Product-Based Learning
The traditional teaching-learning process in higher education employs strategies that position students as recipients of information transmitted by the teacher, which is conceptualized as knowledge. However, the reality in which we live, including new generational groups’ characteristics, requires implementing training solutions that meet individuals' needs in the development of skills or know-how. Thus, deploying suitable solutions to society through a framework that forms individuals capable of continuously seeking knowledge, creating and innovating, is crucial. The "Reproduction of an Environment of Innovation in the Classroom" (RAIS) is a product-based learning and evaluation strategy where the student is actively involved in constructing and generating knowledge. It allows developing the programmatic competencies in engineering courses to attain a feasible product. The RAIS strategy has been applied in Physical chemistry for Chemical Engineers and Industrial Chemistry courses. Students successfully formulated a product using the know-how attained in each course. In addition, this strategy increased motivation compared to other traditional courses, developing the ability to deploy and find solutions in work environments with multidisciplinary groups.

Microalgae Water Bioremediation
The need to reduce costs associated with the production of microalgae biomass has encouraged the coupling of process with wastewater treatment. Emerging pollutants in municipal, industrial, and agricultural wastewaters, ranging from pharmaceuticals to metals, endanger public health and natural resources. The use of microalgae has, in fact, been shown to be an efficient method in water-treatment processes and presents several advantages, such as carbon sequestration, and an opportunity to develop innovative bioproducts with applications to several industries. Using a bibliometric analysis software, SciMAT, a mapping of the research field was performed, analyzing the articles produced between 1981 and 2018, aiming to identifying the hot topics and trends studied until now. The application of microalgae on water bioremediation is an evolving research field that currently focuses on developing efficient and cost-effective treatments methods that also enable the production of add-value products, leading to a blue and circular economy.

Polycrystalline Materials
Polycrystalline materials can be defined as the counterpart of single crystals. These latter  arise from solution crystallization by transfer of a solute from the liquid phase to the crystalline phase. Crystallization from melt originates instead crystallites or grains, that is regular crystalline regions  randomly oriented and separated one anoher by borders with geometric shapes, Polycrystalline materials are the result of a multiple nucleation process, whereas monocrystals are ideally obtainable by dipping a seed crystal into a supercooled melt.  Polycrystalline materials often consist of spherulites, i.e. crystalline aggregates growing with a rounded shape up to impingment with adjacent spherulites. The borders amongst spherulites and the size and the final shape of spherulites affect considerably the properties of polycrystalline materials.

Development of Bottom-Blowing Copper Smelting Technology
Bottom-blowing copper smelting technology was initiated and developed in China in the 1990s. Injection of oxygen-enriched high-pressure gas strongly stirs the molten bath consisting of matte and slag. Rapid reaction at relatively lower temperatures and good adaptability of the feed materials are the main advantages of this technology. Development and optimisation of bottom-blowing copper smelting technology were supported by extensive studies on the thermodynamics of the slag and the fluid dynamic of the molten bath.

Ecolinguistics
Ecolinguistics, or ecological linguistics, emerged in the 1990s as a new paradigm of linguistic research, widening sociolinguistics to take into account not only the social context in which language is embedded, but also the ecological context of the living systems and physical enviornment that life depends on. Michael Halliday's 1990 paper New ways of Meaning: the challenge to applied linguistics is often credited as a seminal work which provided the stimulus for linguists to consider the ecological context and consequences of language. Among other things, the challenge that Halliday put forward was to make linguistics relevant to overarching contemporary issues, particularly the widespread destruction of the ecosystems that life depends on. The main example Halliday gave was that of 'economic growth', describing how 'countless texts repeated daily all around the world contain a simple message: growth is good. Many is better than few, more is better than less, big is better than small, grow is better than shrink', which leads to ecologically destructive consequences.

Bioemulsifiers and Its Applications in Food Industry
Bioemulsifiers have a larger molecular weight than biosurfactants, because they are complex mixes of lipopolysaccharides, lipoproteins, heteropolysaccharides, and proteins. Due to their functional capabilities and eco-friendly properties, bioemulsifiers (BE) are regarded as multifunctional biomolecules of the twenty-first century. Numerous microorganisms produce bioemulsifiers under a variety of diverse and extreme environmental conditions. Bioemulsifiers are widely used in a variety of industries, including medicine, petroleum, food, pharmaceuticals, chemicals, textiles, and cosmetics.

Messerschmitt Me 323
The Messerschmitt Me 323 Gigant ("Giant") was a German military transport aircraft of World War II. It was a powered variant of the Me 321 military glider and was the largest land-based transport aircraft of the war. A total of 213 are recorded as having been made, 15 being converted from the Me 321.

Agriculture 5.0 and Remote Sensing
Constant industrial innovation has made it possible that 2021 has been officially marked by the European Commission as the beginning of the era of “Industry 5.0”. In this 5th industrial revolution, RS has the potential of being one of the most important technologies for today’s agriculture. RS sprouted in the 19th century (specifically in 1858) through the use of air balloons for aerial observations. At present, it occupies a central position in precision agriculture (PA) and soil studies. It is also important to mention some of the interchangeable terms most commonly used include “precision farming”, “precision approach”, “remote sensing”, “digital farming”, “information intensive agriculture”, “smart agriculture”, “variable rate technology (VRT)”, “global navigation satellite system (GNSS) agriculture”, “farming by inch”, “site specific crop management”, “digital agriculture”, “agriculture 5.0”, etc. RS is a vast term that covers various technological systems, such as satellites, RPAs, GNSS, geographic information systems (GIS), big data analysis, the Internet of Things (IoT), the Internet of Everything (IoE), cloud computing, wireless sensors technologies (WST), decision support systems (DSS), and autonomous robots.
