Comparative study of chemo-bio synthesized MgO nano particles for LPG sensing

Goutham S., Kumar D.S., Rao K.V., JNT UNiversity Hyderabad, IN

Present work is a comparative study for LPG sensor which is developed by two materials by chemical and green method. LPG sensing dynamic characteristics were examined.

Visible Light Absorbing Photoremovable Protecting Groups

Juetten M., Iowa State University Research Foundation, US

Photoremovable protecting groups (or “photocages” or “phototriggers”) are light-sensitive chemical moieties that provide control over the release of any number of reagents in a variety of environments. While photocages have important applications in areas such [...]

Evaluation of In2O3 prepared by the delayed ignition combustion process as a gas sensor

Lionti K., Fasoli A., Sundberg L., Ceccarelli F., Miller R.D., Bozano L., IBM Research - Almaden, US

Metal oxide semiconductor (MOS) gas sensors based on thin film technology offer the potential of higher sensitivity and faster response and recovery than their thick film counterparts. Solution-based approaches are facile and inexpensive routes to [...]

Cyber-Physical Magnetic Field Sensors

Kravljaca V., Rochester Institute of Technology, US

Solid state magnetic field sensors are examined. The use of III-V semiconductors in Hall effect sensors results in high bandwidth, fast response time, adequate spatiotemporal resolution, accuracy and sufficient measurement range. Despite significant advantages, there [...]

Zinc Oxide optical and chemical sensors fabricated by Ink Jet printing and drop casting

Ewing D.J., Casper M., Stramel A., Morick B., Cook B., Wu J., The Department of Energy's Kansas City National Security Campus, US

Zinc oxide (ZnO) nanostructures show great promise for a variety of applications, such as UV detectors, chemical, and gas sensors. Zinc oxide has a direct bandgap (3.4 eV), a high electron mobility, and environmental stability. [...]

A New Gas/Supercritical Fluid (SCF) Diffusivity and Solubility Measurement Method for CO2 Saturated Polymer Systems Using Optical Transmission Property

Yao S.X., Lee J-K, Lee J., Lee P-C, Lee J-K, Lee J., Lee P-C, Jun M.B.G., Lee J-K, Lee J., Lee P-C, University of Vermont, US

Supercritical fluids (SCFs) and gases are widely used in polymer processing. For example, plastic foam products used for light-weight structural components, heat insulation, and food packaging can be fabricated by nano-/micro-cellular foaming processes with gases [...]

Photonic Crystal Fiber Based Refractive Index Sensor

Nazeri K., Ahsani V., Ahmed F., Lee P-C, Jun M.B.G., Purdue University, US

Photonic Crystal Fiber (PCF) is an optical fiber which owes its waveguide properties to an arbitrary arrangement of closely-spaced and tiny air holes that go through the whole length of fiber. Much attention has been [...]

Self-Sustained Infrared Temperature Sensor Arrays

Mittmann Reis R., Rochester Institute of Technology, US

The constantly growing needs for solid-state temperature sensors motivates micromachined thermopile sensors [1-11]. We examine the Seebeck effect and discuss the the key physical parameters and characteristics. The micromachined microstructures are designed and fabricated. We [...]

Self-Assembled Polystyrene Nanospheres for Plasmonic Enhancement in Biosensor Applications

Smith K., Norville C., Windham M., Dawson J.M., West Virginia University, US

The field of portable, point-of care biosensing has expanded in recent years to encompass a wide range of application areas, with detection of targets accomplished by a variety of techniques. Application-specific needs of further reduced [...]

LIF based fluorescent immunosensor using AP-SNs and QDs for quantitation of IgG anti Toxocara canis in human serum samples

Messina G.A., Aranda P.R., Pereira S.V., Bertolino F.A., Raba J., INQUISAL, National University of San Luis, CONICET, AR

Toxocariasis, one of the most common zoonotic infection worldwide, is caused by Toxocara canis (T. canis), or less commonly, Toxocara cati [1,2]. In humans, the infection is acquired by oral route through accidental ingestion of [...]
