This paper presents the design and fabrication of proximity coupled feed disk resonator coated with Multi Walled Carbon Nanotubes (MWCNTs) and Polypyrrole-Chitosan (PPy-CHI) layers as a napropamide sensor. Computer Simulation Technology (CST) microwave studio was used to obtain the best design of disk resonator and feed line position in 5 GHz resonant frequency. Also, MWCNTs - PPy-CHI layers we...
Humic substances and napropamide interactions in aqueous solution: A fluorescence spectroscopy study
The complexation of organic solutes with dissolved humic substances (HS) is an important process for the fate of these chemicals in natural aquatic systems. We used the Fluorescence Quenching technique to study the interactions between napropamide, a common herbicide, and ten dissolved humic or fulvic acids extracted from different soils and peats. The primary mechanism of napropamide quenching...
Dissolved organic matter (DOM) has been found to significantly affect the soil sorption/desorption of napropamide [2-(a-naphthoxy-N, N-diethylpropionamide] and to enhance its transport through soil columns. A method to qualitatively predict if DOM will enhance the transport of napropamide based on easily determined sorptive characteristics is investigated. Batch sorption experiments were specif...
THE TITLE COMPOUND [SYSTEMATIC NAME: N,N-diethyl-2-(naphthalen-1-yl-oxy)propanamide], C17H21NO2, crystallizes with two independent mol-ecules in the asymmetric unit in which the dihedral angles between the naphthalene ring systems and the amide groups are 88.1 (9) and 88.7 (3)°. Four C-H⋯O hydrogen bonds stabilize the crystal structure.
The photochemical behaviour of the herbicide napropamide is studied on cellulose and silica surfaces, using steady-state and laser-flash diffuse reflectance techniques. The results are used to probe how the reaction sites of the host matrices influence the photo-reactive pathways. Napropamide undergoes reaction when irradiated with UV (lamps) or visible (sunlight) radiation on both solid suppor...
wireless sensor networks (wsns) are one of the most interesting consequences of innovations in different areas of technology including wireless and mobile communications, networking, and sensor design. these networks are considered as a class of wireless networks which are constructed by a set of sensors. a large number of applications have been proposed for wsns. besides having numerous applic...
