We attempt to rationalize the high activities of La1 À xSrxCoO3 À d through the electronic structure and participation of lattice oxygen in the mechanism of water electrolysis as revealed through ab initio modelling. Using this approach, we report a material, SrCoO2.7, with a high, room...
To reach a current density of 100 mA/cm2, the cell with MoS2/NiFe LDH | MoNiFe coupled electrodes only required a voltage of 1.728 V, which was significantly lower than the reference cell with Pt/C | RuO2 coupled electrodes (1.755 V). Fig. 7: The overall water ...

Experimental Model To test the feasibility of EIT as a means to monitor the onset and extent of electrolysis in tissue, we have devised the following experiment: 1) A reference EIT image of the tissue phantomis taken, 2) Electrolytic stimulation is applied, 3) Another EIT reference image of...
Water electrolysis is a clean and useful technology for producing hydrogen, which is a renewable alternative to fossil energies1,2. However, the oxygen evolution reaction (OER) is a bottleneck in realizing efficient water electrolysis owing to its sluggish kinetics3,4,5,6. The use of noble meta...
Electrochemical OH−adsorption was performed in an N2-saturated 1 M KOH electrolyte. Linear sweep voltammetry was carried out between −0.2 and +0.6 V versus RHE with a sweep rate of 100 mV s−1. Before the experiment, all copper catalysts were reduced at −0.6 V versus...
In the alkaline process, two moles of water are reduced to one mole of H2 and two OH− ions at the cathode [11]. The resulting H2 is released from the cathodic surface. The electric potential between the anode and the cathode force the hydroxile ions through a porous separator to the...
of stepwise presented digital hints (sequential scaffolds), here by means of augmented reality (AR), supported learners during the experiment. Two succeeding AR-hints were offered. This research focuses on the set-up of the experiment by learners and the change of gaze between the AR-hints and...
2. Experiment The NaCl–KCl–AlF3and LiF–AlF3melts were prepared from individual LiF, KCl, NaCl, and AlF3salts of reagent grade. Initially, anhydrous salts were dried at 400 °C for 4 h. Before the state of the experiments, the electrolytes were heated to operating temperature, then purifie...
