Water is a vital resource that is becoming increasingly scarce due to global warming, pollution and leaks in pipes, especially in urban areas. Finding non-intrusive methods to detect water flow variation and leakage is therefore essential to reduce losses in urban distribution networks that can have a significant economic impact. In this work, we have explored an acoustic method to detect the vibrations of water flows for metallic pipes. So, two piezoelectric sensors were used, the first one is made of a Lead Zirconate Titanate Ceramic (PZT) and the second one is a Polyvinylidene fluoride...

This study concerns the design of an electrochemical sensor functionalized with a polypyrrole-molecularly imprinted polymer (PPy- MIP) for bisphenol A (BPA) detection. Here, N, N'- methylene-bis-acrylamide was chosen as the chelating agent due to its accessible carbonyl and amine groups. Extraction of BPA templates from the vicinity of the PPy-polymeric matrix was optimized by electrochemistry and Fourier Transform Infrared spectroscopy (FTIR). The limit of detection of the designed sensor was of order of 1 nM and the sensitivity was equal to (9.66 ± 0.86) µA/M respectively. The dissociation...

In this paper, the sensing properties of multi-walled carbon nanotubes (MWCNT) and conductive polymer mixture poly(3,4- ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) nanocomposites towards methanol vapor were measured at room temperature. The proposed MWCNT/PEDOT:PSS sensors were fabricated by coating different volumes of the dispersions on the polyethylene terephthalate (PET) flexible substrate to produce different film thicknesses. The substrate was already coated with screen-printed silver interdigitated electrodes. Compared with MWCNT films, the proposed composite films...

This paper is about electrochemical investigations of nitrite (NO 2 - ) and nitrate (NO 3 - ) detection in water. Herein, a study based on functionalization of carbon screen-printed electrodes (CSPE) with chitosan and tetrasulfonated copper (II) phthalocyanine nanocomposite (Chit/Ts-CuPc). Cyclic voltammetry (CV) surveys were carried out with ferri/ferrocyanide probe and analytes for preliminary investigations to confirm the efficacity of the electrode’s functionalization. Differential pulse voltammetry (DPV) measurements then were performed for more precise and sensitive detection with...

Global industrialization and urbanization have increased significantly the concentration of fine particles in the atmosphere. Various methods have been and are being developed for the measurement of fine particles. This paper explored the use of a quartz crystal microbalance (QCM) to measure the mass concentration of combustion particle suspensions and its contribution to air pollution monitoring techniques.

Surface-enhanced Raman spectroscopy (SERS) is a widely used method for the detection of molecules of environmental concern such as pesticides. One of the key factors to achieve high sensitivity in SERS is the high electromagnetic enhancement formed between plasmonic nanoparticles which is dependent on the wavelength used, shape, size, distance, and type of nanoparticles. In this regard, the scope of this paper is to investigate the enhancement factor achieved between adjacent silver or gold nanoparticles of different geometrical configurations by changing the shapes and sizes of the...

In this paper, a new model of a vibrating micro- cantilever is presented, which can be heavily utilized in a microelectromechanical system (MEMS). With our new prototype, several risks associated with the previous means are eliminated, and the rheological sensation is enhanced. The cantilever beam is made out of silicon (Si) engraved by a laser etching machine in an exponential shape ending with a thin array of eight cantilevers with a size of (500 x 140 x 10) µm³. Based on the behavior of the natural frequency, it is possible to estimate the variation of the density of a fluid or the...

Monitoring pesticide contaminants in diverse environmental systems has become a significant concern. A non-enzymatic electrochemical sensor for pirimicarb pesticide detection has been produced by functionalization of the screen-printed carbon electrodes (SPCE) with graphene oxide, ionic liquid, and gold nanoparticles (GO/IL/AuNps/SPCE). Cyclic voltammetry and electrochemical impedance spectroscopy techniques were applied for the electrochemical characterization of the modified electrode in the presence of [Fe(CN)6] 3-/4- as a redox probe. The system showed an exponential response in a...

Ghannouch in the south-east of Tunisia is colonized by halophytes. Mapping and monitoring with remote sensing approach are previsioned as the ways to trace the spatial and temporal confines of their distribution in order to reveal the extent of salinization and its dynamic. The distinguishing of halophyte vegetation can be done by examining optical remote detecting information as a tree approach applied to European Space Agency Sentinel-2 symbolism. As a result, for an area of interest of 50 × 50 km², at least 68 % was classified as halophyte land cover. This mapping exercise represents an...
