Sensors, Vol. 15, Pages 6699-6718: Soil Water Content Assessment: Critical Issues Concerning the Operational Application of the Triangle Method

19.03.2015 | Maltese, Antonino ; Capodici, Fulvio ; Ciraolo, Giuseppe ; Loggia, Goffredo La, Sensors, 2015

Knowledge of soil water content plays a key role in water management efforts to improve irrigation efficiency. Among the indirect estimation methods of soil water content via Earth Observation data is the triangle method, used to analyze optical and thermal features because these are primarily ...

Tandem differential mobility spectrometry with ion dissociation in air at ambient pressure and temperature

16.03.2015 | Marlen Menlyadiev; Alexander tarassov; Gary A Eiceman; Alexander Kielnecker, Analyst, 2015

Proton bound dimers were dissociated to protonated monomers in air at ambient pressure and temperature using electric fields of an ultrahigh Field Asymmetric Ion Mobility Spectrometry (ultraFAIMS) with the onset of dissociation for ethyl acetate as 96 Td and for dimethyl methyl phosphonate as 170 ...

Influence of thermal annealing on the structural and optical properties of maghemite (γ‐Fe2O3) nanoparticle thin films

13.03.2015 | Ehsan Parsianpour, Mohammad Gholami, Nima Shahbazi, Feridoun Samavat, Surface and Interface Analysis, 2015

In this study, maghemite (γ‐Fe2O3) nanoparticles were initially synthesized via chemical co‐precipitation and then deposited by spray pyrolysis as thin films on white glass substrates. The thin films were annealed for 8 h at 400, 450, 500, 550, and 600 °C in an oven. The structural studies of ...

Sensors, Vol. 15, Pages 5820-5864: Fortified Anonymous Communication Protocol for Location Privacy in WSN: A Modular Approach

10.03.2015 | Abuzneid, Abdel-Shakour ; Sobh, Tarek ; Faezipour, Miad ; Mahmood, Ausif ; James, John, Sensors, 2015

Wireless sensor network (WSN) consists of many hosts called sensors. These sensors can sense a phenomenon (motion, temperature, humidity, average, max, min, etc.) and represent what they sense in a form of data. There are many applications for WSNs including object tracking and monitoring where ...

Synthesis of Novel CuO Nanosheets with Porous Structure and Their Non‐Enzymatic Glucose Sensing Applications

09.03.2015 | Fang Sun, Ruihua Zhu, Hongwei Jiang, Hailiang Huang, Peng Liu, Youjin Zheng, Electroanalysis, 2015

Abstract Novel CuO thin films composed of porous nanosheets were in situ formed on indium tin oxide (ITO) by a simple, low temperature solution method, and used as working electrodes to construct nonenzymatic glucose sensor after calcinations. Cyclic voltammetry revealed that the CuO/ITO ...

A capillary zone electrophoresis method for the direct determination of amino acids in recombinant human erythropoietin preparations used for the treatment of anemia

09.03.2015 | Izabel Cristina de Souza Crespo, Matheus Troina Resende, Annibal Duarte Pereira Netto, Flávia Ferreira de Carvalho M ..., ELECTROPHORESIS, 2015

A method based on capillary zone electrophoresis for the determination of glutamic acid, glycine and alanine in a biopharmaceutical formulation containing recombinant human erythropoietin was developed. The separation was achieved within less than 5min, using a fused‐silica capillary column ...

Transformations of iodine species inside elliptical channels of AlPO4‐11 crystals at low temperature: a Raman study

09.03.2015 | Shuanglong Chen, Mingguang Yao, Ye Yuan, Fengxian Ma, Zhaodong Liu, Bing Li, Ran Liu, Quanjun Li, Bo Zou, Tian Cui, ..., Journal of Raman Spectroscopy, 2015

Raman spectra of iodine species confined in one‐dimensional elliptical channels of AlPO4‐11 (AEL) crystals have been studied from room temperature down to −196 °C. As temperature decreases, thermal fluctuations of individual iodine molecules confined in AEL channels are slowed down and they ...

Sensors, Vol. 15, Pages 5583-5593: Interstitial Photoacoustic Sensor for the Measurement of Tissue Temperature during Interstitial Laser Phototherapy

06.03.2015 | Li, Zhifang ; Chen, Haiyu ; Zhou, Feifan ; Li, Hui ; Chen, Wei R., Sensors, 2015

Photothermal therapy is an effective means to induce tumor cell death, since tumor tissue is more sensitive to temperature increases than normal tissue. Biological responses depend on tissue temperature; target tissue temperature needs to be precisely measured and controlled to achieve desired ...

Sensors, Vol. 15, Pages 5594-5608: Temperature-Phase Converter Based on a LC Cell as a Variable Capacitance

06.03.2015 | Torres, Juan Carlos; García-Cámara, Braulio ; Pérez, Isabel ; Urruchi, Virginia ; Sánchez-Pena, José Manuel, Sensors, 2015

The main characteristic of liquid crystals is that their properties, both electrical and optical, can be modified through a convenient applied signal, for instance a certain voltage. This tunable behavior of liquid crystals is directly related to the orientation of their nanometric components ...
