“…After obtaining the thermodynamically necessary energy for these treatments, its impact was added to the impact of the rest of impacts that have remained constant. The energy was estimated from the specific heat of the materials involved [67][68][69][70], along with the conditions at which the treatments were performed, as the energy spent to heat the materials was solely considered and no energy losses during the treatments were assumed. In order to show the outcomes of the drop in energy consumption, the relative HTC impact in the theoretical industrial scenario and the same impact in the scenario of electricity measured in laboratory equipment respect to the impact of the most pernicious device for each scenario were calculated.…”

The environmental performance of four different device assembly procedures based on hybrid halide perovskite solar cell (PSC) were assessed from cradle to grave using life cycle assessment (LCA) methodology. In addition, a new environmental indicator was defined to measure the time evolution of an impact category, specifically in this case, human toxicity cancer payback time. PSCs procedures accounted for the probably three more used basic recipes for laboratory perovskite deposition: 1) spin coating of stoichiometric precursor solution, 2) spin coating of precursor solution using lead chloride precursor and 3) the two step deposition method. Also, the two most widely used substrate configurations (planar and mesoporous substrate) were considered. LCA included three realistic scenarios for the end of life: 1) residual landfill, 2) reuse and residual landfill and 3) reuse and recycling. The remaining variable parameters to assemble the device were fixed in common for all four devices, which were the major responsible of the whole PSC impact. Lead of PSCs had no significant contribution in environmental impacts. Beyond shared procedure steps, impacts generated by the twostep method and the use of mesostructured type substrate were higher. End of life scenario with reuse and recycling improved the toxicity impact categories.

“…29 When the epoxy mortars (the conductivity, density, and the specific heat capacity are known) are heated in the area AG simulated by high-frequency structure simulation (HFSS) software, there will be high SAR and the rate of temperature increases. 30 The microwave oven used (WZD1S-03 multimode cavity, Sanle, Nanjing, China) is capable of producing a tunable continuous power output up to a maximum of 1000 W at 2450 MHz frequency. The cavity of the microwave oven is a cuboid of 350 mm Â 340 mm Â 230 mm (length, width and height) that made of stainless steel.…”

Polymer mortars are used frequently to repair pavement owing to their excellent properties (mix flexural strength ≥5.75 MPa, compressive strength ≥25 MPa). To repair concrete pavement with polymer mortars rapidly, uniform microwave energy can be used to reduce hardening time of polymer mortars. In this study, the distribution of electromagnetic fields in an industrial microwave facility was optimized, and an area AG with uniform and intensive electric field was obtained. Then microwave curing process of epoxy mortars containing fly ash in the area AG was optimized, and mechanical strengths of the epoxy mortars cured in the optimum process were tested. The results show that, although the distribution of electromagnetic fields in the microwave facility is non-uniform overall, there still are some brush-fire areas, where electric field distribution is relatively uniform. Epoxy mortars added with 10 wt% fly ash can be cured rapidly (approximately 20 min) in the area AG and exhibit outstanding mechanical strengths, which can be used to repair concrete pavement rapidly.

“…The transportation was re-adjusted to the reduced amount of materials for this scenario. Energy consumption of the three annealing steps and the heating and stirring of perovskite reagents was estimated by using thermodynamic equations which describe the heating process and the synthesis of the c-TiO₂ and the perovskite [225,227,228,[328][329][330][331]. No energy losses were considered during those steps.…”

Rosario Vidal supported me. I consider the determined confidence she deposited on me as fundamental. I also appreciate she cared about me as one of her doctoral children. I would also like to thank her for assuming that chief tutoring role. Some months later Iván Mora joined us as a co-director of the thesis. His contribution have undoubtfully improved the quality of the thesis. Besides, his continuous recommendations of making everything simpler have become everlasting knowledge for me to hold. The task of both of them have eventually been essential for my personal development purposes as a doctoral student.My desire for completing a doctoral degree comes from my experience in a research group called PIMA as a postgraduate. Along with the members of this group I truly discovered what science and a scientist are. This was thanks to people such as Estefanía Sánchez Safont, Luis Cabedo, José Gámez and Jennifer González, among others. I would like to include in this category other scientist with which I collaborated at that time, with my first published article as a result. They are Rosa Mondragón Cazorla, Leonor Hernández and Enrique Juliá. My contact with them has endured along my doctoral period. An especial mention is for Rosa Mondragón Cazorla, whom I acknowledge the interesting conversations in the many days commuting to the University in the train.More people joined the PIMA group, such as Jorge García Cañadas, Braulio Beltran, Fran Romero, Nuno Araújo and Aziz Aldureid, among others. An especial mention is for Adrián Mota Babiloni, whom I want to thank for his encouragement in pursuing the doctoral training and useful recommendations. I appreciate the interesting conversations we had along the lunchtime and for considering me as one member more of their group.Apart from that, I would like to mention the colleagues of the GID research group, where I mostly developed the thesis. Nuria Sánchez-Pantoja developed her doctoral thesis concurrently to me. Others had either undergraduate or postgraduate stays in the group, such as Higinio Martínez, Eva Esteve Recatalà, Javier Sánchez, Ana García, Gemma Tidó and many more. Two Mexican professors visited the group, Claudia Saldaña and Sarah Messina. I acknowledge the good moments spent with them.During my doctoral period I also worked at Instituto de Tecnología Cerámica. I thank them for the good time spent in the spare time in there. In particular, Irina Celades,
