The development of ethanol as a vehicle fuel in Brazil is the result of a historical trajectory shaped by the interaction of several societal and technological elements. This article addresses this relationship from the perspective of sociotechnical systems, by framing how each sociotechnical element (actors, exogenous shocks, infrastructure, knowledge, social institutions and technologies) enabled the consolidation of ethanol as a fuel alternative to gasoline in Brazil. The section dedicated to institutional change provides a historical overview emphasizing institutional arrangements aimed toward ethanol fuel specifically, as well as an updated review of formal incentive mechanisms. To discuss the expertise system, we analyze the role of private and public actors of research and development (R&D) related with ethanol fuel. We also provide a summary table of the associated sociotechnical elements for researchers interested in applying the sociotechnical transitions framework in the context of biofuels. This article suggests that the strengthening of the sociotechnical system has enabled flexible-fuel vehicles to reach over 70% of the Brazilian light vehicle fleet since their introduction in 2003, a threshold that may indicate an energy transition if changes in fleets, instead of new vehicle sales, are accounted for as an energy transition by itself.

In the present work, we intend to focus on the synthesis, characterization, and application of a high-performing hydrophobic and oleophilic polyurethane foam functionalized with diatomaceous earth and fluorosilane, which are eco-friendly and low-cost materials for their potential use as absorbents for hydrophobic materials. The scanning electron microscopic studies and thermogravimetric analysis showed that the surface-modified polyurethane has a significant micro–nano-structure and surface functionalization, and the water contact angle measurement showed an increase in hydrophobicity due to the fluorosilane-functionalized diatomaceous earth particles anchoring onto the polyurethane foam. Also, the thermogravimetric analysis revealed an increased thermal stability due to the surface functionalization. The novel fluorosilane—diatomaceous earth—polyurethane foam exhibited a silver mirror-like effect when immersed into water due to inherent hydrophobicity and had an enhanced absorption of oil and organic solvents compared to the unmodified polyurethane. This research presents the successful synthesis of surface-modified polyurethane for its suitability for oil absorption capacity for cleaning the oil pollutants from water and for organic solvents clean-up purposes. Graphical abstract Overview of the research approach, which represents stepwise synthesis of the polyurethane (PU) foam surface modified with diatomaceous earth (DE) and fluorosilane (FS) to form low-density and high-absorbing surface-functionalized PU foam exhibiting enhanced oil absorption making this novel composite as a potential candidate for crude oil clean-up and recovery process.

Active learning is a promising teaching approach that can develop sustainability competences in learners. In this paper, we investigate the potential of active-learning pedagogies such as serious games and active-learning toolkits to deliver sustainability knowledge and skills in materials education. We organised a workshop for 20 participants from UK Universities where they played the serious game In the Loop around critical materials and circular economy and engaged in the Active-Learning ToolKit Sustainable Development (Granta Design/now Ansys UK Ltd.) to assess the sustainability of a proposed policy intervention around the use of electric cars. We used a self-assessment questionnaire and reflection sessions to deduce the level of sustainability skill developed by the participants as well as importance and performance analysis (IPA) to help the educators understand crucial components they should concentrate their teaching and learning efforts on in the future. Finally, we provide recommendations for educators on how to implement active learning in materials education in order to empower students with skills for sustainability.

Highlights Use of olive core wastes as sand in self-compacting mortar (SCM). The behavior of SCM with olive core waste is evaluated by the physico-mechanical and thermal properties of different mixes. The bulk density and thermal conductivity are improved by using of olive core wastes. Abstract The recycling of organic wastes in the field of civil engineering is a very important process as long as the products to be obtained are not subjected to stringent quality standards. This research is a part of the general policy of saving energy and protecting the environment. Its aim is to study the possibility of developing a new insulating building material by recycling vegetable waste from the olive processing industry (olive core) that discarded in nature. After having been sorted, dried and then extruded in the form of grains, these wastes are incorporated as fine aggregate (sand) in the manufacturing of self-compacting mortar (SCM) by substituting the mass of sand with different percentages (10, 20, 30 40 and 50%). The physico-mechanical and thermal properties of the obtained SCMs are analyzed and compared to the control. The results of this study show a decrease in density and compressive strength of SCM by increasing the content of olive core wastes. However, the thermal properties of SCM are improved through replacing sand by such wastes, which could allow using olive waste core based SCM in various types of nonstructural components with intriguing insulating properties.

Highlights The hybrid solar heating systems help in increasing energy savings. However, an optimal configuration along with suitable control strategies will be required to enhance the thermal performance of the system. Abstract In the present work, a hybrid solar-gas heating system is built up in Algiers, Algeria, to investigate its thermal performances and thus highlight the annual solar coverage rate. The system consists essentially of two flat plate solar collectors, a gas boiler, and a hot water storage tank. The operation of the installation is controlled by data acquisition card through LabVIEW software. For this purpose, experiment tests have been conducted for different weather conditions on which the hybrid system was operating under three different scenarios simulating working days and weekends. It has been found that temperatures of the storage tank water can reach 36, 34 and 27 °C for days with a global horizontal irradiation of 390, 400 and 533 W/m^2, respectively. These preliminary results showed that temperatures of the tank under the steady state operating modes might contribute to the reduction of energy consumption for a given space heating application.

Widespread deployment of solid state batteries requires facile, high-throughput coating processes. Solid state batteries that utilize energy dense anodes may have similar manufacturing costs as traditional lithium ion batteries. Widespread deployment of renewable energy and electrification of transportation are necessary to decrease greenhouse gas emissions.

However, to achieve giga-scale capacities relevant to the EV market large-scale manufacturing approaches are necessary. Solid-state batteries are likely to adopt coating techniques and processing approaches similar to solid oxide fuel cells and conventional battery systems. While control over microstructure, interfaces, and thickness are paramount for achieving long lifetimes, processing speed governs cost and scalability. This perspective highlights the state-of-the-art for solid-state battery manufacturing approaches and highlights the importance of utilizing conventional battery manufacturing approaches for achieving price parity in the near term. Decreasing material costs and improving cell architecture (biploar) may further decrease manufacturing costs.

Highlights Barocaloric methods offer the widest range among solid-state caloric materials where to pick and choose. However, ideal barocaloric materials do not exist and a trade-off is required; Materials with high refrigerant capacity suffer from poor thermal conductivity and low density, and conversely. Abstract Solid-state caloric effects promise since decades a disruptive cooling technology that should be more efficient and cleaner than current vapor compression. However, despite relevant achievements have been made, it is still difficult to foresee the time left for the development and wide implementation of competitive devices. Recent progress in the response of materials under hydrostatic pressure offers hope for overcoming some of the shortcomings posed by other solid-state methods and augurs a good outlook for barocaloric cooling, but there are still many struggles ahead to address in order to demonstrate its viability as a commercial cooling technique. Here we briefly review the milestones achieved in terms of barocaloric materials and discuss the pending challenges and expectations for the oncoming years. Graphic abstract
