Sensors, Vol. 14, Pages 24029-24045: A Self-Referenced Optical Intensity Sensor Network Using POFBGs for Biomedical Applications

12-Dec-2014 | Moraleda, Alberto Tapetado; Montero, David Sánchez; Webb, David J.; García, Carmen Vázquez, Sensors, 2014

This work bridges the gap between the remote interrogation of multiple optical sensors and the advantages of using inherently biocompatible low-cost polymer optical fiber (POF)-based photonic sensing. A novel hybrid sensor network combining both silica fiber Bragg gratings (FBG) and polymer FBGs ...

Sensors, Vol. 14, Pages 23970-24003: A Multi-Sensor RSS Spatial Sensing-Based Robust Stochastic Optimization Algorithm for Enhanced Wireless Tethering

12-Dec-2014 | Parasuraman, Ramviyas ; Fabry, Thomas ; Molinari, Luca ; Kershaw, Keith ; Castro, Mario Di; Masi, Alessandro ; Ferre ..., Sensors, 2014

The reliability of wireless communication in a network of mobile wireless robot nodes depends on the received radio signal strength (RSS). When the robot nodes are deployed in hostile environments with ionizing radiations (such as in some scientific facilities), there is a possibility that some ...

Determination of Total Protein Concentration in Solution Using Gold Electrode Modified with Silver Nanoparticles

11-Dec-2014 | Patrick Marcel Seumo Tchekwagep , Charles Péguy Nanseu‐Njiki, Emmanuel Ngameni, Ravi Danielsson, Thomas Arnebrant, T ..., Electroanalysis, 2014

Abstract Gold electrodes were modified with silver nanoparticles and Ag/AgCl redox conversion was recorded by cyclic voltammetry in protein containing electrolyte solution. The charge of the reduction peak decreased with the increase of the total protein concentration. This correlation was ...

Characterization of the startup transient electrokinetic flow in rectangular channels of arbitrary dimensions, zeta potential distribution, and time‐varying pressure gradient

11-Dec-2014 | Andrew Miller, Arturo Villegas, F. Javier Diez, ELECTROPHORESIS, 2014

The solution to the startup transient electroosmotic flow in an arbitrary rectangular micro‐channel is derived analytically and validated experimentally. This full two dimensional transient solution describes the evolution of the flow through five distinct periods until reaching a final steady ...

Separation and purification of both tea seed polysaccharide and saponin from camellia cake extract using macroporous resin

10-Dec-2014 | Pengjie Yang, Mingda Zhou, Chengyun Zhou, Qian Wang, Fangfang Zhang, Jian Chen, Journal of Separation Science, 2014

A novel method to separate and purify tea seed polysaccharide and tea seed saponin from camellia cake extract by macroporous resin was developed. Among four kinds of resins (AB‐8, NKA‐9, XDA‐6, and D4020) tested, AB‐8 macroporous resin possessed optimal separating capacity for the two substances ...

A solvent replenishment solution for managing evaporation of biochemical reactions in air-matrix digital microfluidics devices

10-Dec-2014 | Mais J. Jebrail; Ronald F. Renzi; Anupama Sinha; Jim Van De Vreugde; Carmen Gondhalekar; Cesar Ambriz; Robert J. Mea ..., Lab on a Chip, 2014

Digital microfluidics (DMF) is a powerful technique for sample preparation and analysis for a broad range of biological and chemical applications. In many cases, it is desirable to carry out DMF on an open surface, such that the matrix surrounding the droplets is ambient air. However, the utility ...

Online mercury determination by laser-induced breakdown spectroscopy with assistance of solution cathode glow discharge

10-Dec-2014 | Peichao Zheng; Hongdi Liu; Jinmei Wang; Minjie Shi; Xiaomeng Wang; Bin Zhang; Rui Yang, Journal of Analytical Atomic Spectrometry, 2014

The trace mercury in aqueous solution is determined by laser-induced breakdown spectroscopy (LIBS) under the assistance of solution cathode glow discharge (SCGD) system. The aqueous solution is converted to gas phase using high voltage DC discharge, and then the generated mercury vapor is cooled ...
