)-Coordinated Quantum Dot-FRET Nanosensors for the Detection of Protein Kinase Activity

23-Jul-2015 | Lim, Butaek ; Park, Ji-In ; Lee, Kyung Jin; Lee, Jin-Won ; Kim, Tae-Wuk ; Kim, Young-Pil, Sensors, 2015

We report a simple detection of protein kinase activity using Zn(II)-mediated fluorescent resonance energy transfer (FRET) between quantum dots (QDs) and dye-tethered peptides. With neither complex chemical ligands nor surface modification of QDs, Zn(II) was the only metal ion that enabled the ...

Sensors, Vol. 15, Pages 17926-17943: Development of a Plug-and-Play Monitoring System for Cabled Observatories in the East China Sea

23-Jul-2015 | Yu, Yang ; Xu, Huiping ; Xu, Changwei, Sensors, 2015

Seafloor observatories enable long term, continuous and multidisciplinary observations, promising major breakthroughs in marine environment research. The effort to remotely control in situ multidisciplinary equipment performing individual and cooperative tasks is both a challenge and a guarantee ...

IJERPH, Vol. 12, Pages 8678-8690: Evaluation of Combined Disinfection Methods for Reducing Escherichia coli O157:H7 Population on Fresh-Cut Vegetables

23-Jul-2015 | Petri, Eva ; Rodríguez, Mariola ; García, Silvia, International Journal of Environmental Research and Public Health, 2015

Most current disinfection strategies for fresh-cut industry are focused on the use of different chemical agents; however, very little has been reported on the effectiveness of the hurdle technology. The effect of combined decontamination methods based on the use of different sanitizers ...

Ratiometric fluorescent detection of silver ions using thioflavin T-based organic/inorganic hybrid supraparticles

22-Jul-2015 | Yan-Yun Li; Min Zhang; Ling-Fei Lu; Anwei Zhu; Fei Xia; Tianshu Zhou; Guoyue Shi, Analyst, 2015

In this work, we present a new type of functional organic/inorganic hybrid supraparticles that spontaneously assemble from silver ions (Ag+), iodide ions (I-) and thioflavin T (ThT) under an aqueous solution condition. ThT alone in aquous solution was weakly fluorescent with emission band at 494 ...

Sensors, Vol. 15, Pages 17767-17785: Discrimination of Rice with Different Pretreatment Methods by Using a Voltammetric Electronic Tongue

22-Jul-2015 | Wang, Li ; Niu, Qunfeng ; Hui, Yanbo ; Jin, Huali, Sensors, 2015

In this study, an application of a voltammetric electronic tongue for discrimination and prediction of different varieties of rice was investigated. Different pretreatment methods were selected, which were subsequently used for the discrimination of different varieties of rice and prediction of ...

Sensors, Vol. 15, Pages 17808-17826: Real-Time PPP Based on the Coupling Estimation of Clock Bias and Orbit Error with Broadcast Ephemeris

22-Jul-2015 | Pan, Shuguo ; Chen, Weirong ; Jin, Xiaodong ; Shi, Xiaofei ; He, Fan, Sensors, 2015

Satellite orbit error and clock bias are the keys to precise point positioning (PPP). The traditional PPP algorithm requires precise satellite products based on worldwide permanent reference stations. Such an algorithm requires considerable work and hardly achieves real-time performance. However, ...

Solution or Gas Phase? Oxidation and Radical Formation in Electrospray Ionization Mass Spectrometry (ESI MS)

21-Jul-2015 | Imran Iftikhar, Anna Brajter‐Toth, Electroanalysis, 2015

Abstract The relationship between one‐electron (e−) oxidation processes and the formation of radical cations of endogenous and exogenous compounds in vivo is of considerable interest. This paper reports on the experiments that allow detection of ion signals that are consistent with the ...
