Abstract Making a consistency with the objectives of circular economy, herein, waste pistachios shells were utilized for development hydrogen evolution reaction (HER) and oxygen reduction (ORR) electrocatalysts which are key bottleneck in technological electrolyzers fuel cells, respectively. As an alternative to scarce expensive platinum-group-metal (PGM) electrocatalysts, metal nitrogen carbons (MNCs) emerging as promising candidate both aforementioned electrocatalysis where iron nickel...
One of the main issues wearable electronic devices regards their power supply and autonomy. The exploitation mechanical energy from body motion vibrations can be realized by using piezoelectric materials coupled with a proper storage device. To this aim, Self-Powered Supercapacitors (SPSCs) have been investigated over last decades, either as internally integrated SPSC (iSPSC), where element device is used Super Capacitor (SC) separator, or via an external integration (eSPSC), unit SC are...
Abstract The electrochemical behaviour of steel, copper, and titanium current collectors was studied in aqueous solutions lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) at various concentrations, from 0.5 up to 20 m. As the concentration electrolyte increases, window water stability widens according “water-in-salt” concept. metal grids have been electrochemically, both under anodic cathodic conditions, by means cyclic voltammetry chronoamperometry. Subsequently, a microscopic analysis...

The chemical–physical electrochemical characterization electrodes, as well the effect Co/Cu in ratios on crystal lattice, electrode morphologies, performance were investigated using X-ray diffraction (XRD), scanning electron microscopic (SEM) cyclic voltammetry (CV), impedance spectroscopy (EIS), galvanostatic...
A series of methanesulfonate salts with various globular cations, including the achiral 3-quinuclidonium [QHco]+, racemic (3)-hydroxyquinuclidinium [QHrac]+, and enantiopure R-[QH]+, have been synthesized structurally characterized. Despite high degree similarity among components, only salt R-[QH]MS was found to undergo a reversible plastic transition at temperature. Electrochemical impedance spectroscopy successfully applied study proton conductivity associated temperature variations phase...
Abstract Microbial fuel cells (MFCs), despite representing a promising technology, suffer from low power generation that hinders, in most of the cases, their application as sources. In fact, MFCs are usually coupled with supercapacitors or batteries and these storage units accumulate energy harvested by deliver it on demand. this work, electrodes MFC used an internal supercapacitor discharges self‐recharges performed investigated. Discharges between 1.5 mA 4 were presented producing maximum...
The aim of this paper is to demonstrate lithium metal battery cells assembled with high potential cathodes produced by sustainable processes. Specifically, LiNi0.5Mn1.5O4 (LMNO) electrodes were fabricated using two different water-processable binders: pullulan (PU) or the bifunctional electronically conductive poly(3,4-ethylenedioxythiophene)-poly(styrene sulfonate) (PEDOT:PSS). cell performance was evaluated voltammetric and galvanostatic charge/discharge cycles at C-rates 1M LiPF6 in 1:1...
