“…We also integrate a qualitative approach in order to provide a more thorough comprehension of the self-perceptions of the SDGs according to the viewpoints of the participants (second part of the study). This work is viewed as an essential complement to technically-oriented studies on sustainable development that cover areas such as energy, water, the environment, and climate change [1,59].…”

The psychometric properties of the Sustainable Development Goals Psychological Inventory (SDGPI) are verified, by employing quantitative and qualitative approaches, in order to obtain a thorough comprehension of the self-perceptions of the sustainable development goals by the Italian participants in this research. The reliability, dimensionality, and aspects of concurrent validity were tested for the SDGPI. Three unidimensional factors (interest, motivation, and self-efficacy) were shown to be prevalent using exploratory factor analysis. Furthermore, the SDGPI showed adequate concurrent validity and internal consistency in the present study. To broaden the quantitative findings, responses to open-ended questions were analyzed. The results suggest perspectives for future exploration and actions regarding the psychology of sustainable development and sustainability.

“…As they are waste energy, they do not affect the environment any more negatively than when they are left as waste and are not getting harvested. Harvesting waste energy does not disrupt the local ecosystem and does not cause any pollution or global warming [ 7 ]. For this work, the kinetic energy source was mechanical vibration from human activities.…”

This work investigated the mechanical and electrical behaviors of piezoelectric and triboelectric energy harvesters (PEHs and TEHs, respectively) as potential devices for harvesting impact-driven energy. PEH and TEH test benches were designed and developed, aiming at harvesting low-frequency mechanical vibration generated by human activities, for example, a floor-tile energy harvester actuated by human footsteps. The electrical performance and behavior of these energy harvesters were evaluated and compared in terms of absolute energy and power densities that they provided and in terms of these energy and power densities normalized to unit material cost. Several aspects related to the design and development of PEHs and TEHs as the energy harvesting devices were investigated, covering the following topics: construction and mechanism of the energy harvesters; electrical characteristics of the fabricated piezoelectric and triboelectric materials; and characterization of the energy harvesters. At a 4 mm gap width between the cover plate and the stopper (the mechanical actuation components of both energy harvesters) and a cover plate pressing frequency of 2 Hz, PEH generated 27.64 mW, 1.90 mA, and 14.39 V across an optimal resistive load of 7.50 kΩ, while TEH generated 1.52 mW, 8.54 µA, and 177.91 V across an optimal resistive load of 21 MΩ. The power and energy densities of PEH (4.57 mW/cm3 and 475.13 µJ/cm3) were higher than those of TEH (0.50 mW/cm3, and 21.55 µJ/cm3). However, when the material cost is taken into account, TEH provided higher power and energy densities per unit cost. Hence, it has good potential for upscaling, and is considered well worth the investment. The advantages and disadvantages of PEH and TEH are also highlighted as main design factors.

“…, Carbon capture and storage (CCS) is a key technological measure for reducing the emission of greenhouse gases (GHG) from stationary emission sources such as thermal power plants and ensuring a sustainable and reliable global energy supply. CCS has the potential to significantly reduce carbon dioxide (CO2) emissions and mitigate climate change [1] and is, therefore, regarded as one of the most important research frontiers for the development of a sustainable future [2]. Different technologies, including oxyfuel combustion, pre-combustion and post-combustion [3], as well as different materials that are capable of selective sorption of CO2 (chemical or physical) [4] are available for CO2 sequestration.…”

Carbon capture and storage is considered a key technology for decarbonizing the heat and power industries and achieving net zero emission targets. However, the significant energy requirements of the process as currently utilized hinders its widespread implementation. This work presents a novel process configuration by which the energy expenditures of carbon capture and storage can be minimized. This configuration is intended to enhance heat integration during the capture process through an innovative combination of three stripper modifications, namely lean vapor compression, a rich solvent split with vapor heat recovery and reboiler condensate heat recovery using a stripper inter-heater in a single flow-sheet. For carbon dioxide compression, a novel pressurization strategy involving carbon dioxide multi-stage compressors, a heat pump system and a supercritical carbon dioxide power cycle was designed and evaluated. The heat pump was used for carbon dioxide liquefaction while the supercritical carbon dioxide power cycle was employed to recover the intercooling heat. Through a comprehensive parametric investigation of the proposed configuration, the optimum value of the key operating parameters i.e., the split fraction, flash pressure, stripper inter-heater location, stripper inter-heater solvent flowrate, carbon dioxide liquefaction pressure and supercritical carbon dioxide cycle turbine pressure ratio were estimated.The performance of the proposed design at the optimized condition was quantified in terms of the reboiler heat duty, the carbon dioxide pressurization power and the equivalent work and compared to a baseline case post-combustion carbon capture and storage process. The proposed case reduced the reboiler heat duty from 3.36 GJ/TonneCO2 to 2.65 GJ/TonneCO2 and the electric power required for carbon dioxide compression from 16,691 kW to 14,708 kW. The results demonstrate that the new design can significantly
