Active 433 MHz-W UHF RF-powered chip integrated with a nanocomposite m-MWCNT/polypyrrole sensor for wireless monitoring of volatile anesthetic agent sevoflurane

Chemical event tracking using a low-cost wireless chemical sensing network

“…Subsequently, the emitter LED in series with a 1 kΩ current limiting resistor is activated to act as a consistent light source over repeated sample measurements. In a simultaneous operation the state of the pin connected to the cathode of the detector LED is reversed, allowing the capacitance to discharge into a microcontroller at a rate dependent on the light intensity reaching the LED [8]. The logic state of the discharging pin is checked for a fixed number of microcontroller processor counts (4000).…”

“…Some published examples include a single RF wireless chemical sensor node which used a magnetoelastic sensor array to measure pH in an aquatic environment [7]. Chavali et al presented results from a single electro-chemical sensor operating on a Mica2Dot mote platform for the detection of a volatile anesthetic agent [8].…”

Integration of Mobile Control Systems Into Intermodal Container Transportation Management

“…Whüe there is much Hterature about the route optimization of intermodal transport (Macharis et al 2010;Ishfaq, Sox 2010;Macharis, Pekin 2009;Limbourg, Jourquin 2009;Janic 2008;Chang 2008;Sirikijpanichkul et al 2007), logistic chain analysis (Shariat-Mohaymany, Babaei 2010) and intermodal transportation manage-ment (Thül, Lim 2010;Kreutzberger 2008;Sirüdjpanichkul et al 2007), comparatively little has been written about applying sensors and RFID technologies in intermodal container transportation (Wen 2010;Amador, Emond 2010;Chavali et al 2008), the security of transferring RFID data (Kaya et al 2009) and employing other information technologies (Oztekin et al 2010;Dias et al 2009). The basis for this paper has been provided by Ngai et al (2007), Woo et al (2009) and Ferrer et al (2010).…”

Thin Nanocomposite Films of Polyaniline/Au Nanoparticles by the Langmuir−Blodgett Technique

“…[1][2][3][4]6,8 The methods of preparing conducting polymer nanocomposites have been reviewed by Gangopadhyay 3 and Jang 2 and researched by several groups. [22][23][24][25][26][27][28][29][30][31][32][33][34] The most straightforward approach to assembling conducting polymer nanocomposites involves chemical 13,17 or electrochemical polymerization in the presence of NPs that results in the formation of thin nanocomposite films (on the order of a few micrometers). For example, Visy and co-workers prepared polythiophene-magnetite composite layers through the electropolymerization of 3-thiopheneacetic acid in the presence of Fe 3 O 4 nanoparticles.…”
