Impedance measurements based on voltage pulse injection and current detection are simple to implement and fast, but transients produced in the current-to-voltage converter can yield large deviations in the impedance measured. Because those transients depend on the impedance being measured itself, it is difficult to avoid them when the measurement range is large. We propose to reduce those transients by controlling the rise time of the pulse being injected. For a particular implementation of the method, transient amplitude has been reduced to less than 2 % of the full scale voltage, as compared to 36 % overshoot for fast voltage pulses.

A new concept of hybrid bio-sensors are proposed for collecting microfluidic probes, in order to study and treat neurological disorders. The micro-electrode features at nanoscale are based on incorporating via electropolymerization of oxidized conjugated polymer - as charge-balancing - with dopants (e.g. Pyrrole derivatives, PEDOT, ProDOT, ProDOP and their copolymers), at the surface of carbon structures with nanopores of predefined architectures. The mechanical, fatigue and adhesion properties of the experimental coatings were assessed by using nanoindentation, high frequency impact and scratch specific tests. The electrochemical characterization (Potentiostat/Galvanostat method) was performed by using reference redox molecules such as ferricyanide, p-aminophenol, hydroquinone etc. Some applications were emphasized by testing the sensors sensitivity and reproducibility at different concentrations of dopamine, epinephrine and norepinephrine in acid medium (0.1 M HCl). In order to tailor the hybrid bio-sensors for medical applications, the potential interferences within biological samples of ascorbic acid, uric acid etc. were also taken into account. Finally, a functional on-chip model was developed, by integrating: interaction area (microelectrode exposure array), detection area (detection circuits) and processing and transmission area (signal processing and communication features).

This paper describes how to publish data coming from scattered and heterogeneous Electromagnetic (EM) field sensing systems in compliance with novel knowledge management techniques. Ontological modeling and Linked Data Principles have been exploited to interlink and organize, from a semantic point of view, measurement data with additional information describing sensors, measurement sites and techniques, emitting sources and devices, etc. From the very first achieved results, the proposed approach exhibits many appealing features. For instance, the possibility to seamlessly access different legacy data sources or to create semantic relationships across related scientific areas. Therefore, traditional data publication techniques for EM pollution monitoring campaigns can now be thought-back and broadened by adding new features to reach more variegated categories of users rather than only technicians or managing authorities.

In the last ten years town of Taranto (Italy) is living a decisive phase of its own history, since is torn between the presence of some big hazardous industrial plants and the strong demand of eco-sustainable development. The increasing of manufacturing industries has leaded an undeniable economic and social growth, but, at the same time, has exposed the whole area to great environmental stresses. This concern is particularly true also for the Port of Taranto (PoT) because the harbor area is very close to the city, contributing to expose people to risk of serious health hazards. Although the PoT activity had not a relevant impact on total pollutant emissions in the area, its location makes mandatory an environmental requalification.
The purpose of this study is to gather and analyze the data associated with the berthing operations and resulting emissions to better define the potential for emissions reductions and to suggest some possible strategies for bringing pollutants down, in order to reach a wealth based on environmental preservation.

Through analytical modeling of fluid flow and geomechanical phenomena is here given birth to an energy system that integrates CCS and geothermal energy. It uses the injection of CO₂ in deep saline aquifers to generate a range of pressures that facilitates the upgrade of geothermal fluids from geological formations that constitute the caprock or any porous aquifers overlaid with the aquifer reservoir. the uptake of these fluids promotes dissipate excess pressure and at the same time the settlement of primary consolidation of the formations overlying the aquifer subjected to the vertical elastic displacement. Preserves itself, in this way, the balance of the system and shows how the CCS can have a double purpose: on the one hand reduce the emission of CO₂ into the atmosphere, and the other end to provide a energy contribution with the exploitation of a source of renewable energy.
