This article presents the first systematic study of the effect of Relative Humidity (RH) on the water content and hydroxide ion conductivity of quaternary ammonium-based Alkaline Anion-Exchange Membranes (AAEMs). These AAEMs have been developed specifically for application in alkaline membrane fuel cells, where conductivities of >0.01 S cm(-1) are mandatory. When fully hydrated, an ETFE-based r...

Abstract The efficiency in converting solar energy into electricity is fundamental wherever photovoltaic panels are present, still more crucial the design of racing vehicles. Even minimal reductions conversion ratio, maintained for long races, cause cars to lose race positions and competitiveness. Here we introduce a numerical-experimental study choosing best combination materials encapsulate c...

This paper describes the fabrication of a novel microbore monolithic column modified with magnetite nanoparticles (MNPs) prepared in poly(ethylene-co-tetrafluoroethylene) (EFTE) tubing, and its application as stationary phase for chromatographic separation phosphorylated compounds. In order to obtain composite column, two-step procedure was performed. The formation glycidyl methacrylate-based m...

The inflation of planar thin films represents a phenomenon widely employed by engineering and biological systems, with applications ranging from pressure sensors material characterization to growing skins in the human body. In this paper, bulging plane circular membranes composed isotropic elastoplastic materials is analytically, computationally experimentally studied. An analytical finite stra...

The article investigates the dependencies of façade design and construction in integration a sustainable solar-powered cooling system based on closed adsorption. presented work focuses possible variants envelope surface -integrated adsorber. principle adsorption is and, this, architectural options for are investigated. This done both constructively visually. For each variant, solar gains summed...
