Characterisation of path loss models in wireless sensor networks: scenarios, variables, and open problems
Path loss models (PLMs) play a fundamental role in the deployment of wireless sensor networks (WSNs) since they support tasks related to positioning, tracking, and power control, making the end nodes coexist in complex ...
Integration of the straightforward and environmentally friendly sol–gel/solvothermal and photodeposition methods as a way to prepare highly photoactive Au/S-TiO2 and Cu/S-TiO2 materials
Au/S-TiO2 and Cu/S-TiO2 materials were prepared by integrating the sol–gel/solvothermal and photodeposition methods, which constituted a straightforward and environmentally friendly synthesis route with a low time requirement ...
Mechanism adsorption analysis during the removal of Cd2+ and Cu2+ onto cedar sawdust via experiment coupled with theoretical calculation: Mono- and multicomponent systems
In this work, a deeper comprehension of the adsorption phenomena for Cd2+ and Cu2+ occurring in mono- and multicomponent systems on an adsorbent material obtained from cedar sawdust was accomplished by using spectroscopic ...
