The development of even more compact, inexpensive, and highly sensitive gas sensors is widespread, even though their performances are still limited and technological improvements are in continuous evolution. Zeolite is a class of material which has received particular attention in different applications due to its interesting adsorption/desorption capabilities. The behavior of a zeolite 4A modified capacitor has been investigated for the adsorption of nitrogen (N2), nitric oxide (NO) and 1,1-Difluoroethane (C2H4F2), which are of interest in the field of chemical, biological, radiological, and nuclear threats. Sample measurements were carried out in different environmental conditions, and the variation of the sensor electric capacitance was investigated. The dielectric properties were influenced by the type and concentration of gas species in the environment. Higher changes in capacitance were shown during the adsorption of dry air (+4.2%) and fluorinated gas (+7.3%), while lower dielectric variations were found upon exposure to N2 (−0.4%) and NO (−0.5%). The proposed approach pointed-out that a simple fabrication process may provide a convenient and affordable fabrication of reusable capacitive gas sensor.
Convergence between business environment and technology solutions is a today challenge: is it possible to identify and adapt traditional business analysis tools into IT infrastructure and viceversa ? Mobile business has already dramatically changed our way of life: to get the most of it, it is necessary to understand how and when to take the next step in order to achieve the best possible results. After a short description of the current and available Mobile technologies, the chapter tackles the solutions that some companies have already implemented, enabling thus customers and stakeholder to efficiently and effectively cooperate: yes, because the bog news in mobile business is that such a technology makes business process and communications (either internal and external) visible. It is a true “one stop shop” where people are really always connected. It is now possible to create a framework where business environment and mobile solutions get together, enabling the development of a roadmap (or a mindset if you prefer so) that can be used to create new services.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
