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.

Synthetic Applications of Lawesson’s Reagent in Organic Synthesis
Lawesson’s reagent (LR) is a well-known classic example of a compound with unique construction and unusual chemical behavior, with a wide range of applications in synthetic organic chemistry. Its main functions were rounded for the thionation of various carbonyl groups in the early days. Now its use can help the chemistry community to understand innovative ideas. These include constructing biologically valuable heterocycles, coupling reactions, and the thionation of natural compounds.

Zone Refining
Zone refining is a technology of deeply purifying metals. Its essence is to use the difference in solubility of impurity elements in the solid and molten state of the main metal to precipitate the impurities or change the distribution of the impurity elements. It provides an effective and easy method for preparing high-purity metals.

ZnO Photocatalysts for the Treatment of Wastewater
The presence of contaminants in wastewater, surface water, groundwater, and drinking water is a serious threat to human and environmental health. Their toxic effects and resistance towards conventional water treatment methods have compelled the scientific community to search for an environmentally friendly method that could efficiently degrade toxic contaminants. In this regard, visible light active photocatalysts have proved to be efficient in eliminating a wide variety of water toxins. A plethora of research activities have been carried out and significant amounts of funds are spent on the monitoring and removal of water contaminants, but relatively little attention has been paid to the degradation of persistent water pollutants. In this regard, nanoparticles of doped ZnO are preferred options owing to their low recombination rate and excellent photocatalytic and antimicrobial activity under irradiation of solar light.

Non-Sieving Mechanism
Non-sieving mechanism is a particle removal process in which particles smaller than the membrane pores are captured by adsorption at the pore surface. The non-sieving mechanism plays an important role for charged solute. There are three accepted non-sieving mechanisms: Donnan exclusion, dielectric exclusion, and hydration mechanism.

Sweat as a Biological Fluid of Alcohol Detection
The continued focus on improving the quality of human life has encouraged the development of increasingly efficient, durable, and cost-effective products in healthcare. Over the last decade, there has been substantial development in the field of technical and interactive textiles that combine expertise in electronics, biology, chemistry, and physics. Most recently, the creation of biosensors capable of quantifying biometric data in biological fluids to detect a specific disease or the physical condition of an individual is being studied. The ultimate goal is to provide access to medical diagnosis anytime and anywhere. Presently, alcohol is considered the most commonly used addictive substance worldwide, being one of the main causes of death in road accidents.

Free Radical
Free radicals can be defined as molecular entities or molecular fragments, capable of independent existence (hence “free”). They contain one or more unpaired electrons in an outer atomic orbital or molecular orbital (hence “radical”). The negative electrical charge of electron(s) may be counterbalanced by the positive nuclear charge of positrons, resulting in a neutral particle; otherwise, having anion or cation radicals.

High Performance Liquid Chromatography with Fluorescence Detection Methods
Steroids are compounds widely available in nature and synthesized for therapeutic and medical purposes. Although several analytical techniques are available for the quantification of steroids, their analysis is challenging due to their low levels and complex matrices of the samples. The efficiency and quick separation of the high performance liquid chromatography (HPLC) combined with the sensitivity, selectivity, simplicity, and cost-efficiency of fluorescence, make HPLC coupled to fluorescence detection (HPLC-FLD) an ideal tool for routine measurement and detection of steroids.
