A study on the interfacial properties between a solid glassy electrolyte, LiI‐Li3PS4 (LPSI), and graphite (MAG) composite electrodes was carried out with the aim of reducing or even eliminating the irreversible capacity during the 1st charge‐discharge cycle. The performances of all‐solid‐state MAG|LPSI|Li cells were compared with those of conventional liquid cells. To reinforce a well‐distributed conductive path in MAG as well as at the MAG/LPSI interface, the type of electron conducting additive and the pressure during cell preparation were optimized.

The paper shows the results of the exergetic analysis of the Nuclear Steam Supply System (NSSS) of the MARS Pressurized Light Water Reactor using the theoretical methodology described in the authors’ previous works [1] and [2]. The analysis firstly aims at a novel assessment of the irreversibilities occurred in the nuclear reactor vessel to compare the results, in terms of Exergy Destruction and exergetic Efficiency, with those obtained adopting one of the most employed methodology as reference.

The paper provides an alternative, novel methodology to perform the exergetic analysis of a Pressurized Nuclear Reactor (PWR) based on the strictest definition of fission temperature to get to a careful evaluation of Exergy Destruction and exergetic Efficiency of the component.

We hereby propose a non-expensive method for the deposition of pure and Al-doped hematite photoanodes in the configuration of thin films for the application of dye-sensitized solar cells (DSSC). The electrodes have been prepared from hematite nanoparticles that were obtained by thermal degradation of a chemical precursor. The particles have been used in the preparation of a paste, suitable for both screen printing and doctor blade deposition. The paste was then spread on fluorine-doped tin oxide (FTO) to obtain porous hematite electrodes.
