“…To overcome the abovementioned problems along with the primary consideration to develop environment-friendly materials are addressed in published papers [37][38][39]. For this purpose, we have selected ZrO 2 and mesoporous carbon, the merits of ZrO 2 are its non-toxic behavior and a good fit on environmental as well as stability parameters, and mesoporous carbon [11,12,24] balances the power density and sustainability owing to its high specific surface area and stability, which is seen also verified with recent literature as large applicability in EDLC type of energy storage devices [40,41].…”

The rapid development of modern technology starves for future research to attain high-energy, high-power, and high cyclic stable energy-storage devices. Carbonaceous electrodes in supercapacitors provide a large-power device, which stores the charge between the surface of the carbonaceous electrode and the electrolyte layer. The commercially available electrode based on pure carbon suffers from low energy density. To overcome the mentioned issue major efforts have been dedicated to enhancing the charge storage of carbonaceous electrodes by the addition of both pure capacitive material (such as Carbon and its derivative) and pure battery-type material (transition-metal Oxide, hydroxides). Mesoporous carbon due to its advanced feature along with ZrO2 good fit on performance and environmental aspect parameters. In this report, we have prepared environmentally friendly mesoporous carbon ZrO2 composite by the facile method, initially, ZrO2 is prepared hydrothermally after that mixing is done at room temperature to obtain the final product mesoporous carbon@ZrO2. The material structural, and microstructural examinations are done by X-ray diffraction analysis, and field emission scanning electron microscopy. The galvanostatic charging-discharging analysis shows the specific capacitance of the device is 125 F/g and the energy density of the device is 25 Wh/kg at a current density of 0.5 A g-1. The GCD shows an extreme power density of 1201 W/kg at 1 mA. The CV analysis shows the maximum specific capacitance of 54.5 F/g at 10 mV/Sec. The long-term cyclic stability of up to 10000 cycles is tested through GCD. The device shows high capacitance retention and Coulombic efficiency till the last GCD cycle at 82 % and 100 % respectively. The capacitive contribution is 55% for optimized electrodes. The prototype device formation and load (LED) testing are done at the laboratory. Based on experimental findings we have proposed a charge storage mechanism for a better understanding of readers.

“…Nowadays, sustainable development can be achieved by relying on every development. In addition, we need to use energy in a sustainable way through reducing consump-tion and finding renewable energy sources [65][66][67][68][69][70] and low carbon energy sources, while developing low consumption equipment and energy efficient projects. As a result, we will feel more inclined to make investments [71] and bring about economic growth [72].…”

The purpose of this paper is to propose a tool to measure the performance of a Strategic Asset Management Plan (SAMP) based on a Balanced Scorecard (BSC). The SAMP converts organizational objectives into asset management objectives, as well as specifies the role of the asset management system, providing support to achieve asset management objectives. The SAMP becomes the heart of the organization and integrates the long-term, medium-term, and short-term plans. In the SAMP, the balance among performance, costs, and risks are taken into consideration in order to achieve the organization’s objectives. On the other hand, the SAMP is a guide to set the asset management objectives while describing the role of the Asset Management System (AMS) in meeting these objectives. Since the SAMP is the central figure of AMS, it is important to measure its performance and should be built and improved through an iterative process. This indicates that it is not just a document, it is “the document” that should be treated as a “living being”, which needs to adapt to internal and external changes quickly. The BSC is an excellent tool where, through the appropriate Key Performance Indicators (KPIs), the progress can be measured, and is supported by four perspectives: Financial, Customer, Internal Business Process, and Learning and Growth.

“…Hence, doping with other metal oxides or forming solid solutions with other compounds can be used to improve the electrocaloric effect properties of BT as well as other properties at near-room temperatures (RT) [8,9]. Among these systems, BaTiO 3 -CaZrO 3 (BCZT) systems have received a lot of attention because of their improved dielectric, ferroelectric, piezoelectric, and energy storage performances due to the presence of several sequences of structural transitions [10][11][12][13][14]. For instance, Abdessalem et al [9] reported an electrocaloric temperature change (ΔT) of 0.565K in Ba 0.9 Ca 0.1 Zr 0.05 Ti 0.95 O 3 under an electric field of 30 kV cm −1 .…”

The lead-free ferroelectric 0.4Ba0.85Ca0.15Zr0.10Ti0.90O3–0.6BaTi0.89Sn0.11O3 (0.4BCZT–0.6BTSn) ceramics were successfully prepared by the sol–gel process. Raman spectroscopy was used to examine the structural properties of the 0.4BCZT-0.6BTSn sample. The findings indicate that the sample was well crystallized into a single perovskite structure. The phase transitions of the studied sample have been investigated using the DSC technique. The electrocaloric effect (ECE) properties were indirectly determined using the Maxwell approach. Under a relatively low applied electric field of 30 kV cm−1, the results show enhanced electrocaloric temperature change and entropy change of ΔT = 1.32 K and ΔS = 1.41 J/kg.K, respectively. Besides, the electrocaloric responsivity (ξ max = 0.45 K·mm/kV) obtained is among the highest reported values in pb-free ferroelectrics near room temperature. These findings demonstrate that the lead-free 0.4BCZT–0.6BTSn ceramic is a promising candidate for solid-state cooling applications.
