Both ammonia and phosphine are widely used in industrial processes, yet they noxious exhibit detrimental effects on human health. Despite the remarkable progress sensors development, there still some limitations, for instance, requirement of high operating temperatures, that most solely dedicated to individual gas monitoring. Herein, an ultrasensitive, highly discriminative platform is demonstr...

The total internal partition function of ammonia (NH3) and phosphine (PH3) are calculated as a function of temperature by explicit summation of 153 million (for PH3) and 7.5 million (for NH3) theoretical rotation-vibrational energy levels. High accuracy estimates are obtained for the specific heat capacity, Cp, the Gibbs enthalpy function, gef, the Helmholtz function, hcf, and the entropy, S, o...

The fabrication of a gas nanosensor for detecting ammonia gas in air that is unaffected by humidity is demonstrated. On functionalizing single-walled carbon nanotube (SWNT) networks with a precise amount of camphorsulfonic-acid-doped polyaniline (PANI(CSA)), the opposite electrical resistance responses of the CSA-doped PANI and SWNTs to humid air effectively canceled each other, thereby elimina...

Introduction: The last comprehensive photochemical model for Jupiter’s troposphere was presented by Edgington et al. [1,2], based upon the work of Atreya et al. [3] and Kaye and Strobel [4-6]. Since these early studies, numerous laboratory experiments have led to an improvement in our understanding of PH3, NH3-PH3, and NH3-C2H2 photochemistry [7-13]. Furthermore, recent Galileo, Cassini, and Ea...

This paper provides an in-depth view on nanosensor technology and electromagnetic communication among nanosensors. First, the state of the art in nanosensor technology is surveyed from the device perspective, by explaining the details of the architecture and components of individual nanosensors, as well as the existing manufacturing and integration techniques for nanosensor devices. Some intere...
